IMT Hacktivist Group Targets Global Schools, Defaces Sanjivani India and Peruvian Institute

The IMT hacktivist group has claimed responsibility for a string of coordinated cyberattacks targeting educational institutions across multiple countries. In their latest campaign, IMT defaced websites belonging to the Sanjivani Group of Institute in India and the Daniel Villar Public Institute of T.H.E. in Peru, marking both with their digital “stamp” as proof of intrusion. These incidents highlight growing vulnerabilities in the education sector, where outdated systems and limited resources leave schools exposed to hacktivist and ransomware activity.

Background

IMT, a relatively new hacktivist collective, operates with a public “trophy” model similar to groups like TeamInsane and GhostSec. Rather than selling stolen data for profit, IMT posts defacements and screenshots of breached systems as evidence of its reach and technical ability. The group often targets government and educational platforms in developing regions, exploiting poor patch management, unprotected admin panels, and insecure web servers.

In their most recent post, IMT shared a live link to the Peruvian institute’s official site (iestpdv.edu.pe), showing full control of the domain and website content. The same message referenced the Sanjivani Institute in India, indicating that multiple global targets were compromised in a short timeframe. The pattern mirrors the behavior of hacktivist movements that seek attention through public announcements, often preceding deeper data leaks.

Key Cybersecurity Insights

This incident is not a simple website defacement. It represents a full system compromise, as attackers must obtain administrative or root access to alter web content at the core level. The implications extend far beyond the surface of the hacked pages.

Confirmed Defacement Equals Confirmed Compromise

To “stamp” a website, IMT must already control its backend infrastructure. This means the group can exfiltrate sensitive databases containing student and faculty data, emails, phone numbers, ID cards, and even research records. The defacement itself is merely the visible symptom of a far more serious security breach.

Hacktivism as Propaganda

Unlike financially motivated cybercriminals, hacktivists such as the IMT hacktivist group act for reputation, ideology, or chaos. By targeting schools, IMT achieves visibility while facing minimal resistance. Educational institutions often lack mature security teams or dedicated cybersecurity budgets, making them easy and high-impact targets for hacktivists seeking attention.

Exploitation of Unpatched Systems

Analysts suggest IMT likely exploited known vulnerabilities in outdated Moodle, WordPress, or Joomla platforms. Unsecured login panels, SQL injection flaws, and remote file upload weaknesses are the most common entry points. Once inside, attackers can upload web shells, create hidden admin accounts, and maintain persistent access for future data leaks or ransomware deployment.

Potential Impact on Victims

The exposure of these systems poses several risks for the affected schools:

• Leakage of student and staff personally identifiable information (PII).
• Exposure of sensitive academic data and research materials.
• Identity theft or targeted phishing attacks using stolen credentials.
• Damage to reputation and trust among students, parents, and donors.
• Legal and regulatory penalties under data protection laws such as India’s DPDP Act (2023) and Peru’s Law No. 29733.

Global Education Sector Threat Landscape

Schools, universities, and public institutes have become prime targets for hacktivists and ransomware groups worldwide. According to recent security reports, the education sector saw a 30% increase in cyberattacks in 2025, primarily driven by poorly secured online portals and remote learning systems. Small and mid-sized schools are especially vulnerable due to outdated software and weak authentication practices.

Mitigation Strategies

These incidents serve as a warning for all educational institutions to adopt proactive cybersecurity measures. The following steps can help reduce the risk of IMT-style attacks:

For Breached Institutions

• Immediate Isolation: Disconnect compromised systems from the internet. Attackers may still have live access.
• Incident Response Activation: Engage a certified DFIR (Digital Forensics and Incident Response) team to locate backdoors and assess damage.
• Credential Reset: Force password resets for all users and implement multi-factor authentication (MFA) for administrative access.
• Patch and Rebuild: Apply all available security updates, remove unused modules, and rebuild affected systems from clean backups.
• Regulatory Compliance: Report the breach to relevant authorities such as CERT-In (India) or Peru’s data protection agency, as required by law.
• Transparency and Communication: Notify all users of potential data exposure and advise them to watch for phishing or social engineering attempts.

For All Schools and Universities

• Secure CMS Platforms: Regularly update Moodle, WordPress, Joomla, and other content management systems.
• Deploy Web Application Firewalls (WAFs): Filter malicious traffic and prevent SQL injection and file upload exploits.
• Segment Networks: Separate student portals from administrative databases to reduce lateral movement risk.
• Backup and Recovery: Maintain encrypted, offline backups and routinely test recovery procedures.
• Conduct Regular Penetration Tests: Identify vulnerabilities before threat actors do.
• Educate Faculty and Students: Train users to recognize phishing emails, suspicious login prompts, and fake “security update” requests.
• Monitor Threat Channels: Track dark web mentions and Telegram groups for signs of your institution’s data being leaked.

Practical Advice for Faculty and Students

• Change all passwords immediately for school accounts, email, and learning portals.
• Enable MFA wherever possible.
• Be skeptical of messages claiming to be from school IT staff or administrators asking for login details.
• Scan personal devices with trusted security software like Malwarebytes to ensure no malware has been installed through compromised school systems.

The IMT hacktivist group’s coordinated campaign underscores how vulnerable the education sector remains to organized cyberattacks. What began as digital vandalism now represents a growing wave of politically or reputationally motivated cybercrime. The defacements in India and Peru are warning signs that schools worldwide must modernize their cybersecurity strategies, secure their online portals, and prepare for an era where hacktivists can strike from anywhere, at any time.
