Windows 7 beta gets its first security update

Posted by Daniel Tumalad on March 12, 2009

This is Microsoft’s first release for Windows 7 [just being optimistic,  hopefully there won’t be alot more to come in the future]. This update is supposed to patch a critical Remote Code Execution bug along with two other spoofing related vulnerabilities.

Now available on Windows Update and Microsoft Download Center.

Curse of Silence Update

Posted by Jaime Raphael Licauco, CISSP, GSEC on January 9, 2009

F-Secure apparently has a solution for this, but you would have to pay for it after 15 days. I’ve also confirmed that this attack works on at least one of the major local networks. No word yet if they have changed their settings to what was suggested to stop the attack. Sony Ericsson UiQ devices were found by F-Secure to also be vulnerable to the attack.

Nokia isn’t very worried about it since it is a denial of service attack and doesn’t allow an attacker to leach information from your cellphone. I still think it would be very annoying if I would have to do a factory reset of my phone, losing all my contacts, settings and messages. I also wouldn’t like it if my competitor knows my company uses the vulnerable phones and starts shutting down SMS capabilities until we notice it. That could potentially hit productivity and the bottom line.

I have no details of the local test done except that it exists and it was possible. If one watches the video, the victim wouldn’t even know who sent the message. The phone just stops receiving messages… in other words, Nokia’s advice in the Heise Security article is pretty useless.

Nokia which got the demo around a month before the public release and which recently acquired Symbian, is currently working on a remedy for the vulnerability. I will post it here as soon as I get word of it.

Happy New Year to All :)

Posted by Jaime Raphael Licauco, CISSP, GSEC on January 6, 2009

A lot of people in the Philippines are probably still hungover from the long vacation from Dec 25 to Jan 4, unless of course they were part of sales, or a BPO… anyway, on to the news:

OpenVAS 2.0 was released around two weeks ago, and a respected security expert (who wishes to remain anonymous) thinks it is, “fast approaching the maturity level needed to truly compete with Nessus in the vulnerability assessment area.”

The OpenVas 2.0 press release states that:
OpenVAS is a fork of the Nessus security scanner which has continued development under a proprietary license since late 2005. Since the release of OpenVAS 1.0.0 in October 2007, the OpenVAS developers continued the auditing of the code inherited from Nessus and have added a variety of useful features for OpenVAS users, for server administrators and for developers of Network Vulnerability Tests (NVTs).


Some of the Philippines’ high ranking government officials may want to look into cellphone voice encryption (as mentioned in this SecurityPark.net article) before calling some other high ranking government official so that they wouldn’t need to give a televised public apology (wink).


Speaking of mobile phone security, there was a DOS vulnerability found in Nokia Series 60 cellphones just before new year’s eve called the “Curse of Silence”, which either stops the cellphone from receiving SMS until a factory reset is done (Series 60 2.6 and 3.0 devices) or not all SMS’s are received (Series 60 2.8 and 3.1).

This is done via the following steps (check out the demo video link below):
For Series 60 phones v2.2, 2.3, 3.0 and 3.1 attack target phones
1. create an email that has an e-mail address with more than 32 characters followed by a space.
2. set TP Protocol Identifier of SMS Message to Internet Electronic Mail
3. send message to target (eleven times to Series 60 v 3.1, only one message is needed for all other versions)

There are currently no client side workarounds published as of the moment. If ever you work for Smart Communications, Globe Telecom or Sun Cellular maybe your network team can take heed of the suggestion in the document that “network operators should filter messages with TP-PID ‘Internet Electronic Mail’ and an email address of more than 32 characters or reset the TP-PID of these messages to 0”. I also do not have a Series 60 phone mentioned in the list so I cannot test if it can affect cell phones here in the Philippines. Kindly drop me a line in case you were able to test this.

Info Sec News, Dec 4, 2008

Posted by Jaime Raphael Licauco, CISSP, GSEC on December 4, 2008

In a series of twists, Apple has pulled out its quietly released Anti-virus technote, stating that it was old. Noted exploit hunter Charlie Miller said that it was much to do about nothing (take note that this is the same guy that won the $10k who hacked the MacBook Air in under two minutes). On the same day that story went out, a new Apple malware was announced in SecurityPark.com. I’ll take the same line as Apple spokesman Bill Evans in saying, “Since no system can be 100% immune from every threat, running anti-virus software may offer additional protection”.

A rootkit was found in an Enterprise Information Security software, reports Heise Security and The Register.

Another vulnerability was found in the popular VLC media player. So if you can, update.

The Chicago Tribune reports that a new round of cyber attacks has the Pentagon worried. They normally get a whole number of attacks per day, however, the magnitude and way the new attacks are being done are apparently designed to specifically attack military networks. Heise also covers the same topic here and here.

The Linux on iPhone project has released the first results of its project.
