Caller ID may be lying to you


The Norman Transcript

NORMAN — Have you ever received a phone call from a telemarketer who became rude and abusive when you refused to listen to their sales pitch? Who hasn’t?

Have you ever tried to report them to their superiors by calling the number that appeared on your Caller ID, only to discover that the number was not in service or actually belonged to some old lady in Phoenix? That’s what is happening to folks across the country as more and more unscrupulous characters discover the benefits of Caller ID spoofing.

Caller ID (CID) spoofing, in its simplest form, allows you (the spoofer) to cause a fake phone number to be displayed by the CID service of whomever you are trying to trick (the spoofee). Instead of your real phone number being revealed to the call recipient, or no number at all, as is the case with *67 CID blocking, CID spoofing allows you to display any number that you like, such as that of the White House or the local pizza parlor.

CID spoofing has been possible since the invention of Caller ID and has been used for many years by law enforcement agencies, private investigators and collection agencies. These groups discovered early on that many people were reluctant to answer the phone if they knew that a police department or collection agency was on the other end. Using expensive equipment, combined with high-priced Primary Rate Interface lines provided by the local telephone companies, they learned that they were often able to trick their targets into answering their calls.

As telephone technology evolved and Internet usage became more pervasive, CID spoofing became a much less expensive proposition.

In 2004, companies such as CovertCall and Camophone began making spoofing services easily available to the general public, enabling anyone with a pocket full of change to engage in the perfectly legal activity of concealing their telephone identity.

A Web search for “caller ID spoofing” shows scores of companies offering CID spoofing, with SpoofCard being the clear front-runner. Many services also offer the ability to record your calls and disguise your voice. You’ve heard voice-altering effects like these in movies; now, for $10 or less, they can be yours. Whether you use these abilities for good or bad is your decision.

Some good causes for which CID spoofing can be used include checking up on anyone that might be trying to avoid the intrusion of your calls, such as your children or even a wayward spouse.

I recently read an amusing interview with a fellow who used CID spoofing to collect thousands of dollars owed him by a previous employer. The company wouldn’t answer the phone when they saw his number being displayed but would answer every time when he spoofed himself as being the human resources director or company president. He collected his money.

Like all technologies, the bad guys also have discovered CID spoofing. They’ve found that people are more likely to reveal private information when they think that their bank or credit card company, or the Social Security Administration, is calling them.

Some credit card companies, along with Western Union, have been stung by CID spoofing scams and tricked into issuing credit cards or wiring money to crooks. Other scams include hacking into cell phone voicemail boxes, as many are set to play back messages when they receive a call from the owner’s phone number. Another scam is called “swatting.” “Swatters” use CID spoofing to call in fake kidnappings and hostage crises to 911.

The Truth in Caller ID Act of 2009, which was signed into law Dec. 22, 2010, prohibits caller ID spoofing for the purposes of defrauding or otherwise causing harm. Personally, I like the idea of being able to conceal my identity any time that I please. You may, too, but keep in mind that it is illegal to do so “with the intent to defraud, cause harm or wrongfully obtain anything of value” (from the FCC website).

Check out the amusing Spoofem.com commercial on Youtube and imagine the possibilities. Afterward, you may not want to trust CID information any more than you’d trust the return address on a piece of mail.
