The Cold Structure of the Cyber Underground Economy Where ''Attackers Who Downloaded Attack Tools'' Become Victims
A hacking campaign targeting hackers was identified. Cybereason Nocturnus analyzed a large-scale campaign where njRat remote access trojan (RAT) was embedded in multiple hacking tools and cracked files. Attackers uploaded malware-infected tools to hacking forums and websites and took control of PCs of users who downloaded them. The paradox: people seeking illegal tools to hack others were caught in the traps of more sophisticated attackers, losing their own systems. "Even among thieves, there is no honor." Core mechanism: njRat embedded in SQLi Dumper and other penetration testing/hacking tools, cracks, keygens, and installers; users download believing they''re getting a functional tool; malware installs silently while the legitimate tool functions normally. njRat capabilities: keylogging; screenshot capture; file manipulation and exfiltration; webcam/microphone recording; essentially complete attacker control of the infected system. Disguise technique: njRat samples used legitimate Windows process names (explorer.exe, svchost.exe) but actual execution paths were non-standard (%AppData% subdirectories) — the telltale sign visible in the execution path and missing code signatures. Infection impact: not just novice script kiddies but experienced hackers seeking advanced tools were victimized — the campaign targeted the "hacker community" specifically because those users have above-average technical access and data on their systems. The structural cyber underground economy insight: the supply chain for hacking tools has become predatory — tool providers inject malware knowing their customers cannot complain to authorities; the implicit social contract of the hacker underground (tools work as advertised, payment optional) is broken by attackers who see their "customers" as targets. Defense recommendations: security teams should monitor for hacking tool usage on corporate networks (indicating insider threat or compromised systems); endpoint detection for process name spoofing (legitimate names in non-standard paths); organizational policies addressing shadow IT and unauthorized software downloading.
