Users of Chinese instant messaging apps like DingTalk and WeChat are the target of an Apple macOS version of a backdoor named HZ RAT. The artifacts "almost exactly replicate the functionality of the Windows version of the backdoor and differ only in the payload, which is received in the form of shell scripts from the attackers' server," Kaspersky researcher Sergey Puzan said. HZ RAT was first

Details have emerged about a now-patched vulnerability in Microsoft 365 Copilot that could enable the theft of sensitive user information using a technique called ASCII smuggling. "ASCII Smuggling is a novel technique that uses special Unicode characters that mirror ASCII but are actually not visible in the user interface," security researcher Johann Rehberger said. "This means that an attacker

We came a cross a clever abuse of Google and Microsoft's services that fooled us for a minute. See if you could have spotted it.

Ubuntu Security Notice 6973-2 - It was discovered that a race condition existed in the Bluetooth subsystem in the Linux kernel, leading to a null pointer dereference vulnerability. A privileged local attacker could use this to possibly cause a denial of service. Several security issues were discovered in the Linux kernel. An attacker could possibly use these to compromise the system.

Ubuntu Security Notice 6972-3 - Yuxuan Hu discovered that the Bluetooth RFCOMM protocol driver in the Linux Kernel contained a race condition, leading to a NULL pointer dereference. An attacker could possibly use this to cause a denial of service. It was discovered that a race condition existed in the Bluetooth subsystem in the Linux kernel, leading to a null pointer dereference vulnerability. A privileged local attacker could use this to possibly cause a denial of service.

Two security vulnerabilities have been disclosed in the open-source Traccar GPS tracking system that could be potentially exploited by unauthenticated attackers to achieve remote code execution under certain circumstances. Both the vulnerabilities are path traversal flaws and could be weaponized if guest registration is enabled, which is the default configuration for Traccar 5, Horizon3.ai

The U.S. Cybersecurity and Infrastructure Security Agency (CISA) has placed a security flaw impacting Versa Director to its Known Exploited Vulnerabilities (KEV) catalog based on evidence of active exploitation. The medium-severity vulnerability, tracked as CVE-2024-39717 (CVSS score: 6.6), is case of file upload bug impacting the "Change Favicon" feature that could allow a threat actor to

Meta Platforms on Friday became the latest company after Microsoft, Google, and OpenAI to expose the activities of an Iranian state-sponsored threat actor, who it said used a set of WhatsApp accounts that attempted to target individuals in Israel, Palestine, Iran, the U.K., and the U.S. The activity cluster, which originated from Iran, "appeared to have focused on political and diplomatic

The proliferation of new top-level domains (TLDs) has exacerbated a well-known security weakness: Many organizations set up their internal Microsoft authentication systems years ago using domain names in TLDs that didn't exist at the time. Meaning, they are continuously sending their Windows usernames and passwords to domain names they do not control and which are freely available for anyone to register. Here's a look at one security researcher's efforts to map and shrink the size of this insidious problem.
