Tech Support Scam Prevention: How to Spot Fake ISP Calls Requesting Remote Access
Learn how scammers impersonate Comcast, AT&T, and other ISPs to trick you into granting remote access. Here's how to protect yourself.

Tech Support Scam Prevention: Spotting Fake ISP Calls
"This is Comcast technical support. We've detected malware on your network and need to remotely access your computer to fix it." If you get a call like this, hang up immediately — it's a scam that costs Americans billions of dollars every year.
How the Scam Works
The Typical Script
- The call: "This is [Comcast/AT&T/Verizon] technical support. We've detected a problem with your connection."
- Creating fear: "Malware detected", "Hacking attempt in progress", "Personal data at risk"
- Remote access request: "Please install TeamViewer/AnyDesk so we can fix the issue"
- Malware installation: Once connected, they install keyloggers, backdoors, or spyware
- Payment demand: "Security software license fee" or "network upgrade charge"
Common Variations
| Variation | Approach |
|---|---|
| Refund scam | "You were overcharged, we need your bank details to process a refund" |
| Speed upgrade | "Free speed upgrade available" — then installs malware via remote access |
| Government audit | "Mandatory security compliance check" — collects personal information |
| Contract expiry | "Your service will be disconnected if you don't renew now" — demands payment |
5 Key Signs It's a Scam
1. Your ISP Won't Call First
Comcast, AT&T, Spectrum, and Verizon do not proactively call customers to request remote access. Any unsolicited call about "malware on your network" is a scam.
2. Remote Access Software = Red Flag
No legitimate support operation asks you to install TeamViewer, AnyDesk, or similar tools over an unsolicited phone call.
3. Don't Trust Caller ID
Caller ID can be spoofed easily. Even if the number shows up as your ISP's official number, it could be faked. Hang up and call back using the number on your bill.
4. Payment Requests = Scam
Your ISP will never ask for credit card numbers or bank details over an inbound phone call.
5. Manufactured Urgency
"If you don't act now, your data will be compromised." Legitimate technical issues don't require immediate panic-driven action.
Real Victim Stories
- A retired teacher in Ohio granted remote access to "Spectrum support" — lost $15,000 from her bank account
- A couple in Florida installed AnyDesk for "AT&T security check" — identity theft and credit card fraud followed
- A senior in Texas paid $500 for "antivirus installation" via a fake Comcast call
What to Do When You Get a Suspicious Call
- Hang up immediately — don't engage in conversation
- Call your ISP directly using the number on your bill or their official website
- Tell family members — especially elderly relatives who are more vulnerable
- Report the call — FTC (reportfraud.ftc.gov) or FBI IC3 (ic3.gov)
If You Already Granted Remote Access
- Disconnect from the internet immediately (unplug ethernet or disable WiFi)
- Don't shut down the computer — contact a professional for malware removal
- Change all passwords from a different, clean device
- Contact your bank and credit card companies to freeze transactions
- File a report with local police and the FTC
Protecting Elderly Family Members
Seniors are the primary targets. Have this conversation with them:
- "If someone calls saying they're from the internet company, never let them access your computer"
- "If they ask you to install any program, hang up and call me first"
- "Never give passwords or card numbers over the phone"
When sharing security-related information with family, use LOCK.PUB's password-protected memo instead of sending it through iMessage or Messenger where it stays in chat history permanently.
When You Have a Real Technical Issue
If you're actually experiencing internet problems:
- You initiate the call to your ISP's official support number
- Use your ISP's official app to schedule a service visit
- Check your ISP's status page for known outages in your area
Final Thoughts
Tech support scams are becoming increasingly sophisticated, but the core rule is simple: if your ISP calls you first and asks for remote access, it's a scam — 100% of the time. Remember this one rule and share it with vulnerable family members. For securely sharing passwords and security information with your family, use LOCK.PUB instead of leaving sensitive data in chat messages.
