Two Critical Flaws in Zoom Could've Let Attackers Hack Systems via Chat

June 03, 2020Mohit Kumar
If you're using Zoom —especially during this challenging time to cope with your schooling, business, or social engagement—make sure you are running the latest version of the widely popular video conferencing software on your Windows, macOS, or Linux computers. No, it's not about the arrival of the most-awaited "real" end-to-end encryption feature, which apparently, according to the latest news, would now only be available to paid users . Instead, this latest warning is about two newly discovered critical vulnerabilities. Cybersecurity researchers from Cisco Talos unveiled today that it discovered two critical vulnerabilities in the Zoom software that could have allowed attackers to hack into the systems of group chat participants or an individual recipient remotely. Both flaws in question are path traversal vulnerabilities that can be exploited to write or plant arbitrary files on the systems running vulnerable versions of the video conferencing software to e

A new set of critical vulnerabilities uncovered in SAP's Sybase database software can grant unprivileged attackers complete control over a targeted database and even the underlying operating system in certain scenarios. The six flaws, disclosed by cybersecurity firm Trustwave today, reside in Sybase Adaptive Server Enterprise ( ASE ), a relational database management software geared towards transaction-based applications. The cybersecurity company said the issues — both specific to the operating system and the platform as a whole — were discovered during a security testing of the product, one of which has a CVSS rating of 9.1. Identified as CVE-2020-6248 , the most severe vulnerability allows arbitrary code execution when making database backups, thus allowing an attacker to trigger the execution of malicious commands. "During database backup operations, there are no security checks for overwriting critical configuration files," Trustwave researchers said  in a

New Skill Testing Platform For 6 Most In-Demand Cybersecurity Jobs

June 03, 2020The Hacker News
Building a security team is a necessity for organizations of all industries and sizes. It makes selecting the right person for the job a critical task in which testing candidates' domain knowledge is a core component of the hiring process. A common practice is for each organization to put together a dedicated set of questions for each role. Today, Cynet launches the Cybersecurity Skill Tests website to optimize the hiring process with an automated online questionnaire form for each such position. Cynet has assembled a vast question pool with hundreds of dedicated questions for the 6 leading cybersecurity positions (see below), covering all aspects of each selected role. A selection algorithm is used to generate a set of 25 questions in increasing difficulty level, which touches all the important knowledge areas of each candidate's position. No two questionnaires are the same to ensure the answers' reliability. How does this work in practice? Following the

How to Create a Culture of Kick-Ass DevSecOps Engineers

Much like technology itself, the tools, techniques, and optimum processes for developing code evolve quickly. We humans have an insatiable need for more software, more features, more functionality… and we want it faster than ever before, more qualitative, and on top of that: Secure. With an estimated 68% of organizations experiencing zero-day attacks from undisclosed/unknown vulnerabilities in 2019, this is an upward trend that we need to address as an industry by shipping secure code at a reasonable speed. While many people and organizations are moving on from Waterfall to Agile — and not everybody is there yet, let's be real — they are already encountering a new problem. Development teams and their operations counterparts are still working in silos, and this is still causing headaches for development managers and their counterparts across the business. In this environment, how can small teams working in an Agile way deliver on that promise of faster deployment, and fast
Joomla Resources Directory (JRD) Portal Suffers Data Breach

Joomla Resources Directory (JRD) Portal Suffers Data Breach

June 01, 2020Ravie Lakshmanan
Joomla, one of the most popular Open-source content management systems (CMS), last week announced a new data breach impacting 2,700 users who have an account with its resources directory (JRD) website, i.e., resources.joomla.org. The breach exposed affected users' personal information, such as full names, business addresses, email addresses, phone numbers, and encrypted passwords. The company said the incident came to light during an internal website audit that revealed that a member of the Joomla Resources Directory (JRD) team stored a full unencrypted backup of the JRD website on an Amazon Web Services S3 bucket owned by the third-party company. The affected JRD portal lists developers and service providers specialized in Joomla, allowing registered users to extend their CMS with additional functionalities. Joomla said the investigation is still ongoing and that accesses to the website have been temporarily suspended. It has also reached out to the concerned third-pa

Apple recently paid Indian vulnerability researcher Bhavuk Jain a huge $100,000 bug bounty for reporting a highly critical vulnerability affecting its ' Sign in with Apple ' system. The now-patched vulnerability could have allowed remote attackers to bypass authentication and take over targeted users' accounts on third-party services and apps that have been registered using 'Sign in with Apple' option. Launched last year at Apple's WWDC conference, ' Sign in with Apple ' feature was introduced to the world as a privacy-preserving login mechanism that allows users to sign up an account with 3rd-party apps without disclosing their actual email addresses (also used as Apple IDs). In an interview with The Hacker News, Bhavuk Jain revealed that the vulnerability he discovered resided in the way Apple was validating a user on the client-side before initiating a request from Apple's authentication servers. For those unaware, while authenticating
 New Noise-Resilient Attack On Intel and AMD CPUs Makes Flush-based Attacks Effective

New Noise-Resilient Attack On Intel and AMD CPUs Makes Flush-based Attacks Effective

May 30, 2020Ravie Lakshmanan
Modern Intel and AMD processors are susceptible to a new form of side-channel attack that makes flush-based cache attacks resilient to system noise, newly published research shared with The Hacker News has revealed. The findings are from a paper " DABANGG: Time for Fearless Flush based Cache Attacks " published by a pair of researchers, Biswabandan Panda and Anish Saxena, from the Indian Institute of Technology (IIT) Kanpur earlier this week. Dubbed " Dabangg " (meaning fearless), the approach builds upon the Flush+Reload and Flush+Flush attacks, which have been exploited previously by other researchers to leak data from Intel CPUs. However, the new variant aims to improve the accuracy of these attacks even in a noisy multi-core system. It also works seamlessly against non-Linux Operating Systems, like macOS. "Like any other cache attacks, flush based cache attacks rely on the calibration of cache latency," Biswabandan Panda, assistant profes
