Supply-chain security firm Socket has published research findings describing a Go module that posed as a DNS and subdomain scanner while acting as a first-stage Windows malware loader. The firm then traced it to a network of 222 GitHub repositories across 190 accounts. The module published its first version on January 24 this year and has since accumulated more than 1,200 versions, over 700 of them malicious. Socket tracks the campaign as “Operation Muck and Load” and reported the module to the Go security team, which blocked it from the Go module proxy.

Go derives a pseudo-version from the commit timestamp and hash for any commit that lacks a semantic version tag. Socket attributes the sprawl to the threat actor's own GitHub Actions workflow, saying its timed commits could each be resolved as a version, inflating a scanner utility's release history into the hundreds.

Across the confirmed repositories, Socket found the same workflow: it sets the Git email to ischhfd83@rambler.ru, sets the visible commit username to the current repository owner, and then force-pushes a rewritten log file every minute. That split generated owner-attributed activity across disposable accounts while leaving one reusable fingerprint. Socket counted a repository only when both the email and the workflow appeared together, resulting in 222 repositories as the confirmed minimum.

The module's main.go launches a hidden PowerShell command that downloads content from muckcoding.com, decodes it with certutil, and runs the result with execution-policy bypass. Socket describes the decoded script as a multi-layer loader using Base64 encoding and XOR decryption, with a Turkish-language comment in one layer that translates to "run directly, no other step is needed."

Rather than hardcoding a payload URL, the resolver retrieves text from public platforms, searches it for the marker string "LastW," then decrypts the trailing blob with a hardcoded key to recover the actual download location. Primary dead drops include Pastebin and a paste service called Rlim, with fallbacks across YouTube, Instagram, Telegram, Google Docs, and GitCode. If defenders remove one paste or block the final archive URL, the actor can update the resolver content without touching the first-stage loader.

The resolved URL points to a password-protected 7-Zip archive hosted as a GitHub release asset. The loader extracts it into a directory named to resemble a legitimate Microsoft Photos install and launches Microsoft.exe from that path with a hidden window. Decoded payload stages map to AsyncRAT, Quasar, and Remcos-style RAT detections alongside infostealer behavior.

Socket confirmed at least 14 unique malware files across the analyzed set, including Trojan loaders and downloaders, Vidar infostealer, dropper and spyware payloads, and XMRig-related Monero cryptominers. One Loader.exe appeared byte-identically across four separate repositories.

Lure themes span MetaMask and Trust Wallet integrations, seed-phrase utilities, Binance and PayPal automation, Telegram and Discord bots, and game cheats for PUBG, Valorant, and Escape from Tarkov. One PUBG repository, nrevv1lad/Pubg-DESYNC-Menu, presented itself as an external cheat with an installation guide while hosting a Vidar-linked Loader.exe in its source tree.

Socket assesses with high confidence that Operation Muck and Load belongs to the same cluster that Sophos documented in June last year. Sophos researchers Matt Wixey and Andrew O'Donnell traced 141 GitHub repositories, 133 of them backdoored, to the same ischhfd83@rambler.ru address. Sophos also identified "Muck" as one of the actor's aliases, a label now embedded in the muckcoding.com and muckdeveloper.com domains.

Neither GitHub nor the Go team has commented beyond the proxy block.

The Chat Control 1.0 law that enables warrantless mass scanning of digital communications has been voted against multiple times by the EU Parliament. And yet, just like a movie zombie, it keeps getting resurrected by various legal sleight-of-hand moves. Yesterday, one of those tricks worked, as Chat Control 1.0 passed (or rather, was not rejected) in a forced re-vote that required an absolute majority (50% + 1) for active refusal. This brings back the law until 2028, and sets a different stage for September's upcoming discussion on Chat Control 2.0.

After the impending publication in the EU Official Journal, online direct-communication platforms will be allowed to mass-scan their users' data without the need for a warrant, under the guise of looking for child sexual abuse material (CSAM).

The scanning is not mandatory, but big tech firms will have a legal mechanism to rifle through user data. EU firms have historically refrained from doing so, presenting privacy and data sovereignty as selling points, but the legal door is nevertheless now officially open.

The obvious platforms where monitoring can now take place will be e-mail and chat services. Immediate examples include Gmail, iCloud, Hotmail, Discord, Instagram, Slack, Teams, Snapchat, Xbox, and Google Chat.

Although the law's scope is for "interpersonal communications services," the legal mechanism might hypothetically extend to some gray areas like Google Drive, where sending someone a link to a cloud file could be within the scope of the law.

It's worth noting that "direct communication" isn't restricted to one-to-one chats, as it includes group chats; just not public or undirected communications. Additionally, EU law enforcement is still beholden to the same warrant requirement as before — Chat Control 1.0 does not grant a blank pass to authorities to mass-scan user data, or request companies to do so without a targeted warrant.

Thanks to two amendments in yesterday's vote, end-to-end-encrypted (E2EE) communications means (ex: WhatsApp) stay exempt. That means that for now, Chat Control 1.0 isn't a commandment to break encryption, something that has been regularly suggested by lawmakers around the world.

It's as good a time as any to remind people that Instagram messages are no longer E2EE as of May, and that although WhatsApp's messages are encrypted, the service leaks out every single bit of metadata about them — sender, recipient, time, size, etc. As always, Signal is recommended as a privacy-focused communications app.

This latest development in the EU parliament is eliciting widespread public outcry due to the nature of the law itself, but also due to the manner in which it happened. Critics and opponents of the rule are suggesting this move is unprecedented.

Chat Control 1.0 has already been shot down repeatedly, most recently in March. However, European Parliament President Roberta Metsola forced a second reading of the law, and invoked Rule 163's "urgent procedure" mechanism. This had many effects, including bringing up a law that was voted against for discussion yet again; turning the decision into a denial vote (vote-to-deny, not vote-to-pass); exploiting the second-reading requirement that demands an absolute majority vote (50% + 1); and letting the President herself set the schedule. Metsola scheduled the second reading to the very last day before the European Parliament summer recess.

The result was that out of 720 representatives, only 607 actually cast a vote. Of those, 315 (over half) voted against Chat Control 1.0. That figure did not meet the supermajority threshold of 361, which was calculated against a full chamber.

Opponents to Chat Control have posted resources at the Fight Chat Control website, including a breakdown of member-state and individual representative voting positions and contact information.
