SUMMARY: Yes, this is a scam.  Not maybe.  Not possibly. Wright is pretending he has Satoshi’s signature on Sartre’s writing.  That would mean he has the private key, and is likely to be Satoshi.  What he actually has is Satoshi’s signature on parts of the public Blockchain, which of course means he doesn’t need the private key and he […]

CVE-2015-7547 is not actually the first bug found in glibc’s DNS implementation.  A few people have privately asked me how this particular flaw compares to last year’s issue, dubbed “Ghost” by its finders at Qualys.  Well, here’s a list of what that flaw could not exploit: apache, cups, dovecot, gnupg, isc-dhcp, lighttpd, mariadb/mysql, nfs-utils, nginx, nodejs, openldap, openssh, […]

So I went ahead and did a podcast with Stewart Baker, former general counsel for the NSA and actually somebody I have a decent amount of respect for (Google set me up with him during the SOPA debate, he understood everything I had to say, and he really applied some critical pressure publicly and behind the […]
