This market spells dollar signs (or perhaps Bitcoin signs) for lower-level cybercriminals. “In this environment, IABs provide ransomware actors with a seemingly infinite pool of victims that are already compromised and thus merely require ransomware affiliates to deploy the malware.” “IABs have reached a significant level of success and notoriety in the past 18-24 months, given the parallel booming of the RaaS model,” he told Threatpost.

The business of gathering access to vulnerable organizations and then selling those to the highest bidder on the Dark Web has especially been on the rise as ransomware-as-a-service has grown in popularity, according to Stefano De Blasi, cyber-threat intelligence analyst at Digital Shadows. These big-game hunters use them for initial access in much larger attacks involving ransomware or business email compromise (BEC) hits, they added.Īnd indeed, the cyber-underground market for initial access brokers (IAB) is booming by all accounts. The goal has been to pilfer credentials and cookies, which the attacker can offer to more technically savvy cybercriminals, researchers said. “The actor also buys the crypters that allow the usage of such malware without being detected, throughout the years it has used several different cryptors, mostly bought on online forums… This shows that a small operation can run for years under the radar, while still causing serious problems for its targets.” Driven by an Initial Access Broker Boom “ doesn’t seem to be technically sophisticated, using off-the-shelf malware since the beginning of its activities without developing its own malware,” the researchers noted in a Thursday posting. The campaign can effectively be a bird strike to the business engine, so to speak, resulting in data theft, financial fraud or follow-on attacks, researchers said, who have uncovered new details about the perpetrators.Īccording to Tiago Pereira and Vitor Ventura at Cisco Talos, “Operation Layover” is likely the work of an unsophisticated threat actor based in Nigeria, which has been active on the cybercrime scene for at least six years in various campaigns against multiple sectors. A two-year-old espionage campaign against the airline industry is ongoing, with AsyncRAT and other commodity remote-access trojans (RATs) helping those efforts take flight.
