Saturday, March 6th, 2010

Spanish law-enforcement agencies have recently shut down a 12M PC botnet, codenamed Mariposa (spanish for “butterfly”), distributed in more than 190 countries.

Zeus botnet’s C&C through Amazon EC2

Thursday, December 17th, 2009

A variant of the Zeus bot (Zbot) was found using Amazon’s Elastic Computer Cloud (EC2) infrastructure for Command&Control commands to infected machines.

Zbot is a password-stealing software, logs financial data and sends them to the botnet. Last year more than 100M US fraud was linked with Zeus malware variants. It was also held responsible for the “destruction” of 100.000 infected computers by deleting registry key data, making them inoperable. Zeus botnet is estimated to consist of millions of infected computers around the world.

Shodan, a tool or a threat?

Thursday, December 17th, 2009

Last month a new search engine appeared, called Shodan. It is a  Computer Search Engine, available for free in public, allowing search for routers, servers, computers or any device that opens a port. It is based on a simple idea: Port scan, grab headers and index the results. Quoting Shodan’s quick guide, “SHODAN lets you find servers/ routers/ etc. by using the simple search bar up above. Most of the data in the index covers web servers at the moment, but there is some data on FTP, Telnet and SSH services as well. Let me know which services interest you the most and I’ll prioritize them in my scanning”.

A typo can get you infected

Thursday, December 10th, 2009

According to McAfee and their third annual “Mapping the Mal Web” report, more than a third of Cameroon domains (TLD of .cm) are infested with viruses or other types of malicious software (malware) and scams. Given that it’s very easy to mis-type .com as .cm, this presents as an opportunity to attackers and a headache for Internet users. Second place on the most-infested domains list goes to China (.cn), while Hong Kong (last year’s ‘winner’) is now far from the top.
