The original OSCE was retired and replaced by OSCE3, which requires passing three separate advanced practical exams: OSWE (web exploitation, WEB-300), OSEP (evasion and AD attacks, PEN-300), and OSED (Windows exploit development, EXP-301). Each exam runs approximately 48 hours plus 24 hours for report submission. Course+Cert Bundle pricing starts at $1,749 per course; Learn One subscription is $2,749/year. OSCE3 is awarded automatically at no additional cost.

Sample OSCE3 Practice Questions

Try these sample questions to test your OSCE3 exam readiness. Each question includes a detailed explanation. Start the interactive quiz above for the full 100+ question experience with AI tutoring.

1In the OSCE3 certification path, which three OffSec certifications must be earned to receive the OSCE3 designation?
A.OSCP, OSWE, OSEP
B.OSWE, OSEP, OSED
C.OSCP, OSED, OSEE
D.OSWE, OSEE, OSEP
Explanation: OSCE3 is automatically awarded upon earning OSWE (WEB-300), OSEP (PEN-300), and OSED (EXP-301). There is no separate OSCE3 exam. OSCP is a prerequisite-level cert, and OSEE is the elite exploit development cert, neither of which are OSCE3 components.
2During an OSWE (WEB-300) exam, you discover a PHP application using unserialize() on user-controlled input. Which attack class is most directly applicable?
A.SQL injection via prepared statement bypass
B.PHP object injection leading to remote code execution
C.XML External Entity (XXE) injection
D.Server-Side Template Injection (SSTI)
Explanation: When PHP's unserialize() processes attacker-controlled data, it can instantiate arbitrary objects, triggering magic methods (__wakeup, __destruct) in existing classes. This PHP object injection can chain gadgets to achieve RCE. XXE targets XML parsers, SSTI targets template engines, and SQL injection targets database queries.
3In the PEN-300 (OSEP) course, what is the primary purpose of using Process Hollowing?
A.To escalate privileges from a standard user to SYSTEM
B.To inject malicious code into a legitimate process to evade detection
C.To extract credentials from LSASS memory
D.To perform lateral movement via WMI
Explanation: Process Hollowing creates a suspended instance of a legitimate process (e.g., svchost.exe), unmaps its original code, and replaces it with malicious code before resuming execution. This technique evades security tools that trust the process by its name and path. Privilege escalation, credential extraction, and lateral movement are separate attack techniques.
4When developing a Windows exploit for the OSED (EXP-301) exam, what does DEP (Data Execution Prevention) prevent?
A.Writing to memory regions marked as executable
B.Executing code in memory regions marked as non-executable
C.Loading DLLs from untrusted paths
D.Stack cookie verification during function return
Explanation: DEP marks data regions (stack, heap) as non-executable, preventing direct shellcode execution from those locations. Attackers must use techniques like ROP (Return-Oriented Programming) to bypass DEP. DLL loading restrictions relate to SafeDLL search, and stack cookies relate to /GS buffer overflow protection.
5In a white-box web application assessment for OSWE, you find a Java application using Runtime.getRuntime().exec() with user input concatenated into the command string. What is the most effective exploitation approach?
A.Use OS command injection with semicolons or pipes to chain commands
B.Inject LDAP query syntax to bypass authentication
C.Exploit a race condition in the file upload handler
D.Perform SSRF to access internal metadata endpoints
Explanation: When user input is directly concatenated into a system command string passed to Runtime.exec(), OS command injection via metacharacters (;, |, &&, ||, backticks) allows execution of arbitrary commands. LDAP injection targets directory queries, race conditions exploit timing, and SSRF targets internal services.
6What is the primary purpose of ASLR (Address Space Layout Randomization) in the context of Windows exploit development?
A.To encrypt shellcode payloads in memory
B.To randomize the base addresses of loaded modules and memory regions
C.To prevent buffer overflows by checking stack boundaries
D.To block unsigned code from executing in kernel mode
Explanation: ASLR randomizes the base addresses of executables, DLLs, stack, and heap at each process startup, making it difficult for attackers to predict memory addresses for reliable exploitation. Exploit developers bypass ASLR by finding non-ASLR modules or using information disclosure vulnerabilities to leak addresses.
7During OSEP-level Active Directory exploitation, you compromise a user account with unconstrained delegation enabled. What can you do with this access?
A.Only authenticate to services on the delegated server
B.Capture and reuse TGTs from users who authenticate to the compromised server
C.Directly modify the domain's Group Policy Objects
D.Reset passwords for all domain users without credentials
Explanation: Unconstrained delegation allows a server to impersonate any user who authenticates to it by storing their TGT (Ticket-Granting Ticket). An attacker who compromises such a server can extract cached TGTs and use them to authenticate as those users to any service in the domain, potentially including Domain Admins.
8In EXP-301 (OSED), what is the purpose of a ROP (Return-Oriented Programming) chain?
A.To bypass network firewalls during exploitation
B.To execute attacker-controlled operations using existing code snippets (gadgets) to bypass DEP
C.To encrypt the exploit payload to avoid signature detection
D.To brute-force ASLR randomization by spraying the heap
Explanation: ROP chains string together small sequences of existing executable code (gadgets) ending in RET instructions to perform operations like calling VirtualProtect() or VirtualAlloc() to mark memory as executable. This bypasses DEP since the gadgets reside in already-executable code regions.
9In a WEB-300 scenario, you find a .NET application using ViewState without MAC validation. What attack is most directly enabled?
A.Cross-site scripting via reflected ViewState parameters
B.ViewState deserialization attack to achieve remote code execution
C.SQL injection through ViewState-encoded database queries
D.CSRF by forging ViewState tokens
Explanation: When ASP.NET ViewState lacks MAC (Message Authentication Code) validation, an attacker can craft malicious serialized objects in the ViewState parameter. The server deserializes this data, potentially triggering gadget chains (e.g., via ysoserial.net) that execute arbitrary commands.
10When performing AMSI (Antimalware Scan Interface) bypass during an OSEP engagement, what does patching amsi.dll's AmsiScanBuffer function accomplish?
A.It disables Windows Defender's real-time file scanning
B.It prevents PowerShell and .NET scripts from being scanned before execution
C.It removes all AV signatures from the local database
D.It disables Windows Event Log recording
Explanation: AMSI provides a standardized interface for applications (PowerShell, .NET, VBScript, JScript) to submit content for AV scanning before execution. Patching AmsiScanBuffer to return a clean result (AMSI_RESULT_CLEAN) prevents in-memory script content from being detected, allowing malicious scripts to execute unscanned.

Frequently Asked Questions

What happened to the original OSCE certification?

The original OSCE was retired and replaced by OSCE3. OSCE3 requires passing three separate advanced exams (OSWE, OSEP, OSED) instead of a single exam, providing deeper expertise across web exploitation, evasion, and exploit development.

How much does OSCE3 cost in total?

At minimum $5,247 for three Course+Cert Bundles ($1,749 each). The Learn One subscription ($2,749/year) includes one course with 2 exam attempts. Learn Unlimited is approximately $6,099/year with unlimited attempts. Always verify current pricing at offsec.com.

How long are the OSCE3 component exams?

Each component exam (OSWE, OSEP, OSED) provides approximately 47 hours 45 minutes of exam time, followed by a 24-hour window to write and submit a professional penetration testing report.

Do OSCE3 certifications expire?

As of 2025, OSWE, OSEP, and OSED do not expire. OffSec's expiring model (the '+' designation) currently applies to OSCP+ only. Verify current policies in OffSec's renewal documentation.

What order should I take the three OSCE3 exams?

Most candidates start with OSEP (PEN-300) if coming from OSCP, as it builds on penetration testing fundamentals. OSWE (WEB-300) suits those with web development experience. OSED (EXP-301) is often taken last as it requires low-level programming knowledge.

How should I prepare for OSCE3 in 2026?

Focus on one component at a time: 1) complete the official OffSec course and labs, 2) practice in home labs replicating exam conditions, 3) build automation scripts and payloads, 4) practice professional report writing, and 5) run timed simulations before scheduling each exam.
