Volume XII - Issue #68
August 27, 2010
Policemen are often forced to search for evidence of a crime after the criminal has systematically tried to erase it from their computer. A note we received last Sunday provides a short lesson on a not-widely-understood way that can be done. The note is included at the end of this issue for everyone who works in forensics, or hopes to do so.

TOP OF THE NEWS
Pentagon Opens Up About 2008 Cyber Attack (August 25, 2010)The Pentagon has acknowledged that a cyber attack in 2008 allowed an unnamed foreign intelligence agency to gain access to US military computer systems. The attack has been traced to an infected USB drive that was plugged into a computer at a US military base in the Middle East. "That code spread undetected on both classified and unclassified systems, establishing what amounted to a digital beachhead, from which data could be transferred to servers under foreign control," according to an article in Foreign Affairs by Deputy Defense Secretary William J, Lynn III.
Access to the full article by Secretary Lynn requires free registration on the site:
[Editor's Note (Schultz): The way these attacks spread once again give credence to the SANS term "pivot point." Additionally, it is troubling that so many attacks have crossed the border between unclassified and classified systems. ]
Cyber Security Likely to be Attached to Defense Authorization Bill (August 25, 2010)Noting that "it's hard to get a measure like cyber security passed on its own," US Senator Tom Carper (D-Delaware) said that legislators may attach cyber security legislation to a defense authorization bill, which is likely to pass before November's mid-term elections. Pairing cyber security with defense makes sense, said Carper, because cyber security is part of national security. Senate Majority leader Harry Reid has asked the chairmen of the various panels that have drafted cyber security legislation to meld their proposals into a single bill.
[Editor's Note (Northcutt): My best reading of the tea leaves suggests this is a variant of the Lieberman, Collins, Carper announcement in June. Here is a link to the stated provisions at that time and also a list of supporters of the current initiative. I guess this will be interesting for our industry:
Zurich Insurance Fined Over Data Loss (August 24, 2010)The UK's Financial Services Authority has fined the UK branch of Zurich Insurance GBP 2.27 million (US $3.53 million) for losing data of 46,000 customers. The data were on an unencrypted backup tape that was lost en route to a data storage center in August 2008; the company did not become aware of the missing tape for a year. The information includes names and bank account, credit card and other financial data. The fine was less than it could have been; had the company not agreed early on to settle, it would have been fined GBP 3.25 million (US $5.05 million).
Attorney Files Lawsuits Over Flash Cookies (August 24, 20100Privacy attorney Joseph Malley has filed a lawsuit against Specificmedia for using technology to respawn cookies that users have deleted. Malley has filed two other similar lawsuits: one against a number of companies, including MTV and Hulu, for using Quantcast technology to recreate cookies and another against Disney and Demand media for using a Clearspring Technology widget that does the same thing. All the technologies use Adobe Flash to store copies of browser cookies; while clearing regular cookies is fairly straightforward, clearing Flash cookies can be complicated because they cannot be managed through browser privacy controls. According to the lawsuits, the companies did not inform users about the use of Flash to store the information; the suits allege that using Flash in this way violates state and federal privacy and computer security laws. Flash cookies allow websites to store 25 times more information than traditional cookies hold.

THE REST OF THE WEEK'S NEWS
China Orders Companies to Use Domestic Cyber Security Products (August 25, 2010)The Chinese government has told banks and other large companies to limit their use of computer security technology from outside the country. The order is part of China's Multi-Level Protection Scheme, an effort to bolster new Chinese companies by eliminating foreign competition. The European Union wants the Chinese government to limit the restrictions to organizations involved in national security.
Apple Issues OS X Security Update (August 25, 2010)Apple has issued a security update for OS X to address 13 security flaws. Eight of the flaws have been rated critical. The flaws could be exploited to execute arbitrary code, access sensitive data, create denial-of-service conditions or impersonate hosts within a domain. The update affects Mac OS X 10.5.8 client and server and Mac OS X 10.6.4 client and server.
California Legislators Send Improved Breach Notification Bill to Governor Again (August 25, 2010)California legislators have passed a bill that would specify what information companies must include in data breach notification letters. The measure now goes before Governor Schwarzenegger, who vetoed a similar measure last year. If passed, the legislation would require breach notification letters to include the type of information compromised, the date of the incident, a description of the incident and phone numbers of credit reporting agencies. In addition, the companies would have to explain what steps they are now taking to protect affected customers and provide suggestions about what customers can do to protect themselves. If the breach affects 500 or more people, the companies would be required to send an electronic copy of the notification letter to the state's Attorney General. The measure would put California breach notification laws in line with the Health Information Technology for Economic and Clinical Health (HITECH) Act's notification requirements.
[Editor's Note (Schultz): Given his actions (or lack thereof) in the past concerning legislation related to protection of consumers, I predict that the California governor will quickly veto this bill. ]
Ireland's Central Applications Office Site Attacked Twice in One Week (August 26, 2010)For the second time in a week, the website of Ireland's Central Applications Office (CAO) was the target of a cyber attack.
[Ed: The CAO oversees the majority of college applications in Ireland. ]
The attack caused passwords to be reissued to 22,000 applicants. The CAO shut down portions of the site "while
IT team assessed the site." Several days earlier, the site was the target of a denial-of-service attack which rendered results of course offers unavailable to applicants. The CAO will conduct an internal inquiry into the attacks.
YoyoDdos Botnet Targets Chinese, US Sites (August 24 & 26, 2010)A botnet family dubbed YoyoDdos is believed to be responsible for nearly 200 attacks on websites in China, the US, Germany and South Korea. There are at least 70 variants within the YoyoDdos bot family and 34 command and control servers have been identified, the majority of which are in China. The attacks have targeted a variety of sites, including online merchants, blogs and hosting providers. Some attacks have lasted just a few hours, while others have gone on for two days.
Microsoft Releases Tool to Block DLL Flaw Exploits (August 23, 24 & 26, 2010)Microsoft has issued an advisory about the insecure DLL loading vulnerability. The issue affects certain applications running on the Windows platform. Exploits for the vulnerability have been released in the wild. Microsoft is checking to see if any of its own applications are vulnerable to exploit and has released a tool to block known exploits of the DLL preloading vulnerability. The flaw does not lie in Windows, but instead in the applications. Microsoft cannot address the problem in Windows without "breaking expected functionality."
[Editor's Comment (Northcutt): I think Microsoft is starting to turn the corner: ASLR, DEP and mitigation tools like this added to their patching methodology will, I expect, start to make it harder to attack their OS over the next year or so. For the last couple years the defensive community has been on the run, but I would love to see us gain at least a bit of the ground back.]
READER'S NOTE:The following note
[included here with permission ]
came to Rob Lee who is one of the nation's top forensics people and who directs the six-course SANS Forensics Curriculum and manages the principal forensics portal.
Hey Rob: I had to stall the SANS 508 course I was taking (via on-demand) due to a high profile case I was working on. The case involved online file sharing where the target was visited by police for items found in his publicly shared folder. When the search warrant took place, police members found out that the suspect had been discovered by his wife and had removed all the child pornography (C.P.) videos, including the ones that were documented in the investigation. When I got the computer and imaged the drive, nothing was there except deleted partial videos. Keyword searches discovered that at one time, he had hundreds of videos on the computer in his online file shares and incomplete folders. No external devices were located and found in the registry. We located a number of video artifacts in unallocated space and one in the recycle bin (I guess he forgot about that one). Keyword hits also pointed me to the System Volume Information. Not having done I returned to the course and got to the fourth segment that included the Restore Point and Shadow Forensics section, and this set me in the right direction. After seeing how I could follow the processes and leads from the course, I went into work on Sunday (annual leave) as I wanted to try this right away and see what I could find. Two hours into the process using the leads you document in this course and using Shadow Explorer, I hit on 7 videos of confirmed C.P. that I can now use to charge the suspect with possession and accessing C.P. I am guess that the rest are overwritten by the limitation of the Restore Points (15% of the hard drive in Vista) in the OS, unless you have any other ideas how I can recover move videos. In either case, I have enough to charge the suspect. The perma grin has not left my face since then (OK, it has only been a few hours) and when I informed the investigators, they were equally excited. Thanks for the SANS Forensics training and especially this course (my third so far), it has been a godsend. The course manuals will always be a great reference for me.
