Security
  • Kali Linux Forensics Tools

    Kali Linux is a powerful Operating system especially designed for Penetration Tester and Security Professionals. Most of its features and tools are made for security researchers and pentesters but it has a separate “Forensics” tab and a separate “Forensics” mode for Forensics Investigators.
    Forensics is becoming very important in Cyber Security to detect and backtrack Black Hat Criminals. It is essential to remove Hackers’ malicious backdoors/malwares and trace them back to avoid any possible future incidents. In Kali’s Forensics mode, Operating System doesn’t mount any partition from System’s hard drive and doesn’t leave any changes or fingerprints on host’s system.

    Kali Linux comes with pre-installed popular forensics applications and toolkits. Here we’ll review some famous open source tools present in Kali Linux.

  • What is SSH (Secure shell protocol)?

    SSH stands for Secure Shell which is a security protocol based on the application layer. We use the SSH to securely access the remote servers and Desktops to execute various commands. In short, we can control the complete system remotely, if we have login information and SSH server access. Because The Secure Shell (SSH) is a cryptographic network protocol designed to replace the Telnet and access the remote system even on the unsecured remote shell by encrypting data before sending.

  • Security Researcher Discovers Flaws In Yelp-For-MAGAs App, Developer Threatens To Report Him To The Deep State

    Even a cursory look at past stories we've done about how companies treat security researchers who point out the trash-state of their products would reveal that entirely too many people and companies seem to think shooting the messenger is the best response. I have never understood the impulse to take people who are essentially stress-testing your software for free, ultimately pointing out how the product could be safer than it is, and then threatening those people with legal action or law enforcement. But, then, much of the world makes little sense to me.

    Such as why a Yelp-for-MAGA people should ever be a thing. But it absolutely is a thing, with conservative news site 63red.com releasing a mobile app that is essentially a Yelp-clone, but with the twist that its chief purpose is to let other Trump supporters know how likely they are to be derided when visiting a restaurant. This is an understandable impulse, I suppose, given the nature of politics in 2019 America, though the need for an app seems like overkill. Regardless, the app was released and a security researcher found roughly all the security holes in it.

  • “Yelp, but for MAGA” turns red over security disclosure, threatens researcher

    But the safe space for 63red founder Scott Wallace was violated quickly when French security researcher Elliot Alderson discovered some fundamental security flaws in Safe's architecture—making it not so safe.

    Because the application is build in React Native, a JavaScript- and JSX-based scripting language that basically turns Web apps into "native" Apple iOS and Android applications, the entire architecture of the application is available to anyone who downloads and unpacks it. And in that code, Alderson discovered a few things: [...]

Fedora 30 Workstation review - Smarter, faster and buggier

Fedora 30 is definitely one of the more interesting releases of this family in a long-time. It brings significant changes, including solid improvements in the desktop performance and responsiveness. Over the years, Fedora went from no proprietary stuff whatsoever to slowly acknowledging the modern needs of computing, so now it gives you MP3 codecs and you can install graphics drivers and such. Reasonable looks, plus good functionality across the board. However, there were tons of issues, too. Printing to Samba, video screenshot bug, installer cropped-image slides, package management complications, mouse cursor lag, oopses, average battery life, and inadequate usability out of the box. You need to change the defaults to have a desktop that can be used in a quick, efficient way without remembering a dozen nerdy keyboard shortcuts. All in all, I like the freshness. In general, it would seem the Linux desktop is seeing a cautious revival, and Fedora's definitely a happy player. But there are too many rough edges. Well, we got performance tweaks after so many years, and codecs, we might get window buttons and desktop icons one day back, too. Something like 6/10, and definitely worth exploring. I am happy enough to do two more tests. I will run an in-vivo upgrade on the F29 instance on this same box, and then also test the distro on an old Nvidia-powered laptop, which will showcase both the support for proprietary graphics (didn't work the last time) and performance improvements, if they scale for old hardware, too. That's all for now. Read more

  • Illumos-Powered OmniOS Gets Updated Against MDS / ZombieLoad Vulnerabilities
    While it was just earlier this month that the OpenSolaris/Illumos-based OmniOS saw a big LTS release, it's already been succeeded by a new release given the recent Intel MDS / Zombieload CPU vulnerabilities coming to light. There are new spins of OmniOS for all supported releases. These new OmniOS Community Edition releases mitigate against the Multiarchitectural Data Sampling (MDS) vulnerabilities and also bundle in the updated Intel CPU microcode.
  • Hackers Hack A Forum For Hacked Accounts: Here’s How
    A group of hackers failed to deploy security mechanisms to secure the storage where they store hacked accounts and another hacker group hacked it. The story is indeed funny and real. Infamous forum named OGUSERS which is popular amongst hackers for obtaining “OG” Instagram, Twitter usernames, hacked accounts of Domino’s Pizza, Steam, PlayStation Network, and other online accounts was hacked by a hacker group and its data was published in another hacker forum.
  • Security Announcement: Disabling SMT by default on affected Intel processors
    This is an important announcement with an upcoming change in the next Core Update of IPFire. Because of the recent vulnerabilities in Intel processors, the IPFire team has decided, that - to keep systems as secure as possible - Simultaneous Multi-Processing (SMT) is automatically disabled if the processor is vulnerable to one of the attacks. SMT is also called Intel(R) Hyper-Threading Technology and simulates more virtual cores than the system has. This allows to perform faster processing when applications benefit from it. Unfortunately with networking, we benefit from that. Therefore the effect of disabling SMT will be a very signifiant performance impact of around 30% or more. Applications that will be affected in IPFire are the firewall throughput itself as well as other CPU and memory-bound tasks like the web proxy and the Intrusion Prevention System. On systems that are not vulnerable for this attack, SMT is being left enabled. If you still want to disable it, please do so in the BIOS of your firewall.
