Security researchers have found flaws in four popular connected storage drives that they say could let hackers access a user’s private and sensitive data. The researchers Paulos Yibelo and Daniel Eshetu said the software running on three of the devices they tested — NetGear Stora, Seagate Home and Medion LifeCloud — can allow an attacker to remotely read, change and delete data without requiring a password. Yibelo, who shared the research with TechCrunch this week and posted the findings Friday, said that many other devices may be at risk. The software, Hipserv, built by tech company Axentra, was largely to blame for three of the four flaws they found.
