Kanske intressant läsning för fler här på listan. Procera Networks är (var?) svenskbaserat en tid tillbaka.

We are publishing a new Citizen Lab report today, entitled Bad Traffic: Sandvine’s PacketLogic Devices Used to Deploy Government Spyware in Turkey and Redirect Egyptian Users to Affiliate Ads?
Imagine that your device could be silently commandeered and used to spy on you simply because you surfed the web. No need for anyone to have possession of it and physically install something. No need to trick you into downloading spyware, clicking on a malicious link, or entering your credentials into a phony login page. Attackers just wait for you to visit any unencrypted website (http rather than https, that is) and -- boom -- you’re owned.
Now imagine this capability was commercialized and available for sale to operators all over the world...
Imagine no more.
In a new Citizen Lab report, titled Bad Traffic, we present our discovery of how operators appear to use technology manufactured by a company called Sandvine (formerly Procera) to help deliver exactly this type of nation-state malware in Turkey and Syria. Bizarrely, we also discovered that the same Sandvine technology was configured by operators apparently to commandeer unwitting Internet users in Egypt, but not to spy on them. Instead, there we found user requests appeared to have been manipulated by operators to covertly raise money through online ads and cryptocurrency mining scams.
Known as “packet injection,” and undertaken by Deep Packet Inspection (DPI) devices, the techniques we uncovered at work in Turkey and Egypt are similar to those revealed in the Edward Snowden disclosures, codenamed “QUANTUM.” QUANTUM attacks are considered among the most powerful weapons in the NSA’s (and its Five Eyes allies’) toolkit. One was reportedly employed by the UK’s GCHQ to get inside the computers of Belgium’s largest telco, Belgacom, by redirecting senior Belgacom technicians to fake Linkedin pages where their computers were silently infected with malware. As the Belgacom operation demonstrates, QUANTUM attacks typically involve two components: a first, where packets are injected into Internet requests; and a second, in which a separate server controlled by the attackers (codenamed FOXACID by the NSA) injects spyware. We found Sandvine Packetlogic devices were being used by operators to perform the first component, with spyware of the operator’s choice (presumably Turkish authorities) involved in the second.
Pulling off a QUANTUM attack is relatively simple if you control the network of a group of users. Computer scientist Nick Weaver demonstrated a QUANTUM attack at our 2015 Citizen Lab Summer Institute. However, to be able to execute QUANTUM attacks at the national scale requires control or cooperation of a major telecommunications provider, something only national governments can practically do.
In another Snowden disclosure, Canada’s spy agency, CSE, noted in a top-secret presentation that “it’s no lie, quantum is cool,” but then added “it’s easy to find.” Well, maybe for them. For researchers like us, it’s not so easy. Our report is the first case where nation-state spyware injection has been empirically documented “in the wild.” Credit goes to the Citizen Lab’s Bill Marczak, whose remarkable detective work included scanning every one of the billions of IPv4 addresses on the Internet to search for the unique fingerprint he developed for Sandvine’s PacketLogic device. We also verified the fingerprint in a laboratory setting using a second-hand PacketLogic device we purchased. Marczak’s sleuthing identified spyware injection targeting Türk Telekom subscribers in at least five provinces in Turkey, and hundreds of users across the border in Syria who were receiving their Internet access through WiFi connection points leased from Türk Telekom. The same methods helped uncover the Egyptian mass injections for profit scheme, which we have dubbed “AdHose”.
One imagines that the NSA, GCHQ, and their allies spent many years and considerable scientific and financial resources developing QUANTUM capabilities in house. Today, commercial DPI technology combined with spyware in the ways we have documented allows a government to simply order them up. With QUANTUM-as-a-Service, many more governments will now be playing in the Five Eyes’ league — governments like Turkey and Egypt, which Human Rights Watch describes respectively as “the world leader in jailing journalists and media workers,” and “continuing near-absolute impunity for abuses by security forces under the pretext of fighting ‘terrorism.’”
The prospect of QUANTUM capabilities being sold “off-the-shelf” to any government or government-controlled telco should give everyone pause, especially because the type of DPI sold by companies like Sandvine, as currently advertised, falls through the regulatory cracks. It is classic “dual-use” technology, marketed as benign-sounding “quality of service” or “quality of experience” functionality: helping Internet Service Providers manage network traffic, speed up the delivery of videos for higher-paying clients, and block forbidden applications. The 51 member-state, dual-use technology Wassenaar Arrangement targets “IP network communications surveillance” items for export controls, but specifically exempts “quality of service” and “quality of experience” systems. However, as our report shows, Sandvine’s technology (which appears at present to fall under this exemption) can also surreptitiously redirect users to sophisticated spyware, or permit the hijacking of browsers to mine cryptocurrency for profit. Its power is in the hands of the local operator — operators that answer to autocratic rulers like Turkey’s Erdogan or Egypt’s el-Sisi.
It is worth noting that Sandvine is owned by Francisco Partners, the same investment group that also happens to own Israeli spyware vendor NSO Group, another company whose misused services have been the subject of numerous Citizen Lab reports. In response to our letters to these companies, Sandvine and Francisco Partners both claimed that they have stringent business ethics and other internal checks to prevent abuse of their services. Not good enough checks, it seems.
Until its acquisition by Francisco Partners last year, and its subsequent combination with Procera, Sandvine was headquartered in Waterloo, Canada. At the time of the proposed sale, I argued that the takeover warranted closer scrutiny by the federal government. In light of Citizen Lab’s report, I wonder if anything will be done by relevant authorities in Canada and the United States? Targeted injection of spyware at the nation-state level represents a major public safety risk, and technologies that facilitate such injection should be regulated accordingly.
While we wait for governments to act, there’s more that can be done right now to protect users. Properly encrypting websites by default would certainly frustrate these sorts of attacks. However, Google and Firefox stats show around 20-30% of all websites are still not encrypted by default. That needs to change.
Until such time, keep an eye out for the headers of the websites you visit. If it reads “http” without the “s”, and there’s no little lock icon up in the address bar that says “secure,” you too may be vulnerable to this type of attack.
All the best
