The group primarily focuses on financial theft through ransomware and banking malware, leveraging sophisticated techniques to target high-value entities ("big-game hunting"). Their goals are monetary gain and large-scale disruption.

Indrik Spider employs phishing schemes, advanced persistent threats (APTs), and credential theft to infiltrate systems. Techniques often involve the deployment of malware like Dridex and ransomware variants such as DoppelPaymer, with lateral movement strategies ensuring extensive infiltration before execution.

Their methods include initial access through phishing campaigns exploitation of unpatched vulnerabilities, and code signing to evade detection. Once inside, they exfiltrate data, encrypt systems, and execute double-extortion tactics by threatening to leak sensitive information unless the ransom is paid.
