is a Windows-based ransomware operation known as Rhysida that has gained prominence since May 2023. It has been linked to high-profile cyber attacks across Western Europe, North and South America, and Australia. Rhysida is believed to have connections with the notorious Vice Society ransomware gang. The group has targeted various organizations, including hospitals and clinics in the United States and even the Chilean Army. The ransomware group gets its name from a type of centipede, which is reflected in the images used on its leak website. Rhysida leaves behind PDF files in affected folders as a sign of compromise. The ransom note, disguised as a “critical breach” alert from the Rhysida “cybersecurity team,” warns victims of potential data sale or distribution. To obtain a decryption key, victims must visit the group’s dark web portal and pay a ransom in Bitcoin. Despite the seemingly polite tone of the ransom note, the group has already caused significant reputational and financial damage to its victims. The real threats posed by Rhysida include the loss of data, the need to negotiate with the attackers, and the potential damage to a company’s brand and relationships. The group typically gains access to organizations through phishing attacks, emphasizing the importance of following best practices to protect against ransomware.
