Meanwhile the Neutrino toolkit increased almost 10 percentage points in June. This toolkit was particularly active in the later part of the month, around the same time Angler saw its deepest decline. This decline in Angler activity follows the disappearance of the Nuclear and Spartan toolkits from our top five list over the past two months, along with a lull in activity from a number of threat groups.
Manual Sharing continues to dominate social media scams, increasing more than 20 percentage points. Fake Offers decreased in June, down from 25.68 percent in May to 12.17 percent in June.

There was one new Android malware family discovered during June. The number of Android variants per family continues to increase, reaching 53 in June. This indicates that attackers could be finding success with existing Android families, as opposed to creating new ones.
