New Cyber Novel
"Fatal System Error" comes out Tuesday; it is hard to put down - like a good spy thriller should be. But this one is all true. A rare inside look at the Russian (cyber) mafia's methods. Joe Menn, the Financial Times journalist, wrote it.

TOP OF THE NEWS
Clinton Speech Addresses Internet Censorship/Google (January 21, 2010)US Secretary of State Hillary Clinton said in a speech on Thursday, January 21 that her department will introduce several initiatives aimed at fighting Internet censorship. It will also develop ways to help citizens of countries where content is blocked circumvent the barriers put in place so that they can have unfettered access to information. Clinton also reiterated the US's intent to file a formal protest over the alleged attacks that targeted email accounts of human rights activists and will look to the "Chinese government to conduct a thorough review" of the attacks against Google.
India Says Attack on Government Computers Came From China (January 19, 2010)India's security advisor said that Indian government computers were attacked on December 15, the same day that some US companies reported having been attacked. The attack on the Indian computers came through a maliciously crafted PDF file that arrived as an attachment to an email. A Chinese foreign ministry spokesperson called allegations that the attack originated in China "groundless."
Chinese Search Engine Baidu Sues Domain Registrar Following DNS Attack (January 19 & 20, 2010)Chinese search engine company Baidu has filed a lawsuit against a US domain registrar following a DNS attack that redirected computer users from Baidu's site to a page that claimed the attack was the work of the Iranian Cyber Army, the same group that launched an attack on Twitter late last year. The site itself was not harmed in the attack. The lawsuit alleges gross negligence and seeks damages. The domain registrar, Register.com, says the suit is entirely without merit.
Heartland Will Move to End-to-End Encryption (January 20, 2010)Heartland Payment Systems is moving to an end-to-end encryption system so merchants will not ever store cleartext card data on their computers. Last January, Heartland acknowledged that it suffered a massive data security breach, compromising a significant number of payment cards. The end-to-end encryption is right now an opt-in choice for merchants because it requires purchasing new hardware. However, if the merchant has the new technology correctly deployed and still suffers a breach, Heartland will assume liability.
[Editor's Note (Pescatore): Less sensitive data in the clear is a good thing, whether in motion or at rest. However, doing encryption (especially managing keys) effectively and efficiently isn't easy - encryption done badly can be the worst of both worlds.
(Paller): Sadly the encryption that Heartland is proposing would not have stopped the attacks that stole the data that damaged so many Americans.
(Ranum): People who think end-to-end encryption between insecure end-points is going to solve any meaningful security problem simply do not understand security. ]

THE REST OF THE WEEK'S NEWS
Lawyers Say Proposed Heartland Visa Breach Settlement is Too Low (January 21, 2010)Lawyers for the financial institutions in the Heartland Payment Systems-Visa settlement said that the proposed US $60 million is inadequate. Heartland offered the settlement to reimburse the card issuing institutions for costs incurred by the Heartland data breach disclosed a year ago. If the financial institutions had agreed to the settlement, Heartland and Visa would not be liable for any claims regarding the breach in the future.
Researchers Finds Evidence in Attack Code Used on Google That Points to China (January 19, 20 & 21, 2010)A security researcher says he has found evidence linking the recent attacks on Google to China. Analysis of the software used in the attacks revealed that it contains an algorithm from a Chinese technical paper that was published only on Chinese-language websites.
Microsoft Warns of Vulnerability in 32-Bit Versions of Windows (January 19, 20 & 21, 2010)Microsoft has issued a security advisory warning users of a vulnerability in 32-bit versions of Windows that could be exploited to install programs, alter data, and create new user accounts. The problem affects 32-bit versions of Windows 7, Vista, XP, 2000 and Windows Server 2003 and 2008. 64-bit versions of the operating system are not affected by the vulnerability. To exploit the flaw, attackers would need to log on to a system locally. Until a patch is available, users are advised to disable the Windows Virtual DOS Machine (NTVDM).
Adobe Issues Shockwave Update (January, 20, 2010)Adobe has released an update for Shockwave to fix a pair of vulnerabilities that could be exploited to inject and execute code. The flaws affect both Mac OS X and Windows versions of Shockwave, through versions 126.96.36.1992. Adobe's recommended update method for this particular patch involves uninstalling older versions of Shockwave, rebooting the computer and installing Shockwave version 188.8.131.526.
[Editor's Note (Schultz): What an awful patch installation procedure! Given its complexity, I seriously wonder how many organizations (let alone individuals) will be willing to invest the effort to make this patch. Surely Adobe could do better than this. ]
Apple's First Security Update of 2010 Fixes a Dozen Flaws (January, 20, 2010)Apple computer has released a security update to address a dozen flaws in Mac OS X 10.5 and 10.6. Security Update 2010-001 includes fixes for seven arbitrary code execution flaws in the Adobe Flash Player plug-in and a denial-of-service vulnerability in the CUPS printing service; it also disables Transport Layer Security renegotiation in OpenSSL to prevent man-in-the-middle attacks.
Microsoft Issues Out-of-Cycle Patch for Zero-Day IE Flaw Used in Google Attacks (January 21, 2010)Microsoft has released an emergency, out-of-cycle patch to fix the zero-day memory corruption vulnerability in Internet Explorer (IE) that was used in attacks against Google and other US companies in the last few weeks. At first, the vulnerability was limited to attacks on IE 6, but the code has been modified so that it presents a threat to newer versions of the browser as well; Symantec is reporting that malicious code attempting to exploit the vulnerability has been detected on hundreds of websites. Microsoft has acknowledged that it first learned of the vulnerability last August.
[Editor's Note (Northcutt): We depend on vendors like Microsoft to develop safe software and release a patch in a timely fashion when a critical vulnerability is discovered. To have known about this in August and not to have patched it is a breach of trust with their customers. That said, Microsoft and Adobe are clearly not going to change. How many years have we been reading about vulnerabilities in Internet Explorer? Prudent businesses need to start thinking about a backup plan, an alternative to today's massively complex Internet browser based services, for instance a browser that does not support any scripting. When Firefox was first released, it did not support Active X and yet it survived and prospered, I am able to do most things with NoScript, but NoScript is a plugin in another massively complex piece of software (Firefox) that also has had a large number of vulnerabilities. A display only browser might be an idea whose time has come. ]
Virgin to Test Deep Packet Inspection Technology to Look for Illegal Downloading (January 19 & 21, 2010)Virgin Media will test a system that uses deep packet inspection to find out if its broadband customers are downloading media files illegally. Once traffic has been identified as being of the file sharing variety, the content will be tested against a database of music and movies. The system currently does not note the associated IP address of the downloader, but Virgin would not rule out the possibility of identifying copyright violators in the future. The test will monitor traffic of about 40 percent of Virgin Media broadband customers; they will not be made aware that their activity is being monitored.
Bing to Cut Data Retention Time (January 19 & 20, 2010)Microsoft will reduce the amount of time it Bing search engine retains search data to six months. The change will occur over the next year-and-a-half. The policy until this point had been to remove data from the retained information that could be used to identify the individuals requesting the information, but other data, including the associated IP address, remained accessible for 18 months. Microsoft's decision to make the change came in response to an April 2008 recommendation from the European Union's Article 29 Data Protection Working Party.
