Privacy for your command line options

A Linux tool to hide from `ps`

Download (static and upx obfuscated binary):

curl -fL -o zapper https://da.gd/thczap/zapper-linux-x86_64 && \
chmod 755 zapper && \
./zapper -h

Example: Show only 'nmap', but without the command options:

./zapper nmap -sCV -F -Pn scanme.nmap.org
              ^^^^^^^^^^^^^^^^^^^^ will not show

Example: Hide the current shell and all sub processes as some kernel worker:

exec ./zapper -f -a[kworker/1:0-rcu_gp] bash -il

---

1. Does not require root
2. Works also on static binaries (e.g. GoLang)
3. Zaps the environment (/proc/<PID>/environ) as well
4. Does not rely on LD_PRELOAD=
5. Only 00.1% overhead.
6. Stops root from sniffing your processes (-f) (with strace).

Compile:

git clone https://github.com/hackerschoice/zapper.git
cd zapper
make
