This weekend, Israeli Defense Forces (IDF) launched an airstrike at Hamas's Cyber HQ in an apparently first of its kind real-time physical response by a nation state targeting the source of a cyber attack (as far as we know).
The Israel Defense Forces (IDF) has launched a physical attack on Hamas in response to an alleged cyber attack. A strike launched by Israeli forces targeted a building in the Gaza Strip that was hosting Hamas cyber army.
The IDF adopted a hybrid approach, it first stopped the cyber attack carried out by Hamas, then once it [had] localized the source of the offensive launched an airstrike.
This is simultaneously an evolution in hybrid-warfare and a return to levels of physical violence in the conflict between Hamas and Israel that hasn't been seen for five years.
The United States has reserved the right to retaliate similarly against cyber attacks since 2011, but has not done so.
The US had considered kinetic responses to a cyber attack:
State-backed hacking and physical warfare have been on a slow but steady path toward convergence for about two decades, and both information security and warfare researchers say that it was only a matter of time before a nation launched a kinetic attack against enemy hackers. "When I joined the very first Cyber Command in April 1999, we were talking about that as a serious thing in case it was needed," says Jason Healey, a former staffer in the George W. Bush White House and current cyberconflict researcher at Columbia University. "I wouldn't say we necessarily had plans for it, but we were thinking it through."
That's an expensive wrench

Since when is an indirect mode allowed with the x register?

Well, in my experience, since the 6809, way back in the late 1970's.
Also the Y register (X #2), the S (stack pointer) register, and the U register (S #2.)
In the following, [] indicates indirect addressing. So for instance:
If X=45, LDA [45,X] went to address 90, grabbed the 16-bit value there, used it as the fetch address, and moved what was in the location that pointed at into the A register.
All four pointer registers could be used as index registers, but the two stack pointers had comprehensive push and pull operators, so they were a bit stronger. Otherwise, nearly perfectly orthogonal.
Four pointers, CC register, 8-bit A and B accumulators, which could combine to be a single 16-bit accumulator, and a direct page register that could do 8-bit addressing of any of the 256 pages 00-FF in the 64k space. A truly great CPU for its day.
Lots more indirect modes, too... that just scratches the surface.
Also, the exact ASM syntax depended upon the particular assembler you were (or are) using.
You can play with the 6809 [datapipe-blackbeltsystems.com] using my comprehensive and quick emulation if you are running Windows or a Windows VM. Complete with assemblers, editors, and more. Full virtual disk system, FLEX09 disk OS, etc.

Orthogonal you say? Must have been nice. Poor 6502 coders were allowed to have LDA [45,x] but not LDY [45,x] or even STX $C000,y.

The 6809 had every flavor of addressing it needed for any pointer register to do its various kinds of addressing with any other register, stack ops excepted (those were available with the S and U registers only as above.) It was a joy to program. Such a shame that it was the end of its line. I always thought the 68000 was, while wider, a pale shadow of the 6809. I wrote a lot of assembler for both.
The 6809 was Motorola's last random-logic design, quite complex for its day. I imagine if Motorola's microcoders even considered making a MC-driven version of it, they probably ran away screaming. 😊
