New Google Chrome Zero-Day Vulnerability Found Actively Exploited in the Wild

March 06, 2019Mohit Kumar
You must update your Google Chrome immediately to the latest version of the web browsing application. Security researcher Clement Lecigne of Google's Threat Analysis Group discovered and reported a high severity vulnerability in Chrome late last month that could allow remote attackers to execute arbitrary code and take full control of the computers. The vulnerability, assigned as CVE-2019-5786 , affects the web browsing software for all major operating systems including Microsoft Windows, Apple macOS, and Linux. Without revealing technical details of the vulnerability, the Chrome security team only says the issue is a use-after-free vulnerability in the FileReader component of the Chrome browser, which leads to remote code execution attacks. What's more worrisome? Google warned that this zero-day RCE vulnerability is actively being exploited in the wild by attackers to target Chrome users. "Access to bug details and links may be kept restricted until a majo
New Flaws Re-Enable DMA Attacks On Wide Range of Modern Computers

New Flaws Re-Enable DMA Attacks On Wide Range of Modern Computers

February 27, 2019Mohit Kumar
Security researchers have discovered a new class of security vulnerabilities that impacts all major operating systems, including Microsoft Windows, Apple macOS, Linux, and FreeBSD, allowing attackers to bypass protection mechanisms introduced to defend against DMA attacks. Known for years, Direct memory access (DMA)-based attacks let an attacker compromise a targeted computer in a matter of seconds by plugging-in a malicious hot plug device—such as an external network card, mouse, keyboard, printer, storage, and graphics card—into Thunderbolt 3 port or the latest USB-C port . The DMA-based attacks are possible because Thunderbolt port allows connected peripherals to bypass operating system security policies and directly read/write system memory that contains sensitive information including your passwords, banking logins, private files, and browser activity. That means, simply plugging in an infected device, created using tools like Interception , can manipulate the contents o

Hacking Virtual Reality – Researchers Exploit Popular Bigscreen VR App

February 22, 2019Mohit Kumar
A team of cybersecurity researchers from the University of New Haven yesterday released a video demonstrating how vulnerabilities that most programmers often underestimate could have allowed hackers to evade privacy and security of your virtual reality experience as well as the real world. According to the researchers—Ibrahim Baggili, Peter Casey and Martin Vondráček—the underlying vulnerabilities, technical details of which are not yet publicly available but shared exclusively with The Hacker News , resided in a popular virtual reality (VR) application called Bigscreen and the Unity game development platform, on which Bigscreen is built. Bigscreen is a popular VR application that describes itself as a "virtual living room," enabling friends to hang out together in virtual world, watch movies in a virtual cinema, chat in the lobby, make private rooms, collaborate on projects together, share their computer screens or control in a virtual environment and more.

Another Critical Flaw in Drupal Discovered — Update Your Site ASAP!

February 21, 2019Wang Wei
Developers of Drupal—a popular open-source content management system software that powers millions of websites—have released the latest version of their software to patch a critical vulnerability that could allow remote attackers to hack your site. The update came two days after the Drupal security team released an advance security notification of the upcoming patches, giving websites administrators early heads-up to fix their websites before hackers abuse the loophole. The vulnerability in question is a critical remote code execution (RCE) flaw in Drupal Core that could "lead to arbitrary PHP code execution in some cases," the Drupal security team said. While the Drupal team hasn't released any technical details of the vulnerability (CVE-2019-6340), it mentioned that the flaw resides due to the fact that some field types do not properly sanitize data from non-form sources and affects Drupal 7 and 8 Core. It should also be noted that your Drupal-based website
Warning: Critical WinRAR Flaw Affects All Versions Released In Last 19 Years

Warning: Critical WinRAR Flaw Affects All Versions Released In Last 19 Years

February 21, 2019Swati Khandelwal
Beware Windows users... a new dangerous remote code execution vulnerability has been discovered in the WinRAR software, affecting hundreds of millions of users worldwide. Cybersecurity researchers at Check Point have disclosed technical details of a critical vulnerability in WinRAR—a popular Windows file compression application with 500 million users worldwide—that affects all versions of the software released in last 19 years. The flaw resides in the way an old third-party library, called UNACEV2.DLL, used by the software handled the extraction of files compressed in ACE data compression archive file format. However, since WinRAR detects the format by the content of the file and not by the extension, attackers can merely change the .ace extension to .rar extension to make it look normal. According to researchers, they found an "Absolute Path Traversal" bug in the library that could be leveraged to execute arbitrary code on a targeted system attempting to uncompre

Critical Flaw Uncovered In WordPress That Remained Unpatched for 6 Years

February 19, 2019Swati Khandelwal
Exclusive — If you have not updated your website to the latest WordPress version 5.0.3, it’s a brilliant idea to upgrade the content management software of your site now. From now, I mean immediately. Cybersecurity researchers at RIPS Technologies GmbH today shared their latest research with The Hacker News, revealing the existence of a critical remote code execution vulnerability that affects all previous versions of WordPress content management software released in the past 6 years. The remote code execution attack, discovered and reported to the WordPress security team late last year, can be exploited by a low privileged attacker with at least an "author" account using a combination of two separate vulnerabilities—Path Traversal and Local File Inclusion—that reside in the WordPress core. The requirement of at least an author account reduces the severity of this vulnerability to some extent, which could be exploited by a rogue content contributor or an attacker w

How to Hack Facebook Accounts? Just Ask Your Targets to Open a Link

February 18, 2019Mohit Kumar
It's 2019, and just clicking on a specially crafted URL would have allowed an attacker to hack your Facebook account without any further interaction. A security researcher discovered a critical cross-site request forgery (CSRF) vulnerability in the most popular social media platform that could have been allowed attackers to hijack Facebook accounts by simply tricking the targeted users into clicking on a link. The researcher, who goes by the online alias "Samm0uda," discovered the vulnerability after he spotted a flawed endpoint (facebook.com/comet/dialog_DONOTUSE/) that could have been exploited to bypass CSRF protections and takeover victim's account. "This is possible because of a vulnerable endpoint which takes another given Facebook endpoint selected by the attacker along with the parameters and makes a POST request to that endpoint after adding the fb_dtsg parameter," the researcher says on his blog . "Also this endpoint is located under t

Snapd Flaw Lets Attackers Gain Root Access On Linux Systems

February 13, 2019Mohit Kumar
Ubuntu and some other Linux distributions suffer from a severe privilege escalation vulnerability that could allow a local attacker or a malicious program to obtain root privileges and total control over the targeted system. Dubbed " Dirty_Sock " and identified as CVE-2019-7304 , the vulnerability was discovered by security researcher Chris Moberly, who privately disclosed it to Canonical, the maker of Ubuntu, late last month. The vulnerability resides in the REST API for snapd service , a universal Linux packaging system that makes an application compatible for various Linux distributions without requiring any modification. Built by Canonical, snapd comes by default installed on all versions of Ubuntu and also used by other Linux distributions, including Debian, OpenSUSE, Arch Linux, Solus, and Fedora. Snap packages are basically applications compressed together with their dependencies that also includes instructions on how to run and interact with other software o

Latest iOS 12.1.4 Update Patches 2 Zero-Day and FaceTime Bugs

February 08, 2019Swati Khandelwal
Apple has finally released iOS 12.1.4 software update to patch the terrible Group FaceTime privacy bug that could have allowed an Apple user to call you via the FaceTime video chat service and hear or see you before you even pick up the call without your knowledge. The Facetime bug (CVE-2019-6223) was discovered by 14-year-old Grant Thompson of Catalina Foothills High School while he was trying to set up a Group FaceTime session with his friends. Thompson reported the bug to the company a week before it made headlines across the internet, forcing Apple to temporarily disable the group calling feature within FaceTime. In its advisory published Thursday, Apple described the bug as "a logic issue existed in the handling of Group FaceTime calls," that also impacted the group FaceTime calling feature on Apple's macOS Mojave 10.14.2. Along with Thompson, Apple has also credited Daven Morris of Arlington, Texas, in its official advisory for reporting this bug. Acc

Using an Android device? Beware! You have to remain more caution while opening an image file on your smartphone—downloaded anywhere from the Internet or received through messaging or email apps. Yes, just viewing an innocuous-looking image could hack your Android smartphone—thanks to three newly-discovered critical vulnerabilities that affect millions of devices running recent versions of Google's mobile operating system, ranging from Android 7.0 Nougat to its current Android 9.0 Pie. The vulnerabilities, identified as CVE-2019-1986, CVE-2019-1987, and CVE-2019-1988, have been patched in Android Open Source Project (AOSP) by Google as part of its February Android Security Updates . However, since not every handset manufacturer rolls out security patches every month, it's difficult to determine if your Android device will get these security patches anytime sooner. Although Google engineers have not yet revealed any technical details explaining the vulnerabilities, t
Critical Zcash Bug Could Have Allowed 'Infinite Counterfeit' Cryptocurrency

Critical Zcash Bug Could Have Allowed 'Infinite Counterfeit' Cryptocurrency

February 06, 2019Swati Khandelwal
The developers behind the privacy-minded Zcash cryptocurrency have recently discovered and patched a highly dangerous vulnerability in the most secretive way that could have allowed an attacker to coin an infinite number of Zcash (ZEC). Yes, infinite… like a never-ending source of money. Launched in October 2016, Zcash is a privacy-oriented cryptocurrency that claims to be more anonymous than Bitcoin, as the sender, recipient, and value of transactions remain hidden. In a blog post published today, the Zerocoin Electric Coin Company—the startup behind Zcash—revealed that one of its employees, Ariel Gabizon, discovered the vulnerability in its code on 1st March 2018, the night prior to his talk at the Financial Cryptography conference almost a year ago. Gabizon contacted Sean Bowe, a Zcash Company's cryptographer, immediately after discovering the counterfeiting vulnerability, as dubbed by the team, and the team decided to keep the flaw secret in order to avoid the risk o

Flaws in Popular RDP Clients Allow Malicious Servers to Reverse Hack PCs

February 05, 2019Swati Khandelwal
You've always been warned not to share remote access to your computer with any untrusted people for many reasons—it's basic cyber security advice, and common sense, right? But what if I say, you should not even trust anyone who invites or offers you full remote access to their computers? Security researchers at cybersecurity firm Check Point have discovered more than two dozen vulnerabilities in both open-source RDP clients and Microsoft's own proprietary client that could allow a malicious RDP server to compromise a client computer, reversely. RDP, or Remote Desktop Protocol, allows users to connect to remote computers. The protocol is usually used by technical users and IT administrators to remotely connect to other devices on the network. RDP was initially developed by Microsoft for its Windows operating system, but there are several open source clients for the RDP protocol that can be used on Linux as well as Unix systems. Check Point researchers recently
Severe RCE Flaw Disclosed in Popular LibreOffice and OpenOffice Software

Severe RCE Flaw Disclosed in Popular LibreOffice and OpenOffice Software

February 05, 2019Swati Khandelwal
It's 2019, and just opening an innocent looking office document file on your system can still allow hackers to compromise your computer. No, I'm not talking about yet another vulnerability in Microsoft Office, but in two other most popular alternatives— LibreOffice and Apache OpenOffice —free, open source office software used by millions of Windows, MacOS and Linux users. Security researcher Alex Inführ has discovered a severe remote code execution (RCE) vulnerability in these two open source office suites that could be triggered just by opening a maliciously-crafted ODT (OpenDocument Text) file. The attack relies on exploiting a directory traversal flaw, identified as CVE-2018-16858, to automatically execute a specific python library bundled within the software using a hidden onmouseover event. To exploit this vulnerability, Inführ created  an ODT file with a white-colored hyperlink (so it can't be seen) that has an "onmouseover" event to trick victim
Hacker who reported flaw in Hungarian Telekom faces up to 8-years in prison

Hacker who reported flaw in Hungarian Telekom faces up to 8-years in prison

February 01, 2019Mohit Kumar
Many of you might have this question in your mind: "Is it illegal to test a website for vulnerability without permission from the owner?" Or… "Is it illegal to disclose a vulnerability publicly?" Well, the answer is YES, it’s illegal most of the times and doing so could backfire even when you have good intentions. Last year, Hungarian police arrested a 20-year-old ethical hacker accused of finding and exploiting serious vulnerabilities in Magyar Telekom, the largest Hungarian telecommunication company, who is now facing up to 8 years in prison. According to local Hungarian media , the defender first discovered a severe vulnerability in Magyar Telekom systems in April 2018 and reported it to the company officials, who later invited him to a meeting. Reportedly, the hacker then traveled to Budapest for the meeting, which didn't go well as he expected, and apparently, the company did not permit him to test its systems further. However, the man conti
iCloud Possibly Suffered A Privacy Breach Last Year That Apple Kept a Secret

iCloud Possibly Suffered A Privacy Breach Last Year That Apple Kept a Secret

January 30, 2019Mohit Kumar
Late last year when an unknown group of hackers stole secret access tokens for millions of Facebook accounts by taking advantage of a flaw in its website, the company disclosed the incident and informed its affected users. Similarly, when Twitter was hit by multiple vulnerabilities ( #1 , #2 , #3 ) in the last few months, the social media company disclosed those incidents and informed its affected users. And Guess What? Google is going to shut down its social media network Google+ in April this year after admitting two security flaws in its platform that exposed private data of hundreds of thousands of users to third-party developers. It turns out that Apple also possibly suffered a privacy breach late last year due to a bug in its platform that might have exposed some of your iCloud data to other users, but the company chose to keep the incident secret... maybe because it was not worth to disclose, or perhaps much more complicated. Last week, Turkish security researcher Me
Millions of PCs Found Running Outdated Versions of Popular Software

Millions of PCs Found Running Outdated Versions of Popular Software

January 24, 2019Swati Khandelwal
It is 2019, and millions of computers still either have at least one outdated application installed or run outdated operating systems, making themselves vulnerable to online threats and known security vulnerabilities/exploits. Security vendor Avast has released its PC Trends Report 2019 revealing that millions of users are making themselves vulnerable to cyber attacks by keeping outdated versions of popular applications on their computers. Probably the most overlooked vectors for any cyber attack is out-of-date programs, which most of the times, is the result of the users’ laziness and company’s administrators ignoring the security updates in a business environment as they can't afford the downtime. According to the report [ PDF ],  Adobe Shockwave tops the list of software that most user left outdated on their PCs, followed by VLC Media Player, Skype, Java Runtime Environment , 7-Zip File Manager, and Foxit Reader. The outdated software applications often provide an ope

Chinese Hacker Publishes PoC for Remote iOS 12 Jailbreak On iPhone X

January 23, 2019Wang Wei
Here we have great news for all iPhone Jailbreak lovers and concerning one for the rest of iPhone users. A Chinese cybersecurity researcher has today revealed technical details of critical vulnerabilities in Apple Safari web browser and iOS that could allow a remote attacker to jailbreak and compromise victims' iPhoneX running iOS 12.1.2 and before versions. To do so, all an attacker needs to do is trick iPhoneX users into opening a specially crafted web page using Safari browser, that's it. However, finding flaws and creating a working exploit to carry out such attacks is not as easy as it may sound for every iOS hacker. Discovered by security researcher Qixun Zhao of Qihoo 360's Vulcan Team, the exploit takes advantage of two security vulnerabilities that were first demonstrated at TianfuCup hacking contest held in November last year and then was later responsibly reported to the Apple security team. Zhao today released some details of and a proof-of-concep
Critical RCE Flaw in Linux APT Allows Remote Attackers to Hack Systems

Critical RCE Flaw in Linux APT Allows Remote Attackers to Hack Systems

January 22, 2019Swati Khandelwal
Just in time… Some cybersecurity experts this week arguing over Twitter in favor of not using HTTPS and suggesting software developers to only rely on signature-based package verification, just because APT on Linux also does the same. Ironically, a security researcher just today revealed details of a new critical remote code execution flaw in the apt-get utility that can be exploited by a remote, man-in-the middle attacker to compromise Linux machines. The flaw, apparently, once again demonstrates that if the software download ecosystem uses HTTPS to communicate safely, such attacks can easily be mitigated at the first place. Discovered by Max Justicz, the vulnerability (CVE-2019-3462) resides in the APT package manager, a widely used utility that handles installation, update and removal of software on Debian, Ubuntu, and other Linux distributions. According to a blog post published by Justicz and details shared with The Hacker News, the APT utility doesn't properly

Flight Booking System Flaw Affected Customers of 141 Airlines Worldwide

January 16, 2019Swati Khandelwal
Almost half of the fight travelers around the world were found exposed to a critical security vulnerability discovered in online flight ticket booking system that allowed remote hackers to access and modify their travel details and even claim their frequent flyer miles. Israeli network security researcher Noam Rotem discovered the vulnerability when he booked a flight on the Israeli airline ELAL, successful exploitation of which just required victim's PNR (Passenger Name Record) number. The vulnerability resided in the widely used online flight booking system developed by Amadeus, which is currently being used by nearly 141 international airlines, including United Airlines, Lufthansa and Air Canada. After booking a flight with ELAL, the traveler receives a PNR number and a unique link that allows customers to check their booking status and related information associated with that PNR. Rotem found that merely by changing the value of the "RULE_SOURCE_1_ID" param

Fortnite Flaws Allowed Hackers to Takeover Gamers' Accounts

January 16, 2019Swati Khandelwal
Check Point researchers have discovered multiple security vulnerabilities in Fortnite, a massively popular online battle game, one of which could have allowed remote attackers to completely takeover player accounts just by tricking users into clicking an unsuspectable link. The reported Fortnite flaws include a SQL injection, cross-site scripting (XSS) bug, a web application firewall bypass issue, and most importantly an OAuth account takeover vulnerability. Full account takeover could be a nightmare, especially for players of such a hugely popular online game that has been played by 80 million users worldwide, and when a good Fortnite account has been sold on eBay for over $50,000. The Fortnite game lets its players log in to their accounts using third-party Single Sign-On (SSO) providers, such as Facebook, Google, Xbox, and PlayStation accounts. According to the researchers, the combination of cross-site scripting (XSS) flaw and a malicious redirect issue on the Epic Games&
