To varying degrees, most techies are aware of the security vulnerabilities identified in the OWASP Top 10 (SQL Injection, trying to homebrew Identity management etc), although I still sometimes have conversations where I feel the need to get the yellow or red card out. But the bottom line is that these risks are perhaps more appreciated because it is easier to understand external entities attacking seeking direct attacks to disrupt or access information. But there are often subtler and at least more costly to repair attacks such as internal attacks and indirect attacks such as compromising software deployment mechanisms.
This, later attack Is not a new risk, as you can see from the following links, been recognised by the security community for some time (you can find academic papers going back 10+ years looking at the security risks for Yum and RPM for example).

- Consequences of Insecure Software Updates

But software is becoming ever more pervasive, we’re more aware than ever that maintaining software to the latest releases means that known vulnerabilities are closed. As a result, we have seen a proliferation in mechanisms to recognise the need to update and deploying updates. 10 years ago, updating frameworks where typically small in number and linked to vendors who could/had to invest in making the mechanisms as a secure as possible – think Microsoft, Red Hat. However we have seen this proliferate, any browser worthy of attention has automated updating let alone the wider software tools. As development has become more polyglot every language has its central repos of framework libraries (maven central, npm, chocolatey ….). Add to this the growth in multi-cloud and emphasis on micro deployments to support microservices and the deployment landscape gets larger and ever more complex and therefore vulnerable.
