The FBI, Cybersecurity and Infrastructure Security Agency (CISA), and Australian Cyber Security Centre (ACSC) have issued a joint advisory revealing that the Play ransomware group (also known as Playcrypt) has compromised over 900 organizations globally as of May 2025. This marks a sharp increase from the 300 known victims in October 2023, underscoring the escalating threat posed by the group. The attackers have primarily targeted critical infrastructure sectors across North America, South America, and Europe, making this one of the most widespread ransomware campaigns in recent years.
Who Is Behind Play Ransomware?
First identified in June 2022, the Play ransomware group has quickly built a reputation for its aggressive and stealthy tactics. Operating under the alias “Playcrypt,” the group has cast a wide net, attacking a variety of sectors including healthcare, education, government, and utilities. Their global footprint and choice of targets indicate a highly organized and well-funded operation.
Attack Tactics and Techniques
One of the hallmarks of Play ransomware attacks is the use of recompiled malware for each victim. This tactic makes detection and analysis more difficult, allowing the attackers to evade many traditional cybersecurity defenses.
In addition to technical sophistication, Play is known for psychological warfare. They have been reported to directly contact victims, often via phone calls, to pressure them into paying ransoms, under threat of leaking sensitive data. This high-pressure tactic increases the urgency for victims, often forcing a payment decision within hours.
Exploiting Vulnerabilities: CVE-2024-57727 and Beyond
A significant vector of attack for the Play group has been the exploitation of known vulnerabilities, most notably CVE-2024-57727. This flaw affects SimpleHelp, a widely used remote monitoring and management (RMM) tool. Researchers warned earlier in the year that more than 3,400 SimpleHelp instances were exposed online, creating a large attack surface. Initial Access Brokers (IABs) working with Play have leveraged this and other vulnerabilities to gain unauthorized access to networks.
Who’s at Risk?
While major infrastructure entities remain top targets, small and medium-sized businesses are also at risk. Many of these businesses lack robust cybersecurity defenses, making them easy prey for sophisticated ransomware groups. Industries relying heavily on legacy systems or exposed RMM tools are especially vulnerable.
Recommended Defensive Measures
The joint advisory outlines several steps organizations can take to mitigate the risk:
- Apply all available updates and patches promptly to eliminate known vulnerabilities.
- Implement Multi-Factor Authentication (MFA) across all systems, especially for remote access services like VPNs and webmail.
- Segment networks to limit the spread of ransomware and isolate critical data.
- Monitor for Indicators of Compromise (IOCs) associated with Play ransomware.
- Report incidents to the FBI or CISA to aid in tracking and neutralizing threats.

Broader Implications
The Play ransomware campaign shows us the growing sophistication of cybercriminal operations. With tactics that blend advanced malware engineering and psychological manipulation, groups like Play are elevating the stakes in the global cybersecurity landscape.
The rise in incidents also reflects a broader trend toward cybercrime-as-a-service (CaaS), where specialized roles such as malware development, access brokerage, and ransom negotiations are outsourced, making it easier for these groups to scale attacks rapidly.
Final Thoughts
The breach of over 900 organizations by Play ransomware is not just a statistic. It’s a wake-up call for businesses, governments, and cybersecurity professionals. Vigilance, proactive defense, and swift reporting are essential to staying ahead of these evolving threats. With ransomware campaigns growing in frequency and intensity, the time to act is now.
