SilkParasite is a cyberespionage operation assessed with medium confidence as China-nexus that targeted government bodies across Central Asia. Seven remote access tool families were deployed, five of which were previously undocumented: DriveSilkRAT, CookiETagRAT, NomadRAT, GoginRAT, and NodeEdgeRAT. The toolset is small, modular, and professionally engineered with traces of AI-assisted development. Initial access occurred through malicious Microsoft Office documents delivered via spear-phishing, using regionally tailored lures impersonating government ministries. The operation leveraged DLL sideloading as the primary delivery mechanism and used Google Drive for command-and-control communications to hide within trusted services. Infrastructure analysis identified connections to China Unicom's backbone network, and operational patterns suggest a functioning software organization with maintained build pipelines and careful operational security.

A China-nexus threat actor is targeting Myanmar government personnel and diplomats through Operation QUICSILVER, delivering malware via Virtual Hard Disk files disguised as JPEG images. The campaign uses Burmese-language lures impersonating Myanmar's Information Technology and Cyber Security Department, including graduation ceremony invitations. The multi-stage infection chain begins with a malicious LNK file that abuses ftp.exe to execute scripts, reconstructs payloads from split files, and deploys QUICAgent, a custom Go-based backdoor. The implant retrieves C2 infrastructure through Cloudflare Workers, communicates over HTTP/3 using QUIC protocol, and employs RC4 encryption. Deleted documents recovered from the VHD reveal interest in ASEAN affairs, BIMSTEC, and Myanmar diplomatic activities. Three related campaigns were identified between April and July 2026, sharing similar TTPs and infrastructure.

It can be daunting to determine who’s responsible for showing ads on the websites we visit, or who’s harvesting data from the mobile apps we use every day. That information is already semi-public, but it is not easily parsed and traditionally much of it has remained walled away in the hands of large advertising platforms. Not anymore: A powerful and free new service called DecryptAds scrapes and correlates this adtech data and makes it simple to quickly learn a great deal about the entities that are tracking you. A Decryptads summary of the advertising partnerships declared by espn.com. The newly launched decryptads.com says it is constantly scraping the files that websites and apps make publicly available to disclose the companies that are permitted to run ads or collect user data. These files include: – ads.txt : all of the adtech companies and data brokers that may run ads or harvest data from the site; – app-ads.txt : entities that can harvest data from or display ads on mobile and smart TV apps; – buyers.json/sellers.json : the entities buying, selling or reselling ad inventory for a given site or app. Zach Edwards is chief research officer for DecryptAds and a threat researcher at the security company Infoblox . Edwards said he and two other founders decided the service was needed because the adtech data in these files is generally only useful when it can be cross-referenced to build a more complete picture of the advertising ecosystem for each website or app. “It’s an adtech tool but we’re trying to approach adtech from a security perspective,” Edwards said. “It’s really built for a lot of privacy and security use cases that have been dramatically underserved.” Those use cases, he said, include tracking down the source of malicious ads that try to foist malware on targeted users, identifying ad networks located in adversarial nations, and detecting the fast growing swarms of AI-generated slop websites and apps. And as decryptads.com demonstrates, these potential security and privacy threats are near impossible to detect just by viewing a single apps.txt or app-ads.txt file. “Supply-chain integrity issues rarely live in a single file,” the site explains . “They show up as broken cross-references between ads.txt, app-ads.txt, and sellers.json files; as cloned declaration sets across unrelated domains; as seller removals that only make sense when viewed across exchanges; and even as supply paths in bid logs that never actually appear in any given publisher’s authorized-seller list.” A search in DecryptAds for the hugely popular sports network espn.com reveals 143 ad partners and 19 registered data broker domains are listed within its ads.txt and app-ads.txt files. That data broker information is gradually becoming available because four states — California, Oregon, Texas and Vermont — have recently passed laws requiring data brokers to register if they buy or sell data on consumers from those states. DecryptAds reports that almost half of those data brokers are collecting geolocation data from espn.com visitors who aren’t blocking ads, while another three disclose that they collect device fingerprints and sensitive personal information. A visual representation of the complex ad supply chain declared by espn.com. Image: decryptads.com. HIGH-RISK AD PARTNERS DecryptAds also makes it easy to learn the beneficiaries and national origins of the advertising firms lurking in apps and websites, displaying a conspicuous warning when adtech partners of an app or website are based in “geo-risk” areas like China and Russia, or in countries with strong financial and political ties to both — such as Cyprus and the United Arab Emirates (UAE). According to DecryptAds, espn.com works with four different advertising entities that are based in either Russia, China or the UAE, including the adtech firm Between Digital , which lists a New York address. However, the dossier on Between Digital flags them as a Russian firm, showing that their pub…

The U.S. Federal Communications Commission (FCC) has banned imports of new foreign-made humanoid robots and power inverters, primarily targeting Chinese manufacturers, citing national security and cybersecurity risks. The ban includes advanced humanoid robots, quadruped robots, and power inverters used in renewable energy and data centers. This move aims to secure critical U.S. supply chains and reduce dependency on foreign technology perceived as a risk. Existing devices and previously approved models are not affected. China has criticized the ban as protectionism and pledged to defend its companies. The ban may impact U.S.-China technology collaborations but is unlikely to slow China's domestic humanoid robot development significantly.
