NSA Over-surveillance

Here in 2022, we have a newly declassified 2016 Inspector General report—”Misuse of Sigint Systems”—about a 2013 NSA program that resulted in the unauthorized (that is, illegal) targeting of Americans. Given all we learned from Edward Snowden, this feels like…

An Untrustworthy TLS Certificate in Browsers

The major browsers natively trust a whole bunch of certificate authorities, and some of them are really sketchy: Google’s Chrome, Apple’s Safari, nonprofit Firefox and others allow the company, TrustCor Systems, to act as what’s known as a root certificate…

Defeating Phishing-Resistant Multifactor Authentication

CISA is now pushing phishing-resistant multifactor authentication. Roger Grimes has an excellent post reminding everyone that “phishing-resistant” is not “phishing proof,” and that everyone needs to stop pretending otherwise. His list of different attacks is particularly useful. This article has…

Using Wi-FI to See through Walls

This technique measures device response time to determine distance: The scientists tested the exploit by modifying an off-the-shelf drone to create a flying scanning device, the Wi-Peep. The robotic aircraft sends several messages to each device as it flies around,…

Relay Attack against Teslas

Nice work: Radio relay attacks are technically complicated to execute, but conceptually easy to understand: attackers simply extend the range of your existing key using what is essentially a high-tech walkie-talkie. One thief stands near you while you’re in the…

FBI Seizes Stolen Cryptocurrencies

The Wall Street Journal is reporting that the FBI has recovered over $30 million in cryptocurrency stolen by North Korean hackers earlier this year. It’s only a fraction of the $540 million stolen, but it’s something. The Axie Infinity recovery…

Security and Cheap Complexity

I’ve been saying that complexity is the worst enemy of security for a long time now. (Here’s me in 1999.) And it’s been true for a long time. In 2018, Thomas Dullin of Google’s Project Zero talked about “cheap complexity.”…

Man-in-the-Middle Phishing Attack

Here’s a phishing campaign that uses a man-in-the-middle attack to defeat multi-factor authentication: Microsoft observed a campaign that inserted an attacker-controlled proxy site between the account users and the work server they attempted to log into. When the user entered…

Friday Squid Blogging: The Language of the Jumbo Flying Squid

The jumbo flying squid (Dosidicus gigas) uses its color-changing ability as a language: In 2020, however, marine biologists discovered that jumbo flying squid are surprisingly coordinated. Despite their large numbers, the squid rarely bumped into each other or competed for…
