Microsoft is warning of continuing attempts by nation-state adversaries and commodity attackers to take advantage of security vulnerabilities uncovered in the Log4j open-source logging framework to deploy malware on vulnerable systems.

"We have observed many existing attackers adding exploits of these vulnerabilities in their existing malware kits and tactics, from coin miners to hands-on-keyboard attacks."

Publicly disclosed by the Apache Software Foundation on December 10, 2021, the remote code execution vulnerability in Apache Log4j 2, aka Log4Shell, has emerged as a new attack vector for widespread exploitation by a variety of threat actors.

In the subsequent weeks, four more weaknesses in the utility have come to light - CVE-2021-45046, CVE-2021-45105, CVE-2021-4104, and CVE-2021-44832 - providing opportunistic bad actors with persistent control over the compromised machines and mount an evolving array of attacks ranging from cryptocurrency miners to ransomware.

Microsoft said it observed "Rapid uptake of the vulnerability into existing botnets like Mirai, existing campaigns previously targeting vulnerable Elasticsearch systems to deploy cryptocurrency miners, and activity deploying the Tsunami backdoor to Linux systems."

The development also comes as the U.S. Federal Trade Commission issued a warning that it "Intends to use its full legal authority to pursue companies that fail to take reasonable steps to protect consumer data from exposure as a result of Log4j, or similar known vulnerabilities in the future."
