Go phish your own staff: Dev builds open-source fool-testing tool

Filed under
OSS
Security

The platform was written in Go and has been posted to GitHub where it's had more than 300 commits at the time of writing. It differs from some other anti-phishing platforms in part because it is hosted on premise rather than in the cloud, “There are many commercial offerings that provide phishing simulation/training [but] unfortunately, these are SaaS solutions that require you to hand over your data to someone else,” the GoFish team says.

  • Best practice - Don't serve writeable PHP files

    I deal with compromises often enough of PHP-based websites that I wish to improve hardening.

    One obvious way to improve things is to not serve PHP files which are writeable by the webserver-user. This would ensure that things like wp-content/uploads didn't get served as PHP if a compromise wrote valid PHP there.

  • New Cross-Platform Backdoors Go From Linux to Windows

    Kaspersky Lab has once again found a nasty little piece of malware that started out in Linux and made the jump to Windows. These cross-platform backdoors spy on the user and are by no means the first backdoor virus of this kind.

    The U.S. Department of Homeland Security (DHS) has spent about $6 billion on a firewall named EINSTEIN intrusion detection system. Officially known as the National Cybersecurity Protection System, the firewall is being developed with an intention to protect the U.S. government agencies against the malicious cyber attacks.

  • Another Serious Bug Hits OpenSSL, But this Time, It's No Heartbleed

    OpenSSL, the open source encryption toolkit that made headlines in 2014 for the Heartbleed security bug, has been hit by another serious vulnerability. This time, however, the real-world damage seems minimal.

    The project disclosed the bug, which results from a new method for generating numbers used for key exchanges, on Jan. 28. It assigned the bug a high severity level, presumably since the flaw could be exploited in order to decrypt data that is encrypted using OpenSSL, the protocol widely used for encrypting information transmitted to and from HTTPS-protected websites.

  • Your Smartphone Can Be Hacked Due To A Backdoor In Your Processor

    A new security vulnerability has been reported in the smartphones which use MediaTek Processors. MediaTek company is a Taiwan-based company which manufacturers processors for the budget range smartphones. The security bug was found because a debug feature was not closed on the smartphone after testing.

    A new bug has surfaced lately on the Android smartphones or tablets which use a MediaTek processor. These devices are vulnerable to remote hacking via a backdoor. This security vulnerability was discovered by a security researcher, Justin Case. The MediaTek company has been informed about the flaw. This security vulnerability is apparently due to a debug tool which was left open by MediaTek in the shipped devices.

  • Trojanized Android games hide malicious code inside images

    Over 60 Android games hosted on Google Play had Trojan-like functionality that allowed them to download and execute malicious code hidden inside images.

    The rogue apps were discovered by researchers from Russian antivirus vendor Doctor Web and were reported to Google last week. The researchers dubbed the new threat Android.Xiny.19.origin.

    Major desktop browsers push automatic security updates directly to users on a regular basis, so most users don’t have to worry about security updates. But Linux users are dependent on their distributions to release updates. Apple fixed over 100 vulnerabilities in WebKit last year, so getting updates out to users is critical.

Celebrating 15 Years of SELinux

Red Hat
Security

On Dec. 22, 2000, the NSA released their code to the wider open source world in the form of SELinux, and in doing so forever changed the security landscape of not just Linux, but the technology world at large. A combination of policies and security frameworks, SELinux is one of the most widely-used Linux security modules. Without these innovations, Common Criteria, a crucial government security certification, would likely not exist for Linux.

  • Migrating from Kali Linux 2 to Kali Linux 2016.1

    The first edition of Kali Linux Rolling, Kali 2016.1, was released more than a week ago. It marks the end of Kali Linux 2 and the beginning of a new release regime.

    It’s still based on Debian Testing, so existing users don’t have to do anything special but run a few commands to upgrade from Kali Linux 2 to Kali Linux 2016.1. Aside from installation images for the GNOME 3 desktop, there are also installation images for the Light edition, which uses the Xfce desktop environment. And there are also ARM installation images.

Lexumo Lands $4.89 Million Seed Round To Help Ensure Open Source Code Security

Security

What has Lexumo created to warrant that kind of financial attention? It indexed all of the open source code in the world and created a cloud security service aimed at helping companies using open source code inside embedded systems or enterprise software. These groups can submit their code to the Lexumo service and it checks for any known security vulnerabilities. What’s more, it will then continuously monitor the code for updates and inform developers when one is available.

  • Forcing out bugs with stress-ng

    I've also tried to make stress-ng portable, so it can build fine on GNU/Hurd and Debian kFreeBSD (with Linux specific tests not built-in of course). It also contains some architecture specific features, such as handling the data and instruction cache as well as the x86 rdrand instruction and cache line locking. If there are any ARM specific features than can be stressed I'd like to know and perhaps implement stressors for them.

  • OpenSSH and the dangers of unused code

    Unused code is untested code, which probably means that it harbors bugs—sometimes significant security bugs. That lesson has been reinforced by the recent OpenSSH "roaming" vulnerability. Leaving a half-finished feature only in the client side of the equation might seem harmless on a cursory glance but, of course, is not. Those who mean harm can run servers that "implement" the feature to tickle the unused code. Given that the OpenSSH project has a strong security focus (and track record), it is truly surprising that a blunder like this could slip through—and keep slipping through for roughly six years.

  • Getting RSS feeds for news websites that don’t provide them
    On the technical side, this seems to be one of the most stable pieces of software I ever wrote. It never crashed or otherwise failed since I started running it, and fortunately I also didn’t have to update the HTML parsing code yet because of website changes. It’s written in Haskell, using the Scotty web framework, Cereal serialization library for storing the history of the past articles, http-conduit for fetching the websites, and html-conduit for parsing the HTML. Overall a very pleasant experience, thanks to the language being very convenient to write and preventing most silly mistakes at compile-time, and the high quality of the libraries.
  • Quick Highlight
    Martin Blanchard put together a new “quick highlight” plugin for Builder this last week. It was a great example of how to submit a new feature, so I just wanted to highlight it here. Post to bugzilla, attach a patch, and we will review quickly and help with any additional integration that might be necessary.
