Australian Cyber Security Centre Warns of Escalating Code Repository Attacks

The Australian Signals Directorate’s Australian Cyber Security Centre (ACSC) has issued a high alert regarding increasingly complex attacks targeting online code repositories. Avocado Consulting urges Australian organizations to bolster their software supply chain security in response.
The Rising Threat to Code Repositories
The Australian Cyber Security Centre (ACSC) has warned of a important increase in attacks targeting online code repositories. These attacks leverage a variety of techniques,including social engineering,compromised credentials,stolen authentication tokens,and manipulation of software packages.The ACSC alert underscores the critical need for organizations to proactively secure their software supply chains.
Code repositories,such as github,GitLab,and Bitbucket,are central to modern software development. A prosperous breach can provide attackers with access to source code, intellectual property, and, crucially, sensitive credentials that can be used to compromise broader systems.
Attack Techniques: From Malware to “Living Off the Land”
According to dennis Baltazar, Principal Cloud and DevSecOps Solutions at Avocado Consulting, the sophistication of these attacks is evolving. Attackers are increasingly moving away from relying on bespoke malware and rather employing “living off the land” (LOTL) techniques.

What’s significant here, is not just attacker capability but attacker tradecraft. This wave of repository targeting blends social engineering living-off-the-land (LOTL) techniques – abusing legitimate tools and workflows so malicious activity looks like business as usual.
LOTL techniques involve attackers exploiting existing tools and workflows within a system, making malicious activity harder to detect. This means attackers don’t need to introduce new malware; they can leverage existing infrastructure to achieve their objectives.
The Critical Vulnerability: Secrets Sprawl
Avocado Consulting identifies “secrets sprawl” – the proliferation of sensitive details like passwords, API keys, and authentication tokens across multiple systems – as a major blind spot for organizations. this practice dramatically increases the risk of a successful attack.

The biggest blind spot we see isn’t a zero-day, it’s secrets sprawl. Keys and tokens in code or CI/CD logs turn a minor repo slip into organisation-wide compromise.
A compromised code repository containing exposed secrets can provide attackers with the keys to access critical infrastructure and data. This highlights the importance of robust secrets management practices.
Consider the following scenario: a developer accidentally commits an API key to a public repository. An attacker discovers this key and uses it to access a cloud service, potentially leading to data breaches or financial loss. This illustrates the real-world impact of secrets sprawl.
Recommendations: Immediate Actions and Long-Term Strategies
Avocado Consulting recommends that organizations take immediate steps to mitigate the risks associated with code repository attacks:
- Audit for Exposed Credentials: Conduct thorough audits to identify and address unmanaged privileged accounts and non-human identities.
- implement Robust
