/in


Welcome to our comprehensive guide on choosing the perfect internet security suite for Windows 11! In an increasingly digital world, protecting your computer and personal information has become more crucial than ever. As hackers and cyber threats continue to evolve, it’s essential to equip yourself with a robust defense system that safeguards against viruses, malware, phishing attacks, and more. In this blog post, we will walk you through the crucial aspects to consider when selecting an internet security suite tailored specifically for Windows 11. So let’s dive in and fortify your online presence like never before!

Introduction to Internet Security and Windows 11

With the increasing use of the internet for various purposes such as communication, entertainment, banking, and shopping, it has become more important than ever to ensure the security of our devices and personal information. Windows 11, the latest operating system from Microsoft, comes with enhanced security features to protect its users from cyber threats. However, relying solely on these built-in features may not be enough. This is where internet security suites come into play.

In this section, we will discuss the basics of internet security and how it relates to Windows 11. We will also explore some of the key factors to consider when choosing an internet security suite for your device running on Windows 11.

Understanding Internet Security

Internet security refers to the measures taken to protect computers or networks from unauthorized access and attacks that can compromise or steal sensitive information. This includes protecting against viruses, malware, spyware, phishing scams, and other types of cyber threats.

Windows 11 offers built-in features such as a firewall, anti-malware protection through Microsoft Defender Antivirus (formerly known as Windows Defender), and secure boot technology to safeguard against external attacks. However, these features may not be enough to provide…

MSRT, la herramienta poco conocida de Windows para detectar malware

Aunque Windows tiene en Windows Defender el principal programa de seguridad del sistema operativo, existe una función menos conocida que ofrece funciones importantes de producción y vale la pena verificar, se trata de la Microsoft Software Removal Tool, o MSRT.

Esta herramienta se encuentra oculta en las profundidades del sistema operativo. MSRT no es programa en tiempo real como Windows Defender, pero es función que trabaja desde lo más profundo y a continuación vamos a explicar de qué se trata y cómo usarla.

Microsoft Software Removal Tool es una herramienta de seguridad que está incorporada en los sistemas operativos actuales de Microsoft, Windows 10 y 11. Su función principal es detectar y eliminar malware conocido y frecuente que puede haberse infiltrado en el sistema.

Aunque no sustituye la necesidad de un software antivirus completo, MSRT es una función valiosa para llevar a cabo análisis y limpiezas puntuales. A diferencia de Windows Defender, que trabaja silenciosamente en segundo plano, MSRT espera instrucciones del usuario para entrar en acción.

Esta herramienta debe ser activada por cada uno y para eso hay que seguir una serie de pasos:

1. Presionar las teclas Windows + R en el teclado. Esto abrirá la ventana Ejecutar de Windows.

2. En esta ventana escribir “mrt” (sin comillas) y presionar la tecla Enter o hacer clic en Aceptar.

3. Una vez que se haya ejecutado el comando, se abrirá la ventana de la Microsoft Software Removal Tool.

Una vez hayamos llegado a esta ventana aparecerán tres opciones de seguridad:

– Análisis Rápido: esta opción escanea áreas del sistema que son propensas a contener software malicioso. Es una excelente elección si se necesita una evaluación rápida de tu sistema.

– Análisis Completo: sirve para una revisión exhaustiva de todo el sistema en busca de amenazas. Esta opción examina cada rincón del PC en busca de malware.

– Análisis Personalizado: esta opción permite personalizar la ubicación o carpeta que se desea escanear….

Serious Security: Hacking Windows passwords via your wallpaper

Our cybersecurity antennae always start vibrating when we see warnings about attacks that involve a new type of file.
We’re sure you have the same sort of reaction.
After all, if a file type that you’ve treated for years as mostly harmless suddenly turns out to be possibly very dangerous, you’re faced with a double dilemma:
We’re all aware of the risks posed by unknown EXE files, for example, because EXE is the extension for native Windows programs – even the operating system itself is implemented as a collection of EXEs.
Most of us also know to be wary of DLLs, which are actually just a special type of EXE file with a different extension to denote that they’re usually used in combination with other programs, rather than loaded on their own.
We’ve learned to be wary of DOCs and DOCXs and all the other Office filetypes, too, because they can include embedded programs called macros.
We’re also aware of a range of risky script files such as JS (for JavaScript), VBS (Visual Basic Script), PS1 (Powershell) and many others that are plain old text files to the untrained eye, but are treated as a series of system commands when processed by Windows itself.
We’ve even taught ourelves to be wary of the extent to which Windows itself misleads us because of its default approach to filenames – as in the case of the files alert and alert.txt below, which go out of their way to convince us they’re just innocent text:
wp file only 640 1
Forget what they look like: those old-school icons on the left that give the impression of being medieval scrolls don’t denote plain old written text at all.
Ironically, however, the icon in the middle that looks like a crisply modern digital document, and that goes with a file that’s actually called document, really is a text file.
By default, Windows suppresses filename extensions, which are the all-important characters that follow the last dot in a filename, such as the .docx at the end of the Word file TaxReturn.docx or the .exe at the end of the program Notepad.exe.
Annoyingly, Windows itself very often uses extensions to decide what to do when you click on a file – for example, whether to view it harmlessly or to execute it…

ZenRAT Malware Targets Windows Users Via Fake Bitwarden Password Manager Installation Package

/in


Windows operating systems are the target of new malware dubbed ZenRAT by U.S.-based cybersecurity company Proofpoint. The attackers built a website that impersonates the popular Bitwarden password manager; if accessed via Windows, the fake site delivers the ZenRAT malware disguised as Bitwarden software. It’s currently unknown if the malware is used by threat actors for cyberespionage or for financial fraud.

We’ll delve into the technical details and share more information from Proofpoint researchers, as well as provide tips on mitigating this ZenRAT malware threat.

Jump to:

What is ZenRAT malware, and what happens when it’s executed?

ZenRAT is malware developed in .NET. It was previously unreported and specifically targets Microsoft Windows operating systems. Once executed, the ZenRAT malware queries the system to gather information:

  • CPU and GPU names.
  • Operating system version.
  • RAM capabilities.
  • IP address and gateway IP address.
  • Installed software including antivirus.

The data is sent as a ZIP archive file to its command and control server, along with stolen browser data and credentials. The ZIP file contains two files named InstalledApps.txt and SysInfo.txt. Proofpoint told TechRepublic that they ” … observed ZenRAT stealing data from both Chrome and Firefox” and believe “It’s reasonable to assume that it would have support for most Chromium-based browsers.”

The malware executes several checks when running. For starters, it checks that it doesn’t operate from Belarus, Kyrgyzstan, Kazakhstan, Moldova, Russia or Ukraine.

Then, the malware ensures it doesn’t already run on the system by checking for a specific mutex and that the hard drive isn’t less than 95GB in size, which might indicate a sandbox system to the malware. It also checks for known virtualization products’ process names to verify it isn’t running in a virtualized environment.

Once the checks have been passed, the malware sends a ping command to be sure it’s connected to the internet, and checks if there is an update for the malware.

In addition, the malware has the ability to send its log files to the C2 server in clear text, probably for debugging…
