- Several new blog posts have been published this week, including:
Stories
- Token Kidnapping Still Alive - Token kidnapping allows for privilege escalation on Windows platforms, and word is that this vulnerability still has no fixes and ways to bypass existing protections will be released at this year's BlackHat security conference. I find this interesting because each month, Microsoft puts language in several of their security bulletins that downplays vulnerabilities that do not automatically lead to Administrator or SYSTEM privileges.
- New Microsoft Windows LNK vulnerability - This one is a bit scary for a lot of reasons. All versions of Windows are vulnerable to an attack when loading LNK (shortcut files) in Windows Explorer. This means USB drives, CDs/DVDs, or SMB shares could contain an exploit that only need the user to view the file in Explorer (not even open it, just view the icons). Tenable has released a couple of related plugins:
- Windows Shell Shortcut Icon Parsing Arbitrary Code Execution (2286198) - This plugin detects the LNK vulnerability by using credentials and looking in the registry for the registry value that disables the displaying of icons for shortcut files (.LNK).
- Siemens SIMATIC WinCC Default Password Security Bypass Vulnerability - Detects the default password vulnerability that was being exploited by the malware using the LNK vulnerability.
- Physical Security — Some Quick Observations - Simple techniques are often used to bypass physical security. This article outlines how tools can be used to bypass interior doors, motion sensors and door alarms. I'd really like to see more research in the area of tying in physical security into your security event management systems. Of course, cameras are a good option to see when someone bypasses a door or sensor, but those can be subverted as well (especially the wireless camera systems that use 2.4 GHz wireless frequencies).
- Mozilla Ups Security Bounty from $500 to $3,000 - This is an interesting move by Mozilla; finding a bug now could pay you $3,000. I think we're going to see more of this as the black market could yield the highest payment for a vulnerability, especially in a popular product such as Firefox.
- Blackhat/BSides/Defcon Talks - Chris's Picks - Are you attending these upcoming conferences? It seems there are more talks than ever! Other than attending Tenable's party, visiting our booth and going to some of our researcher's talks at DEF CON, Chris has a great list!
- PE-Scrambler Is Now Open-source - This is a great tool used to obfuscate binaries, it can be used to prevent disassembly and evade antivirus programs.
