CERT-In warned that malicious actors are planning a large-scale phishing attack campaign on individuals and businesses. It is not sponsored by China.
The CYFIRMA, a cybersecurity company, and its researchers exposed that a global COVID-19 related phishing campaign is operated by Lazarus group, a known hacker group sponsored by North Korea. Therefore we can conclude that the phishing campaign was sponsored by the Lazarus group funded by North Korea, and not by Chinese hackers.
The COVID-19 pandemic has given rise to a lot of potentially dangerous misinformation. For reliable advice on COVID-19 including symptoms, prevention and available treatment, please refer to the World Health Organisation or your national healthcare authority.
