Someone on Torrent Sites Kept Fucking with My Sonarr

Original Article ↗ Hacker News Discussion ↗

Malicious Windows executables masquerading as TV episodes are flooding public torrent indexes and confusing automation tools like Sonarr, leading some users to unknowingly download info‑stealing malware. Commenters trade mitigation strategies—blocking .exe and similar file types in torrent clients or Sonarr, moving to curated private trackers or Usenet, or adding external cleanup tools—while debating the hassles of ratios, seedboxes, and the increasingly fragmented *arr ecosystem. Several also note that this kind of booby-trapped piracy is as old as file sharing itself, arguing that better defaults and user education matter more than blaming any single app.

Malware-Filled Torrents and Sonarr Issues

  • Many report a recent flood of fake TV torrents that are just .exe files, often the most-seeded results on public trackers.
  • Sonarr/Radarr happily pull these when misconfigured, confusing users who then find executables instead of media.
  • Several say this is an old problem in piracy, now resurfacing at scale.

Mitigations and Tools

  • Common advice: configure torrent clients (e.g., qBittorrent) and Sonarr/Radarr to block or fail downloads containing executables (.exe, .scr, .zip, etc.).
  • Sonarr has indexer “Fail Downloads → Executables” options; some use release profiles or indexer rules as a workaround.
  • Third-party helpers like cleanuparr and qbittorrent-sentinel scan and auto-remove suspect torrents.
  • Some run custom DHT crawlers (e.g., bitmagnet) with filtering.

Private Trackers vs Public Trackers

  • Pro-private-tracker: better curation, far less malware, more seeds, and reduced copyright-enforcement risk; many say they rarely think about this problem there.
  • Anti-/skeptical: joining is hard (invites/interviews), ratio rules feel like a time sink, seedboxes skew uploads, and pay-to-join trackers are called scams.
  • Some note bonus systems and freeleech make ratios manageable; others say strict sites are driving users away.

Usenet vs Torrents

  • Some prefer Usenet for reliability and speed; others note takedowns for anything but very recent content.
  • Reports that similar .exe payloads are starting to appear via Usenet indexers too.

*Complexity and Value of the arr Stack

  • Critics find the *arr ecosystem overcomplicated compared to “browser + torrent client + VLC.”
  • Defenders say modularity exists for legal deniability and that automation is indispensable for large libraries or family setups.

Security, OS Defaults, and User Behavior

  • Surprise that Windows Defender doesn’t always block these infostealers, though some say it does catch many.
  • Discussion of Windows hiding file extensions by default, making .exe masquerades more effective; contrasted with Unix-like systems where extensions are cosmetic.

AI-Generated Article and Reverse Engineering

  • Multiple commenters assert the blog post reads heavily like LLM-generated text, with a distinctive “Claude-style” tone.
  • Some still value the reverse-engineering walkthrough; others dismiss it as “slop” and say the core problem is misconfiguration.

Broader Piracy Attitudes

  • Several frame malware and scams as a perennial “cost of piracy.”
  • Others emphasize that with careful tooling (private trackers, Usenet, filters) the risk can be largely mitigated.
