I recently gave a cyber security presentation about staying safe online. Given all the tools we have to protect ourselves, it’s still difficult to explain why hackers remain a problem.
Here’s how I see it:
We’ve shared a lot: For over 20 years, we’ve been putting our personal stuff on the internet.
Hackers are sneaky: At the same time, hackers have turned our phones and emails into ways to trick us. They use texts and emails to send harmful programs (malware), scams, and other online crimes.
It might sound scary, but that’s the reality we live in now.
How hackers trick us
Many people don’t understand how hackers trick us. They usually don’t write computer code themselves. Instead, they’re like digital con artists. They get people to click on links or give away their private information.
You should already know not to share things like your birthday or where you were born on social media. Also, don’t put organization charts (who works where) on your website. Hackers can use that information to make fake emails that look real.
This trick is called “social engineering.” Hackers find your information on places like LinkedIn and use it to attack your company or family.
These attacks can be simple, like pretending to be your boss and texting you to buy a $100 gift card. Or they can be more serious, like asking you to wire $100,000 by email, pretending it’s for a genuine land deal.
A big problem: When DNA gets hacked
What happens when things get really bad?
Imagine a company that has the DNA of 15 million people. If hackers break into their system, the company could shut down. That’s bad news for customers of a company called 23andMe.
A lot of people thought it was a cool gift idea: you send in some spit, pay a fee, and they tell you about your family history and possible health problems.
But now, things have changed.
The company is filing for bankruptcy this week. It was worth $6 billion a few years ago, but now it’s worth much less. Just a year ago, its value was about $13 per share, but this week, it dropped to less than a dollar ($0.64).
The problems started with a break-in last year that affected up to 7 million customers.
The company also struggled to make money because it charged only a one-time fee and offered nothing extra to keep customers coming back.
Why it happened and what’s really scary
The break-in seems to have occurred because people used the same password for 23andMe and other websites. If a hacker gets your password for one site, they can access your other accounts. Hackers count on people being lazy with their passwords—using the same ones everywhere and not changing them after a break-in.
After the break-in, hackers said they would sell sensitive information on the dark web, including family history and health information. This is dangerous because, for example, terrorist groups could use it to target people based on their ancestry.
Sharing your passwords is a big deal.
But here’s what’s really scary: 23andMe not only lost customer data but also controls their customers’ DNA. If you read the fine print, they have deals with medical companies to share that DNA for research. One big partner is GlaxoSmithKline.
It used to be bad if a company sold your phone number, and then they started selling your internet browsing history. Now, a company is selling your genetic information. What will they use it for? It sounds like a movie plot – complete identity theft, not just credit card numbers, but your DNA. It might seem crazy, but we’ll see what happens.
What you can do
If you’re a 23andMe customer, you should delete your account and ask them to destroy your DNA sample if the law allows it.
To stay safe online:
Don’t post your birthday or hometown online.
Don’t click on emails from people you don’t know.
Don’t answer texts from strangers.
Use different, strong passwords for every website.
Even the military warned soldiers not to use these DNA services because the information could be misused.
So, if someone asks you to spit in a tube to learn about your family history, just say no.
