A coordinated token farming marketing campaign continues to flood the open supply npm registry, with tens of hundreds 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 mentioned 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, instructed CSO that quantity has now grown to 153,000.
“It’s unlucky that the worm isn’t beneath management but,” mentioned 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 planet is taking a look at this massively replicating worm and questioning if they’ll journey 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 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 package deal 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 approach menace actors are making the most of safety holes in quite a few open supply repositories, which runs the chance 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,” mentioned 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 reveals 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 just a few 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 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 all over the world have 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 “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 offers open-source builders and package deal maintainers tokens referred to 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 to make the blockchain assume apps created by the menace actors are extremely common and due to this fact earn quite a 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 will be traded.
For now, says Sonatype’s Fox, the scheme wastes the time of npm directors, who’re making an attempt to expel over 100,000 packages. However Fox and Amazon level out the scheme may encourage others to make the most of different reward-based programs 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, mentioned Raidman of Cybeats. That features using multi-factor authentication in case login credentials of builders are stolen, he mentioned, 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 parts. Additionally they must insist builders know the variations of the open supply code they embody of their apps, and make sure solely authorized and protected variations are getting used and never routinely modified simply because a brand new model is downloaded from a repository.
Sonatype’s Fox mentioned IT leaders want to purchase instruments that may intercept and block malicious downloads from repositories. Antivirus software program is ineffective right here, he mentioned, as a result of malicious code uploaded to repositories gained’t comprise the signatures that AV instruments are alleged to detect.
In response to emailed questions, the authors of the Amazon weblog, researchers Chi Tran and Charlie Bacon, mentioned open supply repositories must deploy superior detection programs to determine suspicious patterns like malicious configuration information, 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 writer validation and accountability measures are essential for prevention. This consists of implementing stronger identification verification for brand 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’ rules the place packages from accounts linked to malicious exercise obtain heightened scrutiny. Repositories also needs to monitor 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 safety controls had did not detect a coordinated provide chain assault.”
SourceCodeRed’s McCarty mentioned 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 who purchase Snyk pondering it does that is big,” he mentioned.
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 instrument, 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 package deal firewall, which successfully permits a developer to solely set up authorized packages.
“The enterprise has extra choices than I believe they understand,” he instructed CSO. “They only typically don’t understand that there are instruments and options to handle this threat. Maturity is basically low on this area.”
