There are over a hundred potential ways hackers can ruin your life by having access to your WiFi network that's also connected to your computers, smartphones, and other smart devices. Whether it's about exploiting operating system and software vulnerabilities or manipulating network traffic, every attack relies on the reachability between an attacker and the targeted devices. In recent years, we have seen how hundreds of widely used smart-but-insecure devices made it easier for remote attackers to sneak into connected networks without breaking WiFi passwords. In the latest research shared with The Hacker News, Check Point experts today revealed a new high-severity vulnerability affecting Philips Hue Smart Light Bulbs that can be exploited over-the-air from over 100 meters away to gain entry into a targeted WiFi network. The underlying high-severity vulnerability, tracked as CVE-2020-6007 , resides in the way Philips implemented the Zigbee communication protocol in it...

A cybersecurity researcher today disclosed technical details of multiple high severity vulnerabilities he discovered in WhatsApp, which, if exploited, could have allowed remote attackers to compromise the security of billions of users in different ways. When combined together, the reported issues could have even enabled hackers to remotely steal files from the Windows or Mac computer of a victim using the WhatsApp desktop app by merely sending a specially crafted message. Discovered by PerimeterX researcher Gal Weizman and tracked as CVE-2019-18426 , the flaws specifically resided in WhatsApp Web, a browser version of the world's most popular messaging application that also powers its Electron-based cross-platform apps for desktop operating systems. In a blog post published today, Weizman revealed that WhatsApp Web was vulnerable to a potentially dangerous open-redirect flaw that led to persistent cross-site scripting attacks, which could have been triggered by sending a s...

Google might have mistakenly shared your private videos saved on the company's servers with other users, the tech giant admitted yesterday in a security notification sent quietly to an undisclosed number of affected users. The latest privacy mishap is the result of a "technical issue" in Google's Takeout , a service that backs up all your Google account data into a single file and then lets you download it straight away. According to a screenshot Jon Oberheide of Duo Security shared on Twitter, the issue reportedly remained active between 21st November and 25th November last year, during which "some videos in Google Photos [service] were incorrectly exported to unrelated user's archives." Vice versa, if you had also requested for your account backup during the same 5-day period, you might have even received unrelated videos from other Google accounts. So, the data leak incident potentially affects only those who used Google Takeout service...

Twitter today issued a warning revealing that attackers abused a legitimate functionality on its platform to unauthorizedly determine phone numbers associated with millions of its users' accounts. According to Twitter, the vulnerability resided in one of the APIs that has been designed to make it easier for users to find people they may already know on Twitter by matching phone numbers saved in their contacts with twitter accounts. To be noted, the feature worked precisely as intended, except someone was not supposed to upload millions of randomly generated phone numbers and abuse Twitter to reveal profiles associated with the contact information users added to Twitter for enabling security features. Though the company is not sure if the bug was exploited by only a single adversary or multiple groups, it has identified several accounts engaged in the attack located in a wide range of countries, primarily from Iran, Israel, and Malaysia. Based on their IP addresses, Twitt...

Joe Vennix of Apple security has found another significant vulnerability in sudo utility that under a specific configuration could allow low privileged users or malicious programs to execute arbitrary commands with administrative ('root') privileges on Linux or macOS systems. Sudo is one of the most important, powerful, and commonly used utilities that comes as a core command pre-installed on macOS and almost every UNIX or Linux-based operating system. Sudo has been designed to let users run apps or commands with the privileges of a different user without switching environments. Sudo Vulnerability (CVE-2019-18634) The newly discovered privilege escalation vulnerability, tracked as CVE-2019-18634 , in question stems from a stack-based buffer overflow issue that resides in Sudo versions before 1.8.26. According to Vennix, the flaw can only be exploited when the " pwfeedback " option is enabled in the sudoers configuration file, a feature that provides visua...
