Cyber criminals are taking advantage of our increasing reliance on computers and the Internet, CNN reports on June 22. Panda Security, a Spain-based antivirus maker, has been monitoring an onslaught of links with malicious software, or “malware,” on Twitter that tag hot topics such as the Air France crash, the NBA finals and the new iPhone.

“Cyber criminals are creating thousands of messages on Twitter embedded with words involving trending topics and malicious URLs,” states Sean-Paul Correll, a threat researcher for Panda Labs.

The growing sophistication of malware attacks mirrors the growing threat — and cash — generated by online crime. Already, cyber crime is estimated to cost companies and consumers more than $100 billion worldwide. Some officials claim it has now eclipsed illegal drugs as a criminal moneymaker.

Cyber crime is one of the few industries benefiting from the financial crisis. Last year, antivirus maker McAfee saw a 500 percent increase in malware types — more than the company had seen in the previous five years combined. In the United States, the FBI reported a 33 percent increase in Internet crime last year.

Companies lost an average of $4.6 million in intellectual property last year, according to a survey of 1000 firms worldwide by Purdue University and McAfee.
