A coordinated token farming marketing campaign continues to flood the open supply npm registry, with tens of 1000’s of contaminated packages created nearly day by day to steal tokens from unsuspecting builders utilizing the Tea Protocol to reward coding work.
On Thursday, researchers at Amazon stated there have been over 150,000 packages within the marketing campaign. However in an interview on Friday, an government at software program provide chain administration supplier Sonatype, which wrote in regards to the marketing campaign in April 2024, advised CSO that quantity has now grown to 153,000.
“It’s unlucky that the worm isn’t underneath management but,” stated Sonatype CTO Brian Fox.
And whereas this payload merely steals tokens, different risk actors are paying consideration, he predicted.
“I’m positive someone on the market on this planet is this massively replicating worm and questioning if they’ll experience that, not simply to get the Tea tokens however to place some precise malware in there, as a result of if it’s replicating that quick, why wouldn’t you?”
When Sonatype wrote in regards to the marketing campaign simply over a yr in the past, it discovered a mere 15,000 packages that appeared to return from a single particular person.
With the swollen numbers reported this week, Amazon researchers wrote that it’s “one of many largest bundle flooding incidents in open supply registry historical past, and represents a defining second in provide chain safety.”
This marketing campaign is simply the most recent means risk actors are profiting from safety holes in numerous open supply repositories, which runs the danger of damaging the popularity of web sites like npm, PyPI and others.

“The malware infestation in open-source repositories is a full-blown disaster, uncontrolled and dangerously eroding belief within the open-source upstream provide chain,” stated Dmitry Raidman, CTO of Cybeats, which makes a software program invoice of supplies answer.
As proof, he pointed to the Shai‑Hulud worm’s fast exploitation of the npm ecosystem, which exhibits how shortly attackers can hijack developer tokens, corrupt packages, and propagate laterally throughout all the dependency ecosystem. “What started as a single compromise explodes in a couple of hours, leaving the entire ecosystem and each downstream undertaking within the trade in danger in a matter of days, no matter whether or not it’s open supply or industrial.”
This previous September, Raidman wrote in regards to the compromise of the Nx construct system after risk actors pushed malicious variations of the bundle into npm. Inside hours, he wrote, builders around the globe had been unknowingly pulling in code that stole SSH keys, authentication tokens, and cryptocurrency wallets.
These and more moderen massive scale uploads of malicious packages into open supply repositories are “only the start,” he warned, until builders and repository maintainers enhance safety.
The Amazon and Sonatype stories aren’t the primary to detect this marketing campaign. Australian researcher Paul McCarty of SourceCodeRed confirmed to us that is the worm he dubbed ‘IndonesianFoods’ in a weblog this week.
The Tea Protocol
The Tea Protocol is a blockchain-based platform that provides open-source builders and bundle maintainers tokens known as Tea as rewards for his or her software program work. These tokens are additionally supposed to assist safe the software program provide chain and allow decentralized governance throughout the community, say its creators on their web site.
Builders put Tea code that hyperlinks to the blockchain of their apps; the extra an app is downloaded, the extra Tea tokens they get, which might then be cashed in by means of a fund. The worm scheme is an try and make the blockchain suppose apps created by the risk actors are extremely in style and subsequently earn lots of tokens.
In the meanwhile, the tokens haven’t any worth. However it’s suspected that the risk actors are positioning themselves to obtain actual cryptocurrency tokens when the Tea Protocol launches its Mainnet, the place Tea tokens could have precise financial worth and will be traded.
For now, says Sonatype’s Fox, the scheme wastes the time of npm directors, who’re attempting to expel over 100,000 packages. However Fox and Amazon level out the scheme might encourage others to benefit from different reward-based methods for monetary acquire, or to ship malware.
What IT leaders and builders ought to do
To decrease the chances of abuse, open supply repositories ought to tighten their entry management, limiting the variety of customers who can add code, stated Raidman of Cybeats. That features using multi-factor authentication in case login credentials of builders are stolen, he stated, and including digital signing capabilities to uploaded code to authenticate the writer.
IT leaders ought to insist all code their agency makes use of has a software program invoice of supplies (SBOM), so safety groups can see the elements. In addition they must insist builders know the variations of the open supply code they embody of their apps, and make sure solely accepted and protected variations are getting used and never routinely modified simply because a brand new model is downloaded from a repository.
Sonatype’s Fox stated IT leaders want to purchase instruments that may intercept and block malicious downloads from repositories. Antivirus software program is ineffective right here, he stated, as a result of malicious code uploaded to repositories received’t comprise the signatures that AV instruments are speculated to detect.
In response to emailed questions, the authors of the Amazon weblog, researchers Chi Tran and Charlie Bacon, stated open supply repositories must deploy superior detection methods to determine suspicious patterns like malicious configuration recordsdata, minimal or cloned code, predictable code naming schemes and round dependency chains.
“Equally vital,” they add, “is monitoring bundle publishing velocity, since automated instruments create at speeds no human developer might match. As well as, enhanced writer validation and accountability measures are essential for prevention. This contains implementing stronger identification verification for brand spanking new accounts, monitoring for coordinated publishing exercise throughout a number of developer accounts, as seen on this marketing campaign, and making use of ‘guilt by affiliation’ ideas the place packages from accounts linked to malicious exercise obtain heightened scrutiny. Repositories must also monitor behavioral patterns like fast account creation adopted by mass bundle publishing, that are hallmarks of automated abuse.”
CISOs discovering these packages of their environments “face an uncomfortable actuality,” the Amazon authors add: “Their present safety controls had didn’t detect a coordinated provide chain assault.”
SourceCodeRed’s McCarty stated IT leaders want to guard builders’ laptops, in addition to their automated steady integration and supply pipelines (CI/CD). Conventional safety instruments like EDR and SCA don’t scan for malware, he warned. “The variety of those that purchase Snyk pondering it does that is large,” he stated.
McCarty has created two open supply malware scanning instruments. One, opensourcemalware.com, is an open database of malicious content material like npm packages. It may be checked to see if a bundle getting used is malicious. The second is the automated open-source MALOSS software, which is successfully a scanner that checks opensourcemalware.com and different sources routinely. MALOSS can be utilized in a CI/CD pipeline or on a neighborhood workstation.
He additionally recommends using a industrial or open supply bundle firewall, which successfully permits a developer to solely set up accepted packages.
“The enterprise has extra choices than I feel they understand,” he advised CSO. “They only usually don’t understand that there are instruments and options to handle this danger. Maturity is basically low on this area.”
