Hackers Could Be Probing Stock Exchange Network, Says Cybersecurity Firm

Many experts in the cybersecurity community, however, say they need more evidence before assuming a cyberattack was not involved.

The New York Stock Exchange (NYSE) may be at risk of a large-scale cyberattack, and the current narrative saying no attack is suspected is full of holes, according to the head of a cybersecurity firm.

Trading on the NYSE was suspended on Wednesday afternoon after an alleged glitch. Around the same time, United Airlines briefly grounded all flights due to a system-wide failure. The Wall Street Journal also went offline due to a problem with its computer servers.

Soon after the networks went offline, the NYSE stated on Twitter that the outage was “not the result of a cyber breach,” and the Department of Homeland Security said there was no indication that the NYSE had been hacked.
