In the year 2014, we came to know about the NSA's ability to break Trillions of encrypted connections by exploiting common implementations of the Diffie-Hellman key exchange algorithm – thanks to classified documents leaked by ex-NSA employee Edward Snowden. At that time, computer scientists and senior cryptographers had presented the most plausible theory: Only a few prime numbers were commonly used by 92 percent of the top 1 Million Alexa HTTPS domains that might have fit well within the NSA's $11 Billion-per-year budget dedicated to "groundbreaking cryptanalytic capabilities." And now, researchers from University of Pennsylvania, INRIA, CNRS and Université de Lorraine have practically proved how the NSA broke the most widespread encryption used on the Internet. Diffie-Hellman key exchange (DHE) algorithm is a standard means of exchanging cryptographic keys over untrusted channels, which allows protocols such as HTTPS, SSH, VPN, SMTPS and IPsec to negotia...

Facebook, Instagram, Twitter, VK, Google's Picasa and Youtube were handing over user data access to a Chicago-based Startup — the developer of a social media monitoring tool — which then sold this data to law enforcement agencies for surveillance purposes, the ACLU disclosed Tuesday. Government records obtained by the American Civil Liberties Union (ACLU) revealed that the big technology corporations gave "special access" to Geofeedia. Geofeedia is a controversial social media monitoring tool that pulls social media feeds via APIs and other means of access and then makes it searchable and accessible to its clients, who can search by location or keyword to quickly find recently posted and publicly available contents. The company has marketed its services to 500 law enforcement and public safety agencies as a tool to track racial protests in Ferguson, Missouri, involving the 2014 police shooting death of Mike Brown. With the help of a public records request, the...

Microsoft has released its monthly Patch Tuesday update including a total of 10 security bulletin, and you are required to apply the whole package of patches altogether, whether you like it or not. That's because the company is kicking off a controversial new all-or-nothing patch model this month by packaging all security updates into a single payload, removing your ability to pick and choose which individual patches to install. October's patch bundle includes fixes for at least 5 separate dangerous zero-day vulnerabilities in Internet Explorer, Edge, Windows and Office products that attackers were already exploiting in the wild before the patch release. The patches for these zero-day flaws are included in MS16-118, MS16-119, MS16-120, MS16-121 and MS16-126. All the zero-days are being exploited in the wild, allowing attackers to execute a remote command on victim's system. Although none of the zero-day flaws were publicly disclosed prior to Tuesday, the company wa...

Over the past few years, Internet users globally have grown increasingly aware of online privacy and security issues due to mass monitoring and surveillance by government agencies, making them adopt encryption software and services. But it turns out that hackers are taking advantage of this opportunity by creating and distributing fake versions of encryption tools in order to infect as many victims as possible. Kaspersky Lab has revealed an advanced persistent threat (APT) group, nicknamed StrongPity , which has put a lot of efforts in targeting users of software designed for encrypting data and communications. The StrongPity APT group has been using watering-hole attacks, infected installers, and malware for many years to target users of encryption software by compromising legitimate sites or setting up their own malicious copycat sites. Watering hole attacks are designed to lure specific groups of users to their interest-based sites that typically house malicious files or...
