New Versions of Chrome and Firefox Disable DigiNotar Root

Mozilla has released version 6.01 of its Firefox browser, which now removes the compromised DigiNotar root certificate from the list of trusted roots. The move comes just two days after security researchers discovered that the Dutch company had issued a valid wildcard certificate for Google to an unknown third party.

Apache Fixes Range Header DoS Flaw

There is a new version of the Apache Web Server available that fixes the recently disclosed range header denial-of-service vulnerability. Apache 2.2.20 is was released Tuesday and the new content mostly comprises the bug fix.


UPDATE: A certificate authority in the Netherlands issued a valid SSL wildcard certificate for Google to a third party in July, leading to concerns that attackers may have been using the certificate to route sensitive traffic through their own servers, capturing it and compromising user data in the process. The certificate was revoked by the CA, DigiNotar, after the problem came to light Monday and Mozilla and Microsoft both have removed DigiNotar from their lists of trusted root CAs.

Despite the media’s love-affair with Anonymous style cyber-anarchy and vigilante-hacktivism, the vast majority of DDoS attacks are carried out by criminals seeking financial gain, not activists, according to a new research report.

Attackers interested in getting the most bang for their buck focus on ubiquitous software. Microsoft’s Office, Adobe’s Acrobat and Oracle’s Java have all become popular platforms exploited by cybercriminals intent on compromising end users’ systems. Another platform has quietly made its way onto many systems and become the focus of security researchers, if not cybercriminals: Webkit.

A new worm called Morto has begun making the rounds on the Internet in the last couple of days, infecting machines via RDP (Remote Desktop Protocol). The worm is generating a large amount of outbound RDP traffic on networks that have infected machines, and Morto is capable of compromising both servers and workstations running Windows.
