"Beginning May 9, 2017, Microsoft released updates to Microsoft Edge and Internet Explorer 11 to block sites that are protected with a SHA-1 certificate from loading and to display an invalid certificate warning," the company announced.

The change, however, impacts only SHA-1 certificates that chain to a root in the Microsoft Trusted Root Program where the end-entity certificate or the issuing intermediate uses SHA-1. This means that enterprises or self-signed SHA-1 certificates won't be affected by this. They are, however, encouraged to migrate to SHA-2 based certificates as fast as possible.

"Microsoft recommends that all customers migrate to SHA-2, and the use of SHA-1 as a hashing algorithm for signing purposes is discouraged and is no longer a best practice. The root cause of the problem is a known weakness of the SHA-1 hashing algorithm that exposes it to collision attacks. Such attacks could allow an attacker to generate additional certificates that have the same digital signature as an original," the company notes.

    How would you feel if your open heart surgery that you need is cancelled because of a ransomware attack perpetrated with NSA tools?

    I'd feel pretty damned good about it. Maybe the bastards will secure their shit now. This is one of the best possible things anyone could have done to all affected; make them open their wallet.

    Yeah.
    Perhaps asking for the same volunteering spirit (and speed) as for SN editors will get them to install a Linux or a BSD on those machines, 'cause there's no money in UK's health budget to upgrade from WinXP.

      Is there money to pay the ransom?

        Funny enough.], it seems like paying the ransom once is cheaper in this case.
        That is... if you don't take into account the cost of the chaos; but who in her/his full mind would look into those costs? The path to freedom (or death) is capitalism, and everybody knows the capitalism is about privatizing the profit and socializing the cost/risk.
