Brazil almost equals the US as the two main sources of the world’s spam, according to analysis of Internet threats in June by managed security firm, Network Box. The US is comfortably back up at the top of the virus charts, though, producing more than 21 (21.3) per cent of viruses (up from 17.2 per cent in May).

Korea is still responsible for the highest number of intrusion attacks, with one in four (25. 1 per cent) of all intrusions originating from the country.

On a positive note, the proportion of phishing attacks has reduced dramatically from last month, to just over four per cent of all viruses (down from 20.3 per cent in May). However, Trojans are on the rise again, leaping to 27.23 percent from last months 3.7 per cent of malware.

Simon Heron, Internet Security Analyst for Network Box says: “We have seen a significant increase in the number of Trojans in June, with a spike at the end of the month as malware writers used the deaths of Farah Fawcett and Michael Jackson to send emails that would infect users’ computers.”
