An anonymous reader quotes a report from 404 Media: The code that runs Redbox DVD rental machines has been dumped online, and, in the wake of the company's bankruptcy, a community of tinkerers and reverse engineers are probing the operating system to learn how it works. Naturally, one of the first things people did was make one of the machines run Doom. As has been detailed in several great articles elsewhere, the end of Redbox has been a clusterfuck, with pharmacies, grocery stores, and other retailers stuck with very large, heavy, abandoned DVD rental kiosks. To many people's surprise, many of the kiosks remain operational even with the bankruptcy of Redbox's parent company, which has led some people to "liberate" DVDs from the abandoned kiosks. Reddit is full of posts by people who say they have taken dozens of DVDs from kiosks all over the country. Free DVDs is one thing. But in recent days, people have realized that they can, in some cases, get free Redbox kiosks. In an August filing, Walgreens told the bankruptcy court that it has 5,400 abandoned kiosks at its stores, and that it is spending $184,000 a month keeping them powered. "Walgreens should not be required to continue to 'store' and power Redbox kiosks across the country without any form of payment," the company wrote. And so tinkerers and reverse engineers have begun asking stores whether they can take the devices off their hands. There are also posts on Reddit by contractors who are selling them, and I was able to find various Redbox DVD kiosks being advertised for sale on Facebook Marketplace. (There are far more listings on Facebook Marketplace from people who have obtained hundreds or thousands of Redbox DVDs and are now selling them.)
Recently the operating system for Redbox kiosks was dumped online, and this community is now probing it to see how it works. In a thread on Mastodon, reverse engineer Foone Turing has been posting some of her findings, which include the fact that Redbox machines contain a file that has "a complete list of titles ever rented, and the email addresses of the people who rented them, and where and when." She also found that the first six and last four digits of credit card information was logged. She said that the records on the particular unit that she was looking at contained 2,471 different transactions and had records on it dating back to 2015. Other reverse engineers have found that Redbox kiosks contained information about the physical locations of every other kiosk. The server that they communicated with is currently offline (because the company is bankrupt). But people have also been putting together information about what different error codes in the software mean (for example, the error code "0020BDT" would happen when an obstruction was detected in the machine). They have also found and dumped service manuals for different parts of the device and have found a few login passwords (one password is "US#1Choice4movierentals"). [...] There has also been discussion about how the machines could be modified to talk to a new server, or whether the operating system could be put on a DIY Redbox device. Another person installed Minecraft on their Redbox. It is still very early days, but, with the bankruptcy of Redbox's parent company, ironically these devices are being given new life.
