The U.S. Cybersecurity and Infrastructure Security Agency (CISA) on Tuesday added a security flaw impacting the WinRAR file archiver and compression utility to its Known Exploited Vulnerabilities (KEV) catalog, citing evidence of active exploitation. The vulnerability, tracked as CVE-2025-6218 (CVSS score: 7.8), is a path traversal bug that could enable code execution. However, for exploitation

Microsoft closed out 2025 with patches for 56 security flaws in various products across the Windows platform, including one vulnerability that has been actively exploited in the wild. Of the 56 flaws, three are rated Critical, and 53 are rated Important in severity. Two other defects are listed as publicly known at the time of the release. These include 29 privilege escalation, 18 remote code

The Patch Tuesday for December of 2025 includes 57 vulnerabilities, including two that Microsoft marked as “critical.” The remaining vulnerabilities listed are classified as “important.” Microsoft assessed that exploitation of the two “critical” vulnerabilities is “less likely.”

Threat actors with ties to North Korea have likely become the latest to exploit the recently disclosed critical security React2Shell flaw in React Server Components (RSC) to deliver a previously undocumented remote access trojan dubbed EtherRAT. "EtherRAT leverages Ethereum smart contracts for command-and-control (C2) resolution, deploys five independent Linux persistence mechanisms, and

The threat actor known as Storm-0249 is likely shifting from its role as an initial access broker to adopt a combination of more advanced tactics like domain spoofing, DLL side-loading, and fileless PowerShell execution to facilitate ransomware attacks. "These methods allow them to bypass defenses, infiltrate networks, maintain persistence, and operate undetected, raising serious concerns for

The NCSC warns that prompt injection is unlikely to be mitigated in the same way SQL injection was. How do they compare?

Cisco Talos has uncovered a new DeadLock ransomware campaign using a previously unknown BYOVD loader to exploit a Baidu Antivirus driver vulnerability, letting threat actors disable EDR defenses and escalate attacks.

Canadian organizations have emerged as the focus of a targeted cyber campaign orchestrated by a threat activity cluster known as STAC6565. Cybersecurity company Sophos said it investigated almost 40 intrusions linked to the threat actor between February 2024 and August 2025. The campaign is assessed with high confidence to share overlaps with a hacking group known as Gold Blade, which is also

Cybersecurity researchers have discovered two new extensions on Microsoft Visual Studio Code (VS Code) Marketplace that are designed to infect developer machines with stealer malware. The VS Code extensions masquerade as a premium dark theme and an artificial intelligence (AI)-powered coding assistant, but, in actuality, harbor covert functionality to download additional payloads, take

### Impact Versions of CSLA .NET prior to version 6 allow the use of WcfProxy. WcfProxy uses the NetDataContractSerializer (NDCS) which has known vulnerabilities that can allow remote execution of code during deserialization. NDCS itself is considered obsolete, and you should avoid using WcfProxy or upgrade to CSLA 6 or higher where this issue does not exist. ### Patches CSLA .NET version 6 and higher do not use WCF or NetDataContractSerializer. ### Workarounds If you are using a version CSLA .NET older than version 6, you should stop using WcfProxy in your data portal configuration. Doing this avoids the use of WCF and the NetDataContractSerializer, avoiding the vulnerability.
