Cyberattacks don’t always start with a bang. More often, they creep in quietly—gathering data, spreading through your network, and waiting for the right moment to strike. By the time most businesses realize they’ve been compromised, it’s too late.

At CloudCore IT Solutions, we teach clients how to recognize the early warning signs of a cyber incident before it becomes a disaster. Here’s what to watch for and what to do if you suspect something’s wrong.

🚨 1️⃣ Unexpected System Slowdowns

If your systems are suddenly sluggish without explanation, it could be more than an old PC. Malware, crypto-mining software, or data exfiltration processes can silently eat up resources in the background.

What to do: Run antivirus and endpoint protection scans immediately. If multiple systems are affected, disconnect from the network and call your IT provider.

🧾 2️⃣ Strange Account Activity or Login Attempts

If you notice logins from unusual locations, times, or IP addresses—especially outside normal work hours—it’s a major red flag.

What to do:

• Check your account’s security activity (Microsoft 365, Google Workspace, etc.).
• Force a password reset for all affected accounts.
• Enable Multi-Factor Authentication (MFA) if it’s not already in place.

📧 3️⃣ Employees Receiving Unusual Emails

When multiple team members report strange or suspicious emails—especially ones impersonating management, vendors, or clients—you might be dealing with a phishing campaign or business email compromise attempt.

What to do:
Train staff never to click links or open attachments in suspicious messages. Forward them to IT or CloudCore for analysis before interacting.

💾 4️⃣ Missing, Moved, or Encrypted Files

If files disappear, are suddenly encrypted, or their names change, it could indicate ransomware or a data breach in progress.

What to do:

• Disconnect the affected device from the network immediately.
• Do not power it off—this can erase critical forensic data.
• Contact your IT provider or cybersecurity team right away.

🔒 5️⃣ Disabled Security Tools

Attackers often disable antivirus, firewalls, or logging tools to cover their tracks. If you notice these services turning off unexpectedly, assume compromise until proven otherwise.

What to do:
Re-enable protection tools, document what was disabled, and check logs for tampering.

🧠 6️⃣ Unexpected Pop-Ups or Browser Redirects

Unwanted pop-ups, strange ads, or redirected web traffic can indicate adware or spyware infections—especially if multiple browsers or users are affected.

What to do:
Run a malware scan and clear browser extensions. In business environments, your IT provider should audit DNS and proxy logs for deeper issues.
