New Botnet Threatens Mac Computers

New Botnet Targets Mac ComputersFor years now, Mac users have flaunted their seeming immunity to computer viruses, malware, and other noxious applications that plague the hearts, minds, and hard drives of PC users. However, there have been exceptions to the Mac's invincible reputation, like the one app from last summer that stole photos and all sorts of other information. According to security software firm Symantec, there's another one on the loose, turning Apple computers into zombies.

The app is (somewhat humorously) called iBotnet, and it runs quietly in the background after its taken control of your Mac computer. It then allows the crooks who distributed the software to use the infected machines for their nefarious means, doing whatever they like. That's the essence of the botnet. Only a few thousand Macs are infected, but, given the general lack of virus protection on most Apple computers, that's a number that could quickly balloon.

What can you do? Well, if you're on a Mac, it's time to start watching what you click and download, just as your PC brethren have been doing for years. And perhaps it's time to be a little less self-sure, too. [From: CNN]

Malicious Infection Turns Your Computer Into a Spam-Sending 'Bot

The newest trend in Internet infection is growing at an alarming rate, according to Breach Security Lab's recently released Web Hacking Incidents Database (WHID) 2008 Annual Report. The attack is called an SQL injection and it works by corrupting the database layer of a Web site. This type of attack, once thought nearly obsolete due to the legwork required of the hacker, was resurrected when the hacking community began automating the process last June, allowing for a 300-percent increase in SQL injections in 2008.

The exploit essentially opens the infected site up to the hacker's whims. Once they gain control, they can install malware ranging from data stealers to viral spam. If you click on an exploited link and become infected, your secure information is compromised and your PC becomes susceptible to control by the infection, acting as a bot to help spread spam and deliver more infections to other computers. This means that infections can have near exponential growth; alarming, since some 500,000 sites have been infected, including government Web sites like the U.S. Department of Homeland Security's.

Major Spam Hub Shut Down



A California Web hosting company that was a major source of spam (as well as a host of child porn, and seller of counterfeit pharmaceuticals and designer goods) has been effectively shut down -- but only after numerous security firms and the Washington Post reported on its activities. The slow process has some Internet security folks claiming that U.S. Internet security laws and law-enforcement agencies are either moving too slow or basically toothless.

The majority of the world's spam, as junk email is known, originated or was controlled by servers at Web hosting firm McColo Corp., based in a sleek, modern 30-story office tower in San Jose. After the two companies that provided McColo with its Internet capacity were shown just how much criminal activity was pumping through the servers, the companies took quick action to shut down McColo's operation.

One of McColo's activities was controlling botnets, essentially computer programs that illegally use remote computers like yours, ours, and everyone else's to send out spam. One of the botnets controlled by McColo sent out up to half a billion spam messages a day with the common messages for penis enlargement pills or other designer drugs. According to Marshal, a security company in the United Kingdom, the botnet activity was responsible for almost 75-percent of the world's junk mail.

FBI Sees Drastic Rise in Computer Crime

FBI Sees Drastic Rise in Computer Crime
The FBI is reporting that computer crime rose dramatically this year and is costing the U.S. tens of millions of dollars.

In particular, two types of attacks have seen an increase in popularity. Botnets spread malicious software via a virus. These Botnets turn infected PCs into unwilling participants in a network of PCs that "recruit" other computers and harvest data. The other type of attacks that have increased in prevalence are so-called "spearfishing" attacks, in which hackers send out official-looking e-mails to collect personal account data from employees of companies.

A third type of attack that is less widespread, but still seeing an increase in use is the "Pump and Dump" scheme, where attackers break into Wall Street firms and drive up the price of stocks only to dump them from their own accounts.

The FBI set up the Internet Crime Complaint Center (IC3) in 2000 to track such attacks. The IC3 currently receives 18,000-20,000 reports of potential computer crime per month, which works out to around 650 attacks per-day. Even the most dangerous neighborhood in the world seems tame by comparison. [From: Reuters]
