TAG-182, an Iran-nexus threat cluster, is conducting surveillance operations targeting Iranian citizens both domestically and abroad using MarkiRAT malware. The group distributes fake Android applications masquerading as VPN services and media players through social media platforms, particularly Instagram. Following Iran's partial internet restoration in May 2026 after an 88-day shutdown, these surveillance activities have intensified as Iranian security apparatus seeks to monitor perceived dissidents and anti-government activists. MarkiRAT samples demonstrate tradecraft overlaps with previously documented Ferocious Kitten operations, including use of Background Intelligent Transfer Service (BITS). The group operates infrastructure across multiple autonomous systems, utilizing domains with naming conventions mimicking legitimate services like Microsoft, Google, and Facebook.

A sophisticated multi-stage intrusion campaign was identified leveraging a weaponized PowerShell payload disguised as a JPEG image file (sysupdate.jpeg) to deploy a trojanized ConnectWise ScreenConnect instance for covert remote access. The attack likely originates through social engineering techniques including phishing emails or malicious attachments. Upon execution, the malware establishes a staging environment, retrieves additional payloads from attacker-controlled infrastructure, and dynamically compiles a custom launcher using Microsoft's legitimate .NET compiler (csc.exe) to evade detection. The intrusion abuses ComputerDefaults.exe and a malicious ms-settings registry hijack to perform a fileless UAC bypass and obtain elevated privileges. Once elevated, the malware deploys a persistent service masquerading as OneDriveServers and launches a modified ScreenConnect framework capable of credential interception, remote command execution, surveillance operations, SYSTEM-level execution, encrypted command...

APT37, a DPRK-backed threat group, has launched a new campaign called Ruby Jumper, utilizing Windows shortcut files to initiate attacks with newly discovered tools. These tools include RESTLEAF, SNAKEDROPPER, THUMBSBD, and VIRUSTASK, which work together to deliver surveillance payloads like FOOTWINE and BLUELIGHT. The campaign leverages removable media to infect and communicate with air-gapped systems. Key features include the use of Ruby for shellcode-based payloads, abuse of cloud storage services for command and control, and sophisticated techniques for bypassing network isolation. The malware demonstrates advanced capabilities in system reconnaissance, data exfiltration, and persistent surveillance.

A new Python-based Remote Access Trojan (RAT) named 'Nursultan Client' targets gamers by masquerading as a legitimate Minecraft client. It uses the Telegram Bot API for command and control, enabling attackers to capture screenshots, access webcams, steal Discord authentication tokens, open URLs, and perform system reconnaissance on Windows machines. Although it attempts persistence, its implementation has flaws. The malware's focus on Discord tokens and gaming users suggests a Malware-as-a-Service model, likely sold to other threat actors. No known exploits in the wild have been reported yet. The threat poses a medium severity risk but could escalate if customized versions improve persistence or evasion. European organizations with gaming communities or employees using Discord and Minecraft are at risk, especially in countries with high gaming engagement and Discord usage. Mitigation requires targeted detection of the fake client, monitoring Telegram API usage, and securing Discord tokens. Countries like Germany, France, the UK, and the Netherlands are most likely affected due to their large gaming populations and technology adoption. The threat is medium severity given its impact on confidentiality and moderate ease of exploitation without user interaction beyond initial infection.

APT37, a North Korean threat actor, has been observed using new tactics and tools in recent campaigns. They have deployed a Rust-based backdoor named Rustonotto, alongside the existing PowerShell-based Chinotto malware and FadeStealer. The group utilizes Windows shortcut files and help files as initial infection vectors. Their sophisticated attack chain includes spear phishing, Compiled HTML Help file delivery, and Transactional NTFS for stealthy code injection. The threat actor employs a single command-and-control server to orchestrate all components of their malware arsenal. FadeStealer, a surveillance tool, is capable of logging keystrokes, capturing screenshots and audio, tracking devices, and exfiltrating data through password-protected RAR archives.

A sophisticated Android backdoor named Android.Backdoor.916.origin is targeting Russian business representatives. The malware, disguised as an antivirus app called 'GuardCB', has extensive surveillance capabilities including intercepting calls, streaming camera footage, stealing data from messaging apps and browsers, and keylogging. Distributed via messenger apps, it requests numerous system permissions and connects to C2 servers for commands. The backdoor can transmit SMS messages, contact lists, call logs, location data, and captured audio/video streams. It uses Accessibility Service to log keystrokes and intercept content from specific apps like Telegram and Chrome. The malware is believed to be used for targeted attacks rather than mass distribution.

Parental control apps, designed to protect children online, are gaining popularity but raising concerns about privacy and misuse. These apps require extensive permissions to monitor device activities, including location tracking, call logs, and message access. While some are distributed through official app stores, others are available directly from developer websites. Concerns arise from apps being used for spousal surveillance or privacy breaches. The article discusses app features, distribution methods, and promotion tactics, noting that some apps advertise capabilities beyond child protection. It also highlights methods used to prevent app removal and ways to bypass antivirus detection. The piece concludes by advising caution when installing such apps and recommending regular security scans to protect against potential threats.

Lookout Threat Lab has uncovered a mobile forensics application called Massistant, used by Chinese law enforcement to extract extensive data from mobile devices. Believed to be the successor of MFSocket, Massistant requires physical access to install and is not distributed through official app stores. It collects sensitive information including GPS data, SMS messages, images, audio, contacts, and phone services. The tool is associated with Xiamen Meiya Pico Information Co., Ltd., a Chinese technology company controlling a significant portion of China's digital forensics market. Massistant introduces new features like Accessibility Services to bypass device security prompts and support for additional messaging apps. The discovery raises concerns about data privacy for travelers to China, as law enforcement can potentially access and analyze confiscated devices without a warrant.

A new Go-based Linux botnet named PumaBot has been identified targeting IoT devices, particularly surveillance systems. It brute-forces SSH credentials using lists from a C2 server, then deploys itself and establishes persistence. The malware disguises itself as legitimate system files, creates systemd services, and adds SSH keys for backdoor access. It also includes components for credential theft and system monitoring. The botnet demonstrates sophisticated evasion techniques and aims for long-term access to compromised devices.
