Most microsegmentation projects fail before they even get off the ground—too complex, too slow, too disruptive. But Andelyn Biosciences proved it doesn't have to be that way.  Microsegmentation: The Missing Piece in Zero Trust Security   Security teams today are under constant pressure to defend against increasingly sophisticated cyber threats. Perimeter-based defenses alone can no longer provide sufficient protection as attackers shift their focus to lateral movement within enterprise networks. With over 70% of successful breaches involving attackers moving laterally, organizations are rethinking how they secure internal traffic.  Microsegmentation has emerged as a key strategy in achieving Zero Trust security by restricting access to critical assets based on identity rather than network location. However, traditional microsegmentation approaches—often involving VLAN reconfigurations, agent deployments, or complex firewall rules—tend to be slow, operationally disrupt...

Users searching for pirated software are the target of a new malware campaign that delivers a previously undocumented clipper malware called MassJacker, according to findings from CyberArk. Clipper malware is a type of cryware (as coined by Microsoft) that's designed to monitor a victim's clipboard content and facilitate cryptocurrency theft by substituting copied cryptocurrency wallet addresses with an attacker-controlled one so as to reroute them to the adversary instead of the intended target. "The infection chain begins at a site called pesktop[.]com," security researcher Ari Novick said in an analysis published earlier this week. "This site, which presents itself as a site to get pirated software, also tries to get people to download all sorts of malware." The initial executable acts as a conduit to run a PowerShell script that delivers a botnet malware named Amadey , as well as two other .NET binaries, each compiled for 32- and 64-bit architect...

A new malware campaign has been observed leveraging social engineering tactics to deliver an open-source rootkit called r77 . The activity, condemned OBSCURE#BAT by Securonix, enables threat actors to establish persistence and evade detection on compromised systems. It's currently not known who is behind the campaign. The rootkit "has the ability to cloak or mask any file, registry key or task beginning with a specific prefix," security researchers Den Iuzvyk and Tim Peck said in a report shared with The Hacker News. "It has been targeting users by either masquerading as legitimate software downloads or via fake captcha social engineering scams." The campaign is designed to mainly target English-speaking individuals, particularly the United States, Canada, Germany, and the United Kingdom. OBSCURE#BAT gets its name from the fact that the starting point of the attack is an obfuscated Windows batch script that, in turn, executes PowerShell commands to activ...

If you invite guest users into your Entra ID tenant, you may be opening yourself up to a surprising risk.  A gap in access control in Microsoft Entra's subscription handling is allowing guest users to create and transfer subscriptions into the tenant they are invited into, while maintaining full ownership of them.  All the guest user needs are the permissions to create subscriptions in their home tenant, and an invitation as a guest user into an external tenant. Once inside, the guest user can create subscriptions in their home tenant, transfer them into the external tenant, and retain full ownership rights. This stealthy privilege escalation tactic allows a guest user to gain a privileged foothold in an environment where they should only have limited access. Many organizations treat guest accounts as low-risk based on their temporary, limited access, but this behavior, which works as designed, opens the door to known attack paths and lateral movement within the resource t...

Microsoft has shed light on an ongoing phishing campaign that has targeted the hospitality sector by impersonating online travel agency Booking.com using an increasingly popular social engineering technique called ClickFix to deliver credential-stealing malware. The activity, the tech giant's threat intelligence team said, started in December 2024 and operates with the end goal of conducting financial fraud and theft. It's tracking the campaign under the moniker Storm-1865 . "This phishing attack specifically targets individuals in hospitality organizations in North America, Oceania, South and Southeast Asia, and Northern, Southern, Eastern, and Western Europe, that are most likely to work with Booking.com, sending fake emails purporting to be coming from the agency," Microsoft said in a report shared with The Hacker News. The ClickFix technique has become widespread in recent months, as it tricks users into executing malware under the guise of fixing a supposed...

The North Korea-linked threat actor known as ScarCruft is said to have been behind a never-before-seen Android surveillance tool named KoSpy targeting Korean and English-speaking users. Lookout, which shared details of the malware campaign, said the earliest versions date back to March 2022. The most recent samples were flagged in March 2024. It's not clear how successful these efforts were. "KoSpy can collect extensive data, such as SMS messages, call logs, location, files, audio, and screenshots via dynamically loaded plugins," the company said in an analysis. The malicious artifacts masquerade as utility applications on the official Google Play Store, using the names File Manager, Phone Manager, Smart Manager, Software Update Utility, and Kakao Security to trick unsuspecting users into infecting their own devices. All the identified apps offer the promised functionality to avoid raising suspicion while stealthily deploying spyware-related components in the backg...

Two high-severity security flaws have been disclosed in the open-source ruby-saml library that could allow malicious actors to bypass Security Assertion Markup Language (SAML) authentication protections. SAML is an XML-based markup language and open-standard used for exchanging authentication and authorization data between parties, enabling features like single sign-on (SSO), which allows individuals to use a single set of credentials to access multiple sites, services, and apps. The vulnerabilities, tracked as CVE-2025-25291 and CVE-2025-25292 , carry a CVSS score of 8.8 out of 10.0. They affect the following versions of the library - < 1.12.4 >= 1.13.0, < 1.18.0 Both the shortcomings stem from how both REXML and Nokogiri parse XML differently, causing the two parsers to generate entirely different document structures from the same XML input This parser differential allows an attacker to be able to execute a Signature Wrapping attack, leading to an authentication by...

As IT environments grow more complex, IT professionals are facing unprecedented pressure to secure business-critical data. With hybrid work the new standard and cloud adoption on the rise, data is increasingly distributed across different environments, providers and locations, expanding the attack surface for emerging cyberthreats. While the need for a strong data protection strategy has become more critical than ever, organizations find themselves caught in a difficult balancing act. They are struggling to manage the rising costs and complexities of business continuity and disaster recovery (BCDR) while ensuring that their business-critical data remains secure and recoverable. To help IT teams and managed service providers (MSPs) understand how their peers are navigating these challenges, the State of Backup and Recovery Report 2025 has gathered insights from more than 3,000 IT professionals, security experts and administrators worldwide. The report reveals how businesses are tackl...

Meta has warned that a security vulnerability impacting the FreeType open-source font rendering library may have been exploited in the wild. The vulnerability has been assigned the CVE identifier CVE-2025-27363 , and carries a CVSS score of 8.1, indicating high severity. Described as an out-of-bounds write flaw, it could be exploited to achieve remote code execution when parsing certain font files. "An out-of-bounds write exists in FreeType versions 2.13.0 and below when attempting to parse font subglyph structures related to TrueType GX and variable font files," the company said in an advisory. "The vulnerable code assigns a signed short value to an unsigned long and then adds a static value causing it to wrap around and allocate too small of a heap buffer. The code then writes up to 6 signed long integers out of bounds relative to this buffer. This may result in arbitrary code execution." The company did not share any specifics on how the shortcoming is be...

Browser maker Mozilla is urging users to update their Firefox instances to the latest version to avoid facing issues with using add-ons due to the impending expiration of a root certificate. "On March 14, 2025, a root certificate used to verify signed content and add-ons for various Mozilla projects, including Firefox, will expire," Mozilla said . "Without updating to Firefox version 128 or higher (or ESR 115.13 + for ESR users, including Windows 7/8/8.1 and macOS 10.12-10.14 users), this expiration may cause significant issues with add-ons, content signing, and DRM-protected media playback." Mozilla said the latest version of Firefox includes a new root certificate that will prevent this from happening. The update is crucial for all users of Firefox running a version prior to 128, or Extended Support Release (ESR) versions before 115.13, both of which were released on July 9, 2024. This includes all versions of Firefox for Windows, macOS, Linux, and Android...

The China-nexus cyber espionage group tracked as UNC3886 has been observed targeting end-of-life MX Series routers from Juniper Networks as part of a campaign designed to deploy custom backdoors, highlighting their ability to focus on internal networking infrastructure. "The backdoors had varying custom capabilities, including active and passive backdoor functions, as well as an embedded script that disables logging mechanisms on the target device," Google-owned Mandiant said in a report shared with The Hacker News. The threat intelligence firm described the development as an evolution of the adversary's tradecraft, which has historically leveraged zero-day vulnerabilities in Fortinet, Ivanti, and VMware devices to breach networks of interest and establish persistence for remote access. First documented in September 2022, the hacking crew is assessed to be "highly adept" and capable of targeting edge devices and virtualization technologies with the ultima...
