Incident Details
A recently identified ransomware group called BlackSuit, bearing resemblances to the Royal ransomware family, poses a significant threat to the Healthcare and Public Health (HPH) sector. Unveiled in early May 2023, BlackSuit shares striking similarities with Royal, which succeeded the infamous Conti ransomware group associated with Russia. These parallels position BlackSuit as one of the prominent active ransomware groups currently operating. Both Royal and the now-defunct Conti have historically targeted the HPH sector aggressively. If the alleged connections to BlackSuit are confirmed, the sector is likely to face continued severe attacks. This overview delves into the characteristics of the potential new group, potential affiliations with other threat actors, an assessment of its ransomware campaigns, target industries and affected countries, impact on the HPH sector, employment of MITRE ATT&CK techniques, indicators of compromise, and recommended defense strategies. BlackSuit adopts a double extortion tactic by stealing and encrypting sensitive data within compromised networks. Incidents of BlackSuit ransomware use have been observed in limited attacks. A recent suspected attack in October 2023 targeted a U.S.-based HPH entity, encrypting its servers and systems with the presumed BlackSuit malware. Several cybersecurity firms have reported multiple attacks involving the BlackSuit encryption tool, with ransom demands under $1 million. These attacks span various sectors such as manufacturing, business technology, business retail, and government in the United States, Canada, Brazil, and the United Kingdom. Despite a small number of known victims, the ransomware group garners attention due to its alleged ties to the prolific Royal ransomware family. Confirmation of these associations would elevate BlackSuit to a notable threat actor warranting close monitoring in the coming days. Access the complete analyst report at HHS (pdf).

Summary of Coverage
The BlackSuit ransomware, which surfaced in 2023 and shares similarities with the Royal ransomware group, poses a significant risk to the Healthcare and Public Health (HPH) industry. Linked to the infamous Conti group, BlackSuit has focused on a small set of targets across the U.S., Canada, Brazil, and the UK, employing a tactic of double extortion to hijack and encrypt data. Although the number of attacks is low, its association with Royal has the potential to increase its level of danger. Key defensive strategies involve implementing strong cybersecurity protocols, keeping systems updated, creating data backups, and conducting training to recognize phishing attempts.
