Kaminsky's DNS Attack Disclosed, Then Pulled
An anonymous reader writes "Reverse engineering expert Halver Flake has recently mused on Dan Kaminsky's DNS vulnerability. Apparently his musings were close enough to the mark to cause one of the Matasano team, who apparently already knew of the attack, to publish the details on the Matasano blog in a post entitled 'Reliable DNS Forgery in 2008.' The blog post has since been pulled, but evidence of it exists on Google and elsewhere. It appears only a matter of time now before the full details leak." Reader Time out contributes a link to coverage on ZDNet as well. -

The Internationalization of Malware
Ant brings us a write-up from a former malware analyst about the difficulties in fighting malware as it expands beyond English-language targets and into societies with different standards for privacy and security. Quoting: "One of the most fascinating facets of the increasing internationalization of malware is the cultural assumptions around such software. What is considered malware in the US may be commonly accepted in China or Japan, and this is largely due to the society that it exists in. Anti-cheating rootkits are very common in games released in these countries. What is considered to be invasive in the North American or European world is acceptable there. These anti-cheating rootkits would hook into the kernel space in a very invasive way, and have the behavioral characteristics of malware such as hooking into the keyboard driver. This made it very difficult from a purely technical standpoint to distinguish them." -
Multiple Security Holes In Ruby 1.8, 1.9
ruphus13 notes a six-pack of serious vulnerabilities discovered in Ruby by a member of Apple's security team, Drew Yao. Patches are linked from the ruby-lang.org advisory. "With the following vulnerabilities, an attacker can lead to denial of service condition or execute arbitrary code... These vulnerabilities are likely to crop up in just about any average ruby web application. And by 'crop up' I mean 'crop up exploitable from trivial user-specified parameters.' It's not hard to begin imagining cases where Ruby/Rails programmers use code similar to the samples above to routinely handle user input." -
NULL Pointer Exploit Excites Researchers
Da Massive writes "Mark Dowd's paper "Application-Specific Attacks: Leveraging the ActionScript Virtual Machine" has alarmed researchers. It points out techniques that promise to open up a class of exploits and vulnerability research previously thought to be prohibitively difficult. Already, the small but growing group of Information Security experts who have had the chance to read and digest the contents of the paper are expressing an excited concern depending on how they are interpreting it. While the Flash vulnerability described in the paper[PDF] has been patched by Adobe, the presentation of a reliable exploit for NULL pointer dereferencing has the researchers who have read the paper fascinated. Thomas Ptacek has an explanation of Dowd's work, and Nathan McFeters at ZDNet is 'stunned by the technical details.'" -
Interview with IE Lead Program Manager
crackman writes "Matasano Security is running an excellent interview with Christopher Vaughan, a lead PM on the IE team. Christopher has worked on every release of Internet Explorer since version 2. He discusses IE7, security lessons learned from IE6, the future of .NET managed code in IE, and more."
