Security companies have reported that threat actors and researchers have actively scanned and exploited the Atlassian Confluence vulnerability.

The news comes just days after researchers publicly released a technical write-up on the vulnerability.

The Confluence Remote Code Execution vulnerability, known as CVE-2021-26084, allows an unauthenticated attacker to remotely execute commands on a vulnerable server.

While the cybersecurity intelligence company Bad Packets had used threat actors from different countries to download and execute PowerShell or Linux shell scripts, the investigation shows that the attacks are mainly to mine cryptocurrencies.

There are some additional concerns that the exploit could also be used for advanced attacks, including spreading the efforts through a network ransomware attack and data exfiltration.

Organizations running a Confluence Server are advised to install the latest updates as soon as possible.
