Russian security and anti-virus specialists Kaspersky Labs today released its monthly report on malicious activity, showcasing security trends around the internet.

The report also includes information taken from Kaspersky users, and shows that Kaspersky products blocked some 249 345 057 network attacks during the month of June.

This monumental figure is mirrored in other statistics, showing that around 68 million web-borne infections were prevented, with some 216 million malicious programs detected and neutralised on Kaspersky computers.

And while we usually report worrying trends in the online security sector, the month of June seems to have been an exception. According to the report a number of high profile cybercriminal arrests were made, with two major groups in the US being shut down. The two groups sold fake antivirus software to unsuspecting users, causing an estimated $74 million in damages.

Several law enforcement agencies were also involved in action that saw 600 people being arrested for fraudulent online activities in a number of South East Asian countries. June also saw the arrest of Pavel Vrublevsky, owner of Russia’s largest payment processing centre, ChronoPay, on charges of organising DDoS attacks on a competing service.

It wasn’t all rosy though, as Russian scammers tried to infiltrate BitCoin’s virtual currency system this month, utilising malicious programs to generate the cyber currency in their own accounts. The site’s administration reacted quickly though, and it’s thought that very little money was made from the scam.

The cloud is also looking like an increasingly juicy target for cybercriminals, with hackers utilising Amazon’s cloud service to distribute malware to a number of Brazilian users last month. The malware was designed to steal customer data from nine Brazilian banks, blocking the banks’ security systems and special plug-ins.

Apple users are also facing an increasing onslaught, with a new backdoor for Max OS X (Backdoor.OSX.Olyx.a) being discovered. This allows attackers to gain remote control of an infected machine, spreading and download more malware and acting as part of a botnet.

So while it’s clear that the threat of cybercrime is still looming as largely as ever, it’s good to at least see some progress being made. To check out more detailed info on detected threats by Kaspersky check out the full June 2011 report here.
