Knight Ransomware Group's Attack on Crace Medical Centre
Knight ransomware group claimed an attack against Crace Medical Centre. The group obtained 30GB of confidential corporate data. Crace Medical Centre provides medical care in Crace and aims to provide personalized, quality patient care.
Knight Ransomware Emergence
Knight ransomware first came to attention in July when the group overhauled the interface and code of the Cyclops ransomware. As part of their operation, they continue to recruit affiliates through the RAMP hacking forum to enhance their ability to steal data from both Windows and Linux systems. In addition to their regular encryptors, the Knight ransomware operation offers a 'lite' version suitable for spam, spray-and-pray, and batch distribution campaigns.
Deceptive Recruitment Tactics
The Knight ransomware gang employs an HTML attachment labeled 'TripAdvisor-Complaint-[random].PDF.htm,' which redirects users to a deceptive web browser interface impersonating TripAdvisor. Within this simulated browser window, users are prompted to review a restaurant complaint, but it is, in fact, a ruse. When users click on the 'Read Complaint' button, an Excel file titled 'TripAdvisor_Complaint-Possible-Suspension.xll' is downloaded onto their system. This download subsequently triggers the activation of ransomware.
Ransomware Encryption Process
The Knight Lite ransomware encryptor, injected into a new explorer.exe process, is utilized to encrypt files on targeted computers. Following encryption, the encrypted files' names are appended with the '.knight_1' extension, where '1' indicates the lite version. Subsequently, the ransomware generates a ransom note in each folder on the compromised computer, demanding a payment of $5,000 to be sent to a provided Bitcoin address.
Recent Ransomware Attacks
The Recent Ransomware Attacks (RRA) site acts as a watchtower, providing you with near real-time ransomware tracking of attacks, groups and their victims. Given threat actors’ overarching, lucrative success so far, ransomware attacks have become the most ubiquitous, and financially and informationally impactful cyber threat to businesses and organizations today.
The site’s data is generated based on hosting choices of real-world threat actors, and a handful of other trackers. While sanitization efforts have been taken, we cannot guarantee 100% accuracy of the data. Attack updates will be made as source data is reported by reputable sources. By viewing, accessing, or using RRA you acknowledge you are doing so at your own risk.
