Microsoft and security researchers warn that Russian-linked hackers are compromising hotel Wi‑Fi networks and using them to attack travelers. According to the reports, attackers infiltrate hospitality internet infrastructure and then leverage that access to intercept or capture sensitive information such as passwords. The activity is also described as enabling malware distribution and surveillance of victims who connect to the compromised networks. One method highlighted is the use of deceptive sign-in pages that can appear legitimate to users, tricking travelers into entering credentials that the attackers can collect. The reports emphasize that many affected travelers may not notice anything unusual during the process, because the networks are trusted by users and may look normal. Microsoft’s warning is presented as a cybersecurity alert based on observations and analysis of ongoing threats, with researchers advising organizations and travelers to take precautions when using public or hotel Wi‑Fi, particularly for work-related logins. The sources collectively describe a pattern in which attackers use hijacked hotel connectivity as an access point to broader targeting of travelers.
