Government agents seized control of two computer networks that are used by hackers to steal banking information and lock files on infected computers, officials in the United States and Europe said Monday, disrupting the circulation of two of the world’s most pernicious viruses, which have infected millions of computers worldwide.
The coordinated strike targeted malware known as GameOver Zeus, which is known to steal bank information and send it to overseas hackers, and CryptoLocker, which burrows into computers and encrypts personal data. The hackers then demand a ransom to unlock the files.
