A coordinated token farming marketing campaign continues to flood the open supply npm registry, with tens of 1000’s of contaminated packages created nearly every 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 concerning 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 menace actors are paying consideration, he predicted.
“I’m certain anyone on the market on the earth is taking a look at this massively replicating worm and questioning if they will trip 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 concerning the marketing campaign simply over a 12 months in the past, it discovered a mere 15,000 packages that appeared to return from a single individual.
With the swollen numbers reported this week, Amazon researchers wrote that it’s “one of many largest package deal flooding incidents in open supply registry historical past, and represents a defining second in provide chain security.”
This marketing campaign is simply the newest approach menace actors are profiting from security holes in various open supply repositories, which runs the danger of damaging the fame of websites 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 resolution.
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 your complete dependency ecosystem. “What started as a single compromise explodes in a number 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 business.”
This previous September, Raidman wrote concerning the compromise of the Nx construct system after menace actors pushed malicious variations of the package deal into npm. Inside hours, he wrote, builders world wide had been unknowingly pulling in code that stole SSH keys, authentication tokens, and cryptocurrency wallets.
These and newer massive scale uploads of malicious packages into open supply repositories are “just the start,” he warned, except builders and repository maintainers enhance security.
The Amazon and Sonatype reviews 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 offers open-source builders and package deal 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 may then be cashed in by means of a fund. The worm scheme is an try to make the blockchain assume apps created by the menace actors are extremely fashionable and subsequently earn a whole lot of tokens.
In the mean time, the tokens haven’t any worth. However it’s suspected that the menace 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 might 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 may encourage others to reap the benefits of different reward-based techniques 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 the usage of multi-factor authentication in case login credentials of builders are stolen, he stated, and including digital signing capabilities to uploaded code to authenticate the creator.
IT leaders ought to insist all code their agency makes use of has a software program invoice of supplies (SBOM), so security groups can see the parts. In addition they have to insist builders know the variations of the open supply code they embrace of their apps, and make sure solely authorized and secure variations are getting used and never robotically 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 have to deploy superior detection techniques to establish suspicious patterns like malicious configuration recordsdata, minimal or cloned code, predictable code naming schemes and round dependency chains.
“Equally essential,” they add, “is monitoring package deal publishing velocity, since automated instruments create at speeds no human developer may match. As well as, enhanced creator validation and accountability measures are essential for prevention. This consists of 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 observe behavioral patterns like fast account creation adopted by mass package deal publishing, that are hallmarks of automated abuse.”
CISOs discovering these packages of their environments “face an uncomfortable actuality,” the Amazon authors add: “Their present security controls had did not 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 security instruments like EDR and SCA don’t scan for malware, he warned. “The variety of people who purchase Snyk considering 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 package deal 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 robotically. MALOSS can be utilized in a CI/CD pipeline or on an area workstation.
He additionally recommends the usage of a business or open supply package deal firewall, which successfully permits a developer to solely set up authorized packages.
“The enterprise has extra choices than I believe they notice,” he advised CSO. “They simply typically don’t notice that there are instruments and options to handle this danger. Maturity is admittedly low on this area.”
