Governments and major corporations worldwide are scrambling to see if they, too, were victims of a global cyberespionage campaign that penetrated multiple U.S. government agencies and involved a common software product used by thousands of organizations. The hack began as early as March when malicious code was snuck into updates to popular software that monitors computer networks of businesses and governments. The malware, affecting a product made by U.S. company SolarWinds, gave elite hackers remote access into an organization's networks so they could steal information. It wasn't discovered until the prominent cybersecurity company FireEye determined it had been hacked. Just because a company or agency uses SolarWinds as a vendor doesn't necessarily mean they were vulnerable to the hacking.
