A joint CSA from the FBI, CISA, and ASD’s ACSC provides IOCs and TTPs of the Play ransomware group impacting businesses in North and South America and Europe. The group employs a double-extortion model, encrypting systems after exfiltrating data. Recommendations include multifactor authentication, offline backups, and system updates to mitigate ransomware incidents. They also encourage validating security controls. For more information, visit stopransomware.gov and report any incidents to the FBI or CISA.
From the meeting notes provided, I have generated the following clear takeaways:
1. The joint Cybersecurity Advisory (CSA) is part of the ongoing #StopRansomware effort to publish advisories for network defenders detailing various ransomware variants and threat actors.
2. The Play (also known as Playcrypt) ransomware group has impacted a wide range of businesses and critical infrastructure in North America, South America, and Europe since June 2022.
3. The Play ransomware group is known to employ a double-extortion model, encrypting systems after exfiltrating data, and their ransom notes do not include an initial ransom demand or payment instructions.
4. The FBI, CISA, and ASD’s ACSC encourage organizations to implement various mitigations detailed in the meeting notes, such as requiring multifactor authentication, maintaining offline backups of data, and keeping all operating systems, software, and firmware up to date.
5. The meeting notes also include recommendations for validating security controls and resources for mitigating ransomware attacks.
