Quickly checking emails on the train, checking the Bitcoin price at the gate, checking the last transaction in the hotel – for many people, public WiFi is a natural part of traveling and almost acts like a socket for digital life. This is exactly the routine attackers rely on when they set up fake hotspots that look inconspicuous and target access data and crypto assets.
• Evil Twin attacks use fake Wi-Fi access points
• Attack locations include airports, hotels, train stations, cafes and conference centers
• Phishing and social engineering lead to losses
What are Evil Twin Attacks?
The term Evil Twin describes an “evil twin” of a WLAN: an access point that looks confusingly similar to the original in name and appearance, but is completely under the control of the attackers. Technically, a separate access point is set up with the same or only slightly modified SSID, which means that devices that automatically connect to known networks often end up in the wrong network without conscious intervention. Security analyzes show that attackers can use this access not only to read the data traffic, but also to specifically redirect requests, for example to phishing pages or manipulated portals that are very similar to the login masks of exchanges or wallet providers.

How wallet holdings are actually stolen
Cryptocurrencies don’t disappear just by connecting a device to someone else’s WiFi; The actual damage occurs in the interaction of manipulated data traffic and phishing mechanisms, as shown in the post by an X user who acts as an ethical hacker and demonstrates such an attack to clarify the situation.
Most people assume that if their Wi-Fi uses WPA2 with a strong password, they’re safe. But little do they know that attackers don’t always need to crack the password to get what they want. One powerful method hackers use is the Evil Twin attack where they clone a legitimate Wi-Fi… https://t.co/6gVg9xiusb pic.twitter.com/DDsKdstT9t

Controlled access allows attackers to deliver deceptively genuine login pages for well-known platforms or replicate wallet interfaces that appear to request routine security checks, logins or restores, while in reality they are harvesting credentials and keys. According to Cointelegraph, 23pds, Chief Information Security Officer at SlowMist, describes that in such scenarios, users are drawn into a sequence of confirmation steps via fake update notices, alleged help programs or supposedly urgent warning messages, which often end with the disclosure of sensitive information that reputable providers would never ask for.
Practical protection measures for traveling crypto users
Cointelegraph also recommends relocating particularly security-critical processes to times and locations with a reliable connection and only carrying out absolutely necessary actions while on the move in order to limit the attack surface. This includes, for example, not setting up new wallets when traveling, not resetting passwords and not moving large amounts from insecure networks, as the potential damage is particularly high in the event of an error. The crypto exchange Binance also emphasizes that the seed phrase should only be kept offline and should under no circumstances be entered into websites, apps or support interfaces.
When accessing crypto services via the browser, Cointelegraph recommends using fixed bookmarks for central services and entering domains manually if you are unsure, as deceptively real phishing links regularly appear in both search engines and advertisements, which at first glance look like official pages.
