Cloud adoption is driving business innovation, but it also increases the risk of cyberattacks. Almost 83% of organizations have faced a cloud breach, with each incident costing about $4.88 million. The flexibility that helps businesses grow also puts essential assets at risk.

As workloads shift between platforms, mistakes in setup, weak identity controls, and insecure APIs create new risks. Since 82% of breaches involve cloud-stored data, having clear visibility and consistent controls is now just as important as old perimeter defenses.

This guide examines the top cloud security threats of 2025 and their impact on modern infrastructure.

Key Takeaways

• Misconfigurations cause 99% of cloud security failures, and they are often due to human error and inconsistent controls.
• The average breach cost has climbed to about $4.88 million, with multi-cloud breaches even higher.
• 82% of breaches involve cloud-stored data, highlighting the importance of visibility and encryption.
• Zero Trust and MFA can cut breaches by up to 80%, reducing impact and speeding recovery.
• Ransomware cloud attacks rose 126% year over year, with average recovery costs exceeding $5 million.
• Supply chain attacks take an average of 267 days to detect and contain, posing long-term exposure risks.
• Organizations face 1,876 cyberattacks weekly, led by ransomware and API exploits.

The Cloud Security Threat Landscape in 2025

Cloud computing continues to power digital transformation, but it also reshapes the risk landscape. Global cloud spending is expected to reach more than $723.4 billion as organizations move toward hybrid and multi-cloud setups.

This fast growth encourages innovation but also gives attackers more ways to get in, so organizations need better visibility and control.

Current State and Statistics

Cloud security threat statistics

Cloud breaches are on the rise, indicating that managing risks is becoming harder as cloud use grows. There are now more than 1,870 cyberattacks each week on average, and ransomware attacks have increased as more organizations move to the cloud.

Detection remains a persistent challenge. Many organizations take 283 days to identify a compromise, giving attackers time to move freely through systems.

The financial toll is rising as well, with average breach costs approaching $4.4 million and even higher in multi-cloud settings. Most breaches involve cloud-stored data and are linked to:

  • Misconfigurations and weak access control
  • Inconsistent monitoring and visibility gaps
  • Poor separation between cloud environments

Major incidents like the Change Healthcare breach and the National Public Data exposure show how quickly mistakes can lead to huge data leaks. These cases highlight that a lack of visibility remains a major weakness in cloud security.

Why Cloud Environments Are Targeted

Cloud environments are prime targets because they hold valuable data in complex, interconnected systems. Roughly 9% of publicly cloud storage contains sensitive data, and nearly all of it is highly confidential.

Many exposures result from misconfigurations, which cause about 23% of cloud security issues and are often due to human error. Attackers swiftly take advantage of blind spots that appear when businesses spread across several cloud platforms.“

Several factors make cloud infrastructures especially appealing:

  • The expansion of remote access has increased opportunities for attacks.  
  • AI-driven threats have automated credential theft and scanning.
  • Limited visibility across platforms allows intrusions to go unnoticed.

The effects go beyond downtime. About 86% of companies experience operational disruptions, 70% of customers stop buying from affected brands, and many organizations also face compliance fines.

In response, organizations are boosting security budgets to strengthen identity management, visibility, and incident response.

Top 10 Cloud Security Threats for 2025

Top 10 cloud security threats overview

Cloud environments now support most digital operations, but as they get more complex, attackers find more ways in.

Weak configurations, exposed interfaces, and unmanaged access controls continue to drive most cloud incidents. Even small mistakes can result in significant security flaws as companies grow across several platforms.

Below are the top 10 biggest cloud security threats for 2025:

1. Misconfigurations and Inadequate Change Control

Misconfiguration remains the leading cause of cloud security breaches, often exposing sensitive data or enabling unauthorized access. Almost all failures (99%) are due to customer misconfiguration, highlighting the importance of adhering to strict configuration practices. 

Cloud security misconfiguration checklist

In 2025, 74% of organizations had publicly exposed storage containing sensitive data, making this one of the most common and dangerous mistakes. High-profile breaches like Toyota’s 2023 exposure of 260,000 customer records and Capital One’s 100 million–record leak reveal how small errors can have major consequences.

To prevent these incidents, companies should use automated tools to scan configurations, deploy CSPM solutions, and regularly check for changes that could weaken security.

2. Identity and Access Management (IAM) Failures

Weak identity controls remain one of the most exploited vulnerabilities in the cloud. About 35% of incidents involve the abuse of legitimate accounts, and 80% of breaches stem from compromised privileged credentials

Once attackers gain valid access, they can move through systems unnoticed and extract sensitive data. Common weaknesses include:

  • Weak passwords and missing MFA
  • Excessive permissions or privilege creep
  • Orphaned accounts left active
  • Poor monitoring of admin and service accounts

These gaps make it much easier for attackers to impersonate trusted users and bypass standard defenses. Regular IAM checks, strong MFA, and careful review of user privileges are key to fixing these issues.

3. Insecure APIs and Interfaces

APIs connect core cloud services, making them prime targets. About 92% of organizations experienced an API-related security incident, and most lacked complete visibility into what their APIs exposed. Even one breached API can expose multiple systems.

Here are the common API security vulnerabilities:

  • Weak or missing authentication controls
  • No rate limiting or throttling
  • Poor input validation
  • Broken object-level authorization
  • Excessive data exposure
  • Lack of encryption in transit

To protect APIs, organizations need to identify all their APIs, test them regularly, and monitor their use to catch problems before they escalate into major breaches.

4. Data Breaches and Exfiltration

Data breaches continue to be the most damaging consequence of cloud insecurity. An alarming 82% of breaches now involve data stored in the cloud, and more than half of these incidents expose personal or financial information.

Each compromised record costs $165, which has a significant financial impact. Furthermore, 60% of malware downloads come from cloud apps, indicating that attackers are increasingly taking advantage of reliable platforms.

Most breaches can be traced back to recurring vulnerabilities that attackers exploit.

VectorTypical Weakness
Misconfigured storagePublicly accessible buckets or blobs
Compromised credentialsStolen or reused logins
Insecure APIsWeak authentication or authorization
Insider activityMisuse or accidental disclosure
Weak encryptionUnprotected data in transit or at rest

Major breaches in recent years show the cost of simple mistakes:

  • Change Healthcare exposed 192.7 million patient records.
  • Dell lost 49 million customer records.
  • Roblox developer data was stolen in 2025.

Using strong encryption, data loss prevention tools, and ongoing monitoring are the best ways to prevent data theft. These steps help organizations find and stop breaches early.

5. Insufficient Identity, Credential, and Access Management

Cloud account hijacking has become one of the fastest-rising attack vectors in cloud environments. In 2023, account threats surged sixteenfold, and compromised credentials were responsible for 16% of breaches.

Once attackers gain access, they often remain undetected for months, quietly taking control of resources or exfiltrating sensitive data. Here are their frequent attack methods:

  • Phishing campaigns target the majority of organizations.
  • Credential stuffing and password spraying.
  • Session hijacking and token theft.
  • MFA bypass techniques.

When these attacks succeed, they often result in privilege misuse, account theft, and service disruptions that disrupt business operations.

ImpactResult
Account takeoverFull control of cloud assets
Privilege abuseData theft and unauthorized access
Service disruptionDowntime and financial loss

6. Insider Threats (Malicious and Unintentional)

Insider activity is often an overlooked risk in cloud security. Nearly 28% of cloud breaches involve internal users, whether through negligence, compromised accounts, or deliberate misconduct. 

Insider risks remain a serious worry for 74% of firms. The substantial financial consequences are demonstrated by the average cost of a malicious insider occurrence, which is about $4.92 million.

These can be grouped into three types:

  • Malicious: Intentional data theft or system sabotage
  • Negligent: Accidental exposure or poor security hygiene
  • Compromised: Legitimate accounts hijacked by external attackers

Privileged access monitoring, data loss prevention tools, and user behavior analytics can help organizations detect these problems before they become critical.

7. Ransomware and Malware Targeting Cloud

Ransomware remains a dangerous and rapidly evolving threat in the cloud. In early 2025, attack activity surged by 126% YoY. The damage is severe, with destructive ransomware cloud attacks now costing organizations an average of $5.08 million.

Modern campaigns increasingly target cloud backups and combine encryption with data theft. Some variants even use AI‑driven evasion techniques to bypass defenses and accelerate propagation.

Ransomware typically spreads through stolen credentials, moves through systems, and encrypts data before demanding payment. Good defenses include endpoint detection tools, watching user behavior, and keeping backups that attackers cannot change or remove.

8. Supply Chain and Third-Party Risks

Supply chain and third‑party compromises have become a major source of risk in the cloud ecosystem. They now rank as the second-most-frequent and second-most-expensive attack vector facing organizations today.

These incidents also take the longest to resolve among major attack vectors. On average, organizations required 196 days to identify (MTTI) and 71 days to contain (MTTC) such breaches, for a combined 267 days before full resolution.

Key vulnerabilities include:

  • Compromised software dependencies and open-source components
  • Third-party cloud integrations and managed service provider breaches
  • Stolen or misused vendor access credentials

One well-known example is the MOVEit exploit, which affected about 66.4 million users and caused damages of more than $12.15 billion. It demonstrated how a single concession may affect entire industries.

To protect against these risks, organizations should track their software components, scan for risky dependencies, and regularly check their vendors for security issues. These steps help find problems before attackers do.

9. Advanced Persistent Threats (APTs)

Advanced Persistent Threats (APTs) are long‑term, highly targeted campaigns typically run by state‑sponsored or organized crime groups. In cloud environments, APTs pose a serious risk. They have been detected in about 25% of organizations and account for 43% of the most critical security breaches.

APTs are designed to infiltrate quietly and persist over time, focusing on high‑value assets. They rely on custom malware, “living‑off‑the‑land” techniques, and multi‑stage operations that can unfold over weeks or months.

Typical characteristics of APT campaigns:

  • Multiple stages progression: initial access → privilege escalation → lateral movement → data exfiltration
  • Custom tools and malware designed to evade detection
  • Patient reconnaissance and advanced evasion strategies

Organizations should use multiple layers of defense, such as threat intelligence, analytics, and ongoing monitoring, to catch problems early.

10. AI-Powered and Deepfake Attacks

As artificial intelligence becomes part of everyday business, attackers are using it to launch faster and more convincing attacks. More than 75% of organizations struggle to keep up with AI-powered threats, and almost 90% of security leaders believe AI-based defenses are now essential.

These threats blur the line between real and fabricated communication, making detection increasingly difficult.

Deepfake impersonationSynthetic voice and videoVoice and identity authentication
Adaptive malwareSelf-evolving attack codeBehavioral analytics and anomaly detection

Understanding Breach Costs and Business Impact

A cloud breach causes more than just data loss. It can lead to financial strain, downtime, and damage to reputation, which can slow digital progress for years. Knowing where costs add up helps security leaders show why prevention and automation matter.

Financial Impact Breakdown

Data breaches create costs that ripple across the entire organization. These expenses typically fall into five core areas: 

  • Detection
  • Disruption
  • Recovery
  • Compliance
  • Customer impact

Lost business and downtime are usually the biggest costs after a breach, often accounting for more than half of total expenses.

Cloud breach cost breakdown by threat type
Cost ComponentDescriptionBusiness Effect
Detection and escalationIncident analysis, forensics, and containmentDelays increase total breach cost significantly
Business disruptionDowntime, lost productivity, and system outagesDirect revenue and reputation losses
Post-breach recoveryData restoration, infrastructure rebuildsSlower return to normal operations
Compliance and legalRegulatory fines, settlements, and lawsuitsLong-term financial liability
Customer turnoverLoss of trust and market confidenceHardest impact to recover from

Organizations that use AI for detection and automated response often spend less on breaches. Finding and stopping attacks faster means less downtime, fewer regulatory problems, and real savings.

Operational and Reputational Impact

A cloud breach can cause far more disruption than just financial recovery. Approximately three out of four organizations have downtime, and it frequently takes more than 100 days to recover.

Key impacts include:

  • Service degradation and extended outages
  • Decreased employee productivity
  • Erosion of customer trust and brand reputation
  • Increased regulatory and audit scrutiny

Reputation recovery takes considerably longer than system restoration. Many organizations face sustained customer churn and market hesitation long after operations resume. 

Recovery DurationShare of Organizations
More than 150 days26%
126–150 days24%
101–125 days26%
76–100 days17%

In regulated industries, required notifications, extra oversight, and compliance fines add more pressure. Being open, communicating clearly during a crisis, and taking responsibility after an incident help restore trust and stability over time.

Cloud Security Mitigation Strategies and Best Practices

To counter new threats, cloud environment security calls for a flexible, multi-layered strategy. Multi-factor authentication (MFA), a zero-trust model, API security, and AI detection are important tactics that improve data protection and guarantee compliance.

Foundational Security Controls

A secure cloud environment starts with strong basics that protect identities, data, and systems. By focusing on these core security controls, organizations can lower the chances and impact of breaches.

These key practices are the basics of a strong cloud security plan. Each one addresses important risks and helps the organization stay strong.

1. Multi-Factor Authentication (MFA): Adds an extra credential layer; modern methods cut breaches by up to 80%.

2. Zero Trust Architecture: Adopts a “never trust, always verify” approach that prevents lateral attacker movement.

3. Least Privilege Access (PoLP): Limits permissions to essentials; reviews and just‑in‑time access reduce risks.

4. Data Encryption: Secures data in transit and at rest with strong key management.

5. Cloud Security Posture Management (CSPM): Continuously scans, detects misconfigurations, and automates remediation for compliance.

6. Infrastructure as Code (IaC): Automates deployments with version control; enforces compliance via policy‑as‑code.

7. Logging and Monitoring: Centralized logs and AI analytics enhance detection and threat hunting.

8. Incident Response Planning: Defines roles and recovery steps; testing and backups minimize downtime.
