Deleted Doesn’t Always Mean Gone

Delete an exposed API key, and access immediately stops. Simple, right? Not exactly.

New research highlighted by Dark Reading found that deleted Google Cloud API keys can reportedly continue authenticating successfully for up to 23 minutes after deletion. That’s a pretty significant window when you’re dealing with incident response, leaked credentials, or active abuse.

According to the testing, the median revocation window was around 16 minutes, and researchers found the behavior varied depending on region and infrastructure routing. For most people outside of IT or security, that may sound minor.

For security teams, it changes the assumption around what “revoked” or “deleted” actually means during an incident.

The Bigger Issue Is Visibility

What stood out wasn’t even the timing itself. It was the operational challenge it creates.

During incident response, teams are often moving quickly:

• disable accounts
• revoke access
• rotate credentials
• contain systems
• verify exposure
• document activity

The expectation is usually that once something is deleted, the risk tied to it is gone immediately. This research is a reminder that modern cloud infrastructure doesn’t always work that way behind the scenes.

In highly distributed systems, changes may take time to fully propagate across environments. That delay may only be minutes, but in cybersecurity, minutes matter. Especially if attackers already have active access.

Security Assumptions Can Create Risk

One thing cybersecurity teams constantly battle is the gap between what people think is happening and what systems are actually doing. A lot of breaches happen in those gaps.

Not because organizations are careless, but because environments have become incredibly complex:

• cloud services
• APIs
• third-party integrations
• automation tools
• service accounts
• temporary credentials
• AI platforms
• distributed infrastructure

All of it creates layers of access and dependencies that are difficult to fully track in real time. That’s why identity, access management, credential governance, and lifecycle visibility have become such major security priorities over the last several years.

Why This Matters Beyond Cloud Security

Stories like this are also a good reminder that security isn’t just about preventing breaches anymore.

It’s about understanding where access exists, how long it exists, and whether organizations can confidently verify when something is truly disabled, destroyed, or removed. That same challenge exists throughout the technology lifecycle.

We see similar conversations happen around:

• retired devices
• old hard drives
• backup media
• decommissioned servers
• employee offboarding
• legacy systems
• downstream IT asset handling

Organizations often assume equipment is “gone,” “offline,” or “disposed of” long before the actual risk is fully eliminated.

In reality, security and compliance exposure can continue well beyond active use if processes, tracking, and chain of custody aren’t fully managed through final disposition.

The Operational Side of Cybersecurity Still Matters

Cybersecurity today isn’t just about blocking attacks. It’s increasingly about operational discipline— understanding how systems behave, validating assumptions, maintaining visibility into your environment, documenting actions, verifying outcomes, and managing access throughout its entire lifecycle.

Technical controls are critical, but even the best security tools can fall short without the processes and oversight needed to support them. In many cases, strong operational practices are what help organizations catch issues before they become security incidents.

At SEAM, we regularly work with organizations reviewing chain of custody procedures, secure data destruction processes, and lifecycle management practices tied to retired IT assets and storage media.

As environments become more complex and distributed, visibility and verification continue becoming just as important as the technology itself.
