F-Secure blogged about a new Trojan for Mac’s IOSX

http://www.f-secure.com/weblog/archives/00002206.html
It relies on the fact that due to the "dispute" between Adobe and Apple, Apple's latest Mac OS X version "Lion" comes without any flash player, enhancing the odds people do not find it strange to have to install it separately.

This is a DNS changer type malware that modifies the hosts file to redirect google sites to 91.224.160.26. Which appears to be in the British Virgin Islands.

When I asked that server where google was it gave me an interesting response. It is still providing fake replies to dns queries for google.

> lserver 91.224.160.26
Default server: 91.224.160.26
Address: 91.224.160.26#53
> google.com
Server:         91.224.160.26
Address:        91.224.160.26#53

Name:   google.com
Address: 91.224.160.26

Watching for upd port 53 packets towards that IP might be a good idea.

  UPDATE/CORRECTION:

While the whois information points to the British Virgin Islands a traceroute gave me a very different answer.

Tracing route to 91.224.160.26 over a maximum of 30 hops
