    Course 36 - Windows Forensics and Tools | Episode 8: Efficiency, Evidence, and Forensics

    In this lesson, you’ll learn about: Windows Prefetch and forensic execution tracking1. What is Windows Prefetch?A Windows performance feature designed to:Speed up application startupReduce disk access time🔹 Key IdeaIt becomes a forensic artifact that records program execution2. How Prefetch WorksWindows monitors the first seconds of an application launchIt records:Files accessedExecution behavior patterns👉 Result:A cached “startup map” is created for faster future runs3. Prefetch File Structure🔹 Naming FormatApplication name + hashThe hash is an 8-character hexadecimal value🔹 Purpose of the HashDerived from the application pathHelps differentiate:Same program in different locations👉 Key Insight:Same executable in different folders = different Prefetch file4. Forensic Value of Prefetch🔹 What investigators can determineWhen a program was executedHow many times it was runWhether it ran from unusual locations5. The “Who, What, When” of Forensics🔹 Key Questions AnsweredWho: Which program was executedWhat: Which executable was runWhen: Last execution timestamp👉 Important:Prefetch is one of the strongest execution evidence sources in Windows6. Detecting Evidence Tampering🔹 Critical InsightPresence of cleanup tools is itself evidence🔹 ExampleIf a wiping tool appears in Prefetch:It proves the tool was executed👉 Key Idea:“Trying to hide evidence” becomes evidence itself7. Hidden Activity Discovery🔹 Prefetch can reveal:Hidden directoriesExternal storage usageEncrypted container activity🔹 Example targetsTrueCrypt volumesExternal USB drivesObfuscated folders8. System Evolution🔹 Related Windows TechnologiesSuperfetchReadyBoost👉 Purpose:Improve system responsiveness and memory usage9. Registry Control of Prefetch🔹 Key ConceptPrefetch behavior can be enabled/disabled via registry settings🔹 Forensic ImportanceInvestigators check registry keys to see:If Prefetch was disabled intentionallyIf someone tried to hide activity10. Investigation Workflow🔹 How analysts use PrefetchLocate Prefetch filesExtract execution metadataAnalyze timestamps and countsCorrelate with other artifactsKey TakeawaysPrefetch records application execution behavior for performanceIt is a powerful forensic artifact for tracking user activityFile names include hashed execution pathsIt can reveal hidden tools, drives, and user behaviorDisabling Prefetch may itself indicate suspicious activityBig PicturePrefetch helps investigators:👉 Move from “what exists on disk” → “what was actually executed”Mental ModelProgram run → Prefetch created → Execution metadata stored → Timeline reconstructed You can listen and download our episodes for free on more than 10 different platforms: https://linktr.ee/cybercode_academy

    Course 36 - Windows Forensics and Tools | Episode 6: From System Hives to Forensic Analysis

    In this lesson, you’ll learn about: Windows Registry structure and forensic analysis1. What is the Windows Registry?A centralized configuration database in WindowsStores system, user, and application settings🔹 Core IdeaThink of it as the brain of Windows configuration2. Registry StructureThe registry is organized in a strict hierarchy:🔹 ComponentsHivesKeysSubkeysValues🔹 AnalogyHive → main database fileKey → folderValue → actual data entry3. Main Root Keys🔹 Key Windows Registry RootsHKEY_LOCAL_MACHINE (HKLM)HKEY_CURRENT_USER (HKCU)🔹 What they representHKLM → system-wide settingsHKCU → settings for the logged-in user4. Physical Storage of Registry HivesStored on disk in:C:\Windows\System32\config 🔹 Why this mattersInvestigators can extract registry data directly from diskEven if Windows is not bootable5. Core HKLM Sub-Hives🔹 SAM (Security Accounts Manager)Stores:User accountsPassword hashes🔹 SECURITY HiveStores:Local security policyLSA secretsAuthentication data🔹 SOFTWARE HiveStores:Installed applicationsConfiguration settings🔹 SYSTEM HiveStores:DriversServicesBoot configuration👉 Key Insight:These hives are critical for system and user reconstruction6.

    Course 36 - Windows Forensics and Tools | Episode 5: Structure and Forensic Significance

    In this lesson, you’ll learn about: Windows Security Identifiers (SIDs) and user tracking1. What is a Security Identifier (SID)?A SID (Security Identifier) is a unique value assigned to every:UserGroupSecurity principal (system accounts, services)🔹 Core IdeaIt acts like a permanent digital fingerprint in WindowsUsed internally instead of usernames👉 Key Property:A SID is never reused, even if the account is deleted2. Why SIDs ExistWindows needs a stable way to identify identitiesUsernames can changeSIDs cannot🔹 Example UsePermissions are assigned to SIDs, not namesAccess control checks rely on SID matching3. SID in Access Tokens🔹 What happens at login?Windows creates an access tokenThis token contains:User SIDGroup SIDsPrivileges👉 Key Insight:Every process inherits this tokenThis determines what the user can do4. Structure of a SIDA SID is not random—it has a strict format:🔹 Main ComponentsIdentifier AuthoritySub-authority valuesRelative Identifier (RID)5. SID Breakdown Explained🔹 Identifier AuthorityDefines the system or domain originExample:Local machineDomain controller🔹 Sub-authoritiesRepresent hierarchical security structureProvide organizational uniqueness🔹 Relative Identifier (RID)The most specific partIdentifies the actual account6. Important RID Examples🔹 Common Built-in Accounts500 → Built-in Administrator501 → Guest account512 → Domain Admins group513 → Domain Users group🔹 Special Group“Everyone” group → universal access SID👉 Key Insight:RID tells you exactly what type of account it is7. How SIDs Are Used in Security🔹 Access ControlFile permissions are assigned to SIDsNot usernames🔹 Authentication FlowLogin → SID loaded → permissions applied8. Forensic Importance of SIDs🔹 What investigators can learnWhich user performed an actionWhether an account was deleted or renamedPrivilege escalation attempts🔹 Why it mattersEven if usernames change, SID stays the sameEnables long-term tracking of user behaviorKey TakeawaysSIDs are permanent unique identifiers in WindowsThey are used instead of usernames for security decisionsStored inside access tokens during loginStructured into authority, sub-authority, and RIDEssential for forensic tracking and access controlBig PictureSIDs help you:👉 Move from “who is the user?” → “what identity is truly behind the action?”Mental ModelUsername → Human labelSID → System truth You can listen and download our episodes for free on more than 10 different platforms: https://linktr.ee/cybercode_academy
