INSIDE DOPE ON SWEDISH HACK CONTEST
From: firstname.lastname@example.org (Bronc Buster!!!)
Subject: Please Hack this System?
OK, I know everyone out there has heard about this server
in Sweden that is
begging to get hacked (http://hacke.infinit.se/indexeng.html
<-- The Engilsh
Site). I will tell you all now, don't waste your time. Although
made this server a Public Domain and given the proper legal disclaimers
the authorities on placed them on their sites, this site (I'm
99% sure) CAN
NOT be hacked into. "What?" you say. Bronc Buster saying
a site is
UNhackable? Well this site in running on a MAC. Here is the server
(Information Provided by THEM!)
Computer: Power Mac 8500/150 with 64 megs of RAM, 2 gig HD.
Network: Standard Ethernet on a 10 baseT LAN.
Server: WebSTAR 2.0 with minimun plug-ins.
Operating System: Mac OS 7.6 running Apple Script. The Open Transport
upgraded to 1.1.2
Domain: hacke.infinit.se, IP 22.214.171.124
For those of you not familiar with a Mac web server, let me
give you a quick
crash course. It's more like a Windows web server than a Unix
web server (to
put into Windows terms). The Mac server has NO telnet process/program
attach to, and FTPs are not possible. Because of this lack of
a "shell" to
get into, so you may change their web site and get all that money,
very little possibilities for getting attached to their server,
In addition to this, if you COULD somehow attach, you would need
running a Mac, with AppleTalk of course, and be using a Mac TCP/IP
The only "hole" found on this server was the cgi-bin
directory, which on a
Mac server is not a hole at all.
I'm not a Mac lover by any means, BUT their Web Servers are
the most secure
on the net today and I'd put one of them up against a Unix system

The following advisory documents a recent security compromise

events as the situation progresses, releasing information as
allowed and deem it prudent.
Anyone with an account on freefall.freebsd.org is strongly
*CHANGE THEIR PASSWORD*, both on freefall and on any other machines
where the same password is used. Based on the Trojan horses
you should assume that your password was grabbed and transmitted
hostile 3rd party if you logged in at any time on or after January
18th, 1997. It does not matter if you logged in with ssh
telnet, you should assume that your password has been collected.
Furthermore, if you used ssh, rlogin or telnet on freefall to
to other machines then you should assume that password information
given to these programs was also compromised.
The break-ins occurred on at least 2 cdrom.com machines, root
compromised in both instances, and numerous system binaries had
horses inserted for the purpose of gathering and sending back
information. The method of entry used by the attacker(s)
is not so
important given that both systems were vulnerable to several
significant, now known, security exploits at the time and any
them could have been used to gain entry & root privilege.
more interesting about this attack is the sophistication of the
horses left behind, assembled as they were from a rather sophisticated
"kit" put together by someone who clearly knew their
way around a BSD
system. This told us that we should not take this attack

an immediate and obvious concern that the intruder may have taken
advantage of their temporary root privileges to make modifications
the FreeBSD master source repository, possibly to introduce back-doors
for later use or cause deliberate embarrassment by introducing
catastrophic failure modes.
Fortunately, neither scenario is as fearsome as it might seem.
one thing, the CVS repository is replicated on hundreds of machines
now, all syncing up with varying degrees of (deliberate) latency,
"CTM deltas" are also made continuously from this repository.
streams of CTM information can show exactly what changed from
to moment in the source tree, entirely independently of the CVS
mechanisms (which might be compromised) for doing so.
There is also the fact that there are many, many eyes on the
source tree right now, more than most of us probably ever thought
possible in the beginning, and it's hard to believe that someone
be able to slip a significant attack past the eyes of that many
people, watching their daily CTM deltas come by and reviewing,
do, each change with heavy skepticism before bringing it into
own source trees. To date, no reports of anything suspicious
We will continue to review our CTM deltas and we will look
of skullduggery, but we frankly feel that the real dangers here
not so much in recently introduced changes, which are easily
for and caught, but in those accidental security holes which
buried in the BSD code for months or possibly years. Since
seems to have become the theme of the month, and many people
volunteered (in light of our recent 2.1.6 security fracas) to
much more serious and comprehensive security audit, we will take
advantage of this opportunity to see that all code in the FreeBSD
source tree, old and new alike, is reviewed line by line for
overflows, unguarded copies, back doors, whatever. We may
not make it
through every last byte, but we can certainly focus on the "hot
(suid programs and system utilities) and do our best to prevent
problems like those which caused our recent headaches from reoccurring.
This advisory is simply to inform those people who have used
in the last 40 days or so that they should change their passwords
to explain to people that yes, there was a break-in to
freefall.freebsd.org and yes, we're aware of the issues this
both now and in the immediate future, and that we will be exerting
significant effort over the next few weeks in dealing aggressively
with security issues, both in FreeBSD and on the FreeBSD project
