Sophos, a world leader in protecting businesses against viruses, spyware and spam, has reported its latest report on the top spam relaying countries. The United States remains perched atop the list of the chart and is the source of 23.2 % of the world’ spam.
But, researchers at Sophos revealed, that the United States, for the first time in that period, could not lower the volume of spam it brought about during the first quarter. The closest competitors of US are China and South Korea, though both of the countries have managed to reduce their statistics since Q1 2006.
Researchers said,
the vast majority of spam is still being relayed by so-called zombie networks, or botnets, which are PCs that have been hijacked by Trojan horse threats, worms and other viruses, so as to be used to secretly distribute infected e-mail.
Asia has topped by 40 per cent of all spam mails. Sophos has disclosed that more than 75 per cent of all phishing emails are aimed at users of PayPal or eBay. There have been drastic upsurges in Spam containing embedded images from 18.2 % in January to 35.9 % in June. By using images, rather than text, messages can evade finding by a few anti-spam filters that depends upon the analysis of textual spam content.
