You’re sitting at dinner, your phone buzzes, and you see a message from an unknown number. It just says "Hello" or maybe "Hi, is this Mark?" You aren't Mark. Your first instinct is probably to be polite and text back saying they have the wrong person.
Stop right there.
That simple, seemingly innocent interaction is the cornerstone of a massive global fraud industry. While it feels like a glitch in the digital matrix or a lonely stranger making a mistake, random texts saying hello are almost never accidental. They are the "hook" in a sophisticated psychological game designed to drain your bank account. Security experts call this "Pig Butchering," or Sha Zhu Pan, a term that originated in China to describe how victims are "fattened up" with friendship before being financially slaughtered.
The Psychology Behind the "Wrong Number" Hello
Scammers don't just guess numbers at random anymore. They buy huge databases of leaked phone numbers from dark web forums. When you get one of these random texts saying hello, the sender is testing the waters. They want to see if the line is active.
Think about it.
If you reply, you’ve just confirmed three things: your number is real, you actually read your texts, and you’re a helpful, polite human being. That’s a goldmine for a social engineer. They use our natural tendency toward "reciprocal altruism." When someone is nice to us, or seems to need a small bit of help—like finding out they have the wrong number—we feel a social pull to respond.
Honestly, it’s a brilliant, if evil, tactic. It bypasses the "stranger danger" alarms that go off when we see a weird link or a suspicious attachment. It's just a greeting. What could be the harm?
How a Simple Greeting Turns Into a Scam
The evolution of these messages is fascinating in a dark way. After you tell them they have the wrong number, the scammer usually responds with something like, "Oh, I'm so sorry! You seem like such a kind person. Since we met by chance, maybe we can be friends?"
It sounds ridiculous when you read it here.
But in the moment, if you're bored or feeling a bit isolated, that dopamine hit of a new social connection can be powerful. They aren't asking for money—not yet. They might spend weeks, or even months, building a rapport. They'll send photos of their "dinner" (usually stolen from Instagram influencers) or talk about their "wealthy uncle" who teaches them about cryptocurrency.

The Industry of Human Trafficking Behind the Text
Here is the part that most people get wrong: the person sending you that "Hello" might be a victim themselves. Investigations by organizations like ProPublica and Interpol have revealed massive "scam compounds" in Southeast Asia, particularly in Cambodia and Myanmar.
Thousands of people are lured there with promises of high-paying tech jobs, only to have their passports seized. They are forced to work 16-hour shifts sending out thousands of random texts saying hello. If they don't meet their quotas, they face physical abuse. This isn't just a guy in a basement; it's a multi-billion dollar organized crime operation backed by human trafficking.
When you engage with these texts, you aren't just risking your own money. You're inadvertently participating in a cycle of digital slavery.
The Technical Red Flags You're Missing
Next time one of these pops up, look closer at the details. Often, the number will be from a VoIP (Voice over IP) service like Google Voice or a temporary burner app. These are hard to trace and easy to discard once the scam is complete.
Also, notice the timing. Many of these "Hi" messages arrive during off-hours for your local time zone because the person on the other end is literally on the other side of the planet.
- The Profile Picture: Usually a generic, attractive person.
- The Grammar: It's often "good but weird," using formal phrasing that doesn't quite match casual texting culture.
- The Pivot: They will almost always try to move the conversation to WhatsApp or Telegram. Why? Because those platforms have end-to-end encryption, making it much harder for law enforcement to track the scam.
Why You Shouldn't Just "Troll" the Scammer
We’ve all seen the funny screenshots. Someone gets a scam text and replies with a meme or a sarcastic joke. It feels satisfying to "win" the interaction.
Don't do it.
Even a joke reply confirms your number is "live." Once you're tagged as a "responder" in their database, your number gets sold to other scam groups as a "high-value target." You’ll notice a massive spike in spam calls and texts within days of "trolling" a scammer.
Basically, the only winning move is not to play.
Protecting Yourself and Your Data
If you’re tired of the constant "Hello" pings, there are actual steps you can take. Most people just swipe the notification away, but that doesn't solve the problem.

- Enable "Silence Unknown Senders" on iPhone: Go to Settings > Messages > Unknown & Spam. This filters these texts into a separate list so you never even see the notification.
- Use "Verified SMS" on Android: Google’s Messages app has built-in spam protection that catches many of these before they hit your inbox.
- Report as Junk: Don't just delete the thread. Use the "Report Junk" feature built into your OS. This feeds the data back to the carriers so they can block the originating numbers at the network level.
- The 24-Hour Rule: If you get a text from an unknown person and you think it might be real, wait 24 hours. A real person who made a mistake usually won't follow up with a philosophical life story.
Practical Steps to Secure Your Phone Right Now
If you have already replied to one of these random texts saying hello, don't panic. You haven't been "hacked" just by sending a text. However, you should heighten your defenses.
Check your privacy settings on social media. Scammers take your phone number and search for it on Facebook or LinkedIn to find your real name, job, and family members. If your profiles are public, they can use that info to make their "friendship" feel more authentic. Lock those profiles down to "Friends Only."
Also, set up a secondary "junk" number using an app like Burner or Google Voice for when you have to provide a phone number to websites or stores. Keeping your primary number "clean" is the best way to avoid the hello-text plague in the first place.
The digital world has made it incredibly easy for people to reach out and touch us. Usually, that’s a good thing. But in the era of automated "Hello" scams, skepticism is your best friend. If you don't know the sender, you don't owe them a reply. Not even to be polite.
Ignore the text. Block the number. Move on with your day.
Immediate Action Items:
- Block and Delete: Do not reply to any unknown greeting, even to say "wrong number."
- Audit Your Privacy: Ensure your phone number isn't publicly searchable on social media platforms.
- Update Software: Keep your phone's OS updated to benefit from the latest carrier-level spam filtering algorithms.
