Google Introduces Enhanced Real-Time URL Protection for Chrome Users

Google Introduces Enhanced Real-Time URL Protection for Chrome Users

Mar 15, 2024 Browser Security / Phishing Attack
Google on Thursday announced an enhanced version of Safe Browsing to provide real-time, privacy-preserving URL protection and safeguard users from visiting potentially malicious sites. "The  Standard protection mode for Chrome  on desktop and iOS will check sites against Google's server-side list of known bad sites in real-time," Google's Jonathan Li and Jasika Bawa  said . "If we suspect a site poses a risk to you or your device, you'll see a warning with more information. By checking sites in real time, we expect to block 25% more phishing attempts." Up until now, the Chrome browser used a locally-stored list of known unsafe sites that's updated every 30 to 60 minutes, and then leveraging a  hash-based approach  to compare every site visited against the database. Google  first revealed  its plans to switch to real-time server-side checks without sharing users' browsing history with the company in September 2023. The reason for the change, the search giant said, is motivated b
Malware Campaign Exploits Popup Builder WordPress Plugin to Infect 3,900+ Sites

Malware Campaign Exploits Popup Builder WordPress Plugin to Infect 3,900+ Sites

Mar 12, 2024 WordPress / Website Security
A new malware campaign is leveraging a high-severity security flaw in the Popup Builder plugin for WordPress to inject malicious JavaScript code. According to Sucuri, the campaign has  infected more than 3,900 sites  over the past three weeks. "These attacks are orchestrated from domains less than a month old, with registrations dating back to February 12th, 2024," security researcher Puja Srivastava  said  in a report dated March 7. Infection sequences involve the exploitation of CVE-2023-6000, a security vulnerability in Popup Builder that could be exploited to create rogue admin users and install arbitrary plugins. The shortcoming was exploited as part of a  Balada Injector campaign  earlier this January, compromising no less than 7,000 sites. The latest set of attacks lead to the injection of malicious code, which comes in two different variants and is designed to redirect site visitors to other sites such as phishing and scam pages. WordPress site owners are reco
How to Find and Fix Risky Sharing in Google Drive

How to Find and Fix Risky Sharing in Google Drive

Mar 06, 2024Data Security / Cloud Security
Every Google Workspace administrator knows how quickly Google Drive becomes a messy sprawl of loosely shared confidential information. This isn't anyone's fault; it's inevitable as your productivity suite is purposefully designed to enable real-time collaboration – both internally and externally.  For Security & Risk Management teams, the untenable risk of any Google Drive footprint lies in the toxic combinations of sensitive data, excessive permissions, and improper sharing. However, it can be challenging to differentiate between typical business practices and potential risks without fully understanding the context and intent.  Material Security, a company renowned for its innovative method of protecting sensitive data within employee mailboxes, has recently launched  Data Protection for Google Drive  to safeguard the sprawl of confidential information scattered throughout Google Drive with a powerful discovery and remediation toolkit. How Material Security helps organ
QEMU Emulator Exploited as Tunneling Tool to Breach Company Network

QEMU Emulator Exploited as Tunneling Tool to Breach Company Network

Mar 08, 2024 Endpoint Security / Network Security
Threat actors have been observed leveraging the  QEMU  open-source hardware emulator as tunneling software during a cyber attack targeting an unnamed "large company" to connect to their infrastructure. While a number of legitimate tunneling tools like Chisel, FRP, ligolo, ngrok, and Plink have been used by adversaries to their advantage, the development marks the first QEMU that has been used for this purpose. "We found that QEMU supported connections between virtual machines: the -netdev option creates network devices (backend) that can then connect to the virtual machines," Kaspersky researchers Grigory Sablin, Alexander Rodchenko, and Kirill Magaskin  said . "Each of the numerous network devices is defined by its type and supports extra options." In other words, the idea is to create a virtual network interface and a socket-type network interface, thereby allowing the virtual machine to communicate with any remote server.

Exit Scam: BlackCat Ransomware Group Vanishes After $22 Million Payout

Exit Scam: BlackCat Ransomware Group Vanishes After $22 Million Payout

Mar 06, 2024 Cyber Crime / Ransomware
The threat actors behind the  BlackCat ransomware  have shut down their darknet website and likely pulled an exit scam after uploading a bogus law enforcement seizure banner. "ALPHV/BlackCat did not get seized. They are exit scamming their affiliates," security researcher Fabian Wosar  said . "It is blatantly obvious when you check the source code of the new takedown notice." "There is absolutely zero reason why law enforcement would just put a saved version of the takedown notice up during a seizure instead of the original takedown notice." The U.K.'s National Crime Agency (NCA)  told  Reuters that it had no connection to any disruptions to the BlackCat infrastructure. Recorded Future security researcher Dmitry Smilyanets  posted  screenshots on the social media platform X in which the BlackCat actors claimed that the "feds screwed us over" and that they intended to sell the ransomware's source code for $5 million.

TimbreStealer Malware Spreading via Tax-themed Phishing Scam Targets IT Users

TimbreStealer Malware Spreading via Tax-themed Phishing Scam Targets IT Users

Feb 28, 2024 Phishing Attack / Malware
Mexican users have been targeted with tax-themed phishing lures at least since November 2023 to distribute a previously undocumented Windows malware called  TimbreStealer . Cisco Talos, which  discovered  the activity, described the authors as skilled and that the "threat actor has previously used similar tactics, techniques and procedures (TTPs) to distribute a banking trojan known as  Mispadu  in September 2023. Besides employing sophisticated obfuscation techniques to sidestep detection and ensure persistence, the phishing campaign makes use of geofencing to single out users in Mexico, returning an innocuous blank PDF file instead of the malicious one if the payload sites are contacted from other locations. Some of the notable evasive maneuvers include leveraging custom loaders and direct system calls to bypass conventional API monitoring, in addition to utilizing Heaven's Gate to execute 64-bit code within a 32-bit process, an approach that was also recently adopted by
