A security analyst must assess employee login strength with minimal lockouts. The team suspects a few repeated passphrases across user accounts. Which method lets them test those passphrases on a wide range of users without triggering lock exhaustion?
Generate random phrases for each account in rapid succession to find valid credentials.
Cycle through a single passphrase for the user group, then shift to the next passphrase for that group.
Test multiple passphrases on one account in sequence until a valid credential is discovered.
Collect network authentication exchanges and reuse them on other accounts for unauthorized entry.
The correct approach tries each passphrase once across numerous accounts, reducing repeated failure on any single profile. This rotation helps avoid automatic lock measures while identifying shared passcodes. Generating random passphrases for each user is more akin to brute force and is not centered on known passphrases. Testing multiple passphrases in a row on one profile risks immediate lock events. Reusing intercepted credential data focuses on replaying valid information rather than performing distributed attempts across many different accounts.
