Automation has changed the way we work and live, making work more efficient and seamless. However, alongside its laudable benefits, there are emerging security risks associated with automation.

Automation can introduce new vulnerabilities, such as increased exposure to cyber attacks and dependence on third-party vendors. It is time to reconsider the other side of automation.

In this article, we discuss the potential security issues posed by automation and examine its implications for our interconnected world.

The Risks of Automation

Below are some of the possible risks of automation: 

• Increased attack surface: Automation expands the potential entry points for hackers, making it easier for them to gain access to sensitive systems and data. It involves integrating new tools, applications or systems into your existing stack. Sometimes, for effective integration, you need to login to several applications through the automation software. If that automation software is compromised, your login credentials and other sensitive information exchanged via the software will be exposed. To prevent this from happening, you need to 

• Vulnerabilities in software and hardware: Automation relies on complex software and hardware, which can contain vulnerabilities that hackers can exploit.

• Potential for machines to be used as weapons: Automation can be used to launch powerful attacks, such as distributed denial-of-service (DDoS) attacks, which can cripple entire organizations. The Mirai botnet attack in 2016 exploited IoT devices to launch a major DDoS attack.

• Dependence on third-party vendors and supply chains: Sharing sensitive data raises privacy concerns, and limited visibility into vendor operations complicates risk assessment. Automation often relies on third-party vendors and supply chains, which can introduce new security risks. Organizations have to rely on vendors' security practices, which may be weaker, increasing the risk of breaches. The SolarWinds attack involved hackers inserting malicious code into a routine software update for SolarWinds' Orion product, which was used to infiltrate numerous organizations. 

Automation Vulnerabilities in Various Industries

Automation vulnerabilities affect different industries in unique ways, including:

• Healthcare: Medical devices and automated systems can be hacked, compromising patient data and even putting lives at risk. WannaCry Ransomware Attack affected many organizations, including the UK's National Health Service (NHS). The malware encrypted data and demanded ransom payments. Many medical devices and systems were rendered inoperative, leading to the cancellation of thousands of appointments and operations.

• Finance: Trading systems and automated financial transactions can be manipulated, leading to financial losses and reputational damage. Hackers used malware to manipulate automated systems at Bangladesh Bank and managed to steal $81 million by sending fraudulent instructions to the Federal Reserve Bank of New York to transfer funds to accounts in the Philippines.

• Transportation: Self-driving cars and automated transportation systems can be hacked, potentially causing accidents and endangering lives. An example is the Tesla Automation Vulnerability, where a team of Chinese security researchers remotely hacked into a Tesla Model S from 12 miles away, gaining control of electronic features such as brakes, door locks, and the dashboard computer screen.

• Manufacturing: Industrial control systems and automated manufacturing processes can be breached, disrupting production and causing economic losses. The Stuxnet worm, for instance, targeted programmable logic controllers (PLCs) used in manufacturing. This caused significant disruption to Iran's nuclear enrichment facilities and highlighted the potential for automation vulnerabilities to impact industrial operations on a large scale.

Consequences of Automation Security Breaches

The consequences of automation security breaches can be severe, including:

• Robust System Failure: This occurs because automation heavily relies on interconnected systems, failure in one component could lead to failure in the entire system. 
• Compromised Supply Chain: Automated systems often rely on software and hardware from third-party vendors. A breach in a vendor's system can introduce malware or backdoors into automated processes, as seen in the SolarWinds attack.
• Malicious Code Injection: Attackers can inject malicious code into automated scripts and workflows. This can disrupt operations, exfiltrate data, or grant unauthorized access to critical systems.
• Rogue Automation Commands: Cyber attackers can take control of automation systems to issue rogue commands, potentially causing physical damage in industrial settings or corrupting data in software environments.
• Weak API Security: Automation often involves extensive use of APIs to connect different systems. Poorly secured APIs can be exploited to gain unauthorized access or manipulate automated workflows.
• Botnet Attacks: Automation tools can be hijacked to form botnets, which can then be used to launch large-scale attacks such as Distributed Denial of Service (DDoS) attacks, affecting the availability of automated services.
• Credential Theft and Abuse: Automation systems often use credentials to perform tasks. If these credentials are stolen or inadequately protected, attackers can exploit them to manipulate automated processes.

These threats highlight the need for comprehensive security measures tailored to the unique challenges posed by automated environments.

Securing Automated Processes

To secure automated process in your organization;

• Conduct regular security assessments and penetration testing to identify vulnerabilities.

• Adopt access controls and authentication to prevent unauthorized access to your automation software.

• Keep software and firmware up-to-date to patch vulnerabilities.

• Monitor systems for suspicious activity and respond quickly to security incidents.

Automation brings numerous benefits but it is important to note that it has potential vulnerabilities. We can reduce these threats and enjoy the advantages of automation without risking security. Regular assessments, updated software, and access controls are essential for ensuring automated processes are safe.
