Aug 25, 20:00:00 GMT+0
Resolved - On August 25, scheduled infrastructure maintenance was performed on parts of our messaging infrastructure.

Type: Incident

Duration: 15 hours

Affected Components:

Aug 12, 15:12:32 GMT+0
Investigating - We are currently experiencing issues with the qualified electronic signature (QES). Some users may incorrectly be asked to upgrade their signature quality or repeat their identification, even though their identification is valid — **no re-identification is necessary.** Signing with other signature qualities (SES/AES) is not affected. The issue is caused by a disruption at one of our partners; we are in close contact with them to resolve it as quickly as possible. We will provide an update as soon as the service is fully restored..

Aug 12, 15:44:56 GMT+0
Investigating - We are continuing to work with our partner on resolving this issue. Clarification on scope: the disruption affects **both** qualified (QES) and advanced (AES) electronic signatures. Affected users may incorrectly be asked to increase their signature quality, repeat their identification, or purchase an identification — even though their identification is valid. No re-identification or purchase is necessary, and already completed signatures remain fully valid. Signing with simple electronic signatures (SES) is not affected. We will provide a further update as soon as the service is restored..

Aug 13, 06:12:33 GMT+0
Resolved - The issue affecting qualified (QES) and advanced (AES) electronic signatures has been resolved, and signing is operating normally again. Users with a valid identification can now sign as expected without being incorrectly prompted to increase their signature quality, repeat their identification, or purchase an identification. No action is required from affected users. All signatures completed during the incident remain fully valid. We apologize for the inconvenience and thank you for your patience while we worked to resolve the issue..

Identified - ### Notice for customers of our German platform ([skribble.de](http://skribble.de)). During this scheduled maintenance window, we will introduce an update to the login process. Going forward, logins and account registrations will be handled by our central, modernised authentication service. This change is an important technical improvement that further enhances the security, stability and future-readiness of the platform. ### What does this mean for you? For most users, no action is required. You will simply notice a slightly updated login and signup experience. The signing experience and all other platform functionality remain unchanged. ### Note for customers using SSO or OIDC integrations on the German platform The authentication flow will now be handled directly by our authentication service. Existing integrations are expected to continue working without any changes. However, if you have implemented custom authentication logic or rely on hardcoded login URLs, we recommend validating your configuration after the maintenance window. **Thank you for your understanding** — we are continuously working to improve the security and reliability of the Skribble platform. \_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_ ### Hinweis für Kundinnen und Kunden unserer deutschen Plattform ([skribble.de](http://skribble.de)). Im Rahmen des geplanten Wartungsfensters führen wir eine Aktualisierung des Anmeldeprozesses ein. Anmeldungen und Registrierungen erfolgen künftig über unseren zentralen,modernisierten Anmeldedienst. Diese Umstellung ist eine wichtige technische Weiterentwicklung, die die Sicherheit, Stabilität und Zukunftsfähigkeit der Plattform weiter verbessert. ### Was bedeutet das für Sie? Für die meisten Nutzerinnen und Nutzer ist keine Aktion erforderlich. Sie werden lediglich eine leicht angepasste Login- und Registrierungsseite bemerken. Das Signieren sowie alle weiteren Funktionen der Plattform bleiben unverändert. ### Hinweis für Kunden mit SSO- oder OIDC-Integration auf der deutschen Plattform Der Authentifizierungsablauf wird künftig direkt von unserem Anmeldedienst abgewickelt. Bestehende Integrationen funktionieren voraussichtlich ohne Anpassung weiter. Sollten Sie jedoch eigene Authentifizierungslogik implementiert haben oder fest hinterlegte Login-URLs verwenden, empfehlen wir, Ihre Konfiguration nach dem Wartungsfenster zu überprüfen. **Vielen Dank für Ihr Verständnis** — wir arbeiten kontinuierlich daran,die Sicherheit und Zuverlässigkeit der Skribble-Plattform zu verbessern..

Nov 3, 16:17:35 GMT+0
Identified - We have identified the source of the issue and **closed the entry point**. To **re-enable AES signing for non-Swiss phone numbers**, we need to **deploy an update**, which is scheduled for **tomorrow morning**. No customer data was at risk: the exploit misused our messaging system to trigger SMS messages, which led to an **automated shutdown** due to unusually high volume. More updates will follow as soon as the deployment is completed..

Nov 2, 11:42:00 GMT+0
Identified - We have identified the issue; it only affects authentication SMS sent to **non-Swiss phone numbers**. Our team is working with our SMS provider to resolve the problem and restore full delivery. We will provide an update as soon as we have more information..

Nov 4, 13:13:28 GMT+0
Resolved - The issue has been **resolved**. All authentication SMS are now **fully operational again**..

Nov 3, 11:25:06 GMT+0
Identified - Due to **fraudulent use of our SMS authentication service**, all authentication SMS to **non-Swiss phone numbers** are currently **blocked** for signing with AES. We are actively investigating the source of the abuse and working to **close the exploited gap**. In the meantime, we recommend using **SES** or **QES** signature levels as alternatives. We will provide an update as soon as we have more information..

Nov 6, 09:01:54 GMT+0
Postmortem - **Incident Summary (31.10.2025 – 03.11.2025)** We experienced abuse of SMS resends in **trial accounts**, where SMS messages were sent to **high-cost numbers outside the EU and CH**. After detection, the **SMS gateway was temporarily deactivated** while we analyzed the issue and implemented countermeasures. **Impact:** * Financial loss to Skribble only * No customer data affected or exposed **Countermeasures:** * Trial (non-paying) accounts can no longer send SMS outside defined “safe” countries * Paying customers remain unrestricted We apologize for the disruption during this period. The temporary outage was necessary to ensure no security breach and to protect our customers from any negative impact. Sincerely, Waldemar Dick (CTO).

Nov 14, 11:13:08 GMT+0
Identified - We have detected new issues with sending authentication SMS to **certain EU countries**. Currently, AES signatures for signers with **German** and **French** phone numbers are **not functioning**. At this stage, we cannot rule out that **additional countries** may also be affected.

Partial Unavailability of Signature Activity and Signature Reports

Mon, 23 Jun 2025 20:00:00 +0000

Type: Incident

Duration: 2 days, 20 hours and 20 minutes

Affected Components: ,

Jun 23, 20:00:00 GMT+0
Identified - After our data center migration, we observed that a backlog of audit events was being processed with delay. Impact: \* The Signature Activity tab in the admin interface displayed audit events with delay. \* Signature Reports, which rely on audit events, are generated partially or not at all if relevant audit data are missing..

Jun 25, 16:40:00 GMT+0
Monitoring - The audit event backlog has been fully processed. All delayed audit entries are now complete and available in the system. The Signature Activity tab in the admin interface is now displaying all audit events correctly..

Jun 26, 16:20:00 GMT+0
Resolved - Fixed Report Cache Signature Reports are signed and cached at the time of generation. As a result, any reports created during the incident window (23.06\. 22:00 – 25.06\. 18:40) may still have remained incomplete even after the audit log was fixed. Mitigation: We have removed all Signature Reports generated during the affected timeframe. These reports will now be automatically re-generated on demand (via UI or API) using the complete and corrected audit data .

Jun 27, 07:23:26 GMT+0
Postmortem - **High-Level Summary** After moving our systems to a new data center, background data that powers some signature reports was delayed. Reports created between Monday evening and Wednesday evening may have been incomplete. We’ve fixed the issue and will automatically re-create any affected reports as soon as they are accessed. **No data has been lost**. Signature reports can be re-created **up to 10 years** into the past at any time. **Technical Details** Following the data center migration, a backlog of audit events accumulated and was only processed with delay between Monday 23.06\. 22:00 and Wednesday 25.06\. 18:40. Impact: * Audit events in the Signature Activity tab appeared with delay. * Signature Reports generated during this window were incomplete or not generated, depending on audit event availability at the time. As of Wednesday 25.06\. 18:40, the backlog was fully processed. All delayed audit events have been restored and are complete. Multiple customers reported incomplete Signature Reports. We conducted a thorough review of the audit logs and the report generation process. The issue was traced to cached reports that had been created while audit events were still delayed. Since Signature Reports are signed and cached at the time of generation, any reports generated during the affected period remained incomplete, even after the underlying audit data had been fully restored. Mitigation 26.07\. 18:20: All Signature Reports generated between **23.06\. 22:00 and 25.06\. 18:40** have been **removed**. When accessed via UI or API, they will now be **automatically re-generated** using the complete and accurate audit data. .
