A recent survey has revealed that almost half of the world’s security exchanges were targeted by cyber attacks last year. The reports said that almost 53 percent of exchanges had experienced a cyber attack last year that involved direct and indirect cost, each less than 1 million dollar.

According to the report, the most common forms were websites and other computer systems by overwhelming the targeted organizations networks with computer traffic, and viruses. Other forms of cyber-crimes reported by the exchanges included laptop theft, website scanning, data theft, and insider information theft.

The International Organization of Securities Commissions (IOSCO) research department and the World Federation of Exchanges Office have said that the attacks along with the interconnected nature of the markets have created the potential for widespread public mistrust. The survey found that the lack of widely available insurance against cybercrime add to the risk, as nearly four in five exchanges would have to bear the costs of a major attack themselves.
