Beyond rigging batteries with a SEMTEX shell, the key vulnerability is a BMS (battery protection controller) that can be signaled to overheat/damage the battery and intentionally cause a fire.
With Israel supremacy firmly self justified on religious grounds, their solid control over US politics and deep state appointments, any obstacle to their genocidal solutions for supremacy is a target. US politicians (Trump specifically) congratulating Israel/Netanyahu on the brilliance of the tactic, means not just supporting assassinations of obstacles to Israel supremacy, but to Trump's supremacy, through strong arming industry partners to include the capability. One of the current AI powers is easily identifying the phones of those who are less enthusiastic of policies.
One way to make sure that all Americans are vulnerable to such an attack is "all accusations are confessions" a ban on Chinese phones accusing them of having the back door.
Disempowering the US empire is key to world not descending into murderous war, and embracing such weapons against humanity.
The natural alliance of any Asian country is with Chinese trade. Especially in tech, where Chinese market is 5x that of US, and Asian market larger than the hegemon colonial universe. Sure, countries want independence, but prosperity comes from peace and trade. The US has to spend a lot to "shit disturb" the region.
The best part of global trade is peace it provides. There is a limit to how aggressive the US can be to China, including its Taiwan proxy, before the US and Taiwan become useless to rest of world. But keeping tech out of China is like the drug trade. There exists a nominally respectful of US country willing to turn a blind eye to smuggling/cut outs, and US is forced to buy nominal respect. China also is heavily investing into a delete America program that will eventually achieve success/parity with Taiwan, and with Huawei, seems ahead of schedule.
