The words scammers hope you don’t know.

Also called Hacked account, ATO

In real life: A scammer logs in to your social media, changes the password, and messages your friends asking for money.

Why it matters: Hijacked accounts are used to scam your friends. Turn on two factor so a password alone isn’t enough.

Also called Autonomous AI

In real life: Given one goal, ‘plan my holiday’, an agentic AI compares hotels, books one and emails you the plan.

Why it matters: The more it does alone, the more a mistake or trick can cost. Make it ask before it pays or sends.

Also called Artificial intelligence

In real life: You ask an AI app to write a birthday poem for your sister, and it does it in seconds.

Why it matters: Scammers use AI for perfect messages, fake voices and fake faces, so bad spelling is no longer a giveaway.

Also called Agent

In real life: You ask an AI agent to find a cheap flight, and it searches, picks a seat and pays with your saved card.

Why it matters: It acts with your accounts and money, so a trick that fools it can cost you. Make it check with you first.

Also called Agentic browser, AI web browser

In real life: You ask your AI browser to buy concert tickets, and it opens the site, picks seats and types in your card.

Why it matters: A trick hidden on a web page can steer it. Keep it away from banking and check before it pays.

Also called Hallucination

In real life: You ask an AI chatbot for your bank’s phone number and it confidently gives you one that doesn’t exist.

Why it matters: AI can sound sure and still be wrong. Check important facts, numbers and links with a trusted source.

Also called Jailbreaking

In real life: Scammers jailbreak a chatbot with a made up story so it writes the convincing scam emails it would normally refuse.

Why it matters: Safety rules can be talked around, so scammers still get help from AI. Polished writing proves nothing.

In real life: A checking tool finds a hidden AI watermark in a viral photo, showing it was made by an image generator.

Why it matters: No watermark doesn’t mean it’s real. Many AI tools add none, and some marks can be removed.

Also called Antivirus software, Security software

In real life: Your antivirus warns that a file you just downloaded is harmful and moves it somewhere safe.

Why it matters: It catches many known threats, but it can’t stop you being tricked. Keep it on and updated.

Also called Authenticator, 2FA app

In real life: To sign in to your email, you open your authenticator app and type the six digit code it shows.

Why it matters: Codes made on your own phone are safer than texted ones, which a SIM swap can steal.

Why it matters: With a recent backup, ransomware, a broken phone or a lost laptop can’t take your memories.

Also called Bot account

In real life: Hundreds of bot accounts flood a post with the same glowing comments about a crypto app.

Why it matters: Bots can fake crowds, likes and even friendships. Lots of praise from brand new accounts is a warning sign.

Also called Zombie network, Bot network

Why it matters: Your own gadgets can be roped in. Change default passwords and keep routers and cameras updated.

Also called Add on, Plugin

In real life: A hacker’s computer tries billions of guesses against a stolen password file until it cracks yours.

Why it matters: Short passwords fall in seconds, while five or more random words can take a computer years to crack.

Also called BEC, CEO fraud, Email account compromise

In real life: Scammers break into a builder’s email and send a real customer a final bill with new bank details.

Why it matters: It’s one of the costliest scams. Always confirm new payment details by phone on a number you trust.

Also called I’m not a robot check

In real life: A fake ‘I’m not a robot’ check tells you to press some keys and paste in a command to prove you’re human.

Why it matters: Real checks never ask you to press special keys or paste anything. If one does, it’s a trick to install malware.

Also called Skimming, ATM skimming

In real life: A thin fake card slot on a fuel pump copies the card of everyone who fills up that day.

Why it matters: Cover the keypad when you type your PIN, and tap to pay where you can, as tapping is harder to skim.

Also called Card dispute, Disputed transaction

In real life: Your online order never arrives and the shop goes quiet, so you ask your bank for a chargeback.

Why it matters: Paying by card can get your money back after some scams. Bank transfers and gift cards usually can’t.

Also called Chat bot, AI chatbot, AI assistant

In real life: The chat window on your bank’s website is a chatbot that answers simple questions any time of day.

Why it matters: Scammers run fake chatbots too. Only chat on the real website or app, and never share passwords.

Also called Virus

In real life: A virus on a friend’s USB stick copies itself onto every computer it gets plugged into.

Why it matters: Viruses can delete files or open a door for hackers. Keep your antivirus on and your device updated.

Also called Browser cookies

In real life: A pop up asks whether you accept cookies before you can read the rest of a news website.

Why it matters: Cookies can track you across sites, and stolen login cookies can let hackers into your accounts.

In real life: Hackers take emails and passwords from an old data breach and try them on banking and shopping sites.

Why it matters: It only works if you reuse passwords. A different password for every account stops it cold.

Also called Bitcoin ATM, Crypto kiosk

Why it matters: No real bank, government or police officer will ever ask you to pay through a crypto ATM.

Also called Crypto

In real life: A ‘friend’ online says you can make easy money by buying cryptocurrency through an app they use.

Why it matters: Crypto payments are hard to trace and almost never come back, which is why scammers ask for it.

Also called Darknet

In real life: After a data breach, millions of customers’ emails and passwords turn up for sale on the dark web.

Why it matters: If your details are leaked there, scammers can use them. Change that password and turn on two factor.

Also called Data leak

In real life: A big online store emails to say hackers stole customer names, emails and passwords last week.

Why it matters: Scammers use breached details to sound real. Change that password and watch for scam messages.

Also called Information broker

Why it matters: Scammers can buy these lists to target people. Some brokers let you ask them to remove your details.

Also called Deep fake

In real life: A video of a famous business leader ‘recommending’ a crypto scheme turns out to be a deepfake.

Why it matters: Deepfakes are cheap and convincing now. Don’t trust a face or voice alone when money is involved.

Also called Domain

In real life: A link reads paypal.com.secure-login.net, but its real domain name is secure-login.net, so it’s not PayPal.

Why it matters: Scammers tuck real brand names into fake addresses. Read the part just before the first single slash.

In real life: Because her messages are encrypted, nobody else can read them as they travel to her friend’s phone.

Why it matters: It keeps messages and payments private. A phone with a passcode is encrypted, so thieves can’t read it.

Also called End of life, EOL

In real life: Your old tablet still turns on fine, but it reached end of support and hasn’t had a security update in years.

Why it matters: Old devices can look fine but stay open to hackers. Replace them once the updates stop coming.

Also called Evil twin, Fake hotspot, Rogue hotspot

In real life: At a cafe, you see two networks called ‘Cafe Free Wifi’ and join the one a scammer set up nearby.

Why it matters: Ask staff for the exact network name, avoid banking on public wifi, and use your phone’s data instead.

Also called Safe phrase, Family code word

In real life: A caller sounding just like your grandson says he’s in trouble, but he can’t say the family safe word.

Why it matters: AI can copy a voice from a short clip. A safe word only your family knows beats a perfect fake.

Also called GenAI

In real life: You type ‘a cat surfing at sunset’ and a generative AI tool makes the picture in seconds.

Why it matters: It makes fake photos, voices and messages cheap and easy, so seeing is no longer believing.

Also called Hi Mom scam, Family emergency scam

In real life: A message says ‘Hi Mum, I broke my phone, this is my new number’ and soon asks you to pay a bill.

Why it matters: Call your child on their old number before doing anything. Scammers bet on love making you rush.

Also called Padlock

In real life: A fake bank website shows a padlock and https, because scammers can get those for free too.

Why it matters: It keeps your connection private, but scam sites use it too. Always check the actual web address.

Also called HITL

Why it matters: With you in the loop, a trick or an AI mistake can’t spend your money or send messages without you.

Also called Identity fraud

In real life: Someone uses your name, birthday and address from a data breach to take out a credit card as you.

Why it matters: It can wreck your credit and take months to fix. Guard your ID details like cash.

In real life: A caller says they’re from your bank’s fraud team and asks you to move your money to a ‘safe account’.

Why it matters: Scammers borrow names you trust. Hang up and call back on a number you find yourself.

Also called Investment fraud

Why it matters: Before paying new bank details, call the business on a number you already know to check.

In real life: At the airport, a traveller plugs into a free USB charging station that has been rigged to copy her photos.

Why it matters: It’s rare, but easy to avoid. Use your own charger in a wall socket, or a power bank, instead of public USB ports.

Also called LLM, AI model

In real life: When you chat with an AI assistant, a large language model is working out each word of its reply.

Why it matters: It writes smooth, friendly messages in any language, so scam messages no longer have bad spelling to give them away.

Also called Prize scam, Sweepstakes scam

In real life: An email says you’ve won a foreign lottery you never entered and asks for a ‘processing fee’.

Why it matters: You can’t win a prize you didn’t enter, and real prizes never make you pay to claim them.

Also called Malicious advertising

In real life: A search for your bank shows a sponsored ad at the top that leads to a fake login page.

Why it matters: An ad at the top of a search isn’t proof it’s real. Type the address yourself or use the official app.

Also called Malicious software

In real life: A ‘free’ game you downloaded from a dodgy website quietly starts stealing your saved passwords.

Why it matters: It can empty accounts or lock your files. Only install apps from official app stores.

Also called Push bombing, MFA bombing, Prompt bombing

Why it matters: If you get approval requests you didn’t ask for, someone has your password. Tap no and change it.

In real life: A ‘job’ pays you to receive money into your account and send it on, but it’s stolen money.

Why it matters: You can be in serious trouble even if you were tricked. Never let anyone move money through your account.

Also called Verification code, One time password, OTP

In real life: A caller says they’re from your bank and asks you to read out the code they just texted you.

Why it matters: Never share it with anyone, even ‘your bank’. Anyone asking for it is trying to get into your account.

Also called Fake online shop, Shopping scam

In real life: A website sells designer shoes at 80% off, takes your card payment, then vanishes.

Why it matters: If a deal looks too good to be true, it usually is. Check reviews, and never pay by bank transfer.

Also called Delivery scam, Missed delivery scam

In real life: A text says your parcel couldn’t be delivered and asks you to pay a small redelivery fee using a link.

Why it matters: Most of us are waiting on a parcel, so it works. Track deliveries in the real app or website instead.

In real life: Instead of typing a password, you sign in to your account by looking at your phone.

Why it matters: Passkeys can’t be guessed, reused or typed into a fake website, so they beat phishing.

Also called Password vault, Password keeper

In real life: She remembers one strong main password, and her password manager fills in a different one for every site.

Why it matters: It means a new, strong password for every account, so one data breach can’t unlock the rest.

In real life: An email that looks like it’s from your bank asks you to ‘confirm your account’ using a link.

Why it matters: It’s the most common way scammers get in. Go to the real app or website yourself, not the link.

Also called Romance baiting, Crypto romance scam

In real life: A friendly stranger who texted the ‘wrong number’ chats for weeks, then shows off their crypto app profits.

Why it matters: It can take months and wipe out life savings. A new online friend who talks about investing is a red flag.

Also called Popup, Pop up window

In real life: While you read the news, a pop up flashes ‘Your device has 3 viruses!’ and says to call a number.

Why it matters: Fake warning pop ups are a classic scam. Close the tab and never call a number shown in one.

Also called Ramp and dump, Pump and dump scheme

In real life: A chat group full of ‘investors’ urges everyone to buy a tiny coin now, just before the organisers sell out.

Why it matters: Hot tips in chat groups and on social media are often traps. The people hyping it are the ones selling.

Also called Quick response code

In real life: A sticker on a parking meter has a QR code that takes you to a fake site to pay for parking.

Why it matters: Scammers stick fake codes over real ones. Check the web address before you enter any details.

Also called QR code phishing, QR phishing

Why it matters: Paying doesn’t always get files back. Regular backups mean you can restore them without paying.

Also called Fund recovery scam, Money recovery scam

In real life: After losing savings to a fake investment, you get a call from a ‘lawyer’ who can recover it for a fee.

Why it matters: Scam victims often get targeted again. Real police and banks don’t charge fees to chase lost money.

Also called Remote access fraud, Screen sharing scam

In real life: A ‘bank’ caller asks you to install AnyDesk so they can ‘secure’ your account, then empties it.

Why it matters: Once they’re in, they can see and do everything. Never install an app because a caller tells you to.

Also called Dating scam, Sweetheart scam

In real life: After weeks of sweet messages, a new online partner suddenly needs money for a plane ticket to visit you.

Why it matters: They can chat for months before asking. Never send money to someone you’ve only met online.

Also called Hardware security key, FIDO key

Why it matters: It’s one of the strongest ways to protect an account, because it won’t work on a fake website.

Also called Recovery phrase, Secret recovery phrase

In real life: A ‘wallet support’ chat asks for your 12 word seed phrase to fix an error, then drains your crypto.

Why it matters: Nobody genuine will ever ask for it. Sharing it, even once, hands over every coin in your wallet.

Also called Cookie theft, Cookie hijacking

In real life: Malware copies the login cookies from a gamer’s browser, letting a hacker into his accounts with no password.

Why it matters: It can get past passwords and codes. Don’t install dodgy downloads, and log out of shared computers.

In real life: A ‘bank’ text tells you to download its new app from a link instead of the app store, but it’s malware.

Why it matters: Apps from outside official stores skip safety checks, and scammers often spread fake apps this way.

Why it matters: It hands scammers your texted codes. Ask your phone company to add extra checks to your account.

Also called SMS phishing, Scam text

In real life: A text says your toll payment is overdue and you’ll be fined unless you pay through the link today.

Why it matters: Texts feel personal and urgent, so people tap fast. Never use a link in a text about money or accounts.

Also called Human hacking

In real life: A ‘new IT worker’ calls staff, chats in a friendly way, then asks each of them for their password.

Why it matters: Most scams target people, not computers. Slow down when someone pushes urgency, fear or secrecy.

Also called Update, Security update, Patch

In real life: Your phone asks to install an update overnight that fixes a security flaw hackers are already using.

Why it matters: Updates close the gaps hackers break in through. Turn on automatic updates so you never miss one.

Why it matters: Lots of spam is harmless junk, but some hides scams. Don’t reply or click, just mark it as spam.

Also called Targeted phishing

In real life: An email to a finance worker uses her boss’s name and a real project to ask for an urgent payment.

Why it matters: Scammers research you online first, so a message that knows your details can still be fake.

Also called Caller ID spoofing, Email spoofing

In real life: Your phone shows your bank’s real number, but it’s a scammer who has spoofed it.

Why it matters: A familiar name or number on your screen proves nothing. Check by contacting them yourself.

In real life: A free ‘phone cleaner’ app quietly sends your messages, photos and location to a stranger.

Why it matters: It can steal passwords and private messages. Only install apps from official stores and keep your phone updated.

Also called Job scam, Employment scam

In real life: A message offers paid work ‘liking’ videos, and after a few small payments you’re told to deposit crypto to keep going.

Why it matters: Real jobs never make you pay to get paid. The early small payments are bait for a much bigger loss.

Also called Fake tech support, Tech support fraud

Why it matters: Real tech companies don’t call out of the blue or put phone numbers in warning pop ups.

Also called Trojan horse

In real life: A free video player you download actually hides a Trojan that lets a hacker into your computer.

Also called 2FA, Multifactor authentication, MFA, Two step verification

In real life: After you type your password, your email asks for the six digit code just sent to your phone.

Why it matters: Even if a scammer steals your password, they still can’t get in without that second step.

Also called Lookalike domain, URL hijacking

In real life: You mistype your bank’s web address by one letter and land on a perfect copy run by scammers.

Also called Voice cloning, AI voice clone, Voice deepfake

In real life: A scammer copies a teenager’s voice from her videos, then calls her dad sounding scared and asking for money.

Why it matters: A few seconds of audio is enough. Hang up and call the person back on the number you already have.

Also called Virtual private network

In real life: Before using the hotel wifi, she turns on her VPN so nobody else on the network can see her traffic.

Why it matters: It protects you on public wifi, but it won’t stop scams, fake websites or harmful downloads.

Also called One ring scam, Missed call scam

In real life: You miss a call that rang just once from an unknown international number, and calling back costs a fortune.

Why it matters: Don’t call back numbers you don’t know, especially from other countries. If it matters, they’ll leave a message.

Also called Zero day exploit, Zero day vulnerability

In real life: Hackers use a zero day in a popular web browser for weeks before the company rushes out an urgent fix.

Why it matters: You can’t stop these yourself, but installing updates quickly closes the hole once a fix comes out.
