RPost RAPTOR AI Cleans Up After Dark Use of Mythos-Esque AI AgentsRPost RAPTOR AI Thwarts Cybercriminal Recon on $5.5 Billion of Q1 Deals in 12K Businesses.

April 16, 2026 – Los Angeles, CA

RPost announces limited availability of its RAPTOR™ Intelligence Report that maps cybercriminal tactical trends discovered in 11,513 unique business and 2,256 unique self-directed investor compromises in the midst of estimated $5.5 billion of aggregate financial transactions(1). These activities are supported by distributed data indicator breadcrumbs spanning 146 countries, underscoring both the geographic scale and the diffuse nature of the threat landscape.

RAPTOR AI by RPost identified these businesses -- insurance, escrow, law, title, real estate, private equity, banks/lenders, and self-directed investor buyers and sellers -- under active cybercriminal surveillance in the days leading up to transaction closure and contributed to preempting wire fraud, invoice fraud, BEC and other financial crimes. RPost was recently named a Visionary by Gartner Research® in its Impact Radar Report in the Pre-Crime Preemptive Cybersecurity category and named in the Gartner Research® Magic Quadrant™ for Email Security Platforms.

The RAPTOR Intelligence Report identifies recent cybercriminal tactical trends and delves into detailed case studies of three cybercriminal attacks building via compromised third-party accounts involving email and file share/data room threads:

  1. Emerging evasion tactic: blending into security scanner traffic         
  2. Emerging cross-border tradecraft: multi-actor recon/handoffs       
  3. Late-stage pre-crime: third-party file-share leak & context trove

“Anthropic, with its newly announced Mythos model, made mainstream a dark secret that many cybersecurity specialists have known --- AI agents can be unleashed by nefarious cabals to seek vulnerabilities at the speed, scale and with the intelligence that no human cybercriminal cabal was capable of in the past,” states RPost CEO Zafar Khan. “What is new is the pace of change in terms of boost in AI agent intellect and creativity to find new paths to compromise systems at scale. It’s now an AI arms race, AI security for the good guys must keep pace with AI deployments by the bad guys. This is where RPost RAPTOR™ AI becomes a unique and essential counter-insurgence tool.”

The RAPTOR Intelligence Report analyzes approximately 500 million RAPTOR AI agent data security activities conducted by RPost systems in Q1 2026 and uncovers approximately 13,769 third party businesses and self-directed investors related to financial services transactions under Suspected Unexpected Serious Adversarial Reconnaissance (SUSAR). 

“We expect the number of compromised third parties to skyrocket in coming months due to the inevitable cybercriminal use of Mythos or its lookalikes,” adds Khan. “RAPTOR™ AI sees the otherwise unseen and can then agentically un-leak leaks that would otherwise provide cybercriminals rich context to generate juicy phishing lures or worse.”

The Report describes the current state of “modern” man-in-the-middle attacks with use case examples of RPost RAPTOR™ AI seeing beyond endpoints to view active cybercriminal recon (two different examples) with a third example of later stage post-recon, pre-crime document file share link (data room) compromise designed to maximize cybercriminal context. 

RAPTOR™ AI adds an entirely unique preemptive, offensive cybersecurity approach compared to the other things in the email and document security ecosystem. Aragon Research named RPost a Pioneer in a category it is naming Preemptive Intelligent Content Security, in part due to its RAPTOR™ AI cybersecurity overlay on its RMail, RSign, RForms, RDocs, and Registered Email content platforms for email security, file share, email compliance, document rights, eSignatures and forms workflows (access Aragon Research topical research note).
