πŸš€ Glad to present the new release zDNS v0.1.3! πŸŽ‰

Following Zero Trust practices, I recently wrote and am slowly beginning to introduce new β€œblackhole” functionality into the OpenBLD.net DNS ecosystem

zDNS is a DNS server that puts security and control over DNS queries at the center. With new functionality, zDNS now supports regular expressions in hosts.txt files, allowing more flexibility in configuring allowed queries. Now you can use the power of regular expressions to precisely control permissions, including subdomains and patterns.

Main features:

πŸ›‘ Denies all DNS queries by default.
βœ… Allows you to configure allowed requests through the hosts.txt file.
πŸ”„ Uses balancing strategies to ensure reliable operation with DNS servers.
πŸ› Easily customizable via YAML configuration.
πŸ”œ Prometheus metrics coming soon

Additional protection of your infrastructure or testing requests with zDNS is possible and may be useful to you! Download the latest version here and start using a DNS server with powerful customization options:

Deceptive Lumma Variant Spreads Distributed on YouTube

Lumma stealer variant and attack method via YouTube, has been known for some time, this stealer targets sensitive information, including user credentials, system details, browser data, and extensions.

The crafted installation ZIP file serves as an effective bait to deliver the payload, exploiting the user's intention to install the application and prompting them to click the installation file without hesitation. URLs from open-source websites throughout the scheme aim to diminish user awareness.

This stealer collect also telemetry! And now it's blocked in OpenBLD.net

Now you are an informed, dear OpenBLD user and hope you will be more careful with YouTube content in the future)

😑 OpenBLD.net - Phobos Ransomware Attack Mitigations

The Federal Bureau of Investigation (FBI), the Cybersecurity and Infrastructure Security Agency (CISA), and the Multi-State Information Sharing and Analysis Center (MS-ISAC) are releasing this joint CSA, to disseminate known TTPs and IOCs associated with the Phobos ransomware variants observed as recently as February 2024...

Phobos actors run executables like 1saas.exe or cmd.exe to deploy additional Phobos payloads that have elevated privileges enabled. Additionally, Phobos actors can use the previous commands to perform various windows shell functions. The Windows command shell enables threat actors to control various aspects of a system, with multiple permission levels required for different subsets of commands.

How to mitigate risks:
- Secure RDP
- Reduce administratiove provigese scoping
- Stay updated
- Use OpenBLD.net or similar services

Technical details on CISA site:
