Seidr Stealer Malware: Threat Overview and Removal Guide

Trojan malware, commonly known as “Trojans,” is a type of malicious software designed to infiltrate systems by disguising itself as legitimate programs or files. Once installed, Trojans can steal sensitive data, disrupt systems, or grant attackers control over the infected computer. The term “Trojan” originates from the myth of the Trojan Horse, symbolizing how these threats gain entry through deceptive means. Trojans typically spread through phishing emails, malicious downloads, or compromised websites, posing significant threats to personal data and financial security.

Understanding Seidr Stealer

Seidr is a dangerous stealer-type Trojan malware that primarily targets sensitive user information such as saved passwords, autofill data, and cryptocurrency wallets. It operates by extracting data from Chromium and Gecko-based browsers and functions as a keylogger, recording keystrokes, and a clipper, which hijacks cryptocurrency transactions by modifying clipboard addresses. Seidr’s primary installation method includes phishing emails and bundled downloads. Once installed, it can severely compromise the user’s privacy and finances, leading to identity theft and major financial losses.
