TOP OF THE NEWS

EFF Says At least Four Certificate Authorities Have Been Breached Since June (October 27, 2011)

According to research from the Electronic Frontier Foundation (EFF), at least four certificate authorities have been compromised since June 2011. The information was gathered by examining publicly available documents that are required to be completed whenever secure sockets layer (SSL) certificate is revoked. There are more than 600 authorities. The breadth of the situation raises questions about the long term security of the technology. EFF Technology Projects Director Peter Eckersley wrote in a blog that, "as currently implemented, the Web's security protocols may be good enough to protect against attackers with limited time and motivation, but they are inadequate for a world in which geopolitical and business contests are increasingly being played out through attacks against the security of computer systems".
-http://www.theregister.co.uk/2011/10/27/ssl_certificate_authorities_hacked/
-https://www.eff.org/deeplinks/2011/10/how-secure-https-today
[Editor's Note (Liston): The entire SSL Certificate system is founded on the faulty premise that we should trust a corporation simply because they claim to be trustworthy. These companies have taken on a huge responsibility as a part of their business model, and have simply not taken the kinds of precautions one should take when voluntarily positioning oneself as the basket containing all the chickens.
(Murray): We do not have to have a perfect system of key management but vendors who want to offer services in the security space have to have good security. Their brands are essential to their viability and they are very fragile. ]

BT Must Start Blocking Newzbin 2 Within Two Weeks (October 26, 2011)

A UK High Court judge has given British Internet service provider (ISP) BT two weeks to implement a plan to block Newzbin2, a membership-only site known for making pirated content available. The ruling is the result of a lawsuit brought by US movie companies. The judge decided that BT was aware of the copyright infringement activity occurring on Newzbin2 and had ruled in July that the company must prevent its customers from being able to access that site. The judge also ruled that "the costs of implementing the order should be borne by BT."

wzbin2-40094286/

-http://www.bbc.co.uk/news/technology-15459005
[Editor's Note (Murray): Seems to me that BT is a victim here. They are being made responsible for the criminal activity of others. They are being forced to do something both expensive and ineffective. The Internet routes around censorship. How much damage are the rest of us supposed to endure because the publishers cannot figure out how to offer their products at a price both profitable to them and not so high as to create a black market?
(Liston): This all sounded somewhat reasonable up until the last sentence. If the movie companies expect ISPs to block access to sites at their behest, then they really should be footing the bill. They own the copyright, they benefit financially from its protection, so expecting a disinterested third-party to cover the costs of implementing a block on infringing websites seems a bit over the top. ]

Hacker Tool Launches DoS Attack Against SSL Server With One Laptop (October 25, 2011)

A group called The Hackers Choice has released a tool that can launch a denial-of-service attack against an HTTPS web server with just one laptop over a DSL connection. The tool exploits the SSL renegotiation feature to overwhelm the server. The Hackers Choice members recommend disabling SSL renegotiation. One of the members points to a series of issues with SSL that have become evident over the past few years, including a very high percentage of SSL-based sites that are not properly configured and the problems inherent in "giving hundreds of commercial companies (so-called Certificate Authorities) a master key to ALL SSL traffic."

Duqu May Not Be as Closely Linked to Stuxnet as First Thought (October 26 & 27, 2011)

Computers infected with Duqu malware have been detected in Iran and Sudan. Some researchers are saying that Duqu is related to Stuxnet, which was used to sabotage centrifuges at a nuclear facility in Iran. The Iranian systems infected with Duqu do not appear to be related to the country's nuclear program. Each instantiation of Duqu that has been found is unique, which makes it harder to detect. Others are now finding evidence that Duqu may not be so closely related. Researchers from Dell say that while Stuxnet and Duqu use similar injection techniques, there are also many differences between the two.

Attack Manipulates Insulin Pump Settings (October 27, 2011)

A researcher who last year developed a method of taking control of ATMs so they would dispense cash at his behest has now devised an attack that allows him to take control of certain wireless insulin pumps. The attack could be used to deliver incorrect doses of insulin to patients. The pumps in question, which are made by Medtronic, contain radio transmitters that allow doctors and patients to make adjustments. With specialized equipment, the attack could be conducted at a distance of up to 300 feet and does not require the attacker to know the device's serial number. The pumps at present do not use encryption while transmitting information.

Microsoft Settles With Czech Hosting Defendant (October 27, 2011)

Microsoft has agreed to ask the judge to dismiss a lawsuit against Czech Republic company it had accused of hosting command and control servers for the Kelihos botnet. An attorney with Microsoft's digital crimes unit said that "Microsoft has reached a settlement with defendants Dominique Alexander Piatti and his company, dotFREE Group SRO. ... We believe that neither he nor his business were involved in controlling the subdomains used
[by Kelihos, ... but that ]
the controllers of Kelihos leveraged the subdomain services offered by Mr. Piatti's cz.cc domain." The settlement includes a provision that Piatti delete or transfer all subdomains used in connection with Kelihos. Piatti will also work with Microsoft to develop methods for preventing the abuse of dotFREE subdomains in the future. Microsoft's case will proceed against 22 John Doe defendants.

US Government is Providing Banks With Cyber Threat Information (October 26, 2011)

The National Security Agency (NSA) is helping US banks in their efforts to protect their computer systems from intrusions and other attacks. The FBI has also been providing banks with warnings about specific threats. Officials are concerned about the increasing sophistication of attacks launched against financial institutions.

Hackers Interfered with US Satellites (October 27, 2011)

Attackers managed to interfere with two US government satellites four times in 2007 and 2008, according to a draft of the annual report of the US-China Economic and Security Review Commission. The targeted satellites are used in climate and terrain data gathering. The report did not offer specifics about the satellite intrusions, but did say that access was gained through the Svalbard Satellite Station in Spitsbergen, Norway. The report is scheduled for release in November 2011.

Nasdaq Breach May Have Been Worse Than Initially Thought (October 25, 2011)

The breach that compromised data on a Nasdaq server that was acknowledged earlier this year appears to be more serious that first thought. Two people with access to information about the investigation into the incident say that although trading servers were not directly attacked, the attackers did manage to infect sensitive systems with malware. Nasdaq OMX group acknowledged in February 2011 that its servers had come under attack, and that some servers associated with the Directors Desk collaboration and communications tool contained suspicious files. The attack was said to have occurred in October 2010 and that the files were removed immediately. Nasdaq was asked by federal law enforcement authorities to delay breach notification so as not to interfere with the investigation. The investigation is likely to find evidence that the attackers exploited flaws in web applications; that "virtual insider trading occurred;" and that the platform for the attack was Directors Desk.

Proposed Legislation Would Broaden US Government's Authority to Blacklist Piracy Websites (October 26, 2011)

Legislators in the US House of Representatives have introduced a bill that would increase the government's authority to shut down web sites that offer products that violate copyright and trademark laws. The proposed legislation would allow the Justice Department to obtain court orders requiring ISPs in the US to stop resolving DNS for the offending websites; the sites could still be accessible outside the US. The bill would also allow the government to order search engines to remove certain websites from their results. The US attorney general would also be granted the authority to block distribution of workarounds to allow access to blacklisted sites.

Data Security Rules May Prevent LAPD From Migrating to Cloud Services (October 26, 2011)

The Los Angeles Police Department's (LAPD) plan to migrate to Google Apps has been put on hold indefinitely because of FBI security rules. According to FBI Criminal Justice Information Services security policies, state and local law enforcement agencies have to maintain "management control" over criminal justice data security. All Los Angeles City employees are using Google Apps except for law enforcement.
-http://www.nextgov.com/nextgov/ng_20111026_6213.php?oref=topstory
[Editor's note (Liston): Sometimes, maintaining the confidentiality, integrity, and availability of sensitive/critical information is going to be in direct conflict with doing things easier and cheaper. What I find newsworthy in this piece isn't that the FBI rules block this migration, but that someone at the LAPD actually thought it was a good idea to begin with.
(Honan): This case highlights one of the compliance concerns relating to cloud computing and how important it is to clearly understand all your legal and regulatory obligations when engaging with a cloud provider. This challenge is exasperated by the ease people can sign up for cloud services simply by using a credit card. It would be prudent to engage with your accounts department to monitor company credit card statements for subscriptions to cloud services so you can ensure all such services are compliant.
