The term 'ransomware' has become ubiquitous in the cybersecurity lexicon, notably due to high-profile cases that have made headlines. However, beyond these spectacular affairs, ransomware constitutes a serious and often underestimated threat, given that many incidents are never reported.
Definition from ANSSI: Ransomware consists of sending the victim malicious software that encrypts all of their data and demands a ransom in exchange for the decryption password.
As one can imagine, being taken hostage in this way can have devastating consequences for businesses, ranging from the loss of important data to significant financial damages, not to forget the long-term reputational damage that can prove even more costly.
Take the example of WannaCry, a cluster of attacks that took place in 2017. This ransomware affected hundreds of thousands of computers in 150 countries. The victims were not only large corporations; even small structures like local bakeries, schools, and hospitals were affected. It wasn't just an attack for money; the motives were also geopolitical. The scale of these attacks underscored the urgent need for all businesses to take the ransomware threat seriously.
It is crucial to know the different forms that ransomware can take:
Ransomware has become an industry in itself. Cybercriminals rent out their ransomware infrastructure to others, known as "Ransomware as a Service (RaaS)."
The best defense is often a good offense, so let's understand how to anticipate these virtual threats and go on the offensive!

Understanding ransomware is the first step towards protecting your business.
Stay with us for the rest of this guide where we will teach you how you can defend against these threats!
The first and perhaps most essential step in defending against ransomware is prevention. Imagine you are in the heart of a lush forest where each attack vector represents a different path that ransomware could take to harm you. Among these paths, phishing and unsafe web browsing are often the most traveled.
So let's examine these potential vulnerabilities in detail to better understand how to effectively protect ourselves!
Deceptive emails from seemingly reliable sources can hide malicious links or attachments. A simple click and the ransomware finds its way into your system, often without your knowledge. Similarly, visiting malicious or compromised websites can also lead to an unwanted installation of ransomware.

Let's not forget that some ransomware, like WannaCry, exploited flaws in well-known protocols to spread. And it's not just attachments or links that are dangerous; sometimes, even malicious advertisements on otherwise legitimate websites can serve as a springboard for these malware.
To face this multitude of threats, a multi-layer approach is necessary. This involves continuous employee training, a robust company security policy, and of course, technological solutions. After all, in cybersecurity, human error often remains the weakest link.
We've covered common attack vectors and preventative measures to avoid ransomware. However, what do you do if, despite all these precautions, you believe you're the victim of a ransomware attack? Here are some tips on the first steps to take.
The first symptoms of a ransomware attack can be subtle. Signs such as system slowdown, frequent crashes, or unexpected popup windows are all clues that should put you on alert. You may also notice that certain files have become inaccessible or have been renamed.
If you have any doubt, it is crucial to report it immediately. Get in touch with your organization's IT department, which can assess the severity of the situation and, if necessary, alert the authorities and cybersecurity experts.
If your IT department is unavailable and your suspicion is strong, consider isolating the affected workstation by disconnecting it from the network. This step is essential to prevent the spread of the ransomware to other systems.
Once the attack is confirmed, the recovery phase can begin. Depending on the context, this may include restoring systems from reliable backups, removing the ransomware using specialized software, or, in extreme cases, completely rebuilding the systems.
In summary, knowing how to react in the event of a ransomware attack is crucial, but so is preparation beforehand. If you have doubts about the security of your systems and your protection against ransomware, do not hesitate to contact us at Qontrol.

The use of ransomware exposes its authors to criminal prosecution. However, the international scope of cyberspace makes it difficult to identify and prosecute cybercriminals.

The ethical dilemmas associated with ransomware are numerous. One of the most debated is the payment of the ransom. Although this option may seem like a quick way to recover critical data, it also contributes to the funding and proliferation of these cyber threats. The ANSSI (French National Agency for the Security of Information Systems) recommends never paying the ransom for various reasons, including the risk of future attacks.
Regrettably real examples illustrate these dilemmas. In 2021, the Rouen University Hospital was forced to postpone non-urgent interventions and revert to using paper records following a ransomware attack. In the United States, the Hollywood Presbyterian Medical Center hospital chose to pay the ransom to restore access to its systems, a decision they deemed necessary despite the associated risks.
According to IBM, nearly half of the businesses victimized by ransomware end up paying the ransom. But beware, payment does not always solve the problem. Some businesses that paid a ransom faced other issues, such as another attack or the disclosure of their data.
A Lifeline?What is Cyber Insurance?Cyber insurance is a specific coverage designed to manage risks related to computing and online activities. It can help cover the costs associated with a ransomware attack, including data recovery, legal fees, and, in some cases, the ransom payment. Some policies also offer incident response services, including advice from cybersecurity experts.
Not a Silver BulletHowever, it is crucial to understand that taking out cyber insurance does not eliminate the risk of attack. It's not an immunity card, but rather a financial safety net. Moreover, most insurance policies have exclusion clauses and specific conditions - including the implementation of a robust security foundation. It is therefore imperative to read your contract carefully to know what is really covered.
Insurance companies may require that you have taken certain precautions to secure your systems, such as using up-to-date security software, conducting cybersecurity training for your staff, and developing incident response plans. Furthermore, for some businesses operating in regulated fields like finance or health, or those aiming for certifications such as ISO 27001, subscribing to cyber insurance can become a mandatory requirement.
We have explored the complex world of ransomware, from prevention to response in case of an attack. The key message remains the same: prevention is the best cure. By investing in a comprehensive cybersecurity approach, you can not only protect your business but also save yourself from difficult and costly decisions in the future.
