Online Credit Card Skimming on a Continual Rise – Here's How to Prevent it


Credit card skimming has already been on a rise prior to the pandemic and the trend is most likely to develop in the near future as online shopping has seen a dramatic jump due to the confinement measures imposed in various nations – giving cybercriminals more opportunities to bank upon than ever.

Popularly known as, 'Magecart' moniker, web skimming is the practice of compromising online stores and stealing payment card data in the process. In March, web skimming soared by 26%, as per the data by MalwarebytesLABS.

Credit card skimming is a form of credit card theft where crooks steal victims' credit card credentials and other sensitive information through a skimmer which is a small device constructed to steal information stored on credit cards when victims carry out transactions at ATMs. Lately, the terminology has been expanded to include malicious code that targets payment card data filled on e-commerce websites while making purchases. By either means–hardware or software, skimming attempts to achieve the same goal of performing fraudulent transactions by using the stolen data.

As various nations upgraded their cybersecurity by moving to chip-enabled cards, crooks have also continually adopted new and sophisticated methods to avoid detection. Certain skimming devices are designed to fit into the card reading slot – known as "deep-insert." They are intended to read data from the chips on chip-enabled cards.

Consumers are advised to stay extra cautious as there is not just a single way to fall in the trap of skimming, security experts recommend looking for signs of tampering like chunks of metal or plastic that seem off in dispositions, strange holes, or constituents, not in alignment with the rest of the ATM.

To prevent online skimming, there is not much one can do directly as they can't control the affected software. However, consumers can constantly monitor their card statements to look out for unauthorized transactions. They can use virtual card numbers to make online purchases if the bank offers of can also pay with smartphones; services such as Google Pay and Apple Pay that uses tokenization, replacing the real number with a virtual one, assures a great deal of security for real number by not exposing it. Another way to ensure safety is by making use of an alternative e-wallet service like PayPal.

Recent skimming attacks include a data breach disclosed by Warner Music Group, The American Payroll association's report wherein cybercriminals installed skimming malware on the login page of their website as well as the checkout section by exploiting a vulnerability in the company's CMS. Magecart skimmers also employ Telegram as a means for sending stolen credentials back to its C2 servers.

More than 17,000 Domains Affected with Code which Steals Card Data



Cybercriminals running Magecart operations have added payment card skimming code to more than 17,000 domains with JavaScript files in misconfigured Amazon S3 buckets.

Cybercriminals exploited the lack of access control in Amazon's cloud storage services and affected over 17,000 domains via automated attacks which reconstructed JavaScript code randomly, without monitoring if the code could load a payment page.

The exploit came as a part of Megacart operations, originated in the month of April; attackers injected payment card skimming code to a high number of domains with JavaScript files in poorly configured Amazon S3 buckets which granted writing permissions to the person finding them.

According to the security researchers at RiskIQ, the discovery of these S3 buckets had been automated by the authors of the campaign.

Referencing from the findings made by Yonathan Klijnsma, RiskIQ's head of threat research, "Once the attackers find a misconfigured bucket, they scan it for any JavaScript file (ending in .js). They then download these JavaScript files, append their skimming code to the bottom, and overwrite the script on the bucket."

"Even if your bucket has information that anyone can access, it does not mean everyone should be able to modify the content," he added.

The fact that a large number of websites employing Amazon's cloud storage services fell short in fortifying access to the corresponding assets played a major role for Magecart campaign in realizing its malicious objectives.

Infowars Hit With Card Skimming Malware




As indicated by ZDNet and Dutch security researcher, Willem de Groot, the malware capable of furtively recording payment card details was removed on the 14th of November from the Infowars online store after ZDNet contacted the company's staff.

The site was a recent victim of an especially awful Magecart infection, which hoovered up the details of around 1,600 clients.

Magecart is a strain of malware that objectives online retail stages. Working by quietly recording the payment card details put together by the clients, and after that sending them to a remote server, where they can be utilized for Visa misrepresentation (credit card fraud) , or sold on to various other offenders on the black market.

The malware was covered inside a block of Google Analytics code, and was live for only 24 hours before it was removed says de Groot.

The malware, present on each Infowars store page, just activated itself on the site's checkout pages. As indicated by ZDNet, the code scratched all substance found inside the checkout forms each 1.5 seconds, not before transmitting it to a remote server situated in Lithuania.

As per Jones, Infowars is cautioning clients to be watchful about unapproved installments on their cards. The company additionally trusts that the genuine number of influenced clients might be lower than 1,600, because of a few people re-requesting things amid a similar time period.

An announcement given to ZDNet by Alex Jones considered the hack a " act of industrial and political sabotage," and said that it was "probably carried out by leftist stay behind networks (sic) hiding inside US intelligence agencies.”
The full Alex Jones statement is available below:

This criminal hack is an act of industrial and political sabotage. The corporate press is claiming that a Magento plugin to the shopping cart was the point of entry, but that is not true. Infowarsstore.com has never installed that plugin. We use some of the top internet security companies in the nation and they have reported to us that this is a zero-day hack probably carried out by leftist stay behind networks hiding inside US intelligence agencies.

Magento's top security people have done a site-wide scan and found no security vulnerabilities. And we believe security features we will not mention, appear to have blocked them from getting anyone's credit card numbers.

The hack took place less than 24 hours ago; it is undoubtedly the hacker or hacker group that then reported this to the establishment corporate press in an attempt to scare business away from Infowarstore.com.

Only 1600 customers may have been affected. Most of those were re-orders so their information would not be accessible. Nevertheless, our customer-supporter base is being contacted so they can watch for any unusual charges to their account and rectify them.
