My mind initially went to a government cover-up, but then:

> 27th of September 2025, The fire is believed to have been caused while replacing Lithium-ion batteries. The batteries were manufactured by LG, the parent company of LG Uplus (the one that got hacked by the APT).

Could the battery firmware have been sabotaged by the hacker to start the fire?

It could have.

But

replacing a UPS is usually done to right time pressures. the problem is, you can rarely de-energise UPS batteries before replacing them, you just need to be really careful when you do it.

Depending on the UPS, Bus bars can be a mother fucker to get on, and of they touch energised they tend to weld together.

With lead acid, its pretty bad (think molten metal and lots of acidic, toxic and explosive gas, with lithium, its just fire. lots of fire that is really really hard to put out.

Don't you have to put UPS's in bypass mode precisely for this reason while doing maintenance on them ?

this was a plot in a Mr. Robot episode, heh. Life imitating art?
