Tomi Tuominen and Timo Hirvonen, both researchers at cybersecurity firm F-Secure, have discovered a security flaw in the most popular manufacturer line of digital hotel locks.

Why it matters: Though they've worked with the manufacturers on a patch that has already been released, it is likely that not all the doors have been patched yet as 40 thousand hotels use the locks. The duo noted to Axios that manufacturer Assa Abloy's locks were very secure and the company was attentive to the problem. This is a prime example of a company doing everything right and still having vulnerabilities because no product is 100% secure.
