9-Month Data Breach Affects Millions of Wawa Customers

Last week, Wawa announced that millions of customers might have had their credit or debit card information stolen in a data breach impacting almost all of their store locations. According to the report, malware, which originated on March 4, was discovered on Wawa’s payment processing servers on December 10. As a result of the breach, Wawa is offering enrollment in a credit monitoring service, Experian Identity Works, free of charge.

Wawa’s CEO Chris Gheysens states that stolen information includes:

  • credit and debit card numbers,

  • expiration dates,

  • and cardholder names on payment cards.

Potentially all Wawa in-store payment terminals and fuel dispensers became compromised at different points.

If you have been to a Wawa sometime between March and December, monitoring your payment card account statements and checking your credit reports will help mitigate any potential fraudulent activity.

Cryptocurrency-Mining Botnet Uses a Taylor Swift Image to Hide Malware Payloads

A botnet, named MyKingz (also known as DarkCloud, Smominru, or Hexmen), is currently using an image of Taylor Swift to hide malware payloads which infect various devices over the internet.

MyKingz utilizes an internet scanning module that targets vulnerable hosts to gain an initial foothold on a victim’s device. Typically, the botnet abuses unpatched vulnerabilities in Telnet, SSH, RDP, and other software related programs; however, it’s now using steganography-based attacks.

Steganography is a tactic to hide malicious files inside of legitimate ones. According to Sophos, a UK-based security firm, MyKingz is hiding malicious EXE files inside of JPEG images of Taylor Swift. MyKingz uses this technique with the hopes of tricking security software on enterprise networks into only detecting a JPEG file download, rather than a malicious EXE file.

Cybercriminals have used other steganography-based attacks in the past, such as hiding EXE files in WAV audio files. The MyKingz attacks have proved successful as Sophos estimates it currently makes $300 a day, totaling over $3 million as of this writing.
