UPCOMING PUBLIC ENGAGEMENTS WITH TALOS
Event: The Continuing Evolution of Ransomware @ InfoSec Europe, London Date: 2016-06-07 @ 11:20 Speaker: Martin Lee, Technical Leader Description: Cyber criminals are adept at maximising their profit from compromised machines. Criminals have developed botnets to monetise compromised devices, developed DDoS as a form of extortion racket, and created dark markets to trade stolen personal data. Ransomware allows criminals to bypass fluctuating levels of supply and demand in underground markets and to set a price for compromised data with the person who values it most, the victim. In this session, Martin will share how ransomware has evolved, the advantages of ransomware as a criminal business model, and how we can expect ransomware to develop in the near future.
