Socket's research uncovers three dangerous Go modules that contain obfuscated disk-wiping malware, threatening complete data loss.

The Go ecosystem, valued for its simplicity, transparency, and flexibility, has exploded in popularity. With over 2 million modules available, developers rely heavily on public repositories like GitHub. However, this openness is precisely what attackers exploit.

No Central Gatekeeping: Developers freely source modules directly from GitHub repositories, trusting the naming conventions implicitly.
Prime Target for Typosquatting: Minimal namespace validation enables attackers to masquerade malicious modules as popular libraries.
Introduction: The Silent Threat#
In April 2025, we detected an attack involving three malicious Go modules which employ similar obfuscation techniques:

github[.]com/truthfulpharm/prototransform
github[.]com/blankloggia/go-mcp
github[.]com/steelpoor/tlsproxy
Despite appearing legitimate, these modules contained highly obfuscated code designed to fetch and execute remote payloads. Socket’s scanners flagged the suspicious behaviors, leading us to a deeper investigation.

A supply-chain attack targets Linux servers with disk-wiping malware hidden in Golang modules published on GitHub.

The campaign was detected last month and relied on three malicious Go modules that included “highly obfuscated code” for retrieving remote payloads and executing them.

Complete disk destruction
The attack appears designed specifically for Linux-based servers and developer environments, as the destructive payload - a Bash script named done.sh, runs a ‘dd’ command for the file-wiping activity.

Furthermore, the payload verifies that it runs in a Linux environment (runtime.GOOS == "linux") before trying to execute.

An analysis from supply-chain security company Socket shows that the command overwrites with zeroes every byte of data, leading to irreversible data loss and system failure.

The target is the primary storage volume, /dev/sda, that holds critical system data, user files, databases, and configurations.

“By populating the entire disk with zeros, the script completely destroys the file system structure, operating system, and all user data, rendering the system unbootable and unrecoverable” - Socket

The researchers discovered the attack in April and identified three Go modules on GitHub, that have since been removed from the platform:

github[.]com/truthfulpharm/prototransform
github[.]com/blankloggia/go-mcp
github[.]com/steelpoor/tlsproxy

On April 26, an unauthorized user exploited a vulnerability with a GitHub workflow to gain unauthorized access to tokens, all of which have now been invalidated. At this time, our investigation has found no evidence of code modifications, unauthorized access to production systems, exposure of customer data, or access to personal information.

The Sysdig Threat Research Team (TRT) has discovered CVE-2025-32955, a now-patched vulnerability in Harden-Runner, one of the most popular GitHub Action CI/CD security tools. Exploiting this vulnerability allows an attacker to bypass Harden-Runner’s disable-sudo security mechanism, effectively evading detection within the continuous integration/continuous delivery (CI/CD) pipeline under certain conditions. To mitigate this risk, users are strongly advised to update to the latest version.

The CVE has been assigned a CVSS v3.1 base score of 6.0.

A clever threat campaign is abusing GitHub repositories to distribute malware targeting users who frequent an open source project repository or are subscribed to email notifications from it. A malicious GitHub user opens a new

• Check Point Research identified a network of GitHub accounts (Stargazers Ghost Network) that distribute malware or malicious links via phishing repositories. The network consists of multiple accounts that distribute malicious links and malware and perform other actions such as starring, forking, and subscribing to malicious repositories to make them appear legitimate.
• This network is a highly sophisticated operation that acts as a Distribution as a Service (DaaS). It allows threat actors to share malicious links or malware for distribution through highly victim-oriented phishing repositories.
• Check Point Research is tracking the threat group behind this service as Stargazer Goblin. The group provides, operates, and maintains the Stargazers Ghost Network and distributes malware and links via their GitHub Ghost accounts.
• The network distributed all sorts of malware families, including Atlantida Stealer, Rhadamanthys, RisePro, Lumma Stealer, and RedLine.
• Our latest calculations suggest that more than 3,000 active Ghost accounts are part of the network. Based on core GitHub Ghost accounts, we believe that the network began development or testing on a smaller scale for the first time around August 2022.
• Check Point Research discovered an advertiser in Dark-Web forums that provides the exact GitHub operation. The first advertisement was published on July 8, 2023, from an account created the previous day.
• Based on the monitored campaigns from mid-May to mid-June 2024, we estimate that Stargazer Goblin earned approximately $8,000. However, we believe that this amount is only a small fraction of what the actor made during that period. The total amount during the operations’ lifespan is estimated to be approximately $100,000.
• Stargazers Ghost Network appears to be only one part of the grand picture, with other Ghost accounts operating on different platforms, constructing an even bigger Distribution as a Service universe.

The New York Times notified an undisclosed number of contributors that some of their sensitive personal information was stolen and leaked after its GitHub repositories were breached in January 2024.

A "multi-faceted campaign" has been observed abusing legitimate services like GitHub and FileZilla to deliver an array of stealer malware and banking trojans such as Atomic (aka AMOS), Vidar, Lumma (aka LummaC2), and Octo by impersonating credible software like 1Password, Bartender 5, and Pixelmator Pro.
