Several U.S. government agencies warned that unidentified
hackers are trying to breach devices made by Siemens that
are used to monitor and operate water facilities and ‌other
critical infrastructure systems, according ​to a cybersecurity
advisory published Wednesday.

The warning comes amid widespread cyber incidents targeting
local ⁠water systems in multiple states in recent ​weeks in
attacks cybersecurity experts suspect are linked to ⁠Iran.

The advisory describes an "active threat" to all Siemens S7
Series programmable logic controllers across multiple
critical infrastructure sectors, including ‌manufacturing,
energy, water, and wastewater, chemical, food ​and
agriculture facilities, according ‌to the warning issued by
the National Security Agency, FBI, ‌Department of Energy,
Environmental Protection Agency, and the Department of
Homeland Security's Cybersecurity and Infrastructure
Security ⁠Agency.

   PLAs are kinda stupid - so really it's likely the
   software kit used to program/check the things.
   LIKELY the affected sites kept all that ONLINE
   so they could over-work ONE geek rather than
   pay to have their own.

   In an irony - the early Iranian nuke program used
   Siemens controllers on its uranium centrifuges.
   The spooks found a vulnerability and caused the
   devices to destroy themselves. Set 'em back a
   few years.

   For obvious reasons nobody is going to EXACTLY
   identify how the things were hacked. However
   Siemens is a major supplier of industrial
   process controllers, so everybody had better
   keep an eye out.
