This action may indicate of an IP hijack attempt of an unauthorized actor in the cloud environment, which can lead to DOS, lateral-movement or IP-takeover. An AWS Elastic IP is an allocated public and static IPv4 address that is accessible from the internet and can be associated with compute instances and network interfaces. A malicious actor can abuse the EIP transfer feature, that allows transferring EIPs between accounts, in order to take over a victim's public IP address. This IP address may be associated with critical services or sensitive network/firewall allow-lists, thus misusing it can cause severe damage in the face of Denial-Of-Service, Bypassing allow-lists and Conducting phishing attacks.
