Enhanced Canary Files: Strengthening Ransomware Defense
At Covenant Technology Solutions, protecting your environment is our highest priority. We’re continuously advancing our defenses to ensure our clients stay ahead of evolving cyber threats.
This month, we’re rolling out a new security update across our managed environments designed to strengthen ransomware protection, improve system performance, and expand visibility through enhanced Canary File functionality.
What’s New in This Update
We’ve introduced several key improvements to help detect and respond to ransomware faster and more effectively:
- Enhanced Ransomware Detection: Canary Files — the small, harmless “tripwire” files placed throughout your network — have been refined to detect early signs of ransomware activity even sooner. This ensures suspicious behavior is identified before it can escalate.
- Improved Stability: The updated agent enhances system reliability, ensuring consistent operation across a variety of environments and shared directories.
- Expanded Visibility: Canary Files are now deployed in both root and shared directories. This broader placement improves our ability to monitor for malicious activity across your network.
What You Might Notice
You may see new files appear in your shared folders or directories, such as:
E:\SharedData\!1a-Bsdf33444332232.log
E:\SharedData\!invoice-B7E1334222E332.txt
These are safe and intentional. Please do not delete, move, or modify them.
Their presence is a sign that your systems are protected with the latest proactive detection measures.
Note: These Canary Files are purposely designed without external branding, allowing us to integrate these protections seamlessly under the Covenant Technology Solutions umbrella.
Why This Matters
Ransomware tactics are evolving — attackers are increasingly ignoring hidden files, which historically limited early detection.
By making Canary Files visible and strategically positioned, we’ve strengthened their ability to serve as early warning indicators of ransomware behavior.
This allows our security operations team to respond faster, contain threats earlier, and ensure your business continuity remains uninterrupted.
Rollout Timeline
The enhanced Canary File update (Agent Build 2.17.0.4) will begin October 16, 2025, with deployment expected to complete within approximately three weeks.
This rollout will be performed automatically — no action is required on your part.
How You Can Help
To support a smooth rollout and maintain optimal protection:
- Do not modify or delete any Canary Files you see.
- If you accidentally interact with one, contact us immediately.
- Confirm your environment is up to date after the rollout period if desired.
