The increase was marked at 4.07 and 6.25 per cent respectively, pushing these sites to third and fourth places in the list of those attacked most, however PayPal and eBay held the unenviable distinction of attracting most attention from phishers in the last month.

In the following months, the experts at Kaspersky Lab predict a surge in spam linked to Google+ after signs that spammers have begun exploiting the growing interest in the new social network: We expect an increase in unsolicited emails exploiting the new Google social network. They will most likely contain both phishing links and malicious code, says Maria Namestnikova, Senior Spam Analyst at Kaspersky Lab.
June also saw the fight against spammers continue. Microsoft, which managed to block the Rustock botnet together with US law enforcement agencies, is keeping the pressure on cybercriminals. A recent Microsoft blog stated that the company intended to initiate a legal case against the Russian citizens suspected of creating and maintaining Rustock, even going as far to say that a criminal case could be brought in the framework of the Russian legal system.
The Russian legal theme continued with the arrest of Pavel Vrublevsky, the owner of the international online payment service ChronoPay, in June at Moscows Sheremetyevo airport. He was charged with organising DDoS attacks against a competitor. The arrest was in no way attributed to his spamming activity Vrublevsky is believed to be the founder of the large pharmaceutical affiliate program Rx-promotion.

As of June, the creation, distribution, purchase and storage of malicious programs, as well as the distribution of pornographic spam, is a criminal offence in the country. India remained the most popular source of spam in June. Brazil returned to second place with an increase of 4.4 per cent compared to May. The most noteworthy changes saw South Korea fall from second to fourth in the rating that tracks where spam originates, while Russia dropped two places to seventh.
There was a slight decrease in the amount of malware blocked in mail traffic in June. Malicious files were found in 3.8 per cent of all emails, a decrease of 0.3 per cent compared with the previous month. There were no major changes to the Top 10 countries where mail antivirus detected malware most frequently. Italy moved up from sixth to fourth place following an increase of 1.5 per cent. Trojan-Spy.HTML.Fraud.gen still occupied first place among the Top 10 malicious programs distributed via mail traffic.
Statistics show that almost a third of all English-language spam was fraudulent and was either sent with the intention of extorting money from users or contained a malicious attachment or link to malicious code. Pharmaceutical spam was the second most popular category. Offers of quick earnings and dubious personal loans, various goods and services along with fake designer goods were among the other most prominent categories of spam in June.
