Thanks for the reply Ax! I was familiar with Nexus Lifecycle, but Lift and Nexus Firewall are new to me. Will definitely check them out.

What are your thoughts on risks in this space? As a member of an org that thinks about these problems a lot, I’d love to hear about any novel attacks or mitigations you and your team have eyes on.

You're welcome! If you look at "A Timeline of SSC Attacks" compiled and periodically updated by us, the trend is getting worse than better. To be blunt, the increased volume of these unwanted packages (whether research PoCs or malicious) in recent weeks can be and has been infuriating even for us to keep up with.

Whereas, previously only typosquatting or malware published to OSS repos might have been the primary concern, the recurring incidents today have diversified in both their type and quantity.

We now have to dedicate more time and resources to analyzing malicious packages that we'd have otherwise spent on hunting for zero-days or vulnerability research activities. These packages keep multiplying and it's become a whack-a-mole situation: every other day we report malware to the OSS repos, these get taken down, and the threat actor repeats the attack with slight variations a few days later. Additionally, copycat attacks follow, further increasing the number of malware incidents.

For example, other than typosquatting attacks, between last year and now we saw attackers hijacking legitimate libraries (ua-parser-js, coa, rc) or publishing tens of thousands of dependency confusion packages (A dependency confusion attempt against VMware VSphere SDK devs was just caught by us, along with 1000+ packages targeting Azure developers caught between March & April - our blog posts will explain it all. We've thus far flagged well over 65,000 suspicious packages including malware, dependency confusion attacks, typosquats, PoC tests, etc.).

In 2022, we are met with self-sabotage and protestware incidents that are on the rise: colors/faker, node-ipc, event-source-polyfill, styled-components, es5-ext, ... These have further complicated matters, and pushed us to fine-tune our algorithms. We can now no longer trust the original developer of a library either, as they are free to change their mind on a whim (they always were).

As pioneers of a proactive solution behind dependency confusion attacks and a company that's been consistently leading OSS malware discoveries every week, I'm obviously biased but I'll say whatever solution you implement, make sure to have something in place to protect your dependencies, components, and supply chain against these novel attacks. Vulnerabilities like Log4Shell or Spring4Shell, as serious as they are, are just the tip of the iceberg when you look at the entire OSS threat landscape that's evolving.

You raise a very good point about self-sabotage and protestware. I'm reminded of the left-pad debacle from some years back that fell in the former category.

Protest via libraries is new and interesting, but I suspect boils down to a matter of acceptable licensing, liability, and guarantees.

While well intentioned, I have some anxiety that protests through dependencies that operate in production environments could cool adoption of open source projects. The solve for this will likely be more attention paid to governance of open source components--which is something I already encourage.

What trends are you folks seeing with protestware? There is a real need to spread these messages, but I don't see many consumers of said projects being receptive to their platforms assisting without consent.

Very true, the left-pad incident from 2016 may have seemed like a one off occurrence but we see protestware revived this year.

1. colors/faker followed the Log4j debacle and was more about corporations using open source heavily but not giving back enough to support the developers so the dev threw in the towel. Applications using 'colors' began freezing (entered a DoS condition) due to an infinite loop introduced by the developer in the code.

2. But with node-ipc, the self-sabotage turned destructive with the package actively deleting files on detecting a Russian/Belarusian host IP

3. event-source-polyfill, styled-components, etc. have adopted more a more "peaceful protest" approach by expressing the maintainer's views condemning the Russian war, but without engaging in outright destructive activity.

Thus far the trends have been about open source and the ongoing war.

But developers have discovered a new avenue of their creative expression (open source) which no longer limits them to simply coding the intended application functionality. And so, the questions that arise are, what will the next protest be about and if we are prepared for it?
