Website Incident Response

Some incidents announce themselves. Your homepage has been replaced with an attacker’s message, or the browser throws a red “deceptive site” warning. Others are quieter and more dangerous: visitors report being redirected to gambling or pharma pages, your host suspends the account for sending spam, unfamiliar admin users appear, or Google Search Console emails you about a hacked-content detection. If any of these are happening, you need website incident response, not another plugin.

The first priority is to stop the bleeding without destroying evidence. Depending on the situation that might mean putting the site into a holding page, isolating it from the database, blocking the attacker’s access, or taking a forensic snapshot before anything is changed. We do not just start deleting files, because the files often tell us how the attacker got in.

Next we work out what happened. We comb the file system for recently modified and injected files, review access and error logs for the request that started it, and check the database for malicious admin accounts and injected content. Once we know the entry point, we remove every piece of the attacker’s foothold: the web shell, the scheduled task, the extra admin, the poisoned theme file. Half-measures here are why some “cleaned” sites come back infected.

With the threat removed, we bring the site back. That usually means restoring known-good code, patching the vulnerability that was exploited, updating the components that were out of date, and rotating every credential the attacker could have seen. Only then does the site go public again, so it comes back closed rather than freshly open. Where a clean backup does not exist, we rebuild the affected components from trusted sources rather than trusting files the attacker could have touched, which takes longer but is the only safe route.

You get a written incident report: what happened, when, how they got in, what we did, and what to change so it does not recur. Where personal data may have been exposed, the timeline and evidence in that report are what you need for a GDPR assessment and any regulator notification. The report also lists the concrete hardening steps we recommend, ordered by how much risk each one removes, so your team knows exactly what to tackle next rather than guessing.

To move quickly we need access and honesty. Hosting or server login, any recent backups you have, and a plain account of what you noticed and when. It helps to know if anything unusual happened recently: a new plugin, a staff departure, a shared password, a phishing email someone clicked. You do not need to have any of it perfectly organised. Tell us what you can and we work with what exists, but the more context we have at the start, the faster containment goes.

Website defacement incident response deals with the most visible attack: your content replaced by an intruder’s message or imagery, often for bragging rights or a political statement. It looks catastrophic and is usually one of the more contained events, but it is a loud signal that someone had write access to your files, so we treat it as a full compromise and hunt for what else they touched.

Quieter and more damaging. The attacker injects code that redirects your visitors, serves malware, or stuffs hidden spam links to manipulate search rankings. Customers lose trust, Google may delist you, and the infection often hides in database records and legitimate-looking files. This is the most common web application incident response case we handle.

The dangerous part of almost every incident. Attackers plant hidden access so they can return even after you “fix” the visible problem. Uploaders disguised as image files, extra administrator accounts, malicious cron jobs, and modified core files all serve this purpose. Removing every trace of persistence is the difference between a real recovery and a temporary one.

A “deceptive site ahead” banner tells every visitor, in the browser’s own words, that you cannot be trusted with their data. That impression outlasts the technical fix. The faster the warning clears and the site returns to normal, the smaller the dent.

If the attacker reached personal data, you may have a legal obligation to assess and report the breach. Under GDPR, a notifiable personal-data breach generally has to reach the supervisory authority without undue delay and within 72 hours of you becoming aware of it. A proper incident report with a clear timeline is what makes that assessment defensible rather than a scramble.

For businesses that cannot afford downtime, a retainer means we already know your environment, hold your recovery details securely, and answer under a pre-agreed SLA. When something happens, there is no cold start; we begin work immediately at a discounted rate. It is the difference between calling a stranger at 2am and calling a team that already has the map.

Fast recovery depends on having a clean point to restore to and knowing quickly when something is wrong. Off-site tested backups and file-integrity monitoring shorten every incident, because we are restoring from something we trust and catching the attack early rather than weeks in.
