If your website has been hacked, you should stay calm, have all access credentials changed, inform your hosting provider, preserve existing backups and have it checked whether a data breach notification obligation applies. Nano Concepts analyzes the incident, removes malware or restores the website from a clean backup, closes the cause, hardens the system and checks it again afterward. Depending on scope, this falls under the Starter package from €2,500 or, for complex stores and web applications, the Professional package from €8,000 – the exact quote follows after the free initial consultation.

Hacked website repair with Nano Concepts

Your website has been hacked – what should you do? First: stay calm and act deliberately, because deleting things in haste often destroys the traces needed to find the cause. Have all access credentials for the website, hosting, database and email changed, inform your hosting provider and preserve existing backups before they are overwritten automatically. Also clarify with your legal or data protection advisor whether a notification obligation applies – this does not replace legal advice. After that, we take over: we analyze the incident, repair the hacked website and close the route the attack came through.

01

Typical signs are foreign content or links, redirects to dubious sites, new administrator accounts, spam sent from your server or a security warning from Google in the browser. WordPress websites with outdated plugins or themes are frequently affected. We determine what was changed, remove malware, foreign content and hidden backdoors and – where possible – restore the website from a clean backup. Whether and how completely data can be restored depends on the condition of the existing backups; nobody can seriously give a guarantee for that.

02

A cleanup alone isn't enough: if the cause remains open, the same attacker can come back at any time. That is why we update the CMS, plugins and server components, harden logins and access rights and set up monitoring. If Google has flagged your website as dangerous, we support you in requesting a review through Search Console after the cleanup – however, when the warning disappears and whether rankings recover completely is for Google to decide. At the end, you receive documentation of the incident and all measures taken.

Scope of services

What we deliver for you

Analysis, cleanup and restoration of hacked websites – including root-cause investigation and protection against new attacks.

Initial analysis & preserving the state

We secure the current state for analysis and determine which files, database entries and user accounts were changed.

Malware removal & cleanup

Malicious code, foreign content, spam pages and hidden backdoors are removed – with WordPress, also in plugins, themes and uploads.

Restoration from a clean backup

Closing the cause

We identify the entry point, such as an outdated plugin or a compromised account, and close it permanently.

Hardening & new credentials

New access credentials, two-factor login, tidied user accounts, up-to-date software and secure server settings.

Follow-up check & Google warning

We check the website again after the cleanup and support you with the review request if Google shows a security warning.

FAQ

Frequently asked questions about Hacked website repair

Stay calm and don't delete anything in haste, so that the cause remains traceable later. Have all passwords for the website, hosting, database and email changed, inform your hosting provider and preserve existing backups. Have it checked whether a notification obligation under GDPR applies – this does not replace legal advice – and contact us for analysis and cleanup.

Typical signs are foreign content or links, redirects to other sites, unknown administrator accounts, spam sent from your server, or warnings from Google and your hosting provider. Some attacks remain invisible to visitors and only show up in search results or in Search Console. If you are unsure, we check your website and tell you whether an incident has actually occurred.

That depends on how deep the attack goes, whether clean backups exist and how extensive the website is. Depending on scope, cleaning up and securing a company website can fall under the Starter package from €2,500, and complex stores or web applications under the Professional package from €8,000. You will receive the exact quote after the free initial consultation, in which we assess the situation.

It's best to call us directly – we respond quickly by arrangement and clarify in the first conversation when we can start. How long the cleanup takes depends on the extent of the attack and the condition of the backups. After the analysis, we give you a concrete timeframe.

Yes. We check core files, plugins, themes, uploads, database and user accounts, remove malware and hidden backdoors and bring all components up to date. Then we secure logins and permissions so that the same route cannot be used again.

That is a legal question that depends on the individual case, for example on which data is affected, what was agreed by contract and what protective measures were in place. Please clarify liability questions with your legal counsel. This does not replace legal advice. On the technical side, we support you with traceable documentation of what happened and which measures were taken.
