Boffins bag side-channel bugs before they bite

Rowhammer and similar side-channel attacks aren't caught by anti-virus, so a bunch of US boffins have set about working out how to catch their signatures. Once considered the stuff of laboratories and spies, side-channel attacks have become increasingly practical. Rowhammer, for example, is a software-only way to flip bits in …
