Explained: How New 'Delegated Credentials' Boosts TLS Protocol Security

Explained: How New 'Delegated Credentials' Boosts TLS Protocol Security

November 06, 2019Mohit Kumar
Mozilla, in partnership with Facebook, Cloudflare, and other IETF community members, has announced technical specifications for a new cryptographic protocol called " Delegated Credentials for TLS ." Delegated Credentials for TLS is a new simplified way to implement "short-lived" certificates without sacrificing the reliability of secure connections. In short, the new TLS protocol extension aims to effectively prevent the misuse of stolen certificates by reducing their maximum validity period to a very short span of time, such as a few days or even hours. Before jumping into how Delegated Credentials for TLS works, you need to understand the current TLS infrastructure, and of course, about the core problem in it because of which we need Delegated Credentials for TLS. The Current TLS Infrastructure More than 70% of all websites on the Internet today use TLS certificates to establish a secure line of HTTPS communication between their servers and visitors,

New Chrome 0-day Bug Under Active Attacks – Update Your Browser Now!

November 01, 2019Swati Khandelwal
Attention readers, if you are using Chrome on your Windows, Mac, and Linux computers, you need to update your web browsing software immediately to the latest version Google released earlier today. With the release of Chrome 78.0.3904.87, Google is warning billions of users to install an urgent software update immediately to patch two high severity vulnerabilities, one of which attackers are actively exploiting in the wild to hijack computers. Without revealing technical details of the vulnerability, the Chrome security team only says that both issues are use-after-free vulnerabilities, one affecting Chrome's audio component ( CVE-2019-13720 ) while the other resides in the PDFium ( CVE-2019-13721 ) library. The use-after-free vulnerability is a class of memory corruption issues that allows corruption or modification of data in the memory, enabling an unprivileged user to escalate privileges on an affected system or software. Thus, both flaws could enable remote attackers

If you're running any PHP based website on NGINX server and have PHP-FPM feature enabled for better performance, then beware of a newly disclosed vulnerability that could allow unauthorized attackers to hack your website server remotely. The vulnerability, tracked as CVE-2019-11043 , affects websites with certain configurations of PHP-FPM that is reportedly not uncommon in the wild and could be exploited easily as a proof-of-concept (PoC) exploit for the flaw has already been released publicly. PHP-FPM is an alternative PHP FastCGI implementation that offers advanced and highly-efficient processing for scripts written in PHP programming language. The main vulnerability is an "env_path_info" underflow memory corruption issue in the PHP-FPM module, and chaining it together with other issues could allow attackers to remotely execute arbitrary code on vulnerable web servers. The vulnerability was spotted by Andrew Danau, a security researcher at Wallarm while hun
New Cache Poisoning Attack Lets Attackers Target CDN Protected Sites

New Cache Poisoning Attack Lets Attackers Target CDN Protected Sites

October 23, 2019Swati Khandelwal
A team of German cybersecurity researchers has discovered a new cache poisoning attack against web caching systems that could be used by an attacker to force a targeted website into delivering error pages to most of its visitors instead of legitimate content or resources. The issue could affect sites running behind reverse proxy cache systems like Varnish and some widely-used Content Distribution Networks (CDNs) services, including Amazon CloudFront, Cloudflare, Fastly, Akamai, and CDN77. In brief, a Content Distribution Network (CDN) is a geographically distributed group of servers that sit between the origin server of a website and its visitors to optimize the performance of the website. A CDN service simply stores/caches static files—including HTML pages, JavaScript files, stylesheets, images, and videos—from the origin server and delivers them to visitors more quickly without going back to the originating server again and again. Each of the geographically distributed CDN se

Chrome for Android Enables Site Isolation Security Feature for All Sites with Login

October 17, 2019Swati Khandelwal
After enabling ' Site Isolation ' security feature in Chrome for desktops last year, Google has now finally introduced 'the extra line of defence' for Android smartphone users surfing the Internet over the Chrome web browser. In brief, Site Isolation is a security feature that adds an additional boundary between websites by ensuring that pages from different sites end up in different sandboxed processes in the browser. Since each site in the browser gets its own isolated process, in case of a browser flaw or Spectre like side-channel vulnerability, the feature makes it harder for attackers or malicious websites to access or steal cross-site data of your accounts on other websites. Site Isolation helps protect many types of sensitive data, including authentication cookies, stored passwords, network data, stored permissions, as well as cross-origin messaging that help sites securely pass messages across domains. The feature gained attention in January 2018,

Feds Shut Down Largest Dark Web Child Abuse Site; South Korean Admin Arrested

October 17, 2019Swati Khandelwal
The United States Department of Justice said today that they had arrested hundreds of criminals in a global crackdown after taking down the largest known child porn site on the dark web and tracing payments made in bitcoins. With an international coalition of law enforcement agencies, federal officials have arrested the administrator of the child sexual abuse site, 23-year-old Jong Woo Son of South Korea, along with 337 suspects who have been charged for allegedly using the site. The site in question is "Welcome to Video," which operated from June 2015 until March 2018 and hosted over 250,000 sexual exploitation videos of children, toddlers, and infants, which comprised of roughly over 8TB of data. According to a press release published by DoJ, the Welcome to Video site hosted more than 250,000 unique videos, and almost 45 percent of the videos contain new images that have not been previously known to exist. The operation also resulted in the rescue of at least 23

September 18, 2019Wang Wei
A cybersecurity researcher recently published details and proof-of-concept for an unpatched zero-day vulnerability in phpMyAdmin—one of the most popular applications for managing the MySQL and MariaDB databases. phpMyAdmin is a free and open source administration tool for MySQL and MariaDB that's widely used to manage the database for websites created with WordPress, Joomla, and many other content management platforms. Discovered by security researcher and pentester Manuel Garcia Cardenas , the vulnerability claims to be a cross-site request forgery (CSRF) flaw, also known as XSRF, a well-known attack wherein attackers trick authenticated users into executing an unwanted action. Identified as CVE-2019-12922 , the flaw has been given a medium rating because of its limited scope that only allows an attacker to delete any server configured in the setup page of a phpMyAdmin panel on a victim's server. To be noted, it's not something you should not be much worried abo

Google, Mozilla, Apple Block Kazakhstan's Root CA Certificate to Prevent Spying

August 21, 2019Mohit Kumar
In a move to protect its users based in Kazakhstan from government surveillance, Google, Apple and Mozilla finally today came forward and blocked Kazakhstan's government-issued root CA certificate within their respective web browsing software. Starting today, Chrome, Safari and Firefox users in Kazakhstan will see an error message stating that the " Qaznet Trust Network " certificate should not be trusted when attempting to access a website that responds with the government-issued certificate. As The Hacker News reported last month , all major Kazakh Internet Service Providers (ISPs) are forcing their customers into installing a government-issued root certificate on their devices in order to regain access to their Internet services. The root certificate in question, labeled as " trusted certificate " or "national security certificate," if installed, allows ISPs to intercept, monitor, and decrypt users' encrypted HTTPS and TLS connections,
Android Users Can Now Log in to Google Services Using Fingerprint

Android Users Can Now Log in to Google Services Using Fingerprint

August 12, 2019Swati Khandelwal
If you're using Chrome on Android, you can now sign-in to your Google account and some of the other Google services by simply using your fingerprint, instead of typing in your password every time. Google is rolling out a new feature, called " local user verification ," that allows you to log in to both native applications and web services by registering your fingerprint or any other method you've set up to unlock your Android device, including pins, pattern or password. The newly introduced mechanism, which has also been named "verify it's you," takes advantage of Android's built-in FIDO2 certified security key feature that Google rolled out earlier this year to all devices running Android version 7.0 Nougat or later. Besides FIDO2 protocol, the feature also relies on W3C WebAuthn (Web Authentication API) and FIDO Client to Authenticator Protocol (CTAP), which are designed to provide simpler and more secure authentication mechanism that sit

Slack Resets Passwords For Users Who Hadn't Changed It Since 2015 Breach

July 18, 2019Swati Khandelwal
If you use Slack, a popular cloud-based team collaboration server, and recently received an email from the company about a security incident, don't panic and read this article before taking any action. Slack has been sending a "password reset" notification email to all those users who had not yet changed passwords for their Slack accounts since 2015 when the company suffered a massive data breach. For those unaware, in 2015, hackers unauthorisedly gained access to one of the company's databases that stored user profile information, including their usernames, email addresses, and hashed passwords. At that time, attackers also secretly inserted code, probably on the login page, which allowed them to capture plaintext passwords entered by some Slack users during that time. However, immediately following the security incident, the company automatically reset passwords for those small number of Slack users whose plaintext passwords were exposed, but asked other aff

Engage Your Management with the Definitive 'Security for Management' Presentation Template

July 16, 2019The Hacker News
In every organization, there is a person who's directly accountable for cybersecurity. The name of the role varies per the organization's size and maturity – CISO, CIO, and Director of IT are just a few common examples – but the responsibility is similar in all places. They're the person who understands the risk and exposure, knows how prepared the team and most important – what the gaps are and how they can be best addressed. Apart from actually securing the organization – and losing some sleep over it – this individual has another equally important task: to communicate the security risk, needs, and status to the company's management. After all, the level of security rises in direct proportion to the amount of invested resources, and management people are the ones who decide and allocate them. Since management people are not typically cybersecurity savvy, engaging them can be challenging – one must find the balance between high-level explanations, a direct c
17-Year-Old Weakness in Firefox Let HTML File Steal Other Files From Device

17-Year-Old Weakness in Firefox Let HTML File Steal Other Files From Device

July 03, 2019Swati Khandelwal
Except for phishing and scams, downloading an HTML attachment and opening it locally on your browser was never considered as a severe threat until a security researcher today demonstrated a technique that could allow attackers to steal files stored on a victim's computer. Barak Tawily, an application security researcher, shared his findings with The Hacker News, wherein he successfully developed a new proof-of-concept attack against the latest version of Firefox by leveraging a 17-year-old known issue in the browser. The attack takes advantage of the way Firefox implements Same Origin Policy (SOP) for the "file://" scheme URI (Uniform Resource Identifiers), which allows any file in a folder on a system to get access to files in the same folder and subfolders. Since the Same Origin Policy for the file scheme has not been defined clearly in the RFC by IETF, every browser and software have implemented it differently—some treating all files in a folder as the same
