Stuxnet: The Revenge of Malware: How the Discovery of Malware from the Stuxnet Family Led to the U.S. Government Ban of Kaspersky Lab Anti-Virus Software

Duqu, the infamous malware from the Stuxnet family, made its return. First discovered in October 2011, Duqu was actively spying on digital certificate issuing authority in Hungary. As soon as it was exposed, the malware was abandoned by its originators. Information security companies added it to a “blacklist” database of anti-virus software.

Usually malware, after being detected, has no means of fighting back. It was not the case with Duqu. Two years after its exposure, the Duqu malware had its revenge. In 2017, the USA, UK, and some other European countries issued a ban on the use of Kaspersky Lab computer security software on their government and military computers. Their decision was based on information presented to them by the originators of the Duqu malware, which had been quietly stealing data from inside of Kaspersky Lab’s corporate computer network.
