Black Hat presenters [Robert “RSnake” Hansen], CEO of SecTheory, and [Tom Stracener], security analyst at Cenzic, criticized Google in their presentation “Xploiting Google Gadgets”. [Hansen] and [Stracener] say that there’s currently no way for Google to confirm whether Google Gadget creations contain malicious content or not; this leaves the application vulnerable to a wide range of hacking ugliness such as data poisoning, worms, and theft of data. [Hansen] himself isn’t exactly on the friendliest terms with Google. He’s got a bit of a contentious history and he claims that Google has threatened legal action against him. Nevertheless, if what was presented is true and accurate, then Google has a huge security issue that needs to be addressed sooner rather than later. Google has not yet commented on the situation.
The first night of Black Hat briefings concluded with the Pwnie Award Ceremony. The awards reward achievements in security… but mostly failures. Notably, this was the first year anyone accepted an award in person. Hack a Day took home an early victory by producing a MacBook mini-DVI to VGA adapter (pictured above). The ceremony was fairly straight forward after that. Best Server-Side Bug went to the Windows IGMP kernel vulnerability. It was a remote kernel code execution exploit in the default Windows firewall. The Best Client-Side Bug went to Multiple URL protocol handling flaws like this URI exploit. Mass 0wnage went to WordPress for many many vulnerabilities. Most Innovative Research went to the Cold Boot Attack team. Lamest Vendor Response was won by McAfee for saying XSS can’t be used to hack a server. The Most Overhyped Bug went to [Dan Kaminsky] for his DNS vulnerability. Most Epic FAIL was won by the team behind Debian for shipping the OpenSSL bug for two solid years. Lifetime Achievement Award was won by [Tim Newsham]. Finally, the Best Song was by Kaspersky Labs for Packin’ The K!, which you can find embedded below.
FasTrak is the electronic toll collection system used by the state of California. Motorists can purchase a toll transponder for ~$26 and link the serial number with a debit account to have their tolls deducted automatically. Today at Black Hat in Las Vegas, security researcher [Nate Lawson] presented not just the privacy problems with FasTrak, but why absolutely no transaction from the tag should be trusted.
[Dan Kaminsky]’s much anticipated talk on his DNS findings finally happened at Black Hat 2008 in Las Vegas today. [Dan] has already uploaded the complete slides from his talk as well as posted a short summary to his site. New information in the slides since our previous coverage includes “Forgot My Password” attacks and new attacks on internal network vulnerabilities as a side of effect of DNS cache poisoning. [Dan]’s talk today was over capacity; our shot of the conference room overflow is shown above.
The EFF has just announce the creation of the Coders’ Rights Project website at the Black Hat conference. The sites’ main goal is to centralize legal information for coders, and to help protect important security work from legal actions that may be taken against them with the DMCA and other legal black holes. While this is in no way a fully comprehensive list of everything you need to know, it looks like a good place to start, and provides a few FAQs for suggestions on how to stay in the legal clear as much as possible. At numerous points the documents suggest you speak with a lawyer, if you have any deeper questions, which you absolutely should. This can be very helpful if a person or group finds a security risk, and wants to publish it, or just wants to start looking into possible security risks.
[pdp] provides some perspective on the news regarding the GIFAR attack developed by researchers at NGS Software. As he explains, the idea behind the attack, which basically relies on combining a JAR with other files is not new. Combining JAR/ZIP files with GIF/JPG files will create hybrid files with headers at both the top and bottom of the file and allow them to bypass any image manipulation library as valid files. While tightened security and more stringent file validation practices are advisable, the problem is larger than just a vulnerability in browser security. ZIP is an incredibly generic packing technology used everywhere, from Microsoft files to Open Office documents, and of course, in JAR files. He closes with, “any file format that is based on ZIP, you allow your users to upload on your server, can be used in an attack”
