1. Researchers have discovered the presence of a consumer-grade spyware application in the check-in systems of three major hotel chains in the United States. The spyware, known as "StrandHogg," was found to be capable of recording audio, capturing screenshots, and stealing personal information from hotel guests' devices when they connected to the hotel's Wi-Fi network.

2. The discovery of this spyware raises serious concerns about the security and privacy of hotel guests, as the collected data could potentially be used for malicious purposes such as identity theft or targeted attacks. The researchers have notified the affected hotel chains, but it is unclear if the issue has been fully resolved or if the spyware has been removed from the affected systems.

3. The use of consumer-grade spyware in hotel check-in systems highlights the need for improved security measures and better oversight of the technology used in the hospitality industry. Experts recommend that travelers be cautious when using hotel Wi-Fi networks and consider using a virtual private network (VPN) to protect their online activities and sensitive information.
