Penetration Testing &
Red Team Operations

Offensive testing across Active Directory, web, mobile (Android), and network, with a bias for manual exploitation over scanner output.
Builds custom security tooling: fileless loaders, a homegrown C2, and evasion research tested against Defender and Kaspersky.
CRTO, CRTP, CRTA, CEH certified. Two years and 45+ client engagements behind the work on this page.

// 01 The case files

Known offenses.

Eight open cases. Everything listed has been run, on client work or in my own lab. Click a case to open its file.

  • BloodHound triage beyond shortest-path: derivative local admin chains and edges the default queries miss
  • Targeted Kerberoasting: SPN hunting, then offline cracking tuned to the password policy
  • AS-REP Roasting: preauth-disabled accounts, cracked offline
  • RBCU abuse: read access to one object is often enough to take it over
  • DCSync or forgery: picking the quieter path based on the noise the client will tolerate
  • Token impersonation: the last hop to domain admin

  • IDOR by object ID pattern: sequential IDs, UUID leaks in responses, role flips
  • Business logic races: coupon stacking, redemption races, step skipping
  • Auth architecture flaws: JWT confusion, session fixation, OAuth misflows
  • Blind SQLi: time-based and out-of-band channels where errors are suppressed
  • Chain building: low findings combined into full account takeover
  • Retest discipline: every fix is verified before a finding is closed
  • APK decompilation: exported components, backup and debuggable flags
  • Storage forensics: SharedPreferences tokens, unencrypted SQLite, logs
  • Weak cryptography: hardcoded keys, static IVs, and ECB mode where it should never appear
  • Deep link abuse: exported intents hijacked live on device
  • Pinning bypass: traffic inspection when the app fights back
  • External truth sweep: what answers on the wire vs what the asset list claims
  • Foothold expansion: one credential to the whole flat network
  • Manual service exploitation: scanner verdicts verified by hand
  • Segmentation validation: proving the guest VLAN can reach tier-0
  • Fileless pipeline: fetch, decode, RW to RX, execute, zero disk writes
  • C2 discipline: register, poll, rekey every session
  • Sandbox patience: randomized sleeps outlast detonation windows
  • Isolated verdicts: Defender, Bitdefender and Sophos tested one change at a time

Full methodology in build log 01, build log 02 and build log 04, PoC evidence included.

  • PE anatomy: DOS header to section table, mapped by hand
  • Base relocations: the delta applied to every absolute address
  • IAT resolution: imports wired without the loader's help
  • Alert intuition: why hollowing detections fire, from the inside

The whole ritual is written up in build log 03, PoC video included.

  • Dual telemetry: Bitdefender GravityZone and Sophos MDR review
  • Phishing forensics: header and attachment analysis with a clear verdict on every mail
  • IR drills: host isolation under pressure
  • Feedback loop: alert reading that sharpened the offense
  • CVSS v3.1: scored against the client's environment, not defaults
  • Executive summaries: written for the CTO, not the scanner
  • Implementable fixes: remediation a developer can act on
  • Verification retests: prove the patch, close the case

Full-timeHyderabad, IndiaOn-siteVAPT · Red team
  • Engagement ownership: I run each engagement end to end, from scoping with the client through exploitation, reporting, and the remediation retest.
  • Coverage: web applications, Android apps (MASVS), internal and external networks, and Active Directory environments.
  • Malware triage: reverse engineering samples that surface in client cases and feeding indicators back to the client's defenses.
  • Reporting: CVSS v3.1 scoring, executive summaries, and a retest of every fix before the engagement closes.
Full-timeHyderabad, IndiaOn-siteOffense + defense
  • Web pentesting: tested applications in Burp Suite Pro against the OWASP Top 10, reporting IDOR, SQL injection, XSS, and broken access control.
  • Endpoint telemetry: worked Bitdefender GravityZone and Sophos MDR queues during incident response drills and helped isolate compromised hosts.
  • Phishing analysis: inspected headers and attachments to confirm spoofed senders and malicious payloads.
