I used the generic term DS8000, but I don't recall the exact device type. I
think that, as other mentioned, the point is that you do not need to access
the mainframe itself in order to damage the data.

I've a favorite author who points out that criminals mostly are optimists.
They think everyone else is a sucker and they're smarter than everyone else,
they therefore think they can't get caught, and they risk 12 years in prison
for a haul they could get with a mere eight months of honest work.
If we're still talking about the Logica hack, the reading I did on it says they
got their hands on an ID that had read access to the RACF database. So the
initial entry was the same as it almost always is; someone was careless with a
password. After that they did other things, mostly in OMVS
Is the **algorithm** documented... you know, in words, with examples?

Other things in the store don't make sense. It's either BS or the hacker
was given special access to the facility.

Well, I will be the one to call this story BS.

Agree. my point is that a mainframe is just another server and that
you don't need to login into to damage the data.

I have a lot of personal experience with the LZW patent, up to and including
paying royalties to Unisys.
I will not bore this group with my whole long story. Suffice it to say that
this was one of the first "stealth" patents. At the time I implemented and used
the algorithm there was no public
The long periods of bad guy access are typical. You read most of the breach
stories the attack unfolded over weeks or months. The hackers talk about pwning
