Security: BGP Hijack Factory, IDN, Microsoft Windows Back Doors and Intel Defects

  • Shutting down the BGP Hijack Factory

    It started with a lengthy email to the NANOG mailing list on 25 June 2018: independent security researcher Ronald Guilmette detailed the suspicious routing activities of a company called Bitcanal, whom he referred to as a “Hijack Factory.” In his post, Ronald detailed some of the Portuguese company’s most recent BGP hijacks and asked the question: why Bitcanal’s transit providers continue to carry its BGP hijacked routes on to the global [I]nternet?

    This email kicked off a discussion that led to a concerted effort to kick this bad actor, who has hijacked with impunity for many years, off the [I]nternet.

  • Malformed Internationalized Domain Name (IDN) Leads to Discovery of Vulnerability in IDN Libraries

    The Punycode decoder is an implementation of the algorithm described in section 6.2 of RFC 3492. As it walks the input string, the Punycode decoder fills the output array with decoded code point values. The output array itself is typed to hold unsigned 32-bit integers while the Unicode code point space fits within 21 bits. This leaves a remainder of 11 unused bits that can result in the production of invalid Unicode code points if accidentally set. The vulnerability is enabled by the lack of a sanity check to ensure decoded code points are less than the Unicode code point maximum of 0x10FFFF. As such, for offending input, unchecked decoded values are copied directly to the output array and returned to the caller.

  • GandCrab ransomware adds NSA tools for faster spreading

    "It no longer needs a C2 server (it can operate in airgapped environments, for example) and it now spreads via an SMB exploit -- including on XP and Windows Server 2003 (along with modern operating systems)," Beaumont wrote in a blog post. "As far as I'm aware, this is the first ransomware true worm which spreads to XP and 2003 -- you may remember much press coverage and speculation about WannaCry and XP, but the reality was the NSA SMB exploit (EternalBlue.exe) never worked against XP targets out of the box."

  • Intel Discloses New Spectre Flaws, Pays Researchers $100K

    Intel disclosed a series of vulnerabilities on July 10, including new variants of the Spectre vulnerability the company has been dealing with since January.

    Two new Spectre variants were discovered by security researchers Vladimir Kiriansky and Carl Waldspurger, who detailed their findings in a publicly released research paper tilted, "Speculative Buffer Overflows: Attacks and Defenses."

    "We introduce Spectre1.1, a new Spectre-v1 variant that leverages speculative stores to create speculative buffer over-flows," the researchers wrote. "We also present Spectre 1.2 on CPUs that do not enforce read/write protections, speculative stores can overwrite read-only data and code pointers to breach sandboxes."

  • First results of the ROSIN project: Robotics Open-Source Software for Industry
    Open-Source Software for robots is a de-facto standard in academia, and its advantages can benefit industrial applications as well. The worldwide ROS-Industrial initiative has been using ROS, the Robot Operating System, to this end. In order to consolidate Europe’s expertise in advanced manufacturing, the H2020 project ROSIN supports EU’s strong role within ROS-Industrial. It will achieve this goal through three main actions on ROS: ensuring industrial-grade software quality; promoting new business-relevant applications through so-called Focused Technical Projects (FTPs); supporting educational activities for students and industry professionals on the one side conducting ROS-I trainings as well as and MOOCs and on the other hand by supporting education at third parties via Education Projects (EPs).
  • Baidu To Launch World’s First Intelligent Vehicle Infrastructure Cooperative Systems Open Source Solution By End Of 2018
    Baidu Inc. has announced it will launch the Apollo Intelligent Vehicle Infrastructure Cooperative Systems (IVICS) open-source solution by the end of 2018, leveraging its capabilities in autonomous driving to bring together intelligent vehicles and infrastructure to form a “human-vehicle-roadway” interplay – an important step toward developing future intelligent transportation.
  • Versity Open Sources Next Generation Archiving Filesystem
    The ScoutFS project was started in 2016 to address the rapidly growing demand for larger POSIX namespaces and faster metadata processing. The design goal for ScoutFS includes the ability to store up to one trillion files in a single namespace by efficiently distributing metadata handling across a scale out cluster of commodity compute nodes.

  • Epic Clock Clocks The Unix Epoch
    Admit it: when you first heard of the concept of the Unix Epoch, you sat down with a calculator to see when exactly 2³¹-1 seconds would be from midnight UTC on January 1, 1970. Personally, I did that math right around the time my company hired contractors to put “Y2K Suspect” stickers on every piece of equipment that looked like it might have a computer in it, so the fact that the big day would come sometime in 2038 was both comforting and terrifying. [Forklift] is similarly entranced by the idea of the Unix Epoch and built a clock to display it, at least for the next 20 years or so. Accommodating the eventual maximum value of 2,147,483,647, plus the more practical ISO-8601 format, required a few more digits than the usual clock – sixteen to be exact. The blue seven-segment displays make an impression in the sleek wooden case, about which there is sadly no detail in the build log. But the internals are well documented, and include a GPS module and an RTC. The clock parses the NMEA time string from the satellites and syncs the RTC. There’s a brief video below of the clock in action.
  • 3 top Python libraries for data science
    Python's many attractions—such as efficiency, code readability, and speed—have made it the go-to programming language for data science enthusiasts. Python is usually the preferred choice for data scientists and machine learning experts who want to escalate the functionalities of their applications. (For example, Andrey Bulezyuk used the Python programming language to create an amazing machine learning application.) Because of its extensive usage, Python has a huge number of libraries that make it easier for data scientists to complete complicated tasks without many coding hassles. Here are the top 3 Python libraries for data science; check them out if you want to kickstart your career in the field.
  • PortableCL 1.2 Still Coming While POCL 1.3 Will Further Improve Open-Source OpenCL
    It's been a number of months since last having any major news to report on POCL, the "PortableCL" project providing a portable OpenCL/compute implementation that can run on CPUs, select GPUs, and other accelerators. POCL 1.1 from March remains the current stable release while POCL 1.2 has been in the release candidate stage. The POCL 1.2 release candidates began last month with a few highlights like LLVM 7.0 support, device-side printf support, and HWLOC 2.0 library support.

New CloudBees Suite Addresses DevOps Gaps in Software Delivery

CloudBees is bringing a set of products into a new CloudBees Suite that it said will help companies of all sizes streamline the software development process. The new software is set to be announced Sept. 18 at the company’s DevOps World / Jenkins World conference in San Francisco. Jenkins is the open-source version of CloudBees, which is a commercial offering. A central piece of the CloudBees Suite is the CloudBees Core for unified governance of continuous delivery operations and processes used in DevOps. Software pipelines can also use Core to run software pipelines more efficiently in a self-managed way in the cloud or on-premises.
