Episode 57: Password Attack Indicators (Domain 2)

Password attacks are among the most common initial access vectors, and recognizing their early indicators is key to stopping intrusions before they escalate. In this episode, we focus on signs of brute-force attempts, credential stuffing, and password spraying—where attackers test a small set of passwords across many accounts to avoid lockouts. Indicators include repeated failed login attempts, unusual login times or geographies, multiple accounts locking out simultaneously, and automated patterns in authentication logs. We also explore the role of multi-factor authentication (MFA) in resisting these attacks, while noting that MFA fatigue and token hijacking can still occur. Monitoring tools like SIEMs, login velocity tracking, and alert correlation can help detect password-based attacks in real time. A single failed login may be harmless—but patterns reveal intent. Recognizing these early warning signs gives defenders the chance to intervene before access is gained or lateral movement begins.
