  • Riccardo Padovani: Responsible disclosure: improper access control in Gitlab private project.

    As I said back in September with regard to a responsible disclosure about Facebook, data access control isn’t easy. While it can sound quite simple (just give access to the authorized entities), it is very difficult, both on a theoretical side (who is an authorized entity? What does authorized mean? And how do we identify an entity?) and on a practical side.

  • Integrating Password and Privilege Management for Unix and Linux Systems[Ed: More spammy pages under the guise of "whitepaper"]

    Unix and Linux build the foundation for most business-critical systems. Thus, they present target-rich environments for cyber-attackers. Privileged Access Management (PAM) helps to mitigate such risks. To succeed, security teams must follow an integrated approach, covering both privilege elevation and centralized management of shared account credentials.

  • How Not to Acknowledge a Data Breach

    My guess is that what Wipro means by “zero-day” is a malicious email attachment that went undetected by all commercial antivirus tools before it infected Wipro employee systems with malware.

  • Facebook stored millions of Instagram passwords in plain text

    Facebook says it stored millions of Instagram users’ passwords in plain text, leaving them exposed to people with access to certain internal systems. The security lapse was first reported last month, but at the time, Facebook said it only happened to “tens of thousands of Instagram users,” whereas the number is now being revised up to “millions.” The issue also affected “hundreds of millions of Facebook Lite users” and “tens of millions of other Facebook users.”

  • Update: Facebook passwords for hundreds of millions of users were exposed to Facebook employees

    Facebook confirmed March 21 that hundreds of millions of user passwords were being stored in a “readable format” within its servers, accessible to internal Facebook employees—including millions more Instagram users than previously thought. Affected users will be notified, Facebook said, so they can change those passwords.

  • Facebook 'unintentionally' uploaded 1.5 million people's email contacts without asking

    This is how it unfolded: a security researcher spotted that Facebook was asking some users to put in their email passwords when they signed up with a new account to verify their identity. Business Insider then experimented with what would happen if you were brave/mad enough to do so and found that a message popped up saying it was "importing" its contacts without having the decency to check that was okay first.

    Apparently, 1.5 million people just accepted this as just one of those things, and the information was then used to build up Facebook's uncanny ability to predict when you know somebody.

  • In new gaffe, Facebook improperly collects email contacts for 1.5 million

    Facebook's privacy gaffes keep coming. On Wednesday, the social media company said it collected the stored email address lists of as many as 1.5 million users without permission. On Thursday, the company said the number of Instagram users affected by a previously reported password storage error was in the "millions," not the "tens of thousands" as previously estimated.

  • Facebook says it 'unintentionally uploaded' 1.5 million people's email contacts without their consent

    Since May 2016, the social-networking company has collected the contact lists of 1.5 million users new to the social network, Business Insider can reveal. The Silicon Valley company said the contact data was "unintentionally uploaded to Facebook," and it is now deleting them.

  • With Nation Distracted by Mueller Report, Facebook Admits Millions of Users' Passwords Affected by Latest Privacy Breach

    On Thursday, Facebook added to a blog post from March 21 to let users know that instead of storing tens of thousands of Instagram passwords, as it had reported last month, the number of users affected by the privacy breach was in the millions. Facebook is the parent company of Instagram.

    "Since this post was published, we discovered additional logs of Instagram passwords being stored in a readable format," wrote Pedro Canahuati, vice president of Engineering, Security and Privacy. "We now estimate that this issue impacted millions of Instagram users. We will be notifying these users as we did the others."

    The stored passwords were found in January during a routine security check, according to Facebook. In March, when the breach was first announced, the company said the passwords were never visible to anyone outside of Facebook.

  • How To Install MongoDB on AlmaLinux 9 - idroot

    In this tutorial, we will show you how to install MongoDB on AlmaLinux 9. For those of you who didn’t know, MongoDB is a high-performance, highly scalable document-oriented NoSQL database. Unlike in SQL databases where data is stored in rows and columns inside tables, in MongoDB, data is structured in JSON-like format inside records which are referred to as documents. The open-source attribute of MongoDB as a database software makes it an ideal candidate for almost any database-related project. This article assumes you have at least basic knowledge of Linux, know how to use the shell, and most importantly, you host your site on your own VPS. The installation is quite simple and assumes you are running in the root account, if not you may need to add ‘sudo‘ to the commands to get root privileges. I will show you the step-by-step installation of the MongoDB NoSQL database on AlmaLinux 9. You can follow the same instructions for CentOS and Rocky Linux.

  • Self-host a Ghost Blog With Traefik

    Ghost is a very popular open-source content management system. Started as an alternative to WordPress and it went on to become an alternative to Substack by focusing on membership and newsletter. The creators of Ghost offer managed Pro hosting but it may not fit everyone's budget. Alternatively, you can self-host it on your own cloud servers. On Linux handbook, we already have a guide on deploying Ghost with Docker in a reverse proxy setup. Instead of Ngnix reverse proxy, you can also use another software called Traefik with Docker. It is a popular open-source cloud-native application proxy, API Gateway, Edge-router, and more. I use Traefik to secure my websites using an SSL certificate obtained from Let's Encrypt. Once deployed, Traefik can automatically manage your certificates and their renewals. In this tutorial, I'll share the necessary steps for deploying a Ghost blog with Docker and Traefik.
