Mein Freund Hendrik Müller ist mal wieder unterwegs.

Diesmal geht's mit dem Liegerad in den wilden Osten - er wird dabei einige Kilometer machen (2000KM sind angepeilt) und eine Menge Luft verbrauchen.
Thematisch passend sammelt er dabei Geld, damit eine WG von langzeitbeatmeten Leuten auch mal ein paar Kilometer machen kann und ihnen dabei die Luft nicht ausgeht, sie also mal einen Urlaub machen können. Urlaub braucht jeder mal und für die WG ist das halt etwas aufwändiger, die Reisetasche etwas größer und das Übergepäck nicht ganz billig.

Der Reisebericht von der Tour durch Schottland aus dem letzten Jahr incl. Katastrophenbericht ist auch lesenswert. Wenn ich auch finde, dass er nicht nur tolle Photos macht, sondern auch Katastrophen sehr schön beschreiben kann, hoffe ich aber, dass es in diesem Jahr einigermaßen glattgeht.

Ich lege mich jetzt mal auf 5ct pro Kilometer fest :-)

I would definitely watch "Adafruit - the musical (BYO soldering iron)"


Get a musical tour of Becky's favorite tools around the Adafruit factory please share

Lyrics:
Rulers and pliers and orange highlighters
Really sharp knives made by Olfa and Fiskars
Conductive fibers all wound up on spools
These are a few of my favorite tools

Circuit board stencil wipes, solderless breadboards
AC adapters with long USB cords
Autorange meters that count up the Joules
These are a few of my favorite tools

Trimming my nails with my flush Hakko snippers
Bright stranded wire and switches on zippers
Dangerous torches with pages of rules
These are a few of my favorite tools

When there’s blue smoke
When the thread jams
When the power’s out
I simply remember my favorite tools
Cause that’s what this song’s about

Wer am Samstag in Oldenburg ist, sollte unbedingt bei Katja auf ein paar Kilokalorien vorbeischauen.

This is completely fictional, of course, or is it?

So many interesting talks on the schedule for this year’s FOSDEM and so little time. At least I managed to upload a new (post-Snowden) GPG-Key on time to have it signed.
Will anybody Else from within my filter-bubble be attending?

#badBios > #independenceDay

Die #badBios Malware schleust angeblich per Soundkarte Daten vom Rechner. Mal abgesehen davon, dass sie sich angeblich auch noch über die Firmware von USB-Devices verbreitet und Cross-Platform ist - das wird langsam zu SciFi für mich.

Diese #BadBios Geschichte ist wirklich sehr merkwürdig.
Ausgefeilte Malware, die mindestens im BIOS wohnt und sich u.a. über die Controller in Medien wie USB-Sticks und Harddisks zu verbreiten scheint.
More on my ongoing chase of #badBIOS malware. It's been difficult to confirm this as I'm down to a precious few reference systems that are clean. I lost another one yesterday confirming that's simply plugging in a USB device from an infected system into a clean one is sufficient to infect. This was on a BSD system, so this is definitely not a Windows issue.- and it's a low level issue, I didn't even mount the volume and it was infected. Could this be an overflow in the way bios ids the drive?

Infected systems seem to reprogram the flash controllers on USB sticks (and cd drives, more on that later) to attack the system (bios?). There are only like ten different kinds of flash controllers used in all the different brands of memory sticks and all of them are reprogrammable, so writing a generic attack is totally feasible. Coincidentally the only sites I've found with flash controller reset software, are .ru sites, and seem to 404 on infected systems.

The tell is still that #badBIOS systems refuse to boot CDs (this is across all oses, including my Macs) there are other more esoteric problems with partition tables and devices on infected systems. Also USB cd drives are affected, I've bricked a few plugging and unplugging them too fast (presumably as they were being reflashed) on infected systems. Unsafely ejecting USB memory sticks has also bricked them a few times on #badBIOS systems for clean systems, though mysteriously they are "fixed" and reset by just simply replugging them into an infected system. Extracting data from infected systems is VERY tricky. Yesterday I watched as the malware modified some files on a cd I was burning to extract data from an infected system, don't know what it was yet, I have to set up a system to analyze that stuff.

On windows my current suspicion is that they use font files to get up to some nastiness, I found 246 extra ttf and 150 fon files on a cleanly installed windows 8 system, and three stand out, meiryo, meiryob, and malgunnb, that are 8mb, instead of the 7 and 4mb sizes one would expect. Unfortunately ttf files are executable and windows "previews" them... These same files are locked by trusted installer and inaccessible to users and administrators on infected systems, and here comes the wierd part, they mysteriously disappeared from the cd I tried to burn on a completely new system (a laptop that hadn't been used in a few years) that my friend brought over which had just been freshly installed with win 8.1 from msdn, with the install media checksum verified on another system.

I'm still analyzing, but I'm certain we'll ALL have a large problem here. I have more data and info I can share with folks that are interested.
