OilAlpha was more likely planning espionage activities as they used Remote Access Tools (RATs) like SpyMax and SpyNote to execute this phishing attack. Both the RATs SpyNote and SpyMax can be very harmful as they have the ability to access the device’s camera and audio, SMS data, call logs, network information, contact information, and GPS location data.
Not just the journalist and political representatives, the hackers’ group have also targeted non-governmental organizations that conduct or coordinated disaster response and human work in Yemen. OilAlpha has spoofed applications of organizations such as the Norwegian Refugee Council, the United Nations Children’s Emergency Fund, and the Red Crescent Society.

The report mentioned that there is still a lot more to find out to back up that back Yemeni operatives are behind the ongoing phishing campaign by OilAlpha. John Condra, Director of Strategic and Persistent Threats at Insikt Group said, “Uncertainly, it is difficult to determine if there has been any compromise of those assets and consequently, it is possible that foreign threat actors are utilizing them.”
He further stated that it is not clear yet that they are selling their infrastructure to other attackers and may be using it to target individuals of their interest. Outsiders like Iraqi Hezbollah, and Iranian and Lebanese hackers are favoring Islamic Revolutionary Guard Corps as they have a vested interest in the outcome of the civil war, which resulted in this threat.
