Wireshark released an update to fix multiple vulnerabilities in version 1.2.0. to 1.2.9. This release fixes several bugs. Wireshark indicated that It may be possible to make Wireshark crash, hang, or execute code by injecting a series of malformed packets onto the wire or by convincing someone to read a malformed packet trace file.

httpry is a tool specialized for the analysis of web traffic. The tool itself can be used to capture traffic (httpry -o file) but other other tools are better suited for that such as tcpdump, Snort, Sguil. When it comes to finding out if certain types of files were downloaded via http, this tool does a super job. It can be used in combination with regular expressions (Regex) to find if a file, a script or a malware was downloaded from site or by a host and will ignore everything else. Whether the http traffic is using port 80, 443, 8080, etc, it will parse and display all the web traffic using this simple command:
httpry -i eth0
If you are working with a large pcap file and want to filter on a particular IP or network, httpry support libpcap filters to zoom in on the web traffic you want to analyze. This libpcap filter will show all the web traffic associated with host 192.168.5.25 using this filter:
httpry -r file 'host 192.168.5.25'

If you are checking for a particular file extension such as.exe, .js, .msi, .jpg, etc, if you combined your search with grep, httpry can be used to find if any binaries (i.e. malware) were downloaded from a certain site or by a particular client using a pcap captured files. In this example we grep for all the JavaScript transffered by host 192.168.5.25.
httpry -r file 'host 192.168.5.25' | grep \.js

Fellow handler Kevin points us to new developments on this case, announced here ==www.fbi.gov/pressrel/pressrel10/mariposa072810.htm

New versions of Snort (Beta and Production)are both out. Release notes are here == http://www.snort.org/news/2010/07/28/snort-2-8-6-1-and-snort-2-9-beta-released/



New features that I'm finding interesting in 2.9 (Beta):

A Data Acquisition API (DAQ) is introduced in this version
A byte extract option that bears some investigation - this allows extracted values from one rule to be used in subsequent rule options
Some welcome updates for IPv6
Support for Intel's QuickAssist for use in pattern matching. This is by far the most interesting feature in the bunch (to me at least) - support for hardware based acceleration (on boxes that have this feature). QuickAssist uses FSB attached FPGAs for this, so builds on previous FPGA work. Attaching the FPGAs to the server FSB overcomes previous limitations in FPGA I/O rates (talk about the sledgehammer approach!), this likely raises the maximum throughput for Snort considerably!

More info on Quck Assist, and Snort's integration with it can be found here == http://www.intel.com/technology/platforms/quickassist/

and here ==http://download.intel.com/embedded/applications/networksecurity/324029.pdf

If anyone has used the new QuickAssist feature and has formal or informal benchmarks, please feel free to comment !

Paul wrote in to tell us about the new version of NoScript just out ==http://noscript.net/
The main new feature is protection against the Craig Heffner's DNSrebinding attack that's getting some press, which will be presented at Blackhat.this week ==http://www.blackhat.com/html/bh-us-10/bh-us-10-briefings.html#Heffner
The protection is pretty simple - look up the public ip of the workstation, and place it in the LOCALpseudo list. It uses a public site https://secure.informaction.com/ipecho for this - I can't comment at this time if this is a safe site to use for this or not.
If anyone has more info on this please feel free to comment.

This year's data breach report continues this valuable narrative. This years report is based on a larger case sample than in previous years, thanks to a partnership with the United States Secret Service, who contributed information on a few hundred of their cases this year. Many of the findings echo those of previous years (excerpts below).


Who is behind Data Breaches?

70% resulted from external agents

48% caused by insiders

11% implicated business partners

27% involved multiple parties



How do breaches occur?

48% involved privilege misuse

40% resulted from hacking

38% utilized malware

28% involved social tactics

15% comprised physical attacks



What commonalities exist? (this was the interesting section for me)

98% of all data breached came from servers

85% of attacks were not considered highly difficult

61% were discovered by a third party

86% of victims had evidence of the breach in their log files

96% of breaches were avoidable through simple or intermediate controls

79% of victims subject to PCI DSS had not achieved compliance



Come on! Not only don't folks seem to be implementing some basic protections, but when they're told that they've been compromised (in their log files), no-one is listening! I guess this isn't much different than in previous years, but it'd be nice to see a positive trend here.



I'm not sure that I believe the low numbers for government data breaches (4%). I guess the report can only summarize data from cases that are seen by the incident handlers.

Take a few minutes to read it over coffee this morning - Ifound it a good read, and just about the right length for that first cup !

According to this announcement:

http://secunia.com/advisories/40780/

The problem is that passwords may in certain cases be logged to /var/log/messages while running GNOME Display Manager in debug mode (disabled by default)



This was originally reported on 02-15-2009 here:

https://bugzilla.gnome.org/show_bug.cgi?id=571846

A patch was issued the same day. A supported patch was issued 05-14-2010.



The secunia advisory did not have many details.

The sunblog link provided did not have very much information.

http://blogs.sun.com/security/entry/cve_2010_2387_password_disclosure



The CVE is reserved and not available yet.

The rest of the information is apparently in the Customer Are.



Does this mean we can count on a no public disclosure policy for SUN products now that Oracle owns them?
