New Banking Trojan CHAVECLOAK Targets Brazilian Users via Phishing Tactics

New Banking Trojan CHAVECLOAK Targets Brazilian Users via Phishing Tactics

Mar 11, 2024 Phishing Attack / Mobile Security
Users in Brazil are the target of a new banking trojan known as  CHAVECLOAK  that's propagated via phishing emails bearing PDF attachments. "This intricate attack involves the PDF downloading a ZIP file and subsequently utilizing DLL side-loading techniques to execute the final malware," Fortinet FortiGuard Labs researcher Cara Lin  said . The attack chain involves the use of contract-themed DocuSign lures to trick users into opening PDF files containing a button to read and sign the documents. In reality, clicking the button leads to the retrieval of an installer file from a remote link that's shortened using the Goo.su URL shortening service. Present within the installer is an executable named "Lightshot.exe" that leverages DLL side-loading to load "Lightshot.dll," which is the CHAVECLOAK malware that facilitates the theft of sensitive information. This includes gathering system metadata and running checks to determine whether the compromis

This Android File Manager App Infected Thousands of Devices with SharkBot Malware

Nov 24, 2022
The Android banking fraud malware known as SharkBot has reared its head once again on the official Google Play Store, posing as file managers to bypass the app marketplace's restrictions. A majority of the users who downloaded the rogue apps are located in the U.K. and Italy, Romanian cybersecurity company Bitdefender  said  in an analysis published this week. SharkBot, first  discovered  towards the end of 2021 by Cleafy, is a  recurring   mobile   threat  distributed both on the Google Play Store and other third-party app stores. One of the trojan's primary goals is to initiate money transfers from compromised devices via a technique called "Automatic Transfer System" ( ATS ), in which a transaction triggered via a banking app is intercepted to swap the payee account with an actor-controlled account in the background. It's also capable of serving a fake login overlay when users attempt to open legitimate banking apps, stealing the credentials in the proce

Timing is Everything: The Role of Just-in-Time Privileged Access in Security Evolution

Apr 15, 2024Active Directory / Attack Surface
To minimize the risk of privilege misuse, a trend in the privileged access management (PAM) solution market involves implementing just-in-time (JIT) privileged access. This approach to  privileged identity management  aims to mitigate the risks associated with prolonged high-level access by granting privileges temporarily and only when necessary, rather than providing users with continuous high-level privileges. By adopting this strategy, organizations can enhance security, minimize the window of opportunity for potential attackers and ensure that users access privileged resources only when necessary.  What is JIT and why is it important?   JIT privileged access provisioning  involves granting privileged access to users on a temporary basis, aligning with the concept of least privilege. This principle provides users with only the minimum level of access required to perform their tasks, and only for the amount of time required to do so. One of the key advantages of JIT provisioning
