Internet service providers from around the world are lodging formal complaints against the UK government's monitoring service, GCHQ, alleging that it uses "malicious software" to break into their networks.The claims from seven organisations based in six countries – the UK, Netherlands, US, South Korea, Germany and Zimbabwe – will add to international pressure on the British government following Edward Snowden's revelations about mass surveillance of the internet by UK and US intelligence agencies.The claims are being filed with the investigatory powers tribunal (IPT), the court in London that assesses complaints about the agencies' activities and misuse of surveillance by government organisations. Most of its hearings are held at least partially in secret.

The IPT is already considering a number of related submissions. Later this month it will investigate complaints by human rights groups about the way social media sites have been targeted by GCHQ.The government has defended the security services, pointing out that online searches are often routed overseas and those deemed "external communications" can be monitored without the need for an individual warrant. Critics say that such a legal interpretation sidesteps the need for traditional intercept safeguards.The latest claim is against both GCHQ, located near Cheltenham, and the Foreign Office. It is based on articles published earlier this year in the German magazine Der Spiegel. That report alleged that GCHQ had carried out an attack, codenamed Operation Socialist, on the Belgian telecoms group, Belgacom, targeting individual employees with "malware (malicious software)".One of the techniques was a "man in the middle" attack, which, according to the documents filed at the IPT, bypasses modern encryption software and "operates by interposing the attacker [GCHQ] between two computers that believe that they are securely communicating with each other. In fact, each is communicating with GCHQ, who collect the communications, as well as relaying them in the hope that the interference will be undetected."The complaint alleges that the attacks were a breach of the Computer Misuse Act 1990 and an interference with the privacy rights of the employees under the European convention of human rights.

The organisations targeted, the submission states, were all "responsible and professional internet service providers". The claimants are: GreenNet Ltd, based in the UK, Riseup Networks in Seattle, Mango Email Service in Zimbabwe, Jinbonet in South Korea, Greenhost in the Netherlands, May First/People Link in New York and the Chaos Computer Club in Hamburg.

If we’ve learned one thing from the Snowden revelations, it’s that what can be spied on will be spied on. Since the advent of what used to be known as the World Wide Web, it has been a relatively simple matter for network attackers—whether it’s the NSA, Chinese intelligence, your employer, your university, abusive partners, or teenage hackers on the same public WiFi as you—to spy on almost everything you do online. HTTPS, the technology that encrypts traffic between browsers and websites, fixes this problem—anyone listening in on that stream of data between you and, say, your Gmail window or bank’s web site would get nothing but useless random characters—but is woefully under-used. The ambitious new non-profit Let’s Encrypt aims to make the process of deploying HTTPS not only fast, simple, and free, but completely automatic. If it succeeds, the project will render vast regions of the internet invisible to prying eyes.

Encryption also prevents attackers from tampering with or impersonating legitimate websites. For example, the Chinese government censors specific pages on Wikipedia, the FBI impersonated The Seattle Times to get a suspect to click on a malicious link, and Verizon and AT&T injected tracking tokens into mobile traffic without user consent. HTTPS goes a long way in preventing these sorts of attacks. And of course there’s the NSA, which relies on the limited adoption of HTTPS to continue to spy on the entire internet with impunity. If companies want to do one thing to meaningfully protect their customers from surveillance, it should be enabling encryption on their websites by default.

Let’s Encrypt, which was announced this week but won’t be ready to use until the second quarter of 2015, describes itself as “a free, automated, and open certificate authority (CA), run for the public’s benefit.” It’s the product of years of work from engineers at Mozilla, Cisco, Akamai, Electronic Frontier Foundation, IdenTrust, and researchers at the University of Michigan. (Disclosure: I used to work for the Electronic Frontier Foundation, and I was aware of Let’s Encrypt while it was being developed.) If Let’s Encrypt works as advertised, deploying HTTPS correctly and using all of the best practices will be one of the simplest parts of running a website. All it will take is running a command. Currently, HTTPS requires jumping through a variety of complicated hoops that certificate authorities insist on in order prove ownership of domain names. Let’s Encrypt automates this task in seconds, without requiring any human intervention, and at no cost.

Complex malware known as Regin is the suspected technology behind sophisticated cyberattacks conducted by U.S. and British intelligence agencies on the European Union and a Belgian telecommunications company, according to security industry sources and technical analysis conducted by The Intercept. Regin was found on infected internal computer systems and email servers at Belgacom, a partly state-owned Belgian phone and internet provider, following reports last year that the company was targeted in a top-secret surveillance operation carried out by British spy agency Government Communications Headquarters, industry sources told The Intercept. The malware, which steals data from infected systems and disguises itself as legitimate Microsoft software, has also been identified on the same European Union computer systems that were targeted for surveillance by the National Security Agency.

The hacking operations against Belgacom and the European Union were first revealed last year through documents leaked by NSA whistleblower Edward Snowden. The specific malware used in the attacks has never been disclosed, however.
