Elastic Security Labs reported Shellter Elite being abused in malware delivery campaigns due to a leaked license.
Shellter Project released a patch to address the incidents and prevent future abuse of the commercial pentesting tool.
The tool designed for ethical red team operations was used to deploy infostealers and bypass antivirus and EDR defenses.
The Shellter Project criticized Elastic Security Labs for not notifying them earlier and vowed to distribute the newest version only to vetted customers.
