Mirage2FA is an active phishing-as-a-service toolkit built to steal Microsoft 365 credentials and authenticated sessions through Adversary-in-the-Middle attacks. Analysis shows 63.7% of identified victims are in the US, with Technology, Manufacturing, and Education among the most targeted industries. The operation generated thousands of compromise events between 2024 and 2026, including stolen session cookies, passwords, and SSO access. Once a Microsoft 365 session is hijacked, attackers gain access to corporate email, sensitive data, and trusted business accounts. The toolkit uses browser-based delivery through .htm, .xhtml, and .svg stagers, QR codes, JavaScript obfuscation, and WebSocket-based AiTM activity. Of 9,426 unique targeted email addresses, 4,532 were potentially compromised, representing approximately 48% success rate.

Mustang Panda orchestrated two concurrent espionage campaigns targeting Indian government entities and hydropower infrastructure between May and June 2026. The campaigns leveraged DLL sideloading via legitimate executables to deploy newly identified malware including SHARDLOADER, MINIRECON, and ZOHOMURK. MINIRECON represents an evolution of Toneshell with WebSocket-based command-and-control capabilities, while ZOHOMURK abuses Zoho WorkDrive cloud services for C2 communications and data exfiltration. Distribution occurred through spear-phishing with lures themed around India-Taiwan cooperation agreements and hydropower projects. The activity demonstrates code overlaps with previous tooling, infrastructure proximity to known operations, and targeting patterns aligned with Chinese strategic intelligence collection priorities. Multiple compromised government systems were identified, with coordination conducted through CERT-In for victim notification and remediation.

A new campaign targeting Ukrainian entities has been identified, attributed to actors linked to Russia. The campaign uses judicial and charity-themed lures to deploy a JavaScript-based backdoor called DRILLAPP, which runs through the Edge browser. This backdoor enables various actions including file manipulation, microphone access, and webcam capture. Two variants of the campaign have been observed, with the second variant introducing additional capabilities. The attackers utilize the browser's capabilities to evade detection and gain access to sensitive resources. The campaign shares tactics with a previously reported Laundry Bear operation, leading to a low-confidence attribution to this group.

A new Android trojan, named NFCShare, has been discovered targeting Deutsche Bank customers through a phishing campaign. The malware, disguised as a banking app update, prompts users to perform a fake card verification process. It exploits NFC technology to steal card data and PINs, which are then exfiltrated to a remote WebSocket endpoint. The trojan's distribution, user flow, and technical analysis are detailed, including its NFC reading capabilities and string obfuscation techniques. The malware shows links to Chinese-linked tooling and similarities to other NFC-based threats. IOCs include hashes, package details, and network indicators.

The Tsundere botnet, discovered in mid-2025, is an active threat targeting Windows users. It utilizes the Ethereum blockchain to retrieve C2 addresses and employs Node.js for its operations. The botnet spreads through MSI installers and PowerShell scripts, often disguised as popular games. It uses AES-256 CBC encryption for communication and can execute dynamic JavaScript code received from the C2 server. The botnet features a marketplace and control panel, allowing users to create and sell customized bots. Attributed to a Russian-speaking actor known as 'koneko', Tsundere is linked to the 123 Stealer and represents an evolution of previous attacks. Its use of smart contracts for C2 infrastructure enhances its resilience, making it a significant emerging threat.

Over the course of three months, Volexity observed UTA0388 using various themes and fictional identities across dozens of spear phishing campaigns. As time passed, Volexity observed UTA0388 broaden their targeting and send emails in a variety of different languages, including English, Chinese, Japanese, French, and German. In most cases, the initial email sent by UTA0388 contained a link to phishing content hosted on a cloud-based service that would lead to malware.

A sophisticated Android banking trojan named RedHook has been discovered targeting Vietnamese users through spoofed government and financial websites. The malware uses WebSocket to communicate with its command-and-control server and supports over 30 remote commands, enabling complete control over compromised devices. RedHook combines phishing, RAT, and keylogging capabilities to exfiltrate credentials and conduct fraud. It abuses Android's MediaProjection API for screen capture and sends data to a live C2 server. The malware's low antivirus detection rate makes it a stealthy and active threat. Code artifacts suggest development by a Chinese-speaking threat actor or group. An exposed AWS S3 bucket revealed operational data dating back to November 2024, indicating a shift from previous scam campaigns to this advanced banking trojan.

DPRK threat actors are targeting Web3 and crypto-related businesses using Nim-compiled binaries and multiple attack chains. The malware, dubbed NimDoor, employs unusual techniques for macOS, including process injection and encrypted WebSocket communications. It uses a novel persistence mechanism leveraging signal handlers and deploys AppleScripts as beacons and backdoors. The attack chain begins with social engineering via Telegram, leading to the execution of malicious scripts and binaries. The malware exfiltrates browser data, Keychain credentials, and Telegram user information. The use of Nim introduces new levels of complexity for analysts, blending complex behavior into binaries with less obvious control flow.

A malicious WordPress plugin named 'wordpress-player.php' has been discovered, affecting at least 26 websites. The plugin injects a hidden HTML5 video player and establishes a WebSocket connection to a command and control server. It redirects visitors to suspicious websites after 4-5 seconds, avoiding execution for logged-in users. The malware uses a fake 'WordPress Core' author name to evade detection. It impacts website integrity through unauthorized redirects, SEO degradation, and potential security risks to visitors. Mitigation steps include thorough scanning, malware removal, credential resets, software updates, and implementing a Web Application Firewall.
