  • Hacking Team’s Leak Helped Researchers Hunt Down a Zero-Day

    The vulnerability, which Microsoft called “critical” in a patch released to customers on Tuesday, would allow an attacker to infect your system after getting you to visit a malicious website where the exploit resides—usually through a phishing email that tricks you into clicking on a malicious link. The attack works with all of the top browsers except Chrome—but only because Google removed support for the Silverlight plug-in in its Chrome browser in 2014.

    [...]

    In July 2015, a hacker known only as “Phineas Fisher” targeted the Italian surveillance firm Hacking Team and stole some 400 GB of the company’s data, including internal emails, which he dumped online. The hack exposed the company’s business practices, but it also revealed the business of zero-day sellers who were trying to market their exploits to Hacking Team. The controversial surveillance firm, which sells its software to law enforcement and intelligence agencies around the world—including to oppressive regimes like Sudan, Bahrain, and Saudi Arabia—uses zero-day exploits to help sneak its surveillance tools onto targeted systems.

  • Flexible, secure SSH with DNSSEC

    With version 6.2 of OpenSSH came a feature that allows the remote host to retrieve a public key in a customised way, instead of the typical authorized_keys file in the ~/.ssh/ directory. For example, you can gather the keys of a group of users that require access to a number of machines on a single server (for example, an LDAP server), and have all the hosts query that server when they need the public key of the user attempting to log in. This saves a lot of editing of authorized_keys files on each and every host. The downside is that it's necessary to trust the source these hosts retrieve public keys from. An LDAP server on a private network is probably trustworthy (when looked after properly) but for hosts running in the cloud, that’s not really practical.

  • Server Hardening

    Server hardening. The very words conjure up images of tempering soft steel into an unbreakable blade, or taking soft clay and firing it in a kiln, producing a hardened vessel that will last many years. Indeed, server hardening is very much like that. Putting an unprotected server out on the Internet is like putting chum in the ocean water you are swimming in—it won't be long and you'll have a lot of excited sharks circling you, and the outcome is unlikely to be good. Everyone knows it, but sometimes under the pressure of deadlines, not to mention the inevitable push from the business interests to prioritize those things with more immediate visibility and that add to the bottom line, it can be difficult to keep up with even what threats you need to mitigate, much less the best techniques to use to do so. This is how corners get cut—corners that increase our risk of catastrophe.

  • How To Patch and Protect OpenSSH Client Vulnerability CVE-2016-0777 and CVE-2016-0778 [ 14/Jan/2016 ]

    The OpenSSH project released an ssh client bug info that can leak private keys to malicious servers. A man-in-the-middle kind of attack identified and fixed in OpenSSH are dubbed CVE-2016-0777 and CVE-2016-0778. How do I fix OpenSSH's client vulnerability on a Linux or Unix-like operating system?

OpenSSH vulnerability could expose private credentials

Security

So what exactly does this announcement mean? Since OpenSSH client version 5.4, there has been a feature called roaming that allows the client to resume a session that has been interrupted. Both the server and client would need to support roaming for this to work.

Server support was never added, but the feature is on by default for OpenSSH clients up to version 7.1p2. There are two vulnerabilities that stem from this feature and could be exploited when a user connects to an “evil” SSH server.

  • Trend Micro: Internet scum grab Let's Encrypt certs to shield malware

    It was inevitable. Trend Micro says it has spotted crooks abusing the free Let's Encrypt certificate system to smuggle malware onto computers.

    The security biz's fraud bod Joseph Chen noticed the caper on December 21. Folks in Japan visited a website that served up malware over encrypted HTTPS using a Let's Encrypt-issued cert. The site used the Angler Exploit Kit to infect their machines with the software nasty, which is designed to raid their online bank accounts.

  • The Mysterious Case of CVE-2016-0034: the hunt for a Microsoft Silverlight 0-day [Ed: back door?]

    Perhaps one of the most explosively discussed subjects of 2015 was the compromise and data dump of Hacking Team, the infamous Italian spyware company.

    For those who are not familiar with the subject, Hacking Team was founded in 2003 and specialized in selling spyware and surveillance tools to governments and law enforcement agencies. On July 5, 2015, a large amount of data from the company was leaked to the Internet with a hacker known as “Phineas Fisher” claiming responsibility for the breach. Previously, “Phineas Fisher” did a similar attack against Gamma International, another company in the spyware/surveillance business.

It is comprised of, mainly, three different entities — NFV Orchestrator, VNF Manager and Virtual Infrastructure Manager (VIM). The figure below highlights the MANO part of the ETSI NFV architecture.
  • After the hype: Where containers make sense for IT organizations
    Container software and its related technologies are on fire, winning the hearts and minds of thousands of developers and catching the attention of hundreds of enterprises, as evidenced by the huge number of attendees at this week’s DockerCon 2016 event. The big tech companies are going all in. Google, IBM, Microsoft and many others were out in full force at DockerCon, scrambling to demonstrate how they’re investing in and supporting containers. Recent surveys indicate that container adoption is surging, with legions of users reporting they’re ready to take the next step and move from testing to production. Such is the popularity of containers that SiliconANGLE founder and theCUBE host John Furrier was prompted to proclaim that, thanks to containers, “DevOps is now mainstream.” That will change the game for those who invest in containers while causing “a world of hurt” for those who have yet to adapt, Furrier said.

Industrial SBC builds on Raspberry Pi Compute Module

On Kickstarter, a “MyPi” industrial SBC using the RPi Compute Module offers a mini-PCIe slot, serial port, wide-range power, and modular expansion. You might wonder why in 2016 someone would introduce a sandwich-style single board computer built around the aging, ARM11 based COM version of the original Raspberry Pi, the Raspberry Pi Compute Module. First off, there are still plenty of industrial applications that don’t need much CPU horsepower, and second, the Compute Module is still the only COM based on Raspberry Pi hardware, although the cheaper, somewhat COM-like Raspberry Pi Zero, which has the same 700MHz processor, comes close.
