RedCap Propose Change

Actor(s): OilRig

According to Trend Micro, this backdoor receives valid domain credentials as an argument and uses it to log on to the Exchange Server and use it for data exfiltration purposes. The main function of this stage is to take the stolen password from the argument and send it to the attackers as an attachment in an email. We also observed that the threat actors relay these emails via government Exchange Servers using vaild accounts with stolen passwords.
