Everyone has cybersecurity stories involving family members. Here's a relatively common one. The conversation usually goes something like this:  "The strangest thing happened to my streaming account. I got locked out of my account, so I had to change my password. When I logged back in, all my shows were gone. Everything was in Spanish and there were all these Spanish shows I've never seen before. Isn't that weird?" This is an example of an account takeover attack on a customer account. Typically what happens is that a streaming account is compromised, probably due to a weak and reused password, and access is resold as part of a common digital black market product, often advertised as something like "LIFETIME STREAMING SERVICE ACCOUNT - $4 USD." In the grand scheme of things, this is a relatively mild inconvenience for most customers. You can reset your credentials with a much stronger password, call your bank to issue a new credit card and be back to binge-watching The Crown i...

Cybersecurity researchers have revealed that RansomHub 's online infrastructure has "inexplicably" gone offline as of April 1, 2025, prompting concerns among affiliates of the ransomware-as-a-service (RaaS) operation. Singaporean cybersecurity company Group-IB said that this may have caused affiliates to migrate to Qilin, given that "disclosures on its DLS [data leak site] have doubled since February."  RansomHub, which first emerged in February 2024, is estimated to have stolen data from over 200 victims. It replaced two high-profile RaaS groups, LockBit and BlackCat, to become a frontrunner, courting their affiliates, including Scattered Spider and Evil Corp , with lucrative payment splits. "Following a possible acquisition of the web application and ransomware source code of Knight (formerly Cyclops), RansomHub quickly rose in the ransomware scene, thanks to the dynamic features of its multi-platform encryptor and an aggressive, affiliate-friendly ...

Various generative artificial intelligence (GenAI) services have been found vulnerable to two types of jailbreak attacks that make it possible to produce illicit or dangerous content. The first of the two techniques, codenamed Inception, instructs an AI tool to imagine a fictitious scenario, which can then be adapted into a second scenario within the first one where there exists no safety guardrails . "Continued prompting to the AI within the second scenarios context can result in bypass of safety guardrails and allow the generation of malicious content," the CERT Coordination Center (CERT/CC) said in an advisory released last week. The second jailbreak is realized by prompting the AI for information on how not to reply to a specific request.  "The AI can then be further prompted with requests to respond as normal, and the attacker can then pivot back and forth between illicit questions that bypass safety guardrails and normal prompts," CERT/CC added. Success...

The U.S. Cybersecurity and Infrastructure Security Agency (CISA) on Monday added two high-severity security flaws impacting Broadcom Brocade Fabric OS and Commvault Web Server to its Known Exploited Vulnerabilities ( KEV ) catalog, citing evidence of active exploitation in the wild. The vulnerabilities in question are listed below - CVE-2025-1976 (CVSS score: 8.6) - A code injection flaw affecting Broadcom Brocade Fabric OS that allows a local user with administrative privileges to execute arbitrary code with full root privileges CVE-2025-3928 (CVSS score: 8.7) - An unspecified flaw in the Commvault Web Server that allows a remote, authenticated attacker to create and execute web shells "Exploiting this vulnerability requires a bad actor to have authenticated user credentials within the Commvault Software environment," Commvault said in an advisory released in February 2025. "Unauthenticated access is not exploitable. For software customers, this means your ...

Not every security vulnerability is high risk on its own - but in the hands of an advanced attacker, even small weaknesses can escalate into major breaches. These five real vulnerabilities, uncovered by Intruder's bug-hunting team, reveal how attackers turn overlooked flaws into serious security incidents. 1. Stealing AWS Credentials with a Redirect Server-Side Request Forgery (SSRF) is a common vulnerability that can have a significant impact, especially in cloud-hosted applications. If a web application fetches resources from user-supplied URLs, care should be taken to ensure attackers can't manipulate requests to access unintended resources. While assessing a home-moving app running in AWS, our team tested common SSRF bypass techniques. The attack chain was as follows: the app sent a webhook request to the attacker's web server, which responded with a 302 redirect to AWS's metadata service. The app followed the redirect and logged the response, which exposed sensitive metadat...

When we talk about identity in cybersecurity, most people think of usernames, passwords, and the occasional MFA prompt. But lurking beneath the surface is a growing threat that does not involve human credentials at all, as we witness the exponential growth of Non-Human Identities (NHIs).  At the top of mind when NHIs are mentioned, most security teams immediately think of Service Accounts . But NHIs go far beyond that. You've got Service Principals , Snowflake Roles , IAM Roles , and platform-specific constructs from AWS, Azure, GCP, and more. The truth is, NHIs can vary just as widely as the services and environments in your modern tech stack, and managing them means understanding this diversity. The real danger lies in how these identities authenticate. Secrets: The Currency of Machines Non-Human Identities, for the most part, authenticate using secrets : API keys, tokens, certificates, and other credentials that grant access to systems, data, and critical infrastructure. Th...

Cybersecurity researchers have disclosed three security flaws in the Rack Ruby web server interface that, if successfully exploited, could enable attackers to gain unauthorized access to files, inject malicious data, and tamper with logs under certain conditions. The vulnerabilities, flagged by cybersecurity vendor OPSWAT, are listed below - CVE-2025-27610 (CVSS score: 7.5) - A path traversal vulnerability that could be used to gain access to all files under the specified root: directory, assuming an attacker can determine the paths to those files CVE-2025-27111 (CVSS score: 6.9) - An improper neutralization of carriage return line feeds ( CRLF ) sequences and improper output neutralization for logs vulnerability that could be used to manipulate log entries and distort log files CVE-2025-25184 (CVSS score: 5.7) - An improper neutralization of carriage return line feeds (CRLF) sequences and improper output neutralization for logs vulnerability that could be used to manipulate...

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...

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...
