Gli esperti di Sophos hanno comunicato che il codice sorgente del virus Cabir è stato pubblicato sul Web. Nei giorni scorsi, la società F-Secure aveva lanciato un allarme riguardante le nuove varianti di Cabir, Symb/Cabir-H e Symb/Cabir-I, in grado di replicarsi più velocemente dei predecessori. Secondo Sophos però il pericolo è minimo, poichè comunque l'utente deve accettare il file ricevuto via Bluetooth e poi installarlo manualmente.

I talk about a test where I had to penetrate a web application, and it wasn't "just one step" - the steps before compromise were mostly interesting too.

A proxy/Webcache is a computer which sits between your LAN and your Internet
connection, usually in the gateway. Its job is to capture and save every Web
page that the client machines in your LAN visit, so that the next time
someone requests a page, the proxy/Webcache already has it and sends it to
the client. This saves bandwidth and usually speeds Web navigation.

Title: Malware Roundup: The fast and furious of 2004
Source: SearchSecurity
Date Written: January 3, 2005
Date Collected: January 3, 2005
While antivirus researchers agree that Sasser, Netsky, and Bagle caused many
problems in 2004, they disagree on which of the malwares caused the most.
Ned Lindberg would give it to Sasser, arguing that test computers get hit
with Sasser packets three times a minute. He was unable to patch a Windows
2000 virtual machine because it got infected by Sasser before he could
download patches. Sasser also opened backdoors for other malwares to
exploit. Sophos' annual virus count found that Netsky variants accounted for
41.6% of virus activity by early December 2004, earning five of the slots on
Sophos' annual Top Ten list. McAfee AVERT (Anti-Virus Emergency Response
Team) rated 46 viruses as at least medium risk in 2004, compared to only
twenty in 2003. McAfee's list of top malwares included some lesser known
examples, mainly such spywares as Adware-180, Adware-Gator,
Exploit-ByteVerify, Exploit-MhtRedir, and JS/Noclose. While virus activity
dropped 5% annually from 2000 to 2003, it jumped in 2004, largely due to
feud between the authors of Bagle and Netsky. Researchers expect virus
activity to increase further in 2005 as cybercriminals leverage malware for
spam and phishing attacks.

Title: Anti-Santy worm on the prowl
Source: C-Net News
Date Written: December 31, 2004
Date Collected: January 3, 2005
F-Secure has found an "anti-Santy" worm in the wild that attempts to infect
sites targeted by the Santy worm and install a patch. The anti-Santy worm
searches Google for sites using the PHP Bulletin Board (phpBB) software
targeted by Santy and defaces their homepages to read "viewtopic.php secured
by Anti-Santy-Worm V4. Your site is a bit safer, but upgrade to >= 2.0.11."
Two different versions of the defacement lead to internet addresses in
Argentina, suggesting anti-Santy's origin. F-Secure research director Mikko
Hyppönen notes that though the worm attempts to help administrators fix
their systems, it increases traffic, slowing down site performance and
creating more problems for administrators. The Santy worm infected 40,000
sites by December 21, 2004, before Google blocked access to the query it
used. However, Santy also queried America Online and Yahoo search engines
for vulnerable sites.

Title: New, virulent Cabir mobile phone worms spotted
Source: InfoWorld
Date Written: December 28, 2004
Date Collected: January 3, 2005
F-Secure has announced the discovery of two new viruses based on the Cabir
code, Cabir.H and Cabir.I, that fix flaws that prevented early versions of
the virus from spreading quickly. The Cabir code demonstrated how to spread
a worm disguised as a security utility over mobile phones running the
Symbian operating system. Cabir sends a file, velasco.sis, over a Bluetooth
connection. Though the worm does not destroy any data, it can block
legitimate Bluetooth connections and consume battery power. The new worms
can spread more quickly--one change allows Cabir to search for new targets
if one target wanders out of range. Some clues, including increased Cabir
development and the fact that the new Cabirs seem to be made from recompiled
code, suggest that the Cabir source code has been published, though
researchers have found no copies on the Internet. To be infected, a mobile
phone must run a vulnerable version of Symbian Series 60 software with
Bluetooth in 'discoverable' mode.

hackers who have designed modifications for the people simulation to get
around obstacles presented in the game. While the hacks have been available
in web forums for download, some users say they are spreading to players who
have never installed a modification and would rather play the unhacked
version of the game. The problem results from file-sharing. Electronic Arts
allows players to save homes they have built within game to share with other
players. However, if a shared home includes a hacked game element, that
element overrides the original game version. Electronic Arts has since
reprogrammed its "Lot Exchange," where users can share game homes, to
identify houses containing hacked objects. However, Electronic Arts was slow
to respond to user complaints, prompting the game community to create its
own central list of identified hacks with their checksums and to program
scanners, similar to virus scanners, to weed out downloads with hacked
elements.

grsecurity 2.1.0 (Stable)
http://freshmeat.net/releases/183986/
grsecurity is a complete security system for Linux 2.4 that implements a
detection/prevention/containment strategy. It prevents most forms of address
space modification, confines programs via its Role-Based Access Control
system, hardens syscalls, provides full-featured auditing, and implements
many of the OpenBSD randomness features. It was written for performance,
ease-of-use, and security. The RBAC system has an intelligent learning mode
that can generate least privilege policies for the entire system with no
configuration. All of grsecurity supports a feature that logs the IP of the
attacker that causes an alert or audit.
