Attack Overview
The Meow ransomware group has claimed responsibility for the attack on Diamcad via their dark web leak site. The group alleges that they have exfiltrated over 120 GB of sensitive data from Diamcad's systems. To substantiate their claims, Meow has posted sample screenshots of the stolen data, increasing the pressure on Diamcad to respond to the breach.
About Meow Ransomware Group
Meow Ransomware emerged in late 2022 and is associated with the Conti v2 ransomware variant. The group resurfaced in late 2023 and has been highly active in 2024. Meow Ransomware primarily targets industries with sensitive data, such as healthcare and medical research. They employ various infection methods, including phishing emails, exploit kits, Remote Desktop Protocol (RDP) vulnerabilities, and malvertising.
Once a system is compromised, Meow Ransomware encrypts files using a combination of the ChaCha20 and RSA-4096 algorithms. The group leaves behind a ransom note named "readme.txt," instructing victims to contact them via email or Telegram to negotiate the ransom payment. Security researchers have identified the threat actors behind Meow Ransomware as the "Anti-Russian Extortion Group," likely due to their targeting of entities in response to the Russia-Ukraine war.
Potential Vulnerabilities
Diamcad's reliance on advanced technology and digital systems for diamond assessment and processing may have made them a target for ransomware groups like Meow. The company's significant turnover and high-value assets further increase its attractiveness to cybercriminals. The attack highlights the importance of stringent cybersecurity measures, especially for companies operating in high-stakes industries like diamond manufacturing.
