Cobalt Strike Beacon Config Extractor
Extract Cobalt Strike beacon configuration from memory dumps and PE payloads. CyberNexus Decoder locates the config block, tries common XOR keys (0x69, 0x2E, 0x00), and parses settings: C2 server, port, user agent, sleep time, spawn targets, and watermark.
Open the cobalt strike config extractor tool →How to use the cobalt strike config extractor
- Upload the beacon payload, memory dump, or extracted config blob.
- Run "Parse Cobalt Strike Config" to locate and decode the settings.
- Review extracted C2 servers, ports, user agents, and sleep configuration.
- If the config is custom-encrypted, recover the key with "XOR Key Recovery" first.
Features
- Automatic config block location with common XOR keys.
- Parses C2 server, port, user agent, sleep, jitter, spawn-to, and watermark.
- String-scan fallback for C2 indicators when the config is non-standard.
- Pairs with XOR Key Recovery for encrypted beacons.
Frequently asked questions
How do I extract a Cobalt Strike beacon config?
Load the beacon payload and run Parse Cobalt Strike Config. It locates the configuration block and decodes the malleable C2 settings.
What if the beacon uses a custom XOR key?
Run XOR Key Recovery to find the key, apply XOR, then run the config parser again on the decrypted output.
