Serve yourself
Invincea's report contains no justification for the unstated $250 average cost to victims of each and every impression that underlies its scary headline figure of over half a billion dollars of damage. For example, as this refers specifically to Cryptowall, mobile device users (in the majority in Blighty, according to a recent report) and Mac users (even those with Flash installed and, I know, a minority) are immune: the report discusses only Windows. Even Windows users with up-to-date malware protection have a good chance of dodging the bullet: after all, the report reassuringly describes how Invincea's software nullified the threat; it's just conceivable that its competitors could do the same.
