Phishing continues to become more sophisticated, more effective, and more prevalent. According to Symantec, a 52% increase in phishing scams occurred in July alone. Computerworld reports that basic phishing emails successfully led to corporate bank accounts being completely drained. Criminal hackers waited until Pennsylvania schools administrators were on vacation, then used simple  money transfers to liquidate over $440,000 between December 29 and January 2.

Much of the phishing that occurs today is "spear phishing," in which the spammers concentrate on a localized target, generally an individual with control over a company's checkbook. This insidious type of phishing occurs when a recipient clicks a link, either in the body of an email or on the spoofed website linked in the email, and a download begins. That download is almost always a virus with a remote control component , which gives the phisher full access to the user's data, including user names and passwords, credit card and bank account details, and Social Security numbers. The malicious software can attach itself to the victim's web browser, where it waits for the victim to log into a bank site before launching. When the victim does log into his or her bank account, the software sets up new payees and transfers money to the criminal hacker.

In the school hack, the software added 42 people to its payroll during Christmas break and quickly began paying them. The issuing bank received 74 transfer requests during the four day period.

When consumers' bank accounts are emptied, federal regulations limit their liability to $50, as long as the victim reports the theft within a set time frame. But things are a lot more complicated for corporations and other entities. Whether or not the victim is responsible for the missing cash varies from bank to bank.

Protect your yourself. First of all, don't click on any links in an email unless you are 100% sure of its legitimacy. Whenever I receive an electronic statement from a bank or credit card company, I go to my favorites menu or type in the address manually, rather than clicking the link within the email. I take this extra step because I'm only 99.9% sure that the email is legitimate. You should also consider getting a credit freeze. Go to ConsumersUnion.org and follow the steps for your particular state. This is an absolutely necessary tool to secure your credit. In most cases, it prevents new accounts from being opened in your name. This makes your Social Security number useless to a potential identity thief. And invest in identity theft protection. Not all forms of identity theft protection can be prevented, but identity theft protection services can dramatically reduce your risk. Make sure that your web browser is updated to the latest version, since an outdated web browser is often riddled with holes that worms can crawl through. Make sure that your Internet security software is updated and set to run automatically. And check your bank statements online frequently.
