The framework comprises over 20 interconnected payloads that perform UAC bypass, RDP hijacking, browser-extension based credential theft (Rilide), hardware-wallet seed-phrase phishing (SeedHunter), keylogging, and screen/video capture (OkoSpyware), all coordinated through a plugin dispatcher communicating over HTTP/HTTPS C2 channels. The campaign has been active since at least March 2025, continues to evolve its tooling, and shows indicators (geoblocking, Russian code comments, use of Rilide) consistent with Russian-speaking cybercriminal operators.
Banana RAT Evolves: Comparing Two Recent Branches Through ANY.RUN An exposed public index on 198.245.53.26 revealed two evolutionary branches of Banana RAT, a Brazilian banking-oriented RAT. The older branch (May 2026) used static ETW-themed installation paths and a pseudo-Microsoft C2 domain (c.windowns-cdn.com), while the newer branch (June 2026) shifted to randomized install identifiers, VBS-assisted persistence via hidden SYSTEM scheduled tasks, and WebSocket C2 over host-specific testewin.com subdomains derived from the victim's MachineGuid. Exposed backend scripts (servidorcompletopool.py, ofuscador.py) indicate an automated polymorphic payload generation platform. A shared fallback IP (149.56.12.51) anchors both branches to the same operator.
When checking the URL isn’t enough: a Device Code Phishing attack via a Microsoft website Attackers are abusing Microsoft's legitimate Device Authorization Grant (OAuth 2.0 Device Code Flow) to conduct phishing attacks that bypass traditional URL-based anti-phishing defenses. By pre-fetching a device code from Microsoft's identity platform and tricking victims into entering it on the genuine login.microsoftonline.com page, attackers harvest access and refresh tokens that grant persistent access to the victim's Microsoft 365 account. Two campaign variants were observed: one using password-protected PDF attachments impersonating a law firm, and another targeting Brazilian users via open redirects on cacoo.com.
Analysis of Ongoing Ousaban Attacks Targeting the Iberian Peninsula FortiGuard Labs identified an ongoing Ousaban banking Trojan campaign targeting users in Spain and Portugal, delivered via phishing PDFs that redirect victims to geofenced malicious webpages.

Trust Chains Broken at Scale While ClickFix Becomes a Service This week, attackers stopped trying to kick down the front door and instead walked in through the trust chains that hold digital ecosystems together. North Korea's Sapphire Sleet compromised over 140 Mastra npm packages through a single typosquatted dependency, stealing cryptocurrency wallets and planting persistent backdoors on developer machines. The GlassWorm group trojanized Open VSX extensions with WebAssembly malware that uses the Solana blockchain as an unkillable command channel, while SmartApeSG hijacked the Okendo Reviews widget to serve malicious prompts on thousands of e-commerce sites. Even vendor integrations became a liability: the Klue breach exposed Recorded Future client data through a compromised OAuth token connecting a marketing tool to Salesforce. Deception also became an industrial product. The ErrTraffic framework now operates as full Malware-as-a-Service, using blockchain smart contracts to hide its infrastructure and compromised WordPress sites to serve fake error prompts that trick users into running malicious commands. Attackers weaponized trusted AI platforms too—one campaign abused claude.ai's shared chat feature to deliver MacSync infostealer on macOS, while the shai_hulululud npm package uses prompt injection to blind AI-powered security scanners. On the infrastructure side, the FortiBleed campaign cracked credentials for over 73,000 FortiGate firewalls with a 45-GPU cluster, handing attackers valid keys to government and defense networks worldwide. Defenders should immediately hunt for the easy-day-js dependency in their npm projects, reset credentials on any FortiGate firewall, enable Azure AD Graph Activity Logs to close a years-long reconnaissance visibility gap in Microsoft cloud environments, and audit OAuth tokens on all third-party vendor integrations.

Session Hijacking and Developer Tool Poisoning Collapse Authentication Trust This week, attackers proved that multi-factor authentication is no longer a reliable gatekeeper. Campaigns like Tycoon 2FA and Chinese-language PhaaS platforms intercept one-time passwords in real time and steal session tokens to maintain persistent access, while infostealers like EKZ Infostealer harvest browser cookies to bypass authentication entirely. Even when victims reset passwords and revoke sessions, attackers retain access through hidden device registrations — meaning standard incident response playbooks are now incomplete. Developers remain the preferred entry point for supply chain compromise. The Glassworm botnet was disrupted after hiding malware in VSCode extensions and npm packages, while the Megalodon campaign poisoned GitHub Actions workflows across 5,500 repositories. A malicious Sicoob.Sdk NuGet package stole banking certificates from Brazilian developers, and North Korea's Lazarus group compromised the widely used axios npm library — a single attack touching millions of downstream applications. Organizations must move beyond password-and-MFA reliance: adopt hardware security keys, shorten session lifetimes, delete attacker-registered devices before resetting credentials, and audit developer toolchains and CI/CD pipelines for tampering.
Malicious NuGet Package Impersonates Sicoob SDK to Exfiltrate Banking Certificates and Passwords A malicious NuGet package named Sicoob.Sdk impersonated the official C# SDK for the Brazilian financial cooperative Sicoob.
