Therefore, the interconnection between operational and IT networks creates an ideal environment for cybercriminals to exploit security flaws.
What are brute force attacks on Industrial Systems?
Brute-force attacks are login and password combinations . In the context of industrial systems, this technique seeks to exploit vulnerabilities in devices and control systems that often use default credentials or weak passwords . Therefore, increasing interconnectivity and industrial automation have made this type of attack an increasingly common threat
CISA the U.S. Cybersecurity and Infrastructure Security Agency) reported that attacks on industrial devices exposed to the internet are becoming increasingly common. Furthermore, attackers often use simple methods, such as brute-force attacks and default credentials, to compromise industrial control systems.
Industrial systems that rely on operational technologies (OT) and industrial control systems (ICS) can suffer serious consequences from a successful brute force attack. By gaining unauthorized access to these systems, cybercriminals can cause production disruptions, physical damage to equipment, and even compromise the security of critical infrastructure, such as power plants. In other words, the consequences of a successful attack can be devastating for businesses and society. Combating brute force attacks involves adopting proactive measures such as multi-factor authentication , implementing strict security policies , and regularly updating passwords . These approaches help prevent cybercriminals from gaining access to systems, mitigating the impact of potential intrusion attempts.
Concept of brute force attacks
Brute-force attacks are one of the oldest forms of cyberattacks, where the attacker repeatedly guesses password combinations until they find the correct one. Brute-force refers to the rudimentary but effective approach of testing every possible combination of credentials. This is achieved through automated that try millions of combinations per second , especially when the system uses or excessively weak passwords .
According to Unit 42's 2022 Incident Response Report , brute force credential attacks contributed to 20% of successful attacks during the period.
Furthermore, the use of default credentials in industrial systems represents a critical vulnerability, facilitating brute-force attacks. Many devices and control systems come with default passwords that, if left unchanged, allow cybercriminals to gain unauthorized access to networks and sensitive data. This highlights the importance of password management practices stronger passwords .
Therefore, the consequences of a successful attack in industrial environments can be devastating. Furthermore, disruption of critical processes, damage to equipment, and compromised data security are just some of the potential consequences.
Default credentials make life easier for cybercriminals. In other words, by using predefined passwords on devices and systems, companies open the door to brute-force attacks. To strengthen security, it's essential to implement temporary account lockouts after multiple failed login attempts and constantly monitor network activity.
How Brute Force Attacks Work
Brute-force attacks work by repeating login attempts using different username and password until the correct combination is found. Cybercriminals can use dictionaries of common passwords , leaked data from other platforms, and random sequences to speed up this process.
Furthermore, many of these industrial systems were not designed with the same robustness in terms of cybersecurity IT systems . This makes brute-force attacks effective, exploiting known vulnerabilities or weak credentials to gain control of critical systems.
Given this, a successful brute force attack could allow the attacker to shut down machines , manipulate production processes, and even cause catastrophic failures . Furthermore, it's important to mention the financial consequences for companies. According to IBM's Cost of a Data Breach 2024 report , the average global cost of a data breach in 2024 increased by 10% , reaching nearly $4.9 million .
To mitigate these attacks, it's essential to adopt basic security practices , such as locking accounts after multiple login attempts, multi-factor authentication , and strong, unique passwords . While seemingly simple, these measures significantly hinder cybercriminals' ability to carry out these types of attacks, increasing system security
Default credentials and their vulnerabilities
One of the biggest vulnerabilities in industrial systems is the use of default credentials . Furthermore, many ICS generic passwords and usernames , which are then used by companies. These credentials are easily accessible online or in factory manuals , making the system vulnerable to hacking.
The practice of maintaining default credentials administrators often underestimate the impact of these configurations, believing that network isolation or physical security would be sufficient to prevent attacks. However, increased connectivity and system integration have made these approaches largely obsolete .
For this reason, one of the main recommendations for mitigating brute force attacks is to immediately replace all credentials . Therefore, it's crucial to implement more secure passwords and authentication practices to avoid unnecessary vulnerabilities and keep operations secure.
Industrial Systems at Risk
