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 MI...

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...

The House Select Committee on China has formally issued an advisory warning of an "ongoing" series of highly targeted cyber espionage campaigns linked to the People's Republic of China (PRC) amid contentious U.S.–China trade talks. "These campaigns seek to compromise organizations and individuals involved in U.S.-China trade policy and diplomacy, including U.S. government agencies, U.S. business organizations, D.C. law firms and think tanks, and at least one foreign government," the committee said . The committee noted that suspected threat actors from China impersonated Republican Party Congressman John Robert Moolenaar in phishing emails sent to trusted counterparts with an aim to deceive them and trick them into opening files and links that would grant them unauthorized access to their systems and sensitive information without their knowledge. The end goal of the attacks was to steal valuable data by abusing software and cloud services to cover up traces...

Threat actors are abusing HTTP client tools like Axios in conjunction with Microsoft's Direct Send feature to form a "highly efficient attack pipeline" in recent phishing campaigns, according to new findings from ReliaQuest. "Axios user agent activity surged 241% from June to August 2025, dwarfing the 85% growth of all other flagged user agents combined," the cybersecurity company said in a report shared with The Hacker News. "Out of 32 flagged user agents observed in this timeframe, Axios accounted for 24.44% of all activity." The abuse of Axios was previously flagged by Proofpoint in January 2025, detailing campaigns utilizing HTTP clients to send HTTP requests and receive HTTP responses from web servers to conduct account takeover (ATO) attacks on Microsoft 365 environments. ReliaQuest told The Hacker News that there is no evidence to suggest these activities are related, adding that the tool is regularly exploited alongside popular phishin...

A new Android malware called RatOn  has evolved from a basic tool capable of conducting Near Field Communication ( NFC ) relay attacks to a sophisticated remote access trojan with Automated Transfer System ( ATS ) capabilities to conduct device fraud. "RatOn merges traditional overlay attacks with automatic money transfers and NFC relay functionality – making it a uniquely powerful threat," the Dutch mobile security company said in a report published today. The banking trojan comes fitted with account takeover functions targeting cryptocurrency wallet applications like MetaMask, Trust, Blockchain.com, and Phantom, while also capable of carrying out automated money transfers abusing George Česko, a bank application used in the Czech Republic. Furthermore, it can perform ransomware-like attacks using custom overlay pages and device locking. It's worth noting that a variant of the HOOK Android trojan was also observed incorporating ransomware-style overlay screens to d...

⚠️ One click is all it takes. An engineer spins up an "experimental" AI Agent to test a workflow. A business unit connects to automate reporting. A cloud platform quietly enables a new agent behind the scenes. Individually, they look harmless. But together, they form an invisible swarm of Shadow AI Agents—operating outside security's line of sight, tied to identities you don't even know exist. And here's the uncomfortable truth: every one of them carries infinite risk. Agents impersonating trusted users. Non-human identities with access you didn't approve. Data leaking across boundaries you thought were locked down. This isn't a futuristic threat. It's happening today, across enterprises everywhere. And they're multiplying faster than your governance can catch up. That's why you can't miss our upcoming panel: Shadow AI Agents Exposed. Secure your seat now - Register Here . Why Shadow AI is Exploding From identity providers to PaaS platforms, it takes almost nothing to spin...

Cybersecurity researchers have disclosed details of a phishing campaign that delivers a stealthy banking malware-turned-remote access trojan called MostereRAT . The phishing attack incorporates a number of advanced evasion techniques to gain complete control over compromised systems, siphon sensitive data, and extend its functionality by serving secondary plugins, Fortinet FortiGuard Labs said. "These include the use of an Easy Programming Language ( EPL ) to develop a staged payload, concealing malicious operations and disabling security tools to prevent alert triggers, securing command-and-control (C2) communications using mutual TLS (mTLS), supporting various methods for deploying additional payloads, and even installing popular remote access tools," Yurren Wan said . EPL is an obscure visual programming language that supports traditional Chinese, simplified Chinese, English, and Japanese variants. It's chiefly meant for users who may not be proficient in English....
