Wij willen met u aan tafel zitten en in een openhartig gesprek uitvinden welke uitdagingen en vragen er bij u spelen om zo, gezamelijk, tot een beste oplossing te komen. Oftewel, hoe kan de techniek u ondersteunen in plaats van dat u de techniek moet ondersteunen.

U.S. security experts are conceding that China has won the race to develop and deploy the 5G telecommunications infrastructure seen as underpinning the next generation of technological advancement and warn that the country and its allies must develop a response — and quickly.

The challenge we have in the development of the 5G network, at least in the early stage, is the dominance of the Huawei firm,” said Tom Ridge, the former US Secretary of Homeland Security and governor of Pennsylvania on a conference call organized recently by Global Cyber Policy Watch. “To embed that technology into a critical piece of infrastructure which is telecom is a huge national security risk.” 

Already some $ 500 million is being allocated to the development of end-to-end encryption software and other technologies through the latest budget for the U.S. Department of Defense, but these officials warn that the money is too little and potentially too late, unless more drastic moves are made.

(You can also hear more about this at TechCrunch Disrupt in SF next week, where we’ll be interviewing startup founders and investors who build businesses by working with governments.)

The problems posed by China’s dominance in this critical component of new telecommunications technologies cut across public and private sector security concerns. They range from intellectual property theft to theft of state secrets and could curtail the ways the U.S. government shares critical intelligence information with its allies, along with opening up the U.S. to direct foreign espionage by the Chinese government, Ridge and other security experts warned.

Last week, users around the world found Wikipedia down after the online, crowdsourced encyclopedia became the target of a massive, sustained DDoS attack — one that it is still actively fighting several days later (even though the site is now back up). Now, in a coincidental twist of timing, Wikipedia’s parent, the Wikimedia Foundation, is announcing a donation aimed at helping the group better cope with situations just like this: Craig Newmark Philanthropies, a charity funded by the Craigslist founder, is giving $ 2.5 million to Wikimedia to help it improve its security.

The gift would have been in the works before the security breach last week, and it underscores a persistent paradox. The non-profit is considered to be one of the 10 most popular sites on the web, with people from some 1 billion different devices accessing it each month, with upwards of 18 billion visits in that period (the latter figure is from 2016 so likely now higher). Wikipedia is used as reference point by millions every day to get the facts on everything from Apple to Zynga, mushrooms and Myanmar history, and as a wiki, it was built from the start for interactivity.

But in this day and age when anything is game for malicious hackers, it’s an easy target, sitting out in the open and generally lacking in the kinds of funds that private companies and other for-profit entities have to protect themselves from security breaches. Alongside networks of volunteers who put in free time to contribute security work to Wikimedia, the  organization only had two people on its security staff two years ago — one of them part-time.

That has been getting fixed, very gradually, by John Bennett, the Wikimedia Foundation’s Director of Security who joined the organization in January 2018, and told TechCrunch in an interview that he’s been working on a more cenrtralised and coherent system, bringing on more staff to help build both tools to combat nefarious activity both on the site and on Wikimedia’s systems; and crucially, put policies in place to help prevent breaches in the future.

“We’ve lived in this bubble of ‘no one is out to get us,’” he said of the general goodwill that surrounds not-for-profit, public organizations like the Wikimedia Foundation. “But we’re definitely seeing that change. We have skilled and determined attackers wishing to do harm to us. So we’re very grateful for this gift to bolster our efforts.

“We weren’t a sitting duck before the breach last week, with a lot of security capabilities built up. But this gift will help improve our posture and build upon on what we started and have been building these last two years.”

The security team collaborates with other parts of the organization to handle some of the more pointed issues. He notes that Wikimedia uses a lot of machine learning that has been developed to monitor pages for vandalism, and an anti-harassment team also works alongside them. (Newmark’s contribution today, in fact, is not the first donation he’s made to the organization. In the past he has donated around $ 2 million towards various projects including the Community Health Initiative, the anti-harassment program; and the more general Wikimedia Endowment).

The security breach that caused the DDoS is currently being responded to by the site reliability engineering team, who are still engaged and monitoring the situation, and Bennett declined to comment more on that.

Zao went viral in China this weekend for its realistic face-swapping videos, but after controversy about its user policy, WeChat restricted access to the app on its messaging platform.

Users can still upload videos they created with Zao to WeChat, but if they try to download the app or send an invite link to another WeChat user, a message is displayed that says “this web page has been reported multiple times and contains security risks. To maintain a safe online environment, access to this page has been blocked.”23011567479434 .pic

Developed by a unit of Momo, one of China’s most popular dating apps, Zao creates videos that replace the faces of celebrities in scenes from popular movies, shows and music videos with a selfie uploaded by the user.

The app, currently available only in China, went viral as users shared their videos through WeChat and other social media platforms in China. But concerns about the potential misuse of deepfake technology coupled with a clause (now deleted) in Zao’s terms of use that gave it full ownership and copyright to content uploaded or created on it, in addition to “completely free, irrevocable, perpetual, transferrable, and re-licensable rights,” caused controversy.

By going viral quickly and being very easy to use (Zao’s videos can be generated from a single selfie, though it suggests that users upload photos from several angles for better results), the app has also focused more attention on deepfake technology and how it can potentially be used to spread misinformation or harass people.

Zao was released last Friday and quickly became the top free iOS app in China, according to App Annie. A statement posted on Sept. 1 to Zao’s Weibo account says “we completely understand everybody’s concerns about the privacy issue. We are aware of the issue and we are thinking about how to fix the problems, we need a little time.” Its terms and conditions now say user-generated content will only be used by the company to improve the app and that all deleted content will be removed from its servers.

TechCrunch has contacted Zao for comment.

If you can’t trust your bank, government or your medical provider to protect your data, what makes you think students are any safer?

Turns out, according to one student security researcher, they’re not.

Eighteen-year-old Bill Demirkapi, a recent high school graduate in Boston, Massachusetts, spent much of his latter school years with an eye on his own student data. Through self-taught pen testing and bug hunting, Demirkapi found several vulnerabilities in a his school’s learning management system, Blackboard, and his school district’s student information system, known as Aspen and built by Follett, which centralizes student data, including performance, grades, and health records.

The former student reported the flaws and revealed his findings at the Def Con security conference on Friday.

“I’ve always been fascinated with the idea of hacking,” Demirkapi told TechCrunch prior to his talk. “I started researching but I learned by doing,” he said.

Among one of the more damaging issues Demirkapi found in Follett’s student information system was an improper access control vulnerability, which if exploited could have allowed an attacker to read and write to the central Aspen database and obtain any student’s data.

Blackboard’s Community Engagement platform had several vulnerabilities, including an information disclosure bug. A debugging misconfiguration allowed him to discover two subdomains, which spat back the credentials for Apple app provisioning accounts for dozens of school districts, as well as the database credentials for most if not every Blackboard’s Community Engagement platform, said Demirkapi.

“School data or student data should be taken as seriously as health data. The next generation should be one of our number one priorities, who looks out for those who can’t defend themselves.”
Bill Demirkapi, security researcher

Another set of vulnerabilities could have allowed an authorized user — like a student — to carry out SQL injection attacks. Demirkapi said six databases could be tricked into disclosing data by injecting SQL commands, including grades, school attendance data, punishment history, library balances, and other sensitive and private data.

Some of the SQL injection flaws were blind attacks, meaning dumping the entire database would have been more difficult but not impossible.

In all, over 5,000 schools and over five million students and teachers were impacted by the SQL injection vulnerabilities alone, he said.

Demirkapi said he was mindful to not access any student records other than his own. But he warned that any low-skilled attacker could have done considerable damage by accessing and obtaining student records, not least thanks to the simplicity of the database’s password. He wouldn’t say what it was, only that it was “worse than ‘1234’.”

But finding the vulnerabilities was only one part of the challenge. Disclosing them to the companies turned out to be just as tricky.

Demirkapi admitted that his disclosure with Follett could have been better. He found that one of the bugs gave him improper access to create his own “group resource,” such as a snippet of text, which was viewable to every user on the system.

“What does an immature 11th grader do when you hand him a very, very, loud megaphone?” he said. “Yell into it.”

And that’s exactly what he did. He sent out a message to every user, displaying each user’s login cookies on their screen. “No worries, I didn’t steal them,” the alert read.

“The school wasn’t thrilled with it,” he said. “Fortunately, I got off with a two-day suspension.”

He conceded it wasn’t one of his smartest ideas. He wanted to show his proof-of-concept but was unable to contact Follett with details of the vulnerability. He later went through his school, which set up a meeting, and disclosed the bugs to the company.

Blackboard, however, ignored Demirkapi’s responses for several months, he said. He knows because after the first month of being ignored, he included an email tracker, allowing him to see how often the email was opened — which turned out to be several times in the first few hours after sending. And yet the company still did not respond to the researcher’s bug report.

Blackboard eventually fixed the vulnerabilities, but Demirkapi said he found that the companies “weren’t really prepared to handle vulnerability reports,” despite Blackboard ostensibly having a published vulnerability disclosure process.

“It surprised me how insecure student data is,” he said. “School data or student data should be taken as seriously as health data,” he said. “The next generation should be one of our number one priorities, who looks out for those who can’t defend themselves.”

He said if a teenager had discovered serious security flaws, it was likely that more advanced attackers could do far more damage.

Heather Phillips, a spokesperson for Blackboard, said the company appreciated Demirkapi’s disclosure.

“We have addressed several issues that were brought to our attention by Mr. Demirkapi and have no indication that these vulnerabilities were exploited or that any clients’ personal information was accessed by Mr. Demirkapi or any other unauthorized party,” the statement said. “One of the lessons learned from this particular exchange is that we could improve how we communicate with security researchers who bring these issues to our attention.”

Follet spokesperson Tom Kline said the company “developed and deployed a patch to address the web vulnerability” in July 2018.

The student researcher said he was not deterred by the issues he faced with disclosure.

“I’m 100% set already on doing computer security as a career,” he said. “Just because some vendors aren’t the best examples of good responsible disclosure or have a good security program doesn’t mean they’re representative of the entire security field.”

Hotstar, India’s largest video streaming service with more than 300 million users, disabled support for Apple’s Safari web browser on Friday to mitigate a security flaw that allowed unauthorized usage of its platform, two sources familiar with the matter told TechCrunch.

The incident comes at a time when the streaming service — operated by Star India, part of 20th Century Fox that Disney acquired — enjoys peak attention as millions of people watch the ongoing ICC World Cup cricket tournament on its platform.

As users began to complain about not being able to use Hotstar on Safari, the company’s official support account asserted that “technical limitations” on Apple’s part were the bottleneck. “These limitations have been from Safari; there is very little we can do on this,” the account tweeted Friday evening.

Sources at Hotstar told TechCrunch that this was not an accurate description of the event. Instead, company’s engineers had identified a security hole that was being exploited by unauthorized users to access Hotstar’s content, they said.

Hotstar intends to work on patching the flaw soon and then reinstate support for Safari, the sources said.

The security flaw can only be exploited through Safari’s desktop and mobile browsers. On its website, the company recommends users to try Chrome and Firefox, or its mobile apps, to access the service. Hotstar did not respond to requests for comment.

Hotstar, which rivals Netflix and Amazon Prime Video in India, maintains a strong lead in the local video streaming market (based on number of users and engagement). Last month, it claimed to set a new global record by drawing more than 18 million viewers to a live cricket match.

Vervuilde data stremt big data analytics

De verwachtingen rondom big data zijn hooggespannen. 74 procent van de West Europese bedrijven verwacht een return on investment (roi) te realiseren binnen twaalf maanden na implementatie van big data analytics. Dat blijkt uit het onderzoek ‘Big Data in Western Europe Today’. uitgevoerd door Forrester Consulting in opdracht van Xerox. Verder laat het onderzoek zien dat vooral een vervuilde database organisaties ervan weerhoudt om big data te omarmen.

Het onderzoek maakt onderscheidt in drie belangrijke trends omtrent de inzet van big data. Zo is big data essentieel bij het nemen van strategische beslissingen. Meer dan de helft van de respondenten (61 procent) geeft aan steeds vaker beslissingen te baseren op datagedreven informatie dan op factoren zoals onderbuikgevoel, mening of zelfs ervaring.  56 procent van de 330 respondenten op managementniveau in Nederland, België, Duitsland, Frankrijk en het Verenigd Koninkrijk ervaart momenteel al voordelen van werken met big data.

Een vervuilde database is kostbaar. Het blijkt dat 70 procent van de organisaties nog steeds onjuiste data ….
