Ahmia is a search engine for services on the Tor network. It indexes hidden services, which require the Tor browser bundle to access, and states that abuse material is not allowed and is removed from the index. The project is developed as free and open source software, with a crawler, an index and a search website.
The Guardian SecureDrop is a tool for securely sending messages and documents to the Guardian. It uses the Tor network to hide where messages came from, and communication is encrypted in transit and on the server. Sources access it through an onion URL using the Tor browser.
onionsearch is a Python script that scrapes URLs on different .onion search engines. It is distributed on PyPI as version 1.3, released on October 22, 2021, under the GNU General Public License v3. The package page states the author has not provided a project description.
Stem is a Python controller library for Tor. It implements Tor's directory and control specifications, allowing scripts and applications to interact with the Tor process through its control protocol. The latest version is 1.8.1, released September 2022, and the project is noted as mostly unmaintained. It requires only Python.
This arXiv paper proposes an end-to-end scalable architecture for early identification of new Tor sites and daily analysis of their content. It is built on an open source big data stack including Kubernetes, Kafka, Kubeflow and MinIO, discovering onion addresses across several sources, downloading HTML from Tor, deduplicating with MinHash LSH and categorizing with BERTopic modeling. In 93 days it identified 80,049 onion services and characterized 90% of them.
CRATOR is a proposed dark web crawler described in an arXiv paper. It is designed to extract pages that handle security protocols such as captchas, using seed URL lists, link analysis and scanning to discover content, with user-agent rotation and proxy usage for anonymity. The authors report evaluation using coverage, performance and robustness metrics, and suggest threat intelligence, cybersecurity and online investigation applications.
SecureDrop for Sources is a documentation guide introducing sources to using SecureDrop. SecureDrop is a tool news organizations and NGOs use for secure and anonymous communication between whistleblowers and journalists. Submitted information is encrypted, no personal information is collected, and it is not a cloud service. It accepts messages and individual file uploads up to 500MB.
