Threat intelligence agency Recorded Future has warned that menace actors are more and more utilizing GitHub providers to launch covert cyber-attacks, and urged IT groups to take motion.
Its new report Flying Under the Radar: Abusing GitHub for Malicious Infrastructure revealed the preferred GitHub providers for menace actors.
An evaluation of menace intelligence samples between March and November 2023 confirmed GitHub Raw (40%), GitHub Objects (35%) and GitHub Pages (14%) have been most frequently utilized in assaults.
GitHub is utilized by virtually 100 million builders and thus represents a probably large-scale menace if the platform may be efficiently abused.

Recorded Future claimed that menace actors use it to mix in with benign community visitors, thus maintaining malicious exercise hidden. It added that GitHub providers often stay unblocked in organizations however profit from excessive uptime, minimal new account vetting and restricted detection potentialities for service suppliers.
That makes it a preferred, low-cost and extremely efficient platform for command-and-control (C&C) infrastructure, silent supply of malware payloads and exfiltration of knowledge, the report claimed.
Organizations want to contemplate GitHub of their menace modeling, Recorded Future argued.
“In the close to time period, defenders ought to pursue a service-based technique by flagging and even blocking particular GitHub providers that aren’t usually used of their atmosphere and are identified for use maliciously,” the report famous.
“This ought to be paired with a context-based technique based mostly on the precept that solely particular components of a company atmosphere necessitate interplay with specific GitHub providers. In the long term, organizations ought to allocate assets to higher perceive how GitHub and different code repositories are abused.”
It concluded with eight suggestions:
- Enhance visibility into GitHub with granular monitoring of all net and cloud visitors and context-aware insurance policies enforced on the occasion stage
- Maintain an up-to-date asset stock itemizing all customers licensed to entry GitHub
- Adapt detection methods to align with the group’s specific atmosphere
- Deploy adaptive safety insurance policies, probably alongside software allow-listing
- Protect GitHub accounts to stop hijacking by menace actors to steal code or use as C&C infrastructure
- Continually assess the effectiveness of menace detection capabilities by integrating eventualities of GitHub abuse into assault simulations
- Collaborate with GitHub to assist it combat again towards identified malicious exercise on the platform
- Perform proactive menace looking to combat unknown cases of GitHub abuse
