Last week's news about evidence of LastPass vault decryption targeting cryptocurrency keys, and the UK's backing down on its encryption monitoring legislation. How hardware security modules (HSMs) allow cryptographic operations like code signing without exposing private keys. Browser identity segregation using multiple profiles rather than separate browsers. Requirements and best practices for securely wiping data from modern solid state drives. A countdown clock for the 32-bit UNIX time rollover in the year 2038. Steve's plan to move off Twitter and onto email lists for Security Now communication. A deep dive into cryptographic hash collisions, using fewer hash bits, and balancing anonymity with statistical meaning.

Steve provides an update on ValiDrive, his new freeware utility for testing USB drives. It identifies bogus mass storage drives and performance differences between drives. There has been another sighting of Google's Topics API, this time on Android phones. It allows apps to get information about users' interests based on recent app usage. Apple has opened up their iPhones to security researchers through their Security Research Device program since 2019. Researchers get access to customize kernels, entitlements, and other low-level features without compromising security. Research reveals vulnerabilities in browser extensions that allow them to steal plaintext passwords from a website's HTML source code. Even sites like Google, Facebook, Amazon, IRS, and Capital One are affected. Feedback from listeners on topics like Apple's stance on scanning iCloud data for CSAM, Microsoft's broken TLS timestamp implementation, using VirusTotal to check downloaded files, ReadSpeed limitations, and downloading malware for VirusTotal checks. Apple publicly shares a letter from a CSAM activist demanding they implement scanning to detect child abuse images in iCloud Photos. Apple responds clearly stating they will not compromise user privacy and security to do so.

Picture of the Week: Steve shares a funny "what we say vs what we mean" image about tech support conversations. WinRAR v6.23 fixes: Steve explains that updating to the latest WinRAR is more important than initially thought, with two critical vulnerabilities being actively exploited by hackers since April to install malware. HTTPS for local networks: Responding to listener email, Steve agrees HTTP is fine for local network devices like routers but notes risks in larger corporate networks. Portable domains for email: Steve endorses a listener suggestion to purchase your own domain and use third-party services, retaining control if a provider shuts down. Google Topics and monopolies: Steve and Leo debate whether Topics favors large advertisers with greater reach to get user targeting data. Voyager 2 antenna analysis: A listener calculates the antenna beam width mathematically, showing 2 degrees off-axis may not be as remarkable as it sounded. Windows time settings: Steve clarifies the STS issue does not impact end users changing Windows clock settings, it's enterprise server-side. Unix time in TLS handshakes: The hosts discuss why Unix time stamps are sent but not required for TLS, tracing back to early nonce generation. Fake flash drives: Steve warns of a slew of fake high-capacity thumb drives flooding the market, explaining how SpinRite tests detected the flaw. Man-in-the-middle attacks: While agreeing HTTPS helps prevent malicious injection, Steve examines MITM attack practicality, arguing they are difficult for hackers to pull off.
