A new wave of cyberattacks is targeting organizations that inadvertently expose Java Debug Wire Protocol (JDWP) servers to the internet, with attackers leveraging this overlooked entry point to deploy sophisticated cryptomining malware. Once a target is identified, the attacker initiates a JDWP handshake to confirm the service is active and then establishes a session, gaining interactive access to the Java Virtual Machine (JVM). By abusing JDWP, threat actors can not only deploy cryptominers but also establish deep persistence, manipulate system processes, and potentially pivot to other assets within the compromised environment. The attackers’ use of legitimate-sounding process names and system locations further complicates detection and remediation efforts, underscoring the need for vigilant configuration management and robust monitoring of exposed services. The script then sets up multiple persistence mechanisms, including modifying shell startup files, creating cron jobs, and installing a fake system service.

JDWP, a standard feature in the Java platform, is designed to facilitate remote debugging by allowing developers to inspect live applications. With years of experience under his belt in Cyber Security, he is covering Cyber Security News, technology and other news. However, when JDWP is left accessible on production systems—often due to misconfiguration or the use of development flags in live environments—it becomes a potent vector for remote code execution. The attackers demonstrated a high degree of automation and customization, deploying a modified XMRig cryptominer with a hardcoded configuration to evade detection. The stealthy nature of the payload, combined with its ability to blend in with legitimate system utilities, increases the risk of prolonged undetected activity and resource drain. Focusing on the infection mechanism, the attackers exploit JDWP’s lack of authentication to inject and execute shell commands directly through the protocol. This script is engineered to kill competing miners, download the malicious XMRig binary disguised as logrotate, and install it in the user’s configuration directory.

The attack flow typically begins with mass internet scans for open JDWP ports, most commonly port 5005. Notably, the malware used mining pool proxies to obscure the destination wallet address, complicating efforts to trace or disrupt the illicit mining operation. Wiz analysts identified this campaign after observing exploitation attempts against their honeypot servers running TeamCity, a popular CI/CD tool.
