AppTrana — Website Security Solution That Actually Works

July 02, 2019The Hacker News
Data loss and theft continues to rise, and hardly a day goes by without significant data breaches hit the headlines. In January 2019 alone, 1.76 billion records were leaked, and according to IBM's Data Breach study, the average cost of each lost or stolen record has reached about $148. Most of these data leaks are because of malicious attacks, where exploitation of web application vulnerabilities is one of the most common cyber attack vectors. An application security breach is a problem facing one and all, and no matter what's the size of your company, your web applications are prone to cyber attacks. Hackers breach sites for a variety of reasons—some do it for fame, some to get competitive information, whereas some do it just for financial gains. No matter what the reason is, the cost of a security breach is always higher than the cost of protection, leading to loss of data, substantial financial losses, and most importantly, loss of customers' trust. If you a

Critical Flaw Reported in Popular Evernote Extension for Chrome Users

June 13, 2019Swati Khandelwal
Cybersecurity researchers discover a critical flaw in the popular Evernote Chrome extension that could have allowed hackers to hijack your browser and steal sensitive information from any website you accessed. Evernote is a popular service that helps people taking notes and organize their to-do task lists, and over 4,610,000 users have been using its Evernote Web Clipper Extension for Chrome browser. Discovered by Guardio, the vulnerability ( CVE-2019-12592 ) resided in the ways Evernote Web Clipper extension interacts with websites, iframes and inject scripts, eventually breaking the browser's same-origin policy (SOP) and domain-isolation mechanisms. According to researchers, the vulnerability could allow an attacker-controlled website to execute arbitrary code on the browser in the context of other domains on behalf of users, leading to a Universal Cross-site Scripting (UXSS or Universal XSS) issue. "A full exploit that would allow loading a remote hacker contr

Severe Flaw Disclosed In StackStorm DevOps Automation Software

Severe Flaw Disclosed In StackStorm DevOps Automation Software

March 11, 2019Mohit Kumar
A security researcher has discovered a severe vulnerability in the popular, open source event-driven platform StackStorm that could allow remote attackers to trick developers into unknowingly execute arbitrary commands on targeted services. StackStorm, aka "IFTTT for Ops," is a powerful event-driven automation tool for integration and automation across services and tools that allows developers to configure actions, workflows, and scheduled tasks, in order to perform some operations on large-scale servers. For example, you can set instructions (if this, then that) on Stackstorm platform to automatically upload network packet files to a cloud-based network analyze service, like CloudShark, in events when your security software detects an intrusion or malicious activity in the network. Since StackStorm executes actions—which can be anything, from the HTTP request to an arbitrary command—on remote servers or services that developers integrate for automated tasks, the pl

New Apache Struts Zero-Day Vulnerability Being Exploited in the Wild

March 09, 2017Swati Khandelwal
Security researchers have discovered a Zero-Day vulnerability in the popular Apache Struts web application framework, which is being actively exploited in the wild. Apache Struts is a free, open-source, Model-View-Controller (MVC) framework for creating elegant, modern Java web applications, which supports REST, AJAX, and JSON. In a blog post published Monday, Cisco's Threat intelligence firm Talos announced the team observed a number of active attacks against the zero-day vulnerability (CVE-2017-5638) in Apache Struts. According to the researchers, the issue is a remote code execution vulnerability in the Jakarta Multipart parser of Apache Struts that could allow an attacker to execute malicious commands on the server when uploading files based on the parser.

Yahoo Hacked Once Again! Quietly Warns Affected Users About New Attack

February 16, 2017Mohit Kumar
Has Yahoo rebuilt your trust again? If yes, then you need to think once again, as the company is warning its users of another hack. Last year, Yahoo admitted two of the largest data breaches on record. One of which that took place in 2013 disclosed personal details associated with more than 1 Billion Yahoo user accounts . Well, it's happened yet again. Yahoo sent out another round of notifications to its users on Wednesday, warning that their accounts may have been compromised as recently as last year after an ongoing investigation turned up evidence that hackers used forged cookies to log accounts without passwords. The company quietly revealed the data breach in security update in December 2016, but the news was largely overlooked, as the statement from Yahoo provided information on a separate data breach that occurred in August 2013 involving more than 1 billion accounts. The warning message sent Wednesday to some Yahoo users read: "Based on the ongoing i

Update — Hacker Claims to Have Hacked the FBI, But It Wasn't

January 05, 2017Mohit Kumar
Update: A hacker yesterday claimed to have hacked the FBI's website running on Plone CMS, but it seems it wasn't hacked using any zero-day vulnerability in Plone. We contacted Plone security team and updated this story (see below) with official statements. A hacker, using Twitter handle CyberZeist , has claimed to have hacked the FBI's website (fbi.gov) and leaked personal account information of several FBI agents publically. CyberZeist had initially exposed the flaw on 22 December, giving the FBI time to patch the vulnerability in its website's code before making the data public. The hacker exploited a zero-day vulnerability in the Plone CMS , an Open Source Content Management software used by FBI to host its website, and leaked personal data of 155 FBI officials to Pastebin , including their names, passwords, and email accounts. CyberZeist tweeted multiple screenshots as proof of his claims, showing his unauthorized access to server and database files usi
Someone Hijacking Unsecured MongoDB Databases for Ransom

Someone Hijacking Unsecured MongoDB Databases for Ransom

January 04, 2017Swati Khandelwal
Nearly two years back, we warned users about publicly accessible MongoDB instances – almost 600 Terabytes (TB) – over the Internet which require no authentication, potentially leaving websites and servers at risk of hacking. These MongoDB instances weren't exposed due to any flaw in its software, but due to a misconfiguration (bad security practice) that let any remote attacker access MongoDB databases without using any special hacking tool. MongoDB later resolved the issue in the next version of its software by setting unrestricted remote access by default in the configuration, thousands of site administrators have not updated their servers yet. But trust me, they'll now regret this! A Hacker is now hijacking and wiping out unsecured MongoDB databases , but keeping a copy of those databases for asking administrators a ransom of 0.2 Bitcoins (nearly US$211) to return the lost data. So, admins without backups are left in a bind. In fact, the rising price of Bitcoin

3 Critical Zero-Day Flaws Found in PHP 7 — One Remains Unpatched!

December 29, 2016Swati Khandelwal
Three critical zero-day vulnerabilities have been discovered in PHP 7 that could allow an attacker to take complete control over 80 percent of websites which run on the latest version of the popular web programming language. The critical vulnerabilities reside in the unserialized mechanism in PHP 7 – the same mechanism that was found to be vulnerable in PHP 5 as well, allowing hackers to compromise Drupal, Joomla, Magento, vBulletin and PornHub websites and other web servers in the past years by sending maliciously crafted data in client cookies. Security researchers at Check Point's exploit research team spent several months examining the unserialized mechanism in PHP 7 and discovered "three fresh and previously unknown vulnerabilities" in the mechanism. While researchers discovered flaws in the same mechanism, the vulnerabilities in PHP 7 are different from what was found in PHP 5. Tracked as CVE-2016-7479, CVE-2016-7480, and CVE-2016-7478, the zero-day flaw

Sometimes I receive emails from our readers who wanted to know how to hack Facebook account , but just to delete some of their messages they have sent to their friends or colleagues mistakenly or under wrong circumstances like aggression. How to hack a Facebook account? It is probably the biggest "n00b" question you will see on the Internet. The solution for this query is hard to find — but recently researchers have shown that how you can modify or alter your messages once you have pressed the SEND button in Facebook Messenger. According to the researcher  Roman Zaikin  from cyber security firm Check Point , a simple HTML tweak can be used to exploit Facebook online chat as well as its Messenger app, potentially allowing anyone to modify or delete any of his/her sent message, photo, file, and link. Though the bug is simple, it could be exploited by malicious users to send a legitimate link in a Facebook chat or group chat, and later change it to a malicious link t
