With new research this week warning that state-sponsored cyber attacks against financial systems are on the rise, the ShadowTalk team focus on one area of the financial services sector in particular: high-frequency trading (HFT). Richard Gold and Rafael Amado are joined by a guest HFT expert to discuss mergers and acquisition information, sharing insider secrets, and manipulating stock prices. The team look at what attacks are possible, what the consequences would be for the financial services industry at large, and why attacks against trading platforms and the industry itself have been so few and far between.
