Cybersecurity researchers have discovered two new malware families, including a modular Apple macOS backdoor called CHILLYHELL and a Go-based remote access trojan (RAT) named ZynorRAT that can target both Windows and Linux systems. According to an analysis from Jamf Threat Labs, ChillyHell is written in C++ and is developed for Intel architectures. CHILLYHELL is the name assigned to a malware that's attributed to an uncategorized threat cluster dubbed UNC4487. The hacking group is assessed to have been active since at least October 2022. According to threat intelligence shared by Google Mandiant, UNC4487 is a suspected espionage actor that has been observed compromising the websites of Ukrainian government entities to redirect and socially engineer targets to execute Matanbuchus or CHILLYHELL malware. The Apple device management company said it discovered a new CHILLYHELL sample uploaded to the VirusTotal malware scanning platform on May 2, 2025. The artifact, notarized ...

Microsoft on Tuesday addressed a set of 80 security flaws in its software, including one vulnerability that has been disclosed as publicly known at the time of release. Of the 80 vulnerabilities, eight are rated Critical and 72 are rated Important in severity. None of the shortcomings has been exploited in the wild as a zero-day. Like last month , 38 of the disclosed flaws are related to privilege escalation, followed by remote code execution (22), information disclosure (14), and denial-of-service (3). "For the third time this year, Microsoft patched more elevation of privilege vulnerabilities than remote code execution flaws," Satnam Narang, senior staff research engineer at Tenable, said. "Nearly 50% (47.5%) of all bugs this month are privilege escalation vulnerabilities." The patches are in addition to 12 vulnerabilities addressed in Microsoft's Chromium-based Edge browser since the release of August 2025's Patch Tuesday update, including a securit...

Apple on Tuesday revealed a new security feature called Memory Integrity Enforcement (MIE) that's built into its newly introduced iPhone models, including iPhone 17 and iPhone Air. MIE, per the tech giant, offers "always-on memory safety protection" across critical attack surfaces such as the kernel and over 70 userland processes without sacrificing device performance by designing its A19 and A19 Pro chips keeping this aspect in mind. "Memory Integrity Enforcement is built on the robust foundation provided by our secure memory allocators, coupled with Enhanced Memory Tagging Extension (EMTE) in synchronous mode, and supported by extensive Tag Confidentiality Enforcement policies," the company noted . The effort is an aim to improve memory safety and prevent bad actors, specifically those leveraging mercenary spyware , from weaponizing such flaws in the first place to break into devices as part of highly-targeted attacks. The technology that underpins MIE...

Introduction Managed service providers (MSPs) and managed security service providers (MSSPs) are under increasing pressure to deliver strong cybersecurity outcomes in a landscape marked by rising threats and evolving compliance requirements. At the same time, clients want better protection without managing cybersecurity themselves. Service providers must balance these growing demands with the need to work efficiently, deliver consistent results, and scale their offerings. Yet, many service providers still rely on manual processes that slow down delivery, make it harder to maintain consistency across clients, and limit the time teams have to focus on more strategic initiatives. Even experienced service providers can find themselves stretched thin as they try to meet rising client expectations while managing operational complexity. In this environment, automation offers an opportunity to work more effectively and deliver greater value. By streamlining repetitive tasks, improving con...

Phishing-as-a-Service (PhaaS) platforms keep evolving, giving attackers faster and cheaper ways to break into corporate accounts. Now, researchers at ANY.RUN has uncovered a new entrant: Salty2FA , a phishing kit designed to bypass multiple two-factor authentication methods and slip past traditional defenses.  Already spotted in campaigns across the US and EU, Salty2FA puts enterprises at risk by targeting industries from finance to energy. Its multi-stage execution chain, evasive infrastructure, and ability to intercept credentials and 2FA codes make it one of the most dangerous PhaaS frameworks seen this year. Why Salty2FA Raises the Stakes for Enterprises Salty2FA’s ability to bypass push, SMS, and voice-based 2FA means stolen credentials can lead directly to account takeover. Already aimed at finance, energy, and telecom sectors, the kit turns common phishing emails into high-impact breaches.  Who is Being Targeted? ANY.RUN analysts mapped Salty2FA campaigns and fo...
