Please note: I do not handle acute ransomware cases myself. However, I can provide experienced experts if required – for example for professional negotiations with blackmailers or for short-term crypto liquidity procurement.
Introduction
Ransomware is a form of malware that encrypts company data and only releases it again against payment of a ransom. These attacks are on the rise worldwide and cause enormous economic damage. Companies in particular are targeted, as they often pay faster than private individuals – and the attack surface is larger.
Die Anatomie eines Ransomware-Angriffs
How attacks work: From infection to blackmail
Typically, an attack begins with a phishing email or an infected attachment. If this is opened, the ransomware installs itself unnoticed, spreads in the company network and systematically encrypts files and often even creates a backup. A message then appears with a ransom demand.
Typical weak points in companies
Unpatched software, unsecured remote access and a lack of employee training are among the most common vulnerabilities that cyber criminals exploit. Companies without up-to-date backups and structured emergency plans are particularly at risk.
Which sectors are particularly affected
The healthcare sector, financial service providers and medium-sized industrial companies are particularly vulnerable – partly due to sensitive data and partly due to low IT security standards.
Negotiating with blackmailers: A risky balancing act
Why responding to demands is dangerous
The payment of a ransom offers no guarantee that data will be returned. Normally, however, the blackmailers stick to the agreements as otherwise no company would pay any more. It also motivates further attacks and can have consequences under criminal law or insurance law.
Who should negotiate – and who shouldn’t
Negotiations should never take place without legal, official and technical advice. There are specialized service providers who are familiar with such situations and can act with legal and tactical certainty.
Psychological tactics of blackmailers
Ransomware attacks are not only technical, but also psychological attacks. The blackmailers use fear, time pressure and threats to force companies to pay – often very professionally. Their methods follow a clear pattern based on psychological manipulation.
Typical tactics are:
- apparent willingness to engage in dialog in negotiations – in order to build trust and at the same time exert further pressure.
- Countdown timers that suggest an “expiring chance” for data recovery,
- the threat of making stolen data public or passing it on to customers/media,
- References to allegedly already published evidence or “observers” in the network,
Financial consequences and liquidity problems
Immediate financial impact of an attack
Production stoppages, loss of customer confidence and high recovery costs are just some of the immediate consequences. Added to this are possible fines and legal costs.
Why cyber insurance is often not enough
Many policies do not fully cover ransomware cases or contain complex exclusion clauses. Insurers also require proof of security measures.
Procuring liquidity during the crisis
Whether through interim financing, credit lines or equity capital – quick action is required in a crisis. Specialized consultants can help you develop the right strategy.
Restoration and data recovery
Challenges in data recovery
Even if payment is made, it remains unclear whether all data will be fully decrypted. Some files may remain damaged or not be recovered at all, but here too the blackmailers usually stick to the agreements.
Role of backups and emergency plans
Backups and emergency plans are essential components of IT security, especially in the fight against ransomware. They make it possible to restore systems after an attack and continue operations as quickly as possible. However, backups do not always work as hoped – for example, if they have also been encrypted or deleted. This is why offline backups, i.e. backups that are completely separate from the network, are particularly important. They offer significantly greater protection against ransomware as they are not directly accessible to attackers.
But even a functioning backup does not protect against data leaks. Many ransomware groups steal sensitive data before encrypting it. If no ransom is paid, they threaten to publish the information. In some cases, they go even further: they use stolen customer data to contact affected individuals directly and exert pressure on the company. This makes it clear that backups are only part of the protection – prevention, education and a comprehensive emergency plan are just as important.
When external specialists can help
External IT security specialists can provide crucial assistance in a ransomware case – especially if there is a lack of expertise or resources internally. They provide support in the technical analysis of the attack, the identification of vulnerabilities and help to assess the extent of the damage. They can often also help to restore systems and check whether and what data has been leaked.
They also have experience in dealing with blackmailers, provide support in preserving evidence for law enforcement authorities and advise on legal and communicative steps, for example in dealing with customers or data protection authorities. External help is particularly worthwhile when things need to happen quickly – and when any mistake could have expensive consequences.
Legal and regulatory pitfalls
Reporting obligations and GDPR
A ransomware attack is not only a technical problem, but also a legal one – especially if personal data is affected. In this case, the General Data Protection Regulation (GDPR) applies, which stipulates clear reporting obligations.
As soon as there is a suspicion that personal data has been compromised by an attack – for example through unauthorized access, encryption or data leakage – the incident must be reported to the responsible data protection authority within the first of the respective country. The period begins from the time at which the company becomes aware of the data breach.
In addition to the authorities, affected persons must also be notified if they are at high risk – for example, if sensitive health, financial or customer data has been disclosed. Companies are obliged to provide transparent information about the type, scope and possible consequences of the breach and to explain the measures taken or planned to limit the damage.
A breach of these reporting obligations can lead to high fines – in addition to the reputational damage that such an incident entails anyway. It is therefore important to include clear processes for reporting and communication in the emergency plan.
Cooperation with authorities
Many companies are reluctant to involve the police or other authorities in the event of a ransomware attack – for fear of reputational damage, unpleasant questions or bureaucratic red tape. But this hesitation can pay off.
The involvement of law enforcement agencies brings clear advantages: The police, especially cybercrime units, have experience in dealing with digital extortion and are familiar with current perpetrator groups, extortion patterns and technical traces. They can help companies to secure evidence, document digital evidence correctly and thus enable criminal prosecution – often in cooperation with international partners such as Europol or Interpol.
In addition, investigating authorities are increasingly showing themselves to be supportive and cooperative instead of acting exclusively in a controlling manner. In many cases, affected companies even receive specific recommendations for action and technical advice, e.g. on known decryption tools that can help without paying the ransom.
It is also important to note that in the event of reportable data breaches (e.g. under the GDPR), there is a legal obligation to be transparent with the authorities anyway. A proactive approach to the incident – including the involvement of the police and data protection authorities – shows a sense of responsibility and can help to maintain the trust of customers and partners in the event of a crisis.
Legal gray areas in ransom payments
The decision as to whether a company pays a ransom in the event of a ransomware attack is a delicate one – not only ethically and economically, but also legally. In some countries, payment to certain groups or individuals may be punishable by law, especially if they are on sanctions lists.
Many ransomware groups operate internationally and are suspected of being linked to terrorist organizations, state-controlled hackers or criminal networks. If these groups are subject to UN, EU or US sanctions, a payment – even if it is intended to restore systems – can be seen as financing a sanctioned organization. This can have serious legal consequences for the company concerned and also for the individuals responsible.
It is therefore essential to obtain a legal assessment from a specialized lawyer before making any decision on a ransom payment. This should check in particular:
- Whether the attackers can be assigned to a sanctioned group,
- which legal obligations arise from data protection and criminal law,
- whether there are alternatives to payment (e.g. decryption tools, recovery from backups),
- and how communication with authorities and customers should be legally compliant.
Furthermore, even if a payment is legally permissible, the attackers do not guarantee that data will be restored or not published. Payment should therefore always be a last resort – and should only be made with legal, technical and strategic advice.
Prevention and long-term protection
IT security audits and vulnerability analyses
Regular external security checks – such as penetration tests, vulnerability scans or audits – are a central component of an effective IT security strategy. They help companies to identify technical and organizational security gaps at an early stage before attackers can exploit them.
In contrast to internal checks, external specialists bring a neutral perspective, up-to-date knowledge of threats such as ransomware and attack techniques as well as experience from other industries and cases. They simulate real attacks, test systems specifically for weaknesses and often uncover gaps that are overlooked internally – for example, incorrect configurations, outdated software or unprotected interfaces.
But recognition alone is not enough. Any weaknesses found must be documented, evaluated and prioritized for rectification. Particularly critical are gaps that:
- can be exploited remotely,
- Enable access to sensitive data,
- or allow the extension of rights and system takeover.
A structured treatment of weak points should:
- Record technical details and risk classification,
- Define responsibilities and deadlines for rectification,
- and a retest after implementation.
A continuous review and improvement process is the only way to sustainably increase security levels and resilience. In addition, regular audits create verifiability vis-à-vis supervisory authorities, customers and insurers – an important argument in the event of an incident.
Employee training
Despite firewalls, virus scanners and zero-trust architectures, humans remain the biggest gateway for cyberattacks. Studies show that the majority of successful attacks – particularly those caused by ransomware or phishing – can be attributed to human error: a careless click, a password that is too simple or ignoring warnings is often enough to paralyze an entire company.
Regular training for employees is therefore not a “nice-to-have”, but a key safety measure. It is not only important to impart knowledge, but also to actively train realistic scenarios, e.g:
- Fake e-mails (phishing simulations),
- Social engineering attacks by phone or messenger,
- or unusual login attempts and alarm messages that need to be classified correctly.
The aim of such training courses is to strengthen security awareness in the long term, recognize typical attack patterns and react correctly in an emergency. Formats such as
- Interactive online training with tests,
- Live simulations in real time,
- Role plays or simulation games, e.g. for decision-making in an emergency,
- and short, recurring “security awareness nuggets” in everyday working life.
Important: Training should be tailored to the respective target group – from the IT team to specialist departments and management. This is because each role harbors its own risks and vulnerabilities.
An informed, aware employee is the first line of defense against cyber threats – and often the difference between a thwarted attempt and a successful attack.
Risk minimization strategies
Effective protection against ransomware and other cyber attacks begins with technical security measures that go beyond basic protection. Three central pillars here are: Network segmentation, multi-level authentication and real-time monitoring.
1. segmented networks
Instead of operating a large, interconnected network, companies should divide their IT infrastructure into clearly separated zones – e.g. according to departments, security levels or functional areas. This prevents malware (ransomware) or attackers from spreading laterally in the network (lateral movement) after initial access.
Advantages:
- Containment of attacks,
- better control over data flows,
- Targeted security measures for each segment (e.g. different firewalls, access restrictions).
2. multi-factor authentication (MFA)
Strong access controls are crucial – especially for administrator access, cloud services or remote connections. Multi-level authentication, such as the combination of password and one-time code (e.g. via app or token), makes it much more difficult for attackers to gain access to sensitive areas – even if a password has been compromised.
Best Practices:
- MFA mandatory for all external access,
- Use of hardware tokens or biometric verification,
- Regular review of privileged accounts.
3. real-time monitoring
Continuous, intelligent monitoring detects unusual behavior, such as suspicious data movements, login attempts or network traffic – often before any damage is caused by ransomware. Modern solutions use AI-based anomaly detection and can automatically raise the alarm or block processes.
In addition, there should be clearly defined response processes: Who is informed? What is shut down and when? How is the escalation handled?
4. selection of trustworthy service providers
External IT service providers, cloud providers or maintenance partners also pose a ransomware risk if their security standards are inadequate. Companies should therefore:
- Conduct regular access reviews and audits.
- Check service providers carefully and secure them contractually (e.g. via AV contracts, SLAs),
- Only use providers with proven security certification (e.g. ISO 27001, BSI C5),
7 fatal mistakes when dealing with ransomware
- No emergency plan in place
- Conduct negotiations yourself
- Missing backups
- Communication not secured
- Do not seek external help
- Do not involve authorities
- Security measures do not improve after attack
Conclusion
Ransomware is a real and growing threat for companies of all sizes. Prevention, professional help and a well thought-out crisis plan are the best means of avoiding economic and operational damage. Technical measures are not a panacea – but they form the backbone of resilient IT. The risk of an attack can only be significantly reduced through a combination of structural design, strict access controls, employee training, intelligent monitoring and the selection of reliable partners.
