∗∗∗ Talos discovers denial-of-service vulnerability in Microsoft Audio Bus; Potential remote code execution in popular open-source PLC ∗∗∗
---------------------------------------------
Cisco Talos’ Vulnerability Research team recently disclosed two vulnerabilities in Microsoft products that have been patched by the company over the past two Patch Tuesdays. 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.

∗∗∗ Direct Memory Access (DMA) attacks. Risks, techniques, and mitigations in hardware hacking ∗∗∗
---------------------------------------------
DMA allows input-output (I/O) devices to access memory without CPU involvement. 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. Without additional safeguards, DMA can make systems vulnerable to attacks.

∗∗∗ Simple Mail Transfer Pirates: How threat actors are abusing third-party infrastructure to send spam ∗∗∗
---------------------------------------------
Spammers are always looking for creative ways to bypass spam filters. 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.
