TOP VULNERABILITY THIS WEEK: Emotet returns after a quiet summer
=========================================================
NOTABLE RECENT SECURITY ISSUES
SELECTED BY THE TALOS SECURITY INTELLIGENCE AND RESEARCH GROUP

Title: New Emotet campaign emerges, but protection stays the same
Description: At the beginning of June 2019, Emotet’s operators decided to take an extended summer vacation. Even the command and control (C2) activities saw a major pause in activity. However, as summer draws to a close, Cisco Talos and other researchers started to see increased activity in Emotet’s C2 infrastructure. And as of Sept. 16, 2019, the Emotet botnet has fully reawakened, and has resumed spamming operations once again. The malware still mainly relies on socially engineered spam emails to spread. Once the attackers have swiped a victim’s email, Emotet constructs new attack messages in reply to some of that victim’s unread email messages, quoting the bodies of real messages in the threads.

Title: Aspose PDF API contains multiple remote code execution vulnerabilites
Description: There are multiple remote code execution vulnerabilities in the Aspose.PDF API. Aspose provides a series of APIs for manipulating or converting a large family of document formats. These vulnerabilities exist in APIs that help process PDFs. An attacker could exploit these vulnerabilities by sending a specially crafted, malicious file to the target and trick them into opening it while using the corresponding API.

TOP VULNERABILITY THIS WEEK: Some AMD graphics cards open to remote code execution attacks
=========================================================
NOTABLE RECENT SECURITY ISSUES
SELECTED BY THE TALOS SECURITY INTELLIGENCE AND RESEARCH GROUP

Title: Remote code execution vulnerability in some AMD Radeon cards
Description: A line of AMD Radeon cards contains a remote code execution vulnerability in their ATIDXX64.DLL driver. AMD produces the Radeon line of hardware, which includes graphics cards and graphics processing units. This specific vulnerability exists on the Radeon RX 550 and the 550 Series while running VMWare Workstation 15. An attacker could exploit this vulnerability by supplying a malformed pixel shared inside the VMware guest operating system to the driver. This could corrupt memory in a way that would allow the attacker to gain the ability to remotely execute code on the victim machine.

Voorkom dat Windows Update uw HotSpot tegoed verbruikt

Stel uw Windows 10-internetverbinding in op gemeten

Er is geen regelrechte manier om updates in Windows 10 te stoppen, maar het besturingssysteem begrijpt wel dat bepaalde internetverbindingen afhankelijk zijn van de hoeveelheid gegevens die worden verbruikt – zoals in-flight of hotel-wifi – of een datalimiet hebben – zoals uw mobiele telefoon hotspot. Daarom heeft Windows 10 een ingebouwde optie om deze verbindingen in te stellen als ‘beperkt/gemeten’, waardoor het algemene gegevensgebruik wordt verminderd, inclusief geen automatische downloads voor OS-updates.

U kunt als volgt een verbinding als gemeten aangeven en het automatisch downloaden van Windows 10-updates stoppen:

  1. Open het Start-menu en klik op het tandwielpictogram Instellingen .
  2. Kies Netwerk & internet .
  3. Selecteer aan de linkerkant Wi-Fi . Zorg ervoor dat u bent verbonden met het netwerk dat u wilt instellen als ‘beperkt’ en klik erop.
  4. Onder Verbinding met datalimiet , veeg je op de schakelaar met de tekst Instellen als verbinding met datalimiet .
