THE World Health Organisation (WHO) has seen a dramatic five-fold increase in the number of cyberattacks and email scams since the pandemic was declared a major emergency at the end of January.

Around 450 active WHO email addresses and passwords were leaked online this week, said the organisation, along with thousands belonging to people working on a response to Covid-19.

WHO said the leaked credentials did not put systems at risk because the data were not current, but it did impact one of its older systems. The agency is now migrating the affected systems to a more secure one.

Scammers impersonating WHO in emails have increased their attacks on the general public, it said, trying to channel donations to a fictitious fund.

Its chief information officer, Bernardo Mariano, said: “Ensuring the security of health information for member states and the privacy of users interacting with us is a priority for WHO at all times, but also particularly during the Covid-19 pandemic. We are grateful for the alerts we receive from member states and the private sector. We are all in this fight together.”

Earlier this month, hackers tried unsuccessfully to break into the agency’s computers, an attempt first flagged to Reuters by Alexander Urbelis, a cybersecurity expert and lawyer with a New York-practice that tracks suspicious internet domain registration activity.

Urbelis said he noticed the activity around March 13, when a group of hackers he’d been following activated a malicious site mimicking the WHO’s internal email system.

“I realised quite quickly that this was a live attack on the World Health Organization in the midst of a pandemic,” he said.

Urbelis said he did not know who was responsible, but two other sources said they suspected an advanced group of hackers known as DarkHotel, which has been conducting cyber-espionage operations since at least 2007.

WHO chief information security officer, Flavio Aggio, confirmed that the site had been used in an attempt to steal passwords from multiple agency staff. “There has been a big increase in targeting of the WHO and other cybersecurity incidents,” he said. “There are no hard numbers, but such compromise attempts against us and the use of WHO impersonations to target others have more than doubled.”
