When organizations hire an external security provider, they often receive reports full of technical findings but remain responsible for the follow-up themselves. Earth Grob, Business Unit Manager Cybersecurity at Vooruit, sees this as a fundamental flaw in the cybersecurity market.

IT service provider Vooruit is adding infostealer monitoring to its security portfolio. The expansion stems from a partnership with Dutch cyber intelligence company Passguard. With this new service, customers gain visibility into infected devices whose data is being traded on criminal marketplaces. Infostealers represent a rapidly growing threat, as criminals can use stolen session tokens to bypass even multi-factor authentication.

This way, we take action before the attack is launched”, says Rogier Fischer, CEO of Hadrian

Recently, Tom Leijte spoke with Security Innovation Stories, a platform that gathers innovative stories from the cybersecurity sector. In this interview, Tom not only shared insights into the world of infostealers but also revealed the story behind the founding and mission of Passguard.

After the media exposure about infostealers at RTL News and AD, we received a lot of questions. A frequently asked question, including on Reddit, was: “Why do you specifically recommend Sophos to combat infostealers?” A fair question, and in this blog post, we would like to take you into account our considerations.

An infostealer infection means that your data is in the hands of cybercriminals. If you've been notified of an infostealer infection on your device, it’s important to act quickly. This way, you can prevent further damage. In this guide, you’ll read what an infostealer infection means and the three steps you need to take to limit the consequences.

When there are indications that an infostealer is active within your organization, it’s a serious concern. Infostealers allow attackers to steal login credentials, passwords, and sensitive data from your organization, potentially leading to data breaches and hacks.

Following the news about the tens of thousands of Dutch victims of infostealers, RTL News tech reporter Daniël Verlaan was invited to the desk at RTL Z. During the interview, Verlaan shared insights into the research and operation of infostealers.

Following the report on RTL Nieuws, Algemeen Dagblad reached out to Passguard for an interview with our founders, Tom and Sanno, about the dangers of infostealers.

Infostealers are causing thousands of victims, including in the Netherlands. Research that we carried out together with RTL News shows that more than 40,000 Dutch people have already been infected with this dangerous malware. As a result, passwords, private data and business data are out on the street.

Infostealers are on the rise, and with them, the statistics tracking this growing threat. Many companies publish reports, but what do those numbers really mean? We delved deeper into the data to give you the full story. No time to go through it all? Our Passguard rating system scores the value of statistics on a scale from 1 to 5. Convenient, right?

The Graafschap College, a medium-sized vocational school in Doetinchem, has around ten thousand students and over a thousand employees. Rob Gerritsen, Chief Information Security Officer (CISO) at Graafschap College, gained insight into his organization's dark web exposure through Passguard. During a walk through a wintery forest near Doetinchem, he spoke to us about his experiences.

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.

Royal FloraHolland, the leading international marketplace for floriculture, is also a frontrunner in cyber security. As a co-initiator of the Greenport Cyber Resilience Center, they provide growers and buyers with essential protection against digital threats through their RFH Cyber Subscription. To address the challenge of infostealers, Royal FloraHolland uses Passguard. Why? We spoke to Bas Wevers, Chief Information Security Officer (CISO) at Royal FloraHolland.

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.

Preventing infostealer infections can be broken down into two key steps. While the first step is usually relatively straightforward, the second is often much more challenging.

If you suspect that your organization is dealing with an infostealer infection, it’s crucial to act quickly and decisively. Follow these steps to get the situation under control and prevent further damage.

How does an attack on an organization using an infostealer unfold? Examining examples such as Uber and EA Games reveals a four-step plan utilized by attackers to target an organization.

It may sound a bit crude, but we often compare infostealers to dog poop: they don’t come flying at you, but you simply step into them. In other words, infostealer infections are almost always the result of user behavior. At this stage, infostealer attacks are generally not yet targeted at specific organizations or users.

Managing the infostealer risk is challenging not only because of the versatility and stealthy nature of this malware but also due to where the risk primarily occurs: on unmanaged devices that have access to internal environments, such as employees’ personal laptops or suppliers’ computers.

Nearly thirty applications, only ten selected: on October 3rd, Passguard joined nine other startups at the Cyber Investor Days in The Hague, organized by the European Cyber Security Organisation (ECSO) in collaboration with Women4Cyber, TIN Capital, InnovationQuarter, KPN Ventures, Security Delta (HSD), and the City of The Hague.

If an employee's device is infected with an infostealer – even if it’s not a managed device – the attacker has the same access to internal systems and data as the employee does through that device. This access poses a significant risk for organizations and can result in data breaches and hacks.

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.

Government agencies rarely give explicit attention to the growing threat of infostealers, but Down Under, that's changing. The Australian Cyber Security Centre (ACSC) recently released their report The Silent Heist, a deep dive into the infostealer ecosystem. Here are the five most important findings.

It’s one thing to hear from a vendor how well their solution works, but it’s far more powerful to hear from a customer how that solution is applied in practice.

With 12,500 employees worldwide, dozens of shipyards, and a turnover of several billion euros, Damen Shipyards is the largest shipbuilder in the Netherlands. In addition to civilian vessels, Damen is also active in the construction of military ships for navies and coast guards. To map out dark web data and infostealer infections, it uses Passguard. Hans Quivooij, CISO of Damen Shipyards, explains why.
