As if there weren’t enough worrying global news stories already, today the British press and media have been full of a story involving the public WiFi networks at some major railway stations. Instead of being faced with the usual don’t-be-naughty terms and conditions page, commuters were instead faced with a page that definitely shouldn’t have […]
Open Source has sort of eaten everything in software these days. And that includes malware, apparently, with open source Command and Control (C2) frameworks like Sliver and Havoc gaining traction. And of course, this oddball intersection of Open Source and security has intrigued at least one security researcher who has found some interesting vulnerabilities. Before […]
It’s time to talk about Microsoft’s patch Tuesday, and the odd vulnerability rollback that happened. CVE-2024-43491 has caught some attention, as it’s a 9.8 on the CVSS scale, is under active exploitation, and results in Remote Code Execution (RCE). Yikes, it sounds terrible! First off, what actually happened? The official statement is that “build version […]
[Thomas Roche] of NinjaLab is out with EUCLEAK, (pdf) a physical attack against Infineon security microcontrollers, and the security tokens that contain them. The name is a portmanteau of Euclidean and leak. And no surprise, it’s a data leak in some implementations of the Extended Euclidean Algorithm (EEA), a component of an Elliptical Curve Digital […]
We finally have some answers about the Windows IPv6 vulnerability — and a Proof of Concept! The patch was a single change in the Windows TCP/IP driver’s Ipv6pProcessOptions(), now calling IppSendError() instead of IppSendErrorList(). That’s not very helpful on its own, which is why [Marcus Hutchins]’s analysis is so helpful here. And it’s not an […]
There have been some hilarious issues on mobile devices over the years. The HTC Dream had a hidden shell that was discovered when a phone rebooted after sending a text containing just the word “reboot”. iOS has gotten in on the fun from time to time, and this time it’s ""::. Type the double quotes, […]
You may have heard about a very large data breach, exposing the Social Security numbers of three billion individuals. Now hang on. Social Security numbers are a particularly American data point, and last time we checked there were quite a few Americans shy of even a half of a billion’s worth. As [Troy Hunt] points […]
The Raspberry Pi Foundation had their new RP2350 chip audited by Hextree.io, and now, both companies want to see if you can hack it. Just to prove that they’re serious, they’re putting out a $10,000 bounty. Can you get inside? The challenge to hack the chip is simple enough. You need to dump a secret […]
You may have heard some scary news about RISC-V CPUs. There’s good news, and bad news, and the whole thing is a bit of a cautionary tale. GhostWrite is a devastating vulnerability in a pair of T-Head XuanTie RISC-V CPUs. There are also unexploitable crashes in another T-Head CPU and the QEMU soft core implementation. […]
It’s a bit of bitter irony, when a security product gets used maliciously, to pull off the exact attack it was designed to prevent. Enter Proofpoint, and the EchoSpoofing attack. Proofpoint offers an email security product, filtering spam and malicious incoming emails, and also handling SPF, DKIM, and DMARC headers on outgoing email. How does […]
