We've put together a FAQ that offers answers to most questions raised. The solution recently turned 1.x, introducing a major architectural change: the introduction of a local REST API. They believe that the crowd is key to the mass hacking plague we are experiencing, and that Open Source is the best lever to create a community and have people contribute their knowledge to the project, ultimately make it better and more secure. Rather, they are strong Open Source believers. The project's founders have been working on open-source projects for decades - they didn't just jump on the train. It was clear to the founders that Open Source was going to be one of the main pillars of CrowdSec. Ultimately, CrowdSec leverages the power of the community to create an extremely accurate IP reputation system that benefits all its users. As for the IP that aggressed your machine, you can choose to remedy the threat in any manner you feel appropriate.

The goal is to leverage the power of the crowd to create a real-time IP reputation database. If this signal passes the curation process, the IP is then redistributed to all users sharing a similar technological profile to 'immunize' them against this IP. If your agent detects such aggression, the offending IP is then dealt with and sent for curation. It uses a behavior analysis system to qualify whether someone is trying to hack you, based on your logs.

It was inspired by Fail2Ban and aims to be a modernized, collaborative version of that intrusion-prevention tool.ĬrowdSec is free and open-source (under an MIT License), with the source code available on GitHub.

“Users can help keep themselves secure by applying current updates or downloading the latest Keybase software with all current security updates,” the spokesperson advised.Slashdot reader b-dayyy writes: CrowdSec is a massively multiplayer firewall designed to protect Linux servers, services, containers, or virtual machines exposed on the Internet with a server-side agent.

We addressed the issue identified by the Sakura Samurai researchers on our Keybase platform in version 5.6.0 for Windows and macOS and version 5.6.1 for Linux,” Zoom’s spokesperson told. “Zoom takes privacy and security very seriously and appreciates vulnerability reports from researchers. For discovering this flaw, the Sakura Samurai team received a $1,000 bug bounty.

The patches were released on 23 January 2021, so if you are still using the old version, immediately update your Keybase client. The flaw was reported to Zoom and fixed in Keybase 5.6.0 for Windows and Keybase 5.6.1 for macOS and Linux. The flaw in Keybase was identified during Zoom’s bug-hunting program after it acquired the project in May 2020. This could be detrimental for privacy-focused users as the primary reason they picked up Keybase is to keep their data secure from authoritarian regimes. If an attacker can establish local access on the device, they can easily access files, which the user believes have been deleted on Keybase. Recovered and unencrypted image on WindowsImage: John J Hacking Typically, the folder remains alive on the local storage until the image uploading action lasts. This means the images were still retrievable in cleartext format.Īccording to a blog post published by researchers, the bug also prevents the “uploadtemps” folder from getting immediately wiped, as it usually happens. However, despite showing them as deleted, the pictures were neither removed on the local cache nor from the “uploadtemps” directories due to the bug. In the Keybase app, under normal circumstances, after deleting a picture or enabling the explode feature, which activates time-based deletion of images, the pictures are expected to be wiped from the app’s cache. It impacts the app’s cleartext image storing cache and is found in all desktop versions of the app across all platforms, including Windows, Mac, and Linux. Bug Affects Keybase App’s Picture Storing MechanismĪccording to Jackson and his team, the bug carries the identifier CVE-2021-23827. However, Jackson reported in the company’s latest report that the bug could compromise Keybase users’ privacy. This feature-rich app offers comprehensive privacy and security.

The app is regarded as one of the best for encrypted communication. John Jackson and researchers at Sakura Samurai including Aubrey Cottle, Jackson Henry, and Robert Willis have identified a critical vulnerability in the Keybase app that puts the privacy of Windows, macOS, and Linux users at risk. Keybase is owned by Zoom and currently has almost half a million privacy-focused users.
