How Does Spyware Work?

How Does Spyware Work?

Spyware works by infiltrating a device and monitoring user activity without detection. This can be done through several methods, such as:

  • Drive-by downloads: Spyware can be installed on a device when a user visits a compromised website or clicks on a malicious advertisement.
  • Phishing emails: Attackers can send emails containing malicious links or attachments, which, when clicked or downloaded, can install spyware on the device.
  • Software bundles: Spyware can be bundled with other software programs, such as freeware or shareware, and installed when the user downloads and installs the legitimate program.
  • Exploiting vulnerabilities: Spyware can take advantage of security flaws in software or operating systems to infiltrate a device and gain unauthorized access.

Once installed, spyware can run in the background, hidden from the user. It can monitor and record various types of information, such as keystrokes, browsing history, and files accessed.

This information can then be transmitted back to the attacker, who can use it for malicious purposes.

Now, for this spyware guide, I will reveal the signs of spyware.
