Coordinated Action Plan Addresses Bulk Power System Security Risks (October 20, 2010)

A November 2009 Workshop with the North American Electric Reliability Corporation (NERC) and the US Department of Energy resulted in the publication of a summary report, "High-Impact, Low-Frequency Event Risk to the North American Bulk Power System." NERC's Electricity Sub-Sector Coordinating Council then developed a Critical Infrastructure Strategic Roadmap and NERC worked with the electric utility industry to create a Coordinated Action Plan to address the identified risks. The plan identifies four specific scenarios, describes strategic initiatives to address the scenarios and lays out a plan with specific milestones.

[Editor's Comment (Northcutt): The second link is the plan itself and may be valuable to you in assessing your organization's COOP/DR/BCP plans in two regards. First have you considered these threats directly against your organization. Second, if one of these threats does have a high impact on the power grid, how long can you operate on generators and batteries?]

Facebook to Employ Encryption to Protect User IDs (October 25, 2010)

Facebook says it will use encryption and other data protection measures following reports that users' data were being shared with third parties. Facebook policy forbids application developers from sharing Facebook User IDs (UIDs) with third parties, but the company said that "some developers were inadvertently sharing
[the data ]
via the HTTP Referrer header." In related news, a Minnesota woman has filed a class-action lawsuit against Zynga, the company responsible for the popular FarmVille and Mafia Wars games on Facebook, for sharing user information with third parties, and data aggregator Rapleaf said it is no longer sharing user identifiers with advertising networks.


[Editor's Note (Pescatore): For all sites that are advertising-revenue driven, the real customer is the advertiser, not the user of the site. With that DNA, all security decisions are driven to assure that the integrity, and availability of the advertising is maintained. Confidentiality of the user's data, not so much. ]

Iranian Cyber Army May be Offering Botnet for Rent (October 25, 2010)

New research indicates that a group of hackers called the Iranian Cyber Army may be running a botnet in addition to their other malicious Internet activity. The group recently launched attacks against Twitter and Baidu in which they altered DNS records and redirected users to other websites. Research company Seculert found a page where the Iranian Cyber Army appeared to be offering the use of a botnet for a fee. The group is believed to be behind the botnet for hire scheme because the email address on the administration panel matches the address displayed after the attacks against Baidu and Twitter.

Firefox Extension Makes it Easy to Steal Cookies (October 25, 2010)

At the ToorCon 12 conference in San Diego, researchers presented a proof-of-concept Firefox extension that is capable of stealing session cookies from Facebook, Twitter and other accounts on unencrypted Web 2.0 sites on open wireless networks. The Firesheep extension was created to raise awareness about the problem of account hijacking from public Wi-Fi connections. User logins are generally encrypted, but most sites do not encrypt regular traffic, leaving cookies vulnerable to being grabbed.



[Editor's Note (Pescatore): If you want to push for SSL, WiFi hotspots forcing full-time SSL would stop this attack and be much less costly overall than all web servers using SSL on all sessions. ]

US Air Force Publishes Cyber Warfare Manual (October 25, 2010)

The US Air Force has published "Cyberspace Operations: Air Force Doctrine Document 3-12," the service's "foundational doctrine publication for Air Force operations in, through, and from the cyberspace domain
[and is meant ]
to provide insight for Airmen to follow." The manual focuses largely on defensive strategies and comprises lists of definitions, acronyms and reporting hierarchies.

UK ICO to Look Into Google Street View Issue Again (October 24 & 25, 2010)

The UK information Commissioner's Office (ICO) has reopened its investigation into the Google Street View data collection scandal. When the story first broke earlier this year, Google said the data inadvertently collected from unprotected wireless networks contained fragments of communications with no personal details. The company has since admitted that the collected data in some cases include entire email messages, URLs and passwords. In July, following a visit to Google offices to examine captured data, the ICO issued a statement that it was "satisfied so far that it is unlikely that Google will have captured significant amounts of personal data." In light of Google's recent admission, the ICO now says it "will be making enquiries ... before deciding on the necessary course of action, including a consideration of the need to use our enforcement powers."

[Editor's Note (Honan): This is a very unfortunate statement from the ICO as it undermines the confidence companies and individuals have in the effectiveness of any investigations conducted by the ICO. This coupled with the reluctance to impose serious fines on those found in breach of the Data Protection Act only reinforces that opinion. ]

Guilty Plea in Malware Installation Scheme (October 25, 2010)

A Scottish man who admitted to sending spam with malicious attachments has pleaded guilty to violating the Computer Misuse Act. Matthew Anderson had a major role in a scheme that used the malware successfully installed on users' computers to steal data and spy on the users through their webcams. Among the information found in Anderson's possession following a June 2006 raid on his home were wills, medical reports and photographs.


Media Content Groups Urge Quick Passage of Anti-Piracy Legislation (October 22, 2010)

Proposed legislation in the US Senate would make it easier to go after websites believed to be promoting piracy. The bill has the support of the Recording Industry Association of America (RIAA), the Motion Picture Association of America (MPAA) and other prominent media content organizations. The groups signed a letter to Senator Patrick Leahy (D-Vermont), who is one of the bill's sponsors. The Combating Online Infringement and Counterfeits Act does not allow the government to shut down the websites, but allows the US Justice Department to seize the sites' domain names and impose restrictions on credit cards and banks that would prohibit them from conducting further business with the alleged pirates.

Indian Authorities Seeking More Control Over Internet (October 22, 2010)

Authorities in India are meeting to develop plans to allow them the power to cut off Internet services in the event of emergencies. Officials from law enforcement and national security agencies say the goal is to protect Indian infrastructure from cyber attacks, but there are concerns that the new policies could allow the government more overall control over the Internet. The group wants to gain control of national gateways, which are now controlled by telecommunications and Internet companies. RSA's Vikas Desai compared shutting down the Internet in the event of attacks to closing a shop if vandals start throwing stones at it. He suggested "solutions like a massive firewall
[and ]
log management."

A Pair of Vulnerabilities in Linux (October 21, 2010)

A security flaw in the Linux implementation of the reliable datagram sockets (RDS) protocol could be exploited to obtain superuser rights on vulnerable systems. The vulnerability affects Linux kernel versions 2.6.30 through 2.6.36-rc8. Linux installations are vulnerable to the flaw only if the CONFIG_RDS kernel configuration is set and there are no restrictions on unprivileged users loading packet family modules. A patch for the flaw has been committed to the Linux kernel; distributions should be updated soon. A second, less serious vulnerability resides in the library loader of the GNU C library; this flaw could be exploited to gain root privileges on vulnerable systems.
