CyberNexus Decoder — Online Malware Deobfuscator & Decoder
A free, private, browser-based cyber security toolbox and modern CyberChef alternative. Decode and deobfuscate malware payloads — Base64, Hex, XOR, PowerShell, JavaScript, VBA macros and more — entirely client-side. No data is ever uploaded to a server.
What you can do with CyberNexus Decoder
- Decode encodings: Base64, Base32, Base58, Base62, Base85, Hex, Binary, URL, and Morse.
- Deobfuscate scripts: PowerShell (EncodedCommand, format strings, backticks), obfuscated JavaScript, VBA macros, and CMD/batch.
- Decrypt & recover keys: AES, DES, Triple DES, RC4, XOR with automatic key recovery, and Shikata Ga Nai shellcode.
- Analyze binaries: PE header parsing, packer detection (UPX, Themida, VMProtect), OLE/VBA stream extraction, and entropy mapping.
- Hash & verify: MD5, SHA-1, SHA-256, SHA-384, SHA-512, SHA-3, RIPEMD-160, HMAC, and PBKDF2.
- Extract IOCs: IPs, URLs, domains, file hashes, crypto wallets, registry keys, and mutexes for threat intelligence.
- Auto-detect: The Magic auto-detector identifies encoding layers and suggests a decode recipe automatically.
Built for security analysts and DFIR teams
CyberNexus Decoder is designed for SOC analysts, threat hunters, malware researchers, and incident responders who need to triage suspicious payloads quickly and safely. Because everything runs locally in your browser, sensitive samples and indicators of compromise never leave your machine.
