All mined coins go directly to a wallet controlled by the attacker. The victim receives nothing except degraded performance, higher electricity bills, and potential hardware damage.
Add these domains to your hosts file (C:\Windows\System32\drivers\etc\hosts):

The “pwnhack.com miner” is a browser‑side cryptocurrency mining payload written primarily in JavaScript (with optional WebAssembly modules for performance). Its purpose is to co‑opt the CPU cycles of any unsuspecting visitor’s device to mine proof‑of‑work coins—most commonly Monero (XMR), because its CryptoNight‑style algorithm is CPU‑friendly and offers a degree of anonymity for the miner’s operator.
Key characteristics reported by multiple threat‑intel sources: All mined coins go directly to a wallet
| Feature | Description |
|---------|-------------|
| Delivery vector | Injected via compromised third‑party scripts (e.g., compromised CDN libraries, malicious ad networks) or through direct exploitation of vulnerable WordPress plugins. |
| Obfuscation | Heavily minified, base64‑encoded, and split across several <script> tags. Some variants use self‑defending code that detects debugging tools (e.g., Chrome DevTools) and disables the miner. |
| Persistence | Not persistent on the host; the script runs only while the page is open. However, repeated infections on high‑traffic sites can generate substantial hash power over time. |
| Coin selection | Primarily Monero, but some variants have been observed switching to Raven or Verge depending on profitability. |
| Command‑and‑Control (C2) | The script fetches a tiny configuration file from a subdomain of pwnhack.com (e.g., config.pwnhack.com) containing the pool address, wallet ID, and mining intensity. |
| Anti‑detection | Dynamically throttles CPU usage based on the device’s performance (e.g., limiting itself to ~30 % of available cores) to avoid obvious performance degradation that would alert users. |
While the miner’s stealth tactics make it challenging for a casual user, security teams can still identify and block it using layered defenses: Alternatively, on your router, block outgoing traffic to
