Forget the recycle bin, here’s how to really delete files from your computer & phone

When you delete your files the regular way in Windows and Linux they are not really gone and if someone came along soon enough they can recover them.

Econet’s Ownai hit by another outage. Separately, hackers claim they attacked it

Econet’s classifieds website, Ownai, is down again. It’s not clear yet if it’s another case of lots of visitors trying to visit the site at once (they just sent out an SMS ad inviting user to the platform) or if it’s the case of hackers having hit it again.

Lax security leading to rampant website defacement

Zimbabwean websites (.co.zw TLD) are easy pickings for hacker groups making names for themselves – that is the impression I get looking at the sheer number of defaced websites. The state of local website security is appalling. After my research, the most worrying thing I found is how long some websites stay defaced, it’s almost as if […]
