The Washington Post has published a long story on the unlocking of the San Bernardino Terrorist’s iPhone 5C in 2016. We all thought it was an Israeli company called Cellebrite. It was actually an Australian company called Azimuth Security. Azimuth specialized in finding significant vulnerabilities. Dowd, a former IBM X-Force researcher whom one peer called … Read More “Details on the Unlocking of the San Bernardino Terrorist’s iPhone” »
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” »
Check Point has evidence that (probably government affiliated) Chinese hackers stole and cloned an NSA Windows hacking tool years before (probably government affiliated) Russian hackers stole and then published the same tool. Here’s the timeline: The timeline basically seems to be, according to Check Point: 2013: NSA’s Equation Group developed a set of exploits including … Read More “Chinese Hackers Stole an NSA Windows Exploit in 2014” »
At the virtual Enigma Conference, Google’s Project Zero’s Maggie Stone gave a talk about zero-day exploits in the wild. In it, she talked about how often vendors fix vulnerabilities only to have the attackers tweak their exploits to work again. From a MIT Technology Review article: Soon after they were spotted, the researchers saw one … Read More “On Vulnerability-Adjacent Vulnerabilities” »
This is a weird story: Hernandez was able to evade capture for so long because he used Tails, a version of Linux designed for users at high risk of surveillance and which routes all inbound and outbound connections through the open-source Tor network to anonymize it. According to Vice, the FBI had tried to hack … Read More “Facebook Helped Develop a Tails Exploit” »
Remember Spectre and Meltdown? Back in early 2018, I wrote: Spectre and Meltdown are pretty catastrophic vulnerabilities, but they only affect the confidentiality of data. Now that they — and the research into the Intel ME vulnerability — have shown researchers where to look, more is coming — and what they’ll find will be worse … Read More “Another Intel Speculative Execution Vulnerability” »
Last year, ZecOps discovered two iPhone zero-day exploits. They will be patched in the next iOS release: Avraham declined to disclose many details about who the targets were, and did not say whether they lost any data as a result of the attacks, but said “we were a bit surprised about who was targeted.” He … Read More “New iPhone Zero-Day Discovered” »
Yesterday’s Microsoft Windows patches included a fix for a critical vulnerability in the system’s crypto library. A spoofing vulnerability exists in the way Windows CryptoAPI (Crypt32.dll) validates Elliptic Curve Cryptography (ECC) certificates. An attacker could exploit the vulnerability by using a spoofed code-signing certificate to sign a malicious executable, making it appear the file was … Read More “Critical Windows Vulnerability Discovered by NSA” »
