Security company Symantec raised its severity rating of the latest incarnation of the NetSky worm.
The second version of a two-day-old virus, NetSky, has started spreading more successfully than its parent, antivirus researchers said on Wednesday.
Antivirus companies are warning of a new virus that attacks Web sites run by the Chechen rebels and also mocks the authors of MyDoom and Bagle.
Virus writers are turning to new tricks as the trend of big-hitting worms eases off in favour of malware that can slip in under the radar
Microsoft confirmed on Monday that German authorities had arrested a man suspected of writing and releasing a program widely used to surreptitiously control computers on the Internet.
Netsky-P tops the list of the worst virus outbreaks in 2004--a year marked with nearly a 52 percent increase in new viruses, according to a report released Wednesday by security software maker Sophos.
The author of the latest variant of the Bagle worm has gone beyond penning just a piece of code: The writer has also included a poem in the document attachment on which the worm piggybacks.
A new version of the Sasser worm has appeared after the arrest of a teenager suspected of writing the original - but it will not be much of a threat to users who have already patched their systems.
There's a 50 percent chance your unprotected Windows PC will be compromised within 12 minutes of going online, says security vendor Sophos.
Who knows what the authors of Netsky and Sasser are thinking. Robert Vamosi offers some speculation based on messages left inside recent viruses by the authors themselves.
Virus writers have resurrected the Sober worm with a new variant that is spreading quickly over the Internet, according to security experts on Tuesday afternoon.
Virus writers seem to be trying every trick they can these days to infect our computers, but we can fight back. How? For starters, says Robert, try updating Windows frequently.
It is not only the staff at RMIT Labs who have been busy, virus writers worked hard too.
Antivirus companies discovered a fifth version of the Sasser variant this weekend, within hours of German police arresting an 18-year-old man who confessed to being the Sasser worm's author.
Microsoft's US$5 million fund for rewarding informants for leads on virus attacks has snagged its first success with the arrest of a man in Germany who has confessed to the release of the Sasser worm, the software giant said Saturday.
