Apple has delivered a big batch of OS updates, some of which belatedly patch older versions of its operating systems to address exploited-in-the-wild flaws the iGiant earlier fixed in more recent releases.

The attackers are working on a number of malware threats, some of which have been used in attacks while others are in pre-deployment or testing stages.
Symantec, by Broadcom Software, has gained insight into the current activities of a group we call Webworm. The group has developed customized versions of three older remote access Trojans (RATs), including Trochilus, Gh0st RAT, and 9002 RAT. At least one of the indicators of compromise (IOCs) observed by Symantec was used in an attack against an IT service provider operating in multiple Asian countries, while others appear to be in pre-deployment or testing stages.
