Mozilla Firefox 6 – Security release for hacked Certificate Authority

QUOTE: Mozilla has released several new versions of programs in order to remove support for a root certificate from a hacked certificate authority.   We reported yesterday about how this root certificate had been used to create a fake certificate, but it turns out that the hack occurred weeks ago and had been used many times. DigiNotar, the hacked certificate authority, is in a desperate struggle to retain their credibility.  The newly-updated programs are:

  • Firefox 6.0.1
  • Firefox Mobile 6.0.1
  • Firefox 3.6.21
  • Thunderbird 6.0.1
  • Thunderbird 3.1.13
  • SeaMonkey 2.3.2

Social Networking Threats – Trend Labs report

QUOTE: KOOBFACE is not the only threat that hounds social media. These social networking sites also have features that can become threat vectors. A seemingly harmless wall post from a friend, a video shared by an online contact, or an instant message from a colleague can potentially lead to an attack.  These features are meant to make socializing effective and meaningful. However, they have also been used by cybercriminals in their attacks. In Facebook, the wall is the riskiest region of the user interface. Cybercriminals have concocted several threats leveraging popular news items

Xpaj Botnet – Complex new file infector

Symantec documents an advanced and highly stealth File Infector that can setup a botnet client on an infected PC

Xpaj Botnet Intercepts up to 87 Million Searches per Year

QUOTE: W32.Xpaj.B is one of the most complex and sophisticated file infectors Symantec has encountered. In an older blog post, Piotr Krysiuk calls it an “upper crust file infector.” He describes several different approaches that the infector uses to increase the difficulty in detecting infected samples. The techniques W32.Xpaj.B uses to conceal itself within an executable are far beyond the norm.

The analysis revealed IP addresses for the command & control (C&C) servers. Infected W32.Xpaj.B executables send a download request to these C&C servers. Analysis of the threat’s backend control infrastructure revealed more than just the data sent from the server to infected clients. The servers contained encrypted binary data, encryption keys, databases, and Web applications. These were all elements of what transpired to be a fraud operation spread over multiple computers hosted in several countries.

Apache Web Server – New DoS Attack Vulnerability

Webmasters should ensure they apply the forthcoming security patch to protect their web server environments:

Apache Web Server – New DoS Attack Vulnerability

QUOTE: Amidst a lack of fanfare this past weekend on a mailing list, a memory exhaustion hack popped up for the Apache webserver that may result in a Denial-of-Service (DoS) style attack. Since the Apache application serves up north of 65% of the websites on the internet, a plausible attack becomes quite an issue, especially if it gets much traction before a patch can be released.

Still, some Apache web servers have been humming along untouched for years without much oversight, and may not receive patches as quickly as the hack spreads, representing a potentially widespread attack surface in the meantime. The posting says “An attack tool is circulating in the wild. Active use of this tools has been observed.” The nice thing is how proactive the Apache Foundation has been since it was brought to their attention.

RSA – How SecurID was compromised

F-Secure documents a recent attack for one of the most secure authentication products, which was quickly corrected to resolve security issues

RSA – How SecurID was compromised

QUOTE: RSA was hacked in March. This was one of the biggest hacks in history. The current theory is that a nation-state wanted to break in to Lockheed-Martin and Northrop-Grumman to steal military secrets. They couldn’t do it, since these companies were using RSA SecurID tokens for network authentication. So, the hackers broke into RSA with a targeted email attack. They planted a backdoor and eventually were able to gain access to SecurID information that enabled them to go back to their original targets and succesfully break into there. In the aftermath of the attack, RSA was forced to replace SecurID tokens for their customers around the world.
