Scammers don’t discriminate.
Anyone can be a target.

You don’t have to be rich or run a company to become a victim. One SMS, one click or one phone call “from your grandchild” is enough. In this guide you will learn how the most common scams work, how to spot them and how to protect yourself, your family and your business.

4 scams that target everyday households

Each one looks innocent. Each relies on haste and trust. See how they work and what protects you against them.

“Pay PLN 1.99 extra for your parcel”

Your parcel is waiting. Pay PLN 1.99: doplata-paczka24.top

What happens
The page looks like a courier or post office. You enter your card details – and the scammer withdraws far more than PLN 1.99 from your account. [8]
How to defend yourself
Check parcel status only in the courier’s app or by typing the address yourself. A padlock icon next to the address does not mean the site is honest.
LKH Secure
Blocks sites from the CERT Polska scam list, updated every 5 minutes. The fake page simply won’t open.

“Can I borrow a BLIK code? I’m at the checkout”

Hey, my card isn’t working, can you send me a BLIK code for PLN 500? I’ll pay you back tonight

What happens
The message comes from your friend’s real profile – because someone took over their account. You give the code and the money disappears in seconds.
How to defend yourself
Call that person on a number you know. In your banking app, always read the amount and recipient before approving BLIK.
LKH Secure
No filter can help here – the message arrives via a regular messenger. One rule protects you: always verify money requests by voice call.

“Mum, I had an accident, I need money”

You hear your daughter’s crying voice on the phone. It sounds just like her.

What happens
Artificial intelligence can clone a voice from just a few seconds of online audio. The FBI warns against such scams. [2]
How to defend yourself
Hang up and call back yourself. Agree on a family codeword known only to you – the scammer won’t know it.
LKH Secure
If the caller tells you to open a “quick payment” site and it is on the scam list, LKH Secure will block it.

“Earn PLN 3,000 a week, like a famous actor”

An ad featuring a celebrity’s photo, followed by a call from an “investment advisor”.

What happens
The fake platform shows “profits” so you deposit more and more. The advisor asks you to install remote desktop software and “helps” make the transfer. [9]
How to defend yourself
Never install software at a stranger’s request. A familiar face in an ad proves nothing.
LKH Secure
Blocks fake investment platforms that CERT Polska has already identified and added to its warning list.

Children online: you can’t look over their shoulder all the time

The internet is for learning, games and staying in touch with peers. Yet one click is enough for a child to stumble upon adult content, a fake in-game “prize” or someone asking for photos or passwords.

What technology can do

  • Block adult websites, gambling and dangerous content across your entire home Wi-Fi
  • Set internet usage hours, e.g. no access at night
  • Turn off internet only on your child’s phone – the TV keeps working

Site blocking and a whole-home schedule are provided by LKH Secure Rodzina, while per-device hours and pausing are provided by LKH Secure Router.

What technology cannot replace

  • Conversation: “if anyone asks for a photo, password or secret – come to me”
  • Settings on the phone itself: purchases, contacts, apps
  • Parental attention – away from home on mobile data, Private DNS must be enabled once on an Android phone (Rodzina, Max and Router plans)

Helpful tips are provided by the Central Office of Information Technology (COI). [10]

You can’t retake photos from your child’s first birthday

Photos, documents and messages often live on a single phone or a single account. One theft, hardware failure or hijacked account and everything disappears.

  1. Make a backup in a second, independent location and check periodically that files can be restored. Cloud sync alone is not a backup – a deleted file disappears everywhere. [11]
  2. Secure your e-mail. It is the key to all other accounts: passwords are reset through it. Set a unique password and two-factor authentication.
  3. Keep your phone, computer and router updated. Updates patch vulnerabilities that attackers exploit.

“We are too small for anyone to attack us” – a very costly myth

Criminals don’t pick companies by name. Automated bots scan the internet for poorly secured devices, and phishing e-mails hit thousands of companies at once. It only takes one person clicking.

Bank account number change

“Hello, we changed banks, please transfer to the new account.” The e-mail looks like it is from a regular supplier. The money goes to a scammer. [5]

Defence: confirm every bank account change by phone on a known number.

Fake login page

“A document was shared with you.” An employee enters their e-mail password on a fake page – and the attacker reads company correspondence.

Defence: LKH Secure blocks known phishing sites, and two-factor authentication stops the rest.

Encrypted data

Ransomware locks software and documents, and attackers threaten to leak data. Paying the ransom guarantees nothing. [6]

Defence: blocking attacker servers, firewall and off-site backups.

How much does one day without computers cost your company?

Labour time alone is 2 880 PLN

That is only your team’s time – excluding recovery, lost orders, contractual penalties and client trust. Illustrative calculation, not a forecast for your business.

Artificial intelligence works for scammers too

Before

Scams were easy to spot by typos: “Dear customer, your accont has been locked”.

Today

AI writes flawless “bank” e-mails, clones voices and faces, and spins up a fake shop in minutes. [2]

The UK NCSC estimates that by 2027 AI will also accelerate intrusions: attackers use automated AI agents to find flaws faster and exploit outdated devices. [3] Jakub Pachocki from OpenAI also writes about the need to strengthen defences. [4]

The conclusion is simple: in the era of AI agents, nobody can stay 100% alert at all times. Fatigue, haste and a convincing story affect everyone. That is why LKH introduced LKH Secure – network-side protection that stops known attacks and scams before they cause harm.

Good protection has several layers – like locks on a door

No single program can stop everything. That is why safeguards complement each other: when one fails, the next steps in. [6] [7]

  1. 1
    Network: LKH Secure

    Blocks known scam, malware and attacker servers on all devices at home or in the office – without installing anything.

  2. 2
    Devices

    Up-to-date OS, built-in antivirus (e.g. Windows Defender) and the free extension LKH Secure in your browser, which also protects you away from home.

  3. 3
    Accounts

    Unique passwords and two-factor authentication – especially for e-mail and banking.

  4. 4
    Backups

    When everything else fails, you recover your photos and documents. For businesses: LKH Secure Backup.

  5. 5
    You and your loved ones

    The “verify money requests by voice call” rule and never installing software asked for by strangers.

What does each layer do in practice?

Threat LKH Secure DNS (Start / Rodzina / Max / Router) LKH Secure Firewall Pro / Box Antivirus & LKH Opieka IT
Fake link (SMS, e-mail, messenger) Blocks opening a known fake domain – at home and on LTE/5G (Android). Blocks the DNS domain as well as full URLs and network intrusion attempts (IPS). Protects at the browser or system level on the specific computer.
Infected e-mail attachment or downloaded file Does not scan file contents, but blocks the malware from connecting to an attacker server (C2). Scans transferred files in network traffic (with HTTPS inspection on Windows; excluding password-protected archives). Stops a malicious file on disk when saved or opened; in LKH Opieka IT we monitor its operation and updates.
Bypassing blocks via VPN, proxy and Tor Blocks over 116,000 known VPN/proxy/Tor domains; your company’s own VPN usually works, and a cloud VPN can be added to the Max allowlist or bypassed by schedule in Rodzina. Application control also blocks VPN apps connecting directly by IP address (with an optional exception for corporate VPN). Not intended for filtering traffic or VPN tunnels.

Four habits that complement your protection.

LKH Secure stops recognised threats on your connection. These simple rules protect you away from home too.

  1. Use different passwords and enable multi-factor authentication wherever available.
  2. Keep your phone, computer and router updated. Use up-to-date device protection.
  3. Check the website address. An urgent request for a payment, password or BLIK code needs additional verification.
  4. Make independent backups of important data and check that you can restore them.

You can report a suspicious website or message to CERT Polska. Forward suspicious text messages to 8080. Report a threat to CERT Polska

Enable protection before you need it

Money takes years to save, family photos cannot be recreated and client trust takes time to build. LKH Secure works on your connection from PLN 6.90/month – for home, family and business.
