Spammers use your cat's name to sell you Viagra
Spammers have started using spyware to steal personal information so they can customise the subject lines of unsolicited emails to increase their chances of being read.
Research by email security firm MessageLabs has revealed that spammers are targeting companies and individuals with unsolicited messages that have subject lines containing names, familiar words or phrases that have been stolen from the victim's computer.
This is possible once a computer has been compromised with a piece of spyware that can track keystrokes or scan documents and send the information back to the spammer.
MessageLabs' senior anti-spam technologist Matt Sergeant said the spam target is more likely to open an email if the subject line contains information that is directly relevant to them or their job.
"The idea is that by using familiar words and phrases, such as passwords, a pet's name or a company name, users will be more likely to open the email," Sergeant said.
The volume of spam has increased dramatically over the past two years, so much so that some security companies say the majority of email traffic is now spam. The problem intensified with the emergence of viruses and Trojans that were designed to infect unprotected computers and turn them into spam-sending zombies.
As the spam problem grows, so does the anti-spam industry; as a result, the spammers have started colluding with malware writers to try and increase their hit rates, according to MessageLabs.
