GSIL(GitHub Sensitive Information Leakage)

Monitor Github sensitive information leaks in near real time and send alert notifications.

Installation

Python3(Python2 is not tested)

$ git clone https://github.com/FeeiCN/GSIL.git
$ cd GSIL/
$ pip install -r requirements.txt

Configuration

GSIL/config.gsil(Copy config.gsil.cfg.example to config.gsil.cfg): Alarm mailbox and Github configuration

[mail]
host : smtp.exmail.qq.com
# SMTP port (Not SSL port, but will use TLS encryption)
port : 25
# Multiple senders are separated by comma (,)
mails : gsil@domain.com
from : GSIL
password : your_password
# Multiple recipients are separated by comma (,)
to : feei@feei.cn

[github]
# Whether the scanned data will be cloned to the local area immediately
# Clone to ~/.gsil/codes/ directory
clone: false

# Github Token, multiple tokens are separated by comma (,)
# https://github.com/settings/tokens
tokens : your_token

GSIL/rules.gsil(Copy rules.gsil.yaml.example to rules.gsil.yaml): scanning rules

Generally, The best rule is the characteristic code of the intranet(Example: mogujie's extranet is mogujie.com, intranet is mogujie.org. At this time, mogujie.org can be used as a rule)

There are other similar code head characteristic code, external mailbox characteristic code, and so on

field	meaning	optional	default	describe
keyword	key word	required	-	When multiple keywords are used, space segmentation is used(Example: `'username password'`), When you need a precise search, use double(Example: `"quotesele.me"`)
ext	file suffix	optional	all suffixes	Multiple suffixes are separated by comma(Example: `java,php,python`)
mode	matching mode	optional	normal-match	`normal-match`(The line that contains the keyword is matched, and the line near the line is matched) / `only-match`(Only the lines that match the key words) / `full-match`(Not recommended for use)(The search results show the entire file)

{
    # usually using the company name, used as the first parameter to open the scan(Example:`python gsil.py test`)
    "test": {
        # General use of product name
        "mogujie": {
            # Internal domain name of the company
            "\"mogujie.org\"": {
                # mode/ext options no need to configure by default
                "mode": "normal-match",
                "ext": "php,java,python,go,js,properties"
            },
            # Company code's characteristic code
            "copyright meili inc": {},
            # Internal host domain name
            "yewu1.db.mogujie.host": {},
            # External mailbox
            "mail.mogujie.com": {}
        },
        "meilishuo": {
            "meilishuo.org": {},
            "meilishuo.io": {}
        }
    }
}

Usage

$ python gsil.py test

# Verify tokens validity
$ python gsil.py --verify-tokens

$ crontab -e

# Run every hour
0 * * * * /usr/bin/python /var/app/GSIL/gsil.py test > /tmp/gsil
# Send a statistical report at 11 p. m. every night
0 23 * * * /usr/bin/python /var/app/GSIL/gsil.py --report

Once the scan report will not repeat the report, the cache records in ~/.gsil/ directory *
