Highlights:
- Cybercriminal gangs use public relations tactics like press releases to build a strong image, increasing victim fear and urgency to pay the ransom.
- While zero-day vulnerabilities are hard to protect against, enterprises can boost their defenses by unifying skilled personnel with cutting-edge threat intelligence.
For the last five years, the ransomware landscape has been transformed completely. Disorganized gangs have updated into sophisticated ransomware businesses, focusing on giant organizations with planned attacks to extort massive sums.
Today, “Big-Game Hunting” utilizes cross-platform ransomware and the technique of “double extortion.” In this scenario, criminals threaten to expose sensitive data unless the ransom is paid.
The further information below provides answers to three essential questions surrounding targeted ransomware attacks.
- How attackers select their targets.
- How attackers make their strategies.
- Why do mature organizations fall victim to attacks.
Ransomware: Brand-building by Criminals
It’s necessary to realize how these criminal networks work to get a clearer understanding of what types of victims they target and how they achieve their objectives.
With the advent of big-game hunting, we’ve seen the rise of well-known groups in the ransomware space, such as Maze, Conti, and REvil.
The above groups have known that creating a strong “brand presence” (through techniques like press releases) enhances their credibility, making victims likely to pay urgently.
However, this branding can create the illusion that a single entity is behind these attacks when it’s an intricate network of independent actors connecting through dark web marketplaces.
These criminals don’t need personal connections; they interact using online aliases and pay for services with cryptocurrency.
This decentralized structure is one reason why paying ransoms is strongly discouraged. Tackling a criminal network needs a systematic approach, like disrupting the flow of money within it. Arresting one entity won’t have a significant impact, as others will fill the gap speedily.
How Does a Ransomware Attack Work?
Ransomware attacks are a major cybersecurity threat, including the encryption of a victim’s data and necessitating payment for its release.
Understanding how ransomware compromises systems, locks data, and pressures victims into paying can assist in preventing, detecting, and responding to these attacks.
The process is like this:
- Initial access
The first group, known as Botmasters and Account Resellers, aims to access as many potential victims as possible by installing malware and exploiting network vulnerabilities. They then sell this access to interested parties, such as ransomware criminals, as a profitable resource.
- Infiltration
Next, a different group, often referred to as Partners, Affiliates, or The Red Team, uses this initial access to compromise the system carefully. This stage can cover months as they gain administrative privileges, deploy backdoors, and take out valuable data to use for extortion. They might also enlist independent analysts to evaluate the target’s financial status, the value of the stolen data and set the highest possible ransom.
- Deployment
When the red team is ready to deploy ransomware, they don’t utilize their own software. Instead, they purchase a user-friendly ransomware kit from Ransomware Developers on the Dark Web, who sell these kits for a cut of the ransom. This “Ransomware-as-a-Service” (RaaS) model lowers the technical skills required to proceed with the attack.
- Negotiations
Lastly, another specialized team manages the ransom negotiations and processes the cryptocurrency payment.
Why Are Ransomware Attacks Often Effective and Straightforward to Implement?
Ransomware attacks are primarily driven by opportunity rather than strategic planning. Let’s have a look ransomware attack targeting of a pray:
- Ransomware attack: soft spot
The core insight is that these attacks aren’t directed by criminal masterminds carefully researching their next victims.
Rather, they resemble opportunistic thieves who capture poorly protected targets with valuable assets. Hence, labeling a ransomware attack as “targeted” can be deceptive.
This insight is important for organizational defense against ransomware: By addressing basic system vulnerabilities, you can stop cyber-criminals from gaining a base set.
- Vulnerable targets: a closer look
While ransomware can have an impact on different industries, industrial businesses, public institutions, and sectors such as healthcare, education, IT, and finance are specifically vulnerable. These enterprises are major targets due to their:
- Companies offering critical services
- Vast amounts of sensitive data
- Overlooked security weaknesses
To gain a comprehensive knowledge of the issue, we must study why these fields are so desirable to cyber criminals and how even big organizations with significant security budgets can become victims of this.
Cybersecurity Weaknesses in Large Organizations: 5 Compounding Factors
Outdated systems, expanded attack surfaces, tool overload, cybersecurity talent gaps, and human error unifies to create vulnerabilities in giant organizations, making them major targets for ransomware attacks.
It includes:
- Obsolete software and equipment
Legacy systems are grappled with known vulnerabilities that criminals can quickly exploit. These vulnerabilities are openly documented, making them available to anyone with harmful intent.
The concern lies in continuously upgrading software and fixing vulnerabilities, a task frequently avoided by public institutions. Employing a strong patch management strategy can considerably lessen the risk of falling victim to an attack.
While zero-day exploits are more challenging to defend against, enterprises can reduce risks by inserting well-trained security teams integrated with modern threat intelligence.
Moreover, bug bounty programs provide a strategic approach by stimulating ethical hackers to pinpoint vulnerabilities before malicious actors can infiltrate them.
- Extended attack surface
Advanced organizations come across a growing attack surface because of complex IT environments.
The quick shift to remote work has degraded this, with enhanced vulnerabilities from:
- Home networks
- Third-party services
- Remote access tools
Finally, cybercriminals exploit these weaknesses, often targeting VPNs and RDP for entry.
- Overburdened security posture
Many large enterprises have gained a vast array of security tools without a unified strategy. This tool proliferation frequently hinders rather than enhances security.
Without seamless integration, security teams are overwhelmed by data overload, making it challenging to identify threats, specifically those employing advanced evasion techniques.
As a result, they struggle to respond effectively to incidents.
- The cybersecurity talent shortage
The cybersecurity industry is experiencing a lack of skilled professionals. Struggling against sophisticated attacks targeting large organizations demands highly trained experts.
This makes public sector entities vulnerable, as leading talent is frequently lured away by higher-paying private sector roles.
- Human error
It is a constant vulnerability across all organizations. Attackers frequently infiltrate gullible employees to breach systems, a problem potentially exacerbated in public sectors with lower cybersecurity awareness.
Social engineering attacks such as phishing, vishing, and smishing are commonly used to trick users into installing malware or finding sensitive information.
Finally, these attacks can be integrated with other vulnerabilities, like exposed remote access services, to build highly effective and targeted cyberattacks.

Concluding Lines
To combat sophisticated and widespread ransomware threats, enterprises need a multi-layered, comprehensive strategy.
This consists of proactive prevention, advanced threat detection, robust incident response, and effective data protection. Since ransomware is continuously growing, current vigilance and investment in cybersecurity are necessary.
Finally, creating a security-aware culture is key to combating risks. A holistic approach that tackles human, technological, and operational aspects will efficiently reduce the risk of ransomware and boost organizational resilience.
