Exploit:JS/LightSpy is one virus that uses the internet browser program’s weakness to its advantage in order to infect a computer. By secretly taking advantage of the software’s vulnerabilities, this threat infiltrates the computer via a malicious Java script file and modifies its settings.

Exploit:JS/LightSpy is a surveillance or data-stealing malware that can technically take several types of information from infected devices, such as files, images, videos, voice recordings, location, and relevant social networking information.

How does it infect the computer?

Exploit:JS/LightSpy is being deployed through a number of campaigns. In the past, the infection happened when a user clicked on a hacked news website that included articles on protests in Hong Kong and other pertinent news or subjects. This type of assault, known as a “watering hole attack,” involves hackers infiltrating reputable news websites with malicious malware. When users visit these websites, they risk having Exploit:JS/LightSpy infect their devices.

It changed recently to become a social media campaign, and to get users to click on it, phishing assaults are now used. Exploit:JS/LightSpy can be inadvertently downloaded by online users when they acquire fictitious software updates from dubious sources. The virus runs as a malicious Java script file and exploits the vulnerabilities on the system.

How does this malware operate?

It is said that Exploit:JS/LightSpy.A operates incrementally as it penetrates the computer. The virus first downloads a tool that allows it to encrypt or decode a malicious ZIP file containing executable files. This is its next payload, which it uses to access known vulnerabilities in the browser or system, particularly the WebKit weaknesses in Safari on Mac computers. After that, a shell script is used to unpack the files, giving Exploit:JS/LightSpy root access and enabling it to execute at startup.

During the last phase of the assault, the core payload—which serves as the plugin—is downloaded and executed by Exploit:JS/LightSpy. The threat actors can now use a command-and-control (C&C) server to connect directly with the compromised computer. It is further claimed that the Exploit:JS/LightSpy core payload may change the compromised device’s network configuration, work covertly within the device, and execute shell commands towards it.


When antivirus and effective security applications find evidence of Exploit:JS/LightSpy on a device, they may alert users. In addition, users could discover unwanted plugins or programs on their device that they don’t remember installing.
