Dutch police have arrested three individuals suspected of hacking into more than 100,000 computers worldwide and using the hijacked systems in online crimes.
The recent surge in worms could be part of an underground battle to hijack computers for use in Internet crimes, some security experts say -- but others aren't convinced.
The US remains the world's biggest spammer, according to security firm Sophos, which today released its quarterly report on the world's top spam-offending countries -- dubbed the "Dirty Dozen".
Almost a quarter of the world's spam in the last three months of 2005 was sent from computers in the United States, according to UK antivirus company Sophos.
Spammers have discovered ways of working round protocols that were originally designed to kill spam by allowing e-mail gateways to authenticate the origin of any e-mail. This abuse effectively renders the technologies useless, according to security experts.
It's been nearly six months since President Bush signed the first federal spam law with criminal sanctions--and not one bulk e-mailer has been criminally charged under it so far.
The Australian Communications Authority (ACA) is stepping up its anti-spam campaign by deploying forensic technology allowing it to closely examine e-mails and act against spammers.
On April 12, 1994, a pair of attorneys in Arizona launched a homemade marketing software program that forever changed the Internet.
As Apple's new gadget sells out across the US, spammers are exploiting the situation by sending e-mails that try to dupe recipients into thinking they have won a brand new iPhone of their own.
Almost all of the malware circulating the Internet is written by organised criminals looking for financial gain, experts say, and the problem is set to get worse.
In their quest to retain control over hijacked PCs, cybercriminals will add encryption to their malicious software to avoid detection and removal, one expert predicted Monday in the United States.
Internet security experts are gathering at a secretive conference later this week to strategise in their fight against cybercriminals.
Police in London, acting in conjunction with Finnish law enforcement authorities, arrested three suspected virus writers on Tuesday.
Authorities are cracking down on phishing and botnets, but the threats are advancing instead of diminishing, two law enforcement officials said.
There's a 50 percent chance your unprotected Windows PC will be compromised within 12 minutes of going online, says security vendor Sophos.
