Everything is dangerous
Looks like really every program can be harm to your computer these days. I’m reading US CERT reports regularly and yesterday I’ve read this one. Long story short software included with the Energizer DUO USB battery charger contains a backdoor that allows unauthorized remote system access. It’s very serious as attacker can gain complete access to machine (however with privileges of currently logged user, so if you’re not using admin account all the time it’s not so serious, but how many Windows users do that). Software leaves possibility of attack on TCP port 7777 and after gaining access such activities are possible: ability to list directories, send and receive files, and execute programs. Read more in the original report. Who would even suppose that software which shows you progress of charging your batteries can bring such vulnerability? This happens when developers don’t pay attention to security, would it ever change? Ehh.
