Krebs Stamos Ransomwhere Attack: A $32M Cybersecurity Nightmare

In August 2021, cybersecurity experts Brian Krebs and Alex Stamos published an alarming report on a massive ransomware attack that targeted dozens of companies in the U.S. and other countries. The attack, dubbed “Krebs Stamos Ransomwhere” by some in the industry, resulted in a total payout of $32 million by the affected companies. In this article, we will explore the details of the attack and its implications for cybersecurity in the future.

What Happened?

The Krebs Stamos Ransomwhere attack was a sophisticated and well-coordinated campaign that targeted companies using a popular remote access software called Kaseya VSA. Kaseya is a software company that provides IT management solutions to small and medium-sized businesses. The attackers exploited a vulnerability in Kaseya VSA to gain access to the networks of hundreds of its customers.

Once inside the networks, the attackers deployed a ransomware strain called REvil, which encrypted the files of the affected companies and demanded a ransom in exchange for the decryption key. The attackers demanded a payment of $70 million in Bitcoin, the largest ransomware demand on record. However, negotiations eventually led to a reduced payment of $32 million, which was made in exchange for the decryption key.


The Krebs Stamos Ransomwhere attack has several implications for cybersecurity in the future. Firstly, it highlights the need for better vulnerability management and patching practices. The attackers exploited a known vulnerability in Kaseya VSA, which had been identified and patched by the company earlier in the year. However, many of its customers had not yet applied the patch, leaving them vulnerable to the attack.

Secondly, the attack underscores the need for a comprehensive backup and recovery strategy. Many of the affected companies were forced to pay the ransom because they did not have adequate backups of their data. A robust backup and recovery strategy can help organizations recover from a ransomware attack without having to pay the ransom.

Thirdly, the Krebs Stamos Ransomwhere attack highlights the importance of cybersecurity insurance. The affected companies were able to recover some of their losses through insurance claims. Cybersecurity insurance can help organizations mitigate the financial impact of a ransomware attack and ensure business continuity.

Lessons Learned

The Krebs Stamos Ransomwhere attack serves as a wake-up call for organizations to take cybersecurity seriously. It demonstrates the need for a comprehensive cybersecurity strategy that includes vulnerability management, backup and recovery, and cybersecurity insurance. It also highlights the importance of keeping software and systems up-to-date and patching known vulnerabilities promptly.

In conclusion, the Krebs Stamos Ransomwhere attack is a stark reminder of the ever-increasing threat posed by ransomware attacks. It demonstrates the importance of being prepared and having a plan in place to mitigate the impact of such attacks. Organizations must take proactive steps to protect themselves from such attacks, or risk facing severe financial and reputational damage.
