Security experts at Alphabet Inc's Google sent 1,755 warnings in April to users whose accounts were targets of government-backed attackers, following a resurgence in hacking and phishing attempts related to the coronavirus outbreak.
Google said on Wednesday its Threat Analysis Group saw new activity from "hack-for-hire" firms, many based in India, that have been creating Gmail accounts spoofing the World Health Organization (WHO).
These accounts largely targeted business leaders in financial services, consulting and healthcare corporations in numerous countries including the United States, Slovenia, Canada, India, Bahrain, Cyprus and UK, the company said in a blog post.
Google said it continued to see attacks from hackers on medical and healthcare professionals, including WHO employees.
WHO and other organizations, at the center of a global effort to contain the coronavirus, have come under a sustained digital bombardment by hackers seeking information about the outbreak.
Frequently Asked Questions
A vaccine works by mimicking a natural infection. A vaccine not only induces immune response to protect people from any future COVID-19 infection, but also helps quickly build herd immunity to put an end to the pandemic. Herd immunity occurs when a sufficient percentage of a population becomes immune to a disease, making the spread of disease from person to person unlikely. The good news is that SARS-CoV-2 virus has been fairly stable, which increases the viability of a vaccine.
There are broadly four types of vaccine — one, a vaccine based on the whole virus (this could be either inactivated, or an attenuated [weakened] virus vaccine); two, a non-replicating viral vector vaccine that uses a benign virus as vector that carries the antigen of SARS-CoV; three, nucleic-acid vaccines that have genetic material like DNA and RNA of antigens like spike protein given to a person, helping human cells decode genetic material and produce the vaccine; and four, protein subunit vaccine wherein the recombinant proteins of SARS-COV-2 along with an adjuvant (booster) is given as a vaccine.
Vaccine development is a long, complex process. Unlike drugs that are given to people with a diseased, vaccines are given to healthy people and also vulnerable sections such as children, pregnant women and the elderly. So rigorous tests are compulsory. History says that the fastest time it took to develop a vaccine is five years, but it usually takes double or sometimes triple that time.
