| contents | The purpose of this study is to evaluate the possibility of implementing an attack on ALPC connection in the Windows operating system through the kernel without closing the connection covertly from programs and the operating system and to propose a method of protection against this type of attacks. Asynchronous Local Procedure Call technology (ALPC) is used in various Windows information protection systems, including antivirus systems (AV) and Endpoint Detection and Response systems (EDR). To ensure the concealment of malicious software, attackers need to disrupt the operation of AV, EDR tools, which in turn can be achieved by destructive impact on the components of the ALPC technology. Examples of such attacks already exist and are covered in this paper. To counteract such new threats, it is necessary to advance the improvement of information security systems and the ALPC security research was conducted. The most difficult case, Windows kernel driver attack, was considered. Three attacks on the ALPC connection were carried out, based on changing the ALPC structures in the kernel memory, which led to creation of illegitimate connections in the system and the disruption of correct connections. ALPChecker protection tool has been developed. The tool was successfully tested on three demonstrated attacks. |
