Researchers warn of a new ransomware family: a novel strain called Agenda sails in, targeting healthcare and education entities. Similar to another emerging piece written in Go language (aka Golang) dubbed BianLian, this cross-platform threat is gaining popularity with affiliates for its versatility and easy-to-tweak elements of the campaign, including encryption extension, personalized ransomware note (with the demanded ransom ranging from $50,000 to $800,000), and the embedded option for ransomware operators to choose which processes on the infected device to kill prior to encryption.

Agenda Ransomware Analysis
The in-depth research published by Trend Micro’s security analysts reveals that the studied pieces of targeted ransomware were 64-bit Windows PE files tailored to inflict maximum damage upon the chosen victims. The attacker also installed scanning programs like Nmap.exe and Nping.exe to map the network and used stolen credentials to access Active Directory using the RDP.
Researchers discovered that Agenda disables automatic login using the old login credentials and changes the default user’s password in order to remain stealthy. The strain uses techniques popular with other ransomware organizations, for instance, REvil or Black Basta, to reboot the victim’s computer in safe mode before encrypting files. The threat is designed for compromising the entire network, with adversaries using the double extortion technique to inflict more pressure on a victim to pay the ransom.
