The latest version of the Qakbot worm, which targets financial websites, appears to be spreading more rapidly than before.
According to a recent report by an internet security company, between early April and early May, the number of Qakbot infected computers malware increased to more than 200,000, reaching 20,000 or more on certain days. Vikram Thakur, principal security response manager for the security company, stated that activity from Qakbot rarely exceeds 50,000 compromised machines.
"This is definitely something to watch out for, considering it has been under development and it has been continuously evolving over the past few years," said Thakur. "This threat is a major problem for corporations because of just the way it actually spreads within an environment."
If installed on a computer, the malware steals banking credentials and files, with cyber criminals on the other end injecting online transactions into banking sessions, stealing money from a person’s account.
In April, the amount of malware produced reached 73,000 on a daily basis, increasing 26 percent from April 2010, according to a report by an internet security company.
