Spanish police arrested a hacker who allegedly manipulated a hotel booking website, allowing him to pay one cent for luxury hotel stays. He also raided the mini-bars and didn't settle some of those tabs, police say. "This cyberattack was specifically designed to alter the payment validation system, and this is the first time we have detected a crime using this method," Spain's National Police told media outlets . The man, a 20-year-old Spanish national, was arrested while staying at a Madrid hotel with a four-night reservation that carried a €4,000 ($4,716) price tag – unless you hacked the payment system, as this fraudster did. According to the cops, he stayed at this hotel several times, costing the business more than €20,000 ($23,608) in losses. Police began investigating the suspect earlier this month after an unnamed online booking website reported suspicious activity. The transactions appeared normal, indicating the man paid the full amount – at first.

Adding insult to injury, police said that the man also consumed mini-bar bottles and sometimes left those bills unpaid, too. While he may be facing a free stay at a mini-bar free, unluxurious facility for his alleged crimes, we have an idea for his next big vacay, post-prison: an inflatable moon hotel. The definitely-going-to-happen hotel , slated to open in 2032, requires a deposit of either $250,000 or $1 million. No word on whether GRU Space, the hotel's operators, have received any one cent deposits – yet. ® More about Cybercrime Security Spain More like these More about More about Cybercrime Security Spain More like these TIP US OFF Send us news
