The cyber risk landscape is rapidly evolving as threat actor groups continue to launch attack campaigns with a myriad of malicious intentions. The U.K. NCSC has issued a warning about a new piece of spyware—FluBot—that is capable of stealing passwords and other sensitive information. An ongoing QuickBooks malspam campaign that targets users with the infamous Dridex trojan has also been spotted.

To minimize the impact of attacks, security vendors are always on their toes to fix security flaws, and one such major update has been shipped for Apple iOS and iPadOS 14.5. The latest version addresses around 50 vulnerabilities that could lead to multiple threats. Additionally, a zero-day vulnerability that is being wildly exploited by the Shlayer malware has also been fixed in macOS.
