Magecart Hackers Hide Stolen Credit Card Data Into Images for Evasive Exfiltration

Magecart Hackers Hide Stolen Credit Card Data Into Images for Evasive Exfiltration
July 09, 2021Ravie Lakshmanan
Cybercrime actors part of the Magecart group have latched on to a new technique of obfuscating the malware code within  comment blocks  and encoding stolen credit card data into images and other files hosted on the server, once again demonstrating how the attackers are  continuously improving  their infection chains to escape detection. "One tactic that some Magecart actors employ is the dumping of swiped credit card details into image files on the server [to] avoid raising suspicion," Sucuri Security Analyst, Ben Martin,  said  in a write-up. "These can later be downloaded using a simple  GET request  at a later date." Magecart is the umbrella term given to multiple groups of cybercriminals targeting e-commerce websites with the goal of plundering credit card numbers by injecting malicious JavaScript skimmers and selling them on the black market. Sucuri attributed the attack to  Magecart Group 7  based on overlaps in the tactics, techniques, and procedures (TT

New Hack Lets Attackers Bypass MasterCard PIN by Using Them As Visa Card

New Hack Lets Attackers Bypass MasterCard PIN by Using Them As Visa Card
February 19, 2021Ravie Lakshmanan
Cybersecurity researchers have disclosed a novel attack that could allow criminals to trick a point of sale terminal into transacting with a victim's Mastercard contactless card while believing it to be a Visa card. The research, published by a group of academics from ETH Zurich, builds on a study  detailed last September  that delved into a PIN bypass attack, permitting bad actors to leverage a victim's stolen or lost Visa EMV-enabled credit card for making high-value purchases without knowledge of the card's PIN, and even fool the terminal into accepting unauthentic offline card transactions. "This is not just a mere card brand mixup but it has critical consequences," researchers David Basin, Ralf Sasse, and Jorge Toro said. "For example, criminals can use it in combination with the previous attack on Visa to also bypass the PIN for Mastercard cards. The cards of this brand were previously presumed protected by PIN." Following responsible disclosu

New PIN Verification Bypass Flaw Affects Visa Contactless Payments

New PIN Verification Bypass Flaw Affects Visa Contactless Payments
September 07, 2020Ravie Lakshmanan
Even as Visa issued a warning about a new JavaScript web skimmer known as Baka , cybersecurity researchers have uncovered an authentication flaw in the company's EMV enabled payment cards that permits cybercriminals to obtain funds and defraud cardholders as well as merchants illicitly. The research , published by a group of academics from the ETH Zurich, is a PIN bypass attack that allows the adversaries to leverage a victim's stolen or lost credit card for making high-value purchases without knowledge of the card's PIN, and even trick a point of sale (PoS) terminal into accepting an unauthentic offline card transaction. All modern contactless cards that make use of the Visa protocol, including Visa Credit, Visa Debit, Visa Electron, and V Pay cards, are affected by the security flaw, but the researchers posited it could apply to EMV protocols implemented by Discover and UnionPay as well. The loophole, however, doesn't impact Mastercard, American Express, and JC

January 30, 2020Wang Wei
Remember the recent payment card breach at Wawa convenience stores ? If you're among those millions of customers who shopped at any of 850 Wawa stores last year but haven't yet hotlisted your cards, it's high time to take immediate action. That's because hackers have finally put up payment card details of more than 30 million Wawa breach victims on sale at Joker's Stash, one of the largest dark web marketplaces where cybercriminals buy and sell stolen payment card data. As The Hacker News reported last month, on 10th December Wawa learned that its point-of-sale servers had malware installed since March 2019, which stole payment details of its customers from potentially all Wawa locations. At that time, the company said it's not aware of how many customers may have been affected in the nine-month-long breach or of any unauthorized use of payment card information as a result of the incident. Now it turns out that the Wawa breach marked itself in the

The Indonesian National Police in a joint press conference with Interpol and cybersecurity firm Group-IB earlier today announced the arrest of three Magecart-style Indonesian hackers who had compromised hundreds of international e-commerce websites and stolen payment card details of their online shoppers. Dubbed ' Operation Night Fury ,' the investigation was led by Interpol's ASEAN Cyber Capability Desk, a joint initiative by law enforcement agencies of Southeast Asian countries to combat cybercrime. According to the press conference, all three accused (23, 26, and 35 years old) were arrested last year in December from Jakarta and Yogyakarta and charged with criminal laws related to the data theft, fraud, and unauthorized access. "The operation is still ongoing in the other five ASEAN countries with which the intelligence was also shared. This case marks the first successful multi-jurisdictional operation against the operators of JavaScript-sniffers in the re

January 16, 2019Mohit Kumar
Magecart strikes again, one of the most notorious hacking groups specializes in stealing credit card details from poorly-secured e-commerce websites. According to security researchers from RiskIQ and Trend Micro, cybercriminals of a new subgroup of Magecart, labeled as "Magecart Group 12," recently successfully compromised nearly 277 e-commerce websites by using supply-chain attacks. Magecart is the same group of digital credit card skimmers which made headlines last year for carrying out attacks against some big businesses including Ticketmaster , British Airways , and Newegg . Typically, the Magecart hackers compromise e-commerce sites and insert malicious JavaScript code into their checkout pages that silently captures payment information of customers making purchasing on the sites and then send it to the attacker's remote server. However, the researchers from the two firms today revealed that instead of directly compromising targeted websites, the Magecart G

The US-CERT has released a joint technical alert from the DHS, the FBI, and Treasury warning about a new ATM scheme being used by the prolific North Korean APT hacking group known as Hidden Cobra . Hidden Cobra, also known as Lazarus Group and Guardians of Peace, is believed to be backed by the North Korean government and has previously launched attacks against a number of media organizations, aerospace, financial and critical infrastructure sectors across the world. The group had also reportedly been associated with the WannaCry ransomware menace that last year shut down hospitals and big businesses worldwide, the SWIFT Banking attack in 2016, as well as the Sony Pictures hack in 2014. Now, the FBI, the Department of Homeland Security (DHS), and the Department of the Treasury have released details about a new cyber attack, dubbed " FASTCash ," that Hidden Cobra has been using since at least 2016 to cash out ATMs by compromising the bank server.

Researcher spots an ATM Skimmer while on vacation in Vienna
June 26, 2016Mohit Kumar
We have heard a lot about ATM skimmers, but it's nearly impossible to spot one. Some skimmers are designed to look exactly like the card slot on the original machine and attached to the front, and others are completely hidden inside the ATM. But, during his vacation in Vienna, Austria, cyber security expert Benjamin Tedesco spotted an ATM skimmer that was totally unrecognizable. Tedesco was hanging out in Vienna and when about to draw some cash from a cash machine outside St. Stephen's Cathedral, he decided to do a quick visual inspection of the ATM machine and surprisingly spotted the dodgy device attached to it. Warning: Beware of Skimming Devices Installed on the ATM Vestibule Doors . That was a credit card skimmer – a perfect replica of the actual card reader that was designed to steal credit card information of users when they swipe their card to take off cash from the ATM. "Being security paranoid, I repeated my typical habit of checking the card read

Security researchers from Newcastle University in the UK have found a way to steal larger amounts of money from people's pockets using just a mobile phone, due to a security glitch Visa's contactless payment cards. Contactless payment cards use a cryptoprocessor and RFID technology to perform secure transactions without a need to insert the card in a reader, even an NFC-equipped mobile device may also be used as a payment card. But there is a specified limits country-wise. Contactless payment cards are meant to have a limit of £20 per purchase in UK, using which shoppers can buy things by simply tapping their card on a scanner, without having to type in a PIN. But exploiting a flaw in its protocol could allow cyber criminals to manipulate the cards to transfer up to $999,999.99 in foreign currency into a scammer's account. Researchers on Wednesday at the 21st ACM Conference on Computer and Communications Security, detailed the attack which rely on a "rogue POS te

January 22, 2014Swati Khandelwal
Cyber Criminals will not let any way out without making Money. Another huge Credit Card theft and this time they targeted Gas Stations. 13 men were suspected and charged for stealing banking information, using Bluetooth enabled Credit Card Skimmers planted on the gas stations throughout the Southern United States. They made more than $2 Million by downloading the ATM information, as well as PIN numbers from the gas pumps and then used the data to draw cash from the ATMs in Manhattan. Manhattan District Attorney Cyrus R. Vance explained the operation that the skimming devices were internally installed so was undetectable to the people who paid at the pumps and the devices were Bluetooth enabled, so it did not need any physical access in order to obtain the stolen personal identifying information. " By using skimming devices planted inside gas station pumps, these defendants are accused of fueling the fastest growing crime in the country. Cybercriminals and ident

Hackers behind TARGET data breach looking for Pro-cracker to decrypt Credit card PINs
January 10, 2014Swati Khandelwal
I think you haven't forgotten the massive data breach occurred at TARGET , the third-largest U.S. Retailer during last Christmas Holidays. People shop during Black Friday sales in which over 40 million Credit & Debit cards were stolen, used to pay for purchases at its 1500 stores nationwide in the U.S. TARGET officially confirmed that the encrypted PINs (personal identification numbers) of payment cards were stolen in the breach, since the stolen pin data were in encrypted form so they were confident that the information was " Safe and Secure ", because PIN cannot be decrypted without the right key. The Breach was caused by a malware attack, that allowed the criminals to manipulate Point of Sale (PoS) systems without raising red flags and the card numbers compromised in the breach are now flooding underground forums for sale. Possibly a group of Eastern European cyber criminals who specializes in attacks on merchants and Point-of-Sale terminals either attached a physical device
