A decade ago, ransomware actors demanded ransom payment through a premium-rate SMS number. The emergence of cryptocurrency drastically changed the game in when merchants started using bitcoin as a form of payment , and that trend has continued until now. Another shift is in the method of collaboration and communication between underground actors. There are different platforms being used : forums, messengers, and sometimes even social media.

New security and anonymization features of these platforms improved the capability of these actors to covertly collaborate online. One example of cybercriminal collaboration is ransomware as a service RaaS , which helped actors find affiliates to carry out ransomware attacks. Instead of just one ransomware group doing all of the work, several collaborators split roles and profits.

The evolution of these affiliate programs allowed for more effective monetization of compromised assets, which was profitable for all parties involved. When ransomware actors used automated tools, the ransom amount was either fixed or set by the attacker during negotiation with the victim. In more modern attacks, the actor has a substantial amount of information about the victim, allowing for more tailored ransom pricing. The whole attack chain often involves two or more groups who are responsible for the different attack stages.

The attack typically involves the actor who owns the ransomware, and another actor who controls the compromised infrastructure and distributes malware over a network. Since it is normal for this market to have a ransom for big organizations in the seven-digit range , attackers may be able to afford more expensive tools like zero-day local privilege escalation LPE and remote code execution RCE exploits. Multiple cybercriminal groups now often operate together, sharing access and following parallel monetization lifecycles.

This can be very confusing for the defender who may not be aware that they are looking at traces coming from several groups, which can be related to many parallel — and even unrelated — incidents. The prevalence of these sophisticated ransomware attacks means a shorter reaction time and a much higher potential impact.

However, new technologies are also available for cybercriminals to add to their arsenal. Also, vulnerabilities in much-used devices and platforms on the network perimeter are big risks for enterprises — many threats use these weaknesses as entry points into a network. This shift toward a more targeted criminal monetization scheme is due to several key factors, including:. This shift means deep victim profiling has been performed before an attack is initiated, followed by a collaboration among multiple groups who are sharing accesses and using optimized monetization strategies.

This section will use the Nefilim ransomware family as an example of a modern ransomware attack. After gaining initial access, Nefilim attackers start by downloading additional tools on a web browser. One significant download is a Cobalt Strike beacon that is used to establish a remote connection to the environment and execute commands.

Cobalt Strike is a versatile post-exploitation penetration tool that allows security testers to attack the network, control the compromised system, and exfiltrate interesting data. Unfortunately, its capabilities can be misused by attackers. Other downloaded files are: the Process Hacker tool, which is used to terminate endpoint security agents ; and Mimikatz , which is used to dump credentials. Attackers move laterally once they gain a foothold into the network, meaning they will use a compromised system to find other areas they can access.

Attackers can deploy tools within systems to aid in lateral movement. Cybercriminals can abuse tools like AdFind to collect Active Directory information and map out the infrastructure to find more targets. Attackers can exploit known vulnerabilities to elevate privileges and perform administrative actions or actions requiring elevated privileges. The actors have a preference for hosting companies in various countries including Bulgaria, the UK, the US, and the Netherlands.

We observed Nefilim actors making use of at least three different kinds of bulletproof hosting services: a Tor-hidden server that is used to leak stolen information, small IP ranges belonging to small shell companies, and fast flux hosting hosting where the frontend regularly changes its IP address.

Once it is running, the execution flow is very straightforward. First, Nefilim creates a mutual exclusion mutex object to prevent more than one thread of the same process. Then, it will decrypt the ransom note using a fixed RC4 key. Figure 2 shows an example of the ransom note, which includes three email addresses that victims can use to contact the Nefilim actors about the ransom payment.

It then generates a random AES key for each file that it queues for encryption. National Geographic. National Geographic Wild. Viasat History.
