COLUMBIA, S.C. – Virus and worm threats haven't made headlines as much lately, but one making the rounds on the Internet last week is getting attention. Called Sober.p – or Sober.n or Sober.o – this worm has raised eyebrows by accounting for as much as 70% of all malicious code traffic only a day or so after it was first noticed, according to anti-virus vendors. The worm, which is spreading in English and German versions, spreads by mass mailing copies to addresses it steals from infected computers. More of an annoyance than anything, since it doesn't carry Trojan horses or other malware, it's hidden away in zipped files, which often are not as highly monitored or rejected as other attached files, according to industry experts, and carries subject lines like "Re: Mailing Error" or "Re: Your Email Was Blocked." "Although the numbers for this variant are higher, which may mean it takes a day or two more to die off, I'd be surprised if it was an issue by this weekend," Craig Schmugar, the virus research manager at McAfee, told the TechWeb news service on May 4.
