Huddle House reveals malware intrusion in its POS systems
February 4, 2019
https://cyware.com/news/huddle-house-reveals-malware-intrusion-in-its-pos-systems-22a99aed

On Friday, restaurant chain Huddle House disclosed a malware attack which occurred on one of its POS systems. Apparently, perpetrators compromised a third-party POS data system through remote access and deployed malware.
The chain believes payment-related information may be at risk since this attack might have affected other systems at different locations having Huddle House franchises.

In its press release, the restaurant chain mentions that the attack affects transactions made since August 2017. “If you used a payment card at a Huddle House location between August 1, 2017 and present, your payment card information may be at risk.

Users who provided their cards at these POS systems have been advised by Huddle House to review and monitor their payment statements for suspicious activities. In addition, the chain has also informed them to avail free credit monitoring services provided by the company, as required under the law.

Cards Used at 137 Restaurants Exposed by Point-of-Sale Breach
February 19, 2019
https://www.bleepingcomputer.com/ne...-restaurants-exposed-by-point-of-sale-breach/

North Country Business Products point-of-sale and security solutions provider with roughly 6500 customers around the Midwest has disclosed a data breach which led to the exposure of payment information for clients who used their credit and debit cards at 137 restaurants.

According to the company's data breach notification, North Country first observed that suspicious activity was present on some of its clients' networks on January 4 and a joint investigation with a third-party cybersecurity forensic firm established that the cause was malware deployed on its partner restaurants' networks.
As detailed in the notification breach hosted at ncbpdataevent.com

North Country also said that the bad actors who deployed the malware were potentially able to gain access to "the cardholder’s name, credit card number, expiration date, and CVV."

DMSniff Point-of-Sale Malware Silently Attacked SMBs For Years
March 13, 2019
https://www.bleepingcomputer.com/ne...ale-malware-silently-attacked-smbs-for-years/

A Point-of-Sale (POS) malware which uses a domain generation algorithm to create command-and-control domains on the fly was deployed in attacks against small and medium-sized businesses during the last past four years—since at least 2016—according to a team of security researchers from Flashpoint.

The Flashpoint team believes that the malware they dubbed DMSniff "could be gaining an initial foothold on devices either by using brute-force attacks against SSH connections or by scanning for vulnerabilities and exploiting those."
[...] usage of a domain generation algorithm (DGA) to generate command-and-control domains on the spot unquestionably sets it apart from other similar malware.

"This technique is valuable to an attacker because if domains are taken down by law enforcement, technology companies, or hosting providers, the malware can still communicate and receive commands or share stolen data," said the researchers.

During their analysis, the research team "found that this malware was primarily utilized to target small to medium-sized businesses such as restaurants and theaters," as well as other entertainment businesses which use point-of-sale terminals, the second most-targeted network asset behind database servers according to last year’s Verizon Data Breach Investigations Report.

Checkers restaurant chain discloses card breach
POS malware discovered installed at 102 Checkers and Rally's restaurants
May 30, 2019
https://www.zdnet.com/article/checkers-restaurant-chain-discloses-card-breach/

Checkers and Rally's, one of the biggest drive-thru restaurant chains in the US, disclosed a security incident yesterday that impacted over 100 locations.

The malware was designed to collect information from the magnetic stripe of payment cards and was capable of detecting and extracting data such as the cardholder name, payment card number, card verification code, and expiration date.
15% OF CHECKERS' AND RALLY'S RESTAURANTS IMPACTED
Most of the impacted restaurants had POS malware installed on their systems between early 2018 and 2019; however, some restaurants were infected in 2017, and the earliest infection date was in September 2016. Most of the restaurants were cleaned in April 2019, when Checkers appears to have discovered the intrusion.

Only customers who paid for meals and other products using their payment cards during infection periods are impacted.

Two Deer Valley Resort restaurants hit with POS data breach
August 1, 2019
https://www.scmagazine.com/home/retail/two-deer-valley-resort-restaurants-hit-with-pos-data-breach/

The Mariposa and the Royal Street Café in Deer Valley, Colo., are informing customers that their payment card information may have been compromised after an unauthorized party hacked the point-of-sale system of a resort operator that runs both restaurants.

The two Deer Valley Resort restaurants discovered on May 17 that an unauthorized person had gained access to their payment card system from January 10-28. During that period, cardholders’ names, payment card numbers, expiration dates, and internal verification codes were read off their payment cards’ magnetic strips.
Deer Valley Resort said that once the intrusion was detected, the malware was removed, outside cybersecurity and law enforcement were called in to help, and the banks that issue the payment cards involved were informed so that each could initiate heightened monitoring.

The company did not release how many people may have been affected by the breach.

Four U.S. Food Chains Disclose Payment Card Theft via PoS Malware
October 3, 2019
https://www.bleepingcomputer.com/ne...-disclose-payment-card-theft-via-pos-malware/

Hackers caused havoc at four restaurant chains in the U.S. over the summer after compromising their payment systems with malware that stole customers' payment card information.

In the last two days, McAlister's Deli, Moe’s Southwest Grill, Schlotzsky’s, and Hy-Vee disclosed publicly that their networks were infected with point-of-sale malware copying data from cards used in person at certain locations.
3 months of compromise
Yesterday, the three Focus Brands subsidiaries provided details about a payment card security incident affecting corporate and franchised restaurants (1, 2, 3). The intrusion was ended on July 22 for all three chains although it had started at different dates.
At Moe’s and McAlister’s, the attackers scraped the information beginning April 29 while at Schlotzsky’s the operation began earlier, on April 11.

As payment card data passed through a restaurant's server, the PoS malware copied from the card's magnetic stripe the card number, expiration date, and internal verification code; the cardholder's name was also available in some cases.

Catch Restaurants Disclose Credit Card Stealing Malware Incident
November 23, 2019
https://www.bleepingcomputer.com/ne...sclose-credit-card-stealing-malware-incident/

Catch Hospitality Group has disclosed that point-of-sale systems (POS) at NYC hotspots Catch NYC, Catch Rooftop, and Catch Steak were infected with malware that allowed attackers to steal credit card information from customers.

According to Catches 'payment card incident' notice, the POS malware was active at Catch NYC and Catch Rooftop between March 19, 2019 and October 17, 2019. For Catch Steak, which opened for business on September 18th, the malware was active between September 17, 2019 and October 17, 2019.
On infected devices, the malware would attempt to steal track data encoded on the magnetic stripe of credit cards.

Catch explains that not all POS devices were affected and they use two different point-of-sale (POS) devices when customers make payments; one that is brought to your table by waitstaff and stationary ones at the bar and where the waitstaff enter orders. As the portable POS devices utilize point-to-point encryption, payments at the table were not affected.

"[...] The cards involved in this incident are cards used at the bar or in the rare circumstances that a card was swiped at the device where waitstaff enter orders."

Church's Chicken Warns of Possible Data Breach
November 22, 2019
https://www.infosecurity-magazine.com/news/churchs-chicken-warns-of-possible/

An American restaurant chain has warned of a possible data breach after detecting unauthorized activity in a computer system used to process payments.

Church's Chicken launched an investigation after noting the suspicious behavior at the end of October. The company has stated that any previous unauthorized third-party access that may have occurred has been halted.

"Although our investigation is ongoing, what we currently know suggests that payment cards used at certain restaurants in 2019 may have been impacted," said a Church's spokesperson.
Cajun Operating Company, commonly known as Church's Chicken or Church's, operates a string of restaurants in the United States and throughout the world.

A spokesperson wrote: "The Church’s system uses multiple payment processing systems and, as a result, not all Church’s restaurants—and none of our franchised locations—are believed to be impacted by this incident."
A list of 130 restaurants in Alabama, Arkansas, Florida, Georgia, Illinois, Louisiana, Mississippi, Missouri, South Carolina, Tennessee, and Texas that may have been impacted has been published by the company on its website.

Updates will be posted to a specially created page on the company's website www.churchs.com/security as they emerge.
A spokesperson wrote: "Church’s will provide updates once we have completed our investigation and know more about any payment cards that may have been impacted."

Fin7 behind DiBella’s data breach affecting 305,000 cards
November 27, 2019
https://www.scmagazine.com/home/sec...-dibellas-data-breach-affecting-305000-cards/

Fifteen months after DiBella’s Old Fashioned Submarines was notified by the FBI and credit card companies of a data breach the sandwich shop chain has issued a notice informing its customers of the incident.
The company reported its stores in Connecticut, Indiana, Michigan, Ohio, New York and Pennsylvania may have had the information on as many as 305,000 payment cards compromised.

The majority of the locations were victimized between March 22, 2018 and December 28, 2018 with its Cranberry, Penn. store possibly being hit as early as September 2017. The customer data involved included individual names, payment card numbers, expiration dates, and CVV numbers, DiBella’s stated.
DiBella’s has not yet returned an SC Media inquiry into why the company waited until now to disclose the issue.

DiBella Security Notice

According to law enforcement, the sophisticated cybercrime syndicate, FIN7, was behind the attacks and had worked to potentially gain access to payment card data on our store information systems.

Because of the sophistication of FIN7 and the complexity of the attack, our contracted forensics firm was not able to immediately identify the root cause of any compromise for several months until a particular kind of malicious software, or “malware” was discovered on some DiBella’s store systems.
According to the forensics investigation, this malware could have enabled the theft of payment card data from DiBella’s store systems.

Wawa discloses 9-month data breach affecting "potentially all" locations
December 19, 2019
https://www.cbsnews.com/news/wawa-discloses-9-month-data-breach-affecting-potentially-all-locations/

The popular East Coast convenience store chain Wawa announced Thursday that it experienced a malware attack spanning more than nine months earlier this year. Customers' credit and debit card numbers, expiration dates, and cardholder names were potentially exposed in the breach, which impacted "potentially all" of the chain's hundreds of locations.

In a letter to customers, Wawa CEO Chris Gheysens said that the breach is believed to have begun at some locations on March 4, 2019, before spreading to others. "Although the dates may vary and some Wawa locations may not have been affected at all, this malware was present on most store systems by approximately April 22, 2019," Gheysens wrote.
The company's information security team discovered the breach on December 10, and blocked and contained it by December 12, Gheysens said.

"At this time, we believe this malware no longer poses a risk to Wawa customers using payment cards at Wawa," he wrote.

One Day, Three Credit Card Data Breach Notifications
December 22, 2019
https://www.bleepingcomputer.com/news/security/one-day-three-credit-card-data-breach-notifications/

On the same day this week, two restaurants and a convenience store, all with locations across the U.S., disclosed security breach incidents that may have enabled attackers to steal customer payment card data.
Wawa store, food market, coffee shop, gas pump
The most prominent on this shortlist is Wawa convenience store chain, with all its locations potentially impacted starting March 4, 2019. [...]
Islands restaurants
The number of Islands restaurants impacted by the PoS malware incident disclosed on the same day as Wawa is 60. Most of them are in California, other locations being in Arizona, Hawaii, and Nevada.

The PoS malware campaign began on February 13 and kept at it until September 27, compromising locations on various dates. It searched for data on the magnetic stripe that contained the cardholder name, card number, expiration date, and internal verification code.
Islands restaurants' notification states that malware is no longer present on payment card processing devices at its locations.

Champagne French Bakery Cafe
The restaurant announced the data breach on the same day as Wawa but details are different. Following an alert regarding PoS malware, Champagne initiated an investigation with the help of a computer forensics company.
The inspection revealed that PoS malware had been installed starting February 13 at various locations. Starting this date and continuing through September 27, "malware was installed on certain point-of-sale devices in our restaurants that were used for payment card transactions," reads the notification.

Neither Champagne nor Islands provide free identity protection and credit monitoring services but inform their customers once a year they can request a free copy of their credit report.

Wawa facing lawsuits over data breach at all of its stores
December 27, 2019
https://apnews.com/1d4d0d09c00ec8c19f40ce4ee4ae95d5

The Wawa convenience store chain is facing a wave of lawsuits over a data breach that affected its 850 locations along the East Coast.
Wawa Inc. discovered malware on its payment processing servers this month before stopping the breach Dec. 12, the company has said.

The Philadelphia Inquirer reported Friday that at least six lawsuits seeking class-action status have been filed in federal court in Philadelphia.

“The data breach was the inevitable result of Wawa’s inadequate data security measures and cavalier approach to data security,” said one suit, filed by the law firm Chimicles Schwartz Kriner & Donaldson-Smith, of Haverford.
A Wawa spokesman declined to comment on the pending litigation.
The breach affected all stores, which stretch along the East Coast from Pennsylvania to Florida. In-store payments and payments at fuel dispensers were affected, but cash machines were not.

Rutter's store chain discloses security breach involving POS malware
February 14, 2020
https://www.zdnet.com/article/rutters-store-chain-discloses-security-breach-involving-pos-malware/

US store chain Rutter's disclosed a security breach today. The company says hackers gained access to its stores' network system and planted malware that collected payment card details as they were being processed.
Stores in Pennsylvania and West Virginia were impacted, Rutter's said today in a press release and a notice posted on its website.

For most locations, the malware was present between October 1, 2018 through May 29, 2019, however, for some stores, the infection timeline is different. See this page for details about the infection timeline of Rutter's stores.
In most cases, the malware is believed to have collected for the user's name, card number, expiration date, and internal verification code. For users who paid with cards at an EMV-capable POS device, Rutter's said it believes the malware collected only the card number and expiration date.
RUTTER'S LEARNED OF THE BREACH FROM A THIRD-PARTY
Rutter's said it learned about the incident following "a report from a third party." It didn't say when it learned of the malware infection, but that the investigation into the incident concluded a month ago, on January 13, 2020.

Two North American hospitality merchants hacked in May and June
...one company had three different strains of point-of-sale (POS) malware on its network
October 4, 2020
https://www.zdnet.com/article/two-north-american-hospitality-merchants-hacked-in-may-and-june/

In a security alert published on Thursday, US payments processor Visa revealed that two North American hospitality merchants were hacked and had their system infected with point-of-sale (POS) malware earlier this year.

POS malware is designed to infect Windows systems, seek POS applications, and then search and monitor the computer's memory for payment card details that are being processed inside the POS payments apps.

"In May and June 2020, respectively, Visa Payment Fraud Disruption (PFD) analyzed malware samples recovered from the independent compromises of two North American merchants," Visa said.
Click to expand...

JUNE HACK: HACKERS USED THREE DIFFERENT POS MALWARE STRAINS
Of the two incidents, the second one that occurred in June is the most interesting, from an incident response (IR) perspective.
Visa said it found three different strains of POS malware on the victim network — namely RtPOS, MMon (aka Kaptoxa), and PwnPOS.

The reason why the malware gang deployed three malware strains is unknown, but it could be that attackers wanted to make sure they get all the payment data from across different systems.
Click to expand...

MAY HACK: THE ENTRY POINT WAS A PHISHING EMAIL
They were, however, able to determine the entry point in the first hack, which occurred in May.
The POS malware used in this incident was identified as a version of the TinyPOS strain.

"The recent attacks exemplify threat actors' continued interest in targeting merchant POS systems to harvest card present payment account data," Visa said.

ModPipe malware decrypts Oracle point-of-sale database passwords
November 12, 2020
https://www.bleepingcomputer.com/ne...ypts-oracle-point-of-sale-database-passwords/

Security researchers have discovered a new malware geared with modules that target Oracle Micros Hospitality RES 3700 point-of-sale systems, one of the most widely used management software in the hospitality industry.

Named ModPipe, the malware is a modular backdoor that can steal the passwords for the PoS system databases by decrypting them from Windows registry values.
Risky modules unknown
One particularity for ModPipe is its modular architecture that allows extending its features through downloadable components, such as GetMicInfo, used for decrypting database passwords.
Researchers at ESET found some basic ModPipe components at the end of 2019.
Click to expand...

The researchers still don't know how the malware compromises the PoS systems but they figured out its architecture, which includes an initial dropper, a persistent loader, the main module, a networking module, and downloadable components.

Details about the decryption mechanism are not public, suggesting that the threat actor may have reversed engineered the software for Oracle’s MICROS RES 3700 Restaurant POS System to understand how the passwords are encrypted and decrypted.
Alternatively, they could have gotten the info from a 2016 data breach that affected Oracle’s Micros PoS division, or by buying the code on a cybercriminal market.
Click to expand...

Although the PoS databases contain sensitive information, simply accessing them with the stolen passwords does not mean that payment card data is at risk.

PoS systems store the most important card data (numbers, expiration dates) in an encrypted form, which means that the attacker also needs a way to learn the passphrase that generates the database encryption key.

“This process would then have to be implemented into the module and – due to use of the Windows Data Protection API (DPAPI) – executed directly on the victim’s machine” - ESET

Ransomware gang says they stole 2 million credit cards from E-Land
December 3, 2020
https://www.bleepingcomputer.com/ne...hey-stole-2-million-credit-cards-from-e-land/

Clop ransomware is claiming to have stolen 2 million credit cards from E-Land Retail over a one-year period ending with last months ransomware attack.

However, in an interview with BleepingComputer, the CLOP ransomware operators claimed to have breached E-Land over a year ago and have been quietly stealing credit cards using POS malware installed on the network.

"Over a year ago, we hacked their network, everything is as usual. We thought what to do, installed POS malware and left it for a year. Before the lock, the cards were collected and deciphered, for a whole year the company did not suspect and did nothing," the CLOP gang told BleepingComputer.
Using the installed POS malware, CLOP told BleepingComputer that they stole the Track 2 data for 2 million credit cards over the past year.
Click to expand...

The stolen credit cards that CLOP claims to have stolen are in the form of Track 2 data, which includes a credit card number, the expiration date, and other information. It does not, though, contain a credit cards CVV code, so threat actors can only use it to create fake credit cards for in-store purchases.
