FlareSolverr
Proxy server to bypass Cloudflare protection
FlareSolverr is a proxy server to bypass Cloudflare and DDoS-GUARD protection. FlareSolverr starts a proxy server, and it waits for user requests in an idle state using few resources. When some request arrives, it uses puppeteer with the stealth plugin to create a headless browser (Firefox). It opens the URL with user parameters and waits until the Cloudflare challenge is solved (or timeout). The HTML code and the cookies are sent back to the user, and those cookies can be used to bypass Cloudflare using other HTTP clients. Web browsers consume a lot of memory. If you are running FlareSolverr on a machine with few RAM, do not make many requests at once. With each request, a new browser is launched. It is also possible to use a permanent session. However, if you use sessions, you should make sure to close them as soon as you are done using them. It is recommended to install using a Docker container because the project depends on an external browser that is already included. -

Mobile Verification Toolkit
Helps with conducting forensics of mobile devices
Mobile Verification Toolkit (MVT) is a collection of utilities to simplify and automate the process of gathering forensic traces helpful to identify a potential compromise of Android and iOS devices. It has been developed and released by the Amnesty International Security Lab in July 2021 in the context of the Pegasus project along with a technical forensic methodology and forensic evidence. MVT is a forensic research tool intended for technologists and investigators. Using it requires understanding the basics of forensic analysis and using command-line tools. This is not intended for end-user self-assessment. If you are concerned with the security of your device please seek expert assistance. Compare extracted records to a provided list of malicious indicators in STIX2 format. Generate JSON logs of extracted records, and separate JSON logs of all detected malicious traces. -

PhoneInfoga
Information gathering framework for phone numbers
PhoneInfoga is an open-source intelligence framework focused on gathering and analyzing information related to international phone numbers. The tool aggregates data from multiple scanners and external services to provide contextual intelligence such as country, carrier, line type, and potential VoIP provider details. It is designed primarily for investigators, analysts, and security researchers who need structured phone-number reconnaissance rather than real-time tracking. PhoneInfoga intentionally avoids automation of invasive actions and instead assists manual investigations by correlating publicly available data. The platform includes both a command-line interface and a web client backed by a REST API, making it suitable for integration into larger investigative workflows. Because it relies heavily on external data sources, its effectiveness depends on proper configuration of scanners and APIs. -

Flipper Zero BadUSB
Repository for my flipper zero badUSB payloads
The repository is a public GitHub collection of BadUSB payloads prepared to run from a Flipper Zero device; it’s presented as a plug-and-play library that bundles payload scripts, a README, and supporting files so users can pick and use payloads without heavy setup. The project is heavily PowerShell-oriented and organized into a payloads folder with documentation (README, FAQs) and helper scripts, and the author says they formatted the collection to be easy for others to use. The maintainer also set up short-URL infrastructure to simplify embedding webhooks or tokens into compact one-liners for payload configuration, and the repo includes social/contact links and acknowledgments to related projects. The repository is actively used by a community (many stars, forks and hundreds of commits), and the author explicitly warns about responsible use and includes guidance in the docs. -

YARA
The pattern matching swiss knife for malware researchers
YARA is a tool aimed at (but not limited to) helping malware researchers to identify and classify malware samples. With YARA you can create descriptions of malware families (or whatever you want to describe) based on textual or binary patterns. Each description, a.k.a rule, consists of a set of strings and a boolean expression which determines its logic. YARA is multi-platform, running on Windows, Linux and Mac OS X, and can be used through its command-line interface or from your own Python scripts with the yara-python extension. YARA-CI may be a useful addition to your toolbelt. This is GitHub application that provides continuous testing for your rules, helping you to identify common mistakes and false positives. If you plan to use YARA to scan compressed files (.zip, .tar, etc) you should take a look at yextend, a very helpful extension to YARA developed and open-sourced by Bayshore Networks. -

SimpleX
The first messaging platform operating without user identifiers
Other apps have user IDs: Signal, Matrix, Session, Briar, Jami, Cwtch, etc. SimpleX does not, not even random numbers. This radically improves your privacy. The video shows how you connect to your friend via their 1-time QR-code, in person or via a video link. You can also connect by sharing an invitation link. Temporary anonymous pairwise identifiers SimpleX uses temporary anonymous pairwise addresses and credentials for each user contact or group member. It allows to deliver messages without user profile identifiers, providing better meta-data privacy than alternatives. Many communication platforms are vulnerable to MITM attacks by servers or network providers. To prevent it SimpleX apps pass one-time keys out-of-band when you share an address as a link or a QR code. Double-ratchet protocol. OTR messaging with perfect forward secrecy and break-in recovery. NaCL cryptobox in each queue to prevent traffic correlation between message queues if TLS is compromised.
