the group behind Trickbot, are building their own versions of Cobalt Strike, modified for their special needs and purposes. In many cases, leaked and older versions of Cobalt Strike are being used and in some cases, sophisticated threat actors, e.g. But why would a cybercriminal worry about such costs? Criminals who are using these tools do not just buy them from the vendors anyway.

License renewals cost $2,585 per user, per year. New Cobalt Strike licenses cost $3,500 per user for a one year license.

So how this usually goes, is an infection occurs, be it phishing, manual breaches by brute forcing a port, or even an exploit.В Once an endpoint has been compromised, the actor looks to compromise a server on the network.В There are numerous ways to accomplish this, in fact last year we saw the ZeroLogon vulnerability used against domain admin servers, which essentially gave full admin rights to a criminal within seconds!В Once the server is infected, Cobalt Strike is installed and itвЂ™s at this point, that more advanced network monitoring, vulnerability identification and a bunch of other advanced features, become available to the criminal.В Now armed with more capabilities, the attacker can more quickly and completely compromise endpoints across the network, eventually launching ransomware, sometimes after all the juicy data saved on the network has been collected and exfiltrated. Building out grip on the compromised network

After doing this, they can use Cobalt Strike to map out the network and identify any vulnerabilities as well as deploy implants, backdoors, and other tools to accomplish lateral movement eventually leading to complete network infection.

Those commands can include instructions to download malware. We have seen a significant uptick in these methods in 2020 and beyond.В As a follow-up to these more manual types of attacks, as opposed to spray-and-pray phishing attacks, we are seeing threat actors who have compromised a server, loading tools like Cobalt Strike Beacon onto the system.В Cobalt Strike Beacon provides encrypted communication with the C&C server to send information and receive commands. For example, by using brute force methods and exploiting vulnerabilities to break into networks. What we mainly see in the ransomware field is an increasing amount of manual infections. Lately, we have seen targeted attacks by both state-sponsored threat actors and ransomware peddlers. (The terms вЂњwhite hatвЂќ and вЂњblack hatвЂќ are also falling out of favor, as cybersecurity professionals adopt вЂњred teamвЂќ and вЂњblue teamвЂќ descriptors to describe offensive and defensive security teams.) Establishing a foothold These tools are meant to simulate intrusions by motivated actors, and they have proven to be very good at this.В So, while вЂњwhite hatвЂќ hackers were developing tools to more easily emulate вЂњblack hatвЂќ activities, few considered how these tools might be turned against someone. Cobalt Strike, and other penetration testing tools, were originally created for network defenders to train them to understand vulnerabilities and possible avenues of infection by cyber criminals. What is Cobalt Strike?Д¬obalt Strike is a collection of threat emulation tools provided by HelpSystems to work in conjunction with the Metasploit Framework. Cobalt Strike offers a post-exploitation agent and covert channels, intended to emulate a quiet long-term embedded actor in the targetвЂ™s network. Metasploit is notorious for being abused, yet modules are still being developed for it so that it continues to evolve.В Cobalt Strike is in the same basket. Metasploit-probably the best known project for penetration testing-is an exploit framework, designed to make it easy for someone to launch an exploit against a particular vulnerable target.

Maybe only Metasploit could give it a run for the first place ranking.

If you were to compose a list of tools and software developed by security and privacy defenders that ended up being abused by the bad guys, then Cobalt Strike would unfortunately be near the top of the list.
