Hotels in America are being targeted by cybercriminals in a campaign spreading a remote access Trojan (RAT) called NetWiredRC. The RAT is delivered via malicious emails targeting financial staff in hotels in North America.
The campaign uses a typical lure to get recipients to open the attached file. The message claims there are invoices outstanding and the recipient is asked to validate payment. The invoices are included in a zip file attached to the email.
If the file is extracted and the executable is launched, the Trojan will be downloaded by a PowerShell script. The Trojan achieves persistence by loading itself into the startup folder and will run each time the computer boots. The malware gives the attacker full control over an infected computer. Files can be uploaded and downloaded, further malware variants can be installed, keystrokes can be logged, and credentials can be stolen.
The ultimate aim of the threat actors behind this campaign is not known, although most cyberattacks on hotels are conducted to gain access to guest databases and payment systems. If malware can be loaded onto POS systems, card details can be skimmed when guests pay for their rooms. It can be months before hotels discover their systems have been breached, by which time the card details of tens of thousands of guests may have been stolen. Hutton Hotel in Nashville, TN, discovered in 2016 that its POS system had been infected with malware for three years.
There have been several recent cases of cyberattacks on hotels resulting in guest databases being stolen and sold on darknet marketplaces. The data breach at Marriott resulted in the theft of 339 million records and Huazhu Hotels Group in China experienced a breach of 130 million records.
Data breaches can prove incredibly costly. The cost of the data breach at Marriott could well reach $200 million, but even smaller data breaches can prove costly to resolve and can cause serious damage to a hotel’s reputation.
The latest spam campaign shows just how easy it is to gain a foothold in a network that ultimately leads to a 3-year data breach or the theft of more than 300 records: The opening of an attachment by a busy employee.
