"I've been receiving messages from people I haven't talked to in years via Yahoo Messenger tonight. The message is simply a URL. The URL is
http://yahoo-secretDOTtripodDOTcom"


If your seeing traffic to exploited.lsass.cc you should examine your hosts for a new bot



A few of the handlers are examining a new bot binary.

A bot controller was discovered during this malware analysis.


The bots connect to "exploited.lsass.cc" on port 19899 (TCP).

which currently resolves to:

Name: exploited.lsass.cc

Address: 158.195.101.192

Name: exploited.lsass.cc

Address: 140.123.105.125
DNS resolution is provided by dnsmadeeasy.com

The binary appears to be a version of rbot/sdbot.
