Security: Meltdown, Equifax, IOC's Microsoft Experience

-
Meltdown fix could kill your Linux experience by 8,000 per cent, says Netflix [Ed: And of course the hypothetical worst case scenarios become headlines...]
Brendan Gregg, who is part of the team that ensures that Netflix performs as planned, says that the Linux fix causes a huge strain on the CPU leading to the "largest kernel performance regressions I've ever seen".
The technique is called Kernel Page Table Isolation (KPTI) and does pretty much what it says - it makes sure that the page tables for users are different for the ones used by the machine.

'Olympic Destroyer' Malware Hit Pyeongchang Ahead of Opening Ceremony
Talos points out that Olympic Destroyer's disruptive tactics and spreading methods resemble NotPetya and BadRabbit, two pieces of Ukraine-targeting malware seen in the last year that the Ukrainian government, the CIA, and other security firms have all tied to Russian hackers [sic].

What is Olympic Destroyer? Malicious file-wiping malware hits Pyeongchang to embarrass organisers [iophk: "IOC invites this kind of trouble by spreading Windows throughout the org"]
It then deletes all shadow copies on the system and then uses wbadmin.exe to destroy all system files "to ensure that file recovery is not trivial". The malware also uses a tool called bcdedit to make sure that the Windows recovery console cannot attempt to repair anything on the host making sure recovery is "extremely difficult".

You can now download zchunk metadata in Rawhide
It’s been a year since I first started working on zchunk, and I’m excited that we’ve finally managed to get it fully integrated into Fedora’s metadata. I’d like to take the opportunity to express my appreciation to Daniel Mach, Jaroslav Mracek and the rest of the DNF team for reviewing and merging my (quite invasive) patches, Michael Schroeder for extensive critiques and improvements on the zchunk format, Igor Gnatenko for help early on, and, finally, Neal Gompa for working behind the scenes to keep things moving.

i.MX8M Mini based handheld dev kit has dual Linux BSPs
Solectrix is prepping an “SX Mobile Device Kit” for developing handhelds with Debian and Yocto Linux BSPs, an i.MX8M Mini SoC, an optional 5-inch touchscreen, WiFi, BT, GNSS, and mini-PCIe, and features for prototyping CSI-2 camera sensors.
These days we rarely cover mobile computers, most of which are rugged field-service handhelds that run Android, such as Two Technologies’ N5Print. Yet, Solectrix’s SX Mobile Device Kit (MDK) seemed of particular interest since it’s a development kit with Linux BSPs and NXP’s new i.MX8M Mini SoC.
In addition, a Solectrix GmbH rep informed us that optional features like GbE and USB Type-A host and GbE ports enable the MDK to be used as a general-purpose embedded development board. Purchase options range from buying the 125 x 78mm PCB by itself all the way up to a fully equipped handheld with a 5-inch screen. Yocto Project and Debian Linux BSPs are available, and the board also supports Android 9 Pie.
