Infostealers

Infostealers are a type of malware designed to steal sensitive information from infected computer systems. This information can include login credentials for websites and online services, financial details like credit card numbers and bank account information, personal identification data, and browsing history. Infostealers typically operate by searching the compromised system for stored data or by actively monitoring user activity to capture credentials as they are entered.

The methods employed by infostealers vary. Some may inject malicious code into web browsers to intercept data entered into forms or to redirect users to fake login pages. Others might target specific applications known to store valuable information, such as password managers or email clients. The stolen data is then exfiltrated, often sent to a remote server controlled by the attacker.

Infostealers can be distributed through various means, including malicious email attachments, compromised websites, or bundled with seemingly legitimate software downloads. Users can protect themselves by practicing safe browsing habits, using strong and unique passwords, keeping software updated, and employing reputable antivirus and anti-malware solutions. The primary goal of infostealers is to gain unauthorized access to personal and financial accounts for fraudulent purposes, such as identity theft or financial gain.
