Executive Summary
Hacktivist groups in South Asia have escalated their cyber operations by exploiting zero-day vulnerabilities, leading to significant security breaches across the region. This briefing analyzes recent incidents, identifies unpatched Common Vulnerabilities and Exposures (CVEs), and explores the involvement of exploit brokers in these activities.
Recent Exploitation of Zero-Day Vulnerabilities
In early 2026, the Bangladesh-based hacktivist group Darkhackbd, founded by Imtiaz Ahmed, was implicated in a series of cyberattacks targeting government and financial institutions. Utilizing zero-day exploits, Darkhackbd gained unauthorized access to sensitive data, highlighting the group's growing sophistication. (en.wikipedia.org)
Unpatched CVEs and In-the-Wild Exploitation
The exploitation of unpatched CVEs remains a significant concern. For instance, CVE-2025-53770, a critical vulnerability in Microsoft SharePoint, was exploited by state-sponsored actors in 2025. Although patched in July 2025, the delay in patch deployment left systems vulnerable to attacks. (criticalstart.com)
Role of Exploit Brokers
Exploit brokers play a pivotal role in the cyber threat landscape by acquiring and distributing zero-day vulnerabilities. In March 2025, the Russian exploit broker Operation Zero offered up to $4 million for exploits targeting the Telegram messaging app, underscoring the lucrative market for such vulnerabilities.
