Tips and Tricks

Here are a few tricks that I have discovered over my malware development journey:

  • Encrypt and change permissions of your payload and modules if there are not in use.
  • EDRs scans RWX memory pages, try to RW PAGE_READWRITE -> RX PAGE_EXECUTE_READ.
  • Use the APIs closest to kernel, produce less telemetry.
  • Obfuscate all the calls.
  • Duplicate handles instead of create new ones.
  • Inject from noisy contexts like SYSTEM or csrss.exe.
  • The idea of evasion consists of being invisible by being common.
