Mutation testing for the agentic era
Tags: ai, api, authentication, blockchain, framework, guide, metric, open-source, risk, rust, skills, software, switch, tool, vulnerabilityCode coverage is one of the most dangerous quality metrics in software testing. Many developers fail to realize that code coverage lies by omission: it measures execution, not verification. Test suites with high coverage can obfuscate the fact that critical functionality is untested as software develops over time. We saw this when mutation testing uncovered…

Ethereum-Based EtherRAT, EtherHiding Power Stealthy Malware Campaigns
Hackers are abusing the Ethereum blockchain to hide and control a new Node.js backdoor called EtherRAT, using a stealthy technique known as EtherHiding to make their command”‘and”‘control (C2) infrastructure difficult to disrupt. EtherRAT, previously profiled by Sysdig and linked to North Korean “Contagious Interview” activity, is a Node.js backdoor that lets attackers run arbitrary commands,…
