Malware increasingly uses peer-to-peer communications, researchers say

Lucian Constantin | June 6, 2013
The number of malware samples that use P-to-P (peer-to-peer) communications has increased five-fold during the past 12 months, according to researchers from security firm Damballa.

Researchers from the Institute for Internet Security in Germany, VU University in Amsterdam and security providers Dell SecureWorks and Crowdstrike recently published a report on the resilience of peer-to-peer botnets.

"Our evaluation has shown weaknesses which could be used to disrupt the Kelihos and ZeroAccess botnets," they said in their report. "However, we have also shown that the Zeus and Sality botnets are highly resilient to sinkholing attacks, the currently most used class of disruptive attacks against P2P botnets."

The researchers concluded that finding alternative mitigation methods against P-to-P botnets is "urgently needed."
