– ’Police Virus’ still rampant despite the arrest of the cyber-criminals allegedly responsible for the attacks
– The number of infections has doubled since the arrest of the cyber-gang leader in Dubai
Despite the arrest of the cyber-criminals allegedly responsible for the ‘Police Virus’ ransomware attacks, the infamous piece of malware has continued to infect thousands of computers around the world, according to data gathered by PandaLabs, the anti-malware laboratory of Panda Security, from December 2012 to February 2013.
The arrest of the cyber-gang leader in Dubai, in an international operation led by the Technological Investigation Brigade of Spain’s National Police force and coordinated by Europol and Interpol, has not put an end to the malware epidemic.
“This ransomware was netting its creators profits in excess of €1 million per year,” explained Luis Corrons, technical director of PandaLabs. “However, the number of infections keeps growing, which leads us to think that we are facing an unspecified number of groups launching the same kind of attacks.”
The ‘Police Virus’ Is Still Active
This malware epidemic has continued to infect hundreds of thousands of computers around the world, using fear and blackmailing techniques to extort money from computer users. The scam is very lucrative and has evolved over time, using various techniques to trick users. The most recent evolution even shows images taken with the user’s webcam, making the scam all the more realistic.
In fact, research carried out by PandaLabs on two of the malware families used in the attacks has revealed that the number of infections has doubled from 2,500 to more than 5,000 since the arrest of the ringleader in December 2012 until February 2013.
The vast majority of these infections are caused by ”exploit kits”, applications that allow attackers to infect users’ computers simply by getting them to visit a compromised Web page. Cyber-criminals take advantage of security flaws in popular programs –such as Adobe Acrobat or Java, for example– to gain control of systems. At present, there are still a lot of variants of the Police Virus in circulation, all of them detected by PandaLabs as Trj/Ransom.AB.
PandaLabs offers users a series of tips to avoid falling victim to this type of scam: Keep your computer’s software (including the operating system and all installed programs) up-to-date; disable Java in your Web browser, or uninstall it completely if you don’t need it.
Panda Security, The Cloud Security Company, has launched a new version of its free antivirus software Panda Cloud Antivirus that neutralizes malware that takes advantage of any of the vulnerabilities exploited by the Police Virus, even of those that have not yet been identified.
