What to Do If You Think You’ve Been Hacked
Something’s off. Your computer is acting weird, your phone battery is draining unusually fast, or you received a suspicious login alert. If you’re asking, “Have I been hacked?”, this step-by-step guide explains what to do next to limit the damage and start recovering.
Think you’ve been hacked? Don’t panic. The most important thing is to act quickly and avoid giving an attacker more time to access your accounts, devices, or data.
Your computer may suddenly behave strangely. Your phone battery may drain unusually fast. You may receive a suspicious login notification from your email, Facebook, or another important account. These signs do not always mean you have been hacked, but they should never be ignored.
Disconnect From the Internet
If you think your device is actively compromised, disconnect it from the internet as quickly as possible. This can help prevent an attacker from maintaining remote access or communicating with malware already running on the device.
- Unplug the Ethernet cable: Physically disconnect wired internet access from the device.
- Turn off Wi-Fi: Disable Wi-Fi or enable airplane mode when appropriate.
- Power off if needed: If the device is behaving dangerously or you suspect active remote access, shut it down.
If you’re a business using shared drives, remote access, or connected workstations, consider disconnecting affected devices and getting professional guidance before bringing them back online.
Change Your Passwords Immediately
If an attacker may have stolen your credentials, change your most important passwords using a different, trusted device. Start with the accounts that could give an attacker access to your money, identity, communications, or other systems.
Use strong, unique passwords and never reuse the password that may have been compromised. If the same password was used on multiple accounts, change it everywhere it was used.
Changing a password is only one part of account recovery. Review active sessions, recovery email addresses, phone numbers, forwarding rules, and multi-factor authentication settings for signs that an attacker changed your account configuration.
Run a Deep Scan, or Let Us Do It for You
Standard antivirus scans can be useful, but they may not identify every type of compromise. If you suspect that someone is watching your device or maintaining hidden access, a professional malware and spyware investigation may be necessary.

Document What Happened
Before deleting everything or resetting the device, document what you observed. These details can help identify the source of the incident and may become important for business compliance, insurance, or client disclosure requirements.
- Record the symptoms: Write down exactly what looked unusual.
- Note when it started: Record when you first noticed suspicious activity.
- Save unusual messages: Keep suspicious popups, emails, login alerts, and other evidence.
- Identify affected devices: Record which computers, phones, or other devices may be involved.
- List potentially affected accounts: Include email, financial, social, and business accounts.
Save screenshots of unusual messages, errors, login alerts, or account activity. Even small details can help during a cybersecurity investigation.
Secure Other Devices
If one device was compromised, other devices connected to the same home or business network may also be at risk. Do not assume that the problem is limited to the first computer or phone you noticed.
- Scan computers and phones: Check other devices for malware or suspicious activity.
- Update software: Install current operating system, browser, and security updates.
- Secure your router: Reboot the router and change the Wi-Fi password if compromise is suspected.
- Check connected devices: Review printers, cameras, thermostats, and other smart devices.
Vector Shield offers full-system cleanups and device audits for home users, seniors, and business teams, with remote or on-site support.
Get Ongoing Protection, Not Just a One-Time Fix
Once an attacker has gained access, a simple cleanup may not be enough. The goal should be to identify how the compromise happened, remove the threat, secure the environment, and reduce the chance of another incident.
