A rather amateurish ransomware has been analysed by the Palo Alto Networks. The only interesting part is, that it is actually not asking for money, instead: "RanRan does not ask for direct payment. Instead, prior to any negotiations regarding payment, the victim must create a subdomain with a seemingly politically inflammatory name as well as a Ransomware.txt file hosted on this subdomain. The hosted file must include a statement of ‘Hacked’ and an email address. By performing these actions, the victim, a Middle Eastern government organization, has to generate a political statement against the leader of the country. It also forces the victim to publicly announce that they have been hacked by hosting the Ransomware.txt file."
