What is an Infostealer

An Infostealer differs from other malware in its specific objective. While viruses replicate themselves or ransomware encrypts data, Infostealers focus exclusively on stealing sensitive information. This includes, among other things:

• Access data for online accounts
• Credit card information
• Browser history and saved passwords
• Crypto wallet data
• Screenshots and keystrokes

Distribution channels & risks

Infostealers often get onto a system through fake software downloads, infected email attachments or compromised websites. Particularly perfidious: some variants modify themselves after installation in order to evade detection by anti-virus software.

A veritable trade in stolen access data is flourishing on the Darknet. Depending on the type and quality of the information, prices range from a few cents to several thousand euros for complete digital identities.

Well-known Infostealer groups:

• Raccoon Stealer: Specializes in browser data and crypto information.
• RedLine Stealer: Targets stored passwords, payment information and network access.
• Vidar Stealer: Modular design to collect specific data.
• Aurora: Highly sophisticated and particularly dangerous for corporate networks.

Cybercrime as a business model

The increasing professionalization through Infostealer-as-a-Service models is worrying. Attackers no longer even have to develop their own malware, they can rent it. This drastically lowers the barrier to entry for cyber criminals.

Protection from infostealers

Effective protection is made up of several components:

• Technical measures: Robust security software such as the DEFENDERBOX can detect suspicious activity at an early stage.
• Raising employee awareness: Many infections are caused by human error. Regular training helps to minimize risks.
• Zero trust principle: Minimization of rights and access levels in the company.
• Regular updates: Operating systems and software should always be up to date in order to close security gaps.

The cyber threat from infostealers is becoming increasingly sophisticated. A holistic approach to security is therefore essential to protect companies and users.
