Last Week in Security is a summary of the interesting cybersecurity news, techniques, tools and exploits from the previous week. This post covers 2021-08-16 to 2021-08-23.



Tools and Exploits

  • Added EfsRpc method (aka PetitPotam). SweetPotato gets a PetitPotam upgrade so if you have SeImpersonatePrivilege on a fully patched windows 10 machine, you can get SYSTEM.
  • ServiceMove-BOF is a new lateral movement technique by abusing Windows Perception Simulation Service to achieve DLL hijacking code execution. Note that is work on Windows 10 1809 or above only.
  • BOF-ForeignLsass dumps lsass memory by opening a handle to a process that already has a handle open to lsass, with the hopes of looking less suspicious by stealing this "legitimate" handle.
  • kubescape is the first tool for testing if Kubernetes is deployed securely as defined in Kubernetes Hardening Guidance by to NSA and CISA.
