Zoom’s Zero-Day Flaw Exposed: How Hackers Exploit Vanity URLs
Zoom’s Vanity URL Feature: A Hacker’s Playground
Zoom’s Vanity URL feature, which lets organizations craft custom URLs like https://<organization_name>.zoom.us, has recently been found to harbor a critical zero-day vulnerability. This flaw, uncovered by CheckPoint researchers, allows attackers to pose as organization insiders and pilfer sensitive data.
The Exploit: A Wolf in Sheep’s Clothing
By snagging a custom URL with a target organization’s name, hackers can send out meeting invites, luring victims into their trap. They use social engineering tactics to trick victims into joining meetings, where they can then swipe sensitive info from unsuspecting participants.
CheckPoint researchers found that attackers could send a meeting link in the format https://<organization_name>.zoom.us/j/##########, instead of the usual https://zoom.us/j/##########, to dupe victims into joining bogus meetings.
Zoom’s Countermove
Zoom has since patched up the vulnerability reported by CheckPoint. They’re now advising users to scrutinize meeting details before joining and to only join meetings from trusted sources.
RustScan: Nmap’s New Sidekick
Nmap, a popular open-source security scanner, just got a speed boost thanks to RustScan, a tool cooked up by Brandon Skerritt. RustScan revs up Nmap’s operations by sniffing out open ports on target systems and handing off these results to Nmap.
RustScan’s Superpowers
RustScan can scan all 65,535 ports in a mere 8-10 seconds, making Nmap’s scans a whole lot faster. By quickly spotting open ports, RustScan kicks off Nmap scans more efficiently, slashing the time needed for thorough scans. For instance, a scan that takes 17 minutes with Nmap can be wrapped up in just 39 seconds with RustScan.
For installation instructions, hit up the RustScan GitHub page. To install on Debian/KALI, grab the Debian package file and use the dpkg -i command.
Docker API: A New Battleground for Cyber Attacks
In July 2020, cybersecurity sleuths stumbled upon a new type of attack involving Docker images. Hackers are exploiting misconfigured Docker APIs to launch cyber assaults in cloud-native environments, aiming to dig in their heels and persist in systems.
The Attack: A Trojan Horse
Instead of pulling from a public registry, attackers craft malicious images using misconfigured Docker API ports. They can download harmful elements like XMRIG from remote sources during the machine creation process, bypassing browser-based security systems. The fleeting nature of these images makes them tough to remove and block, as their names and IDs are randomly generated.
ProcMon for Linux: Microsoft’s Gift to SysAdmins
ProcMon (Process Monitor) is a powerful monitoring tool for Windows that displays real-time file system, registry, and process/thread activities. Microsoft has just dropped a Linux version of ProcMon.
ProcMon for Linux: Features and Installation
ProcMon for Linux lets users keep an eye on system events in real-time and filter them based on various criteria like directories, users, processes, and duration. It also logs events in detail, aiding in troubleshooting and malware detection.
To install ProcMon-for-Linux on Ubuntu 18.04 and above, follow these steps:
- Download the package:
wget -q -O packages-microsoft-prod.deb https://packages.microsoft.com/config/ubuntu/18.04/packages-microsoft-prod.deb - Install the package:
sudo dpkg -i packages-microsoft-prod.deb - Update and install ProcMon:
sudo apt-get updateandsudo apt-get install procmon
