A vulnerability in the Accellion file-transfer program is being used by criminal groups to hack networks worldwide. There’s much in the article about when Accellion knew about the vulnerability, when it alerted its customers, and when it patched its software. The governor of New Zealand’s central bank, Adrian Orr, says Accellion failed to warn it … Read More “Accellion Supply Chain Hack” »
This is a longish video that describes a profitable computer banking scam that’s run out of call centers in places like India. There’s a lot of fluff about glitterbombs and the like, but the details are interesting. The scammers convince the victims to give them remote access to their computers, and then that they’ve mistyped … Read More “Details of a Computer Banking Scam” »

Vice is reporting on a cell phone vulnerability caused by commercial SMS services. One of the things these services permit is text message forwarding. It turns out that with a little bit of anonymous money — in this case, $16 off an anonymous prepaid credit card — and a few lies, you can forward the … Read More “Easy SMS Hijacking” »
Google has demonstrated exploiting the Spectre CPU attack remotely over the web: Today, we’re sharing proof-of-concept (PoC) code that confirms the practicality of Spectre exploits against JavaScript engines. We use Google Chrome to demonstrate our attack, but these issues are not specific to Chrome, and we expect that other modern browsers are similarly vulnerable to … Read More “Exploiting Spectre Over the Internet” »
Security researchers have recently discovered a botnet with a novel defense against takedowns. Normally, authorities can disable a botnet by taking over its command-and-control server. With nowhere to go for instructions, the botnet is rendered useless. But over the years, botnet designers have come up with ways to make this counterattack harder. Now the content-delivery … Read More “Illegal Content and the Blockchain” »
Andrew Appel and Susan Greenhalgh have a blog post on the insecurity of ES&S’s software authentication system: It turns out that ES&S has bugs in their hash-code checker: if the “reference hashcode” is completely missing, then it’ll say “yes, boss, everything is fine” instead of reporting an error. It’s simultaneously shocking and unsurprising that ES&S’s … Read More “On the Insecurity of ES&S Voting Machines’ Hash Code” »
Interesting research: “Who Can Find My Devices? Security and Privacy of Apple’s Crowd-Sourced Bluetooth Location Tracking System“: Abstract: Overnight, Apple has turned its hundreds-of-million-device ecosystem into the world’s largest crowd-sourced location tracking network called offline finding (OF). OF leverages online finder devices to detect the presence of missing offline devices using Bluetooth and report an … Read More “Security Analysis of Apple’s “Find My…” Protocol” »
A good tutorial: But we can go beyond the polarization of electrons and really leverage the electron waviness. By interleaving thin layers of superconducting and normal materials, we can make the quantum electronic equivalents of transistors and diodes such as Superconducting Tunnel Junctions (SJTs) and Superconducting Quantum Interference Devices (affectionately known as SQUIDs). These devices … Read More “Friday Squid Blogging: On SQUIDS” »
Really interesting research: “Exploitation and Sanitization of Hidden Data in PDF Files” Abstract: Organizations publish and share more and more electronic documents like PDF files. Unfortunately, most organizations are unaware that these documents can compromise sensitive information like authors names, details on the information system and architecture. All these information can be exploited easily by … Read More “Metadata Left in Security Agency PDFs” »
