India's popular hotel and homestay chain OYO is facing flak for leaving the personal data of its customers exposed.
The service, which is owned by 25-year-old Ritesh Agarwal, was caught exposing confidential information, including the phone numbers of customers as well as their booking details, at a partner hotel.
However, it says that the issue has now been resolved.
Here's more on the matter.

During a recent OYO stay, cybersecurity expert Jay Sharma spotted an issue with the Wi-Fi login system of his hotel.
He noted that the vulnerability can be exploited with a brute force attack to extract data starting from customer Booking IDs and phone numbers to the date and location of booking.
"All the historical data dating back to few months was accessible," he claimed.

Issue
What was the issue that exposed this data?
-
In the hotel, Sharma found that OYO's Wi-Fi login required customers to enter their Booking ID, number.
On digging into it, he discovered that "the http & ssh ports were open with no rate limit for the IP which was hosting this. Captcha was a 5 digit number generated by math.random()."
This allowed him "to brute force the login credentials while executing the captcha".

"The booking IDs and phone numbers related to these IDs with timestamps were stored naked and all of it could be downloaded," Sharma said, adding that "you could compute on the data to extract OYO couples living in a room, phone numbers, social information etc."

Fix
OYO fixed the issue after Sharma's report

When Sharma reported the issue to OYO, the company issued a fix for the vulnerability and paid him a reward of Rs. 25,000.
A spokesperson told ET that the flaw was restricted to a single property and was fixed immediately after disclosure.
"Any vulnerability, no matter how limited-time or small is taken very seriously and looked into," the representative added.

Even though the issue has been fixed, many details remain unclear, including how many customers' information was leaked and if anyone else (before Sharma) had access to this data.
To note, the vulnerability, which risked location and other details of guests, has already triggered a wave of criticism against the company, which has been touting itself as a 'couple-friendly' place to stay.
