Colonial Pipeline resumed normal operations on Saturday after a ransomware attack forced the pipeline to shut down last week, the company announced.

Why it matters: The pipeline is now delivering fuel to states that had experienced gas shortages at the same capacities as before the extortion scheme hit the critical pipeline, which runs from Texas to New York and carries roughly 100 million gallons of fuel per day.

Context: Colonial Pipeline restored limited services on Wednesday but said it would take several days for the product delivery supply chain to return to normal.

What they're saying: "Our team members across the pipeline worked safely and tirelessly around the clock to get our lines up and running, and we are grateful for their dedicated service and professionalism during these extraordinary times," the company said.

  • "Colonial has and will continue to put safety and system integrity first and will invest the required resources to maintain safe and reliable operations of our pipeline."

According to crowdsourced data collected by GasBuddy, gas stations in 13 states and the District of Columbia were still experiencing fuel shortages as of 9:12 A.M. ET on Saturday

  • Patrick De Haan, a senior petroleum analyst at Gasbuddy, said in a tweet Thursday that it could take between two and 14 days for fuel services to be fully restored depending on the state.

The big picture: The hacker group DarkSide, which was responsible for the ransomware attack that shut down the pipeline, claims to be shutting down after it lost access to the infrastructure needed to carry out its extortion operations.

  • Yes, but: Security experts warn that cyber criminal groups often disband and return under different names, and it therefore can't be determined if the disruption to DarkSide's infrastructure is legitimate or permanent.

Gas stations in 12 states and the District of Columbia are still experiencing fuel shortages after Colonial Pipeline resumed service following a ransomware attack that caused the pipeline to shutdown, according to crowdsourced data collected by GasBuddy.

The state of play: Colonial Pipe said in a statement Wednesday it would take several days for the product delivery supply chain to return to normal following its restart.

DarkSide claims it's shutting down after Colonial Pipeline hack

The hacker group DarkSide, which was responsible for a ransomware attack that shut down the Colonial Pipeline and led to fuel shortages in multiple states this week, claims to be shutting down, Krebs on Security and several cybersecurity firms report.

Why it matters: In a message from a cybercrime forum, the group said it had lost access to the infrastructure needed to carry out its extortion operations and that a cryptocurrency account it uses to pay its affiliates had been drained.

Ireland's public health care service preemptively deactivated its IT services on Friday after it was targeted by a ransomware attack, according to the AP.

Why it matters: The attack on Ireland's Health Service Executive, and other recent high-profile cyber extortion attempts, demonstrates how vulnerable critical infrastructure is to criminal hacking groups.
