One such example is a tool dubbed AuKill by Sophos discussed here. However, this tool uses many of the techniques covered in this blog and includes many of the same detection opportunities.The AuKill tool abuses an outdated version of the driver used by version 16.32 of the Microsoft utility, Process Explorer, to disable EDR processes before deploying either a backdoor or ransomware on the target system.The method of abusing the Process Explorer driver to bypass EDR systems isn’t new; it was implemented in many open-source tools. AuKill possibly uses multiple code snippets from, and built their malware around, the core technique introduced by Backstab. AuKill drops a driver named PROCEXP.SYS (from the release version 16.32 of process Explorer) into the C:\Windows\System32\drivers path. The legitimate Process Explorer driver is named PROCEXP152.sys, and normally is found in the same location. Both drivers can be present on a machine that has a copy of Process Explorer running. The AuKill installer also drops an executable copy of itself to either the System32 or the TEMP directory, which it runs as a service as seen below.EventCode: 4697ProcessId: 660ServiceAccount: LocalSystemServiceFileName: C:\Windows\system32\auSophos.exeServiceName: auSophosServiceStartType: 2ServiceType: 0x10SubjectDomainName: SNAPATTACKSubjectLogonId: 0x3e7SubjectUserName: MSEDGEWIN10$SubjectUserSid: S-1-5-18SystemTime: '2023-04-26 15:25:24.920066 UTC'action: successname: A service was installed in the systemproduct: Windowsservice: auSophosservice_name: auSophossigma_product: windowssigma_service: securitystart_mode: autostatus: startedAnother interesting thing that this tool does that we hadn’t seen in many of the open source tools was disabling the Windows Update Service.

A process priority can also be changed after being created by using the SetPriorityClass function or various tools that expose that function, such as Task Manager and Process Explorer (by right-clicking on the process and choosing a new priority class). For example, you can lower the priority of a CPU-intensive process so that it does not interfere with normal system activities. Changing the priority of a process changes the thread priorities up or down, but their relative settings remain the same. It usually doesn’t make sense, however, to change individual thread priorities within a process, because unless you wrote the program or have the source code, you don’t really know what the individual threads are doing, and changing their relative importance might cause the program not to behave in the intended fashion.Normally, the process base priority (and therefore the starting thread base priority) will default to the value at the middle of each process priority range (24, 13, 10, 8, 6, or 4). However, some Windows system processes (such as the Session Manager, service controller, and local security authentication server) have a base process priority slightly higher than the default for the Normal class (8). This higher default value ensures that the threads in these processes will all start at a higher priority than the default value of 8. These system processes use an internal system call (NtSetInformationProcess) to set their process base priority to a numeric value other than the normal default starting base priority.Windows Scheduling APIsThe Windows API functions that relate to thread scheduling are listed in Table 5-15.

Multi-Cannon Gimballed – 22 seconds shields, 40 kill. Damage done by burst and beam lasers evens out if you fire for longer period of time because of beam laser overheat; Against Shields difference is only couple seconds; Fixed weapons work better because the target is huge and you miss less even and fixed weapons are more powerful than gimballed (around 20-25%); Go for focused lasers if you are hunting big targets, they do better against bigger ships, even focused pulse laser was better against asp compared to eagle and sidie. 127 Elite: Dangerous Pilot's Guide Comparing thermal weapons Name Beam Fixed Beam Gimballed Pulse Fixed Burst Fixed Burst Gimballed Pulse Focused Gimballed Pulse Gimballed Pulse Low Heat Fixed Multi-Cannon Gimballed Name Beam Fixed Burst Fixed Pulse Focused Gimballed Pulse Gimballed Pulse Fixed Multi-Cannon Gimballed Beam Gimballed Burst Gimballed Pulse Low Heat Fixed Sidewinder Eagle Asp Explorer Shields Kill all Shield Kill Shots Shield Kill Shield Kill all (s) (s) 2 16 2 6 4 33 8 55 3 12 3 17 6 41 12 70 2 16 26 4 14 6 38 12 68 4 19 18 4 14 5 27 13 60 3 21 35 4 14 6 46 13 81 3 15 44 5 14 6 37 14 66 5 19 42 4 23 6 25 15 67 3 31 39 5 21 7 52 15 104 3 11 - 13 17 22 40 38 68 Sidewinder Eagle Asp Explorer Shields Kill all Shield Kill Shots Shield Kill Shield Kill all (s) (s) 2 16 2 6 4 33 8 55 4 19 18 4 14 5 27 13 60 3 15 44 5 14 6 37 14 66 5 19 42 4 23 6 25
