Apple on Monday announced a hefty round of security updates that address dozens of vulnerabilities impacting both newer and older iOS and macOS devices.
iOS 17.6 and iPadOS 17.6 were released for the latest generation iPhone and iPad devices with fixes for 35 security defects that could lead to authentication and policy bypasses, unexpected application termination or system shutdown, information disclosure, denial-of-service (DoS), and memory leaks.
Apple's implementation of installing marketplace apps from Safari is heavily flawed and can allow a malicious marketplace to track users across websites
We analyzed third-party keyboard apps Tencent QQ, Baidu, and iFlytek, on the Android, iOS, and Windows platforms. Along with Tencent Sogou, they comprise over 95% of the market share for third-party keyboard apps in China. This is an FAQ for the full report titled "The not-so-silent type: Vulnerabilities across keyboard apps reveal keystrokes to network eavesdroppers."
Group-IB, a leading creator of cybersecurity technologies to investigate, prevent, and fight digital crime, has uncovered a new iOS Trojan designed to steal users’ facial recognition data, identity documents, and intercept SMS. The Trojan, dubbed GoldPickaxe.iOS by Group-IB’s Threat Intelligence unit, has been attributed to a Chinese-speaking threat actor codenamed GoldFactory, responsible for developing a suite of highly sophisticated banking Trojans that also includes the earlier discovered GoldDigger and newly identified GoldDiggerPlus, GoldKefu, and GoldPickaxe for Android. To exploit the stolen biometric data, the threat actor utilizes AI face-swapping services to create deepfakes by replacing their faces with those of the victims. This method could be used by cybercriminals to gain unauthorized access to the victim’s banking account – a new fraud technique, previously unseen by Group-IB researchers. The GoldFactory Trojans target the Asia-Pacific region, specifically — Thailand and Vietnam impersonating local banks and government organizations.
Group-IB’s discovery also marks a rare instance of malware targeting Apple’s mobile operating system. The detailed technical description of the Trojans, analysis of their technical capabilities, and the list of relevant indicators of compromise can be found in Group-IB’s latest blog post.

Unidentified governments are surveilling smartphone users by tracking push notifications that move through Google's and Apple's servers, a US...
In a letter to the Department of Justice, Senator Ron Wyden said foreign officials were demanding the data from the tech giants to track smartphones. The traffic flowing from apps that send push notifications put the companies "in a unique position to facilitate government surveillance of how users are using particular apps," Wyden said. He asked the Department of Justice to "repeal or modify any policies" that hindered public discussions of push notification spying.
