Colonial Pipeline is aware of unsubstantiated claims posted to an online forum that its system has been compromised by an unknown party. After working with our security and technology teams, as well as our partners at CISA, we can confirm that there has been no disruption to pipeline operations and our system is secure at this time.

Colonial Pipeline’s Previous Encounter with Ransomware

This isn’t the first time that a ransomware group has asserted they breached Colonial Pipeline. In May 2021, a group called DarkSide successfully infiltrated the company’s systems, resulting in significant operational disruption.

Colonial Pipeline chose to pay a ransom of 75 Bitcoin to the DarkSide ransomware gang on May 7, 2021, amounting to approximately $4.4 million at that time. The ransom was paid to regain access to their systems and expedite the resumption of operations.

In June 2021, the U.S. Department of Justice (DoJ) disclosed that it had seized $2.3 million in Bitcoin, which Colonial Pipeline had paid to the DarkSide ransomware gang. The seizure was made possible by tracing the cryptocurrency trail and identifying the wallets used to store the ransom.

Furthermore, the FBI successfully dismantled DarkSide’s infrastructure, leading to the complete downfall of the ransomware group. As of November 2021, the U.S. government offered a $10 million reward for substantial information on the DarkSide ransomware gang.

The 2021 ransomware attack on Colonial Pipeline remains one of the most high-profile incidents in the history of ransomware attacks, underscoring the threats posed to critical infrastructure. This event also reignited debates about the wisdom of companies paying ransomware demands.
