Quick Takeaways Target Shift: Scattered Spider, a known threat actor previously focused on retail, is now actively targeting the US insurance sector, prompting alerts from Google’s Threat Intelligence Group. Tactics and Recent Activity: The group employs sophisticated social engineering techniques, primarily centered on ransomware and data theft extortion, reflecting an uptick in their activity after previous law enforcement actions. Recent Attacks Noted: Following attacks against UK retailers, multiple incidents involving US insurance companies have been identified, indicating a concentrated effort on this new sector. Industry Warning: Insurance companies are advised to be vigilant, especially regarding social engineering schemes aimed at…
Essential Insights Evolving Ransomware Threat: Ransomware attacks now target backup infrastructures first, crippling recovery capabilities by disabling backup agents and exploiting vulnerabilities, making traditional defenses insufficient. Common Vulnerabilities: Inadequate separation and dependence on a single cloud provider for backups significantly heighten risk. Attack techniques include exploiting Active Directory and misconfigurations to access backup systems. 3-2-1-1-0 Backup Strategy: Modern defenses require the 3-2-1-1-0 approach: three data copies, on two media types, with one offsite, one immutable, and zero errors. This ensures resilience against sophisticated attacks. Securing Backup Environments: Best practices for cloud and on-premises backups involve rigorous segmentation, MFA, strict access…
Fast Facts Critical Vulnerability Discovered: CISA warns that multiple discontinued TP-Link routers are affected by command injection vulnerability CVE-2023-33538, with a CVSS score of 8.8, allowing remote attackers to execute arbitrary system commands. No Support for Impacted Devices: The affected TP-Link models, including TL-WR940N and TL-WR841N, have not received software updates since 2018, urging users to discontinue their use. Active Exploitation Noted: PoC exploit code for the vulnerability was published and removed from GitHub, indicating ongoing exploitation risks.

CISOs identify cybersquatting, domain-based attacks, and ransomware as top cybersecurity concerns An overwhelming 98% of chief information security officers (CISOs) expect a surge in cyber attacks over the next three years as organizations face an increasingly complex and artificial intelligence (AI)-driven digital threat landscape. This is according to new research conducted among 300 CISOs, chief information officers (CIOs), and senior IT professionals by CSC, the leading provider of enterprise-class domain and domain name system (DNS) security. The report, “CISO Outlook 2025: Navigating Evolving Domain-Based Threats in an Era of AI and Tightening Regulation,” names cybersquatting, domain and DNS hijacking, and…

A decade ago, only the largest enterprises measured their data in petabytes (1000 TBs). Today, even mid-sized enterprises find themselves navigating through 2-3 petabytes of data. This data isn’t just sitting idly—it’s being accessed by third parties, manipulated and moved by engineers, and even being used to train LLM models. Here’s the catch: securing fast-moving data at such astronomical scales requires a fundamental shift in the way we approach data security, as manual processes are no longer sustainable. ndeed, only a select few have the expertise to manage data at the colossal scale of petabytes. We’re bringing these pioneers together…
