The notorious ShinyHunters extortion group has published data allegedly stolen from the telecoms services provider Charter Communications. ShinyHunters is known for engaging in voice phishing attacks to gain access to victim organizations’ networks and rapidly exfiltrate data that it then threatens to leak online unless a ransom is paid. The group lists its victims on a Tor-based leak site, and the data it claims to have been stolen from Charter was made available for download on that portal on Thursday, which suggests that the company did not pay a ransom to prevent its publication. According to ShinyHunters’ post, the stolen…

When people ask me for a streaming device recommendation, I almost always suggest a Roku (because not everyone needs a streaming device with 256 CPU cores). This is because Roku devices are reliable, easy to use, not expensive, and most importantly, they work with every streaming service you could ever want. And there are even multiple uses for old Roku devices. But what happens when your Roku is not working properly, and you need to troubleshoot your connection? Well, it turns out that Roku has built-in secret menus, only accessible by tapping a combination of keys on your remote, that…
