These things make it an attractive target for cybercriminals and malicious actors. Cybersecurity researchers at Rapid 7 recently identified that hackers actively exploit the zero-day flaw to deploy ransomware.
Rapid7 MDR (Managed Detection and Response) detects Atlassian Confluence exploitation, including ransomware, targeting the following vulnerabilities that were disclosed in October 2023:-
On November 5, 2023, Rapid7 MDR began targeting Confluence Server exploitation. The process chain was similar across several contexts, indicating that assaults were likely to be prevalent.
Besides this, the POST requests in HTTP access logs were observed on both the following platforms:-
Following the first round of enumeration, the threat actors downloaded a malicious payload using Python Base64 instructions, which would have resulted in the deployment of Cerber ransomware.
StorageGuard scans, detects, and fixes security misconfigurations and vulnerabilities across hundreds of storage and backup devices.
Here below, we have mentioned all the fixed versions of Confluence:-
Atlassian Cloud users are safe from this issue; however, customers with vulnerable Confluence sites should update immediately and restrict external access for security.
