Description
We warn on every application download, which causes warning fatigue and doesn't help users make good decisions. We should track the reputation of download URLs and hashes.
See Security/Features/Application_Reputation_Design_Doc for implementation details.
Prefs
- browser.safebrowsing.appRepURL: server endpoint for remote lookups
- browser.safebrowsing.downloads.enabled: enables application reputation checks for downloaded files
- browser.safebrowsing.downloads.remote.enabled: enables remote lookups (requires the previous pref)
- browser.safebrowsing.downloads.remote.timeout_ms: timeout for the remote lookups
- browser.safebrowsing.malware.enabled: enables malware checks (required by application reputation)
- urlclassifier.downloadAllowTable
- urlclassifier.downloadBlockTable: list of URLs serving malware binaries
Engineering
Most of the code lives in toolkit/components/downloads/ApplicationReputation.cpp.
QA
To turn on debugging output, export the following environment variable:
NSPR_LOG_MODULES="ApplicationReputation:5"
Documentation
- API Documentation available internally under NDA
- Chromium source code
- Announcement blog post
