Quote from the PDF:
This virus appears to have been written by a beginner to
Motorola 68000 assembler programming, based on the use
of ‘lea/mov -(sp)’ instead of ‘pea’, a test for zero after an
‘and’, the apparent inability to decide between ‘clr’ and
‘sub’, and so on. Such things would be forgivable in a true
beginner, but the virus author is a well-known security
researcher. He released the virus source code under his own
name, Piotr Bania, rather than one of his aliases (‘Lord Yup’
and ‘dis69’). It’s funny, in a way, that the first virus that we
know he wrote came only after he left the 29A virus-writing
group. In any case, it’s still a virus, and that is to be
condemned. Just because you can write one doesn’t mean
that you should.
You can find Piotr Bania's virus writing nickname Lord Yup on the Virus Writers List (cached)

The end of last week there was large-scale police roundup of 29A members, 29A being the notorious international virus-writer group. The Czech police detained Benny and Ratter, two leading members. We also have unconfirmed information that Vallez (from Spain) and dis69 (Poland) have also been arrested.
Benny was picked up for the suspicion of writing or helping write Slammer. This Internet worm caused a major epidemic in January 2003. His computer was taken for in-depth analysis. Benny was released by police on Sunday. They asked him for Ratter's contact details. We don't have official information about any legal action yet.
The 29A site has a note that dis69 (Poland), also known as Yup, has left the group. At this point, we don't have any information regarding the capture of other 29A members: Vecna, Z0mbie, VirusBuster.
