Electric Grid Vulnerabilities Exposed August 2, 2010

Computer networks controlling the electric grid are plagued with security holes says a new Energy Department report based on the findings of 24 assessments of computer-control systems performed between 2003 and 2009. Many are VERY basic.

Proposed Clarification of National Security Letter Authority Raises Privacy Concerns (August 2, 2010)

The move to clarify the FBI's authority to demand electronic communications data is meeting with resistance. The change in language would allow the FBI to obtain information from Internet service providers (ISPs) with the use of national security letters, which do not require a warrant from a judge. Those targeted by the letters do not need to be suspected of wrongdoing; all that is required is that the material requested be considered relevant to counter intelligence or counter terrorism investigations. National security letters have been misused in recent years. Senate Judiciary Committee Chairman Patrick Leahy (D-Vermont) noted, "While the government should have the tools that it needs to keep us safe, American citizens should also have protections against improper intrusions into their private electronic communications and online transactions."

Texas Company Seeks Liability Settlement From Bank Over Fraudulent Transactions (August 2, 2010)

Dallas, Texas-based Hi-Line Supply, Inc. is attempting to get its bank to settle a liability claim over US $50,000 in fraudulent transfers. The bank claims that the entity requesting the transactions knew all the company's passwords. Hi-Line maintains that the bank should have been wary of the transactions because the payments were going to individuals who had never before done business with the company; the requests were made from IP addresses that were physically more than 1,500 miles from the bank and had not been used before to conduct any transactions; and the amount was out of the ordinary. The fraudulent transactions were made last August. Hi-Line has convinced a court to seek depositions from the bank to find out exactly what it knew about the transactions.

UAE to Ban BlackBerry Services as of October 11 (August 1, 2010)

Authorities in the United Arab Emirates (UAE) have decided to suspend Blackberry services until concerns about the security of the services are addressed. The Telecommunications Regulatory Authority will suspend services to Blackberry Messenger, Blackberry email and Blackberry web browsing as of October 11, 2010. The concerns lie in the fact that Blackberry data are exported off-shore and managed by a foreign corporation. The Emirates News Agency said, "Today's decision is based on the fact that. In their current form, certain BlackBerry services allow users to act without any legal accountability, causing judicial, social and national security concerns for the UAE." The issue of control is not unique to the UAE; other countries have expressed concerns about not being able to access communications conducted through BlackBerry devices.

(Schultz): Rumor has it that recent Blackberry models come with interceptor software. I wonder if UAE investigated this possibility before it suspended Blackberry services. ]

UK Government Plans to Stick With IE6 in Spite of Encouragement to Upgrade (July 30 & August 2, 2010)

Despite an online petition signed by more than 6,000 people urging them to upgrade away from Internet Explorer 6 (IE6), the UK government says it will keep using IE6, noting that "Regular software patching and updating will help defend against the latest threats." The government also cited the time and expense consumed by testing upgrades and said that it has not seen evidence that later versions of the browser provide improved security. Both French and German governments have changed their browsers from IE 6 precisely because they wanted to improve security.

-http://www.theregister.co.uk/2010/07/30/uk_government_sticks_with_ie_6/
[Editor's Note (Pescatore): Wow, what an incredibly bad decision. When there is a safety recall on UK government vehicles, do they just day "ah, too expensive - with a bit of duct tape and some finger crossing, the brakes probably won't fail"?
(Liston): The issue here has little to do with "browsers" and everything to do with a government which allowed itself to be locked into a narrowly defined platform by the vendors it chose to develop its (to use the British term) "bespoke" applications. The short-sightedness of accepting software that uses browser/platform-specific features as a means of accelerating/cheapening the development cycle has come home to roost. ]

Mumba Botnet Uses Zeus and Fast Flux (August 2, 2010)

The Mumba botnet comprises more than 55,000 compromised PCs and has been used to steal more than 60 GB of personal data. The botnet hides its activity with technology known as fast flux, which uses constantly-changing compromised hosts acting as proxies. Mumba began infecting computers in late April, when 35,000 machines became infected. Mumba uses several variants of Zeus malware to steal data. Half of the infected computers are located in the US and Germany.

Microsoft Issues Out-of-Cycle Patch for Remote Code Execution Flaw in Windows Shell (July 30 & August 2, 2010)

Microsoft has released an out-of-cycle fix for the critical shortcut vulnerability in Windows that is being actively exploited. The flaw has been exploited to install malware on supervisory control and data acquisition (SCADA) systems, software that manages elements of critical infrastructure. Microsoft has recently noted an increase in attempts to exploit the flaw. The vulnerability affects all supported versions of Windows. Internet Storm Center:

[Editor's Note (Ullrich): This is a "must apply" patch. Note that the initial announcement did not mention Windows XP SP2. As of last month, Windows XP SP2 is no longer supported and an upgrade to SP3 is adviced. However, in this case, unlike stated in Microsoft's advisory, Windows XP SP2 is still supported (silently?). ]

Terry Childs Denied New Trial; Sentencing Rescheduled (July 30, 2010)

Superior Court Judge Teri L. Jackson has denied Terry Childs's motion for a new trial and a request for arrested judgment. Childs is the former San Francisco city network administrator who refused to reveal passwords for one of the networks to his managers in 2008. Childs was scheduled to be sentenced on Friday, July 30, but the two defense motions consumed so much time that sentencing was delayed until August 6. In April, Childs was found guilty of denying computer services. Childs claimed that his actions were founded on security concerns; he was worried that the passwords would be shared indiscriminately. He eventually surrendered them to San Francisco Mayor Gavin Newsom when the mayor visited him in jail.

Leak of Afghan War Documents Prompts US Military Information Security Review (July 30, 2010)

The US military will review information security practices in the wake of the leak of tens of thousands of classified documents about the war in Afghanistan through WikiLeaks. Defense Secretary Robert Gates says that procedures for restricting the access and transportation of data have already been put in place.

Former CIA and NSA Chief Speaks About Need for Cyber Warfare Doctrine (July 29, 2010)

Speaking at the Black Hat conference in Las Vegas, Nevada, former CIA and National Security Agency (NSA) director Michael Hayden said that the US needs to establish rules for cyber warfare before the country becomes engaged in such a conflict. The arrangement might include an agreement not to target systems that support banks and electrical grids. The rules for cyber warfare engagement are not clear. Hayden acknowledged that attribution of attacks is difficult; one way to circumvent the issue would be to hold countries accountable for attacks emanating from their cyber space.

[Editor's Note (Ranum): That last line - attribution based on address domain - beggars the imagination. I hope more technology-literate minds get involved, quickly.
(Liston): Over the past 4 years I've run various incarnations of honeypot systems and I've rarely, if ever, seen an attack that I could conclusively attribute to a specific actor. Do we really want to go down a path where a country may be held responsible for an attack because it was "sourced" from Aunt Trudy's unpatched install of WinXP? What level of control would be required at the national level to make a system founded on that notion acceptable? ]
