The Neutrino toolkit topped the list of web attacks by toolkit again this month, although it decreased 7.6 percentage points in August to 13.9 percent of all activity. The Angler toolkit declined another 2.7 percentage points in August to 4.3 percent, though it remained in second place. The number of blocked web attacks decreased in August to 415,000 per day. The decline in web attacks is likely connected to the declines in major toolkit activity.
