Confluence in Turmoil

The CVE-2023-22518 vulnerability in Atlassian's Confluence Server has allowed attackers to restore databases and execute malicious commands. The attackers seem to be enjoying a field day, with Ukraine being a favored target. While the party was short-lived for some IP addresses, our man on the inside, Glenn Thorpe, believes the exploits are still in full swing.

Just a Click Away

This cyber attack is a bit like a horror movie – just one click is all it takes to let the bad guys in. Screenshots from the DFIR report show data collected from these attacks. One particular group, calling itself C3RB3R (maybe they're big fans of the Muppets?), has been demanding ransoms.

The Weekend Attacks

Even weekends aren't safe from these cyber criminals! Security firms Rapid7 and Tenable reported a surge in attacks over the past weekend. Rapid7 even flagged this as a case of "mass exploitation" of on-premises Confluence servers.

Protect Your Confluence

The vulnerability is an improper authorization one and can be exploited on internet-facing Confluence servers. Atlassian's Chief Information Security Officer, Bala Sathiamurthy, has warned that this vulnerability could lead to significant data loss. In the words of the great Bala, "customers must take immediate action to protect their instances."

Atlassian's Plea

With the vulnerability now out in the open, threat groups are likely racing to exploit it before targets can patch up. Atlassian's senior management has been practically begging customers to patch for almost a week now. So folks, patch up or face peril!
