“thedarkoverlord” Targets Finance in Next Wave of Extortion Attacks


Key Findings 

  • On September 25, 2016, “thedarkoverlord,” a notorious threat actor behind the recent extortion attempts of several healthcare organizations, gained access to highly-sensitive information from WestPark Capital investment firm.
  • The CEO of WestPark Capital refused the actor’s blackmail demands, and as a result, partial information was released to the public by thedarkoverlord
  • Flashpoint identified 13 affected organizations across multiple industries.
    Based on publicly-available information, at least 35 organizations could be affected by the breach.



Based on a statement released by actor “thedarkoverlord” (also known as “TheDarkOverlord”) via the actor’s Pastebin site, Richard Rappaport, CEO of Los Angeles-based WestPark Capital, a full-service investment firm, became the thedarkoverlord’s most recent extortion victim and is refusing to pay off the criminal.

In an attempt to “persuade” the non-complying CEO to pay an undisclosed ransom payment, thedarkoverlord released a small batch of files pertaining to a variety of the firm’s current and previous business partners. thedarkoverlord’s statement includes the following explanation:

we are releasing a select few documents belonging to WestPark Capital located in the Los Angeles, California, United States area. WestPark Capital is a “full service investment banking and securities brokerage firm” whose CEO, [redacted] spat in our face after making our signature and quite frankly, handsome, business proposal and so our hand has been forced.
