Atlassian CISO Bala Sathiamurthy warned the public on November 3 about the bug, which he said could lead to “significant data loss if exploited.” The company escalated this on November 6, 2023 following evidence of malicious activity, including ransomware attacks.”

The Cerber ransomware operation was active between 2016 and 2019. Several ransomware experts said they had not seen the Cerber ransomware used in years.
