Last year, a vigilante hacker broke into the servers of a company that sells spyware to everyday consumers and wiped their servers, deleting photos captured from monitored devices. A year later, the hacker has done it again. Motherboard: Thursday, the hacker said he started wiping some cloud servers that belong to Retina-X Studios, a Florida-based company that sells spyware products targeted at parents and employers, but that are also used by people to spy on their partners without their consent. Retina-X was one of two companies that were breached last year in a series of hacks that exposed the fact that many otherwise ordinary people surreptitiously install spyware on their partners' and children's phones in order to spy on them. This software has been called "stalkerware" by some.
