Threat Group

TALONITE

Spearphishing with malicious documents or executables for initial access compromise.

Threat Group: Talonite
THREAT DESCRIPTION
Dragos began tracking the TALONITE activity group in July 2019, with operations focusing on initial access compromises in the United States (U.S.) electric sector. The group uses phishing techniques with either malicious documents or executables. TALONITE uses two custom malware families that both feature multiple components known as LookBack and FlowCloud.

TALONITE focuses on subverting and taking advantage of trust with phishing lures focusing on engineering-specific themes and concepts, malware using legitimate binaries maliciously or modifying such binaries to include additional functionality, and a combination of owned and compromised network infrastructure.

TALONITE activity is difficult to track and contain given the group’s propensity to blend techniques and tactics to ensure a successful intrusion. Although there is behavioral overlap between TALONITE and the Chinese state-sponsored group, APT10, Dragos cannot definitively link these two groups.
