[QUOTE="Andy Ful, post: 953053, member: 32260"] Here is an example of rare malware that was not created directly for profit but was intended to destroy the victims' systems (Iranian trains). The attack was directed against the Iranian government. The attackers managed to obtain high privileges on the victim's domain server, placed there a batch file (setup.bat), and created a task scheduler by Group Policy to execute this file. The original article about this attack can be found on the Padvish Malware Threats Database (Iranian AV): [ATTACH]259922[/ATTACH] [URL unfurl="false"]https://threats.amnpardaz.com/malware/trojan-win32-breakwin/[/URL] [URL unfurl="false"]https://labs.sentinelone.com/meteorexpress-mysterious-wiper-paralyzes-iranian-trains-with-epic-troll/[/URL] [URL unfurl="false"]https://malwaretips.com/threads/new-destructive-meteor-wiper-malware-used-in-iranian-railway-attack.109331/[/URL] On this infection stage, the attackers could disable Defender, but they choose another way: [LIST] [*]Disabled network and logged off from Active Directory. [*]Added Windows Defender exclusions to prevent the malware from being detected. [/LIST] These actions were possible due to remote management with high privileges which is an important infection vector in organizations and does not occur in the Home environment. It is worth mentioning that the attackers invalidated Defender after compromising the server, so the network was already seriously compromised (probably via lateral movement). [/QUOTE]
