Threats continue to rise but phishing down

Network Box : 01 September, 2008  (Technical Article)
Network Box malware survey shows a continuing rise in the levels of threat seen by users but with a significant fall in phishing over the quarter
For the third month running, mass phishing attacks are down, according to the latest threat statistics analysed by managed security company, Network Box. Phishing attacks now make up less 44 per cent of viruses, down from 57 per cent in July and from 69 per cent in June.

But overall, the number of threats hitting businesses has increased by a massive 51 per cent on last month. Network Box reports that it sent out around 120,000 more signatures for new viruses in August, compared to July, with threats at "a critical level", registering four on the company's alert condition scale, where the highest level is five. Overall, the company issued around 30 per cent more 'push updates' to its system in August (equating to around 14 extra per day), compared to the previous month.

There has been a slight lift in viruses and spam sent from China during the Olympics. China ranks in the top five sources (at number five) of viruses this month, accounting for 3.5 per cent of all viruses - a marginal increase on July's 3.3 per cent . It comes in at number three for sources of spam - behind the USA and Turkey - accounting for just over six per cent of all spam sent (up from 5.5 per cent last month).

The USA is still the most prevalent source of spam and viruses, accounting for nearly 27 per cent of all viruses and 17 per cent of all spam sent.

Korea still tops the charts for intrusions, accounting for a massive 30 per cent of all intrusions (up from 26.5 per cent last month). The USA is still in second place, at just under 15 per cent.

The number of viruses sent from the UK has also lifted slightly, accounting for just over five per cent of all viruses sent (up from 4.5 per cent last month).

Simon Heron, Internet Security Analyst at Network Box, comments: "It is interesting to see that the proportion of phishing relative to other malware has been down over the last few months. Unfortunately, it doesn't mean that phishing scams are on the way out, only that other malware has been on the increase. Its been an active summer, with DNS and BGP vulnerabilities revealed, a rash of blogging attacks and Google hacks. In the immortal words of Hill Street Blues: 'lets be careful out there'!."
