Organizations researching the disease were warned of "likely targeting and network compromise by the People's Republic of China", a statement from the Federal Bureau of Investigation and the Cybersecurity and Infrastructure Security Agency said.
The Wall Street Journal's (WSJ) source said the joint alert will "accuse Beijing of working to steal from American institutions intellectual property and health information related to coronavirus vaccines and treatment through hacking and other illicit means and may come within days".
"The potential theft of this information jeopardizes the delivery of secure, effective and efficient treatment options", the statement read.
Chinese biotech companies reported recently that they have four different coronavirus vaccines already undergoing clinical trials, with three of them entering the second stage, with pilot production of an inactivated COVID-19 vaccine expected to begin in July.
American officials have long accused China of stealing trade secrets and valuable medical technology from USA corporations to develop their economy, allegations Beijing denies.
Earlier this week, Reuters reported that Iran-backed hackers targeted us drug maker Gilead, whose antiviral drug remdesivir is the only treatment that has so far shown to help patients suffering from COVID-19. "That will be in line with their capabilities and intent the last decade plus, and we are expecting them to continue to do so".
The US and Britain jointly announced this month that the two countries were investigating hacking incidents against pharmaceutical companies, medical groups and universities involved in research related to the coronavirus.
They also cautioned that increased media attention about virus research done by a specific organization will lead to increased "cyber activity".
More than 4.3m people around the world have been infected by Covid-19, with over 83,000 USA deaths and 4,600 deaths in China, according to Johns Hopkins University.
The FBI also said last month in a joint flash alert coordinated with CISA that phishing campaigns were targeting United States healthcare providers with COVID-19 themed lures to distribute malicious attachments to create "an initial intrusion vector to enable follow-on system exploitation, persistence, and exfiltration".
Setting obstacles for investors in the United States to enter the Chinese market in the name of so-called national security, or even politicizing their normal investment activities will only harm their own interests, Foreign Ministry spokesman Zhao Lijian said on Wednesday.
Asked about the coming report, U.S. President Donald Trump replied: "What else is new with China? Tell me. I'm not happy with China".
