*My Vanilla Card Scam
Gift cards have caused quite a headache for retailers in the last month, exposing another way that fraudulent activity can eat into razor-thin profit margins. Gift card fraud can range from physical theft to cloning to exploiting programming errors on the merchant side.
Some people have been having problems using Vanilla Visa with Private Internet Access (our top recommended VPN provider). Hopefully the company will sort out this problem soon. There is a short-term solution: You can create a Amazon account (using fake personal info) and link it to the Vanilla Visa. Don’t buy gift cards from online auction sites, buy gift cards directly from the store issuing the gift card or from a secure retailer’s website. Don’t buy gift cards off of publicly displayed racks in retail stores. Ask the store cashier to scan the gift card in front of you, in this way you can buy only valid card.
The methods of attack are very similar to what is seen with credit card fraud, but gift card fraud is less widely reported in the news. The reason is that, unlike data breaches that involve credit cards, personally identifiable information (PII) is rarely disclosed. Regardless, it is important for both merchants and customers to know how gift card fraud occurs, so they can recognize the behavior and protect themselves.
On June 1st, Australian retailer Woolworth’s experienced a data breach that led to AUS $1.3 million worth of gift card numbers being leaked online. Several weeks prior, Starbucks had two high-profile gift card incidents – one involved a security researcher that discovered a race condition that allowed him to transfer card balances between cards without deducting any value, and the other involved the auto-load feature on cards that allowed fraudsters to quickly drain attached bank accounts. According to reporting by Brian Krebs, Starbucks itself was not hacked – the customers were.
The article goes on to explain that customers often use the same username/password combination across multiple sites and when a website is hacked, cyber criminals will often take the password dumps and try them on multiple sites. This is what most likely happened to the Starbucks customers; it’s very inconvenient and costly to the victim but avoidable, if good password habits are used.
There are many ways to commit fraud using gift cards and they are very alluring, for many reasons. First, and foremost, there’s a low chance of being prosecuted. The dollar amounts on each individual transaction are relatively small and not enough to garner the attention of large law enforcement agencies that have the ability to catch the perpetrators. Second, it’s very easy to commit fraud. Lastly, it’s easy to convert gift card value into money or merchandise.Vanilla Visa Gift Card Scam
How is gift card fraud commonly committed? There are three primary categories of fraud:Hacking accounts
As described earlier with the Starbucks story, thieves can hack into gift card accounts and quickly drain them of money. If the auto-load feature is turned on, within seconds, a cybercriminal can quickly rack up charges and start the process of moving money off the compromised gift card account.
Another common route is using gift cards to quickly monetize the value in other hacked accounts, such as credit card rewards programs or hotel points.
This is how it works:
*A cybercriminal will obtain the username and password to a person’s credit card rewards program, usually through reused credentials or malware.
*They will log in and check the value of the account. For example, let’s say it’s $5,000.
*Credit card redemption programs offer many different items they can redeem in exchange for points. Several problems exist for the fraudster. They can’t exactly redeem for golf clubs – where would they ship them? Cash back is either redeemed as statement credit or sent as a check to the cardholder – also no good. Gift cards, however, are a perfect way to quickly monetize the hack.
*The redeemer instantly gets an e-gift card number that can be spent immediately, meaning the fraudster can exchange $5,000 worth of points for $5,000 worth of value on an e-gift card. The site will give the fraudster a gift card number on the spot, which can be printed out and used in-store or online.
*The fraudster will then use a service that converts gift cards into cash, such as cardcash.com or cardhub.com. One can usually get 60% of the face value of typical gift cards on sites like this. There are also physical kiosks in malls that offer the same service.
*The fraudster can now effectively convert a point or rewards on a hacked account into real cash.Stealing numbers and cloning cards
Another very common method of gift card fraud is committed is through stealing numbers off physical gift cards. Gift cards work essentially the same as credit cards with a mag stripe—the gift card number is printed on the card for manual key entry and is also encoded on a mag stripe on the back of the card.
The mag stripe number is plain text and can be read with a mag stripe reader purchased for $15 from eBay or an electronics store. Gift cards may or may not have an additional level of security, a PIN number covered with a coating, similar to a lottery ticket, that needs to be scratched off.
Some merchants, such as Starbucks, do not require the customer to enter in a PIN number when using the card. The customer simply swipes the card and they’re good to go. Other merchants do use PIN numbers, which offers an additional layer of protection – the redeemer needs to have the physical card in possession in order to use it.
Gift cards are not usable until they are activated at the cash register. In many stores, gift cards are sitting out in an accessible place. People have been known to steal a stack of cards, bring them home, write down the numbers (or script it out using a mag stripe reader) and then sneak them back into the store and place them on the shelf.
Brazen criminals can write down or take pictures of the numbers down right in the store. From there, it’s a waiting game. Most merchants offer a way to check gift card balances online – the fraudsters will repeatedly check balances on the merchant’s website and wait until they are activated by a legitimate purchase. When they are, transferring balances to another card or converting into cash by using a third-party redeemer drains the balances out.
There are no reported incidents of POS skimmers used to grab gift card numbers, but this attack would work as well.
The addition of a PIN number can delay a fraudster, but not deter them entirely. They can scratch off the coating, revealing the PIN and replace it with a new sticker easily purchased from eBay.
This type of fraud is fairly low-level and does not result in a huge loss to the merchant, but is quite a shock to the customer when the recipient of a gift card tries to redeem it and finds that the balance is zero. Some retailers will reimburse the customer with the face value of the gift card, but this ends up being a reputational hit for the retailer, as well as a headache for the consumer.Vanilla Visa Gift Card Hacked AccountAcquiring numbers in bulk
Slightly more difficult, but much more rewarding, is to acquire gift card numbers in bulk from the issuers, merchant, reward redemption program, etc. This can be done through a multitude of methods, including phishing, SQL injection, social engineering and accidental disclosure.
Accidental disclosure is exactly what happened at Woolworth’s, where an employee at the company had a spreadsheet with 8,000 gift card numbers, totaling AUS $1.3 million. The employee accidentally sent the email to more than 1,000 people. Anyone who received the email could immediately go shopping or start to convert the gift card numbers into cash.Advice for retailers
In-store security is important. Store gift cards behind the counter or locked in a cabinet. It’s not advisable to leave them out in an area that is publicly accessible because of the high probability someone will perpetrate one of the scams described above.
It’s even more important to have good policies and procedures in place for the central handling of gift cards numbers. First, require a PIN for the use of a gift card. Next, on a corporate policy level, never store the gift card PINs with the gift card numbers – keep the two separate. Last, limit online balance look-ups to several per hour, maximum.Advice for customers
The best advice for customers buying gift cards is to only buy gift cards from reputable merchants. Always look at the physical card and look for signs of tampering, such as a scratched off and/or replaced PIN number. Most importantly – keep your receipt. If you get the card home and find it drained of funds, you may be able to recoup your losses by going to the merchant that sold the card or the store where the gift card is redeemable.
Gift card fraud is pretty unsexy when compared with the latest nation-state threat actors exploiting multiple 0-day vulnerabilities, but it is a significant problem that drains money from retailers and consumers alike. By being aware of how this fraud is committed, we can spot the scams and protect ourselves.See how solutions like Tripwire equipped the Walgreens-Boots Alliance to continuously monitor and protect the business, while ensuring systems are reliable and secure.

To most people, un-activated gift cards hanging on a rack in a store are worthless. But to hackers, those cards are just cash waiting to be stolen.
Gift cards have weaker security measures than debt or credit cards, cyber researcher William Caput, tells Wired. The weak security features create a vulnerability, which makes the gift cards valuable to someone who knows how to exploit the security hole. With a little bit of hacking and craftsmanship, a fraudster can spend the money on someone’s card before they do.
Caput tells Wired, in an article about his research, that gift cards are mass-produced with sets of card numbers that follow a simple pattern-- the first set of 10 numbers are identical, the eleventh and twelfth numbers count up from 01 to 99, and the last four digits are random. Caput first discovered this vulnerability--an easy-to-follow pattern--two years ago when he was hired as a white hat hacker to penetration test a large restaurant chain.
With the numerical pattern, Caput says a hacker can check how much money is on specific cards by visiting the restaurant’s or store’s website. Caput says a hacker will need to use software that will enter each sequential combination to enter all 10,000 possibilities for the last four card numbers, but the hacker can cycle through card numbers and see how much money is on those cards that are activated.
Hackers can use the gift cards online or print fraudulent gift cards themselves by taking blank plastic cards and writing magnetized strips onto them with a machine that sells on Amazon.com, Caput says.
’You’re basically stealing other people’s cash through these cards,’ Caput tells Wired. ’You take a small sample of gift cards from restaurants, department stores, movie theaters, even airlines, look at the pattern, determine the other cards that have been sold to customers and steal the value on them.’
Caput warned retailers about the security vulnerabilities. Many companies heeded his advice and added security features to their sites to prevent hackers from testing thousands of card numbers. But he says these changes still don’t prevent someone from taking photos of un-activated card numbers at the store and waiting until someone activates them so they can steal the money.
According to a report released this year by security firm Flashpoint, the number of criminals targeting gift cards has been trending up for the last two years. A vendor selling stolen gift cards on dark web marketplace AlphaBay made over $400,000 in sales in eight months, Flashpoint analyst Liv Rowley tells Wired. The vendor was selling cards from stores like Whole Foods and OfficeMax.
Although many retailers already fixed the vulnerabilities,Caput told Wired that a ’disturbing fraction’ of retailers are still open to hacking. The fix, fortunately, is easy. Caput says retailers shouldn’t leave un-activated cards out in the aisles and they should add tests to their e-commerce sites to prevent hacking software from checking thousands of card numbers for value. Caput also says retailers could add scratch-away covers to cards and require a PIN number to use the card.
