Microsoft To Open-Source Windows Security-Testing Tool
by Lawrence D'Oliveiro 16 Sep '20

16 Sep '20

Ever wondered how Microsoft manages to keep Windows so secure? You won’t have to wonder for much longer, as it is planning to open-source OneFuzz <https://www.theregister.com/2020/09/16/microsoft_open_sources_fuzzing_tool/>, a key tool it uses to probe its OS for vulnerabilities. Yes, third-party developers! Soon you, too, will be able to achieve truly Microsoftian levels of code quality!

Microsoft Submits Linux Kernel Patches For a 'Complete Virtualization Stack' With Linux and Hyper-V
by Peter Reutemann 16 Sep '20

16 Sep '20

'Microsoft has submitted a series of patches to the Linux kernel with its aim being "to create a complete virtualization stack with Linux and Microsoft Hypervisor." The Register reports: The patches are designated "RFC" (Request for comments) and are a minimal implementation presented for discussion. The key change is that with the patched kernel, Linux will run as the Hyper-V root partition. In the Hyper-V architecture, the root partition has direct access to hardware and creates child partitions for the VMs it hosts. "Just think of it like Xen's Dom0," said Microsoft principal software engineer Wei Liu. Hyper-V's architecture is more similar to Xen than it is to KVM or to VMware's ESXi, and Liu acknowledged that "we drew inspiration from the Xen code in Linux," specifically for code handing interrupts. Until now, the Hyper-V root partition had to run Windows. Microsoft has also ported Intel's open-source Cloud Hypervisor, a Virtual Machine Monitor (VMM) written in Rust that normally runs on KVM, the hypervisor that is built into the Linux kernel. Cloud Hypervisor itself is currently in "very early pre-alpha stage." Even when Linux is the root partition, it will still run on top of Microsoft's hypervisor, a thin layer running with ring -1 privileges. It will no longer be necessary to run Windows on that hypervisor, though, enabling Microsoft to call the new arrangement "a complete virtualization stack with Linux."' -- source: https://linux.slashdot.org/story/20/09/15/207219 Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, NZ +64 (7) 858-5174 http://www.cms.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

New Windows exploit lets you instantly become admin. Have you patched?
by Peter Reutemann 16 Sep '20

16 Sep '20

'Researchers have developed and published a proof-of-concept exploit for a recently patched Windows vulnerability that can allow access to an organization’s crown jewels—the Active Directory domain controllers that act as an all-powerful gatekeeper for all machines connected to a network. CVE-2020-1472, as the vulnerability is tracked, carries a critical severity rating from Microsoft as well as a maximum of 10 under the Common Vulnerability Scoring System. Exploits require that an attacker already have a foothold inside a targeted network, either as an unprivileged insider or through the compromise of a connected device.' -- source: https://arstechnica.com/information-technology/2020/09/new-windows-exploit-… Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, NZ +64 (7) 858-5174 http://www.cms.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

European Police Malware Could Harvest GPS, Messages, Passwords, More
by Peter Reutemann 16 Sep '20

16 Sep '20

'The malware that French law enforcement deployed en masse onto Encrochat devices, a large encrypted phone network using Android phones, had the capability to harvest "all data stored within the device," and was expected to include chat messages, geolocation data, usernames, passwords, and more, according to a document obtained by Motherboard. From the report: The document adds more specifics around the law enforcement hack and subsequent takedown of Encrochat earlier this year. Organized crime groups across Europe and the rest of the world heavily used the network before its seizure, in many cases to facilitate large scale drug trafficking. The operation is one of, if not the, largest law enforcement mass hacking operation to date, with investigators obtaining more than a hundred million encrypted messages. "The NCA has been collaborating with the Gendarmerie on Encrochat for over 18 months, as the servers are hosted in France. The ultimate objective of this collaboration has been to identify and exploit any vulnerability in the service to obtain content," the document reads, referring to both the UK's National Crime Agency and one of the national police forces of France. As well as the geolocation, chat messages, and passwords, the law enforcement malware also told infected Encrochat devices to provide a list of WiFi access points near the device, the document reads.' -- source: https://yro.slashdot.org/story/20/09/15/1517203 Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, NZ +64 (7) 858-5174 http://www.cms.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

Nvidia To Buy ARM
by Lawrence D'Oliveiro 15 Sep '20

15 Sep '20

So, SoftBank has found a buyer for ARM, and it’s graphics-card maker Nvidia <https://www.theregister.com/2020/09/14/nvida_arm_acquisition/>. The price is US$40 billion, including US$12 billion in cash. NVidia promises to maintain the open licensing model, and promises to “turbocharge” it with its own R&D resources. SoftBank makes a modest profit on the deal.

Australian Cyber Security Centre Recommends Not Paying Ransomware
by Lawrence D'Oliveiro 13 Sep '20

13 Sep '20

From <https://www.theregister.com/2020/09/12/follow_security_basics_and_you/>: Paying a ransom does not guarantee decryption of data. Open source reporting indicates several instances where an entity paid the ransom but the keys to decrypt the data were not provided. The ACSC has also seen cases where the ransom was paid, the decryption keys were provided, but the adversary came back a few months later and deployed ransomware again. The likelihood that an Australian [organisation] will be retargeted increases with every successful ransom payment. ...

DPL: Debian Project Has Plenty Of Money But Not Enough Developers
by Lawrence D'Oliveiro 11 Sep '20

11 Sep '20

A report <https://www.theregister.com/2020/09/10/debian_project_address/> by the current Debian Project Leader, Jonathan Carter, on the current state of the Mother Of All Linux Distros. They are not short of funds, but they have too few project contributors trying to do too much: The culture of the community is not to spend money unnecessarily. “Debianites don’t like spending money,” he said. “They feel guilty.” It’s probably also the largest Linux distro: In 2009, there were 22,000 binary packages for the i386 architecture in Lenny, the current release at the time. Today there are over 61,000 amd64 binary packages in Bullseye, the forthcoming release. After Bullseye, “100,000 packages is a serious reality on the horizon,” he said. I like this quote: “Debian is a bottomless pit of problems. It’s inherent in the work we do. We’re affected by nearly every problem that exists in the realm of computer science.” How about that for the ultimate geek brag? 🐧

Some Of Our Open-Access Journals Are Missing
by Lawrence D'Oliveiro 11 Sep '20

11 Sep '20

“Open-Access” scientific journals make research papers available online for free. They have become popular as awareness has spread of the practices of traditional publishers like Elsevier, which charge research groups to publish their papers in journals, and then charge hefty subscription fees to those same groups, and all the rest of their customers, for copies of those journals. And then claiming copyright on those papers, on top of it. (And what about the parties the providing the most expensive part of the publication service, namely the fellow researchers doing the peer review? Nope, they don’t get any payment for this at all.) However, this does make the financial model of these Open-Access journals a bit precarious. And perhaps it’s not too surprising that several of them have disappeared since their founding. Operations like the Internet Archive do have the resources to grab copies of their content before they do, but it helps to be aware that these sorts of sites are particularly vulnerable to vanishing. <https://www.theregister.com/2020/09/10/open_access_journal/>

System76’s Lemur Pro: A powerful, ultralight OEM Linux laptop
by Peter Reutemann 11 Sep '20

11 Sep '20

'System76's Lemur Pro is a 14.1-inch, lightweight powerhouse of an OEM Linux laptop, with an attractive black-finished magnesium-aluminum alloy chassis. If you're looking for a laptop that gets the occasional jealous look at coffee shops (or technical conferences), the Lemur Pro will not disappoint. As configured at $1,563, the Lemur Pro is not a cheap laptop—but it doesn't look, feel, or perform like one, either. The Intel Comet Lake CPU wouldn't be our first choice if we designed a laptop from scratch, but as an entire system, it's hard to find much fault with the Lemur Pro—particularly when limiting the field to OEM Linux laptops alone.' -- source: https://arstechnica.com/gadgets/2020/09/system76s-lemur-pro-a-powerful-ultr… Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, NZ +64 (7) 858-5174 http://www.cms.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/
