Check out all the on-demand sessions from the Intelligent Security Summit here.

More CISOs will have to deliver revenue growth to protect their budgets and grow their careers in 2023 and beyond, and a core part of that will be getting multicloud security right. It’s the most common infrastructure strategy for rejuvenating legacy IT systems and clouds while driving new revenue models. As a result, multicloud is the most popular cloud infrastructure, with 89% of enterprises relying on it, according to Flexera’s 2022 State of the Cloud Report. 

Organizations and the CISOs running them often decide to pursue a multicloud strategy based on the improved availability of resources and best-of-market innovations available, as it helps them meet compliance requirements more efficiently and gain greater bargaining parity during cloud provider negotiations. CISOs have told VentureBeat in previous interviews that multicloud is also an excellent way to avoid vendor lock-in. Large-scale enterprises also look to gain more excellent geographical coverage of their global operations. 

The more multicloud proliferates, the greater the need to enforce least-privileged access across every cloud instance and platform. That’s one of the main reasons why CISOs need to pay attention to what’s happening with cloud infrastructure entitlement management (CIEM). 

Defining CIEM 

Gartner defines CIEM as a software-as-a-service (SaaS) solution for managing cloud access by monitoring and controlling entitlements. It said CIEM uses “analytics, machine learning (ML), and other methods to detect anomalies in account entitlements, like accumulating privileges and dormant and unnecessary entitlements. CIEM ideally provides remediation and enforcement of least privilege approaches.”

Multicloud is a major zero-trust challenge 

Every cloud hyperscaler has a unique approach to solving their platforms’ IAM, PAM, microsegmentation, multifactor authentication (MFA), single sign-on (SSO), and other main challenges their customers face in attempting to implement a zero-trust network access (ZTNA) framework on and across platforms. 

Gartner predicts that inadequate management of identities, access and privileges will cause 75% of cloud security failures by 2023. The more complex a multicloud configuration, the more it becomes a minefield for zero-trust implementation. CISOs and their teams often rely on the Shared Responsibility Model in briefings and as a planning framework for defining who is responsible for which area of the multicloud tech stacks. 

Many enterprises rely on the Amazon Web Services version because of its straightforward approach to defining IAM. With each hyperscaler providing security just for their platform and tech stacks, CISOs and their teams need to identify and validate the best possible IAM, PAM, microsegmentation, and multifactor authentication (MFA) apps and platforms that can traverse across each hyperscalers cloud platform.

“Existing cloud security tools don’t necessarily address specific aspects of cloud infrastructure,” Scott Fanning, senior director of product management and cloud security at CrowdStrike, told VentureBeat. “Identity isn’t necessarily buried into that DNA as well, and the cloud providers themselves have added so much granularity and sophistication in their controls,” he continued. 

One of CIEM’s design goals is to help close the gaps between multiclouds by enforcing least-privileged access, removing any implicit trust of endpoints and human and machine identities. The goal is to eradicate implicit trust from multicloud infrastructure. That isn’t easy to do without an overarching governance platform, which is one of the reasons CIEM is gaining market momentum today. 

The Shared Responsibility Model defines those areas customers are responsible for versus cloud platform providers at a high level. Implementing zero trust in a multicloud environment often exposes long-standing security gaps between clouds that these models don’t show. Source: AWS Shared Responsibility Model.

The more complex a multicloud configuration, the more challenging it becomes for experienced staff to manage, with errors becoming more commonplace. As a result, CIEM advocates point to the need to automate scale governance and configuration monitoring to alleviate human errors. 

Gartner predicts this year that 50% of enterprises will unknowingly and mistakenly expose some applications, network segments, storage, and APIs directly to the public, up from 25% in 2018. In addition, the research firm predicts that by 2023, 99% of cloud security failures will result from manual controls not being correctly configured. 

Why CIEM’s importance is growing 

Getting in control of cloud access risk is what drives the CIEM market today. CISOs rely on risk-optimization scenarios to balance their budgets, and the value CIEM delivers makes it part of the budgeting mix. In addition, by providing time controls for the governance of entitlements in hybrid and multicloud IaaS environments, CIEM platforms can enforce least privilege at scale. 

Leading CIEM vendors include Authomize, Britive, CrowdStrike, CyberArk, Ermetic, Microsoft (CloudKnox), SailPoint, Saviynt, SentinelOne (Attivo Networks), Sonrai Security, Zscaler and others. 

Advanced CIEM platforms rely on machine learning (ML), predictive analytics, and pattern-matching technologies to identify anomalies in account entitlements, such as accounts accumulating privileges that have been dormant and have unnecessary permissions. From a zero-trust perspective, CIEM can enforce and remediate least-privileged access for any endpoint, human or machine identity.  

Fanning said CrowdStrike’s approach to CIEM enables enterprises to prevent identity-based threats from turning into breaches because of improperly configured cloud entitlements across public cloud service providers. He told VentureBeat that one of the key design goals is to enforce least-privileged access to clouds and provide continuous detection and remediation of identity threats. 

“We’re having more discussions about identity governance and identity deployment in boardrooms,” he told VentureBeat during a accurate interview.

Five reasons why CIEM will continue to gain adoption

CISOs pursuing a ZTNA strategy are out for quick wins, especially with budgets on the line today. CIEM is showing that it has the potential to deliver measurable results in five key areas. 

  • Predicting and preventing identity-based threats across hybrid and multicloud environments delivers measurable results that are being used to quantify risk reduction. 
  • CIEM is also proving effective at visualizing, investigating and securing all cloud identities and entitlements. 
  • CISOs tell VentureBeat that CIEM is simplifying privileged-access management and policy enforcement at scale. 
  • CIEM makes it possible to perform one-click remediation testing before deployment on the most advanced platforms. 
  • CIEM can integrate and remediate fast enough to not slow devops down.

Thu, 08 Dec 2022 17:31:00 -0600 en text/html Killexams : We are still failing to learn the most important lesson in cybersecurity. That needs to change, fast
Image: Getty/gilaxia

One year ago, a newly discovered zero-day vulnerability rocked the world of cybersecurity, but 12 months on, there are clear signs that vital lessons haven't been learned. 

The catchily-titled CVE-2021-44228 was and still is an easy to exploit vulnerability in the widely used Java logging library Apache Log4j, which enables attackers to remotely gain access to and take control of machines and servers. 

Upon discovery, it was a massive concern, because the ubiquitous nature of Log4j meant it was (and is) embedded in a vast array of applications, services and enterprise software tools that are written in Java and used by organizations and individuals around the world.  

Such was the danger posed by Log4j that the National Institute of Standards and Technology (NIST) gave the vulnerability a Common Vulnerability Scoring System (CVSS) score of 10 – classing it as a highly severe, critical vulnerability – and within hours of disclosure, it was being exploited by cyber criminals. 

Also: Cybersecurity: These are the new things to worry about in 2023

No wonder CISA chief Jen Easterly described the Log4j vulnerability as "one of the most serious that I've seen in my entire career, if not the most serious" – and it affected hundreds of millions of devices.

Security updates and mitigations were swiftly rolled out, yet a year on from the initial disclosure, Log4j still remains a threat because many organizations and and their suppliers are still yet to apply the updates. 

Many might still not even be aware that the logging library is part of their software ecosystem.  

But repeated warnings made it clear that the critical vulnerabilities posed a threat – and hacking groups ranging from cyber-criminal gangs and ransomware groups to nation-state backed cyber-espionage operations have all actively targeted Log4j vulnerabilities and continue to do so. 

Just last month – almost a year on from the initial disclosure – CISA and the FBI put out a security alert, warning that if organizations hadn't yet patched or mitigated Log4j vulnerabilities, they should assume their network is compromised and act accordingly. 

The alert came after an investigation into a cyberattack against what CISA and the FBI describe as a 'federal civilian executive branch' organization. If a government body can't plug the security holes correctly, then what chances do other organizations have? 

Also: Software development is still ignoring security. That needs to change fast

Cybersecurity moves quickly – it's tough work and information security teams regularly face burnout because there's always another new security vulnerability, or a new security update that needs applying. But cyber criminals don't forget about old security flaws and vulnerabilities – and as long as Log4j instances remain unmitigated, they'll be targeting them. 

That means organizations can't just ignore vulnerabilities and issues and hope they just go away. Fixing these issues is a challenge, but taking notice of security alerts and warnings to ensure your network is protected is an absolute must. 

It's just one of the reasons why the responsible thing for organizations of any size to do is to provide the budget for a suitably sized information security team, which can help detect and mitigate threats before they affect your business and its customers.

Killexams : When access is a privilege; Senhasegura bolsters its PAM platform

Check out all the on-demand sessions from the Intelligent Security Summit here.

Credentials are candy to hackers; whether granted to people, machines or automated processes, they unlock the doors to access, management and alteration (and theft) of confidential data and critical features.

And within organizations, there are a multitude of accounts, devices and users with various types and levels of privileged credentials — but management of sprawling systems can often be a challenge, thus increasing exposure to leaks and attacks.

“It is precisely because privileged credentials offer such powerful access to critical resources that they are one of the favorite targets of malicious attackers,” said Marcus Scharra, cofounder and co-CEO of Senhasegura

This increasing risk has given rise to privileged access management (PAM), a set of information security strategies and tools that manage and protect identities within an organization.

“Simply put, PAM is a solution that provides layers of protection to the operational environment to prevent cyberattacks, risk of data breaches, and financial losses from high-resource accounts,” said Scharra, whose company today announced a $13 million series A investment from Graphene Ventures to help bolster its PAM platform. 

Higher levels of protection with PAM

Experts describe PAM as a subcategory of identity access management (IAM); platforms typically feature automated password management such as vault capability, auto-rotation and generation.

The market for such tools is expected to reach $19.7 billion by 2030. Some top vendors include IBM, Delinea (formerly Thycotic), CyberArk, Broadcom and Osirium. 

Market growth is being driven by growing government regulations, rising cloud adoption and hybrid work structures — and, most notably, increases in cyberattacks due to internal threats. 

In fact, according to Verizon’s 2022 Data Breach Investigations Report, an incredible 82% of cybersecurity breaches are due to a human element. The World Economic Forum puts it at even higher than that: 95%. 

“Privileged accounts have privileged access that can negatively impact production systems or other business outcomes, including access to sensitive information,” according to Gartner.

Ideally, the firm says, privileged access should be just in time — that is, authorized users gain it for a short time, then lose it (until they require it again). And, while some exceptions will have to be made, these should be kept as low as possible. 

“The ratio of always-on accounts to individuals who may use them, is a protection level for unauthorized access to sensitive, powerful accounts and a value measure for your investment in privileged access management,” according to Gartner. 

Strict access controls

Senhasegura’s flagship 360º Privilege Platform automates and centralizes strict access controls to help meet compliance requirements, said Scharra. The platform is differentiated because it is available in both software or hardware, he said (he pointed out that most PAM providers offer only software versions). Also, the company has built the tool from scratch. 

The platform manages the full certificate life cycle: discovery, expiration, automatic renewal and republishing. As Scharra noted, this helps reduce business outages and enables greater efficiency and security. 

Senhasegura also scans, identifies and imports all credentials into a security vault, eliminating unmanaged credentials and simplifying the process of removing credentials when an employee leaves a firm or is no longer authorized, said Scharra.

An identity management and discovery feature automatically maps and identifies all assets connected to the environment and their respective credentials, he explained. And a devops secrets-management component helps Excellerate devops security by scanning and discovering sensitive information such as passwords, API keys and SSL certificates, and devops secrets. 

Imagine, for example, the scenario of a fired and unhappy employee who hasn’t had their privileged accesses removed, said Scharra. They could easily become an attack vector. 

“PAM increases visibility to cyber administrators and reduces operational complexity,” said Scharra. “It forms a strong wall of defense against attackers.” 

Still, it isn’t all about just tools; organizations must adopt a widespread cybersecurity culture, he said, calling this “a key safety precaution.”

“There is no point in investing in cutting-edge protective technologies if the users are not trained to follow basic security practices,” said Scharra. 

He said this includes publicly known practices such as avoiding opening emails from “dubious senders,” avoiding connecting corporate devices to public or unknown networks, and not sharing or repeating passwords. 

“The best security strategy combines education with technologies such as PAM to defend against attack,” he said. 

The São Paulo, Brazil-based Senhasegura —  whose customers include one of Brazil’s largest national defense contractors — will use the new infusion of funding to strengthen its presence in LATAM, North America and the Middle East. 

The company launched MySafe personal password vault in October, and it will continue expanding its platform in 2023, said Scharra. 

He noted that, between 2018 and 2021, the company experienced a 71% CAGR in bookings and 5.6 times growth in annual recurring revenue (ARR). It was also awarded the 2022 Frost and Sullivan Customer Value Leadership Award for Privileged Access Management (PAM) Industry Excellence in Best Practices. 

“Currently, our partners span 55-plus countries, and we have operations in the Americas, Europe and Asia,” said Scharra. “I look forward to further increasing our territorial coverage to reach and serve new customers.”

Killexams : Too many secrets: What can today’s cyber teams learn from a 30-year-old film?

“The world isn’t run by weapons any more, or energy, or money. It’s run by little ones and zeros, little bits of data,” says Ben Kingsley as Cosmo in the film Sneakers.

Directed by Phil Alden Robinson and co-written by Robinson, Lawrence Lasker and Walter F Parkes, Sneakers was released in 1992, although its development began a decade earlier. It was during the development of a previous film, WarGames, that Lasker and Parkes learned of the existence of “sneakers” – teams of hackers, phreakers (exploiters of telecommunication systems) and ex-law enforcement agents, hired to break into secure facilities and top-secret installations.

The film Sneakers follows Martin Bishop (Robert Redford) as he leads a team of security experts specialising in testing security systems. When rogue government agents blackmail Bishop into stealing a black box from a top-secret project called Setec Astronomy, Whistler (David Strathairn) discovers that it has the capability to break encryption systems. Framed for the murder of Setec Astronomy’s inventor, Bishop and his team are on the run and need to retrieve the black box from the blackmailers before it is too late.

Although the film has aged technologically, with its chunky desktop PCs and reliance on corded landline telephones, the concerns it raises about privacy and security, such as the threats to encryption from new technology, remain pertinent. There are also plenty of references to hackers and their culture. For example, the character of Whistler, who is blind, was inspired by the early phreaker Joe Engrassia (aka Joybubbles).

“Sneakers is a great, fictional example of what happens with encryption backdoors or vulnerabilities,” says network architecture consultant Chris Clemson. “Everyone wants them and they don’t stay secret for ever.”

A work of fiction with an accurate representation of security

One of the reasons Sneakers is so accurate is that Robinson interviewed a variety of technical experts to ensure the film’s verisimilitude. Len Adleman, who co-invented the RSA encryption algorithm, created the mathematical formulae for the presentation given by Gunter Janek (Donal Logue) in the film. Meanwhile, Robert Abbott, who designed the first time-sharing operating system for the Control Data Corporation CDC-6600, acted as a technical consultant throughout the film.

Bishop’s team of sneakers are in many ways the equivalent of modern-day penetration testers, who assess the security of corporate and government networks against potential vulnerabilities by attempting to breach those networks. As Sneakers was filmed before the internet became so pervasive, rather than attacking a corporate network, Bishop’s team break into buildings and report their findings.

It is interesting to note how Carl (River Phoenix) is caught by Bishop’s team hacking into his school’s network to change his grades. Rather than having Carl arrested, they recruit him into the team. This mirrors how some modern-day security organisations operate, by recruiting hackers they encounter, allowing them to benefit from channelling their technical skills.

One of the main plot threads in Sneakers is Bishop and his team’s discovery of exactly what Setec Astronomy is. The film portrays Setec Astronomy’s black box as being able to instantly decode encryption, effectively rendering the technology obsolete. “The numbers are so unbelievably big, that all the computers in the world could not break then down,” explains Janek in Sneakers. “But maybe, just maybe, there’s a shortcut…”

Setec Astronomy’s black box is, in many ways, analogous with quantum computing. The computational power of quantum computers will far outstrip that of today’s most powerful computers, which means they can break encryption far more quickly than conventional computers. Therefore, just as in Sneakers with the Setec Astronomy black box, whoever is the first to develop a viable quantum computing system may be able to bypass encrypted security.

Business sectors that deal in confidential or sensitive information – such as defence, financial medical and medical institutions – are already considering the impact that quantum computers could have on current encryption protocols and how that would influence their operations. While there has been a push for greater adoption of two-factor authentication (2FA), or air-gapping for high-security applications, some are exploring the efficacy of post-quantum encryption algorithms.

The fallibility of information security is reinforced in Sneakers when a character profile is created from just a single piece of information. Starting with a car licence plate, they identify the driver as Werner Brandes (Stephen Tobolowsky) and obtain his address by hacking into the Department of Motor Vehicles (DMV). From there, they are able to acquire his rubbish, allowing them to read letters and fabricate a meeting with him. This sequence highlights the dangers posed by sensitive information, both physical and electronic copies, if information is not properly disposed of and destroyed.

There is no such thing as absolute security

Just as in real life, Sneakers portrays humans as a weak point in an organisation’s security, because of their susceptibility to social engineering. The security guard where Janek works is deliberately distracted to allow Bishop to enter without a security card, while Brandes has his security card stolen and is tricked into sharing biometric data.

Sneakers also demonstrates how biometrics are not as infallible as they might appear. Using a high-quality recording of Brandes’ voice, Bishop is able to spoof a voice-print identifier. There is still a danger of an over-reliance on modern-day biometrics. They are marketed as an ideal security methodology, as the “key” is unique to each person, be it through a fingerprint reader or facial recognition system.

However, there are reported instances of these having been bypassed. Facial recognition systems can be fooled by 3D rendering using photographs from social media, and fingerprint locks have been bypassed by tricking the scanner using a fingerprint pressed into gelatine-based material.

Another thought-provoking moment in Sneakers is when Bishop encounters a keypad lock, but is able to get round it by simply kicking the door open, as the doorframe has not been reinforced. Although the moment is played comedically, it raises a valid point of security. Just because the door lock was secure, it does not mean everything else was protected. An analogy from the world of cyber security is the need to consider all network connections beyond the primary access points.

Sneakers also predicted the threat posed by keyloggers, which can record keyboard strokes to detect a user’s passwords. The film shows Janek being videotaped typing his password, until the view is unexpectedly blocked. Although modern-day keyloggers are far more sophisticated, due to the prevalence of the internet, the core threat remains similar.

The internet is everywhere

In Sneakers, it eventually emerges that an organised crime group (OCG) is behind the death of Janek and the conspiracy to steal the black box. Nowadays, OCGs are responsible for most online crime. Just as in the film, criminals are still using the internet to coordinate their activities, but OCGs now also operate numerous online crimes, such as the DarkSide ransomware attack against the Colonial Pipeline.

It is notable that certain governments in Sneakers are also interested in Setec Astronomy. The film later reveals that a US government agency funded it. A cultural attaché, heavily implied to be a spy, also offers Bishop political asylum because of Bishop’s involvement in stealing the black box. As Crease (Sidney Poitier) states in Sneakers: “There isn’t a government on this planet that wouldn’t kill us all for that thing.”

We have already witnessed cyber attacks that are motivated by political ideology and are strongly suspected to have been directly or indirectly sponsored by nation states. As our society becomes ever more reliant on digitally connected devices, cyber attacks against government departments and critical infrastructure are becoming increasingly disruptive.

One of the underlying themes of Sneakers is our perception of information, which essentially predicted social media campaigns and the spread of disinformation. “There’s a war out there, old friend, a world war – and it’s not about who’s got the most bullets, it’s about who controls the information,” says Cosmo in Sneakers. “What we see and hear, how we work, what we think, it’s all about the information.”

Cosmo wants to redistribute wealth by bringing down the economy – not by attacking financial institutions directly, but by sowing distrust.

There have been several disinformation campaigns, such as those that proliferated during accurate UK and US elections, as well as at the time of the Brexit vote and the Covid-19 pandemic. These incidents have all demonstrated the degree to which large numbers of people can be influenced by disinformation campaigns and the impact that so-called “alternative facts” can have on society.

Although Sneakers is set in a world before social media and smartphones, the concerns it raises about the nature of security and privacy are chillingly prescient. We are still facing concerns about the possible obsoletion of encryption and what that would mean for information security. Although the technology has aged significantly, Sneakers’ adherence to the core principles of security, with their use of social engineering attacks, ensures that the film’s themes are as true today as they were when it was first released in 1992.

Killexams : SOC Turns to Homegrown Machine Learning to Catch Cyber Intruders

Using an internally developed machine learning model trained on log data, the information security team for a French bank found it could detect three new types of data exfiltration that rules-based security appliances did not catch.

Carole Boijaud, a cybersecurity engineer with Credit Agricole Group Infrastructure Platform (CA-GIP), will take the stage at next week's Black Hat Europe 2022 conference to detail the research into the technique, in a session entitled, "Thresholds Are for Old Threats: Demystifying AI and Machine Learning to Enhance SOC Detection." The team took daily summary data from log files, extracted interesting features from the data, and used that to find anomalies in the bank's Web traffic. 

The research focused on how to better detect data exfiltration by attackers, and resulted in identification of attacks that the company's previous system failed to detect, she says.

"We implemented our own simulation of threats, of what we wanted to see, so we were able to see what could identify in our own traffic," she says. "When we didn't detect [a specific threat], we tried to figure out what is different, and we tried to understand what was going on."

As machine learning has become a buzzword in the cybersecurity industry, some companies and academic researchers are still making headway in experimenting with their own data to find threats that might otherwise hide in the noise. Microsoft, for example, used data collected from the telemetry of 400,000 customers to identify specific attack groups and, using those classifications, predict future actions of the attackers. Other firms are using machine learning techniques, such as genetic algorithms, to help detect accounts on cloud computing platforms that have too many permissions.

There are a variety of benefits from analyzing your own data with a homegrown system, says Boijaud. Security operation centers (SOCs) gain a better understanding of their network traffic and user activity, and security analysts can gain more insight into the threats attacking their systems. While Credit Agricole has its own platform group to manage infrastructure, handle security, and conduct research, even smaller enterprises can benefit from applying machine learning and data analysis, Boijaud says.

"Developing your own model is not that expensive and I'm convinced that everyone can do it," she says. "If you have access to the data, and you have people who know the logs, they can create their own pipeline, at least in the beginning."

Finding the Right Data Points to Monitor

The cybersecurity engineering team used a data-analysis technique known as clustering to identify the most important features to track in their analysis. Among the features that were deemed most significant included the popularity of domains, the number of times systems reached out to specific domains, and whether the request used an IP address or a standard domain name.

"Based on the representation of the data and the fact that we have been monitoring the daily behavior of the machines, we have been able to identify those features," says Boijaud. "Machine learning is about mathematics and models, but one of the important facts is how you choose to represent the data and that requires understanding the data and that means we need people, like cybersecurity engineers, who understand this field."

After selecting the features that are most significant in classifications, the team used a technique known as "isolation forest" to find the outliers in the data. The isolation forest algorithm organizes data into several logical trees based on their values, and then analyzes the trees to determine the characteristics of outliers. The approach scales easily to handle a large number of features and is relatively light, processing-wise.

The initial efforts resulted in the model learning to detect three types of exfiltration attacks that the company would not otherwise have detected with existing security appliances. Overall, about half the exfiltration attacks could be detected with a low false-positive rate, Boijaud says.

Not All Network Anomalies Are Malicious

The engineers also had to find ways to determine what anomalies indicated malicious attacks and what may be nonhuman — but benign — traffic. Advertising tags and requests sent to third-party tracking servers were also caught by the system, as they tend to match the definitions of anomalies, but could be filtered out of the final results.

Automating the initial analysis of security events can help companies more quickly triage and identify potential attacks. By doing the research themselves, security teams gain additional insight into their data and can more easily determine what is an attack and what may be benign, Boijaud says.

CA-GIP plans to expand the analysis approach to use cases beyond detecting exfiltration using Web attacks, she says.

Killexams : What Every Enterprise Can Learn From Russia’s Cyber Assault on Ukraine

Throughout the ongoing war on Ukraine, known and suspected Russian nation-state actors have compromised Ukrainian targets. They’ve used a combination of techniques including phishing campaigns, exploiting unpatched vulnerabilities in on-premises servers, and compromising upstream IT service providers. These threat actors have also developed and used destructive wiper malware or similarly destructive tools on Ukrainian networks.

Between late February and early April 2022, Microsoft saw evidence of nearly 40 discrete destructive attacks that permanently destroyed files in hundreds of systems across dozens of organizations in Ukraine. After each wave of attacks, threat actors modified the malware to better avoid detection. Based on these observations, we’ve developed strategic recommendations to global organizations on how to approach network defense in the midst of military conflict.

Common Russian Intrusion Techniques

Russia-aligned cyber operations have deployed several common tactics, techniques, and procedures. These include:

  • Exploiting public-facing applications or spear-phishing with attachments/links for initial access.
  • Stealing credentials and leveraging valid accounts throughout the attack life cycle, including within Active Directory Domain Services and through virtual private networks (VPNs) or other remote access solutions. This has made identities a key intrusion vector.
  • Using valid administration protocols, tools, and methods for lateral movement, relying on compromised administrative identities in particular.
  • Utilizing known, publicly available offensive capabilities, sometimes disguising them with actor-specific methods to defeat static signatures.
  • “Living off the land” during system and network discovery, often using native utilities or commands that are nonstandard for the environments.
  • Leveraging destructive capabilities that access raw file systems for overwrites or deletions.

5 Ways to Safeguard Your Operations

Based on our observations in Ukraine so far, we recommend taking the following steps to safeguard your organization.

1. Minimize credential theft and account abuse: Protecting user identities is a critical component of network security. We recommend enabling multifactor authentication (MFA) and identity detection tools, applying least-privilege access, and securing the most sensitive and privileged accounts and systems.

2. Secure Internet-facing systems and remote access solutions: Ensure your Internet-facing systems are updated to the most secure levels, regularly evaluated for vulnerabilities and audited for changes to system integrity. Anti-malware solutions and endpoint protection can detect and prevent attackers, while legacy systems should be isolated to prevent them from becoming an entry point for persistent threat actors. Additionally, remote access solutions should require two-factor authentication and be patched to the most secure configuration.

3. Leverage anti-malware, endpoint detection, and identity protection solutions: Defense-in-depth security solutions combined with trained, capable personnel can empower organizations to identify, detect, and prevent intrusions impacting their business. You can also enable cloud-protections to identify and mitigate known and novel network threats at scale.

4. Enable investigations and recovery: Auditing of key resources can help enable investigations once a threat is detected. You can also prevent delays and decrease dwell time for destructive threat actors by creating and enacting an incident response plan.

As the war in Ukraine progresses, we expect to discover new vulnerabilities and attack chains as a result of the ongoing conflict. This will force already well-resourced threat actors to reverse patches and carry out “N-day attacks” tailored to underlying vulnerabilities. All organizations associated with the conflict in Ukraine should proactively protect themselves and monitor for similar actions in their environments.

Microsoft respects and acknowledges the ongoing efforts of Ukrainian defenders and the unwavering support provided by the national Computer Emergency Response Team of Ukraine (CERT-UA) to protect their networks and maintain service during this challenging time.

Looking for the gift that keeps on giving? For the person who has everything (or for anyone, really), the best gifts are experiential.

MasterClass is a vast buffet of smart, inspiring, beautifully produced multi-session online courses taught by experts and celebs at the top of their field, covering everything from music to space exploration, cooking to skateboarding, personal branding to public speaking. Think lessons on restaurant-caliber home cooking with Gordon Ramsay, singing with Mariah Carey, basketball with Steph Curry and creative writing with Margaret friggin' Atwood.
