If you are interested in exploring other examples of binaries not outlined in this post, more can be found in the LOLBAS project on GitHub, which we used as a reference resource and where much of our research for these templates is derived.Ītbroker.exe is a Microsoft Windows system executable file that stands for “Assistive Technology Manager Broker”. In addition, as a Breach and Attack Simulation solution, the steps and commands detailed are how the scenarios would be executed benignly within our platform and under our “do no harm” model. Please note that we have demonstrated the generalized adversary behavior in each example, but be mindful that the adversary may execute a slightly different variation than the ones that we have outlined below. In this post, we have captured a number of LOLBin behaviors to look out for, in hopes that detection engineers and SOC analysts will come to recognize the signs associated with these attacks and have a means for detecting the behaviors. ![]() Using the AttackIQ Security Optimization Platform, security teams can improve their cybersecurity readiness through continuous testing and security control validation, running assessments aligned to the MITRE ATT&CK framework against the total security program. To help organizations combat this risk, AttackIQ has released ATT&CK-aligned scenarios to test against LOLBins. LOLBins pose a growing threat that should not be taken lightly, and it is an organizational oversight if not monitored. On top of this, LOLBins are often fileless, and do not leave the tracks that foreign code or files typically leave behind. The day-to-day commonality of LOLBins inadvertently serve as a pseudo cloak of invisibility, allowing the attacker to act inconspicuously across the cyber kill chain and under the nose of SOC teams and intrusion detection tools. Specifically, LOLBins, or Living-Off-the-Land Binaries, are binaries local to the operating system and traditionally seen as non-malicious, but can be exploited beyond their supposed function by adversaries to accomplish their malicious goals. As adversaries continue to refine their approach with newer and more sophisticated methods to perform malicious activity, it is critical for detection engineers to stay up to date in the latest threat intelligence and adversary behaviors to monitor.
