Before cybercriminals can steal sensitive data, they need unauthorized access to an organization’s systems and networks. As Ransomware-as-a-Service (RaaS) models evolve the threat landscape, initial access brokers (IABs) help threat actor groups selling ransomware by supplementing the malicious technology infrastructure with the access necessary to deploy the attack. Security teams defending against these attacks need a layered defense that considers all the different criminal entities involved in modern-day attacks.
By understanding what initial access brokers do and how they fit into RaaS models, security teams can improve their monitoring and detection capabilities.
What are Initial Access Brokers (IABs)?
Initial access brokers (IABs) are cyber threat actors who specialize in compromising networks so they can sell the access in underground forums across the dark web and illicit Telegram channels. IABs are often highly sophisticated and specialized threat actors who gain access to highly sensitive IT infrastructure.
IABs focus on gaining unauthorized access to networks by using various techniques, including:

As organizations adopt more cloud-native technologies, compromising networks becomes more lucrative for malicious actors who specialize in gaining initial access. According to the MITRE ATT&CK Framework, initial access consists of the various techniques that attackers use when trying to gain a foothold within a network that later allows them to compromise sensitive data. As specialists, IABs create a business model focused on selling this access to other threat actors.
