Security researcher Dino Dai Zovi (of Pwn2Own fame) has released a suite of tools to demonstrate how to load an advanced rootkit on Mac OS X machines.

The tools were first discussed at this year’s Black Hat security conference where Dai Zovi (right) presented techniques to manipulate the way the Mach micro-kernel uses RPC calls to create hidden system calls or create kernel threads.

On the heels of a Black Hat conference demo of an iPhone hijack via text messages, Apple has shipped an iPhone update with patches for the security flaw.

The iPhone OS 3.0.1 update, available only via iTunes, addresses a memory corruption issue in the way the device decodes SMS (text) messages.   Apple warned that a maliciously crafted SMS message may lead to an unexpected service termination or arbitrary code execution.

Guest Editorial by  George Stathakopoulos

It seems like just yesterday when I was at Black Hat.  Now as I get ready to fly to Las Vegas again, I look forward to seeing a lot of security researchers, hearing their latest exploits and how they fared over the last 352 days.  At the same time, it is a great opportunity to look back at the past year in security and ask myself, “was it a good year or a bad year?”

What comes immediately to mind when I think of the past year?  The rise of rogue security software, Conficker, two out-of-band security updates (thanks to the MSRC for the great work!) and of course the fact that cyber security has garnered national attention fueling the search for a cyber czar.   Security researchers and analysts have said that security investments like the security development lifecycle (SDL) are making products harder to crack.   More people are interested in secure development, as seen by the uptick in downloads of Microsoft !exploitable and Threat Modeling tools.  More companies – Adobe comes to mind – are clearly demonstrating their commitment to protecting customers through security fundamentals.  And really, the collaborative spirit was obvious across the industry over the past year.   Read the rest of this entry »

The anti-sec group responsible for the compromise describes itself as a “movement dedicated to the eradication of full-disclosure“, has also threatened web sites and communities publishing exploits in a full-disclosure fashion.

BBC DDoS AttackThe British Broadcasting Corporation (bbc.co.uk) was hit by a DDoS attack on Thursday, according to a statement sent to the Inquirer :

“In a statement to the INQ, the BBC said the attack originated in a number of different countries but didn’t specify which. When the Beeb’s techies blocked international access to a limited subset of servers, it resulted in a marked improvement of the serving of bbc.co.uk. Service supplier Siemens was forced to block addresses and prevent the attack using other methods like changing the DNS settings.”

Cyber terrorists to face death penalty in Pakistan

Internet Users PakistanAccording to a recently signed “Prevention of Electronic Crimes Ordinance 2008” in Pakistan, any person who commits cyberterrorism causing the death of other people will face death penalty or life imprisonment :

“Whoever commits the offence of cyber terrorism and causes death of any person shall be punishable with death or imprisonment for life, and with fine and in any other case he shall be punishable with imprisonment of either description for a term which may extend to ten years, or with fine not less than ten million rupees, or with both.”

With cyber terrorism remaining an open topic term that could be greatly abused or wrongly interpreted, it’s interesting to see how a country with 3.5M Internet users reported in 2007 defines the term cyberterrorist, and is general cybecrime treated appropriately.

Memory exhaustion DoS vulnerability hits Google's Chrome

ChromeAditya K Sood from the EvilFingers community, which disclosed the first Chrome DoS vulnerability at the beginning of the month, has released a proof of concept demonstrating a memory exhaustion DoS vulnerability affecting Google’s Chrome versions Chrome/0.2.149.30 and Chrome/0.2.149.29 :

“The Google chrome browser is vulnerable to memory exhaustion based denial of service which can be triggered remotely.The vulnerability triggers when Carriage Return(\r\n\r\n) is passed as an argument to window.open() function. It makes the Google Chrome to generate number of windows at the same time thereby leading to memory exhaustion. The behavior can be easily checked by looking at the task manager as with no time the memory usage rises high. The problem lies in the handling of object and its value returned by the javascript function. Once it is triggered the pop ups are started generating. The Google Chrome browser generate object windows continuously there by affecting memory of the resultant system. Probably it can be crashed within no time. User interaction is required in this.”

What’s Google’s take on this flaw, and have they acknowledged it already? Zero Day asked the researchers.
