(Reuters) - The hackers who caused Colonial Pipeline to shut down on Friday began their cyberattack against the top U.S. fuel pipeline operator a day earlier and stole a large amount of data, Bloomberg News reported citing people familiar with the matter.
The attackers are part of a cybercrime group called DarkSide and took nearly 100 gigabytes of data out of Colonial's network in just two hours on Thursday, Bloomberg reported https://www.bloomberg.com/news/articles/2021-05-09/colonial-hackers-stole-data-thursday-ahead-of-pipeline-shutdown?sref=SCAzRb9t late Saturday, citing two people involved in the company's investigation.
