模拟构建漏洞 PDF 响应载荷后发现，该载荷可异常驻留并嵌入 Adobe Acrobat Reader 内部，即便关闭 PDF、重启软件乃至操作系统，仍能持续触发恶意代码执行。

A well-known Iran-linked hacking group has been caught running a far-reaching espionage campaign that touched at least nine organizations across nine countries and four continents in early 2026. The attackers used a clever trick to hide inside targeted networks: they abused legitimate, signed software to secretly load malicious code, making their activity look like normal […]

结合简单模型实验，直指漏洞利用

该文章介绍了一道 Node.js CTF 题目的解题思路：攻击者首先利用 /changepassword 接口的 merge() 函数原型链污染漏洞，注入 isAdmin: true 提权为管理员；随后通过 CVE-2026-22709 绕过 vm2 沙箱执行任意命令；最后利用 root 权限的 /backup.sh 定时脚本，将 /flag 内容写入静态目录实现读取。核心链：原型污染提权 → v

The cybersecurity industry of 2006 barely resembled today's billion-dollar behemoth. As part of Dark Reading's 20th anniversary celebration, we trace the industry's evolution through a technology lens.

New guidance explains how to design Zero Trust Network Access architectures aligned with zero trust principles and not built on old trust assumptions.

CISA has added three new vulnerabilities to its Known Exploited Vulnerabilities (KEV) Catalog, based on evidence of active exploitation.

• CVE-2026-8398 Daemon Tools Lite Embedded Malicious Code Vulnerability
• CVE-2026-45321 TanStack Unspecified Vulnerability
• CVE-2026-48027 Nx Console Embedded Malicious Code Vulnerability

These types of vulnerabilities are frequent attack vectors for malicious cyber actors and pose significant risks to the federal enterprise.

Binding Operational Directive (BOD) 22-01: Reducing the Significant Risk of Known Exploited Vulnerabilities established the KEV Catalog as a living list of known Common Vulnerabilities and Exposures (CVEs) that carry significant risk to the federal enterprise. BOD 22-01 requires Federal Civilian Executive Branch (FCEB) agencies to remediate identified vulnerabilities by the due date to protect FCEB networks against active threats. See the BOD 22-01 Fact Sheet for more information.

Although BOD 22-01 only applies to FCEB agencies, CISA strongly urges all organizations to reduce their exposure to cyberattacks by prioritizing timely remediation of KEV Catalog vulnerabilities as part of their vulnerability management practice. CISA will continue to add vulnerabilities to the catalog that meet the specified criteria.

The FBI warned on Tuesday that the Silent Ransom Group (SRG) extortion gang is now targeting U.S.-based law firms in in-person data theft attacks. [...]

Attackers are hosting counterfeit installers and plugins on GitHub and SourceForge that pose as widely used software, including ChatGPT, Claude, AutoTune, Kontakt, Ableton Live, and ZENOLOGY. The downloads deliver a backdoor called DinDoor, which then loads a remote access Trojan built on the Deno JavaScript runtime, according to Malwarebytes. Compromised YouTube channels push victims toward the malicious repositories. The videos promoting the fake tools have accumulated more than 50,000 views. The attackers rotate through GitHub … More →
