Keyfactor has partnered with IBM Consulting to enable organizations to accelerate adoption of post-quantum cryptography (PQC) before existing legacy encryption schemes might be cracked later this decade. Under the terms of the non-exclusive alliance, the cryptographic discovery, public key infrastructure (PKI), digital signage and certificate lifecycle automation tools and platforms provided by Keyfactor will be..
The post Keyfactor Allies with IBM Consulting to Spur PQC Adoption appeared first on Security Boulevard.
Virtualisation is a lot older than you might think, with (one of?) the first implementation(s) being IBMβs VM/CMS, the line of operating systems that would grow to include things like System/370, System/390, all the way up until IBM/Z, which is still being developed and sold today; only recently IBM released the IBM z17 and z/OS 3.2, after all.
The VM series of operating systems is designed exclusively for mainframes, and works by giving every user their own dedicated virtual machine running on top of the Control Program, the hypervisor. Inside this virtual machine the user can run a wide variety of operating systems, from the simple, single-user classics like IBMβs Conversational Monitor System, to more complex systems like Linux or AIX.
Early versions of VM were released as open source and are now in the public domain, and enthusiasts have continued to build upon it and expand it, with the latest incarnations being the VM/370 Community Edition releases. They contain the Control Program and Conversational Monitor System, augmented by various fixes, improvements, and other additions. You can run VM in an emulator like Hercules, and continue on from there β but what, exactly, can you do with it?
Thatβs where Fun things to do with your VM/370 machine comes in. This article will give you an introduction to the system, and a number of first and later steps you can take while exploring this probably alien environment. If youβve always dreamt of using an early IBM mainframe, this is probably the easiest way to do so, because buying one is a really, really bad idea.

Some people not only have a very particular set of skills, but also a very particular set of interests that happen to align with those skills perfectly. When several unidentified and mysterious IBM PC ROM chips from the 1980s were discovered on eBay, two particular chipsβ dumped contents posed particularly troublesome to identify.
In 1985, theΒ
FChΒ model byte could only mean the 5170 (PC/AT),Β and the even/odd byte interleaving does point at a 16-bit bus. But there are three known versions of the PC/AT BIOS released during the 5170 familyβs lifetime, corresponding to the three AT motherboard types. This one here is clearly not one of them: its date stamps and part numbers donβt match, and the actual contents are substantially different besides.My first thought was that this may have come from one of those more shadowy members of the 5170 family: perhaps the AT/370, the 3270 AT/G(X), or the rack-mounted 7532 Industrial AT. But known examples of those carry the same firmware sets as the plain old 5170, so their BIOS extensions (if any) came in the shape of extra adapter ROMs. WhateverΒ thisΒ thing was β some other 5170-type machine, a prototype, or even just a custom patch β it seemed Iβd have to inquire within for any further clues.

Iβll be honest and state that most of the in-depth analysis of the code dumped from the ROM chips is far too complex for me to follow, but that doesnβt make the story it tells any less interesting. Thereβs no definitive, 100% conclusive answer at the end, but the available evidence collected by VileR does make a very strong case for a very specific, mysterious variant of the IBM PC being the likely source of the ROMs.
