Security researchers have uncovered an evolution of the LightSpy spyware, an increasingly sophisticated mobile surveillance tool targeting iOS devices with invasive surveillance capabilities. First documented in 2020, this latest version represents a significant escalation in both technical complexity and potential harm to unsuspecting users.

A Modular Threat with Expanded Capabilities

The new LightSpy iOS implant is far more than a simple tracking tool. Developed by what researchers believe are threat actors likely based in China, this spyware has dramatically expanded its functionality, now featuring 28 different plugins that can comprehensively compromise a user's device.

The spyware's modular architecture allows it to:

• Capture extensive personal information including:

  • Screenshots

  • Location data

  • Browser history

  • Contact lists

  • Call logs

  • SMS messages

• Exfiltrate data from multiple messaging apps like WeChat, Telegram, and WhatsApp

• Access iCloud Keychain

• Record audio and take camera shots

Most alarmingly, the latest version includes destructive capabilities that can:

• Delete media files

• Wipe browser history

• Remove contact information

• Potentially prevent a device from booting up

Sophisticated Infection Mechanism

The spyware leverages complex infection techniques, including:

• Exploiting known WebKit vulnerabilities (CVE-2020-9802)

• Using publicly available jailbreak techniques

• Targeting specific iOS versions (up to version 13.3)

Researchers discovered the infection likely occurs through watering hole attacks, where victims are tricked into visiting malicious web pages. Once infected, the spyware can extensively monitor and manipulate the device.

Who is at Risk?

Initial research suggests the threat predominantly targets users in China and Hong Kong. Of the eight iOS devices identified in the leaked control server data, seven were connected to a single Wi-Fi network, potentially indicating a test environment or specific targeted region. 

Clearly this capability is being refined by the adversary and is just another proofpoint for why organizations should be focused on securing all of their endpoints, including mobile devices. We are seeing threat actors and cyber criminal groups honing their tradecraft to target devices. This is one such example. 

Detection and Prevention

While the spyware is sophisticated, there are ways to protect against such threats:

1. Keep Systems Updated: Regularly install iOS updates to patch known vulnerabilities

2. Be Cautious of Web Content: Avoid clicking suspicious links or visiting untrusted websites

3. Use Security Tools: Employ comprehensive mobile security solutions, like iVerify. 

iVerify's Approach to Detection

iVerify's mobile EDR technology offers multi-layered protection against such sophisticated threats:

iOS Detection

• Capable of identifying suspicious process executions

• Analyzes system diagnostics for anomalous behaviors

Android Detection

• Our integrations with Google Play Protect to identify potentially malicious side-loaded applications

• We can detect trojanized applications typically used by LightSpy in Android environments

While complete prevention is challenging, diligent scanning, frequent updates, and using security tools designed to protect mobile devices significantly reduce the risk of such sophisticated spyware infections.

Recommendation: Stay vigilant, keep your devices updated, and leverage comprehensive mobile security solutions to protect against this evolving digital threat.
