"Bitcoin 20 ($BTC20) Airdrop" scam in detail
The site (claimbtc20.pages[.]dev) claims that the first $BTC20 airdrop is currently live. It states that $BTC20 tokens can be put to work by joining a community staking pool to earn additional $BTC20 every 10 minutes. The page encourages participation in an $BTC20 airdrop and instructs users to connect their crypto wallet to check eligibility and claim the airdrop.
A legitimate crypto airdrop is a distribution of free cryptocurrency tokens to users, usually by a blockchain project. However, there are numerous fake giveaways like the one promoted on claimbtc20.pages[.]dev. The purpose of this deceptive site is to trick visitors into connecting their wallets.
After a wallet is connected, the page triggers a crypto drainer, which is a malicious tool designed to move cryptocurrency from the victim's wallet to the cybercriminals' wallet. Once a transaction is confirmed on the blockchain, it is usually irreversible, meaning stolen funds cannot typically be recovered.
For this reason, users should exercise extreme caution when interacting with crypto platforms. They should always confirm that a website or service is legitimate before connecting a wallet or sharing personal information.

How did I open a scam website?
These websites are often spread through phishing emails with harmful links. Scammers also use fake or hacked accounts on Facebook and X (Twitter), as well as compromised WordPress sites and shady ad networks tied to torrenting or illegal streaming sites, or similar platforms.
Additionally, users can be taken to these pages through pop-ups, ads, buttons, or links on unsafe websites, or by interacting with ads generated by adware and notifications from unreliable sources (shady websites).
How to avoid visiting scam pages?
Download software only from trusted sources (official sites or app stores) and avoid pirated programs, key generators, and cracking tools. Keep your system and apps up to date. Avoid suspicious ads, pop-ups, and links, and do not allow notifications from unreliable websites.
Also, treat unexpected emails from unknown senders carefully, especially those with links or attachments. Files and links in such emails (or other messages) should not be opened if they seem questionable. If your computer is already infected with unwanted apps, we recommend running a scan with Combo Cleaner Antivirus for Windows to automatically eliminate them.

How to identify a pop-up scam?
Pop-up windows with various fake messages are a common type of lures cybercriminals use. They collect sensitive personal data, trick Internet users into calling fake tech support numbers, subscribe to useless online services, invest in shady cryptocurrency schemes, etc.
While in the majority of cases these pop-ups don't infect users' devices with malware, they can cause direct monetary loss or could result in identity theft.
Cybercriminals strive to create their rogue pop-up windows to look trustworthy, however, scams typically have the following characteristics:
- Spelling mistakes and non-professional images - Closely inspect the information displayed in a pop-up. Spelling mistakes and unprofessional images could be a sign of a scam.
- Sense of urgency - Countdown timer with a couple of minutes on it, asking you to enter your personal information or subscribe to some online service.
- Statements that you won something - If you haven't participated in a lottery, online competition, etc., and you see a pop-up window stating that you won.
- Computer or mobile device scan - A pop-up window that scans your device and informs of detected issues - is undoubtedly a scam; webpages cannot perform such actions.
- Exclusivity - Pop-up windows stating that only you are given secret access to a financial scheme that can quickly make you rich.
Example of a pop-up scam:

How do pop-up scams work?
Cybercriminals and deceptive marketers usually use various advertising networks, search engine poisoning techniques, and shady websites to generate traffic to their pop-ups. Users land on their online lures after clicking on fake download buttons, using a torrent website, or simply clicking on an Internet search engine result.
Based on users' location and device information, they are presented with a scam pop-up. Lures presented in such pop-ups range from get-rich-quick schemes to fake virus scans.
