Lots of stuff has been written about
this blog post from RSA
describing the (potential) details of the attack, so I will refrain from
detailed comments on this piece that Marsh Ray nicely called “some of the most
egregious hyperbole I’ve read in infosec”.
Just one short note. Presumably the attack, in an early stage, used a
“spreadsheet [that] contained a zero-day exploit that installs a backdoor
through an Adobe Flash vulnerability (CVE-2011-0609)”.
TROOPERS11 was a blast! We received great feedback from all attendees and
speakers. This really pushes ourselves towards the next goals and an even better
security conference in 2012.
We’re happy that everybody got home safely with new ideas and inspirations in
mind. On a side note: The awesome TROOPERS badge caused trouble for some of
you with the airport security 😉 I really hope everybody could find a way to
take it back home. It will hopefully find its way to an adequate place right
next to your old memorabilia (cup of the first won soccer match, your college
degree or photos from your first ballet show). Regard it as the proof of your
latest achievement and tell everybody proud and loud: WE ARE TROOPERS.
Some of you may have heard of the
break-in at RSA and may now be wondering
“what does this mean to us?” and “what can be done?”. Not being an expert on RSA
SecurID at all – I’ve been involved in some projects, however not on the
technical implementation side but on the architecture or overall [risk]
management side – I’ll still try to contribute to the debate 😉
Feel free to correct me either by comment or by personal email in case the
following contains factual errors.
Reading
this advisory
I’m quite tempted to emit another rant on the relationship of heavy use of 3rd
party components, lack of (security) quality assurance and services running at
times where they’re not needed (see second workaround
here).
I’ll refrain from that for today. Just wanted to let you know that the
underlying vulnerability
in Struts2 was initially discovered by Meder Kydyraliev who gives
this talk
at Troopers in two weeks. He’ll certainly describe the
inner workings of this one, and others… 😉
Just a short addition to the previous posts
([1],
[2])
on IPv6 security today. In the last two days I had the opportunity to sharpen my
understanding of some aspects of IPv6 behavior in (Windows-) LANs. Actually I
gave an IPv6 workshop for some members of the “Project Services” team of
Hamburg-based computer & competence IT-solutions provider
[btw: thanks to Mr. Wendler of CuC for organizing it, and thanks to Mr. Cassel
for the breakfast…].
this post is the sequel of
this one
on the IPv6 security feature called “RA guard”. As announced in that post I
recently got a 4948 on ebay. After installing the appropriate image and noticing
that RA guard was still unavailable I found out it should have been a 4948E
which is capable of “doing IPv6 in hardware” (as opposed to the “simple 4948”
only supporting IPv6 in a “software switched” way. and pls note there’s also the
informal term 4948-E denoting a 4948 running an “enhanced image”).
gtp_scan is a small python script that scans for GTP (GPRS tunneling protocol)
speaking hosts. To discover those hosts it uses the GTP build in PING mechanism,
it sends a GTP packet of the type ECHO_REQUEST and listens for an incoming GTP
ECHO_REPLY. Its capable of generating ECHO_REQUESTS for GTP version 1 and GTP
version 2. Also the script can scan for both, GTP-C and GTP-U (the control
channel and the user data channel), only the port differs here.
just a short, somewhat non-technical, post today: I really like
this response Ross Anderson
gave to the “UK Cards Association” asking Cambridge University for taking
offline a thesis of one of their students. It (the letter) pretty much
summarizes how security research should be treated and backed by those
interested in a more secure world we live in.
On a personal note I’d like to add that Ross’ main volume “Security Engineering:
A Guide to Building Dependable Distributed Systems”, initially published in 2001
and updated in the interim with a second edition in 2008, has been the most
influential security book for me on my long way in the infosec space (which
started back in 1997, with some workshops on firewalls I gave for IT auditors).
If I could take only one infosec book to a lonely island, it would be this one.
at first a happy new year to our loyal readers (and, of course, to everybody
else too ;-)! We hope you all had some pleasant transition times, not suffering
from bad hangovers after 27C3 or sth 😉
Things are heating up for Troopers and in the course
of that we started putting together the slides for the workshops (I’m delighted
that Flo told me today there’s already quite a number of bookings for the
workshops…). I myself will give the “IPv6 Security in LANs” workshop, together
with Christopher. The workshop preparation will be accompanied by a series of
blogposts with three main areas to be covered:
The British Standards Institution recently published “Cloud Computing. A
Practical Introduction to the Legal Issues”. I ordered an electronic copy
yesterday (I did that
here, for
GBP 30) and after a first glance can say there’s lots of valuable information in
it.
Merry christmas to everybody, have some peaceful and relaxing days
