WaterISAC regularly provides awareness of recent CISA reporting. While direct relevance to your utility/organization on the details of each report may vary, activity alerts like this are practical for general awareness and greater understanding of active threats and adversary capabilities.
Yesterday, CISA and the FBI released a joint Cybersecurity Advisory (CSA) #StopRansomware: Snatch Ransomware, which provides indicators of compromise (IOCs) and tactics, techniques, and procedures (TTPs) associated with the Snatch ransomware variant. FBI investigations identified these IOCs and TTPs as recently as June 1, 2023.
Since mid-2021, Snatch threat actors have consistently evolved their tactics to take advantage of current trends in the cybercriminal space and leveraged successes of other ransomware variants’ operations. Snatch threat actors have targeted a wide range of critical infrastructure sectors, including the Defense Industrial Base (DIB), Food and Agriculture, and Information Technology sectors. Snatch threat actors conduct ransomware operations involving data exfiltration and double extortion. After data exfiltration often involving direct communications with victims demanding ransom, Snatch threat actors may threaten victims with double extortion, where the victims’ data will be posted on Snatch’s extortion blog if the ransom goes unpaid. Snatch threat actors employ several different methods to gain access to and maintain persistence on a victim’s network. Snatch affiliates primarily rely on exploiting weaknesses in Remote Desktop Protocol (RDP) for brute-forcing and gaining administrator credentials to victims’ networks. In some cases, Snatch affiliates have sought out compromised credentials from criminal forums/marketplaces.
The reporting agencies encourage network defenders to review the CSA and apply the included mitigations to reduce the likelihood and impact of future ransomware incidents. See StopRansomware.gov for additional guidance on ransomware protection, detection, and response.
To report suspicious or criminal activity related to information found in advisory, contact your local FBI field office, or the FBI’s 24/7 Cyber Watch (CyWatch) at (855) 292-3937, or by e-mail at CyWatch@fbi.gov. If you have any further questions, or to request incident response resources or technical assistance related to these threats, contact CISA at CISAServiceDesk@cisa.dhs.gov.
