Hackers Steal Microsoft 365 Accounts via Hotel Wi-Fi

DNS Manipulation: A Growing Threat

Hackers are targeting hotel and conference center Wi-Fi users, altering DNS settings to redirect them to fake Microsoft 365 login pages. The campaign started in June and affects various sectors, including finance. Organizations and individuals are being compromised.

The attackers manipulate DNS settings on devices connected to public Wi-Fi networks. This allows them to redirect users to phishing sites when they attempt to access Microsoft 365. The fake login pages are likely designed to capture login credentials.

Can Public Wi-Fi Ever Be Safe?

The method used by the hackers exploits the trust users have in public Wi-Fi networks. When a device connects to a compromised network, the DNS settings are altered. This can happen without the user's knowledge, making it difficult to detect.

The campaign's scope and the number of affected organizations are not yet fully understood. However, the threat is significant, given the widespread use of Microsoft 365.

Users often rely on public Wi-Fi for convenience, unaware of the risks. To mitigate these risks, users can take precautions such as using a VPN. This encrypts their internet traffic, making it harder for hackers to intercept their data.
