On January 11, a malicious file was uploaded to Playbook and shared with a limited number of users via publicly accessible Shared Pages. Within a few hours, automated scanners - including VirusTotal - identified and flagged the link as malicious.
However, some malware protection tools with stricter policies applied a domain-level restriction rather than blocking the specific file. As a result, the entire Playbook hosting proxy domain was blocked.
While we fully understand the importance of preventative security measures and user safety, we believe this response was overly restrictive - comparable to blocking Google because a single user shared a malicious file. Since then, we have been working methodically with all vendors whose software blocked Playbook, and all known issues have now been resolved.
To prevent similar situations in the future, we are introducing stricter file-scanning policies on our end. In addition, we have deployed a backup hosting proxy to ensure continued access to Playbook should a similar issue arise again, minimizing the risk of service disruptions.
