What Scattered Spider and Tea App Breaches Tell Us About Security Gaps in 2025

What Scattered Spider and Tea App Breaches Tell Us About Security Gaps in 2025

2025 is proving one thing: the weakest link isn’t technology. It’s people—and processes.

Two recent, high-profile breaches—the Scattered Spider VMware ESXi attacks and the Tea app data leak—underscore how social engineering, misconfigurations, and identity gaps are driving breach velocity and blast radius.

Scattered Spider’s Takeover of VMware ESXi Environments

Scattered Spider (UNC3944, Scattered Swine) is known for abusing identity infrastructure and targeting hybrid IT environments. In their recent campaign, they escalated access to vCenter and ESXi hosts, effectively compromising virtualized infrastructure at scale.

Tactics Observed:

  • SIM Swapping Help Desk Personnel: Attackers impersonated staff, submitted social engineering requests to telecom providers, and took control of employee mobile numbers.

  • MFA Fatigue & Reset Abuse: Leveraged voice phishing and password reset portals to trigger push notification fatigue and reset credentials.

  • vCenter Admin Console Access: With valid credentials and MFA bypassed, attackers accessed vSphere, deployed persistent scripts, and disabled logging.

  • Ransomware Deployment: Final payloads included encryption of ESXi datastores and ransom notes via management dashboards.

Misconfiguration & Weaknesses Exploited:

  • Lack of MFA enforcement at the hypervisor layer

  • Help desk lacking callback verification protocols

  • Flat identity zones between cloud consoles and internal apps

  • No out-of-band alerting for suspicious activity

Mitigation Advice:

  • Enforce admin-only access with Just-in-Time provisioning

  • Implement segmented identity zones for infrastructure vs. SaaS

  • Use behavioral SIEM rules to flag suspicious interactions

The Tea App Photo Leak : Private Content made Public

Tea, a top-ranked free social app, silently uploaded users' private photos from their camera rolls to its backend without user awareness or proper encryption. A public exposure or breach resulted in thousands of personal images being scraped and leaked.

Root Cause:

  • Unsecured S3 Buckets or Backend Stores storing PII and media

  • Lack of data classification — personal photos were treated as non-sensitive

  • No user notification or opt-in for cloud sync

  • Weak access controls on mobile-to-cloud sync APIs

Why This Matters:

  • Most mobile apps use third-party cloud SDKs (Firebase, AWS Amplify) without security validation.

  • If you skip client-side encryption or fail to restrict object access at the API layer, photo dumps become trivial for attackers.

  • Insecure APIs can be enumerated via basic recon tools (Burp, OWASP ZAP).

Mitigation Advice:

  • Apply object-level IAM policies to cloud storage buckets

  • Encrypt media before transmission using AES-256 client-side

  • Use content-type DLP scans for publicly exposed media

  • Ensure consent-based sync with granular user settings

The Common Thread: Identity, Cloud Hygiene & Awareness

Both events bypassed traditional endpoint defenses. They exploited:

  • Over-privileged identities

  • Untrained help desk staff

  • Misconfiguration for cloud assets

  • Lack of visibility in virtual infrastructure
