Cyberattacks surged during the summer of 2025, with ransomware groups targeting healthcare and retail sectors, while nation-state actors engaged in geopolitical cyber activities. Major incidents included the rise of the Interlock and Qilin ransomware groups, significant data breaches in retail, and the exploitation of Microsoft SharePoint vulnerabilities in a widespread campaign. Organizations are urged to improve their defenses by patching vulnerabilities, training personnel, and monitoring for lateral movement post-intrusion.

The FBI reported that the Play ransomware group has breached approximately 900 organizations as of May 2025, a significant increase from previous counts. The gang employs advanced tactics, including recompiled malware and threats to leak stolen data, while urging affected organizations to enhance their security measures, including implementing multifactor authentication and maintaining updated systems.

Around 8,000 children's names, pictures, and addresses have been stolen from the Kido nursery chain by a hacking group named Radiant, who are demanding ransom from the company. The breach has raised significant concerns regarding the safety of sensitive data related to children and has prompted responses from cyber-security experts and law enforcement.
