Zana za Lugha Mbalimbali

Naxus - AI-Gents

Kuna kifurushi cha bure cha kukagua PRs.

Semgrep

Ni zana ya Chanzo Huria.

Lugha Zinazoungwa Mkono

Anza Haraka

# Install https://github.com/returntocorp/semgrep#option-1-getting-started-from-the-cli
brew install semgrep

# Go to your repo code and scan
cd repo
semgrep scan --config auto

Unaweza pia kutumia la semgrep VSCode Extension kupata matokeo ndani ya VSCode.

SonarQube

Kuna toleo la bure linaloweza kusakinishwa.

Kuanzia Haraka

# Run the paltform in docker
docker run -d --name sonarqube -e SONAR_ES_BOOTSTRAP_CHECKS_DISABLE=true -p 9000:9000 sonarqube:latest
# Install cli tool
brew install sonar-scanner

# Go to localhost:9000 and login with admin:admin or admin:sonar
# Generate a local project and then a TOKEN for it

# Using the token and from the folder with the repo, scan it
cd path/to/repo
sonar-scanner \
-Dsonar.projectKey=<project-name> \
-Dsonar.sources=. \
-Dsonar.host.url=http://localhost:9000 \
-Dsonar.token=<sonar_project_token>

CodeQL

Kuna toleo la bure linaloweza kusakinishwa lakini kulingana na leseni unaweza kutumia toleo la bure la codeQL tu katika miradi ya Open Source.

Install

# Download your release from https://github.com/github/codeql-action/releases
## Example
wget https://github.com/github/codeql-action/releases/download/codeql-bundle-v2.14.3/codeql-bundle-osx64.tar.gz

# Move it to the destination folder
mkdir ~/codeql
mv codeql-bundle* ~/codeql

# Decompress it
cd ~/codeql
tar -xzvf codeql-bundle-*.tar.gz
rm codeql-bundle-*.tar.gz

# Add to path
echo 'export PATH="$PATH:/Users/username/codeql/codeql"' >> ~/.zshrc

# Check it's correctly installed
## Open a new terminal
codeql resolve qlpacks #Get paths to QL packs

Quick Start - Andaa hifadhidata

• Unaweza kuruhusu codeql kutambua kiotomatiki lugha ya repo na kuunda hifadhidata

codeql database create <database> --language <language>

# Example
codeql database create /path/repo/codeql_db --source-root /path/repo
## DB will be created in /path/repo/codeql_db

• Unaweza kufanya hivi kwa mikono ukionyesha repo na lugha (orodha ya lugha)

codeql database create <database> --language <language> --source-root </path/to/repo>

# Example
codeql database create /path/repo/codeql_db --language javascript --source-root /path/repo
## DB will be created in /path/repo/codeql_db

• Ikiwa repo yako inatumia zaidi ya lugha 1, unaweza pia kuunda DB 1 kwa kila lugha ukionyesha kila lugha.

export GITHUB_TOKEN=ghp_32849y23hij4...
codeql database create <database> --source-root /path/to/repo --db-cluster --language "javascript,python"

# Example
export GITHUB_TOKEN=ghp_32849y23hij4...
codeql database create /path/repo/codeql_db --source-root /path/to/repo --db-cluster --language "javascript,python"
## DBs will be created in /path/repo/codeql_db/*

• Unaweza pia kuruhusu codeql kutambua lugha zote kwa ajili yako na kuunda DB kwa kila lugha. Unahitaji kumpa GITHUB_TOKEN.

export GITHUB_TOKEN=ghp_32849y23hij4...
codeql database create <database> --db-cluster --source-root </path/to/repo>

# Example
export GITHUB_TOKEN=ghp_32849y23hij4...
codeql database create /tmp/codeql_db --db-cluster --source-root /path/repo
## DBs will be created in /path/repo/codeql_db/*

Quick Start - Analyze the code

Kumbuka kwamba ikiwa ulitumia lugha kadhaa, DB kwa kila lugha ingekuwa imeundwa katika njia uliyotaja.

# Default analysis
codeql database analyze <database> --format=<format> --output=</out/file/path>
# Example
codeql database analyze /tmp/codeql_db/javascript --format=sarif-latest --output=/tmp/graphql_results.sarif

# Specify QL pack to use in the analysis
codeql database analyze <database> \
<qls pack> --sarif-category=<language> \
--sarif-add-baseline-file-info \ --format=<format> \
--output=/out/file/path>
# Example
codeql database analyze /tmp/codeql_db \
javascript-security-extended --sarif-category=javascript \
--sarif-add-baseline-file-info --format=sarif-latest \
--output=/tmp/sec-extended.sarif

Quick Start - Scripted

export GITHUB_TOKEN=ghp_32849y23hij4...
export REPO_PATH=/path/to/repo
export OUTPUT_DIR_PATH="$REPO_PATH/codeql_results"
mkdir -p "$OUTPUT_DIR_PATH"
export FINAL_MSG="Results available in: "

echo "Creating DB"
codeql database create "$REPO_PATH/codeql_db" --db-cluster --source-root "$REPO_PATH"
for db in `ls "$REPO_PATH/codeql_db"`; do
echo "Analyzing $db"
codeql database analyze "$REPO_PATH/codeql_db/$db" --format=sarif-latest --output="${OUTPUT_DIR_PATH}/$db).sarif"
FINAL_MSG="$FINAL_MSG ${OUTPUT_DIR_PATH}/$db.sarif ,"
echo ""
done

echo $FINAL_MSG

Unaweza kuona matokeo katika https://microsoft.github.io/sarif-web-component/ au kutumia nyongeza ya VSCode SARIF viewer.

Unaweza pia kutumia nyongeza ya VSCode kupata matokeo ndani ya VSCode. Bado utahitaji kuunda database kwa mikono, lakini kisha unaweza kuchagua faili zozote na kubonyeza Right Click -> CodeQL: Run Queries in Selected Files

Snyk

Kuna toleo la bure linaloweza kusakinishwa.

Quick Start

# Install
sudo npm install -g snyk

# Authenticate (you can use a free account)
snyk auth

# Test for open source vulns & license issues
snyk test [--all-projects]

# Test for code vulnerabilities
## This will upload your code and you need to enable this option in: Settings > Snyk Code
snyk test code

# Test for vulns in images
snyk container test [image]

# Test for IaC vulns
snyk iac test

Unaweza pia kutumia snyk VSCode Extension kupata matokeo ndani ya VSCode.

Insider

Ni Open Source, lakini inaonekana haijatunzwa.

Lugha Zinazoungwa Mkono

Java (Maven na Android), Kotlin (Android), Swift (iOS), .NET Full Framework, C#, na Javascript (Node.js).

Static Analysis

Unminimize/Beautify/Prettify

• https://prettier.io/playground/
• https://beautifier.io/
• Tazama baadhi ya zana zilizotajwa katika 'Deobfuscate/Unpack' hapa chini pia.

Deobfuscate/Unpack

Note: Inaweza kuwa haiwezekani kuondoa kabisa obfuscation.

1. Tafuta na tumia .map files:

• Ikiwa .map files zimefunuliwa, zinaweza kutumika kwa urahisi kuondoa obfuscation.
• Kwa kawaida, foo.js.map inahusiana na foo.js. Tafuta kwa mikono.
• Tumia JS Miner kutafuta.
• Hakikisha skana hai inafanywa.
• Soma 'Tips/Notes'
• Ikiwa zimepatikana, tumia Maximize kuondoa obfuscation.

2. Bila .map files, jaribu JSnice:

• Marejeleo: http://jsnice.org/ & https://www.npmjs.com/package/jsnice
• Vidokezo:
• Ikiwa unatumia jsnice.org, bonyeza kitufe cha chaguzi kilicho karibu na kitufe cha "Nicify JavaScript", na uondoe "Infer types" ili kupunguza machafuko katika msimbo.
• Hakikisha huachi mistari yoyote tupu kabla ya script, kwani inaweza kuathiri mchakato wa kuondoa obfuscation na kutoa matokeo yasiyo sahihi.

3. Kwa baadhi ya mbadala za kisasa zaidi za JSNice, unaweza kutaka kuangalia yafuatayo:

• https://github.com/pionxzh/wakaru

• Javascript decompiler, unpacker na unminify toolkit Wakaru ni decompiler ya Javascript kwa frontend ya kisasa. Inarejesha msimbo wa asili kutoka kwa chanzo kilichofungwa na kilichotafsiriwa.

• https://github.com/j4k0xb/webcrack

• Deobfuscate obfuscator.io, unminify na unpack javascript iliyofungwa

• https://github.com/jehna/humanify

• Un-minify Javascript code using ChatGPT Zana hii inatumia mifano mikubwa ya lugha (kama ChatGPT & llama2) na zana nyingine kuondoa un-minify Javascript code. Kumbuka kwamba LLMs hazifanyi mabadiliko yoyote ya muundo – zinatoa tu vidokezo vya kubadilisha majina ya mabadiliko na kazi. Kazi nzito inafanywa na Babel kwenye kiwango cha AST ili kuhakikisha msimbo unabaki sawa.

• https://thejunkland.com/blog/using-llms-to-reverse-javascript-minification.html

• Kutumia LLMs kubadilisha majina ya mabadiliko ya Javascript

3. Tumia console.log();

• Tafuta thamani ya kurudi mwishoni na ibadilishe kuwa console.log(<packerReturnVariable>); ili js iliyondolewa obfuscation iweze kuchapishwa badala ya kutekelezwa.
• Kisha, bandika js iliyobadilishwa (na bado imefichwa) kwenye https://jsconsole.com/ ili kuona js iliyondolewa obfuscation ikichapishwa kwenye console.
• Mwishowe, bandika matokeo yaliyondolewa obfuscation kwenye https://prettier.io/playground/ ili kuipamba kwa uchambuzi.
• Note: Ikiwa bado unaona js iliyofungwa (lakini tofauti), inaweza kuwa imefungwa kwa kurudi. Rudia mchakato.
