🔍 Leaked documents reveal how Chinese companies build and sell censorship, surveillance, and propaganda systems, showing that firms such as Geedge work with universities, tailor offerings to different government clients, and even reuse competitors’ infrastructure. The account draws clear parallels with Western vendors that began as academic projects and commercialized via government contracts. These disclosures complicate the image of a purely top-down Great Firewall, highlighting corporate incentives and market dynamics behind tools of control.

🔒 The UK's National Crime Agency will chair the Five Eyes Law Enforcement Group (FELEG) and concentrate on disrupting cybercrime, money laundering and online sexual abuse of children over the next two years. The NCA singled out loosely affiliated native-English networks known as 'The Com', which operate across messaging apps, gaming platforms and forums and share violent and child-abuse material. It also linked these groups to data-theft and extortion campaigns involving actors such as Scattered Spider, ShinyHunters and Lapsus$, citing incidents affecting retailers and luxury brands. FELEG has promoted the UK's Counter Terrorism Policing to full member status to strengthen responses to hybrid threats.

🔒 The House Select Committee on China warned of an ongoing series of targeted cyber-espionage campaigns tied to the PRC that aim at organizations involved in U.S.–China trade talks. Attackers impersonated Rep. John Robert Moolenaar in phishing emails that delivered malware via attachments and links, abusing cloud services and software to conceal activity. The campaign, attributed to APT41, affected trade groups, law firms, think tanks, U.S. government agencies and at least one foreign government.

🕵️ The House Select Committee on Strategic Competition between the US and the CCP says Chinese-affiliated actors impersonated Representative John Moolenaar in multiple recent emails to trusted counterparts, delivering malicious files and links designed to compromise systems. The Committee's technical analysis found the attackers abused cloud services and developer tools to hide activity and exfiltrate data, behaviour it calls state-sponsored tradecraft. A Wall Street Journal report linked one bogus Moolenaar email to the Chinese-associated APT41, and the Committee has shared indicators with the FBI and US Capitol Police. Moolenaar condemned the operations and said the Committee will continue investigative and defensive work to protect sensitive deliberations.

⚠️ The Czech National Cyber and Information Security Agency (NUKIB) is urging operators of critical infrastructure to avoid using Chinese technology or transferring user data to servers in China, citing a reassessed High risk of significant disruption. NUKIB confirmed malicious activity by Chinese cyber-actors, including an APT31 campaign against the Ministry of Foreign Affairs, and warned that Chinese law can permit state access to data held by domestic providers.

🛡️ The U.S. Department of State is offering up to $10 million for information on three Russian FSB officers accused of carrying out cyberattacks against U.S. critical infrastructure. The named individuals — Marat Valeryevich Tyukov, Mikhail Mikhailovich Gavrilov, and Pavel Aleksandrovich Akulov — are tied to the FSB's Center 16, tracked under aliases such as Berserk Bear and Dragonfly. Charged in March 2022, the officers are alleged to have run intrusions from 2012–2017 targeting government agencies and energy firms, and recent activity shows exploitation of CVE-2018-0171 in end-of-life Cisco devices. The State Department directs tips to its Rewards for Justice Tor channel; eligible informants could receive rewards and relocation assistance.

📧 Israeli cybersecurity company Dream has attributed a coordinated, multi-wave spear-phishing campaign to Iranian-aligned operators connected to Homeland Justice, targeting embassies, consulates, and international organizations globally. Attackers used geopolitical lures and 104 unique compromised sender addresses — including a hacked mailbox at the Oman Ministry of Foreign Affairs in Paris — to distribute Microsoft Word documents that prompt users to Enable Content and run embedded VBA macros. The macros drop executables that establish persistence, contact command-and-control servers, and harvest system information; ClearSky has also documented related activity and linked it to prior Iranian techniques.

🔐 Recorded Future’s Insikt Group reports that 53% of attributed vulnerability exploits in H1 2025 were carried out by state-sponsored actors, driven largely by geopolitical aims such as espionage and surveillance. Chinese-linked groups accounted for the largest share, with UNC5221 exploiting numerous flaws—often in Ivanti products. The study found 161 exploited CVEs, 69% of which required no authentication and 48% were remotely exploitable. It also highlights the rise of social-engineering techniques like ClickFix and increasing EDR-evasion methods used by ransomware actors.

🔍 A joint advisory from the UK, US and allied partners attributes widespread cyber-espionage operations to the Chinese APT group Salt Typhoon and alleges assistance from commercial vendors that supplied "cyber-related products and services." The report names Sichuan Juxinhe Network Technology, Beijing Huanyu Tianqiong Information Technology and Sichuan Zhixin Ruijie Network Technology. It warns attackers exploited known vulnerabilities in edge devices to access routers and trusted provider connections, and urges immediate patching, proactive hunting using supplied IoCs, and regular review of device logs.

🛡️ The FBI says the Chinese-linked hacker group Salt Typhoon has been observed operating in at least 80 countries, with activity reported across regions including the UK, Canada, Australia and New Zealand. U.S. authorities disclosed that the actors compromised U.S. telecommunications firms, exfiltrating more than one million connection records and targeting calls and SMS for over 100 Americans. A detailed technical analysis was published with international partners, including Germany's BSI, to help network defenders detect and remediate the intrusion, and U.S. officials now say the activity appears to have been contained.

🔍 Group-IB links a broad cyber-espionage campaign, active since 2023 and ongoing into mid‑2025, to the ShadowSilk cluster targeting Central Asian and Asia‑Pacific government organizations. The operation, which has compromised at least 35 government victims, primarily seeks data theft and distributes stolen material on dark web forums. ShadowSilk uses phishing with password‑protected archives, commodity web panels such as JRAT and Morf Project, and post‑compromise tools like Cobalt Strike and Metasploit. Researchers found indicators of both Russian‑ and Chinese‑language operators and advise stronger email defenses, strict application control, regular patching and proactive threat hunting.

🔎 Group-IB attributes a new cluster dubbed ShadowSilk to recent intrusions against 35 government and related organizations across Central Asia and APAC. The operators employ spear-phishing with password-protected archives to deploy a custom loader that conceals command-and-control traffic using Telegram bots and achieves persistence via Windows Registry modifications. Observed tooling includes web shells (ANTSWORD, Behinder, Godzilla, FinalShell), tunneling utilities, Cobalt Strike, and bespoke credential-stealing components used to exfiltrate data.
