Exsparko-destructus! What happens when wand waving meets extremely poor wiring

Nifty Silver badge

I worked for a company that made process control systems. It was in the days of film cameras with a big electronic flash on top. The installation technician would start up the system for the first time with the processor cabinet doors open. Check that all processor lights were blinking rhythmically as expected. Check the SCADA graphics (and have a good listen to the factory noises) to see that all valves were in the correct position and motors off so that the system was 'at rest'. Now was the time, before locking up the cabinet, to take the photo that went into the project album. These were used by the salesmen or for reference before service techs went to a site.

Flash, then bang and wallop. All processor lights now frozen and valves and motors could be heard activating at random across the factory. Turns out the EMP from the cameras flash was enough to upset the processors so they crashed. One processor crashing was enough to corrupt the shared RAM so the others would crash. In the process, I/O sent signals that caused plant activations*. Normally the risk of this happening even in a lightning storm existed but was low, because the steel cabinet doors are kept locked.

Previous photography had been done the same way without crashes but there must have been a probability that every Nth photography flash would trigger a crash. The procedure was modified after that to ensure that the rack was powered down in the presence of a flash gun.

*For those worried about the implication that factory fires/explosions can occur if automation goes doolally, there were additional direct safety interlocks that override to (theoretically) prevent overfilling/over pressure, overheating, etc. But things can still require a lot of cleaning up and checking after an incident.

Kaseya obtains REvil decryptor, starts sharing it with afflicted customers

Re: Is there single key ?

Sounds like fairy dust or the ransomware was very low quality (which would contradict all the news stories we've heard about how professional the ransomware attacks were).

The idea that a decryptor can hold 'all the keys' is too fancyful. Must be more to the story.

I can walk past 10 local building extension projects where they've started but no discernable work has happened for 2 months. In some cases scaffolding has been up for months or part building framed leaning on a wall for 6 weeks. Either all builders are doing bait and hold, or there's a chronic shortage of materials.

Re: Can't wait...

"would plug their laptop directly into the internet and live in ignorant bliss with a woefully insecure setup"

It's a long while ago but when NTL first supplied broadband to my address, they supplied a long RJ45 terminated cable with it. Which I blissfully ran through the house and plugged straight into my PCs Ethernet socket. I was so blown away by the speed compared to dial up that I didn't have a thought about security. Can anyone remember if fully wired NTL even came with a router?

Later a second computer entered the household and I bought my first WiFi router (before NTL supplied them). While on the phone to NTL CS I was told that more than one device wasn't allowed on the home network, when I mentioned my router.

Everyone cites that 'bugs are 100x more expensive to fix in production' research, but the study might not even exist

Nifty Silver badge

Re: Equally unattributed, but different...

"50% more expensive to fix a bug at the coding stage than at the design stage, 10 times more expensive at the integration stage, 60 times more if it’s caught in alpha testing and 100 times as expensive to fix in customer beta test"

True for one group of products, but a huge generalisation there.

I worked with 2 products for comparison. One was data driven with a lot of configurability - quite variable in the way it could be used. The second has an built in programming language that everyday users could use with, so was not just configurable per config files and data driven but also programmable. The variability of usage was near infinite. I would say that genuine, full scenario and regression testing was near impossible. So instead, the approach was developed to provide powerful debugging and crash analysis tools for the real-time system. This was targeted at break/fix and not at the design stage.

How to keep your enterprise up to date by deploying the very latest malware

Nifty Silver badge

I used to keep my work laptop in the bedroom in a backpack. It would regularly wake up in the small hours, sometimes fan would run hard, laptop got very hot and occasionally it'd flatten the battery. On investigating the event viewer I discovered it was coming out of sleep mode to do updates. The BIOS seemed to be able to wake the machine on a schedule. It took some digging to disable this feature.

If I'd shut down instead of using sleep, the overnight updates would've been deferred until switch on (HDD in those days, 5min+ to boot up). I was baffled by the maintenance policy.

LibreOffice 7.2 release candidate reveals effort to be Microsoft-compatible

My confidence in LibreOffice was dented recently, as data was disappearing from column 1 in some rows. I'd repopulate the text and some days later the same would happen. Also had a case or two where Excel could not open a file but LibreOffice could (always .XLSX).

Looks just like https://ask.libreoffice.org/en/question/167450/i-lost-a-significant-amount-of-data-from-an-excel-spread-sheet-suddenly/

Due to helping son out with his new job I took a family sub of Office 365 so am using Excel again. When this sub ends in a years time it'll be back to LibreOffice, will see how reliable it is then.

And if these workers had been working at work, the crims wouldn't have been targeting them?

A secondary new vector would be BYOD at home. Again, where's the detail?

Re: Depressing

"Don't you end up with loads of very similar crash reports? Lots of duplication?"

The problem is that it can be the exact nature of the user data that causes the crash. The data is the scenario. I used to use a tool that could obfuscate such data while still allowing it to cause the same scenario crash in replication. With a bit of further development the tool could have been put into an automation sequence to ensure that only GDPR-compliant data left either the users server or a GDPR-compliant vault.

Re: I May Be Cheap...

Over 10 years ago I was at a UK tourist spot cafe with a group of Chinese tourists. One of them was using a Chinese based payment card. She was getting a text for every transaction no matter how trivial, showing amount paid. As it happened she had what seemed like a failed transaction at the till and was asked to repeat the payment. However her texts showed she now had 2 approved payments, she demanded and got a refund in the spot.

PayPal app can notify you of every transaction which is why I use it wherever possible for recurring payments. Its a disappointment that something similar isn't offered wth payment cards.

I was fortunate to get the full experience of on-boarding to a new company while working from home during Covid. The water-cooler and over-the-shoulder moments are missing. Now, with best intentions the boss did institute group activities as a replacement, typically fun quizzes and competitions online.

Problem is that both with the group activities and Slack chatting during daily work, the boss keeps a constant stopwatch on everyone's metrics. That kind of atmosphere makes genuine teamwork while working remotely quite a stressful thing. It takes me right back to one of my first jobs where the boss used to patrol the cubicles and comment pointedly if he saw anyone chatting with colleagues...

Re: Much cheaper.

Yes you can compare WFH here with WFH there.

Now, UK managers are already having a mind-struggle with UK based WFH workers that used to be office based, never mind Croatia based ones. And a legal payroll mechanism is needed for say, Croatia.

The real corporate dream is move whole departments including the 'prep monitor' to Eastern Europe or maybe even India at a fraction of the wage bill. In this case the manager himself may experience an existential crisis.

The WFH-only comparison works where there's a compelling use-case, i.e. employing experienced specialists with a massive track record. That's usually developers or consultants.

In your case it looks like you're exceptionally confident and nimble and have solved the payment/EU employment regs issues.

Re: Much cheaper.

'My company can employ three IT guys WFH in Croatia for the price of one IT guy WFH in England'

Yes it looks good on the surface and I think that are consultants earning fees by 'selling; how much money an organisation can save. Reality is that salaries are rising at easily 10% pa for just this reason. I've seen the situation where once the employment centre has moved to Eastern Europe it's a struggle to retain anyone for more than 18 months. And some vacancies stay permanently open.

I've also been in interviews where the manager frankly admitted that he'd been trying to hire in Eastern Europe but could not find the speciality he wanted. Kudos for honesty there.

Oh and BTW - what has WFH really got to do with it?

Re: Leasehold, fleecehold

You do.

The property owners each own a share of the freehold

Only in the *rare* case where the flat owners own the freehold. Freehold is normally owned by a company that specialises in returning shareholder value by extorting fees for any changes to the building, change of tenant and maybe there's something to be creamed off the buildings insurance.

Service charges go to a separate management company and these are for maintenance only, not upgrades. New roof = maintenance. Upgrade fire safety = a bill to be split among the leaseholders.

Cityfibre plumbed fibre into every floors hallway in a block where I let a flat. The building management seemed unaware it had happened when I emailed them to ask about it - I only found out when the tenant found his address was on Cityfibre's coverage list and he asked my permission holes to be drilled and for the router to be installed. The current tenant is enjoying the service. The fibre only goes as far as the public hallway and the last few metres to router are coax or CAT5 (I haven't been to look). So, not real FTTP then, is it not much different from Virgin Media?
