SK Shields Releases Shadow IT Breach Response Guide

SK Shields published a guide titled "Analysis and Response Guide for Breaches Targeting Shadow IT in the Era of AI-Automated Attacks" on the 8th, according to Daily Secu. The guide examines how AI-based attack tools operate and the actual intrusion paths used in a recent financial-sector breach.

The analysis concluded that the incident was not a case of AI creating new attack techniques, but rather AI automating and scaling up existing attack processes. Attackers first targeted externally exposed management blind spots, including loan recruiter systems, employee support services and sales support platforms, before moving toward core financial transaction systems.

The AI-based penetration testing tool ARTEX was suggested as possibly having been used in the attack. EQST analyzed ARTEX as an open-source autonomous platform that selects its own next targets and expands attack paths based on previous results. Attackers used the tool to rapidly scan internet-exposed services and APIs of multiple financial companies through rented servers in several countries.

Proposed API security framework

SK Shields proposed a three-stage API security framework covering identification, API monitoring, and detection and response. The company said API security requires zero-trust-based integrated control across users, devices, networks, applications, data and visibility.

Kim Byeong-mu, head of SK Shields' Cyber Business Division, said companies must secure visibility of their assets and strengthen control of externally exposed areas including APIs. SK Shields provides integrated security services including ASM, API Security, MXDR and threat hunting.

The 2026 AI Security Conference (AIS 2026) will be held on November 3, 2026 from 09:00 to 17:00 at the Korea Science and Technology Center International Conference Hall, hosted by Daily Secu.
