🔒 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.

🔒 Workiva notified customers that attackers who accessed a third-party CRM exfiltrated a limited set of business contact data, including names, email addresses, phone numbers, and support ticket content. The company said the Workiva platform and any data within it were not accessed or compromised. Workiva warned customers to remain vigilant for spear‑phishing and reiterated it will not request passwords by text or phone. BleepingComputer reported the incident is tied to recent Salesforce breaches attributed to the ShinyHunters group.

📧 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.

🚨Seqrite Labs has uncovered a spear-phishing campaign named Operation HanKook Phantom attributed to North Korea–linked ScarCruft (APT37). The attacks use ZIP attachments containing malicious Windows LNK shortcuts that masquerade as PDFs and drop a RokRAT backdoor while displaying decoy documents. RokRAT can collect system information, execute commands, enumerate files, capture screenshots, and download further payloads, exfiltrating data via cloud services such as Dropbox, Google Cloud, pCloud, and Yandex Cloud. A second observed variant leverages fileless PowerShell and obfuscated batch scripts to deploy additional droppers and conceal network traffic as browser file uploads.

🛡️ Seqrite attributes a large-scale spear-phishing operation, dubbed Operation HanKook Phantom, to APT37, a North Korea–linked group targeting South Korean government and intelligence personnel. Attackers distributed malicious LNK shortcuts disguised as a legitimate National Intelligence Research Society newsletter and a statement from Kim Yo-jong, which triggered downloads and execution of payloads including RokRAT. The campaign employed in-memory execution, fileless PowerShell, XOR decryption, LOLBins and covert exfiltration techniques to blend with normal traffic and evade detection.

⚠️ Recorded Future's Insikt Group attributes five distinct activity clusters to the actor Blind Eagle (tracked as TAG-144) active between May 2024 and July 2025. The campaigns largely targeted Colombian government agencies across local, municipal, and federal levels using spear-phishing, cracked and open-source RATs (including AsyncRAT, Remcos, DCRat, and Lime RAT) and legitimate internet services for staging. Operators abused dynamic DNS, VPS and VPN services and leveraged geofencing and compromised accounts to redirect or evade detection.

⚠️ Cybersecurity researchers warn of a targeted social‑engineering campaign delivering an in‑memory implant called MixShell to supply‑chain manufacturers through corporate 'Contact Us' forms. The activity, tracked as ZipLine by Check Point, uses weeks of credible exchanges, fake NDAs and weaponized ZIPs containing LNK files that trigger PowerShell loaders. MixShell runs primarily in memory, uses DNS tunneling for C2 with HTTP fallback, and enables remote commands, file access, reverse proxying, persistence and lateral movement. Malicious archives are staged on abused Heroku subdomains, illustrating use of legitimate PaaS for tailored delivery.

🔒 ZipLine is a highly sophisticated social-engineering phishing campaign identified by Check Point Research that reverses the typical attack flow by initiating contact through corporate “Contact Us” forms. Attackers cultivate multi-week, professional email exchanges and often request NDAs before delivering a malicious ZIP containing the in-memory backdoor MixShell. MixShell maintains covert command-and-control via DNS tunneling with HTTP fallback and executes in memory to reduce forensic traces. The campaign primarily targets U.S. manufacturing and supply-chain–critical organizations and has evolved a second wave that uses an AI transformation pretext to increase legitimacy.

🔒 Transparent Tribe (APT36) has been observed delivering weaponized desktop shortcut files to compromise both Windows and BOSS Linux systems at Indian government organizations. Reports from CYFIRMA, CloudSEK, Hunt.io, and Nextron Systems describe Go-based droppers, hex-encoded ELF payloads, and cron-based persistence. The campaign uses spear-phishing lures and typo-squatted domains with decoy PDFs to harvest credentials and target Kavach two-factor authentication, while deploying backdoors such as Poseidon and MeshAgent to maintain long-term access.

🔒 ESET researchers uncovered a previously unknown WinRAR vulnerability, tracked as CVE-2025-8088, that is being actively exploited by the Russia-aligned actor RomCom in targeted spearphishing campaigns. The Windows path traversal flaw enables execution of arbitrary code when victims open crafted archives. Users should update to WinRAR 7.13 immediately and consult ESET's video and blogpost for indicators and mitigation.

🔍 ESET Research describes Gamaredon’s 2024 shift to exclusively target Ukrainian government institutions, significantly increasing spearphishing scale and frequency while adopting new delivery techniques such as malicious hyperlinks and LNK files served from Cloudflare domains. The group introduced six new PowerShell and VBScript-based tools and upgraded existing implants with improved obfuscation, registry-based persistence, and stealth features. Operators have largely hidden C2 infrastructure behind Cloudflare tunnels and increasingly rely on third-party platforms and DoH for resilience.
