      Researchers have achieved the first practical SHA-1 collision, generating two PDF files with the same signature

        If you burn 110K in cash.
        And have a team of cyber security experts.

          When you're trying to steal millions, 100K is nothing.

          And of course, this cost will likely fall pretty quickly.

            How often does one SHA breach net you millions? Sometimes, certainly.

              Spearphishing.

                I don't follow. How does spearphishing combine with SHA in a general sense?

                  Today, yes. But in six months it'll be a script and $30K in compute power. In two years it'll be $500 of AWS time.
