The sorry state of skill distribution
The article discusses the vulnerabilities in skill distribution channels that allow malicious skills to infiltrate systems. Despite the introduction of skill scanners by security companies, tests reveal that these tools are ineffective at detecting threats. The rise of public marketplaces has exacerbated the issue, making it easier for harmful skills to reach unsuspecting users.
- ▪Public skill marketplaces are inundated with malicious skills that can steal credentials and exfiltrate data.
- ▪Tests conducted on various skill scanners showed that they can be easily bypassed by attackers.
- ▪The distribution channels for skills often prioritize speed over security, leading to increased risks.
