Let's play 33 bits on this guy, my guess is that he's German, Austrian or Swiss based on the settings for his IRC client, that should knock about 6 bits off, 27 to go.
> My bank had around 20,000 customers using smsTAN and 3 (I was the 4th lol) using HBCI.
He is German, of college age and an early customer at one of 2 or 3 banks that provide HBCI. Consider him nailed.
I also bet he has published security related work under his real name at some point, especially since he has been applying for jobs. Most people in the security industry applying for legit work who don't have qualifications pad out their resumes with online research (or speaking at conferences, etc.).
You have 17 bits left. Use them wisely.
He's probably lying too.
Interesting idiom. I hadn't heard it before, but the usage makes sense.
> Even if 90% of those 7,200 were mined by botnets, and 100% of those mined were sold, that would represent well under 10% of the daily trading volume.
This is a perfectly correct instance of the subjunctive mood (http://en.wikipedia.org/wiki/Subjunctive_mood), I think, not a language trap.
Edit: definitely not a Pole. Likely in former Eastern Germany though (lots of people there have a working knowledge of Russian / Polish, people from the Western parts not so much).
Universities in former Eastern Germany with an engineering department?
well, as a German, I'd like to point out that this might have something to do with the fact that he is kind of an asshole. There are nice and well-mannered people here too.
