A new ongoing malware campaign has been observed distributing three different stealers, such as CryptBot, LummaC2, and Rhadamanthys hosted on Content Delivery Network (CDN) cache domains since at...

A threat actor has been using a content delivery network cache to store information-stealing malware in an ongoing campaign targeting systems U.S., the U.K., Germany, and Japan. Cisco Talos assesses with moderate confidence that the campaign is a CoralRaider operation, based on similarities in tactics, techniques, and procedures with past attacks attributed to the threat actor.

Microsoft says Windows 10 updates released since the start of the year are breaking Microsoft Connected Cache node discovery on enterprise networks. "After installing the January 2024 non-security update, released January 23, 2024, or later updates, some Windows devices which use the DHCP Option 235 for discovery of Microsoft Connected Cache nodes in their network might be unable to use the MCC nodes," Microsoft explains.

Boffins based in Germany and Austria have found a flaw in AMD's SEV trusted execution environment that makes it less than trustworthy. A successful attack - which assumes an attacker is running a malicious hypervisor protected by AMD SEV - could allow arbitrary code execution within a guest VM, the exposure of sensitive data, or privilege escalation.

A team of researchers from UC Irvine and Tsinghua University has developed a new powerful cache poisoning attack named 'MaginotDNS,' that targets Conditional DNS resolvers and can compromise entire TLDs top-level domains. The concept of DNS cache poisoning is injecting forged answers into the DNS resolver cache, causing the server to direct users who enter a domain to incorrect IP addresses, potentially leading them to malicious websites without their knowledge.

Acer has confirmed someone broke into one of its servers after a miscreant put up for sale a 160GB database of what's claimed to be the Taiwanese PC maker's confidential information.

Microsoft says Microsoft Edge users will notice improved performance and a smaller disk footprint because the web browser now automatically compresses disk caches. "Beginning with Microsoft Edge 102 on Windows, Microsoft Edge automatically compresses disk caches on devices that meet eligibility checks, to ensure the compression will be beneficial without degrading performance," the Microsoft Edge Team said Wednesday.

The cache-based targeted de-anonymization attack is a cross-site leak that involves the adversary leveraging a service such as Google Drive, Dropbox, or YouTube to privately share a resource with the target, followed by embedding the shared resource into the attack website. The attack, in a nutshell, aims to unmask the users of a website under the attacker's control by connecting the list of accounts tied to those individuals with their social media accounts or email addresses through a piece of shared content.
