Pointing fingers at “fake vaccines”

Several threat actors leaking what they claimed to be the stolen EMA data on multiple hacker forums on December 31st.

Several sources within the cybersecurity Intelligence Community told in an interview that the leaked data archives included email screenshots, EMA referee comments, also as Word, PDF, PowerPoint documents.

Following the December attack, the agency disclosed that it launched a joint investigation together with enforcement and a number of other other relevant entities.

Pfizer and BioNTech jointly disclosed that some COVID-19 documents concerning the regulatory submission stored on EMA’s servers were accessed by the threat actors behind the cyberattack.

EMA later revealed that the investigation shows that only a limited number of documents linked to the BNT162b2 COVID-19 vaccine candidate were accessed without authorization during the incident.

EMA also discovered that the info breach was limited to one IT app, with the threat actors behind this attack primarily targeting data associated with COVID-19 vaccines and medicines.

An EMA spokesperson wasn’t immediately available for comment when contacted by an interviewer earlier today.
