A newly discovered glitch in Zoom's screen sharing feature can accidentally leak sensitive information to other attendees in a call, according to the latest findings. Tracked as  CVE-2021-28133 , the unpatched security vulnerability makes it possible to reveal contents of applications that are not shared, but only briefly, thereby making it harder to exploit it in the wild. It's worth pointing out that the  screen sharing  functionality in Zoom lets users share an entire desktop or phone screen, or limit sharing to one or more specific applications, or a portion of a screen. The issue stems from the fact that a second application that's overlayed on top of an already shared application can reveal its contents for a short period of time. "When a Zoom user shares a specific application window via the 'share screen' functionality, other meeting participants can briefly see contents of other application windows which were not explicitly shared," SySS rese...

A pair of critical vulnerabilities in a popular bulletin board software called MyBB could have been chained together to achieve remote code execution (RCE) without the need for prior access to a privileged account. The flaws, which were discovered by independent security researchers Simon Scannell and Carl Smith, were reported to the MyBB Team on February 22, following which it  released  an update (version 1.8.26) on March 10 addressing the issues. MyBB, formerly MyBBoard and originally MyBulletinBoard, is free and open-source forum software developed using PHP and MySQL. According to internet assets search engine Spyse, there are at least 2,100 potentially vulnerable domains that have MyBB installed. According to the researchers, the first issue — a nested auto URL persistent XSS vulnerability (CVE-2021-27889) — stems from how MyBB parses messages containing URLs during the rendering process, thus enabling any unprivileged forum user to embed stored XSS payloads into t...

Are you looking to becoming a malware analyst? Then continue reading to discover how to gain the training you need and start a career in malware analysis career. Did you know that new malware is released every seven seconds? As more and more systems become reliant on the internet, the proliferation of malware becomes increasingly destructive. Once upon a time, a computer virus might cause considerable inconvenience, but its reach might have been limited to the handful of systems connected to the internet. Today, with every home, factory, and institution online, it's theoretically possible for malware to shut down an entire nation. That's where malware analysis comes in. Malware analysis is the process of isolating and reverse-engineering malicious software. Malware analysts draw on a wide range of skills, from programming to digital forensics, to identify and understand different types of malware. From there, they can design security solutions to protect computers from sim...

When a user account becomes locked out, the cause is often attributed to a user who has simply entered an old or incorrect password too many times. However, this is far from being the only thing that can cause an account to become locked. Another common cause, for example, is an application or script that is configured to log into the system using an old password. Perhaps the most easily overlooked cause of account lockouts, however, is the use of cached credentials. Before I explain  why cached credentials can be problematic , let's first consider what the Windows cached credentials do and why they are necessary. Cached and stored credentials Cached credentials are a mechanism that is used to ensure that users have a way of logging into their device in the event that the device is unable to access the Active Directory. Suppose for a moment that a user is working from a domain-joined laptop and is connected to the corporate network. In that type of situation, the Active Direc...

Privacy-focused search engine DuckDuckGo called out rival Google for "spying" on users after the search giant updated its flagship app to spell out the exact kinds of information it collects for personalization and marketing purposes. "After months of stalling, Google finally revealed how much personal data they collect in Chrome and the Google app. No wonder they wanted to hide it," the company  said  in a tweet. "Spying on users has nothing to do with building a great web browser or search engine." The " privacy nutrition labels " are part of a new policy that  went into effect  on December 8, 2020, mandating app developers to disclose their data collection practices and help users understand how their personal information is put to use. The insinuation from DuckDuckGo comes as Google has been steadily adding app privacy labels to its iOS apps over the course of the last several weeks in accordance with Apple's App Store rules, but not ...

Researchers have disclosed vulnerabilities in multiple WordPress plugins that, if successfully exploited, could allow an attacker to run arbitrary code and take over a website in certain scenarios. The flaws were uncovered in  Elementor , a website builder plugin used on more than seven million sites, and  WP Super Cache , a tool used to serve cached pages of a WordPress site. According to Wordfence, which discovered the security weaknesses in Elementor, the bug concerns a set of  stored cross-site scripting  (XSS) vulnerabilities (CVSS score: 6.4), which occurs when a malicious script is injected directly into a vulnerable web application. In this case, due to a lack of validation of the HTML tags on the server-side, a bad actor can exploit the issues to add executable JavaScript to a post or page via a crafted request. "Since posts created by contributors are typically reviewed by editors or administrators before publishing, any JavaScript added to one of the...

Email security firm Mimecast on Tuesday revealed that the state-sponsored SolarWinds hackers who broke into its internal network also downloaded source code out of a limited number of repositories. "The threat actor did access a subset of email addresses and other contact information and hashed and salted credentials," the company  said  in a write-up detailing its investigation, adding the adversary "accessed and downloaded a limited number of our source code repositories, as the threat actor is reported to have done with other victims of the SolarWinds Orion supply chain attack." But Mimecast said the source code downloaded by the attackers was incomplete and would be insufficient to build and run any aspect of the Mimecast service and that it did not find signs of any tampering made by the threat actor to the build process associated with the executables that are distributed to its customers.  On January 12, Mimecast  disclosed  that "a sophisticated th...

It's not every day that one of the best-known independent cybersecurity individuals joins a cybersecurity company. The two are generally on opposite sides of the coin, with little crossover. After all, they're usually concerned with different parts of the cybersecurity puzzle – one providing platforms and tools to defend organizations, the other keeping them accountable and looking for blind spots in even the best security tools. That seems to be changing, however, with a recent appointment. Cynet, an Autonomous XDR provider that recently closed a Series C funding round worth $40 million, announced that it has hired Chris Roberts as their Chief Security Strategist. Roberts is world-renowned in counter-threat intelligence, as well as in vulnerability and threat research fields, thanks to decades of experience. As part of his efforts at Cynet, Roberts will be focusing his work on helping empower and connect security professionals from organizations outside of the Fortune 200...

A Florida teen accused of masterminding the hacks of several high-profile Twitter accounts last summer as part of a widespread cryptocurrency scam pled guilty to fraud charges in exchange for a three-year prison sentence. Graham Ivan Clark, 18, will also serve an additional three years on probation. The development comes after the U.S. Department of Justice (DoJ)  charged  Mason Sheppard (aka Chaewon), Nima Fazeli (aka Rolex), and Clark (then a juvenile) with conspiracy to commit wire fraud and money laundering. Specifically, 30 felony charges were filed against Clark, including one count of organized fraud, 17 counts of communications fraud, one count of fraudulent use of personal information with over $100,000 or 30 or more victims, 10 counts of fraudulent use of personal information, and one count of access to computer or electronic device without authority. On July 15, 2020, Twitter  suffered  one of the biggest security lapses in its history after the atta...
