Understanding the recent DDoS attack against Read the Docs

Original Article

Hacker News Discussion

📝 Discussion Summary (Click to expand)

Theme 1 – Motives behind the attack are uncertain and widely speculated
Commenters repeatedly guessed why someone would target a documentation site: probing for a bigger attack, financial harm, ransom, nation‑state drills, or simply “for the pleasure of doing it.”

“My guess is that the attackers behind this attack were already probing us (they were) and they thought the window of opportunity might be closing.” – davidfischer
“Could be testing in preparation for attacking something more critical?” – SoftTalker
“Maybe just for the pleasure of doing it, too.” – lanyard‑textile
“Could have been a live‑fire exercise by a nation state.” – RobRivera

Theme 2 – Scrapers ignore readily available, efficient data dumps
Several participants noted that attackers hammer the site with requests even though complete archives (Git repos, ZIP files, Wikimedia dumps) are openly provided and would be far cheaper to obtain.

“Current evidence is that scrapers mostly aren't nearly considerate or sophisticated enough to take an 'archive of all content' option if one exists.” – simonw
“For somebody who knows a bit how things are set up… it's a no‑brainer that you can just 'git clone' entire linux kernel development history… Alas, large number of scrapers are not willing to spend those 10 minutes…” – kees99
“You can tell Claude to clone from github for Linux stuff all you want… it's still going to try web, and fail…” – nubinetwork

Theme 3 – Defensive measures involve trade‑offs and limited effectiveness
The discussion highlighted the site’s reliance on rate limits, JavaScript challenges, Cloudflare settings, and the difficulty of stopping attacks without harming legitimate users or incurring high costs.

“We didn't want to just challenge everyone. We use JS challenges but we try to use them sparingly.” – davidfischer
“It purposefully attacked areas that bypassed caching.” – braiamp
“What's the money reason this problem isn't handled at the ISP level?” – gopher_space
“JA3s are mostly useless. JA4s supersede them entirely… Bot detections are somewhat helpful but they don't solve scrapers/attacks by themselves.” – davidfischer

🚀 Project Ideas

DocDumpHub: Standardized Documentation Archive Service

Summary

  • Provides a simple, versioned archive endpoint (ZIP, markdown, git) for documentation sites so scrapers can download all content in one polite request instead of hammering individual pages.
  • Core value: reduces unnecessary traffic, lowers egress costs, and discourages aggressive scraping by offering a canonical dump.

Details

Key Value
Target Audience Documentation hosting platforms (Read the Docs, GitHub Pages, GitBook) and open‑source projects that publish docs.
Core Feature Automated generation and serving of immutable, content‑addressed archives per release/git tag, with metadata and content‑negotiation (Accept: application/zip, text/markdown).
Tech Stack Python/FastAPI, GitPython, object storage (S3/GCS), CDN edge caching, optional GitHub Actions workflow for trigger‑on‑push.
Difficulty Medium
Monetization Revenue-ready: tiered pricing based on bandwidth/storage; free tier for OSS projects.

Notes

  • HN users complained that scrapers ignore existing archive options (see kes99: “it’s a no‑brainer that you can just 'git clone'…”) and that offering a standard dump would deter abuse (perching_aix: “Is there a standard for exposing such sitedata dumps?”).
  • Would give docs admins a concrete lever to point scrapers at, reducing 404/302 churn described by davidfischer and braiamp.

ScraperSight: Adaptive Bot Detection & Mitigation Platform

Summary

  • Uses JA4+ TLS fingerprints, request‑behavior scoring, and dynamic JS challenges to detect and throttle scrapers that target non‑cached URLs (404/302 paths) before they cause cost spikes.
  • Core value: protects sites from layer‑7 DDoS/scraping attacks while keeping legitimate users frictionless.

Details

Key Value
Target Audience Site reliability engineers, CDN providers, SaaS platforms that host public documentation or APIs.
Core Feature Real‑time fingerprint extraction + behavioral scoring engine that serves adaptive challenges (JS interstitial, rate‑limit, or tarpit) and logs actionable intel.
Tech Stack Rust/Wasm for high‑speed packet inspection (e.g., using ntfy or eBPF), Redis for state, Prometheus/Grafana for metrics, plug‑in for Cloudflare Workers / nginx / Envoy.
Difficulty High
Monetization Revenue‑ready: SaaS subscription priced per million inspected requests (e.g., $10/M).

Notes

  • Commenters discussed JA4 usefulness and its limits (davidfischer, cute_boi) and the desire for better detection (Symbiote: “need JA3/4 fingerprinting”). ScraperSight would extend JA4 with behavior analysis to stop attackers that deliberately bypass caches (as braiamp noted: “purposefully attacked areas that bypassed caching”).
  • Provides a defensive layer that could have mitigated the Read the Docs attack without resorting to blunt “Under Attack” mode.

AbuseReport.io: ISP Abuse Reporting Automation

Summary

  • Automates the creation, enrichment, and delivery of abuse reports to ISPs when malicious traffic is detected, including whois lookup, evidence packets, and response tracking.
  • Core value: reduces the manual effort of fighting abuse at the source, encouraging ISPs to act on compromised hosts.

Details

Key Value
Target Audience Site admins, security teams, small‑to‑medium businesses that run public‑facing services and lack a dedicated abuse desk.
Core Feature Ingest web/server logs, match offending IPs to ISP via MaxMind/RIPE, generate templated abuse reports (email or ticket), attach sample logs/PCAP, and track remediation status via dashboard.
Tech Stack Node.js/Express, MaxMind GeoIP2, node-whois, SendGrid/SES for email, React + Redux UI, PostgreSQL for ticket store.
Difficulty Medium
Monetization Hobby (free open‑source) or Revenue‑ready: freemium model – free tier up to 100 reports/mo, paid plans for higher volume and API access.

Notes

  • Several HN participants lamented the difficulty of getting ISPs to act (AllanDark: “finding out who's on the other end … sue”; Onavo: “legal response…hard”). AbuseReport.io would streamline that process, making it practical for site owners to push back.
  • Would address the frustration expressed by john01dav and others about abuse reporting being a “black hole,” turning manual effort into an automated workflow.
