Fileless attacks surge as cybercriminals evade cloud security defenses

The number of fileless or memory-based attacks that exploit existing software, applications, and protocols have surged 1,400% in the last year. That’s according to Aqua Security’s 2023 Cloud Native Threat Report, which summarizes research and observations of threat actors’ changing tactics, techniques, and procedures (TTPs), along with outlining strategies for protecting cloud environments.

Based on analysis by Aqua Nautilus researchers of 700,000 real-world attacks, the report covers three key areas: software supply chain, risk posture (including vulnerabilities and misconfigurations), and runtime protection. Among key findings is that threat actors are heavily investing resources to conceal campaigns and avoid detection to establish a stronger foothold in compromised systems. Meanwhile, various areas in the cloud software supply chain remain vulnerable to compromise and pose significant threats to organizations, the report stated.
