Comments Off on NSA Spies With Tracking Cookies
The browser cookies that online businesses use to track Internet customers for targeted advertising are also used by the National Security Agency to track surveillance targets and break into their systems.
The agency’s use of browser cookies is restricted to tracking specific suspects rather than sifting through vast amounts of user data, theWashington Post reported Tuesday, citing internal documents obtained from former NSA contractor Edward Snowden.
Google’s PREF (for preference) cookies, which the company uses to personalize webpages for Internet users based on their previous browsing habits and preferences, appears to be a particular favorite of the NSA, the Post noted.
PREF cookies don’t store any user identifying information such as user name or email address. But they contain information on a user’s general location, language preference, search engine settings, number of search results to display per page and other data that lets advertisers uniquely identify an individual’s browser.
The Google cookie, and those used by other online companies, can be used by the NSA to track a target user’s browsing habits and to enable remote exploitation of their computers, the Post said.
Documents made available by Snowden do not describe the specific exploits used by the NSA to break into a surveillance target’s computers. Neither do they say how the NSA gains access to the tracking cookies, the Post reported.
It is theorized that one way the NSA could get access to the tracking cookies is to simply ask the companies for them under the authority granted to the agency by the Foreign Intelligence Surveillance Act (FISA).
Separately, the documents leaked by Snowden show that the NSA is also tapping into cell-phone location data gathered and transmitted by makers of mobile applications and operating systems. Google and other Internet companies use the geo-location data transmitted by mobile apps and operating systems to deliver location-aware advertisements and services to mobile users.
However, the NSA is using the same data to track surveillance targets with more precision than was possible with data gathered directly from wireless carriers, the Post noted. The mobile app data, gathered by the NSA under a program codenamed “Happyfoot,” allows the agency to tie Internet addresses to physical locations more precisely than was possible with cell-phone location data.
An NSA division called Tailored Access Operations uses the data gathered from tracking cookies and mobile applications to launch offensive hacking operations against specific target computers, the Post said.
An NSA spokeswoman Wednesday did not comment on the specific details in the Post story but reiterated the agency’s commitment to fulfill its mission of protecting the country against those seeking to do it harm.
“As we’ve said before, NSA, within its lawful mission to collect foreign intelligence to protect the United States, uses intelligence tools to understand the intent of foreign adversaries and prevent them from bringing harm to innocent Americans and allies,” the spokeswoman said.
The Post’s latest revelations are likely to shine a much-needed spotlight on the extensive tracking and monitoring activities carried out by major Internet companies in order to deliver targeted advertisements to users.
Privacy rights groups have protested such tracking for several years and have sought legislation that would give users more visibility and control over the data that is collected on them by online companies.
Twitter Tightens Security
Twitter Inc said it has put in place a security technology that makes it harder to spy on its users and called on other Internet firms to do the same, as Web providers look to thwart spying by government intelligence agencies.
The online messaging service, which began scrambling communications in 2011 using traditional HTTPS encryption, said on Friday it has added an advanced layer of protection for HTTPS known as “forward secrecy.”
“A year and a half ago, Twitter was first served completely over HTTPS,” the company said in a blog posting. “Since then, it has become clearer and clearer how important that step was to protecting our users’ privacy.”
Twitter’s move is the latest response from U.S. Internet firms following disclosures by former spy agency contractor Edward Snowden about widespread, classified U.S. government surveillance programs.
Facebook Inc, Google Inc, Microsoft Corp and Yahoo Inc have publicly complained that the government does not let them disclose data collection efforts. Some have adopted new privacy technologies to better secure user data.
Forward secrecy prevents attackers from exploiting one potential weakness in HTTPS, which is that large quantities of data can be unscrambled if spies are able to steal a single private “key” that is then used to encrypt all the data, said Dan Kaminsky, a well-known Internet security expert.
The more advanced technique repeatedly creates individual keys as new communications sessions are opened, making it impossible to use a master key to decrypt them, Kaminsky said.
“It is a good thing to do,” he said. “I’m glad this is the direction the industry is taking.”
Is Skype Involved In Spying?
Luxembourg’s data protection authority is investigating Microsoft-owned Skype for its alleged cooperation with the U.S. NSA’s Prism spying program, according to the agency.
Luxembourg’s data protection authority, CNPD, is investigating Skype’s links to NSA spying programs after receiving several complaints, said Tom Kayser, a spokesman for the authority. “I can’t really talk about the details of the investigation because it is still ongoing,” he said.
Skype, which has its European headquarters in Luxembourg, allegedly cooperates with the NSA through a program exploring the legal and technical issues involved in making customer calls available to intelligence and law enforcement agencies. The Guardian newspaper first reported the investigation.
The CNPD has powers to ensure that multinational companies based in Luxembourg respect national law, and often receives complaints from the data protection authorities of other European Union member states.
Privacy campaign group Europe-v-Facebook filed one of the complaints in June. That filing was part of a barrage of complaints filed in various countries against European subsidiaries of tech companies that are allegedly involved in the NSA’s spying program, including Facebook, Apple, Microsoft and Yahoo.
Under Luxembourg data protection law service providers and operators are required to ensure the confidentiality of communications and related traffic data.
“No person other than the user concerned may listen to, tap or store communications or the traffic data relating thereto, or engage in any other kinds of interception or surveillance thereof, without the consent of the user concerned,” reads the law’s unofficial English translation.
Violators can face up to a year in prison and/or a fine up to a!125,000 ($170,000). The court dealing with the matter can also order companies like Skype to stop any processing that conflicts with the law on pain of a periodic monetary penalty determined by the court.
“We regularly engage in a dialogue with data protection authorities around the world and are always happy to answer their questions,” a Microsoft spokeswoman said in an email. “It has been previously widely reported that the Luxembourg DPA was one of the DPA’s that received complaints from the ‘Europe v Facebook’ group so we’re happy to answer any questions they may have.”
U.S. Cloud Vendors Hurt By NSA
Edward Snowden’s public unveiling of the National Security Agency’s Prism surveillance program could cause U.S. providers of cloud-based services to lose 10% to 20% of the foreign market — a slice of business valued at up to $35 billion.
A new report from the Information Technology & Innovation Foundation (ITIF) concludes that European cloud computing companies, in particular, might successfully exploit users’ fears about the secret data collection program to challenge U.S. leadership in the hosted services business.
Daniel Castro, author of the report, acknowledges that the conclusions are based, so far, on thin data, but nonetheless argues that the risks to U.S. cloud vendors are real.
Indeed, a month prior, the Cloud Security Alliance reported that in a survey of 207 officials of non-U.S. companies, 10% of the respondents said that they had canceled contracts with U.S. service providers after Snowden’s leak of NSA Prism documents earlier this year.
“If U.S. companies lose market share in the short term, it will have long-term implications on their competitive advantage in this new industry,” said Castro in the ITIF report. “Rival countries have noted this opportunity and will try to exploit it.”
To counter such efforts, the U.S. must challenge overstated claims about the program by foreign companies and governments, said Jason Weinstein, a partner in the Washington office of law firm Steptoe & Johnson and a former federal prosecutor and deputy assistant attorney general specializing in computer crime.
“There are a lot of reasons to be concerned about just how significant those consequences will be,” Weinstein said. “The effort by European governments and European cloud providers to cloud the truth about data protection in the U.S. was going on well before anyone knew who Edward Snowden was. It just picked up new momentum once the Prism disclosures came out.”
Weinstein contends that European countries have fewer data protection rules than the U.S.
For example, he said that in the U.K. and France, a wiretap to get content can be issued by a government official without court authority, but that can’t happen in the U.S.
“U.S. providers have done nothing other than comply with their legal obligations,” he said. But because of Snowden’s leaks, “they are facing potentially significant economic consequences.”
Gartner analyst Ed Anderson said his firm has yet to see any revenue impact on cloud providers since the Prism disclosures, but added, “I don’t think Prism does U.S. providers any favors, that’s for sure.”
Nonetheless, Anderson added, “I think the reality is [the controversy] is likely to die down over time, and we expect adoption to probably continue on the path that it has been on.”
One reason why U.S. providers may not suffer is because “the alternatives aren’t great if you are a European company looking for a cloud service,” he said.
FTC Warns Google And FB

Comments Off on FTC Warns Google And FB
The Federal Trade Commission (FTC) has promised that her organisation will come down hard on companies that do not meet requirements for handling personal data.
FTC Chairwoman Edith Ramirez gave a keynote speech at the Technology Policy Institute at the Aspen Forum. She said that the FTC has a responsibility to protect consumers and prevent them from falling victim to unfair commercial practices.
“In the FTC’s actions against Google, Facebook, Myspace and others, we alleged that each of these companies deceived consumers by breaching commitments to keep their data confidential. That isn’t okay, and it is the FTC’s responsibility to make sure that companies live up to their commitments,” she said.
“All told, the FTC has brought over 40 data security cases under our unfairness and deception authority, many against very large data companies, including Lexisnexis, Choicepoint and Twitter, for failing to provide reasonable security safeguards.”
Ramirez spoke about the importance of consumer privacy, saying that there is too much “shrouding” of what happens in that area. She said that under her leadership the FTC will not be afraid of suing companies when it sees fit.
“A recurring theme I have emphasized – and one that runs through the agency’s privacy work – is the need to move commercial data practices into the sunlight. For too long, the way personal information is collected and used has been at best an enigma enshrouded in considerable smog. We need to clear the air,” she said.
Ramirez compared the work of the FTC to the work carried out by lifeguards, saying that it too has to be vigilant.
“Lifeguards have to be mindful not just of the people swimming, surfing, and playing in the sand. They also have to be alert to approaching storms, tidal patterns, and shifts in the ocean’s current. With consumer privacy, the FTC is doing just that – we are alert to the risks but confident that those risks can be managed,” she added.
“The FTC recognizes that the effective use of big data has the potential to unleash a new wave of productivity and growth. Like the lifeguard at the beach, though, the FTC will remain vigilant to ensure that while innovation pushes forward, consumer privacy is not engulfed by that wave.”
It’s all just lip service, of course. Companies might be nominally bound by US privacy laws in online commerce, and that might be overseen by the FTC, but the US National Security Agency (NSA) collects all internet traffic anyway, and makes data available to other US government agencies and even some private companies.
Google Encrypts Data

Comments Off on Google Encrypts Data
Google officially announced it will by default encrypt data warehoused in its Cloud Storage service.
The server-side encryption is now active for all new data written to Cloud Storage, and older data will be encrypted in the coming months, wrote Dave Barth, a Google product manager, in a blog post.
“If you require encryption for your data, this functionality frees you from the hassle and risk of managing your own encryption and decryption keys,” Barth wrote. “We manage the cryptographic keys on your behalf using the same hardened key management systems that Google uses for our own encrypted data, including strict key access controls and auditing.”
The data and metadata around an object stored in Cloud Storage is encrypted with a unique key using 128-bit Advanced Encryption Standard algorithm, and the “per-object key itself is encrypted with a unique key associated with the object owner,” Barth wrote.
“These keys are additionally encrypted by one of a regularly rotated set of master keys,” he wrote. “Of course, if you prefer to manage your own keys then you can still encrypt data yourself prior to writing it to Cloud Storage.”
Data collection programs revealed by former U.S. National Security Agency contractor Edward Snowden have raised questions about U.S. government data requests made to Internet companies such as Google for national security investigations.
A Google spokeswoman said via email the company does not provide encryption keys to any government and provides user data only in accordance with the law.
“Our legal team reviews each and every request, and we frequently push back when the requests appear to be fishing expeditions or don’t follow the correct process,” she wrote. “When we are required to comply with these requests, we deliver it to the authorities. No government has the ability to pull data directly from our servers or network.”
