State-Sponsored Zero-Day Exploitation in South Asia: A Rising Threat

In recent years, the exploitation of zero-day vulnerabilities by state-sponsored actors in South Asia has escalated, posing significant threats to the region's cybersecurity landscape. Zero-day vulnerabilities are previously unknown flaws in software or hardware that attackers can exploit before developers release patches, often leading to severe security breaches.

Current Threat Landscape

In 2025, Google’s Threat Intelligence Group reported 90 zero-day vulnerabilities exploited in the wild, with nearly half targeting enterprise-grade technologies. This marks an all-time high, indicating a strategic shift by threat actors towards critical infrastructure. (cybersecuritydive.com)

Attribution to State-Sponsored Actors

Chinese state-sponsored groups have been particularly active in exploiting zero-day vulnerabilities. In 2023, these groups were responsible for 12 zero-day exploits, up from seven in 2022.

In 2022, DriftingCloud exploited CVE-2022-1040, an authentication bypass vulnerability, to infiltrate organizations in Afghanistan, Bhutan, India, Nepal, Pakistan, and Sri Lanka. (securityweek.com)

Exploitation Techniques and Tools

State-sponsored actors employ sophisticated techniques to weaponize zero-day vulnerabilities. For instance, DriftingCloud utilized the Behinder web shell to establish persistent access within compromised networks. Additionally, the group has deployed malware such as PupyRAT, Pantegana, and Sliver to further infiltrate and control targeted systems. (thecyberpost.com)

Exploit Broker Transactions

The market for zero-day vulnerabilities has seen significant activity, with exploit brokers facilitating transactions between vulnerability discoverers and buyers, including state-sponsored actors. These brokers often operate in the gray market, selling exploits to the highest bidder, which can include government agencies. The proliferation of exploit-as-a-service models has made zero-day vulnerabilities more accessible to a broader range of threat actors, increasing the frequency and sophistication of attacks.

Implications for South Asia

The targeted exploitation of zero-day vulnerabilities by state-sponsored actors in South Asia underscores the need for enhanced cybersecurity measures. Organizations must prioritize timely patching of vulnerabilities, implement robust intrusion detection systems, and conduct regular security audits to mitigate the risks associated with zero-day exploits. Collaboration between governments, private sector entities, and international partners is crucial to strengthen the region's cybersecurity posture and respond effectively to these evolving threats.

In conclusion, the increasing use of zero-day vulnerabilities by state-sponsored actors in South Asia presents a high-level threat that demands immediate and sustained attention. Proactive measures and collaborative efforts are essential to safeguard critical infrastructure and maintain the integrity of digital ecosystems in the region.
