On November 25, 2024, a third party, from SECURE NETWORK BVTECH, reported the D-Link DSL-3788 hardware revision B2 with firmware version vDSL-3788_fw_revA1_1.01R1B036_EU_EN or below, of a Unauthenticated Remote Code Execution (RCE) vulnerability.
When D-Link became aware of the reported security issues, we promptly started investigating and developing security patches. Patches were release within the 90-day of the report of the vulnerabilities.
On January 14, Nick Tait announced the discovery of six vulnerabilities in rsync, the popular file-synchronization tool. While software vulnerabilities are not uncommon, the most serious one he announced allows for remote code execution on servers that run rsyncd — and possibly other configurations. The bug itself is fairly simple, but this event provides a nice opportunity to dig into it, show why it is so serious, and consider ways the open-source community can prevent such mistakes in the future.
The vulnerabilities were found by two groups of researchers: Simon Scannell, Pedro Gallegos, and Jasiel Spelman from Google's Cloud Vulnerability Research identified five of them, including the most serious one. Aleksei Gorban, a security researcher at TikTok, discovered the sixth — a race condition in how rsync handles symbolic links.
ESET researchers have discovered a vulnerability that allows bypassing UEFI Secure Boot, affecting the majority of UEFI-based systems. This vulnerability, assigned CVE-2024-7344, was found in a UEFI application signed by Microsoft’s Microsoft Corporation UEFI CA 2011 third-party UEFI certificate. Exploitation of this vulnerability leads to the execution of untrusted code during system boot, enabling potential attackers to easily deploy malicious UEFI bootkits (such as Bootkitty or BlackLotus) even on systems with UEFI Secure Boot enabled, regardless of the installed operating system.
Apple recently addressed a macOS vulnerability that allows attackers to bypass System Integrity Protection (SIP) and install malicious kernel drivers by loading third-party kernel extensions.

A vulnerability in DigiEver DS-2105 Pro DVRs is being exploited to spread malware.
The Akamai Security Intelligence Research Team (SIRT) noticed this activity in their honeypots on November 18, 2024.
The vulnerability was originally discovered by Ta-Lun Yen and a CVE identifier has been requested by the Akamai SIRT.
The malware is a Mirai variant that has been modified to use improved encryption algorithms.
We have included a list of indicators of compromise (IoCs) in this blog post to assist in defense against this threat.
