Seyfarth Shaw Targeted In Weekend Cyberattack, Firm Says (1)

Oct. 13, 2020, 3:57 PMUpdated: Oct. 13, 2020, 4:18 PM

AmLaw 100 law firm Seyfarth Shaw said it was hit over the weekend with a cyberattack that shut down its email system.

The firm’s email system was still down as of Tuesday morning, according to a bulletin posted on its website. The firm’s phone system wasn’t affected in the attack.

The Chicago-based firm said the malware attack, which struck on Saturday, appeared to be ransomware. Seyfarth said the “sophisticated and aggressive” hit was detected by its monitoring systems and that clients’ confidential information remains a top priority.

“We have found no evidence that any of our client or firm data were accessed or removed,” the firm said in its bulletin. “However, many of our systems were encrypted, and we have shut them down as a precautionary measure.”

Seyfarth said it’s working with the FBI to bring its systems back online, according to the bulletin. A firm spokesperson declined to comment beyond the initial bulletin.
