Three large-scale malware campaigns have infiltrated Docker Hub, deploying tens of millions of malicious “imageless” containers.
The info comes from JFrog’s safety analysis staff, which not too long ago revealed a regarding development inside Docker Hub.
The platform, identified for facilitating Docker picture improvement, collaboration and distribution, hosts over 12.5 million repositories. Nevertheless, in response to JFrog, roughly 25% of those repositories lack helpful performance and serve as a substitute as automobiles for spam, pirated content material promotion and malware dissemination.
In response to the report revealed at the moment, the assault on Docker Hub exploited its group options, permitting customers to publish repositories with solely documentation pages, devoid of precise container pictures. Disguised as legit content material, these documentation pages lead unsuspecting customers to phishing and malware-hosting web sites.
To determine these malicious repositories, the analysis staff analyzed the creation patterns of Docker Hub pictures over the previous 5 years. They found anomalies in repository creation, figuring out over 4 million imageless repositories, constituting 37% of all public repositories.
Additional investigation revealed three principal malware campaigns: the “Downloader” marketing campaign, which presents pirated content material and sport cheats; the “eBook Phishing” marketing campaign, which lures customers with free eBook downloads to steal bank card data; and the “Web site” marketing campaign, characterised by randomly generated repositories containing benign descriptions.
Every marketing campaign employed distinct ways to evade detection, comparable to URL shorteners and open redirect bugs. The payloads of those campaigns, predominantly Trojans, communicated with command-and-control (C2) servers to obtain extra malware and execute persistent duties on contaminated programs.

“Essentially the most regarding facet of those three campaigns is that there’s not so much that customers can do to guard themselves on the outset apart from exercising warning,” warned Andrey Polkovnichenko, safety researcher at JFrog. “We’re basically taking a look at a malware playground that, in some instances, has been three years within the making.”
These findings have vital implications, highlighting the necessity for enhanced moderation on Docker Hub and higher group involvement in detecting and mitigating malicious exercise.
“These risk actors are extremely motivated and are hiding behind the credibility of the Docker Hub identify to lure victims,” Polkovnichenko added.
“As Murphy’s Regulation suggests, if one thing could be exploited by malware builders, it inevitably can be, so we count on that these campaigns could be discovered in additional repositories than simply Docker Hub.”
