FBI investigators probing last year's cyber-attack on Nasdaq OMX have found out-of-date software, misconfigured firewalls and uninstalled security patches on the exchange operator's PCs, according to Reuters.
Last year hackers broke into Nasdaq OMX's Directors Desk, a Web-based service that lets management and board members of listed companies share confidential documents securely.
After detecting suspicious files in its systems, the operator called in the FBI's New York cyber-crime unit and US Department of Justice to investigate.
According to Reuters, citing sources, that investigation has found that Nasdaq OMX's basic computer architecture appears to have been sound, keeping hackers out of trading systems.
However, the ongoing probe has uncovered some sloppy practices, including old software, dodgy firewalls and uninstalled security patches, leaving bugs for attackers to exploit.
