We suggest to deploy an enterprise level malware and anti-virus solution on your system and network to handle threats like AgentTesla. A good anti-virus and malware blocker will be able to take care of the threat coming in from AgentTesla. It plants a keylogger on the attacked system and all the details of a remote user get shared with the attacker. Agent Tesla is a malware that seeks to steal financial data through the RAT or remote access trojan. We can see over 150 indicators of compromise over the past 4 days, as the malware seeks to target new hosts. You can read more about Cobalt Strike on AgentTeslaĪgentTesla is a malware that has been seen with an increased activity over the previous week, beginning September 20th, 2021. Cobalt Strike comes with a toolkit for developing shellcode loaders, called Artifact Kit.
It supports C2 and staging over HTTP, HTTPS, DNS, SMB named pipes as well as forward and reverse TCP Beacons can be daisy-chained. Beacon is in-memory/file-less, in that it consists of stageless or multi-stage shellcode that once loaded by exploiting a vulnerability or executing a shellcode loader, will reflectively load itself into the memory of a process without touching the disk. Beacon includes a wealth of functionality to the attacker, including, but not limited to command execution, key logging, file transfer, SOCKS proxying, privilege escalation, mimikatz, port scanning and lateral movement. One should take normal precautions to protect against threats emanating from a ransomware for Cobalt Strike.Ĭobalt Strike is a paid penetration testing product that allows an attacker to deploy an agent named ‘Beacon’ on the victim machine.
In the company of a ransomware group, Cobalt Strike could pose major ransomware threats to the corporate networks and assets.

It also doubles up for being used to place malwares, malicious payloads for remote code execution. For the uninitiated, Cobalt Strike is used by penetration testers to find vulnerabilities on corporate networks. More than 1000 instances of the Cloud strike servers have been traced by different security researchers in the current week, starting from 18.09.21. Cobalt strike servers have been found to be active since the last week.
