Aspiegel
Bot User-Agent:aspiegel
🤖 Overview
AspiegelBot is a legitimate web crawler operated by Aspiegel Limited, the Irish subsidiary that manages the Huawei AppGallery distribution platform. Its primary purpose is to discover, verify, and index publicly available Android application packages (.apk files) and app metadata (titles, descriptions, developer names, ratings) so that users can find apps through Huawei’s app store.
🌐 Technical Behavior
The bot initiates HTTP/1.1 GET requests to retrieve robots.txt, HTML pages, and XML sitemaps, then follows hyperlinks to locate APK download links. It respects HTTP 429 responses and implements exponential backoff. AspiegelBot sources from multiple IP ranges registered to the AS213238 autonomous system owned by Aspiegel Limited, with a typical crawl frequency of one request every 2–3 seconds per domain. The crawler does not fetch images or JavaScript files unless explicitly linked from app listing pages. It uses TLS 1.2 or higher and often sends a Referer header pointing to Huawei AppGallery’s own domain.
📋 robots.txt Compliance
AspiegelBot has been documented to fully honor Disallow directives in robots.txt since its public launch in 2019. Official support pages from Huawei’s developer documentation state that publishers can block the bot by adding User-agent: AspiegelBot and Disallow: /. There are no known reports of the bot ignoring explicit crawl instructions, making it compliant with RFC 9309.
🔍 Detection Indicators
The primary User-Agent string is AspiegelBot/1.0, sometimes appended with version numbers like 2.0. Additional HTTP headers include X-Aspiegel-Crawl: true and a custom From: [email protected] header. Reverse DNS lookups on connecting IPs resolve to subdomains under aspiegel.com. IP ranges are publicly listed in the RIPE database under AS213238, covering blocks such as 185.126.160.0/24.
📊 Data Usage
The collected APK links and metadata feed directly into the Huawei AppGallery index, enabling users to discover third‑party apps not hosted by Huawei. Metadata (app name, category, developer) is parsed from HTML pages, while the actual APK files remain on the publisher’s servers. No personal user data is harvested. Huawei’s developer guidelines confirm that the data is used solely for app store searching and not for machine learning or advertising.
⚙️ Rate Limiting Policy
AspiegelBot should be rate‑limited because its steady crawl rate can consume significant bandwidth on busy sites, and because Huawei AppGallery relies on up‑to‑date app listings. Administrators are advised to apply a threshold of 10 requests per minute per IP block to prevent resource exhaustion while allowing the bot to remain effective.
