Possibly a tad disingenuous: suppose there were 5 malware items six months ago and now there are 20: saying that 15 more items exist is much less sensational than saying 400%!!! I downloaded the research/report file from Juniper but if they have actual numbers in there, not %ages, they are damn well hidden. Needless to say, all of the advanced mobile OS’es have their problems to one extent or another. If you’d like a copy of the report without doing the registration thing with Juniper let me know.
