What To Do If Your Getting Hacked: A Step-by-Step Guide for Businesses

Realizing that your business network has been breached is an incredibly stressful experience. You might see a strange pop-up demanding a ransom, notice files disappearing, or receive reports of spam emails coming from your account. In these moments, panic is a natural reaction, but a calm, organized response is what will save your business. Knowing exactly what to do if your getting hacked can mean the difference between a minor disruption and a catastrophic loss of data.

Since 1980, CTS Companies has helped businesses navigate their technology challenges. While technology changes, our commitment remains the same: we help you figure out which technology you need to solve business problems in a simple and reliable way. If you find yourself in the middle of a cyber attack, here is a straightforward, human-centered guide on how to contain the threat, recover your data, and protect your business moving forward.

Immediate Steps: How to Stop an Active Cyber Attack

Time is your most valuable resource during a security breach. When you notice suspicious activity, your primary goal is containment. You need to stop the attacker from moving further into your network or exporting sensitive information.

Isolate the Compromised Systems

If you know which computers, laptops, or servers are acting strangely, you must isolate them immediately. Unplug the Ethernet cables from the back of the machines and turn off their Wi-Fi connections. Do not power the computers down entirely unless your IT professional specifically tells you to do so. Leaving the machine powered on preserves the volatile memory, which security experts use to track how the hacker gained entry.

Disconnect Your Network from the Internet

To prevent the attacker from stealing more data or sending further malicious commands to your network, you need to sever the main internet connection. Unplug your primary router or modem. We understand that this step will disrupt your normal business operations, phone systems, and daily work, but it is a necessary action to stop the bleeding and protect your sensitive client and company information.

Assess the Damage and Secure Your Environment

Once you have contained the immediate threat by taking your systems offline, you need to figure out what happened and lock down your remaining, unaffected systems.

Reset Passwords and Update Credentials

You must assume that the hacker has accessed your passwords. Use a completely separate, uncompromised device, like a personal smartphone on a cellular network, to change the passwords for all critical business accounts. This includes your email platform, financial accounts, and administrative logins for your network. If you do not already have multi-factor authentication in place, turn it on immediately. This requires a second form of verification, like a text message code, making it much harder for criminals to log back in.

Scan for Malware and Ransomware

Hackers rarely leave a system the way they found it. They often install malicious software to maintain access or encrypt your files. You need to identify the specific type of attack you are facing. If your files are locked and a screen appears demanding payment, you are dealing with a ransomware attack. Resolving this requires specialized knowledge and tools.

Engage Your IT Support and Cybersecurity Experts

Handling a network breach is not a do-it-yourself project. Bringing in experienced technology professionals ensures that the threat is fully eradicated before you bring your systems back online.

Contact Your Help Desk or Support Team

Reach out to your internal IT department or external support team right away. They will have specific incident response protocols ready to execute. At CTS Companies, we offer a mix of support solutions, including full on-site members, bulk rates, and reactive support. You can choose the option that best suits your business. If you need reliable, responsive help desk support in Michigan, we have the resources to guide you through a crisis.

Consult a Managed Service Provider

If your current IT setup is overwhelmed by the attack, it is time to consult a dedicated technology partner. A managed service provider in Michigan can take the burden off your shoulders. We can run point on the investigation, communicate with the necessary authorities, and help you navigate the complex process of getting your business back on its feet.

Execute Your Data Backup and Recovery Plan

A successful recovery relies heavily on how well your data was backed up before the hack occurred. You cannot simply turn the internet back on and hope for the best.

Identify the Last Clean Backup

Your IT team will need to review your backup logs to locate the most recent backup that took place before the hacker gained access to your system. Restoring your network from an infected backup will simply restart the cycle of the attack, putting you right back where you started.

Restore Clean Data and Rebuild

Once the network is completely scrubbed of all malware and the vulnerabilities that allowed the hacker in are patched, you can begin restoring your files. Whether you decided to implement on-site storage, off-site storage, or a mix of both, having a reliable continuity plan is vital. We have specialized in data backup and recovery in Michigan since the late 90s, utilizing data centers on both the east and west sides of the state to ensure your information is safe and recoverable.

Prevent Future Hacks: Strengthening Your Defenses

After the crisis is resolved and your business is operational again, you must take steps to ensure an attack like this does not happen again. A breach often highlights the weak points in your IT infrastructure.

Implement Comprehensive Security Policies

Security runs through nearly every decision an IT manager makes. At CTS Companies, we look at security through the lens of six distinct categories to build a strong, layered defense:

• Physical Security: Ensuring server rooms are locked and unauthorized individuals cannot access your hardware.
• Password Policies & Procedures: Enforcing long, complex passwords that are changed regularly.
• Other Policies & Procedures: Establishing clear rules on who has access to specific company data and how that data is handled.
• Antimalware: Deploying modern, updated software to catch viruses and malicious programs before they execute.
• Remote Access: Securing the connections your employees use when working from home or on the road.
• Web Filtering: Blocking access to known malicious websites that often harbor malware.

Addressing all six of these areas creates a robust defense system that is incredibly difficult for criminals to bypass. For a complete evaluation of your current defenses, consider upgrading your cybersecurity in Michigan with our expert team.

Partner with a Premier IT Provider in Michigan

Recovering from a cyber attack is a difficult process, but finding the right technology partner shouldn’t be. Since 1980, we have built our reputation on helping businesses find simple, reliable solutions to complex problems. While some companies force you into one specific type of partnership, we deliver across a spectrum, ranging from one-off recovery projects to acting as your full IT department.

Beyond security and support, we also understand the importance of clear communication during and after a crisis. If you are looking to upgrade your communication infrastructure without a massive upfront cost, we offer managed voice services that provide modern functionality while removing technical worries. Alternatively, if you prefer to purchase an on-premise voice system up front without a monthly cost, our traditional PBX systems are an excellent choice.

Technology should make your business run smoother, not keep you awake at night.
