Show Notes:

Sophos anti-virus detects it self

  • Earlier this week Sophos released a scheduled update to their anti-virus definition files
  • The new definitions detected the Sophos updating process, and a number of other auto-updating applications, as variants of the malware Shh/Updater-B
  • In addition to setting of a huge volume of false positives, the detection also resulted in the quarantine, blocking or deletion of parts of the Sophos updater
  • The updated definitions that solve the problem were released on Wed, 19 Sep 2012 21:32 BST
  • However, the updated definitions could not be downloaded by Sophos, because the updater had been broken
  • This is an especially large issue for enterprise deployments of Sophos
  • The Sophos support number was down, the call volume was so great that most people could not even get into the hold queue

0-day Flaw in Internet Explorer active in the wild

  • Internet Explorer versions 6 through 9 are vulnerable to a new series of attacks
  • Exploits for a previously unknown use-after-free memory corruption vulnerability, in addition to three more exploits that were found and tied to a hacker group in China known as Nitro (the same group responsible for exploits of two zero-day Java flaws disclosed three weeks ago)
  • Security researcher Eric Romang discovered the first of the exploits last weekend while monitoring an infected server
  • When a user lands on an infected page, the exploit installs the PoisonIvy remote access Trojan
  • Jaime Blasco of AlienVault Labs then discovered three additional exploits, one of which drops the PlugX trojan
  • The new exploits appear to be targeted at defense contractors in the U.S. and India
  • An unknown exploit was found in a Defense News Portal site in India, it had been served for at least four days
  • Microsoft is slated to release a patch on Friday , until then, a ‘fixit’ patch is available
  • A new metasploit module to test for and exploit the vulnerability has been released
  • Additional Coverage

The “top secret” room where 260 Internet Service Providers connect

  • Nearly every carrier neutral data center in the world contains a MeetMe room
  • MeetMe rooms more often used for private peering, rather than internet transit
  • Transit is when you buy ‘Internet’ service from another provider, they provide you with a ‘default route’ that you can send traffic to, and it will be delivered to anywhere on the internet
  • Peering is where providers swap traffic that is specifically destin to each others networks, so if Provider A peers with Provider B, Provider A must use their transit connection to reach provider C, only traffic between A and B (and their customers) are allowed across the ‘peering’ link
  • If 1 Wilshire (the building in question) were to go entirely offline, all connections in and out severed, the Internet would continue to operate, traffic would be routed around the missing nodes
  • Performance would be degraded, and it is possible that some of the ‘backup’ routes could not handle all of the traffic, but the network would not cease to work
  • The Internet is based on the principle of being able to get data from Point A to any Point B, reliably
  • To do this, the Internet’s backbone providers use BGP4 routing protocol (Border Gateway Protocol)
  • Most Internet Transit providers have maps that look like this:
  • nLayer
  • Hurricane Electric
  • Abovenet (Zayo)
  • Level3
  • NTT
  • Vocus (Australian)
  • As you can see on most all of these maps, there are almost always multiple paths that a packet can take to get from point A to point B
