SideCopy Broadens India Targeting to Academia With ReverseRAT Spear-Phishing

SideCopy APT group targets Indian academia with ReverseRAT via spear-phishing.

The Pakistan-based APT group SideCopy, also known as TAG-140, has expanded its targeting in India to include academic institutions, moving beyond its historical focus on government entities. The group employs spear-phishing campaigns that abuse mshta.exe to deliver its ReverseRAT malware, which is capable of extensive data exfiltration and remote control.

The lesson from this incident

Full lesson

The Pakistan-linked APT group SideCopy has expanded its spear-phishing campaigns beyond Indian government targets to now include academic institutions, exploiting the often-weaker security postures found in educational environments. The attacks abuse mshta.exe, a legitimate Windows binary, to execute malicious HTA files delivered via convincing phishing lures — a technique known as 'living off the land' that bypasses many traditional defenses. Once ReverseRAT is deployed, attackers gain persistent remote access and can exfiltrate sensitive research, credentials, and institutional data. This expansion highlights how APT groups deliberately pivot to softer targets within a nation's critical ecosystem when primary targets harden their defenses.
