While many of us were enjoying some time off for Thanksgiving, the US government took drastic action against Huawei and four other Chinese companies. The hardest hit are Huawei and ZTE, as the ban prevents any new products from being approved for the US market. The other three companies are Dahua and Hikvision, which make video surveillance equipment, and Hytera, which makes radio systems. FCC Commissioner Brendan Carr noted the seriousness of the decision.

[As] a result of our order, no new Huawei or ZTE equipment can be approved. And no new Dahua, Hikvision, or Hytera gear can be approved unless they assure the FCC that their gear won’t be used for public safety, security of government facilities, & other national security purposes.

There is even the potential that previously approved equipment could have its authorization pulled. The raw FCC documents are available, if you really wish to wade through them. What’s notable is that two diametrically opposed US administrations have both pushed for this ban. It would surely be interesting to get a look at the classified reports detailing what was actually found. Maybe in another decade or two, we can make a Freedom of Information Act request and finally get the full story.

Fuzzing for Recollapse

[0xacb] has a fun new technique to share, that he calls REcollapse. It’s all about regular expressions that get used in user input validation and sanitation. Regex is hard to really get right, and is full of quirks in how different languages and libraries implement it. A simple example is an email address that contains “punycode” — non-ASCII Unicode characters. It’s perfectly legitimate for an address to contain Unicode, but many normalization schemes collapse unicode strings down into the nearest approximation of ASCII. Take exámple.com and example.com. If some part of a web service sees these as the same thing, and another backend service keeps sees them as unique, that mismatch could allow account takeover. Enter your email here to receive a password reset link.

The novel thing here is a structured approach to fuzzing for these problems. [0xacb] suggests identifying “regex pivot positions”, places in a string where there could be unexpected or inconsistent regex matching. A very different example of this is the end-of-string symbol, $. A developer might use this to specify that a given pattern should only be matched when it’s at the very end of a string. But what happens when there’s a newline embedded in the string? It depends on the language. Yikes!

REcollapse is now available as an Open Source tool, and works great to feed fuzzing inputs into an automated tool. Run it against a target, and watch for different responses. Find something good enough, and profit!

Phishing With Smart Watches

The team at Cybervelia have cooked up yet another way to spear-phish a target. Many of us have smart watches, and one of the most useful functions of those wrist-mounted marvels is to glance at a SMS or other message without fishing out a phone. Could an attacker, with a Bluetooth Low Energy antenna, spoof a text message to a nearby smart watch? After some reverse engineering work, absolutely. With the right message, like “need help, 2nd floor”, the target might just start moving without checking the phone and discovering the spoof.

Real-time Malware Hunting

This one’s fun, as the researchers at Phylum found yet another malicious PyPi package campaign back on the 15th. Their tooling alerted them to the activity very early in the campaign, as packages were being uploaded and the payload was still being fine-tuned. That payload was being developed on Github, so there was only one thing to do.

The union of memes and security research is a wondrous thing. The packages were reported, removed, and it looks like this particular malware campaign was eliminated before it really got started.

This does lead to a hilarious tangent from Phylum, about some of the laughably terrible attempts at malware they’ve discovered in other campaigns. There’s a certain poetic justice to be found in malware refusing to run, because the deobfuscation routine checks for the acknowledgement string and errors out when it’s tampered with.

Lastpass Breach Continued

Lastpass has updated their security incident report, noting that there seems to have been follow-on access of data. They noticed “unusual activity within a third-party cloud storage service”, which usually means Amazon’s AWS. The story here seems to be that a token to the storage service was snagged during the August compromise, and was just now used for more mischief. This does raise some uncomfortable questions about how well Lastpass understands what data was accessed in the earlier breach. That said, cleaning up after an incident is a complicated task, and missing a single AWS token in the action is all too easy.

Another “Legitimate” Commercial Spyware Vendor

In the just-what-we-needed category, the latest report from Google’s Threat Analysis Group names Variston as previously unknown player in the commercial malware game. Like NSO Group and others, Variston seems to have access to 0-day exploits in multiple devices and platforms.

A trio of bug reports were opened in the Chrome bug system, and each contained a mature framework and exploit code for a serious bug. Each of these were known and fixed bugs, but piecing together the clues would indicate that they were being used as 0-days by a vendor, probably Variston. It’s not uncommon for the “legitimate” spyware authors like the NGO Group, the NSA, and others, to properly report bugs once they’ve finished exploiting them, or assumably once a target has discovered the exploit.

500 Years Later

There’s a concept in encryption, that pretty much any encryption scheme is theoretically breakable, given enough time and technological innovation. As an example, see the rate at which quantum computers are developing, and the predicted breakdown of some classical crypto. The philosophy that spills out of this reality is that crypto just needs to be strong enough, that the secrets being protected are entirely stale by the time technology and computing power catch up. Which finally brings us to the story, that Emperor Charles V got nearly 500 years out of his cipher. Probably strong enough.

It turns out that this cipher had some clever elements, like multiple symbols that didn’t mean anything at all, just to make it harder to figure out. The real breakthrough was finding a cipher text that had been loosely translated. It was enough to finally figure out the basic rules. So what was in the central letter that was finally deciphered? Political maneuvering, fears of assassination, and a conspiracy to spread fake news to downplay a setback. Some things never change.

Font Fingerprint

There was a Reddit post over the break that caught our attention, where a user wired money online from his bank in England to Kenya, to pay for a trip. It was a legitimate transaction, but triggered the fraud protection from his bank. In the conversation with the fraud department, one of the flags for possible fraud surprised the Redditor in question: You have TeamViewer installed on your computer.

Now wait. That’s a bit disconcerting, a website can see your list of installed programs? No, not directly. There is no web API to list applications, at least, not since ActiveX died. However, there is an API to list installed fonts. And since Teamviewer brings its own font, it’s pretty easy to detect when it’s installed. And let’s face it, a remote controlled desktop is a reasonable flag for malicious activity. So now you know, your fonts may just be fingerprinting you.

Bits and Bytes

The Google Play store has ejected a pair of mildly popular apps, that were spying on users’ SMS messages. The data collection was incidental, and the real point was to enable fake accounts on various web services, using the victim’s cell phone numbers. Need a hundred Twitter accounts? Rent access to a hundred compromised phones, to use those numbers for the activation flow.

Need to get something past a plagiarism checker? Just rot13 and change the font! It’s a silly demonstration, but it does indeed work. Make your own font to change the letter mapping, and then apply the reverse mapping to the underlying text. To the human eye, it’s the same, but to an automated tool it’s garbage. Save as PDF, and off you go. While circumventing a plagiarism filter is a bad idea, this could have other, more positive uses, like censorship circumvention.

Black Hat 2022 videos are available, only three months later. There are some fun presentations in here, like the Starlink hack, analysis of real-world malware campaigns, and lots of software getting compromised. Enjoy!

Killexams : US bans new Huawei equipment sales over ‘unacceptable risk’ to national security

The Biden administration has banned approvals of new telecommunications equipment from China’s Huawei Technologies and ZTE because they pose “an unacceptable risk” to US national security.

The US Federal Communications Commission (FCC) said on Friday it had adopted the final rules, which also bar the sale or import of equipment made by Chinese surveillance equipment maker Dahua Technology, video surveillance firm Hangzhou Hikvision Digital Technology and telecoms firm Hytera Communications Corp.

The move represents Washington’s latest crackdown on the Chinese tech giants amid fears that Beijing could use them to spy on Americans.

“These new rules are an important part of our ongoing actions to protect the American people from national security threats involving telecommunications,” the FCC chairwoman, Jessica Rosenworcel, said in a statement.

Huawei declined to comment. ZTE, Dahua, Hytera and the Chinese embassy in Washington did not immediately respond to requests for comment.

Hikvision said in a statement that its products did not threaten US security. “This decision by the FCC will do nothing to protect US national security, but will do a great deal to make it more harmful and more expensive for US small businesses, local authorities, school districts and individual consumers to protect themselves, their homes, businesses and property,” Hikvision said.

The firm would continue to serve US customers “in full compliance” with US regulations, it said.

Rosenworcel circulated the proposed measure, which effectively bars the firms from selling new equipment in the US, to the other three commissioners for final approval last month.

The FCC said in June 2021 it was considering banning all equipment authorisations for all companies on the covered list.

That came after a March 2021 designation of five Chinese companies on the so-called “covered list” as posing a threat to national security under a 2019 law aimed at protecting US communications networks: Huawei, ZTE, Hytera Communications Corp Hikvision and Dahua.

All four commissioners at the agency, including two Republicans and two Democrats, supported Friday’s move. The agency said it has authority to revoke prior authorizations, but declined to do so.

Killexams : US Bans Huawei Equipment, Cites 'National Security Risk'

The Federal Communications Commission (FCC) has prohibited the importation or sale of communications equipment made by Huawei and ZTE, due to them posing an “unacceptable risk” to US national security.

The five-member FCC voted unanimously this week to adopt rules that block the importation or sale of communications equipment deemed to pose a national security risk.

The restrictions, which affect Hikvision, will prevent authorities from installing technology that is produced by companies subject to China’s National Intelligence Law. The law  requires Chinese citizens and organizations to cooperate with the country’s intelligence and security services.

In a statement reported(Opens in a new window) by Reuters, Hikvision slammed the FCC:  "This decision by the FCC will do nothing to protect U.S. national security, but will do a great deal to make it more harmful and more expensive for U.S. small businesses, local authorities, school districts, and individual consumers to protect themselves, their homes, businesses and property. The Chinese company added that it will continue to serve American customers "in full compliance" with US regulations.

Killexams : FCC bans authorizations for Huawei and ZTE phones due to security risks

The Federal Communications Commission has banned the sale and importation of telecommunications equipment from Chinese companies Huawei and ZTE, citing national security concerns.

The new bans come nearly a year after President Joe Biden signed into law a bill that prevented the authorization of telecommunication devices that pose a national security risk.

"The FCC is committed to protecting our national security by ensuring that untrustworthy communications equipment is not authorized for use within our borders, and we are continuing that work here,” FCC Chairwoman Jessica Rosenworcel said in a press release Friday. “These new rules are an important part of our ongoing actions to protect the American people from national security threats involving telecommunications.”

The announcement Friday escalates the FCC's restrictions on the Chinese tech giants, which most recently saw their ability to work with U.S. companies majorly restricted by a 2019 executive order under then-President Donald Trump.

Huawei and ZTE are two of the largest telecommunication companies globally but have come under intense examination by Western countries, such as the United States and the United Kingdom, because of ties to the Chinese Communist Party .

Killexams : US bans sale of Chinese tech from Huawei and ZTE due to ‘unacceptable’ national security risk

The US has outlawed the sale of Chinese-origin communications equipment made by Huawei and ZTE, prohibiting the use of some China-made surveillance systems due to an “unacceptable risk” to national security, in a fresh set of restrictions imposed on Beijing on Friday.

The Federal Communications Commission confirmed the move and said that its five-member panel voted unanimously to adopt new rules which will block the import or sale of certain technology products that threaten Washington’s critical infrastructure.

“The FCC is committed to protecting our national security by ensuring that untrustworthy communications equipment is not authorised for use within our borders, and we are continuing that work here,” said FCC chair Jessica Rosenworcel in a prepared statement.

U.S. authorities announced a ban Friday on the import or sale of communications equipment deemed "an unacceptable risk to national security" -- including gear from Chinese giants Huawei Technologies and ZTE.

Both firms have been on a roster of companies listed as a threat by the Federal Communications Commission (FCC), and the new rules bar future authorizations of their equipment.

The move is the latest in a series of actions to limit the access of Chinese telecom firms to U.S. networks, and comes during a long-running standoff between the world's two biggest economies.

U.S. officials have shown growing wariness in accurate years of Chinese telecommunications companies and technology.

"The FCC is committed to protecting our national security by ensuring that untrustworthy communications equipment is not authorized for use within our borders," said chairwoman Jessica Rosenworcel in a statement.

She added that the new rules are a part of ongoing work to guard against security threats.

A Huawei spokesperson offered no comment on the ban when contacted by AFP.

The order also affects other companies, including video surveillance equipment firms Hangzhou Hikvision and Dahua Technology.

The FCC said Friday that it was also seeking comment on future action relating to existing authorizations.

Previously, Washington had banned Huawei from supplying U.S. government systems and strongly discouraged the use of its equipment in the private sector, with fears that Huawei equipment could be compromised by Chinese intelligence.

In 2019, it put Huawei on a trade blacklist that barred U.S. suppliers from doing business with it, cutting off the Chinese firm -- also a top smartphone brand -- from Google's Android mobile operating system.

The United States has cited national security fears as well to restrict the operations of China's big three state-owned mobile carriers.
