Organizations and individuals are caught in the crosshairs of the burgeoning malware attack trends. A new malware loader dubbed Verblecon managed to stay under the radar for around a year only to be discovered now. Researchers uncovered the malware recently in a campaign that was used to install cryptocurrency miners on infected machines. In another instance, VMware Horizon servers vulnerable to Log4Shell vulnerability were found being exploited to deploy a backdoor named Sliver, and four miners - z0Miner, JavaX miner, Jin, and Mimu.

Furthermore, nearly 800 malicious npm packages have been found in a large-scale software supply chain attack to target developers. The packages are used by the RED-LILI threat actor to evade detection.

Top Malware Reported in the Last 24 Hours

Newly discovered Wslink loader
Researchers have discovered a new Wslink malware loader that runs as a server and executes modules in memory. The malware makes use of process virtual machine as part of its obfuscation process.

Sophisticated Verblecon loader
A newly discovered malware loader, dubbed Verblecon, is being used to install cryptocurrency miners on infected machines. Despite being around for more than a year, the malware sample is able to maintain a low detection rate due to the polymorphic nature of the code. Researchers claim that cybercriminals may use the loader in the future to disseminate ransomware and even launch espionage attacks.

Backdoor and miners detected
Researchers are warning that the Log4Shell vulnerability is being actively exploited to deliver backdoors and cryptocurrency miners onto vulnerable VMware Horizon servers. The campaign leverages remote monitoring software packages, Atera or Spashtop, and the backdoor detected is Sliver. The four miners are z0Miner, JavaX miner, Jin, and Mimu.

Software supply chain attack campaign
A threat actor dubbed RED-LILI has been linked to an ongoing large-scale supply chain attack campaign that targets the NPM package repository. Researchers found nearly 800 malicious packages that were published in the repository via a fully-automated system that enabled the attacker to bypass the verification process.

Top Vulnerabilities Reported in the Last 24 Hours
