For decades, Microsoft Exchange has been the backbone of business communications, powering emailing, scheduling and collaboration for organizations worldwide. Whether deployed on-premises or in hybrid environments, companies of all sizes rely on Exchange for seamless internal and external communication, often integrating it deeply with their workflows, compliance policies and security frameworks. However, Microsoft has officially announced that support for Exchange Server 2016 and Exchange Server 2019 will end on October 14, 2025. While this may seem like a distant concern, businesses and IT teams must start preparing now. The end of support means that Microsoft will no longer provide security patches, bug fixes or technical support, leaving organizations running on these versions exposed to security vulnerabilities, compliance risks and potential operational disruptions. So, what should businesses do now? In this article, we'll explore the impact of Microsoft's decision, the risks...

Collaboration sits at the essence of SaaS applications. The word, or some form of it, appears in the top two headlines on Google Workspace's homepage. It can be found six times on Microsoft 365's homepage, three times on Box, and once on Workday. Visit nearly any SaaS site, and odds are 'collaboration' will appear as part of the app's key selling point.  By sitting on the cloud, content within the applications is immediately shareable, making it easier than ever to work with others.  However, that shareability is a two-sided coin. On the flip side are often sensitive links sitting on public-facing websites that can be easily accessed. The exposure caused by leaked documents can cause tremendous harm, from competitors trying to gather corporate secrets to whistleblowers sharing internal information with reporters or legislators. As integral as collaboration is to SaaS, sharing links creates a high-risk situation, and real-life breaches, that can be mitigated through the righ...

In a world where threats are persistent, the modern CISO's real job isn't just to secure technology—it's to preserve institutional trust and ensure business continuity. This week, we saw a clear pattern: adversaries are targeting the complex relationships that hold businesses together, from supply chains to strategic partnerships. With new regulations and the rise of AI-driven attacks, the decisions you make now will shape your organization's resilience for years to come. This isn't just a threat roundup; it's the strategic context you need to lead effectively. Here's your full weekly recap, packed with the intelligence to keep you ahead. ⚡ Threat of the Week New HybridPetya Ransomware Bypasses UEFI Secure Boot — A copycat version of the infamous Petya/NotPetya malware dubbed HybridPetya has been spotted. But no telemetry exists to suggest HybridPetya has been deployed in the wild yet. It also differs in one key respect: It can compromise the secure boot featu...

If you use a smartphone, browse the web, or unzip files on your computer, you are in the crosshairs this week. Hackers are currently exploiting critical flaws in the daily software we all rely on—and in some cases, they started attacking before a fix was even ready. Below, we list the urgent updates you need to install right now to stop these active threats. ⚡ Threat of the Week Apple and Google Release Fixes for Actively Exploited Flaws — Apple released security updates for iOS, iPadOS, macOS, tvOS, watchOS, visionOS, and Safari web browser to address two zero-days that the company said have been exploited in highly targeted attacks. CVE-2025-14174 has been described as a memory corruption issue, while the second, CVE-2025-43529, is a use-after-free bug. They can both be exploited using maliciously crafted web content to execute arbitrary code. CVE-2025-14174 was also addressed by Google in its Chrome browser since it resides in its open-source Almost Native Graphics Layer Engi...

Some of the biggest security problems start quietly. No alerts. No warnings. Just small actions that seem normal but aren't. Attackers now know how to stay hidden by blending in, and that makes it hard to tell when something's wrong. This week's stories aren't just about what was attacked—but how easily it happened. If we're only looking for the obvious signs, what are we missing right in front of us? Here's a look at the tactics and mistakes that show how much can go unnoticed. ⚡ Threat of the Week Apple Zero-Click Flaw in Messages Exploited to Deliver Paragon Spyware — Apple disclosed that a security flaw in its Messages app was actively exploited in the wild to target civil society members in sophisticated cyber attacks. The vulnerability, CVE-2025-43200, was addressed by the company in February as part of iOS 18.3.1, iPadOS 18.3.1, iPadOS 17.7.5, macOS Sequoia 15.3.1, macOS Sonoma 14.7.4, macOS Ventura 13.7.4, watchOS 11.3.1, and visionOS 2.3.1. The Citizen Lab said it u...

Can a harmless click really lead to a full-blown cyberattack? Surprisingly, yes — and that's exactly what we saw in last week's activity. Hackers are getting better at hiding inside everyday actions: opening a file, running a project, or logging in like normal. No loud alerts. No obvious red flags. Just quiet entry through small gaps — like a misconfigured pipeline, a trusted browser feature, or reused login tokens. These aren't just tech issues — they're habits being exploited. Let's walk through the biggest updates from the week and what they mean for your security. ⚡ Threat of the Week Recently Patched Windows Flaw Comes Under Active Exploitation — A recently patched security flaw affecting Windows NTLM has been exploited by malicious actors to leak NTLM hashes or user passwords and infiltrate systems since March 19, 2025. The flaw, CVE-2025-24054 (CVSS score: 6.5), is a hash disclosure spoofing bug that was fixed by Microsoft last month as part of its Patch Tuesday updates...

The modern kill chain is eluding enterprises because they aren't protecting the infrastructure of modern business: SaaS .  SaaS continues to dominate software adoption , and it accounts for the greatest share of public cloud spending. But enterprises and SMBs alike haven't revised their security programs or adopted security tooling built for SaaS.  Security teams keep jamming on-prem pegs into SaaS security holes  The mature security controls CISOs and their teams depended on in the age of on-prem dominance have vanished. Firewalls now protect a small perimeter, visibility is limited, and even if SaaS vendors offer logs, security teams need homegrown middleware to digest them and push into their SIEM.  SaaS vendors do have well-defined security scopes for their products, but their customers must manage SaaS compliance and data governance, identity and access management (IAM), and application controls — the areas where most incidents occur. While this SaaS shared...

LUCR-3 overlaps with groups such as Scattered Spider, Oktapus, UNC3944, and STORM-0875 and is a financially motivated attacker that leverages the Identity Provider (IDP) as initial access into an environment with the goal of stealing Intellectual Property (IP) for extortion. LUCR-3 targets Fortune 2000 companies across various sectors, including but not limited to Software, Retail, Hospitality, Manufacturing, and Telecoms. LUCR-3 does not rely heavily on malware or even scripts; instead, LUCR-3 expertly uses victims' own tools, applications, and resources to achieve their goals. At a high level, Initial Access is gained through compromising existing identities in the IDP (Okta: Identity Cloud, Azure AD / Entra, Ping Identity: PingOne). LUCR-3 uses SaaS applications such as document portals, ticketing systems, and chat applications to learn how the victim organization operates and how to access sensitive information. Using the data they gained from reconnaissance within the SaaS ...
