# Very hacky quick check for sha1-hulud for gitlab repos
# Need to set the GITLAB_URL and GITLAB_PAT
# Also use the CSV provided by https://github.com/wiz-sec-public/wiz-research-iocs/blob/main/reports/shai-hulud-2-packages.csv and create a patternfile
# Patternfile creation:
# curl https://raw.githubusercontent.com/wiz-sec-public/wiz-research-iocs/refs/heads/main/reports/shai-hulud-2-packages.csv > sha1-hulud-2-packages.csv
# tail -n +2 sha1-hulud-2-packages.csv | awk -F ',' '{print $1}' > patternfile
# pip install GitPython requests
# You need to have ripgrep installed too
# apt-get install ripgrep
