This week, it was revealed that as a result of a secret US government directive, Yahoo was forced to implement special surveillance software to scan all Yahoo Mail accounts at the request of the NSA and FBI. Sometime in early 2015, Yahoo secretly modified their spam and malware filters to scan all incoming email messages for the phrases in the court order and then siphoned those messages off to US intelligence. This is significant for several reasons:
This is a terrible precedent and ushers in a new era of global mass surveillance. It means that US tech companies that serve billions of users around the world can now be forced to act as extensions of the US surveillance apparatus. The problem extends well beyond Yahoo. As was reported earlier, Yahoo did not fight the secret directive because Yahoo CEO Marissa Mayer and the Yahoo legal team did not believe that they could successfully resist the directive.
We believe that Yahoo’s assessment is correct. If it was possible to fight the directive, Yahoo certainly would have done so since they previously fought against secret FISA court orders in 2008. It does not make sense that US surveillance agencies would serve Yahoo Mail with such an order but ignore Gmail, the world’s largest email provider, or Outlook. There is no doubt that the secret surveillance software is also present in Gmail and Outlook, or at least there is nothing preventing Gmail and Outlook from being forced to comply with a similar directive in the future. From a legal perspective, there is nothing that makes Yahoo particularly vulnerable, or Google particularly invulnerable.
Google and Microsoft have come out to deny they participated in US government mandated mass surveillance, but under a National Security Letter (NSL) gag order, Google and Microsoft would have no choice but to deny the allegations or risk breaking US law (our analysis of Yahoo’s denial is at the bottom of this post). Again ,there is no conceivable reason US intelligence would target Yahoo but ignore Gmail, so we must consider this to be the most probable scenario, particularly since gag orders have become the norm rather than the exception.
In effect, the US government has now officially co-opted US tech companies to perform mass surveillance on all users, regardless of whether they are under US jurisdiction or not. Given the huge amount of data that Google has, this is a truly scary proposition.
Onionbit’s secure email service is based in Switzerland and all our servers are located in Switzerland, so all user data is maintained under the protection of Swiss privacy laws. Onionbit cannot be compelled to perform mass surveillance on our users, nor be compelled to act on behalf of US intelligence. Onionbit also utilizes end-to-end encryption which means we do not have the capability to read user emails in the first place, so we couldn’t hand over user email data even if we wanted to.
However, since email is an open system, any unencrypted email that goes out of Onionbit, to Yahoo Mail for example, could potentially have been swept up by these mass surveillance programs and sent to US government agencies. This is why if you want to avoid having your communications scanned and saved by US government agencies, it is important to invite friends, family, and colleagues to use non-US email accounts such as Onionbit or other email services offered by European companies.
Unfortunately, the tech sector today is entirely dominated by US companies. Just like Google has a monopoly on search, the US government has a near monopoly on mass surveillance. Even without US government pressure, most US tech companies also have perverse economic incentives to slowly chip away at digital privacy.
This week, we have again seen how easily the massive amounts of private data retained by US tech companies can be abused by US intelligence for their own purposes. Without alternatives to the US tech giants, the rest of the world has no choice but to consent to this. This is an unprecedented challenge, but it also presents an unprecedented opportunity, particularly for Europe.
Now is the time for Europe to invest in its own tech sector, unbeholden to outside interests. This is the only way the European community can continue to safeguard the European ideals of privacy, liberty, and freedom online. It is time for European governments and citizens to act before it is too late.
The only chance for privacy to prevail against these attacks is for the global community to support a new generation of web services which protect privacy by default. These services, such as Onionbit’s encrypted email service, must operate with a business model where users can donate or pay for services, instead of giving up data and privacy. The security community also has an obligation to make these new service just as easy to use as the ones they replace.
