It also\u00a0attempts\u00a0self-deletion\u00a0and cleanup, which reduces forensic visibility\u00a0and increases recovery complexity while applying\u00a0TOR-based leak pressure\u00a0on victims.<\/p> <\/div> <div class=\"schema-faq-section\" id=\"faq-question-1770794808421\"><strong class=\"schema-faq-question\"><strong>What indicators should SOC teams\u00a0monitor\u00a0for\u00a0BQTLock\u00a0activity?<\/strong>\u00a0<\/strong> <p class=\"schema-faq-answer\">Key signals include\u00a0Remcos injection into\u00a0explorer.exe,\u00a0UAC bypass via\u00a0fodhelper.exe,\u00a0autorun persistence creation,\u00a0and\u00a0post-escalation credential theft or screen capture.
