Rewterz Threat Alert – APT Group Lazarus – IOCs
June 22, 2020Rewterz Threat Alert – Formbook Malware
June 22, 2020
Severity
High
Analysis Summary
Threat actors are accessing organisations’ networks through remote access systems such as remote desktop protocol (RDP) and virtual private networks (VPN), as a way to create ransomware attack opportunities. They are gaining access through weak passwords, organisations not using multi-factor authentication as an extra layer of security, or a remote access system that isn’t patched. Once an attacker gains a foothold through the remote access system, they then use tools such as mimikatz, psexec, and Cobalt Strike to elevate privileges, move laterally across a network, and establish persistence on the network. The attacker can identify the need of information and extract the desired information and encrypt files.
Impact
- Gain access in the network
- Lateral movement across the network.
- Exposure of sensitive information
- File encryption
