We share more of our lives online than ever before, from family holidays to first day of school photos, social media has become the scrapbook of modern life. But while these posts seem innocent, they can reveal far more than you think and cybercriminals are paying attention.
At Commercial Networks, we often warn businesses about oversharing company details on LinkedIn or staff profiles. Yet the same risk applies at home. When parents post photos of children in school uniforms, share pet names, or reveal birthdays, they’re unknowingly giving hackers valuable clues. This practice is commonly known as sharenting and it has serious cybersecurity consequences.
What Hackers Learn from Social Media Oversharing
Hackers use a technique called OSINT (Open Source Intelligence) to piece together information from publicly available sources. Every detail you share online can be added to the puzzle. Here’s what they look for:
- School information – A child’s uniform or a “first day” sign can reveal exact locations and routines.
- Pet names – Commonly used in passwords and security questions.
- Birthdays – Perfect for guessing passwords or identity theft.
- Location tags – Indicate when you’re away from home, creating physical as well as digital risks.
- Family members’ names – Useful for crafting convincing phishing or impersonation attacks.
As the NCSC explains, attackers can combine these small details to mount highly targeted cyberattacks.
The Cybersecurity Risks of Sharenting
Oversharing doesn’t just affect individuals, it creates vulnerabilities for businesses too.
- Password Cracking
Attackers use personal details like pet names or birthdays to guess passwords and bypass weak authentication. - Phishing Scams
Armed with background information, hackers can craft highly convincing emails that appear genuine. - Identity Theft
Full names, dates of birth and school details can be used to apply for credit or services fraudulently. - Physical Safety
The NSPCC warns that revealing a child’s school or daily routine can put their personal safety at risk, even before you consider the digital dangers.
How Businesses Are Affected by Sharenting
It’s easy to assume oversharing is just a personal issue, but businesses are exposed too. Employees who share personal details online can unknowingly help cybercriminals launch targeted attacks such as whaling or business email compromise (BEC).
The FBI highlights that BEC scams have cost global businesses over $26 billion, and much of that success comes from criminals using information found in public posts to make their emails look more convincing.
For example, if a hacker knows your finance manager is away on a family holiday (thanks to Instagram), they may time a fake invoice request to slip through while they’re out of office.
How to Stay Safe Online
The good news? Awareness is the first step. By adjusting behaviours and settings, both individuals and businesses can protect themselves.
- Think Before You Post – Ask yourself if the information could help someone guess a password, security answer, or routine.
- Lock Down Privacy Settings – Limit who can see posts, especially photos of children (Internet Matters has tips).
- Educate Employees – Staff training should include the risks of oversharing online.
- Use Strong Passwords – Avoid personal details; use random passphrases and a password manager.
- Enable Multi-Factor Authentication (MFA) – Add an extra layer of protection to all accounts.
Why Security Culture Matters
At Commercial Networks, we believe the issue isn’t just weak passwords or old software, it’s culture. Employees and families alike need to understand how digital habits can expose them to risk. By encouraging safer sharing online, you strengthen your first line of defence: people.
Conclusion
Sharenting may seem harmless, but in reality, it hands cybercriminals the clues they need to target both individuals and businesses. From guessing passwords to launching phishing attacks, oversharing makes their job easier.
By thinking twice before posting, tightening privacy settings, and promoting a culture of awareness, you can keep your family and your business safe.
