Mobile Application Penetration Testing

Securing a Mobile Banking App

Background

A financial institution with millions of users operating a nationwide mobile banking app.

Challenge

Secure against session hijacking, API abuse, and client-side data leakage.

Solution

Aegisbyte conducted full OWASP MAS assessment with Frida instrumentation, static and dynamic analysis, and API fuzzing across iOS and Android targets.

Results
  • Uncovered session token reuse across devices
  • Identified multiple API injection points
  • Discovered input validation flaws enabling account enumeration
  • Re-test validated all fixes within 30 days
“Working with Aegisbyte was a game-changer for our mobile banking security. Their thorough testing and expert guidance surfaced critical vulnerabilities we might have otherwise missed.”

External & Hybrid Network Penetration Testing

Hardening a Government Contractor Network

Background

A federal prime contractor expanding mission operations into a hybrid cloud architecture.

Challenge

Validate the attack surface of a hybrid network spanning on-premises enclaves and FedRAMP-moderate cloud workloads.

Solution

External pentest, internal emulation, and cloud configuration assessment using a blend of manual tradecraft and automated tooling aligned with NIST SP 800-115.

Results
  • Identified outdated firmware on edge infrastructure
  • Exposed weak and reused credentials in privileged accounts
  • Surfaced misconfigurations in the cloud landing zone
  • Hardened and retested infrastructure prior to ATO
“Aegisbyte found what our internal team missed. Their recommendations were practical, precise, and directly actionable against our ATO timeline.”

API Penetration Testing & Assurance

API Security for a Growing SaaS

Background

A fast-growing technology startup operating a high-volume API that drives its core product.

Challenge

Secure against injection, broken authentication, BOLA, and data exposure.

Solution

API pentest covering authentication flows, authorization logic, input validation, and business-logic abuse against OWASP API Top 10.

Results
  • Identified broken object-level authorization
  • Found weak password and token generation primitives
  • Discovered error-based data exposure pathways
  • Verified remediation via retest within two sprints
“Their API penetration test was thorough and insightful. The team identified real issues and educated our engineers on the underlying patterns.”

Advanced Adversary Emulation

APT Simulation Against a Manufacturer

Background

A manufacturing organization concerned about nation-state APT activity targeting intellectual property.

Challenge

Evaluate end-to-end defense against real-world APT tradecraft.

Solution

Full-scope APT simulation covering initial access, persistence, lateral movement, credential access, and exfiltration — mapped to MITRE ATT&CK.

Results
  • Exposed detection and response gaps across the kill chain
  • Identified strategic hardening opportunities
  • Delivered prioritized remediation roadmap
  • Validated improvements via follow-on purple team
“The APT simulation gave us deep visibility into our weaknesses. Their expertise in advanced threat emulation was invaluable to our security roadmap.”

OT / ICS Red Team Operation

OT / IoT Red Team for a Nuclear & Energy Operator

Background

An energy company operating both nuclear and industrial OT infrastructure across multiple sites.

Challenge

Assess the physical and cyber attack surface of OT, IoT, and protective systems under contested conditions.

Solution

Multi-site red team operation targeting OT/IoT — phishing, RF signal analysis, on-site access simulation, and protocol-level testing across Modbus and DNP3.

Results
  • Exposed supply-chain and vendor-access vulnerabilities
  • Identified Modbus network exposure across plant LANs
  • Surfaced weak physical access controls at operational sites
  • Delivered a comprehensive mitigation plan to leadership
“Aegisbyte brought unmatched realism to our OT security evaluation. Their comprehensive approach helped us understand our true posture under nation-state pressure.”
