To mitigate the risks of ransomware attacks, companies should implement robust cybersecurity measures, such as maintaining offline backups of data, ensuring all backed-up data is encrypted, reviewing the security safeguards of third parties and vendors, and implementing policies that only allow systems to execute known and permitted programs. Additionally, organizations should have a secure recovery plan in place and retain multiple copies of sensitive information.


Recent Ransomware Attacks

The Recent Ransomware Attacks (RRA) site acts as a watchtower, providing you with near real-time ransomware tracking of attacks, groups and their victims. Given threat actors’ overarching, lucrative success so far, ransomware attacks have become the most ubiquitous, and financially and informationally impactful cyber threat to businesses and organizations today.

The site’s data is generated based on hosting choices of real-world threat actors, and a handful of other trackers. While sanitization efforts have been taken, we cannot guarantee 100% accuracy of the data. Attack updates will be made as source data is reported by reputable sources. By viewing, accessing, or using RRA you acknowledge you are doing so at your own risk.
