Hiding in Plain Sight
Over the holidays when our family is all together, we always try to watch A Christmas Story. There are so many memorable moments in the movie, from the triple-dog-dare-you, tongue-frozen-to-the-flagpole scene to the leg lamp breakage. When the story revolves around Ralphie and the Little Orphan Annie secret decoder ring, it triggers my childhood memories of having a similar decoder ring that came with a pair of P.F. Flyers sneakers (think pre-Nike and Adidas). This year, our movie-watching led to a storytelling session of techniques worthy of any spy movie for passing secret notes. Many of the examples were like the decoder ring—they used some sort of secret alphanumeric table as a key to solve the cryptic message. In other words, we were talking about a rudimentary form of encryption, which, in today's technology, renders data useless to those without a key, whether they're bad guys or good guys.
But our conversation didn't stop there. I told a childhood story of dipping a toothpick in lemon juice and writing a message on paper. After the juice dried, the message became invisible, and I would then write an innocuous—and visible—message on the paper with pen or pencil. The recipient would carefully hold the paper over a flame to slowly reveal the hidden message. (Kids, try this only under adult supervision!) Little did I know I was using a technique called steganography—hiding a message within another message—that people also use today to protect information online.
Various forms of the technique date back to Greek civilization when untrusted messengers had to convey sensitive or classified information, or a message was at risk of being intercepted. (There is an entertaining and educational video on steganography by Richard Buckland, a professor at the University of New South Wales in Australia.) Today, technology has created a new technique in the form of digital steganography, which is the practice of hiding an image, audio, or data file within another image, audio, or data file.
A recent article in infoRisk Today highlighted the darker side of steganography, with its use by the criminal element. That article prompted me to conduct more research on the technique as a payments risk. From a cybersecurity standpoint, the greatest risk to consumers appears to be when the criminal hides a malware file within an image, audio, or other data file that, when opened, will load malware onto the device for future eavesdropping or control. Such an event could lead to the compromise of PII (or personally identifiable information), online credentials, or other sensitive information on the device without the owner's knowledge. In an August 2017 release, Kaspersky Lab warned about the difficulty for existing data protection processes to detect embedded malicious code.
Account takeover fraud is a major criminal activity that generally begins with the compromise of an individual's legitimate banking log-in credentials. A criminal who obtains this information can execute payment transaction fraud and, ultimately, synthetic identity fraud (see last week's post). While there are valid uses for steganography as an alternative to encryption, the criminal element will continue to develop uses of digital steganography to further their criminal operations and, as the infoRisk article notes, this usage is becoming more sophisticated and harder to detect.

A New You: Synthetic Identity Fraud
With the start of the new year, you may have resolved to make a change in your life. Maybe you've even gone so far as to pledge to become a "new you." But someone may have already claimed that "new you," stealing your credentials and using them to create a new identity. Identity theft is a growing problem, resulting in millions of dollars in damage around the world. And now there is a modern twist to this old and costly problem: synthetic identity fraud. Panelists at a forum convened by the Government Accountability Office (GAO) define this problem as a "crime in which perpetrators combine real and/or fictitious information, such as Social Security numbers and names, to create identities with which they may defraud financial institutions, government agencies, or individuals." (Read forum highlights on the GAO website.) According to the U.S. Federal Trade Commission, synthetic identity fraud is the "fastest growing and hardest to detect" form of identity theft.
This graphic from the GAO illustrates how this type of identity fraud differs from what we have traditionally defined as identity theft.
As this image shows, in traditional identity fraud, the criminal pretends to be another (real) person and uses his or her accounts. In synthetic identity fraud, the criminal establishes a new identity using a person's real details (such as social security number), combining this information with fictitious information to create a new credit record.
The challenge for the payments industry is determining whether an identity is planted or legitimate. For example, parents with excellent credit histories sometimes add their children to their existing credit accounts to give their children the benefit of their positive financial behavior. This action allows the children to kick-start their own credit records. Similarly, a criminal could plant a synthetic identity in an existing credit account and from there build a credit history for this identity. (In many cases, the criminal works for years on building a strong credit history for that false identity before "cashing out" and inflicting financial damages on a large scale.)
So what can consumers do to protect themselves? Here are some simple ways to make it harder for a thief to steal your personal information:
- Shred documents containing personal information.
- Do not provide your social security number to businesses unless you absolutely have to.
- Use tools that monitor credit and identity usage.
- Freeze your credit account as well as that of any of your minor children.
- Check your accounts regularly to ensure that all transactions are legitimate and report any suspicious activity immediately.
Staying informed about synthetic identity fraud tactics and taking these steps to protect yourself can help you get one step closer to (preventing) "a new you."
