Total Defense Security Tip of the Day
06.22.25
Your digital instincts: when in doubt, delete it!
Our online lives are full of links. We click them in emails, tap them in texts, scroll past them in social media feeds, and see them in online ads. They're how we navigate the internet, get information, and connect with the world. But here's the crucial warning: these very links are also cybercriminals' favorite tools for trying to steal your personal information, infect your devices, or trick you into giving away your money.
Think of suspicious links like a shady person offering you a "free gift" down a dark alley. Your gut instinct screams, "Don't go there!" The same applies online. If something looks even a tiny bit off, your best defense is often the simplest: delete it immediately! It might feel like overkill, especially if it looks like it's from someone you know, but a moment of caution can save you from a huge headache later.
The Link Labyrinth: How Cybercriminals Lure You In
Cybercriminals use links in various sneaky ways:
- Phishing Emails: These are designed to look like they're from legitimate companies (your bank, Amazon, Netflix, a government agency) and trick you into clicking a link that leads to a fake login page. Once you enter your credentials, they've got them!
- Smishing Texts (SMS Phishing): Similar to email phishing, but via text message. You might get a text about a "delivery issue" or a "security alert" with a malicious link.
- Social Media Scams: Links to fake contests, "too good to be true" offers, or shocking news stories that lead to malware downloads or phishing sites.
- Malicious Ads: Even legitimate websites can sometimes host ads that lead to dangerous sites if you click on them.
- Spoofed Websites: The link might take you to a website that looks identical to a real one, but the URL in the address bar is slightly different.
Your Golden Rule: If It Looks Suspicious, Delete It!
This simple rule is your shield against a huge array of online threats. Here's how to apply it:
- From Strangers? IMMEDIATELY DELETE! If an email, text, or social media message is from someone you don't know and contains a link, do not even think about clicking it. Delete it. Block the sender. End of story.
- From Someone You Know, But It Looks Weird? Still Suspect! This is where it gets tricky. Your friend's Facebook account might have been hacked, or a scammer might be impersonating a colleague's email address.
- Odd Wording/Grammar: Does the message sound unlike your friend? Are there strange typos or grammatical errors?
- Unexpected Request: Is it asking you to click a link or do something unusual that's out of character for them?
- Generic Greeting: Does it say "Hi friend" instead of using your name?
- If in doubt, throw it out. Even if it seems to be from a known source, if something feels off, delete it. Then, contact the person through a different method (like a phone call or a separate, new email) to ask if they sent it.
- Hover Before You Click (on a computer): This is your best detective tool! Before clicking a link, hover your mouse cursor over it. A small box will usually appear showing the actual destination URL. If it doesn't match where you expect to go (e.g., it says "https://www.google.com/search?q=paypal.scam.com" instead of "paypal.com"), DO NOT CLICK!
- Don't Trust Shortened Links (from unknown sources): Services like bit.ly can hide the true destination of a link. Be very wary of shortened links from sources you don't trust.
- Use Email Scanning Software: Many reputable antivirus and internet security suites (like Total Defense!) include email scanning features that help filter out suspicious emails and protect you from malicious links and attachments. Make sure your security software is always up-to-date and running.
Developing a healthy skepticism about links is a vital cybersecurity habit. A moment of caution and the willingness to hit that delete button can save you from a world of trouble. Trust your gut – if something looks suspicious, it probably is.
