AnyDesk disclosed on February 2, 2024 that an investigation had found evidence of compromised production systems. The company said it activated a response plan with CrowdStrike, notified authorities, revoked security certificates, replaced affected systems where necessary, and that the incident was not related to ransomware. This is a historical disclosure—not evidence of a newly discovered 2026 compromise.
What happened to AnyDesk?
AnyDesk said a security audit, prompted by indications of an incident, identified compromise in production systems. Its February 2, 2024 statement said the remediation and response plan had concluded successfully and that relevant authorities had been notified.
The company said it revoked security-related certificates and was replacing its previous code-signing certificate. It also said its systems were designed not to store private keys, security tokens, or passwords that could be used to connect to customers’ end-user devices.

Why were AnyDesk passwords revoked?
AnyDesk revoked passwords for the my.anydesk.com web portal as a precaution. The action concerned portal accounts. It does not, by itself, establish that every AnyDesk client credential, remote session, or end-user computer was compromised.
AnyDesk recommended changing the password anywhere else it had been reused. Reuse turns a portal credential incident into a broader account-takeover risk, so a replacement password should be unique and long. A password manager is optional, but can make unique credentials practical.

Was my computer affected?
The available public statement did not establish that customer computers were compromised, and AnyDesk said it had no evidence of affected end-user devices at the time. The reviewed sources also do not publish a verified count of affected customers, accounts, or devices.

What risks did CERT-FR identify?
CERT-FR described potential confidentiality loss and malicious remote control as risks. Its alert said source code, certificates, and private keys could have been stolen and noted that AnyDesk had reported two affected European relay servers.
The alert discussed possible later interception or tampering scenarios, but explicitly said it could not confirm their likelihood or complexity. Those are risk scenarios, not proof that customer sessions were intercepted.

Which AnyDesk versions were affected?
CERT-FR’s alert, last updated April 15, 2024, gave historical thresholds for versions signed before replacement certificates were used:
Free tools Windows power users keep installed
One-click scans. No signup required.
| Deployment | Historical threshold in the CERT-FR alert |
|---|---|
| Windows installable and portable | Versions signed before 8.0.8 and 7.0.15 |
| macOS installable | Versions signed before 8.0.0 |
| Custom or on-premises clients | Clients not regenerated to the versions specified by CERT-FR |
| Other versions | CERT-FR said it was awaiting more information |
These cutoffs are historical alert guidance, not a current “safe version” promise. Check AnyDesk’s current release and security guidance before choosing an update. The company advised using the latest version carrying the new code-signing certificate; do not treat a 2024 version number as the current supported release without verifying it.

What individual users should do
- Change the password for the my.anydesk.com portal if you still use it, and replace that password anywhere it was reused.
- Download and install AnyDesk only from the official AnyDesk source, following the vendor’s current release guidance.
- Review account and device activity for unfamiliar access, unexpected sessions, or unexplained configuration changes.
- If you find suspicious activity, disconnect or contain the affected system as appropriate, preserve evidence, and seek qualified incident-response assistance.
What IT teams should check
CERT-FR recommended treating the response as an inventory, authorization, risk, and evidence-preservation exercise.
- Inventory every AnyDesk installation, including mobile fleets, custom clients, and on-premises deployments.
- Confirm that each installation is legitimate, authorized, and still required.
- Determine the sensitivity and business criticality of systems reachable through AnyDesk, along with operational constraints.
- Before upgrading where practicable, preserve system, application, and network logs so later investigation is possible.
- Renew passwords used to connect to AnyDesk instances.
- Search for suspicious activity dating from December 20, 2023, including platform-specific traces and connection logs listed by CERT-FR.
- Update software under current vendor guidance. Depending on risk and business constraints, consider removing unpatched AnyDesk installations and using an alternative.
- For suspected compromise, engage a qualified incident-response provider.
How to interpret the incident today
The strongest established facts are limited but clear: production systems were compromised according to AnyDesk’s February 2, 2024 disclosure; portal passwords were revoked as a precaution; certificates and systems were remediated; and AnyDesk reported no evidence of affected end-user devices at that time.
Those facts should not be expanded into an unsupported breach count, a claim that every customer was exposed, or a claim that remote sessions were intercepted. Organizations should use current AnyDesk guidance for live version status and apply the CERT-FR alert’s investigation steps when reviewing historical exposure.
