Source/destination hash mismatch undermines forensic reliability. It could help resolve forensic disk hash mismatch, but it would not govern external sharing of volatile evidence.

Evidence collection must preserve availability and chain of custody. It would acquire disk evidence from critical server safely, but it would not govern external sharing of volatile evidence.

Shutdown can lose memory-only evidence and complicate encrypted storage access. It could help preserve live evidence before laptop shutdown, but it would not govern external sharing of volatile evidence.

Signature validity does not guarantee a build pipeline was uncompromised. That is relevant to supply-chain malware incident, not to contain malicious supplier update rollout.

Preventing pending installations limits future spread. It would stop pending compromised supplier software install, but it would not contain malicious supplier update rollout.

Supply-chain incidents can recur if the distribution authority stays compromised. That is relevant to supply-chain malware incident, not to contain malicious supplier update rollout.

Recurring task execution can maintain attacker access. It would remove unauthorized scheduled-task persistence, but it would not avoid misattribution by common task name.

Legitimate scheduled tasks can shift when configuration or time sources change. It could help distinguish changed admin schedule from attacker persistence, but it would not avoid misattribution by common task name.

Removing one foothold does not guarantee eradication of others. That is relevant to malicious scheduled task persistence, not to avoid misattribution by common task name.

Inconsistent time bases can reverse apparent attack order. That is relevant to timeline and scope reconstruction, not to resolve incident initial access uncertainty.

Scope estimates should reflect confirmed stages rather than one aggregated count. It would classify attempted versus executed lateral access, but it would not resolve incident initial access uncertainty.

Missing data should be explicitly bounded instead of filled with assumptions. It could help handle forensic timeline visibility gap, but it would not resolve incident initial access uncertainty.

Application consent can preserve attacker reach beyond user password remediation. That is relevant to privileged identity takeover, not to contain confirmed privileged session compromise.

Incident scope should not attribute all prior activity to the intruder. It could help bound privileged account compromise timeline, but it would not contain confirmed privileged session compromise.

Password rotation does not necessarily terminate already-issued access tokens. That is relevant to privileged identity takeover, not to contain confirmed privileged session compromise.

Network containment limits autonomous worm spread. It would contain self-propagating SMB malware, but it would not avoid indiscriminate file-share shutdown.

Stale last-seen evidence cannot prove malware absence. It could help validate unobserved endpoint after worm event, but it would not avoid indiscriminate file-share shutdown.

Eradication requires closing the exploit route that enabled propagation. It would close SMB worm propagation vulnerability, but it would not avoid indiscriminate file-share shutdown.

Web process shell execution indicates likely server compromise. It could help contain suspected active web shell, but it would not investigate residual web-shell persistence.

Web-server footholds can be used as pivots to other infrastructure. That is relevant to web shell on application server, not to investigate residual web-shell persistence.

Fixing the entry vulnerability does not automatically eradicate attacker code. It would eradicate post-exploit web-shell persistence, but it would not investigate residual web-shell persistence.

Broad unrelated collection undermines proportionate incident handling. It would limit insider investigation evidence scope, but it would not eradicate insider retained cloud access.

Legitimate data access can resemble exfiltration without policy context. It could help distinguish authorized bulk data movement, but it would not eradicate insider retained cloud access.

Insider investigation requires provenance and privacy-aware governance. That is relevant to insider data theft investigation, not to eradicate insider retained cloud access.

Network containment alone does not eliminate stolen application credentials. It would eradicate credential source of exfiltration, but it would not distinguish blocked transfer attempt from success.

Active suspicious bulk transfer needs prompt containment and scope collection. That is relevant to network exfiltration response, not to distinguish blocked transfer attempt from success.

Encryption does not make an unauthorized transfer harmless. It would evaluate encrypted exfiltration artifact, but it would not distinguish blocked transfer attempt from success.

Root access invalidates trust in local binaries and audit data. It could help contain confirmed root escalation, but it would not eradicate residual root SSH trust.

Authorization configuration tampering can create persistent elevated privilege. That is relevant to privilege escalation and root access, not to eradicate residual root SSH trust.

Denied elevation attempts are not proof of elevated execution. It could help distinguish failed sudo attempt from root takeover, but it would not eradicate residual root SSH trust.

Active suspicious bulk transfer needs prompt containment and scope collection. That is relevant to network exfiltration response, not to evaluate encrypted exfiltration artifact.

Denial telemetry cannot establish successful exfiltration. It would distinguish blocked transfer attempt from success, but it would not evaluate encrypted exfiltration artifact.

Network containment alone does not eliminate stolen application credentials. It could help eradicate credential source of exfiltration, but it would not evaluate encrypted exfiltration artifact.
