Unisoc VoLTE Video Call Exploit Chain Can Give Attackers Full Android Kernel Access

Unisoc modem firmware flaw CWE-1189 allows VoLTE video call RCE chain to gain full Android kernel access on T606/T612/T7250 chipsets; no patch yet.

SSD Secure Disclosure published the second stage of an exploit chain, first disclosed in March 2026, that achieves full Android kernel access on Unisoc modem firmware via a VoLTE video call. The privilege-escalation flaw, classified as CWE-1189 (Improper Isolation of Shared Resources on System-on-a-Chip), exploits shared physical memory between modem and application processor with no hardware boundary, letting modem code map the entire 32-bit address space and modify Android kernel pages via ARM Memory Protection Unit registers. Confirmed affected chipsets include Unisoc T606 (Motorola E13), T612 (Realme C33), and T7250 (Xiaomi Redmi A5), sold across more than 140 countries. No CVE has been assigned, the August 2026 Android Security Bulletin does not address it, and Unisoc has not responded to researchers; exploitation requires an attacker-controlled private 4G network and a victim answering the call.

Srsly Risky Biz: China's Private Sector Botnets Are Worth Disrupting

DoJ seized domains of Chinese espionage botnet platforms QScan and QTRouter, run by private firm QTFY for MSS and PLA targeting.

The US Department of Justice disrupted QScan, a distributed vulnerability scanning system with nearly a decade of internet scanning data, and QTRouter, a covert communications platform routing traffic through compromised IoT devices, operated by QTFY under Chinese company Nanjing Xinjiuwei Network Technology. FBI and NSA advisories say QTFY customers include China's Ministry of State Security and the People's Liberation Army, targeting federal agencies, the US Senate, hospitals, telecoms and financial institutions. This is the third Chinese state-backed botnet disrupted since December 2023, following the KV botnet (Volt Typhoon) and Raptor Train (Flax Typhoon), and a sister network, JDY, has more than doubled since the KV disruption. Separately, the Qilin ransomware group claimed a breach of the ATF's CALEA system, briefly publishing 6.3 GB of case folders and forensic data.

China's 'Fire Ant' campaign used compromised Cisco routers as platform for more attacks

Sygnia links the China-nexus Fire Ant campaign to UNC3886, showing hackers weaponized compromised Cisco IOS XR routers for espionage and wider intrusions.

Sygnia's Fire Ant report details Chinese hackers compromising Cisco IOS XR routers, TACACS+ authentication servers and management infrastructure to capture traffic, harvest credentials and stage attacks on high-value and critical infrastructure networks. The group, which overlaps with Mandiant's UNC3886, developed custom router malware for persistence, hid logs, deleted files and tampered with firewall rules, and remained active in 2026 after Sygnia's 2025 disclosure. The activity aligns with prior Chinese campaigns against Cisco devices, including Volt Typhoon and Salt Typhoon operations.

China-Linked Fire Ant Hijacks Cisco Routers to Steal Credentials and Blind Security Logs

China-nexus espionage group Fire Ant compromised Cisco IOS XR routers and TACACS servers to harvest credentials, capture traffic and suppress logs.

Sygnia investigated an intrusion in which Fire Ant expanded beyond VMware hypervisors to Cisco IOS XR routers, TACACS servers and Linux management hosts. The actor deployed purpose-built router implants that hid a GRE tunnel, filtered log messages, captured PCAPs uploaded to external FTP servers, and used TacTap to inject a library into tac_plus and steal TACACS credentials obfuscated with a single-byte XOR key of 0xEF. A Linux backdoor named BridgeAgent masqueraded as a Zabbix agent, persisted via a root systemd unit, disguised itself as /usr/bin/gnome-shell and received commands over TLS on port 443. The group also used Medusa and REPTILE rootkits, SSH backdoors and renamed binaries impersonating SentinelOne and Cybereason agents, while suppressing logs, disabling SELinux and rewriting login history. Sygnia assesses strong overlap with UNC3886 and published IoCs.

CISA Warns Water Utilities: Find Your Exposed PLCs Before Attackers Do

CISA urged water utilities to secure internet-exposed PLCs after July 2026 attacks compromised over 100 US water and wastewater systems, suspected Iran-linked.

CISA's exposure-reduction guidance, published August 21, follows July 2026 attacks in which threat actors remotely accessed PLCs connected directly through cellular modems, changed device IP addresses and passwords, and in some cases disabled alarms and shutdown processes without notifying operators. Iran is the suspected actor, though officials stopped short of formal attribution. CISA recommends routing remote access through centrally managed secure gateways, phishing-resistant MFA, unique credentials, and external scanning of industrial protocols such as Modbus, EtherNet/IP, DNP3, BACnet and OPC UA.

FBI takes down China-linked hacking network behind attacks on NASA, DOJ and U.S. Senate

FBI seized domains disabling QScan and QTRouter malware run by China-linked QTFY group behind intrusions at NASA, DOJ, Senate and other agencies.

The Justice Department and FBI seized domains hard-coded into two malware tools, QScan and QTRouter, operated by a Chinese state-sponsored group called QTFY, tied to a Nanjing-based company that sold hacking services to China's Ministry of State Security and the PLA. QScan infected IoT devices worldwide while QTRouter combined them with commercial proxies and rented servers to build an obfuscation network that masked attack origins. Victims include NASA, the Federal Reserve, the Departments of Energy and Justice, HHS, NIH, and the U.S. Senate. The FBI and NSA published a joint advisory with indicators of compromise, the latest in operations against Mustang Panda, Flax Typhoon, and Volt Typhoon infrastructure.

FBI Seizes China-Linked Hacking Platforms QScan and QTRouter Used Against Critical Infrastructure

FBI seizes China-linked QScan and QTRouter hacking platforms used by QTFY to obfuscate intrusions against US federal agencies.

The DOJ and FBI seized domains hard-coded into QScan and QTRouter, two platforms operated by China-based Nanjing Xinjiuwei Network Technology Company on behalf of state-sponsored group QTFY. QScan automatically infected thousands of IoT devices which were added to QTRouter, an obfuscation network routing malicious traffic through compromised and proxy devices outside China. Targets included NASA, the Federal Reserve, Departments of Energy, Justice, and HHS, NIH, and the US Senate, exploiting flaws in Fortinet SSL-VPN, Citrix ADC, Microsoft Exchange, F5 BIG-IP, Log4j, and others.

US takes down alleged Chinese hacking tools used against Federal Reserve, DOJ and Senate

DOJ takes down QScan and QTRouter Chinese obfuscation platforms used to breach Federal Reserve, DOE, DOJ, and Senate since 2018.

The DOJ and FBI seized domains hard-coded into QScan and QTRouter, platforms run by Nanjing Xinjiuwei Network Technology Company and used by China's Ministry of State Security and PLA. QScan automatically infected IoT devices worldwide which were absorbed into QTRouter, allowing attackers to disguise intrusions as originating from other countries or local sources. Victims included the Federal Reserve, Department of Energy, DOJ, US Senate, NASA, HHS, NIH, plus hospitals, telecoms, power companies, financial institutions, and defense contractors. The FBI investigated QTFY since 2018, tracing a 2019 NASA incident through Pulse Secure VPN exploitation.
