Computer Hijackings Increase by 50% in 2008

Computer Hijackings Increase by 50 Percent in 2008

There are plenty of malicious programs that can do plenty of nasty things to plenty of computers, but, far and away, the most common type of attack results in what is known as a zombie. A zombie is a hijacked computer that can be remote-controlled by the attacker and made to do his or her bidding. According to a recent study by security firm McAffee, there were 50-percent more zombie computers on the Internet in 2008 than there were the year previous.

The report goes on to state that a frightening 18-percent of all computers in the U.S. are infected, meaning that, almost certainly, one of the computers you use (or one of the computers your friends use) is infected. Largely responsible are malicious programs like Conficker that trick users into installing or running them and then run in the background, responding to signals sent out by zombie ringleaders. Some can exploit flaws in an application's security, injecting themselves into your computer without your ever having prompted them.

To avoid being a sad statistic, always keep your computer up to date, and always, always, run a virus scanner. [From: BBC News]

Spam Levels Still Low After November Shut-Down

Spam Levels Still Low After November Shut-Down

A few months ago, the Federal Trade Commission worked to shut down the spammy behavior of one California-based ISP called McColo. The company was found to be hosting a number of so-called botnets (groups of computers that send e-mails and spread malicious software) that were responsible for a huge portion of the world's spam. When McColo was shut down, inboxes around the world breathed a sigh of relief. Now, two months later, spam levels have still not recovered.

According to virus-protection company McAfee, spam levels are still at only 60-percent what they were before the take-down in November. Meanwhile, Symantec is a bit more pessimistic, saying we're at 80-percent. Neither, however, is optimistic enough to say that spam levels will stay this low, with estimates indicating that by June or July we'll have just as much spam as before -- and likely more.

So, enjoy these halcyon days while you can, as they won't last for long. [From: ars technica]
