In our previous blog post, “The Human Factor: Top 7 Human-Generated Vulnerabilities in 2025 and How to Secure Them,” we explored the critical role that human actions play in exposing cloud environments to risks. From phishing susceptibility to unauthorized credential sharing, these vulnerabilities underscore a persistent challenge: even the most advanced cloud infrastructures can be undermined by simple oversights or lapses in judgment. Building on that foundation, this executive guide shifts focus to proactive mitigation strategies, emphasizing training programs and automation tools. By implementing role-based access controls (RBAC) and AI-driven monitoring, organizations can achieve immediate threat reduction, minimizing the window for human errors to escalate into breaches. Below, we revisit the top seven vulnerabilities with real-world examples from 2024 and 2025, then outline actionable steps for training and automation.

Revisiting the Top 7 Human-Generated Vulnerabilities with Recent Examples

Human errors remain a dominant factor in cloud security incidents, accounting for up to 88% of data breaches in recent years. 4 Here, we highlight each vulnerability with examples drawn from 2024 and 2025 incidents, illustrating their ongoing relevance.

1. Phishing Susceptibility
   Phishing exploits human trust, often leading to credential theft in cloud systems. In 2024, phishing was the most common attack vector, contributing to 73% of cloud security breaches and a 75% increase in cloud intrusions. A prominent example is the Change Healthcare breach, where attackers used phishing to gain initial access, disrupting services and exposing sensitive data. In 2025, phishing continued to dominate, with 33% of cloud-related incidents starting this way; an early-year attack on a major financial firm involved AI-crafted emails that bypassed filters, leading to unauthorized cloud storage access. 
2. Weak or Default Passwords
   Simple or unchanged passwords enable brute-force attacks on cloud accounts. In 2024, weak credentials were behind nearly half of all cloud-based attacks, with 81% of hacking-related breaches stemming from password issues. The Snowflake data breach exemplified this, where customers’ use of single-factor authentication and default credentials allowed attackers to compromise hundreds of organizations. In 2025, similar issues persisted, as seen in the Microsoft password-spraying incident reported early in the year, where weak passwords facilitated access to cloud resources. 
3. Social Engineering (Beyond Phishing)
   Tactics like vishing or pretexting manipulate individuals to divulge information. In 2024, business email compromise (BEC) attacks, a form of social engineering, caused $2.77 billion in losses globally. An example is the MGM Resorts incident extension into 2024 investigations, where attackers used voice impersonation to extract credentials for cloud access. In 2025, over one-third of social engineering incidents involved non-phishing methods like fake software updates; a notable case involved hackers impersonating IT staff via phone and text to breach a healthcare provider’s cloud environment. 
4. Misconfigured Security Controls
   Oversights in settings, such as open storage buckets, expose data. In 2024, misconfigurations accounted for 23% of cloud security incidents, leading to 27% of companies experiencing public cloud breaches. The Mercedes-Benz breach occurred when an employee exposed a GitHub token in a public repository, granting access to cloud data. In 2025, misconfigurations continued to plague organizations, with the Wealthsimple incident exposing client data due to improperly configured cloud permissions. 
5. Insider Threats (Negligent or Malicious)
   Trusted individuals can cause harm through negligence or intent. In 2024, 48% of organizations reported an increase in insider threats, with average costs reaching $17.4 million annually by 2025 projections. A 2024 example is the Codecov supply chain attack aftermath, where an insider-modified script led to cloud credential leaks. In 2025, insider threats amplified, as evidenced by a reported case at a tech firm where a negligent employee emailed sensitive cloud access keys, resulting in data exfiltration.
6. Insufficient Security Awareness Training
   Without proper education, employees amplify other risks. In 2024, over 60% of organizations faced public cloud incidents partly due to poor training, contributing to a $1.76 million increase in breach costs from skills gaps. The 2024 CrowdStrike outage highlighted this, where lack of training on update processes exacerbated cloud disruptions. In 2025, insufficient training was linked to 77% of organizations citing it as a key obstacle; a financial services breach early in the year stemmed from untrained staff mishandling cloud configurations. 
7. Unauthorized Credential Sharing
   Sharing logins creates untracked access points. In 2024, stolen credentials were used in 88% of web application attacks, often from shared accounts. The Oracle Cloud breach in early 2025 involved hackers using shared stolen credentials to access servers. In 2024, similar sharing contributed to the PowerSchool incident, where unauthorized access via shared credentials exposed educational data.  

These examples demonstrate that human-generated vulnerabilities are not abstract—they manifest in costly, high-profile incidents that disrupt operations and erode trust.

The Role of Training in Mitigation

Effective training is essential for empowering employees to recognize and avoid these pitfalls. Programs should be continuous, role-specific, and measurable, incorporating simulations and metrics like phishing click rates. One example of a key training subject is “Identifying and Reporting Social Engineering Tactics,” which covers recognizing vishing calls, verifying unsolicited requests, and using secure communication protocols. By focusing on such targeted subjects, organizations can reduce susceptibility by up to 300%, as noted in prior analyses.

Leveraging Automation for Immediate Threat Reduction

Automation complements training by enforcing consistency and detecting anomalies in real time. Implementing role-based access controls (RBAC) ensures users have only the permissions necessary for their roles, limiting damage from compromised accounts. Pair this with AI-driven monitoring, which analyzes user behavior for deviations—such as unusual login patterns or bulk data access—and triggers alerts or automated lockdowns. Tools like AWS Config for configuration checks or UEBA systems can reduce response times from days to minutes, providing an immediate layer of defense against human errors.

Conclusion

Mitigating human errors in cloud environments requires a balanced approach of targeted training and robust automation, including RBAC and AI-driven monitoring.
