Summary
Description of Campaign
Malware affecting Apple products continue to evolve. The XCSSET malware has evolved to include the ability to steal data from Chrome and Telegram, as well as valuable information from apps such as Evernote, Opera, Skype, WeChat, and Apple's own Contacts and Notes apps. The current list of IOCs reported in the blog do not have information available through VirusTotal, so lethality cannot be determined at this time.
