Recently uncovered two huge processor vulnerabilities called Meltdown and Spectre have taken the whole world by storm, while vendors are rushing out to patch the vulnerabilities in its products. The issues apply to all modern processors and affect nearly all operating systems (Windows, Linux, Android, iOS, macOS, FreeBSD, and more), smartphones and other computing devices made in the past 20 years. What are Spectre and Meltdown? We have explained both , Meltdown (CVE-2017-5754) and Spectre (CVE-2017-5753, CVE-2017-5715), exploitation techniques in our previous article. In short, Spectre and Meltdown are the names of security vulnerabilities found in many processors from Intel, ARM and AMD that could allow attackers to steal your passwords, encryption keys and other private information. Both attacks abuse 'speculative execution' to access privileged memory—including those allocated for the kernel—from a low privileged user process like a malicious app running on a...

Security researchers have unearthed multiple vulnerabilities in hundreds of GPS services that could enable attackers to expose a whole host of sensitive data on millions of online location tracking devices managed by vulnerable GPS services. The series of vulnerabilities discovered by two security researchers, Vangelis Stykas and Michael Gruhn, who dubbed the bugs as ' Trackmageddon ' in a report , detailing the key security issues they have encountered in many GPS tracking services. Trackmageddon affects several GPS services that harvest geolocation data of users from a range of smart GPS-enabled devices, including children trackers, car trackers, pet trackers among others, in an effort to enable their owners to keep track of where they are. According to the researchers, the vulnerabilities include easy-to-guess passwords (such as 123456), exposed folders, insecure API endpoints, and insecure direct object reference (IDOR) issues. By exploiting these flaws, an unaut...

Unlike the initial reports suggested about Intel chips being vulnerable to some severe 'memory leaking' flaws, full technical details about the vulnerabilities have now been emerged, which revealed that almost every modern processor since 1995 is vulnerable to the issues. Disclosed today by Google Project Zero , the vulnerabilities potentially impact all major CPUs, including those from AMD, ARM, and Intel—threatening almost all PCs, laptops, tablets, and smartphones, regardless of manufacturer or operating system. These hardware vulnerabilities have been categorized into two attacks , named Meltdown (CVE-2017-5754) and Spectre (CVE-2017-5753 and CVE-2017-5715), which could allow attackers to steal sensitive data which is currently processed on the computer. Both attacks take advantage of a feature in chips known as "speculative execution," a technique used by most modern CPUs to optimize performance. "In order to improve performance, many CPUs may choose t...

UPDATE: Researchers have finally disclosed complete technical details of two kernel side-channel attacks, Meltdown and Spectre — which affect not only Intel but also systems and devices running AMD, ARM processors —allowing attackers to steal sensitive data from the system memory. ____________ The first week of the new year has not yet been completed, and very soon a massive vulnerability is going to hit hundreds of millions of Windows, Linux, and Mac users worldwide. According to a blog post published yesterday, the core team of Linux kernel development has prepared a critical kernel update without releasing much information about the vulnerability. Multiple researchers on Twitter  confirmed that Intel processors (x86-64) have a severe hardware-level issue that could allow attackers to access protected kernel memory, which primarily includes information like passwords, login keys, and files cached from disk. The security patch implements kernel page-table isolation...

A critical security vulnerability has been reported in phpMyAdmin—one of the most popular applications for managing the MySQL database—which could allow remote attackers to perform dangerous database operations just by tricking administrators into clicking a link. Discovered by an Indian security researcher, Ashutosh Barot , the vulnerability is a cross-site request forgery (CSRF) attack and affects phpMyAdmin versions 4.7.x ( prior to 4.7.7 ). Cross-site request forgery vulnerability, also known as XSRF, is an attack wherein an attacker tricks an authenticated user into executing an unwanted action. According to an advisory released by phpMyAdmin, " by deceiving a user to click on a crafted URL, it is possible to perform harmful database operations such as deleting records, dropping/truncating tables, etc. " phpMyAdmin is a free and open source administration tool for MySQL and MariaDB and is widely used to manage the database for websites created with WordPress,...
