The malware too uses an NSA tool known as ‘ EternalBlue ’ for proliferation, according to a report in Fortune. The report added that EternalRocks uses six other NSA tools, including EternalChampion, EternalRomance, and DoublePulsar , which is a part of the infamous ‘ WannaCry ’.

A "critical" patch had been issued by Microsoft on 14 March 2017 to remove the underlying vulnerability for supported systems, nearly two months before the attack, but many organizations had not yet applied it. Those still running exposed older, unsupported op
