Company network hacked
Unknown access inside the network, locked accounts, unusual traffic. We contain the intrusion, examine domain controllers and credentials and close the entry point.
IT emergency line for the Heinsberg district
Stay calm: the first minutes decide how much damage remains. Wasacon from Heinsberg stops attacks in progress, preserves evidence and brings your systems back into operation in an orderly way.

First aid in an IT emergency
Five steps before anyone starts repairing. They take a few minutes and preserve evidence, data and backups.
Do not log in, do not open anything, do not experiment. Every action can overwrite traces or help the malware along.
Pull network cables, disconnect Wi-Fi, cut remote access. Avoid switching machines off: a running system holds volatile evidence.
Leave emails, files and alerts untouched. Even a ransom note is a piece of evidence.
A hasty reinstall destroys the traces that reveal the entry point and the extent of the attack, and it can endanger intact backups.
Describe briefly what happened and how many systems are affected. We will agree the order of the next steps together.
And right after that:
In an acute case, calling is the fastest way.
Situations we take over
Every incident follows its own pattern. These are the situations we handle most often, on site in the Heinsberg district and remotely beyond it.
Unknown access inside the network, locked accounts, unusual traffic. We contain the intrusion, examine domain controllers and credentials and close the entry point.
Files are encrypted and a ransom note has appeared. We isolate affected systems, protect the backups and assess the recovery options with you.
Foreign sign-ins, new forwarding rules, mails sent in your name. We lock accounts, remove rules, review sign-in logs and secure the accounts.
Windows Server, Active Directory, NAS or virtual environments behave suspiciously. We examine services, accounts and shares and separate compromised systems from the rest.
Defaced pages, malicious code, spam sending or browser warnings. We take the site offline in a controlled way, clean it and close the exploited gap.
Credentials surface in the wrong hands or in a leak. We reset in an orderly sequence, starting with the critical accounts, and switch on a second layer of protection.
Internal data is circulating outside the company. We establish which systems are affected and where the data came from, and document the findings verifiably.
A deceptively genuine mail, a supposed instruction from the boss, a payment to the wrong account. We check what was clicked and secure accounts and payment paths.
A machine behaves strangely, the antivirus raises alerts, something unknown runs in the background. We analyse the infection, remove it and check whether it has spread.
Your situation is not listed? Report it anyway.
Report a cyber emergencyHow the response runs
An emergency response follows a fixed sequence. The goal is to stop the attack, preserve evidence and bring operations back in an orderly way.
What is affected, since when, what is still running? A first picture and a clear order of steps emerge on the phone within minutes.
Compromised systems are isolated, credentials locked, attackers shut out. The damage stops growing.
Logs, accounts and systems are examined: entry point, time frame, affected data. Traces are preserved before they disappear.
Malware and backdoors are removed, systems are rebuilt where necessary, and access is reissued cleanly.
Operations return to the network step by step. You receive comprehensible documentation of the incident and the measures taken.

In the middle of an incident? Report the situation and we take over the sequencing.
Report a cyber emergencyThe direct line
Describe briefly what happened. In an acute case calling is fastest, and the form reaches us as well.
Back into operation
After the attack, what matters is what can be restored cleanly. We check backups before anyone touches them and rebuild in the right order.
Are the backups complete, readable and free of malware? We establish that before any restore begins, so that nothing infected comes back.
First the systems the business depends on: order processing, email, telephony. Then the rest, in sequence rather than all at once.
Rebuilding on cleaned or freshly installed systems, with new credentials and closed gaps, so the attacker does not move back in.
After the restart we verify that everything is there and stays there: data, permissions, backup runs. Only then is the incident technically closed.
Unsure about your backups? That is exactly where we start.
Report a cyber emergencyWhen data is affected
If personal data could be affected, you quickly need a reliable picture. Wasacon supports you with the technical assessment and documentation of a possible data protection incident.
Unsure whether data is affected? The analysis settles that.
Which systems and data were reachable, over what period, by what route? We compile the technical facts on which every further evaluation is built.
Timeline, affected systems, measures taken: a comprehensible basis for your internal evaluation and your reporting channels.
The GDPR sets short deadlines for notifiable incidents. The legal evaluation rests with your data protection officer or legal counsel, and we supply the technical basis for it.
Harden instead of hope
The second attack often hits the same gap. After recovery we harden the environment exactly where the incident showed it to be vulnerable.

Stolen passwords lose their value when every sign-in needs a second factor. We introduce MFA where it counts.
Rules that match the business, VPN instead of open ports, controlled remote access. What is reachable from outside becomes a deliberate decision.
Whoever reaches one segment no longer reaches everything. Production, administration and guests are separated, critical systems especially.
Backups following the 3-2-1 rule, one copy of them immutable, and restores that are tested rather than merely configured.
Endpoints and network are monitored continuously, so that a new attempt is noticed while it is still small.
Rather before than in the middle of it? Ask for a review of your environment.
Report a cyber emergencyWhere we operate
The office is in Heinsberg and remote access is available at once. On site we cover the whole district.
Towns in the service area
Just outside the district? Call anyway, distance does not matter for remote access.
Answered briefly
The questions that come first in a crisis, answered before you have to search.
Not hastily. Payment guarantees neither decryption nor the deletion of copied data, and it finances the next attack. We first check what backups and known decryption tools can deliver, and we recommend reporting the incident to the police.
Disconnect yes, switch off preferably not. A running system holds volatile traces that a forensic analysis needs. Pull the network cable and leave the machine on until specialists take over.
Typical signs are sign-ins at unusual times, locked accounts, new forwarding rules in mailboxes, suddenly slow systems, antivirus warnings, or files that have been moved or encrypted. When in doubt, call briefly and the check brings clarity.
That depends on the extent and cannot be stated seriously as a flat figure. In the first conversation we narrow down the situation and the approach, so you know what to expect before anything starts.
Yes. A great deal can be contained and analysed remotely at once. When hands on the machine are needed, we come to your site anywhere in the Heinsberg district.
Yes. The IT emergency line is also open to companies that Wasacon does not yet look after. Whether ongoing support follows after the response is entirely your decision.
That depends on the data affected. If personal data is involved, the GDPR sets short deadlines for notification. The decision rests with your data protection officer or legal counsel, and we supply the technical documentation for it.
