[and that Sony ]
cannot ensure or warrant the security of any information transmitted" to the company through PSN. Plaintiffs have until November 9, 2012, to amend and resubmit their complaints.
[Editor's Note (Pescatore): Since software still really can't be considered an engineering discipline, software does not come with a warrantee and systems built from software don't either. However, there are still due diligence standards for commercial enterprises when they take customer's money, there are "attractive nuisance" kinds of liability approaches, etc. I'm sure class action suit lawyers will continue to cause Sony to be paying millions to defense lawyers - further increasing the vast amount more this incident will cost them than it would have ever cost to be secure enough (even if not "perfect") in the first place. ]
FTC Settles With Web Analytics Company Over Improper Harvesting and Use of User Data (October 22 & 23, 2012)The US Federal Trade Commission (FTC) has reached a settlement with web analytics company Compete over allegations that it collected consumers' private information without permission. Compete gathers browsing behavior data and uses it to create reports which it then sells to clients. The complaint also alleged that the data, which included financial account information and Social Security numbers (SSNs), were not adequately protected. The FTC said that Compete's claims that it was interested only in which sites were visited and that personally identifiable information would be removed were "false and deceptive." Compete has agreed to obtain explicit consent from users before gathering browsing data. It will also delete or remove identifying information from the data it has already collected. The company will provide users with directions for removing its software from their computers.

THE REST OF THE WEEK'S NEWS
US Copyright Office Rules on DMCA Exemptions (October 25, 2012)Every three years, the US Copyright Office entertains requests for exceptions to the Digital Millennium Copyright Act (DMCA). Those that are granted are valid for three years. Earlier this week, the US Copyright Office rejected proposals that would have legalized people copying their DVDs for personal use and jailbreaking gaming consoles so that they can run software other than that provided by the manufacturer. The group did renew its approval for jailbreaking smartphones, but denied the same permission for tablet devices.
[Editor's Note (Pescatore): Good example of how laws that try to directly address technology almost invariably end up in hopeless messes. Soon there could be a DMCA ruling that it is OK to "jailbreak" the computer in my station wagon but not in my pickup truck. ]
CERT Urges Organizations to Replace eMail Signing Keys Smaller Than 1,024 Bits (October 24 & 25, 2012)Several prominent companies have fixed a cryptographic security issue in their email systems that allowed attackers to create spoofed messages. The issue lies in DomainKeys Identified Mail (DKIM) keys of less than 1,024 bits. DKIM provides digital signatures for email that verifies the domain name through which it is sent. Microsoft, Yahoo, and Google have all addressed the issue in their systems. US-CERT has issued a vulnerability note about the problem that recommends replacing all RSA signing keys with fewer than 1,024 bits.
US-CERT Vulnerability Note:
[Editor's Note (Murray): Crypto is the one security mechanism that is stronger than we need for it to be. Code signing keys may have a very long life, so strength is more important. E-mail has a short life and few rely heavily on the cryptographic signing. Moreover, such attacks as we see are against the systems protecting the keys, not the keys themselves. Short e-mail signing keys are a vulnerability without a threat. While the fix is cheap, there is no urgency.]
Huawei Provides Australian Government with Complete Access to Source Code and Hardware (October 24, 2012)Chinese technology company Huawei is giving the Australian government "complete and unrestricted access" to its source code and hardware in the hope of quelling concerns that its products contain backdoors and other hidden features. Australia excluded Huawei from bidding on providing equipment for the country's national broadband network. While Huawei has provided equipment for the UK's national broadband networks, the company is facing a more hostile environment in the US: a Congressional report urged US companies to refrain from using Huawei and ZTE products due to concerns that the companies may have close ties with the Chinese government.
Barnes & Noble Removes PIN Pads After Learning of Breach (October 24, 2012)Barnes & Noble has removed PIN pads from all of its US stores after learning that more than 60 of the devices in eight states showed evidence of tampering. Customers who have used debit cards on the PIN pads in the stores are urged to change their numbers. Customers who used credit cards should check their statements for unauthorized transactions. The breach was detected in September, and affected just one PIN pad in each of 63 stores. The attackers had placed code on the point-of-sale (POS) devices to harvest the data.
[Editor's Note (Murray): Proper operation of POS devices will not compensate for the fundamental vulnerability that mag-stripe and PIN is vulnerable to replay in the point-of-sale application.]
Facebook Donates Funds Seized From Spammers to Cybercrime Research Facility (October 24, 2012)Facebook has donated US $250,000 seized from spammers to an academic organization focused on fighting cybercrime. The University of Alabama at Birmingham's Center for Information Assurance and Joint Forensics Research will use the funds to expand its facility. The Center has helped researchers with the Koobface and DNSChanger attacks.
Adobe Updates Shockwave (October 23 & 24, 2012)Adobe has released an updated version of Shockwave to address half a dozen critical security issues. Five of the flaws are buffer overflows; the sixth is an out-of-bounds array vulnerability. Updates are available for Windows and Mac operating systems; users are urged to update to version 184.108.40.2068. Journalist Brian Krebs recommends that users check to see if Shockwave is even installed on their computers; if it is not, the update page will prompt users to download Shockwave, but if users have been living without it, they probably don't need it. Krebs also recommends that if users do choose to download Shockwave, they should look carefully for pre-checked extras.
Privacy Rights Groups Wary of Copyright Alert System (October 23 & 24, 2012)Privacy rights groups plan to keep a close eye on a new system that will have US Internet service providers (ISPs) warning customers whose activity is believed to be violating copyright law. The Copyright Alert System (CAS) does not provide for cutting off users' Internet access as a consequence of illegal filesharing, but throttling Internet speeds is a possibility. Time Warner Cable, one of the participating ISPs, said that it might temporarily suspend customers' accounts as part of its implementation of CAS. Content owners will be responsible for monitoring filesharing networks to identify alleged illegal filesharers. If CAS is true to its stated purpose of educating users, then it could be a good thing, but there are concerns that it could turn into a system to punish users.
[Editor's Note (Murray): A business model that transfers the cost of its security to its customers and third parties, is fundamentally broken.]
Megaupload Customer Seeking to Have Documents Related to January Raid Unsealed (October 23, 2012)Kyle Goodwin, an Ohio man who has been unable to access his legitimate files on Megaupload's seized servers, is asking a federal judge in Virginia to unseal documents, including search warrants, related to the January 2012 raid that resulted in the servers' seizure. The Electronic Frontier Foundation (EFF), which is representing Goodwin, says Goodwin needs the records to establish his case for the return of the content stored on the servers.
[Editor's Note (Honan): Mr Goodwin's unfortunate experience should serve as a lesson to any business moving their data or systems into the cloud. When migrating to the cloud make sure you update your business continuity plan to take into account the scenario where you cloud provider is no longer available due to system failure, going out of business or suffering a disaster themselves. ]
CONTROL SYSTEMS SECURITY STORIES
CONTROL SYSTEMS SECURITY STORIESOffense has the advantage - if you make it your political priority. Langner persuasively points out that U.S. cyber capabilities are heavily weighted towards offense, and not so subtly fingers this strategy as ill-founded for protecting critical infrastructure. A national strategy that favors the O-side is exactly what asymmetric actors want to see.
[Editor's Note (Assante): Cyber defense investments are a large part of the USG overall spending on cyber. ICS security programs sponsored by DHS and DOE are important contributors to progress, but the real investment needs to occur at the ICS owner-level. The focus of our collective investments matter and Ralph points out the need for skilled people. We are holding the 8th annual SANS SCADA and Process Control Security Summit this February in Orlando with the goal of equipping more cybersecurity professionals and engineers to defend ICS. ]
