The FBI said typically travelers attempting to set up a hotel room Internet connection were presented with a pop-up window notifying the user to update a widely used software product. If the user clicked to accept and install the 
update, malicious software was installed on the laptop. The pop-up window appeared to be offering a routine update to a legitimate software product for which updates are frequently available.
The FBI today warned travelers there has been an uptick in malicious software infecting laptops and other devices linked to hotel Internet connections.
The FBI wasn’t specific about any particular hotel chain, nor the software involved but stated: “Recent analysis from the FBI and other government agencies demonstrates that malicious actors are targeting travelers abroad through pop-up windows while they are establishing an Internet connection in their hotel rooms.
The FBI also recommends that travelers perform software updates on laptops immediately before traveling, and that they download software updates directly from the software vendor’s website if updates are necessary while abroad.”
