"ESET telemetry shows that it was seen on a few dozen systems in a limited number of organizations." While designed to wipe data across Windows domains it's deployed on, CaddyWiper will use the DsRoleGetPrimaryDomainInformation() function to check if a device is a domain controller. BleepingComputer reports: "This new malware erases user data and partition information from attached drives," ESET Research Labs explained. Newly discovered data-destroying malware was observed earlier today in attacks targeting Ukrainian organizations and deleting data across systems on compromised networks. We truly believe that our community is bigger than just us, and we have demonstrated this through our creation of more than 6,000 high-quality developer tutorials and approximately 30,000 community-generated questions & answers, hosting of community-focused events such as deploy, and support of the open source community through Hacktoberfest and other initiatives. CSS-Tricks will continue operating as a standalone site supported by DigitalOcean, and CSS-Tricks founder Chris Coyier will support CSS-Tricks in an advisory capacity.Īt DigitalOcean we take great pride in our commitment to the developer and startup communities. CSS-Tricks will broaden and complement our existing library of content, furthering DigitalOcean's reach with both frontend and full-stack developers, and supports our community strategy, a key differentiator for DigitalOcean in the cloud computing space.

While the Linux kernel netfilter patch has been made, the patch isn't available yet in all distribution releases.ĭigitalOcean, in a blog post: I am excited to announce that DigitalOcean has acquired the CSS-Tricks website, a learning site with 6,500 articles, videos, guides and other content focused on frontend development. Worse still, it affects recent major distribution releases such as Red Hat Enterprise Linux (RHEL) 8.x Debian Bullseye Ubuntu Linux, and SUSE Linux Enterprise 15.3. How bad? In its advisory, Red Hat said, "This flaw allows a local attacker with a user account on the system to gain access to out-of-bounds memory, leading to a system crash or a privilege escalation threat." So, yes, this is bad. It's listed as Common Vulnerabilities and Exposures ( CVE-2022-25636), and with a Common Vulnerability Scoring System (CVSS) score of 7.8), this is a real badie. This vulnerability is present in the Linux kernel versions 5.4 through 5.6.10. lo) as the bug is triggered before the rule creation fails."

Adding insult to injury, this works even if the hardware being attacked doesn't have offload functionality! That's because, as Gregory wrote to a security list, "Despite being in code dealing with hardware offload, this is reachable when targeting network devices that don't have offload functionality (e.g. A local, unprivileged attacker can use this to cause a denial-of-service (DoS), execute arbitrary code, and cause general mayhem. This problem exists because netfilter doesn't handle its hardware offload feature correctly. It's an essential Linux security program, so when a security hole is found in it, it's a big deal.

Sophos threat researcher Nick Gregory discovered a hole in Linux's netfilter firewall program that's " exploitable to achieve kernel code execution (via ROP ), giving full local privilege escalation, container escape, whatever you want." ZDNet reports: Behind almost all Linux firewalls tools such as iptables its newer version, nftables firewalld and ufw, is netfilter, which controls access to and from Linux's network stack.
