Infostealers series
An infostealer is a specific type of malware designed to steal as much valuable information from devices as possible. This includes locally stored files and login credentials. Session tokens, stored in cookies, are especially valuable to infostealers. Such data can be exploited to gain access to active sessions, even when multi-factor authentication (MFA) is enabled.
Infostealers often operate silently, leaving users unaware that their device has been infected. They are primarily spread through illegal software downloads and phishing attacks. Once an infostealer infects a device, it immediately starts gathering information. This can range from sensitive personal data to business-critical information, depending on the target and the specific malware.
Infostealers employ various techniques to collect data. Most focus on browsers to steal saved passwords and cookies. Others also target data from email clients or cryptocurrency wallets. The collected information is then sent to the attackers' servers, where it can be sold or used for further attacks.
The danger of infostealers lies in their invisibility and the value of the data they can steal. They often go undetected until the damage is already done, making both organizations and individuals vulnerable to data breaches and hacks.
Information security is gaining increasing attention in healthcare organizations. We spoke about this with a large healthcare organization in the south of the Netherlands. Information security is an important theme for them: they continuously map out vulnerabilities and implement improvements. One of the tools they use for this is Passguard. Why? We asked the CIO.

Infostealers are developed as Malware-as-a-Service (MaaS). This model allows cybercriminals without deep technical knowledge to gain access to advanced malware by simply paying for a subscription. This makes infostealers more accessible for a wider range of criminals to launch attacks without having to develop malware themselves.

In recent years, many organizations have implemented effective measures to secure their networks and reduce the risk of phishing attacks. As a result, the effectiveness of traditional attack methods has significantly decreased. This poses a major problem for cybercriminals, as their entire ecosystem relies on successful attacks.
