It now boasts enhanced destructive capabilities in addition to its extensive data collection functions. This malware exploits vulnerabilities in both iOS and macOS systems, posing a significant threat to users of Apple devices.
Description
LightSpy is an advanced iOS spyware that has significantly evolved since its initial discovery in 2020, now incorporating enhanced destructive capabilities alongside its extensive data collection functions. This malware targets vulnerabilities specific to both iOS and macOS, utilizing a WebKit exploit to deliver a Mach-O binary disguised as a “PNG” file [5] [6]. Once installed, LightSpy’s Core module performs an Internet connectivity check and organizes data into subfolders for logs [2], databases [2], and exfiltrated information [2] [6]. It establishes an Internet connection and transmits data through the Baidu domain [5], creating a storage directory for logs and extracted information [5]. The spyware retrieves additional malicious components from a remote server [5], leveraging a memory corruption flaw (CVE-2020-3837) for privilege escalation and exploiting the Safari remote code execution vulnerability tracked as CVE-2020-9802 for initial access.
LightSpy operates using a modular [5], plugin-based architecture [2] [6], significantly increasing its plugins from 12 to 28 in the latest version (7.9.0) [2]. These plugins enable the spyware to capture a wide array of sensitive information, including Wi-Fi network details [2], screenshots [2] [4] [5] [6], geolocation data [3], iCloud Keychain information, audio recordings [5], photos [2] [4] [5] [6], browser history [2] [3] [4] [5] [6], contacts [2] [3] [4] [5] [6], call logs [4] [5], and SMS messages [2] [5] [6]. Notably, the plugins can also extract data from various applications such as Files, LINE [2] [6], Mail Master [2] [6], Telegram [2] [5] [6], Tencent QQ [2] [6], WeChat [2] [5] [6], and WhatsApp [2] [5] [6].
In addition to information theft [3], the updated variant introduces destructive functions that allow for the deletion of media files [5], selected SMS messages [4], Wi-Fi configurations [2] [5] [6], and contacts [4], as well as erasing browser history and freezing the device, rendering it unusable [5]. A particularly concerning feature is its ability to prevent compromised devices from booting, further complicating recovery efforts. The spyware can also generate fake push notifications with specific URLs [2]. The threat actors behind LightSpy prioritize the ability to erase traces of their activities [4], indicating a sophisticated approach to maintaining their surveillance capabilities. Although the jailbreak does not survive device reboots [3], it does not guarantee protection against reinfection [3].
The distribution method for LightSpy remains unclear [6], but it is suspected to involve watering hole attacks [6]. Investigations suggest that the operators may be linked to a state-sponsored group, likely of Chinese origin [3], as evidenced by the location plugin’s use of a coordinate system specific to Chinese map services (GCJ-02) [2] [6]. The threat actors actively monitor security research publications to exploit newly disclosed vulnerabilities [2] [6], demonstrating their advanced understanding of device vulnerabilities and their commitment to adapting tactics to infiltrate systems and extract valuable data while evading detection. Users of Apple devices are advised to apply the latest updates [1], as LightSpy exploits previously disclosed vulnerabilities [1], underscoring the ongoing adaptation of attackers to new security disclosures [1].
Conclusion
LightSpy represents a significant threat to Apple device users due to its advanced capabilities and evolving nature. The spyware’s ability to exploit known vulnerabilities and its destructive functions highlight the importance of maintaining up-to-date security measures. Users are strongly advised to apply the latest software updates to mitigate the risk of infection. The ongoing adaptation of LightSpy underscores the need for continuous vigilance and proactive security practices to protect against such sophisticated threats.
