Don't rush to adopt QUIC – it's a slog to make it faster than TCP

storner
Boffin

Patience, my dear

TCP has evolved over some 40-50 years. I suppose QUIC will eventually deliver on their performance promises, but sure isn't going to be a simple quic-fix ;-)

Sysadmins: Why not simply verify there's no backdoor in every program you install, and thus avoid any cyber-drama?

storner

Focus on detection, not prevention

Requiring that normal software customers must verify the integrity of software distributed via official channels is completely impossible.

Get some detection systems instead and keep an eye out for behaviour that indicates a compromise. That will catch not only supplychain attacks, but also any other kind of attack.

Greenland's elections just bolstered China's tech world domination plan

Indeed. And greenlanders - including the winning IA party - really would like to separate from Denmark and gain independence. That costs a lot, so at some point they'll have to decide between independence and mining, or remaining part of the Kingdom of Denmark and keeping the RME's buried beneath Kvanefjell.

But keeping the chinese out of the loop would probably be a good idea.

Oh the joys of data formats

Somewhat along the lines of this story...

Every danish citizen has a unique identity-number issued at birth. System was designed in the 1960's, so obviously had to carefully consider how much data to store - meaning they ended up with a number including the date of birth in the DDMMYY format: DDMMYY-NNNN, the last 4 digits being a sequence number.

Except it wasn't quite a sequence number, because some bright fellow decided that it would be nice to distinguish between men and women, so the last digit is odd for men and even for women. (You can guess how the transgenders feel about that). Another bright fellow discovered that in 1960 they actually had grandparents born in the 1800's, so the first digit of the sequence number was used to encode the century: 0-4 if you were born in the 1900's, and 5-9 for the old people from the 1800's. Guess how that worked once year 2000 turned up, and we still had some people alive from the 1800's.

As the final twist, the sequence number also acted as a checksum of the entire identity number, with each digit multiplied by a specific factor, added together, and the sum had to be divisible by 11. Bizarre, and with the additional "feature" that you can only have about 250 people born on any one day. This wasn't really a problem until people started arriving from countries where you really don't care much about when you were born, so a third bright fellow decided that if the date of birth was unknown, assume Jan 1st of a year that seems plausible. Guess what happened when a surge of asylum seekers arrived one day...

So the checksumming was abandoned. But the identity number is used by every single public and private sector business, so quite a bit of scrambling when they had to remove that check from the customer entry forms.

Public sector IT disasters - you cannot make them up, they are for real.

Re: Hang on...

First exploit requires that you are admin on a CLIENT machine running off the VMware host. It gives you control of the VMware host, so it is a break-out from the virtual machine to the host.

Second exploit raises your privileges on the host machine to admin.

Re: One good thing about cheques

Cheques? How quaint ...

Banks here (Denmark) stopped accepting cheques for payment a couple of years ago. Nowadays, gift cards from shops are issued as credit cards. If you want to transfer cash we use cell phones and telephone numbers (not bank account numbers). We haven't gone all cash-less yet, but we're getting there. The Virus has sped things up somewhat, even among the greybeards.

Re: IP6 is the second thing I turn off

Remember that even if you are on a pure IPv4-only network, your systems will automatically get a link-local network address, and therefore can be exploited from a neighbour machine on the same LAN.

Re: 30 Years Ago

Usenet existed more than 30 years ago. Tiny pictures were posted on alt.sex.pictures in uuencoded form split into multiple posts because the size of posts was limited to a few kB (yes, KILO bytes, not MB), so you had to download each post, strip off the headers and run it through uudecode before viewing a tiny 200x140 pixel image on your 640x480 16-color CGA screen.
