Google Drive Links Never Expire — Security Risk
The article explains that Google Drive links shared using the "anyone with the link can view" setting do not expire by default, leaving files accessible indefinitely unless manually revoked. This creates a common security and compliance exposure for organizations, agencies, contractors and former employees who may retain access via old links. Citing industry research, the author notes the average company has thousands of externally shared Workspace files and that very few organizations audit or revoke such access routinely. The piece urges improvements — automatic link expiration, centralized access auditing and offboarding integration — and recommends immediate mitigations (quarterly audits, avoid public links, add revoke steps to offboarding). It also highlights regulatory risk (GDPR, SOC 2) when sensitive or regulated data remains accessible via stale links.
Persistent, non-expiring shared links increase security and compliance risk for agencies, marketing teams and organizations that use Google Workspace to share assets — a manageable but material operational issue for many teams.

Key Takeaways & Evidence Grounding
- Google Drive links shared with "anyone with the link can view" do not expire by default.
- A Metomic study (as cited) found the average company has over 10,000 files shared externally through Google Workspace.
- The article claims only about 5% of companies have any process for auditing or revoking external sharing (per the Metomic citation).
- The piece cites Varonis's Global Data Risk Report stating the average employee has access to 17 million files on day one (as reported).
- Google Workspace offers some advanced sharing/audit features for Enterprise customers, but smaller plans lack built-in defaults and many admins do not configure protections.

Secure Client Link Sharing: Custom URLs, Passwords, Expirations
This developer guide explains simple, practical controls to make client link sharing safer: use readable custom URLs, add password protection for private shares, and set expiration dates so temporary links end automatically. The article outlines why random or permanent links create risk, proposes a short checklist and a seven-step workflow (create for purpose, readable URL, optional password, set expiration, send context, share password separately, revoke/extend), and gives recommended expiration rules for demos, reviews and temporary files. The author notes GhostlyShare (from GhostlyInc) as a tool built to implement this workflow. Published 2026-05-31.
Deleted Google API Keys Remain Active for 23 Minutes
A security researcher (Joe Leon) found that deleting a Google API key does not immediately invalidate it: due to eventual consistency and cached credential state across Google Cloud's distributed authentication layer, revoked keys can remain valid for up to 23 minutes. Google initially called this expected behavior but later reclassified the issue as a critical P0/S0 bug after public disclosure. The problem is amplified because Google reused the same API key infrastructure for Gemini (LLM) as for lower-risk services like Maps, increasing the blast radius of leaked keys. The article explains implications for incident response, compares propagation/invalidations for AWS and Postmark, and recommends stricter key restrictions, backend proxies for sensitive APIs, credential rotation, explicit session invalidation, billing alerts, and enhanced monitoring after key deletion.
Avoid Storing Full Magic Links in Audit Logs
The article warns that passwordless 'magic link' authentication tokens must be treated like credentials to avoid accidental leakage through logs, traces, support dashboards, and test artifacts. It recommends redacting full verification URLs and raw tokens from observability and support systems while preserving useful audit metadata (attempt id, subject id, channel, redacted destination hint, timestamps, provider message id, and result). The author suggests pairing redacted audit events with idempotent verification handling, implementing a single auth-event formatter, blocking sensitive fields from structured logs, adding tests to detect leaks, and reviewing downstream sinks such as tracing and alert systems.
