A Trip to the Dark Site — Leak Sites Analyzed

Gone are the days when ransomware operators were happy with encrypting files on-site and more or less discretely charged their victims money for a decryption key. What we commonly find now is encryption with the additional threat of leaking stolen data, generally called Double-Extortion (or, as we like to call it: Cyber Extortion or Cy-X). This is a unique form of cybercrime in that we can

Cyber Threat Protection — It All Starts with Visibility

Just as animals use their senses to detect danger, cybersecurity depends on sensors to identify signals in the computing environment that may signal danger. The more highly tuned, diverse and coordinated the senses, the more likely one is to detect important signals that indicate danger. This, however, can be a double-edged sword. Too many signals with too little advanced signal processing just
