Researchers at the security firm FireEye Labs Advanced Reverse Engineering said on Thursday that the malware, dubbed “IRONGATE,” affects Siemens industrial control systems. Siemens has thousands of these systems controlling Power Plants and industrial facilities all over the world.

The research team doesn’t think that Irongate is written by the Stuxnet’s authors, as Irongate is not the type of sophistication one would expect from a nation state. But the question still remains: Who did write Irongate?

Once Unlocker sets files free, Eraser lets you, well, erase them. For folks who handle sensitive data or simply love the feel of tinfoil hats—hey, I’m one of you—Eraser’s ability to delete data securely and permanently will be welcome indeed.

What’s more, Eraser lets you choose how many times you’d like to overwrite a file. Looking for a simple, single pseudo-random data pass? Maybe a Department of Defense-approved, three-times-through-the-shredder, or the full-on, 35-pass Gutmann treatment? Eraser’s got you covered.

The fact that Eraser embeds itself in your right-click context menu and allows scheduled wiping of specific folders and files is just icing on the permanent-deletion cake. Again, though: Be careful where you point this thing. What’s erased can’t be un erased.
