Rewterz Threat Alert – New Watering Hole Identified for Credential Harvesting

Severity

Medium

Analysis Summary

A Kuwaiti organization’s webpage used as an apparent watering hole. The webpage contained a hidden image which was observed between June and December 2019, and referenced domains associated with malicious activity conducted by the xHunt campaign operators. It is believed that the same threat actors involved in the Hisoka attack campaign compromised and injected this HTML code into this website in an attempt to harvest credentials from the website’s visitors; specifically, gathering account names and password hashes. It is yet to be confirmed but, it is possible that the actors intended to crack these hashes to obtain the visitor’s passwords or using the hashes gathered to carry out relay attacks to gain access to additional systems.

If successful in harvesting account credentials, the compromised data has a plethora of uses for the attackers and can allow them to breach an organization to steal sensitive information. Furthermore, because they’d be using trusted credentials, it can allow attackers to go undetected for long periods of time, enabling them to infiltrate other parts of an organization and even implement backdoors, like RATs, to get back into a system even after being removed. This can result in significant damage to an organization over a prolonged period of time.
