Top 15 Cloud Security Threats 2026

The binary beaconed out to UNC4899-controlled domains and served as the backdoor that gave the threat actors access to the victim’s workstation, effectively granting them a foothold into the corporate network. Instead, threat actors (a polite term that encompasses both criminal gangs and state-sponsored agents, notably from North Korea) are targeting unpatched vulnerabilities in third-party code. The jury is still out on whether most businesses get any measurable benefit from implementing artificial intelligence in their organizations, and the debate is likely to get more contentious over time. https://www.ournhs.info/finding-similarities-between-and-life-5/ Google’s latest threat report warns that third-party tools are now prime targets for attackers – and businesses have only days to prepare defenses. Our experts help ensure cloud and platform security, with broader visibility to cloud infrastructure, both now and into the ever-evolving future. The KuppingerCole data security platforms report offers guidance and recommendations to find sensitive data protection and governance products that best meet clients’ needs.

For example, it may remind a user that the genAI app they are about to use is not approved for sensitive data and ask if they would like to use it anyway. Source code, regulated data (such as personal, financial, or healthcare data), intellectual property, and passwords and keys (typically leaked in source code) all represent a significant percentage of the violations. Generative AI app use has continued to increase throughout 2024 in terms of three key metrics.

What makes this trend particularly notable is that it is occurring despite increased controls and governance around managed genAI applications. Much like the early days of SaaS and cloud platforms, many workers began experimenting with AI apps on their own, usually by signing in with personal accounts long before IT or security teams deploy company-approved genAI tools among their workforce. Concurrently, the operational introduction of agentic AI systems, which execute complex, autonomous actions across internal and external resources, creates a vast, new attack surface that necessitates a fundamental re-evaluation of security perimeters and trust models. This accelerated adoption is frequently driven by shadow AI—employee use of unmanaged services and personal accounts—resulting in the leakage of highly sensitive material, including source code, regulated data, and intellectual property. Furthermore, it highlights the growing number of data policy violations, where sensitive information is increasingly being leaked through unauthorized cloud services, personal applications, and genAI platforms.

• The swift adoption of cloud services has increased the attack surface for cybercriminals, placing enterprises at risk from various cloud security threats.
• While the cloud has many benefits for businesses, it also has some Cloud Security Threats and its issues.
• This shift enabled them to move from reactive alert handling to proactive exposure management, turning cloud security into a strategic advantage.
• The actual shift of responsibility depends on the cloud service model(s) used, leading to a paradigm shift for agencies in relation to security monitoring and logging.
• This lack of visibility and control over unauthorized cloud services means that security and IT teams cannot effectively enforce security policies or protect sensitive data.

Permanent Data Loss

Ultimately, a key goal is to empower organizations to leverage their purchasing power to procure secure software products, turning the “secure by design” principle into “secure by demand,” CISA Director Jen Easterly said in a statement. The report lists a total of 11 major cloud-computing threats, describes and analyzes them, identifies their business impacts, offers key takeaways, provides real-world examples and more. And get the latest on the Royal ransomware gang, the CIS Benchmarks and TikTok’s legal troubles! The Cloud Security Alliance has released its list of top cloud threats for 2024. The supply chain continues to be a significant area of risk, and we’ve observed threat actors using trusted cloud services to host decoy files and payloads.

Best Practices from Industry for Implementing a Zero Trust Architecture

• AI also influenced cloud-focused threat actor activity in 2025, not by introducing fundamentally new attack techniques, but by expanding cloud attack surfaces and enabling threat actor workflows in select cases.
• The accidental exposure of private or sensitive data left unsecured by the API is the business consequence that is most frequently reported.
• Shadow IT use can result in network bandwidth issues, compliance risks and security threats, such as data loss and data breaches.
• Challenges, best practices, and key components for helping protect cloud-hosted data from misconfigurations, insider threats, and breach propagation across hybrid environments.

As a result, sensitive https://babyandmomtimes.com/baby-care-for-first-time-parents/14-best-apps-for-brand-new-moms/ data is at risk of exposure – as demonstrated by a massive number of cloud data breaches. This means that a successful Denial of Service (DoS) attack against cloud infrastructure is likely to have a major impact on a number of different companies. This problem exacerbates the impact of phishing attacks and data breaches since it enables a single stolen password to be used on multiple different accounts. Behavior-driven analytics enable Exabeam to go beyond static rules and signatures, identifying anomalous activity that indicates credential misuse, insider threats, or lateral movement across the network. In 2019, the global enterprise software company SAP experienced a data governance failure when a breach exposed the sensitive data of its cloud customers.

About ExtraHop ExtraHop is on a mission to arm security teams to confront active threats and stop breaches. The biggest threats to cloud security include data leaks, token hijacking, Insider threats, DDoS, and ransomware attacks. SentinelOne provides a unified security approach by managing risk and reducing the attack surface. They consist of data breaches, account hijacking, ransomware, and supply chain attacks that occur in cloud environments. Instead of using siloed tools, organizations get unified protection against modern cloud threats, ranging from data breaches to misconfigurations. SentinelOne’s approach helps companies reduce risk, prevent alert fatigue, and keep cloud operations running smoothly.

SaaS genAI use is rapidly increasing

Although vulnerability disclosures varied by platform and year, the resulting business impacts were largely unchanged. The most common outcomes remained concentrated in cross-site scripting, unauthorized access, and information disclosure, reinforcing that cloud risk continues to be driven primarily by application- and identity-layer weaknesses rather than direct compromise of core cloud infrastructure. Collectively, these significant security vulnerabilities in widely-used cloud management platforms exposed organizations to a variety of impact outcomes such as privilege escalation, code execution, and data disclosure risks. A spoofing vulnerability was disclosed impacting Nebula, while a vulnerability with potential implications for sensitive data exposure was identified in the HubSpot Android application.
