“Finite Field Arithmetic.” Chapter 2: Logical and Bitwise Operations.

This article is part of a series of hands-on tutorials introducing FFA, or the Finite Field Arithmetic library. FFA differs from the typical “Open Sores” abomination, in that — rather than trusting the author blindly with their lives — prospective users are expected to read and fully understand every single line. In exactly the same [...]

“Finite Field Arithmetic.” Chapter 1: Genesis.

FFA, or the Finite Field Arithmetic library, differs from the typical Open Sores abomination, in that — rather than trusting the author blindly with their lives — prospective users are expected to read and fully understand every single line. In exactly the same manner that you would understand and pack your own parachute.

Still Tenser, Said the Censor.

Stay classy, YCombinator.

The Care and Feeding of the Sage SmartProbe.

Note: Please read the FAQ!!!
If you cured your Sage SmartProbe of its congenital disease as per the last article on the subject, you may now be wondering what to do with it.
The vendor supplied a massive Java shitware with the thing, which does not merit any discussion whatsoever. Instead, we will use the probe’s very [...]

How to Make Your Own Lamport Parachute from Common Household Materials.

The thought began, as many good things begin, in #trilema.
Users of the WOT, of V, and other systems where your cryptographic identity is wholly in your own hands1 live with a certain risk of “cryptographic death” – i.e. the compromise of one’s signing key. A conscientious user of public key crypto might keep the thought [...]

Phuctored SSH Public Keys.

Phuctored SSH Public Keys to date.
Keys were obtained from a scan of the complete IPv4 space. We have gone approximately 20% of the way through the data set at the time of this writing.
Click on the IP addresses to view a key in Phuctor, or on the SSH hello string to view pertinent discussions.

On the Matter of Brian Krebs.

The WWW of Brian Krebs, perhaps the second-most-worshiped1 patron saint to all English-speaking “computer security” charlatans — is sitting sadly offline today on account of a ~TB/sec DDOS flood.2
His titanic bandwidth, it turns out, was provided gratis by Akamai – spamatronicists par excellence and industrial-scale enablers of everything that makes the modern-day WWW a rancid [...]

Tears of the Phucked.

Phuctor – rewritten and revved up on new hardware in April – is presently eating SSH RSA keys from a scan of the complete IPv4 space.
And, on occasion, breaking some.
And generating other laughs as well.  In today’s server logs:
134.223.116.158 – - [22/Jul/2016:15:54:57 +0000] “GET /gpgkey/50840391E5677882196999C9AE77F3177E6CBF8D35FB4F1FEF848CFADF9088B1 HTTP/1.1″ 200 3425 “http://134.223.116.149:15871/cgi-bin/blockpage.cgi?ws-session=2010817170 ”
What’s that? A ‘Websense’ censortron control panel, [...]

The Phuctored and the Phucked

(8/16 Update: 113 moduli.)
Phuctor has been under lightweight but rather reliable DDOS in recent times, so here is a mirror of the list of 106 moduli broken up through the time of this writing.
Certain professional idiots have been bashing their heads against the wall in a futile effort to magic away the past.  To them, [...]
