The Evolving Healthcare Cybersecurity Landscape   Healthcare organizations face unprecedented cybersecurity challenges in 2025. With operational technology (OT) environments increasingly targeted and the convergence of IT and medical systems creating an expanded attack surface, traditional security approaches are proving inadequate. According to recent statistics, the healthcare sector experienced a record-breaking year for data breaches in 2024, with over 133 million patient records exposed. The average cost of a healthcare data breach has now reached $11 million, making it the most expensive industry for breaches.  What's changed dramatically is the focus of attackers. No longer content with merely extracting patient records, cybercriminals are now targeting the actual devices that deliver patient care. The stakes have never been higher, with ransomware now representing 71% of all attacks against healthcare organizations and causing an average downtime of 11 days per inc...

The problem is simple: all breaches start with initial access, and initial access comes down to two primary attack vectors – credentials and devices. This is not news; every report you can find on the threat landscape depicts the same picture.  The solution is more complex. For this article, we'll focus on the device threat vector. The risk they pose is significant, which is why device management tools like Mobile Device Management (MDM) and Endpoint Detection and Response (EDR) are essential components of an organization's security infrastructure. However, relying solely on these tools to manage device risk actually creates a false sense of security. Instead of the blunt tools of device management, organizations are looking for solutions that deliver device trust . Device trust provides a comprehensive, risk-based approach to device security enforcement, closing the large gaps left behind by traditional device management solutions. Here are 5 of those limitations and how to ov...

"The official XPRL (Ripple) NPM package was compromised by sophisticated attackers who put in a backdoor to steal cryptocurrency private keys and gain access to cryptocurrency wallets," Aikido Security's Charlie Eriksen said . The malicious code changes have been found to be introduced by a...

Microsoft on Monday announced that it has moved the Microsoft Account (MSA) signing service to Azure confidential virtual machines (VMs) and that it's also in the process of migrating the Entra ID signing service as well. The disclosure comes about seven months after the tech giant said it completed updates to Microsoft Entra ID and MS for both public and United States government clouds to generate, store, and automatically rotate access token signing keys using the Azure Managed Hardware Security Module (HSM) service. "Each of these improvements helps mitigate the attack vectors that we suspect the actor used in the 2023 Storm-0558 attack on Microsoft," Charlie Bell, Executive Vice President for Microsoft Security, said in a post shared with The Hacker News ahead of publication. Microsoft also noted that 90% of identity tokens from Microsoft Entra ID for Microsoft apps are validated by a hardened identity Software Development Kit (SDK) and that 92% of employee pr...

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...

Blockchain is best known for its use in cryptocurrencies like Bitcoin, but it also holds significant applications for online authentication. As businesses in varying sectors increasingly embrace blockchain-based security tools, could the technology one day replace passwords? How blockchain works  Blockchain is a secure way to maintain, encrypt, and exchange digital records of transactions. Its security benefits stem from its decentralized nature: this distributed ledger can be accessed by participants across various nodes , and is unalterable. All users retain control as a group, meaning no single person can change the ledger. How could this provide security benefits? One advantage is the ability to create a 'self-sovereign ID' that alters the way that a user identifies themselves online. Essentially, it creates a private ID for a user that they control, rather than relying on a centralized institution : they can logon to a particular website or service using their identity on...

Introduction Cyber threats targeting supply chains have become a growing concern for businesses across industries. As companies continue to expand their reliance on third-party vendors, cloud-based services, and global logistics networks, cybercriminals are exploiting vulnerabilities within these interconnected systems to launch attacks. By first infiltrating a third-party vendor with undetected security gaps, attackers can establish a foothold, leveraging these weaknesses to penetrate the primary business partners' network. From there, they move laterally through critical systems, ultimately gaining access to sensitive data, financial assets, intellectual property, or even operational controls. Recent high-profile breaches like the 2024 ransomware attack that hit Change Healthcare, one of the world's largest health payment processing companies, demonstrate how attackers disrupted supply chain operations stealing up to 6TB of millions of patients' protected health information (PHI)....
