Admin activity compromised physical surveillance (e.g.: video camera) partially mitigated Legacy (Tails/SVS)

THREAT103 · Partially mitigated: Some controls are in place, but the risk is still too high. · Defined in catalog.py:1792

Risk: High impact × Low likelihood = 6 medium
After mitigations: High impact × Low likelihood = 6 medium (unchanged)

How statuses and scores work

An adversary directly observes admin keystrokes or activity through visual surveillance such as cameras or shouldersurfing

Threat actors: Nation State / Law Enforcement

Mitigations

Mitigation	Status
SSH password auth disabled, requires key MITIG20	implemented
Tor onion creds stored in file, rarely displayed on screen (not really a mitigation... ) MITIG131 Legacy (Tails/SVS)	implemented

Possible further mitigations

2FA access for SecureDrop servers MITIG127 Legacy (Tails/SVS) proposed

Residual risk

Candidate for further mitigation efforts.

Notes

Existing mitigations: SSH authentication is key-based, only the passphrase could be observed (MITIG20). Tor hidden service cookie is in a config file and cannot be easily observed (MITIG131). Further mitigations: Console access requires 2-Factor authentication, which can only be eavesdropped at enroll-time (MITIG127). Automated test for mitigation: No.
