Open Source and Open Doors. Bad Actors, Come On In

May 13, 2024

Open source code is awesome, because it allows developers to create projects without paying proprietary fees and it inspires innovation. Open source code, however, has problems especially when bad actors know how to exploit it. OpenSSF shares how a recent open source back door left many people vulnerable: “Open Source Security (OpenSSF) And OpenJS Foundations Issue Alert For Social Engineer Takeovers Of Open Source Projects.”

The OpenJS Foundation hosts billions of JavaScript websites. The foundation recently discovered a social engineering takeover attempt dubbed XZ Utilz backdoor, similar to another hack in the past. The OpenJS Foundation and the Open Source Security Foundation are alerting developers about the threat.

The OpenJS received a series of suspicious emails from various GitHub emails that advised project administrators to update their JavaScript. The update description was vague and wanted the administrators to allow the bad actors access to projects. The scam emails are part of the endless bag of tricks black hat hackers use to manipulate administrators, so they can access source code.

The foundations are warning administrators about the scams and sharing tips about how to recognize scams. Bad actors exploit open source developers:

“These social engineering attacks are exploiting the sense of duty that maintainers have with their project and community in order to manipulate them. Pay attention to how interactions make you feel. Interactions that create self-doubt, feelings of inadequacy, of not doing enough for the project, etc. might be part of a social engineering attack.

Social engineering attacks like the ones we have witnessed with XZ/liblzma were successfully averted by the OpenJS community. These types of attacks are difficult to detect or protect against programmatically as they prey on a violation of trust through social engineering. In the short term, clearly and transparently sharing suspicious activity like those we mentioned above will help other communities stay vigilant. Ensuring our maintainers are well supported is the primary deterrent we have against these social engineering attacks.”

These scams aren’t surprising. There needs to be more organizations like OpenJS and Open Source Security, because their intentions are to protect the common good. They’re on the side of the little person compared to politicians and corporations.
