How Do Hackers Break Into CCTV Cameras and Smart Devices?
Last month a family in Ohio woke up to find their baby monitor speaking in a man’s voice. The camera slowly turned toward the crib while the stranger said, “I’m watching you sleep.” The parents ripped the device off the wall, but the damage was done. Their $79 camera from Amazon had been on the internet for six months with the default password “123456”. The attacker was sitting in another country, drinking coffee, and browsing thousands of cameras just like theirs. In 2025, over 100 million CCTV cameras and smart devices are accessible from the public internet. Most of them are waiting to be discovered by a simple Google search or automated scanner. This post explains exactly how hackers get in, shows the scariest real-world examples, and gives you a simple checklist so this never happens to you or your family.

Why Cameras and Smart Devices Are So Easy to Hack
- Manufacturers prioritize price over security
- Default passwords are often “admin” or “12345”
- Many devices never receive security updates
- They are directly exposed to the internet (no firewall)
- Weak or no encryption on video streams
- Old software from 2015 still running in 2025
The 9 Most Common Ways Hackers Break In
| Method | How It Works | Skill Needed | Time to Hack |
|---|---|---|---|
| Default credentials | Try admin/admin, 123456, etc. | None | Seconds |
| Shodan / ZoomEye search | Google for internet-connected devices | Beginner | Minutes |
| Credential stuffing | Use leaked passwords from other breaches | None | Automatic |
| Known vulnerabilities | Exploit old firmware bugs | Medium | Hours |
| UPnP exposure | Device opens its own port on router | None | Instant |
| Cloud account takeover | Hack your email → access all cameras | Low | Days |
| Man-in-the-middle on public Wi-Fi | Sniff unencrypted streams | Medium | Live |
| Brute force | Guess weak passwords | None | Minutes to hours |
| Supply-chain firmware attack | Backdoor added at factory | Advanced | Already inside |
Terrifying Real Cases from 2024–2025
- 2025: Hacker watched a family in Singapore for months through eight cameras
- 2024: Ring cameras in eight U.S. homes hijacked, racial slurs shouted at children
- 2025: German family’s baby monitor played loud porn at 2 a.m.
- 2024: Swatting attacks used hacked cameras to fake emergencies
- 2025: Creep streamed 2,000+ private cameras on adult websites
How Hackers Find Your Devices in Minutes
- Shodan.io: “Google for devices” – search “webcam” + your city
- Censys, ZoomEye, BinaryEdge: scan the entire internet daily
- Insecam.org and similar sites stream live feeds
- Botnets like Mirai automatically infect everything with default passwords
10 Simple Steps to Lock Down Your Devices
- Never leave default passwords (change immediately)
- Disable UPnP on your router (most important!)
- Put cameras on a separate guest/IoT network
- Turn off “remote access” or “cloud viewing” if you don’t need it
- Use strong, unique passwords + MFA on cloud accounts
- Buy cameras that support firmware updates for at least 5 years
- Cover indoor cameras when not in use
- Block outgoing internet for devices that only need local control
- Check Shodan.io for your IP once a month
- Replace any device from unknown Chinese brands
Which Brands Are the Worst (and Best)
Worst (avoid):
- Most $20–$50 no-name Amazon cameras
- Older Hikvision/Dahua (unless patched)
- Eufy (after 2023 encryption scandal)
- Wyze (multiple breaches)
Best (2025):
- Google Nest (automatic updates, good encryption)
- Apple HomeKit Secure Video cameras
- Arlo Ultra series (if you disable cloud)
- Reolink (local storage, no cloud needed)
The Future: Better or Worse?
Getting better:
- EU/UK ban default passwords from 2025
- Matter and Thread standards force local control
- Big brands finally adding auto-updates
Still bad:
- Billions of old devices will stay online forever
- New cheap brands appear every week
- AI will make voice spoofing and deepfake camera feeds worse
Conclusion
Your CCTV camera or smart device is not a toy. It is a window into your home that anyone on the planet can open with a few keystrokes. Hackers don’t need to be geniuses. They just need you to skip one simple step.
Do the basics today: change passwords, disable UPnP, isolate devices. It takes 15 minutes and stops 99% of attacks. Your family’s privacy is worth far more than the convenience of watching your dog from work.
Can someone really hack my camera in minutes?
Yes, if it has default credentials or is exposed via UPnP.
Is my Ring or Nest safe?
Much safer than cheap brands, especially with 2FA and updates.
Do I need to throw away my old camera?
If it can’t change password or update firmware, yes.
What is UPnP and why disable it?
It lets devices open ports automatically. Hackers love it.
Are wireless cameras worse than wired?
Not if configured right, but wireless ones often ship with UPnP on.
Can hackers see me if the camera is off?
Sometimes yes. Many “off” cameras still listen or record.
Is local storage safer than cloud?
Yes. No internet = no remote hack.
Do baby monitors get hacked a lot?
Yes. They are one of the most common targets.
Is it safe to buy used cameras?
Never. They may already be infected.
Will a VPN protect my cameras?
Only if you put the whole house behind site-to-site VPN.
Can someone listen through my smart TV camera?
Yes. Cover it or disable the mic in settings.
Are 4K cameras safer?
No. Resolution has nothing to do with security.
Do hackers sell access to cameras?
Yes. “Private” feeds sell for $1–$50 on dark web forums.
Is Hikvision banned for a reason?
Yes. Backdoors and poor security led to bans in many countries.
Can I check if my camera is hacked?
Look for strange activity, LED behavior, or use a network monitor.
Should I tape over indoor cameras?
Yes, or buy ones with physical shutters.
Are Reolink cameras safe?
One of the best for privacy. Local storage, no cloud required.
Will laws stop this?
Slowly. EU/UK are leading; most countries are behind.
Best single action today?
Log into your router right now and turn off UPnP.
Final thought?
If you wouldn’t leave your curtains open 24/7, don’t leave your camera open to the internet.
