The data was likely being made available online to the highest bidder.
The compromised data was probably gathered using crimeware toolkits, trojans and command-and-control systems used to drive traffic to the servers.
The servers were discovered by Finjan's Malicious Code Research Center. According to Yuval Ben-Itzhak, chief technology officer for Finjan, the servers were the drop sites for data from malware loaded onto PCs all over the world.
“It was obvious that this was an amateur operation, because the servers had not been hidden in any way," he said. "It was probably someone using off-the-shelf crimeware packages that professional hackers are selling to amateurs."
The typical amateur can buy a complete suite of crimeware for US$200, and can commit internet crimes without having any sophisticated computer skills, Ben-Itzhak said.
According to a report published by Finjan, the stolen data included:
- Compromised medical related data of hospitals and publicly owned healthcare providers
- Compromised business related data of a U.S. airline carrier
- Personal identity information
Two days after being reported to local and international law enforcement authorities, the servers went down, but the individuals behind the operation have not been caught.
Said Ben-Itzhak, “It's hard to find the perpetrators, because a server could be located in Argentina, the criminals could be in Eastern Europe, and the crime committed in the U.S.”
How can this kind of activity be guarded against? The basic guidelines apply: Stay current with patches and anti-virus updates, use firewalls and consider adding another layer of security ahead of browsers to stop malware from installing itself –- or run PCs under credentials that prevent software installation, he said.
“Although we are just reporting on two servers,” Ben-Itzahak said, “I'm sure that there are hundreds if not thousands of servers like these that are not so easily detected. I'm sure that many companies are not even aware that their data may be in the wrongs hands right now.”
