A major cyberattack has crippled the global networks of Stryker, one of the world’s largest medical device companies, with an Iran-linked hacking group claiming responsibility and warning it marks “the beginning of a new chapter in cyber warfare”.

Handala, a hacking persona with documented ties to Tehran, said it carried out the attack in retaliation for the killing of more than 170 people, most of them schoolgirls, in a strike on a school in the southern Iranian city of Minab on the first day of the US-Israeli military war against Iran.

The hacking group said it had seized 50 terabytes of company data, which it claimed was “now in the hands of the free people of the world.”

The outages began shortly after midnight on the US East Coast on Wednesday, knocking out Windows-based devices, including laptops and mobile phones, connected to Stryker’s systems.

1. And so it (asymmetric warfare) begins.

I doubt trump ever thought the Iranian people were little more than goat herders. There was massive recruitment to learn cyber warfare in Iran after a US-made virus (deployed by Mossad?) wrecked centrifuges processing uranium.

2. TSF gutted intelligence capabilities and experience with respect to cybersecurity and Iran. Seems

like they are inviting hacks. so they can go....to extremes in retaliation? Didn't want to say nuclear...

3. Stryker is one of companies that kept up operations in Russia post their invasion, so Iran...

Is inadvertantly poking Russia in the eye by having at them.

Given the Iranian penchant for attacking nominal allies and supporters though it could also have been intentional.

4. The many levels of retaliatory action by Iran were unexpected by the US.

The closing of shipping out oil from the Middle East, the attacks on US interests in the area, making storage and oil export facilities unsafe so they are closed down, and now disruptive cyberattacks.

Like any overconfident bully who expected his victim to go down and stay down after the first blow, Trump doesn't know what to do if the victim fights back.

Lessons learnt from Vietnam and Afghanistan were too soon forgotten.

5. What does Stryker do?

Every ambulance in the US has an ambulance cot -- most folks call it a stretcher. Almost 100% of these are Stryker products. Most ambulance services have gone to hydraulic, battery-powered cots that will raise and lower a patient who is up to 600 pounds. Stryker provides maintenance and spare parts. Stryker Power-Pro XT.

What if the patient is upstairs? Stryker makes a "stair chair" -- basically a wheel chair that can climb down stairs with a patient in it. Stryker services and maintains these.

Have you ever been in an ambulance, or, called 911 and had medics respond? In addition to a "jump bag" filled with medical supplies, one of the medics will be carrying what looks like a miniature TV set. The patient is attached to this device -- a LifePac -- to monitor blood pressure, oxygen saturation, pulse, and respiration. If need be the LifePac can take an EKG/ECG, print out a strip showing heart condition -- AFIB, VFIB, STEMI, etc. -- transmit that EKG/ECG strip to the ambulance wifi then to the ER. Cardiac arrest? The LifePac serves as a defibrillator that can shock the heart back into action. Severe heart arrythmia? LifePac does "cardiac pacing" -- it will get your heart back into rhythm. Who makes this marvelous device and its attachments along with servicing, calibrating, and maintaining the LifePac? Stryker, of course.

That bed you are in when you are in the hospital? Stryker -- sales, maintenance, service.

I could go on but you get the picture.

Why would Iran take down Stryker?
