A new Android malware operation called RedWing is being rented out on Telegram as a ready-made bank-fraud service. It lets even low-skill criminals take over a victim's phone, steal their banking logins, and capture the one-time codes that protect their accounts. Zimperium's zLabs , which found the operation, says it looks like a new variant of Oblivion , a $300-a-month rent-a-malware tool documented earlier this year. RedWing is sold as a complete product, in subscription tiers with referral discounts, guides, and how-to videos, so a buyer needs no malware-writing skill. A Telegram bot builds each buyer a custom app on demand. Researchers say a substantial number of the resulting droppers and payloads currently evade conventional security tools. Infection starts with a phishing link that opens a fake app-store page. The kit's dropper builder can mimic Google Play, the Galaxy Store, and AppGallery, or build fully custom pages, complete with fake ratings, reviews, ...

A suspected China-aligned threat activity cluster has been observed exploiting Roundcube webmail software belonging to physics and engineering departments of U.S. and Canadian universities as part of a new campaign. The activity involves the exploitation of now-patched, critical security flaws in the open-source email solution, such as CVE-2024-42009 (CVSS score: 9.3), to siphon credentials, followed by either the deployment of a web shell for persistent access or a known post-exploitation tool called VShell . The emerging threat cluster is being tracked by Proofpoint under the moniker UNK_MassTraction . It was first detected in May 2026, specifically focusing on administrators and professors in departments with either national security ties or entities studying astrophysics and particle physics. "The emails targeting university departments used both compromised senders, as well as abused domains vulnerable to spoofing due to lax DMARC policy to send the emails," the ...

An Iranian hacking group affiliated with Iran's Ministry of Intelligence and Security (MOIS) has been wielding a previously undocumented modular command-and-control (C2) framework dubbed Cavern (aka Cav3rn) targeting Israeli organizations. The activity, which has primarily singled out IT providers and government sectors, has been attributed to a threat cluster tracked by Check Point Research under the moniker Cavern Manticore , which it said shares some level of tactical overlaps with MuddyWater and Lyceum , the latter of which is assessed to be a subgroup within OilRig . "The framework reflects a mature and adaptable toolset built around a shared .NET foundation, while using multiple compilation formats across different components, including .NET Framework, .NET Mixed-Mode C++/CLI, and .NET Native AOT ," the cybersecurity company said . "The compilation format itself becomes the anti-analysis layer that forces reverse engineers into multiple toolsets and me...

A streaming box should not need a threat model. Neither should a username field, a demo repo, a reset flow, or a browser permission prompt. That is the irritating part this week: the risky pieces were ordinary. Home devices became a routing cover. Clean code pulled dirt from a dependency. Identity shortcuts aged badly. AI systems trusted the wrong instructions. Same soft spot throughout: trust placed one layer too early. Below is the full recap, since this is apparently what counted as a normal week. ⚡ Threat of the Week NetNut Residential Proxy Network Disrupted — Google, in collaboration with the U.S. Federal Bureau of Investigation (FBI), Lumen, and other partners, took action against the NetNut residential proxy network, also known as Popa, building upon its takedown of IPIDEA in January 2026. Google said it disabled Google accounts and associated Google services used by NetNut for malware command-and-control (C2) and updated Google Play Protect, in addition to disabling ...

A suspected China-nexus threat activity cluster has been observed targeting Indian taxpayers, tax professionals, and corporate finance teams to deliver a remote access trojan designed to steal sensitive data from compromised hosts. The multi-stage campaign, codenamed Operation DragonReturn by Seqrite Labs, involves sending spear-phishing emails impersonating the Income Tax Department of India. It was first observed on May 18, 2026. The activity, per the cybersecurity company, coincides with the annual income tax filing season in the country. "It is not opportunistic – the precision of the lure document, the use of real legal citations, bilingual content, and active payload rotation indicate a deliberate, resourced, and sustained threat operation focused exclusively on the Indian taxpayer ecosystem," security researchers Dixit Panchal and Soumen Burma said . The end goal of the campaign is assessed to be the deployment of malware for financial gain or sensitive data the...
