Gaining Access in Penetration Testing Phase 3 Exploiting The System

November 29, 2025 Zubair Khan

Gaining access in penetration testing shows how a real attacker can enter a system. This stage reveals the strength or weakness of a target. Idealsols uses this phase to help companies understand real world entry points with clear evidence.


Meaning of Gaining Access in Penetration Testing

Gaining access, also known as exploiting. This phase focuses on entering a system after reconnaissance and scanning. It checks how a threat actor uses weak passwords, misconfigurations, faulty authentication, exposed services, and flawed code to break into networks, apps, cloud platforms, and websites. Pentesters collect exact proof to show the path taken to gain access so businesses can fix every weak point.


Why Gaining Access (Exploitation) Matters for Every Business?

Because real-world reports consistently show that skilled pentesters achieve initial access in the majority of controlled engagements when vulnerabilities exist. Credential abuse (including spraying, guessing, and cracking) remains the dominant initial access vector in actual breaches according to the Verizon DBIR 2025 .


Core Principles That Guide This Phase

  • Collect evidence of the entry point
  • Show the path used to enter the system
  • Confirm the weakness with technical clarity
  • Measure the time required for access
  • Avoid unnecessary disruption
  • Provide steps to prevent future entry

Idealsols performs these steps for businesses across Pakistan and worldwide.


Main Entry Methods Observed in Real Tests

Pentesters look at actions attackers usually attempt. The goal is to recreate real behaviour with safe processes.

  • Weak or repeated passwords found through password spraying
  • Password guessing during sessions
  • Password cracking after data retrieval
  • Misconfigured cloud services that reveal internal services
  • Broken authentication in web applications
  • Malicious file uploads with harmful code
  • Flawed access controls in APIs
  • Server side request actions in cloud and app targets
  • Hidden functions in mobile apps
  • Weak network protocols
  • Exposed external services in websites

Each method fits different systems based on the environment tested.


Gaining Access in Networks

Real-world reports consistently show that skilled pentesters achieve initial access in the majority of controlled engagements when vulnerabilities exist. Credential abuse (including spraying, guessing, and cracking) remains the dominant initial access vector in actual breaches according to the Verizon DBIR 2025 .

Idealsols uses controlled methods to find weak internal paths. The team reviews open services, shared folders, user accounts, and exposed ports to identify the weakest entry vector.


Gaining Access in Web Applications

Web applications commonly fail at authentication, access control, and input validation. Broken access control and injection flaws consistently rank among the top risks in the OWASP Top 10, while insecure file uploads and misconfigurations frequently enable remote code execution or web shell deployment. Testing focus on web applications increased 15 % year-over-year according to the Core Security 2024 report.

The Idealsols team analyses exposed forms, upload features, session handling, and backend calls. Every access path is documented with clear, reproducible proof.


Gaining Access in Cloud Systems

Cloud environments are increasingly targeted because of widespread misconfigurations and overly permissive identity roles. Testing focus on cloud infrastructure rose 20 % year-over-year (Core Security 2024), reflecting the rapid shift of critical assets to the cloud.

Idealsols checks access policies, identity roles, storage rules, admin panels, exposed buckets, and open cloud ports. The team maps the internal structure to show the exact steps an attacker would take.


Gaining Access in API Environments

APIs frequently suffer from broken object-level authorization (BOLA) – ranked the #1 risk in the OWASP API Security Top 10 – and Server-Side Request Forgery (SSRF).

Idealsols checks endpoints, roles, tokens, and backend communication. The goal is to find any point that lets someone act as another user.


Gaining Access in Mobile Apps

Mobile tests often review code storage, device controls, data caching, and unsafe calls. Pentesters inspect apps on three or more devices. They also analyse network communication to catch weak points. Weak checks, exposed sessions, and unsafe data storage lead to direct entry.

Idealsols maps each mobile endpoint and collects proof of unsafe behaviour.


How Idealsols Documents Gained Access

  • Records every attempted entry
  • Shows exact steps taken
  • Notes time required for entry
  • Combines screenshots with clean explanations
  • Provides simple action steps for prevention
  • Shares a clear list of future risks
  • Creates a final document showing impact

Prevention Steps After Gaining Access

  • Stronger access rules
  • Advanced password control
  • Multi factor checks
  • Removal of unused services
  • Safer cloud policies
  • Cleaned user roles
  • Updated certificates
  • Better session control
  • Safer upload features
  • Code review for backend logic
  • Clear staff training

Idealsols guides each company with direct and simple actions.


Frequently Asked Questions

What does gaining access mean in penetration testing?

It refers to the moment a pentester enters a target system and confirms the first successful point of entry.

Why do companies need gaining access tests?

It shows the real danger by proving how attackers can enter systems through weak controls.

How does Idealsols perform gaining access testing?

The team reviews network, cloud, app, API, and mobile systems to find real entry vectors with clean evidence.

Can gaining access reveal hidden weaknesses?

Yes, it often uncovers unknown risk points that routine scans miss.

What is the role of passwords in gaining access?

Weak passwords cause many successful entries including spraying and guessing attempts.

How long does gaining access take in real tests?

Reports show entry can occur within one hour in some cases.

Can Idealsols help if a company has failed past audits?

Yes, the team builds a full access risk map based on your environment.

Does gaining access apply to small businesses?

Yes, small systems face the same risk and often more because of limited controls.

Is gaining access used in reports and audits?

Yes, each access point forms part of the final security document.

Can this phase expose unsafe user roles?

Yes, pentesters can identify incorrect permissions through direct entry paths.

Does gaining access affect compliance?

Yes, correct handling of access weaknesses helps pass regulatory checks.

What makes Idealsols better for this phase?

The team uses multi angle methods, real world numbers, and clear explanations.

Can gaining access support long term defence?

Yes, once weaknesses are known you can build stronger security plans.
