Scavenger : Crawler (Bot) Searching For Credential Leaks On Different Paste Sites

Scavenger crawler (Bot) searching for credential leaks on different paste sites. Just the code of my OSINT bot searching for sensitive data leaks on different paste sites.

Search terms:

  • credentials
  • private RSA keys
  • WordPress configuration files
  • MySQL connect strings
  • onion links
  • links to files hosted inside the onion network (PDF, DOC, DOCX, XLS, XLSX)

Keep in mind:

  • This bot is not beautiful. I wrote it quick and dirty and do not care about code conventions or other shit… I will never care about those things.
  • The code is not complete so far. Some parts like integrating the credentials in a database are missing in this online repository.
  • If you want to use this code, feel free to do so. Keep in mind you have to customize things to make it run on your system.
  • I know that I have some false positives and I know that I miss some credentials. So if you think this is crap…ok. leave now. If you have ideas for a better detection, just let me know!
  • And again: QUICK AND DIRTY! Do not expect nice code.

IMPORTANT

The bot can be run in two major modes:

  • API mode
  • Scraping mode (using TOR)

I highly recommend to use the API mode. It is the intended method of scraping pastes from Pastebin.com and it is just fair to do so. The only thing you need is a Pastebin.com PRO account and whitelist your public IP on their site.

To start the bot in API mode just run the program in the following way:

python run.py -0

However, it is not always possible to use this intended method, as you might be in NAT mode and therefore you do not have an IP exclusively (whitelisting your IP is not reasonable here). That is the reason I also implemented a scraping mode where fast TOR cycles in combination with reasonable user agents are used to avoid IP blocking and Cloudflare captchas.

To start the bot in scraping mode run it in the following way:

python run.py -1

Important note: you need the TOR service installed on your system listening on port 9050. Additionally you need to add the following line to your /etc/tor/torrc file.

MaxCircuitDirtiness 30

This sets the maximum cycle time of TOR to 30 seconds.

Usage

To learn how to use the software you just need to call the run.py script with the -h/–help argument.

python run.py -h

Output:

usage: run.py [-h] [-0] [-1] [-2] [-ps]

Control software for the different modules of this paste crawler.

optional arguments:
-h, –help show this help message and exit
-0, –pastebinCOMapi Activate Pastebin.com module (using API)
-1, –pastebinCOMtor Activate Pastebin.com module (standard scraping using
TOR to avoid IP blocking)
-2, –pasteORG Activate Paste.org module
-ps, –pStatistic Show a simple statistic.

So far I only implemented the Pastebin.com module and I am working on Paste.org. I will add more modules and update this script over time.

Just start the Pastebin.com module separately (first module I implemented)…

python P_bot.py

Pastes are stored in data/raw_pastes until they are more then 48000. When they are more then 48000 they get filtered, ziped and moved to the archive folder. All pastes which contain credentials are stored in data/files_with_passwords

Keep in mind that at the moment only combinations like USERNAME:PASSWORD and other simple combinations are detected. However, there is a tool to search for proxy logs containing credentials.

You can search for proxy logs (URLs with username and password combinations) by using getProxyLogs.py file

python getProxyLogs.py data/raw_pastes

If you want to search the raw data for specific strings you can do it using searchRaw.py (really slow).

python searchRaw.py SEARCHSTRING

To see statistics of the bot just call

python status.py

The file findSensitiveData.py searches a folder (with pastes) for sensitive data like credit cards, RSA keys or mysqli_connect strings. Keep in mind that this script uses grep and therefore is really slow on a big amount of paste files. If you want to analyze a big amount of pastes I recommend an ELK-Stack.

python findSensitiveData.py data/raw_pastes

There are two scripts stalk_user.py/stalk_user_wrapper.py which can be used to monitor a specific twitter user. This means every tweet he posts gets saved and every containing URL gets downloaded. To start the stalker just execute the wrapper.

python stalk_user_wrapper.py

To Do

I discovered other sites like Pastebin which allow to read the latest paste and crawl them. I need to integreate them into my bot. If you know additional sites which are worth a look, just let me know.
