Japan's CERT coordination center (JPCERT/CC) on Thursday revealed it observed incidents that involved the use of a command-and-control (C2) framework called CrossC2, which is designed to extend the functionality of Cobalt Strike to other platforms like Linux and Apple macOS for cross-platform system control. The agency said the activity was detected between September and December 2024, targeting

Microsoft today released updates to fix more than 100 security flaws in its Windows operating systems and other software. At least 13 of the bugs received Microsoft's most-dire "critical" rating, meaning they could be abused by malware or malcontents to gain remote access to a Windows system with little or no help from users.

Time-of-check time-of-use (toctou) race condition in Windows Subsystem for Linux allows an authorized attacker to elevate privileges locally.

Cybersecurity researchers have disclosed vulnerabilities in select model webcams from Lenovo that could turn them into BadUSB attack devices. "This allows remote attackers to inject keystrokes covertly and launch attacks independent of the host operating system," Eclypsium researchers Paul Asadoorian, Mickey Shkatov, and Jesse Michael said in a report shared with The Hacker News. The

Talos reported 5 vulnerabilities to Broadcom and Dell affecting both the ControlVault3 Firmware and its associated Windows APIs that we are calling “ReVault”.

Cybersecurity researchers have discovered a set of 11 malicious Go packages that are designed to download additional payloads from remote servers and execute them on both Windows and Linux systems. "At runtime the code silently spawns a shell, pulls a second-stage payload from an interchangeable set of .icu and .tech command-and-control (C2) endpoints, and executes it in memory," Socket security

### Summary `tmp@0.2.3` is vulnerable to an Arbitrary temporary file / directory write via symbolic link `dir` parameter. ### Details According to the documentation there are some conditions that must be held: ``` // https://github.com/raszi/node-tmp/blob/v0.2.3/README.md?plain=1#L41-L50 Other breaking changes, i.e. - template must be relative to tmpdir - name must be relative to tmpdir - dir option must be relative to tmpdir //<-- this assumption can be bypassed using symlinks are still in place. In order to override the system's tmpdir, you will have to use the newly introduced tmpdir option. // https://github.com/raszi/node-tmp/blob/v0.2.3/README.md?plain=1#L375 * `dir`: the optional temporary directory that must be relative to the system's default temporary directory. absolute paths are fine as long as they point to a location under the system's default temporary directory. Any directories along the so specified path must exist, otherwise a ENOENT error will be...
