Artificial Intelligence (AI) company Anthropic announced a new cybersecurity initiative called Project Glasswing  that will use a preview version of its new frontier model, Claude Mythos , to find and address security vulnerabilities. The model will be used by a small set of organizations, including Amazon Web Services, Apple, Broadcom, Cisco, CrowdStrike, Google, JPMorgan Chase, the Linux Foundation, Microsoft, NVIDIA, and Palo Alto Networks, along with Anthropic, to secure critical software. The company said it's forming this initiative in response to capabilities observed in its general-purpose frontier model that demonstrate a "level of coding capability where they can surpass all but the most skilled humans at finding and exploiting software vulnerabilities." Because of its cybersecurity capabilities and concerns that they could be abused, Anthropic has opted not to make the model generall...

As AI tools become more accessible, employees are adopting them without formal approval from IT and security teams. While these tools may boost productivity, automate tasks, or fill gaps in existing workflows, they also operate outside the visibility of security teams, bypassing controls and creating new blind spots in what is known as shadow AI. While similar to the phenomenon of shadow IT, shadow AI goes beyond unapproved software by involving systems that process, generate, and potentially retain sensitive data. The result is a category of risk that most organizations are not yet equipped to govern: uncontrolled data exposure, expanded attack surfaces, and weakened identity security. Why shadow AI is spreading so quickly Shadow AI is expanding rapidly across organizations because it is easy to adopt and instantly useful, yet largely unregulated. Unlike traditional enterprise software, most AI tools require little to no setup, allowing employ...

Threat activity this week shows one consistent signal — attackers are leaning harder on what already works. Instead of flashy new exploits, many operations are built around quiet misuse of trusted tools, familiar workflows, and overlooked exposures that sit in plain sight. Another shift is how access is gained versus how it’s used. Initial entry points are getting simpler, while post-compromise activity is becoming more deliberate, structured, and persistent. The objective is less about disruption and more about staying embedded long enough to extract value. There’s also growing overlap between cybercrime, espionage tradecraft, and opportunistic intrusion. Techniques are bleeding across groups, making attribution harder and defense baselines less reliable. Below is this week’s ThreatsDay Bulletin — a tight scan of the signals that matter, distilled into quick reads. Each item adds context to where threat pressure is building next.

Cyber threats last week showed how attackers no longer need big hacks to cause big damage. They’re going after the everyday tools we trust most — firewalls, browser add-ons, and even smart TVs — turning small cracks into serious breaches. The real danger now isn’t just one major attack, but hundreds of quiet ones using the software and devices already inside our networks. Each trusted system can become an entry point if it’s left unpatched or overlooked. Here’s a clear look at the week’s biggest risks, from exploited network flaws to new global campaigns and fast-moving vulnerabilities. ⚡ Threat of the Week Flaws in Multiple Network Security Products Come Under Attack — Over the past week, Fortinet , SonicWall , Cisco , and WatchGuard said vulnerabilities in their products have been exploited by threat actors in real-world attacks. Cisco said attacks exploiting CVE-2025-20393, a critical flaw in AsyncOS, have been abused by a China-nexus advanced persistent threat (APT) actor cod...

This week is not about one big event. It shows where things are moving. Network systems, cloud setups, AI tools, and common apps are all being pushed in different ways. Small gaps in access control, exposed keys, and normal features are being used as entry points. The pattern becomes clear only when you see everything together. Faster scans, smarter misuse of trusted services, and steady targeting of high-value sectors. Each story adds context. Reading them all gives a fuller picture of how today’s threat landscape is evolving. ⚡ Threat of the Week Cisco SD-WAN Zero-Day Exploited — A newly disclosed maximum-severity security flaw in Cisco Catalyst SD-WAN Controller (formerly vSmart) and Catalyst SD-WAN Manager (formerly vManage) has come under active exploitation in the wild as part of malicious activity that dates back to 2023. The vulnerability, tracked as CVE-2026-20127 (CVSS score: 10.0), allows an unauthenticated remote attacker to bypass authentication and obtain administr...

This week showed just how fast things can go wrong when no one’s watching. Some attacks were silent and sneaky. Others used tools we trust every day — like AI, VPNs, or app stores — to cause damage without setting off alarms. It’s not just about hacking anymore. Criminals are building systems to make money, spy, or spread malware like it’s a business. And in some cases, they’re using the same apps and services that businesses rely on — flipping the script without anyone noticing at first. The scary part? Some threats weren’t even bugs — just clever use of features we all take for granted. And by the time people figured it out, the damage was done. Let’s look at what really happened, why it matters, and what we should all be thinking about now. ⚡ Threat of the Week Silently Patched Fortinet Flaw Comes Under Attack — A vulnerability that was patched by Fortinet in FortiWeb Web Application Firewall (WAF) has been exploited in the wild since early October 2025 by threat actors to c...

Cybersecurity today moves at the pace of global politics. A single breach can ripple across supply chains, turn a software flaw into leverage, or shift who holds the upper hand. For leaders, this means defense isn’t just a matter of firewalls and patches—it’s about strategy. The strongest organizations aren’t the ones with the most tools, but the ones that see how cyber risks connect to business, trust, and power. This week’s stories highlight how technical gaps become real-world pressure points—and why security decisions now matter far beyond IT. ⚡ Threat of the Week Popular Password Managers Affected by Clickjacking — Popular password manager plugins for web browsers have been found susceptible to clickjacking security vulnerabilities that could be exploited to steal account credentials, two-factor authentication (2FA) codes, and credit card details under certain conditions. The technique has been dubbed Document Object Model (DOM)-based extension clickjacking by independent sec...
