Software updates often take a back seat, especially in small businesses with limited time and resources. But when a system falls behind on updates, it becomes an easier target for hackers.
According to the study Cost of Cybercrime Accenture, 43% of cyberattacks target small businesses and only 14% of them are prepared to defend themselves. Many businesses rely on a mix of old and new software, unaware that this can open doors to serious security breaches.
An outdated program is not just outdated, it can lead to data loss, ransomware and financial damage to the entire company, explains the global digital security company ESET.
To protect yourself, you first need to understand exactly how hackers exploit these vulnerabilities. See exactly how hackers exploit these vulnerabilities and what you can do to stay one step ahead.

Exploiting unpatched vulnerabilities
One of the most common ways hackers penetrate systems is by exploiting unpatched vulnerabilities. The Data Breach Investigation Report Verizon for 2024 showed that 14% of breaches involved exploiting vulnerabilities, which is almost three times the rate in 2023. Although software developers release updates to fix bugs, improve functionality, and plug security gaps, if these updates are not installed in a timely manner, companies' systems are exposed to attackers looking for such vulnerabilities. Unpatched vulnerabilities were at the heart of the infamous attack WannaCry ransomware, which caused damage billions of dollars worldwide.
Automating the update process minimizes the potential for human error or oversight. Tools like patch management solutions can automatically identify outdated software, download the necessary updates, and deploy them to an organization. But not all updates are created equal. Critical updates should be prioritized to address critical vulnerabilities. Organizations can adopt a risk-based approach to ensure that high-risk vulnerabilities are addressed first. Performing routine scans to identify software gaps ensures that no critical updates are overlooked.

Attacks on legacy systems
Legacy systems are often the backbone of critical operations in hospitals or the public sector. Cybercriminals exploit these outdated systems, knowing that they are often deeply embedded in an organization’s workflows and contain valuable data. The consequences of an attack on legacy systems can be significant, affecting everything from supply chain operations to customer trust.
However, if replacing these systems is not immediately feasible, organizations should implement alternative solutions. For example, isolating legacy systems from the rest of the network through partitioning reduces the potential attack surface. In the event of a breach, the damage can be contained, preventing further spread. For systems that cannot be updated, virtual remediation involves deploying security tools that simulate an updated patch, detecting and blocking attempts to exploit known vulnerabilities. While complete replacement of legacy systems may not be feasible, it is critical for organizations to plan a gradual transition to modern solutions, ensuring their long-term security.

Ransomware installation via outdated software
The ransomware is still one of the most profitable tools in the arsenal of cybercriminals, and outdated software provides an easy point of entry. Once installed, the ransomware encrypts critical files, making them inaccessible until a ransom is paid. The consequences can be severe, often costing organizations millions of euros in recovery efforts, lost productivity, and damage to their reputation.
To address this threat, businesses must invest in endpoint security solutions that detect and prevent ransomware at the point of entry, significantly reducing the risk of a successful attack. These solutions use behavior-based detection to identify and neutralize malicious activity in real time. In addition, maintaining regular and secure backups of critical data allows for immediate system recovery. It is essential that backups are stored off-network or in secure environments cloud, so that they are protected from malicious users who attempt to exploit them for blackmail.

Electronic “fishing” (Phishing) gains ground when businesses use outdated applications
Phishing campaigns (Phishing) may be more successful in spreading malware, especially when they encounter outdated email programs. In such cases, they can bypass spam filters, making the messages appear legitimate. From there, unsuspecting employees are more likely to click on malicious links or download infected attachments, giving cybercriminals access to the company’s network.
Given that many small businesses cite phishing as their top cybersecurity threat, employee training is vital. Awareness programs should focus on:
-
In identifying phishing attempts,
-
In verifying the authenticity of Email,
-
And understanding the risk of clicking on unknown links or opening suspicious attachments.
Additionally, advanced email filtering solutions can block such messages, flag suspicious links, and detect malicious attachments before they reach employees. Even if credentials are compromised through a phishing attack, multi-factor authentication (MFA) adds an extra layer of security, making it much more difficult for hackers to gain access.
-
Undermining compliance and regulatory requirements
Beyond security risks, outdated software can also lead to non-compliance with regulatory frameworks such as HIPAA, the GDPR or CCAC. These regulations require the use of up-to-date and secure software to protect sensitive data. Non-compliance not only exposes businesses to stiff fines, but also damages their reputation and erodes customer trust. Cybercriminals are aware of the compliance challenges and often exploit these gaps to attack organizations with inadequate defenses.
Conducting regular software and compliance audits ensures that all systems meet the latest regulatory requirements. Managed service providers (MSP) can support businesses by managing updates, monitoring systems, and proactively addressing vulnerabilities. Maintaining detailed records of updates, software versions, audit schedules, and compliance measures demonstrates accountability and readiness during regulatory audits.
Prevention starts with organization
Protecting against the risks of outdated software is not just a matter of technology. There needs to be a security culture within the organization and proper prioritization. Management plays a key role: it decides where resources will be allocated and how the maintenance and security of systems will be organized.
Clear policies, cross-departmental collaboration, and regulatory compliance are essential. At the same time, modern solutions with artificial intelligence and machine learning are strengthening security, improving endpoint protection platforms and network monitoring tools. These technologies are able to detect threats and predict vulnerabilities in real time. At the same time, patch management based on cloud simplifies the update process, ensuring consistent protection for both remote and on-site teams.
With proper organization and utilization of technology, businesses can protect their data, enhance their credibility, and avoid the consequences of a serious breach.
