What surprised me is they put backdoor access to their own consumer server.

Step-by-Step Guide: From .deb Extraction to Full Script Recovery
This document reproduces the exact workflow used to extract and analyze the embedded bash installer script from the cephas_1.0_amd64.deb package by tracing runtime behavior and decoding the installer payload captured in execve arguments.
The flow starts at extracting the .deb, proceeds through OS spoofing and strace capture, and ends with script extraction using extract_script.py (re-created here).
OS: Linux (root)
Package: cephas_1.0_amd64.deb
cephas_1.0_amd64.deb
extracted_cephas/ (created by dpkg-deb)
extract_script.py (this repo – script to pull the embedded installer from an strace log)
cephas_installer_script.sh (final recovered installer script)
trace.log (strace capture)
Install the minimal tooling (root):
apt-get update
apt-get install -y \
strace \
python3 \
file
Optional (useful for extra analysis, not strictly required for extraction):
apt-get install -y binwalk xxd ltrace tree
Follow the official installation guide: https://github.com/PRIV8TOOL/CEPHAS
If the package is still available in the repository, you can download it directly:
apt download cephas
If it has been removed upstream, use the bundled artifact included with this archive:
cephas_1.0_amd64.deb
# From the workspace root
cd /root/CookSC
# Extract package contents
mkdir -p extracted_cephas
dpkg-deb -x cephas_1.0_amd64.deb extracted_cephas
# Inspect the main binary
file extracted_cephas/usr/local/bin/cephas
Expected: an x86-64 PIE ELF, dynamically linked (self-extracting behavior observed at runtime).
The installer exits early unless it detects Ubuntu 22.04/24.04. Spoof the OS version temporarily to allow the binary to reach its embedded script runner.
# Backup original file (important!)
cp /etc/os-release /etc/os-release.backup
# Minimal spoof to mimic Ubuntu 22.04
echo 'VERSION_ID="22.04"' > /tmp/fake-os
cp /tmp/fake-os /etc/os-release
Use strace with full-string capture so the script text passed via -c "..." is not truncated.
# Trace execution with full argument capture
strace -f -s 100000 -e execve cephas 2>&1 > trace.log
Notes:
-f follows forks.
-s 100000 prevents long argument truncation.
-e execve restricts logging to process execs (clearer logs, smaller file).
This repository includes extract_script.py which robustly unescapes the script captured by strace (handles \n, octal/hex escapes, quotes). If you don't see it, re-create it as below or confirm it exists at ./extract_script.py.
Usage:
# Option A: write to stdout
python3 extract_script.py trace.log > cephas_installer_script.sh
# Option B: write to file directly
python3 extract_script.py trace.log -o cephas_installer_script.sh
The resulting cephas_installer_script.sh should be ~1.7K lines and contain the complete interactive installer logic (colors, OS checks, LAMP setup, vhost + SSL, Telegram reporting, remote ZIP download/extract, etc.).
Always restore your real /etc/os-release once finished:
cp /etc/os-release.backup /etc/os-release
wc -l cephas_installer_script.sh
head -n 20 cephas_installer_script.sh
You should see a shebang and the structured installer content (functions, menus, logging).
A copy is provided in this repo at ./extract_script.py. It:
Searches execve() entries for shells (bash, sh, dash).
Locates the -c "<script>" payload argument.
Robustly unescapes strace-encoded strings (prevents UnicodeDecodeError).
Example invocation (as used above):
python3 extract_script.py trace.log > cephas_installer_script.sh
Run all steps in an isolated/sandboxed environment.
Do NOT deploy the recovered payload to production.
The installer contacts external services, writes system config, and reports to Telegram; do not run in sensitive environments.
# 0) Prereqs
apt-get update && apt-get install -y strace python3 file
# 1) Extract package
cd /root/CookSC
mkdir -p extracted_cephas
dpkg-deb -x cephas_1.0_amd64.deb extracted_cephas
# 2) OS spoof (backup first!)
cp /etc/os-release /etc/os-release.backup
echo 'VERSION_ID="22.04"' > /tmp/fake-os && cp /tmp/fake-os /etc/os-release
# 3) Trace
strace -f -s 100000 -e execve cephas 2>&1 > trace.log
# 4) Extract script (requires extract_script.py in this directory)
python3 extract_script.py trace.log > cephas_installer_script.sh
# 5) Restore OS file
cp /etc/os-release.backup /etc/os-release
