About #opendir
- Definition: an HTTP server (often nginx / Apache / IIS) configured with directory autoindex enabled, exposing the contents of a folder. When the folder belongs to an attacker (staging server, kit drop, panel root) the listing reveals payloads, scripts and operator artefacts.
- Why researchers track them: open directories are a high-yield source of fresh IOCs. A single opendir often hosts multiple loaders, second-stage payloads, exfiltrated-data archives and YARA-friendly scripts; researchers download, hash and tag each artefact in bulk.
- Detection: for defenders, periodic scans of organisation egress for `Index of /` patterns; for hunters, services like ODIN by The DFIR Report, URLscan tag filters, and certificate-transparency-driven sweeps.

Frequently asked questions
What is an opendir?
An opendir (open directory) is a web folder where directory autoindexing is enabled, exposing all files inside as a clickable listing. When attackers misconfigure their staging servers this way - which happens often - researchers can browse the listing, download every artefact and reverse-engineer the kit or payload set.
How do opendirs end up in this feed?
Public researchers post URLs to attacker opendirs they discover, tagged #opendir. The TweetFeed pipeline picks up these URLs (and the IPs/domains hosting them) and republishes them in CSV, JSON and RSS within 15 minutes. Many opendirs are short-lived: the operator notices the leak and locks down the directory or rotates infrastructure.
How is this list updated?
Every 15 minutes. The TweetFeed pipeline scrapes RSS feeds from public Twitter/X security researcher accounts and lists, extracts IOCs, tags them with the relevant malware family or threat actor, and republishes the result in CSV, JSON and RSS. Opendir-tagged IOCs are surfaced on this page within the next 15-minute tick. The page itself is regenerated daily by a GitHub Action.
