Malware Infection and Distribution Report For June

GFI Software : 07 July, 2011  (Technical Article)
GFI Software highlights phishing attacks on microblogging site and rogue antivirus software among the significant IT security threats seen during June

GFI Software has announced the top 10 most prevalent malware threats for June 2011. Highlights for the month included continued phishing attacks, notably one affecting microblogging site Tumblr, which compromised up to 8,000 user accounts, making it one of the most successful phishing attacks of its kind. Additionally, June saw scammers distributing rogue antivirus software by taking advantage of search traffic related to popular Pokemon video games, as well as luring users to fill out seemingly endless fake questionnaires.


“The Tumblr phishing and spam attacks highlight the importance of building greater awareness about online threats and simple tactics we can all use to defend ourselves,” said Chris Boyd, senior threat researcher at GFI Software. “Some of the attacks we saw in June were aimed at compromising social networking login credentials knowing that many people still use the same username and password for all their online activities, including banking, shopping and email. It is important for users on any social networking site to approach content that looks out of place with care since, as seen on Tumblr, seemingly innocuous attacks can evolve into more serious threats. Also, strengthen your passwords and vary them across all your online accounts to limit your risk and exposure if one is compromised.”


Phishing scams have become increasingly common on social networking sites as scammers have become savvier and bolder in their attacks. In recent months, scammers have used surveys, competitions and the promise of adult content to entice Internet users into divulging their personal information.


GFI also explored the risk of reputation hijacking through legitimate cloud services like Google Docs. The company found a large number of phishing sites using Google Spreadsheets to steal credentials of unsuspecting users.


June also brought some positive news in the fight against online scammers. The US Department of Justice and the FBI announced that they had cracked an international cybercrime ring believed to have scammed more than $72 million (£44.83 million) through scareware sales. As part of Operation Trident Tribunal, the FBI seized computers, servers and bank accounts in a series of raids.


As the summer months continue to roll on, Internet users should be wary of topical threats, which are potential targets for fake antivirus attacks, SEO poisoning and survey scams. These may include the final Harry Potter film and increasing interest in recently announced Republican presidential candidates.
