All of Epiq’s systems are officially up and running again. The e-discovery and managed services company had taken its global systems offline in late February after detecting “unauthorized activity” that an investigation later revealed to be a “Ruyk” ransomware protocol attack. 

According to a statement posted to the company’s website on Thursday, the cybersecurity firm Mandiant found no evidence that any client data was accessed or exfiltrated. “There has been no evidence of malicious activity in our system since March 1, 2020, and the attack did not impact our backup systems or data,” read the statement.
