Some time on Tuesday afternoon, about 50,000 Comcast Internet customers in Houston will become part of a massive public Wi-Fi hotspot network, a number that will swell to 150,000 by the end of June. Comcast will begin activating a feature in its Arris Touchstone Telephony Wireless Gateway Modems that sets up a public Wi-Fi hotspot alongside a residential Internet customer’s private home network. Other Comcast customers will be able to log in to the hotspots for free using a computer, smartphone or other mobile device. And once they log into one, they’ll be automatically logged in to others when their devices “see” them. Comcast says the hotspot – which appears as “xfinitywifi” to those searching for a Wi-Fi connection – is completely separate from the home network. Someone accessing the Net through the hotspot can’t get to the computers, printers, mobile devices, streaming boxes and more sitting on the host network. Comcast officials also say that people using the Internet via the hotspot won’t slow down Internet access on the home network. Additional capacity is allotted to handle the bandwidth. You can read more about Comcast’s reason for doing this in my report on HoustonChronicle.com.

What’s interesting about this move is that, by default, the feature is being turned on without its subscribers’ prior consent. It’s an opt-out system – you have to take action to not participate. Comcast spokesman Michael Bybee said on Monday that notices about the hotspot feature were mailed to customers a few weeks ago, and email notifications will go out after it’s turned on. But it’s a good bet that this will take many Comcast customers by surprise. If you have one of these routers and don’t want to host a public Wi-Fi hotspot, here’s how to turn it off.

The additional capacity for public hotspot users is provided through a separate channel on the modem called a “service flow,” according to Comcast. But the speed of the connection reflects the tier of the subscriber hosting the hotspot. For example, if you connect to a hotspot hosted by a home user with a 25-Mbps connection, it will be slower than if you connect to a host system on the 50-Mbps tier.

Four months from now, at the same time that the National Security Agency finally abandons the massive domestic telephone dragnet exposed by whistleblower Edward Snowden, it will also stop perusing the vast archive of data collected by the program. The NSA announced on Monday that it will expunge all the telephone metadata it previously swept up, citing Section 215 of the U.S.A Patriot Act. The program was ruled illegal by a federal appeals court in May. In June, Congress voted to end the program, but gave the NSA until the end of November to phase it out. The historical metadata —  records of American phone calls showing who called who, when, and for how long — will be put out of the reach of analysts on November 29, although technical personnel will have access for three more months. The program started 14 years ago, and operated under rules requiring data be retained for five years, and then destroyed.

The only possible hold-up, ironically, would be if any of the civil lawsuits prompted by the program prohibit the destruction of the data. “The telephony metadata” will be “preserved solely because of preservation obligations in pending civil litigation,” the Office of the Director of National Intelligence announced. “As soon as possible, NSA will destroy the Section 215 bulk telephony metadata upon expiration of its litigation preservation obligations.” ACLU staff attorney Alex Abdo told The Intercept his organization is “pleased that the NSA intends to purge the call records it has collected illegally.” But, he added: “Even with today’s pledge, the devil may be in the details.”

The ECJ has ruled that governments cannot force telecom firms to keep all customer data. The ruling, which says the laws violate basic privacy rights, comes as governments call for greater powers for spy agencies.

The Court of Justice of the European Union (ECJ) ruled on Wednesday that laws allowing for the blanket collection and retention of location and traffic data are in breach of EU law. In their decision, the justices wrote that storing such data, which includes text message senders and recipients and call histories, allows for "very precise conclusions to be drawn concerning the private lives of the persons whose data has been retained." "Such national legislation exceeds the limits of what is strictly necessary and cannot be considered to be justified within a democratic society," the Luxembourg-based court said. EU member states seeking to fight a "serious crime" are allowed to retain data in a targeted manner but must be subject to prior review by a court or independent body, the EU's top court said. Exceptions can be made in urgent cases. The decision came amidst growing calls from EU governments for security agencies to be given greater powers with the goal of preventing or investigating attacks. Privacy advocates, on the other hand, said mass data retention is ineffective in combating such crimes.

The court's decision was a response to challenges against data retention laws in Britain and Sweden on the ground that they were no longer valid after the court previously struck down an EU-wide data retention law in 2014. In Sweden, the law requires telecommunications companies to retain all their customers' traffic and location data, without exception, the ECJ said. British law allows authorities to ask firms to keep all communication data for a maximum 12-month period. In the UK, politicians filed a legal challenge against a surveillance law which passed in 2014, part of which was suspended by a British court. British lawmakers then passed the Investigatory Powers Act - the so-called "snooper's charter." A German data retention law, which came into effect at the end of 2015, requires telecommunications companies to store telephone and internet use for 10 weeks, after which point the data must be deleted. The German law also stipulates a shorter storage time of four weeks for location data which results from mobile phone calls. It remains to be seen what effect the ECJ ruling will have on Germany's blanket data retention measures.

“Is this related to what we talked about before?” Bencsáth said, referring to a previous discussion they’d had about testing new services the company planned to offer customers. “No, something else,” Bartos said. “Can you come now? It’s important. But don’t tell anyone where you’re going.” Bencsáth wolfed down the rest of his lunch and told his colleagues in the lab that he had a “red alert” and had to go. “Don’t ask,” he said as he ran out the door. A while later, he was at Bartos’ office, where a triage team had been assembled to address the problem they wanted to discuss. “We think we’ve been hacked,” Bartos said.

They found a suspicious file on a developer’s machine that had been created late at night when no one was working. The file was encrypted and compressed so they had no idea what was inside, but they suspected it was data the attackers had copied from the machine and planned to retrieve later. A search of the company’s network found a few more machines that had been infected as well. The triage team felt confident they had contained the attack but wanted Bencsáth’s help determining how the intruders had broken in and what they were after. The company had all the right protections in place—firewalls, antivirus, intrusion-detection and -prevention systems—and still the attackers got in.

Bencsáth was a teacher, not a malware hunter, and had never done such forensic work before. At the CrySyS Lab, where he was one of four advisers working with a handful of grad students, he did academic research for the European Union and occasional hands-on consulting work for other clients, but the latter was mostly run-of-the-mill cleanup work—mopping up and restoring systems after random virus infections. He’d never investigated a targeted hack before, let alone one that was still live, and was thrilled to have the chance. The only catch was, he couldn’t tell anyone what he was doing. Bartos’ company depended on the trust of customers, and if word got out that the company had been hacked, they could lose clients. The triage team had taken mirror images of the infected hard drives, so they and Bencsáth spent the rest of the afternoon poring over the copies in search of anything suspicious. By the end of the day, they’d found what they were looking for—an “infostealer” string of code that was designed to record passwords and other keystrokes on infected machines, as well as steal documents and take screenshots. It also catalogued any devices or systems that were connected to the machines so the attackers could build a blueprint of the company’s network architecture. The malware didn’t immediately siphon the stolen data from infected machines but instead stored it in a temporary file, like the one the triage team had found. The file grew fatter each time the infostealer sucked up data, until at some point the attackers would reach out to the machine to retrieve it from a server in India that served as a command-and-control node for the malware.

A court in the Belgian capital Brussels, on Friday, found the social media company Facebook guilty of breaching Belgian privacy laws. Belgium’s Privacy Commission had taken Facebook to court and the judge agreed with the Commission’s view that Facebook had flouted the country’s privacy legislation. The company has been ordered to correct its practice right away of face fines. Facebook has lodged an appeal.

Facebook follows its users activities by means of so-called social plug-ins, cookies, and pixels. These digital technologies enable Facebook to follow users’ behavior when online. Cookies, for example, are small files that are attached to your internet browser when you go online and visit a particular site. They are used to collect information about the kind of things you like to read or look at while surfing the web. Facebook uses the data both for its own ends, but also to help advertisers send tailor made advertising. In so doing Facebook also uses certain cookies to follow people that don’t even have a Facebook profile. The court ruled that it is “unclear what information Facebook is collecting about us” and “what it uses the information for”. Moreover, Facebook has not been given permission to keep tabs on internet-users by a court of law.

he court has ordered Facebook to stop the practice straight away and to delete any data that it has obtained by means contrary to Belgian privacy legislation. If Facebook fails to comply it will face a penalty payment of 250,000 euro/day.
