Bot nets likely behind jump in spam
A significant rise in the global volume of spam in the past two months has security analysts worried that bot nets are increasingly being used by spammers to stymie network defenses erected to curtail bulk email.
Estimates of the magnitude of the increase in junk email vary, but experts agree that an uncommon surge in spam is occurring. On the low side, Symantec, the owner of SecurityFocus, has found that average spam volume has increased almost 30 percent for its 35,000 clients in the last two months. Others have seen much more significant jumps: Spam black list maintainer Total Quality Management Cubed has seen a 450 percent increase in spam in two months, and the amount of spam filtered out every week by security software maker Sunbelt Software has more than tripled compared to six months ago.
