One is a vulnerability in the High-Definition Audio Bus Driver in Windows systems that could lead to a denial of service, while the other is a memory corruption issue that exists in a multicasting protocol in Windows 10. [..] For Snort coverage that can detect the exploitation of these vulnerabilities, download the latest rule sets from Snort.org, and our latest Vulnerability Advisories are always posted on Talos Intelligence’s website. --------------------------------------------- https://blog.talosintelligence.com/talos-discovers-denial-of-service-vulner… ∗∗∗ The Cyber Resilience Act, an Accidental European Alien Torts Statute? ∗∗∗ --------------------------------------------- What if someone is harmed by their own government, but the technology used against them was created by a company based in the United States?

Bypassing the Operating System (OS) by providing direct high-speed access to the system’s memory improves efficiency for Graphics processing units (GPUs), Network Interface Cards (NICs), storage devices (e.g. NVMe) and peripheral devices. DMA capable connections include PCI, PCI Express (PCIe), Thunderbolt, FireWire, ExpressCard.

As a spammer, one of the problems with creating your own architecture to deliver mail is that, once the spam starts flowing, these sources (IPs/domains) can be blocked. Spam can more easily find its way into the inbox if it is delivered from an unexpected or legitimate source. Realizing this, many spammers have elected to attack web pages and mail servers of legitimate organizations, so they may use these “pirated” resources to send unsolicited email. --------------------------------------------- https://blog.talosintelligence.com/simple-mail-transfer-pirates/ ∗∗∗ Phishing and Social Engineering: The Human Factor in Election Security ∗∗∗ --------------------------------------------- Discover how phishing and social engineering threaten the 2024 U.S. elections in part three of our Election Cybersecurity series.

Exploitation is facilitated by bypassing previous patches. [..] Based on our analysis, three of these vulnerabilities are, essentially, the same vulnerability with the same root cause. Since the patch bypass we are disclosing today elaborates on those previous disclosures, we’ll outline them now. --------------------------------------------- https://www.rapid7.com/blog/post/2024/09/05/cve-2024-45195-apache-ofbiz-una… ∗∗∗ Watch the Typo: Our PoC Exploit for Typosquatting in GitHub Actions ∗∗∗ --------------------------------------------- In this blog, we explain how we managed to leverage typosquatting in GitHub Actions and got several applications with inadvertent typos to run our ‘fake’ action.

Im ersten Fall kann ein entfernter Angreifer ohne Anmeldung aufgrund von statischen Admin-Zugangsdaten auf Instanzen zugreifen. Mit den Adminrechten des Accounts erlangt ein Angreifer die volle Kontrolle.
