After Reported Hacking, Nasdaq Found ‘Suspicious’ Files on Servers

After The Wall Street Journal reported late Friday that Nasdaq had been hacked, the exchange disclosed Saturday that it had found “suspicious files” on its servers, and that hackers could have affected its applications. The files have since been deleted.

Reuters reported that Nasdaq OMX did not give details on the hackers or on the object of their activities, saying only that there was no evidence that customer information was accessed or acquired, or that any of the trading platforms were accessed.

Adena Friedman, Nasdaq OMX’s chief financial officer, and Vince Palmiere, vice president of investor relations, said in a statement, "We continue to evaluate and enhance our advanced security controls to respond to the ever increasing global cyber threat and continue to devote extensive resources to further secure our systems.” They added, “Cyber attacks against corporations and government occur constantly.”
