UK spamming attacks have quadrupled in frequency since the start of 2008, according to an anti-spam software company.


ClearMyMail says its results for Q2 2008 show that the average amount of spam blocked for each customer during those three months was up to 30,846 – almost four times as much as the figure for Q1 (8,156).


A breakdown of the figures, provided by ClearMyMail, showed that Royal Bank of Scotland was the main company to be targeted in phishing attacks. The bank had previously only been named in 0.02 per cent of the total proportion of phishing emails blocked and didn't even make the top 10 for Q1 2008. But this rose to a staggering 42.78 per cent in the Q2 figures.


The top 10 UK financial organisations targeted by spammers are: 1: Royal Bank of Scotland (42.78 per cent of all phishing attacks blocked); 2: Abbey (18.28 per cent); 3: Halifax (9.77 per cent); 4: Natwest (7.06 per cent); 5: PayPal (6.79 per cent); 6: Citi card/bank (4.75 per cent); 7: Lloyds TSB (4.70 per cent); 8: HSBC (3.36 per cent); 9: Nationwide (0.93 per cent) and, 10: Barclays (0.82 per cent).


Also, the firm said that customers who use Orange as their ISP receive the highest percentage of spam. During Q1, 96 per cent of all emails sent to Orange ISP accounts were spam, which rose to 96.93 per cent in Q2. The so-called ‘most spammed man in Britain', Colin Wells, had an average of 44,000 spam mails blocked from his Orange ISP email inbox - daily - by ClearMyMail.


The findings also showed that the UK and US are responsible for sending the most spam to UK accounts, with the UK most culpable, sending 19.65 per cent of spam.  However, the amount of spam reaching the UK from the US has dropped from 19.53 per cent in Q1 to 12.57 per cent.


Dan Field, managing director of ClearMyMail, said: “These statistics are becoming increasingly worrying and for the average amount of spam blocked per person to have nearly quadrupled in the last three months suggests that action desperately needs to be taken.”
