Background for this topic.
Malicious code is software, a script, or an altered program intended to perform unauthorized or harmful actions on a device or network. The term includes malware such as viruses, worms, trojans, spyware, and ransomware, as well as harmful macros or commands. Depending on its function, it may exploit a software weakness, execute with a user’s permissions, disrupt availability, or modify, destroy, or collect data.
Security teams should treat malicious code as both a prevention and detection concern: keep operating systems and applications patched, restrict unnecessary scripting and privileges, and use endpoint controls that identify unusual execution or persistence. Network and host telemetry can support investigation, while isolation and recovery from known-good backups can limit damage after execution. Analysis of samples and indicators can also guide threat intelligence and vulnerability-management priorities, but suspected code should be handled carefully to avoid executing it on production systems or exposing collected data.
A now-fixed vulnerability in the open-source vulnerability scanner Nuclei could potentially allow attackers to bypass signature verification while sneaking malicious code into templates that execute on local systems. [...]

A high-severity security flaw has been disclosed in ProjectDiscovery's Nuclei, a widely-used open-source vulnerability scanner that, if successfully exploited, could allow attackers to bypass signature checks and potentially execute malicious code
News has been making headlines over the weekend of the extensive attack campaign targeting browser extensions and injecting them with malicious code to steal user credentials. Currently, over 25 extensions, with an install base of over two million users, have been found to be compromised, and customers are now working to figure out their exposure (LayerX, one of the companies involved in
A new attack campaign has targeted known Chrome browser extensions, leading to at least 16 extensions being compromised and exposing over 600,000 users to data exposure and credential theft
