How to identify and crack a MongoDB SCRAM-SHA-1 hash

MongoDB SCRAM-SHA-1 is a database hash type. It is fast and typically unsalted, which makes weak passwords recoverable quickly on consumer GPU hardware. This page shows how to recognise it and the exact commands to attack it.

All identification runs locally in WebAssembly. The commands below write the hash to a local file on your machine — nothing is sent to this site.

Identifying the hash

The hash identifier on the home page detects MongoDB SCRAM-SHA-1 entirely in your browser — your hash is never uploaded. A typical example looks like this:

$mongodb-scram$*0*dXNlcg==*10000*c2FsdA==*...

Cracking MongoDB SCRAM-SHA-1 with hashcat

Save the hash to a file and run hashcat in mode -m 24100. Start with a wordlist such as rockyou.txt:

echo '$mongodb-scram$*0*dXNlcg==*10000*c2FsdA==*...' > hash.txt && hashcat -m 24100 hash.txt /usr/share/wordlists/rockyou.txt

Add a rule set to mutate dictionary words (capitalisation, leetspeak, appended digits) and dramatically widen coverage:

echo '$mongodb-scram$*0*dXNlcg==*10000*c2FsdA==*...' > hash.txt && hashcat -m 24100 hash.txt /usr/share/wordlists/rockyou.txt -r /usr/share/hashcat/rules/best64.rule
