It’s been a good week for Covid-19 vac­cines, and per­haps an even bet­ter one for the hack­ers try­ing to steal Covid-19 vac­cine da­ta.

In a brief note Wednes­day, the Eu­ro­pean Med­i­cines Agency an­nounced that it had been “the sub­ject of a cy­ber-at­tack.” Pfiz­er and their Ger­man biotech part­ner BioN­Tech con­firmed their da­ta had been “un­law­ful­ly ac­cessed’ as part of the breach, al­though they cau­tioned to Reuters that they did not be­lieve par­tic­i­pants’ per­son­al in­for­ma­tion had been changed and that the EMA had as­sured them the hack would not in­ter­fere with the time­line for ap­proval.

Stolen doc­u­ments could po­ten­tial­ly give use­ful in­for­ma­tion to oth­er coun­tries de­vel­op­ing a vac­cine, as well as in­for­ma­tion on oth­er com­pa­nies and sys­tems in­volved in de­vel­op­ing and dis­trib­ut­ing it.

The lat­est in­ci­dent adds to a string of vac­cine-di­rect­ed cy­ber­se­cu­ri­ty at­tacks that have re­port­ed­ly struck through­out the pan­dem­ic. News re­ports of such ef­forts have picked up in re­cent weeks.

In May, as vac­cine ef­forts were ac­cel­er­at­ing, US of­fi­cials warned Chi­nese hack­ers were tar­get­ing vac­cine re­search, prompt­ing a swift de­nial from the Chi­nese gov­ern­ment.

In Ju­ly, though, Britain’s Na­tion­al Cy­ber Se­cu­ri­ty Cen­tre re­leased a re­port ac­cus­ing Russ­ian-backed groups, in­clud­ing one known as “Cozy Bear,” of tar­get­ing phar­ma­ceu­ti­cal com­pa­nies work­ing on vac­cines. The Cen­tre said that US and Cana­di­an of­fi­cials shared their as­sess­ment, and The Tele­graph re­port­ed that the As­traZeneca-Ox­ford ef­fort had been at­tacked. Rus­sia de­nied in­volve­ment.

Then last month, Mi­crosoft said that a Russ­ian group named “Fan­cy Bear” and two North Ko­re­an groups named “Zinc” and “Ceri­um” at­tempt­ed to break in­to sys­tems at 7 phar­mas and re­searchers in 5 coun­tries. That in­clud­ed brute force ef­forts to at­tempt mil­lions of po­ten­tial pass­words and phish­ing schemes where hack­ers would pose as World Health Or­ga­ni­za­tion of­fi­cials and so­lic­it peo­ple’s pass­words.

Last week, IBM said that hack­ers backed by for­eign gov­ern­ments had turned their at­ten­tion to the com­pa­nies that main­tain the cold chain nec­es­sary to ship and store mR­NA vac­cines. Among oth­er ef­forts, ad­ver­saries posed as an ex­ec­u­tive from the ma­jor cold chain com­pa­ny Haier Med­ical and so­licit­ed user­names and pass­words. The at­tacks were glob­al, IBM said.

While the US biosimilars industry has generally been a disappointment since its inception, with FDA approving 33 biosimilars since 2015, just a fraction of those have immediately followed their approvals with launches. And more than a handful of biosimilars for two of the biggest blockbusters of all time — AbbVie’s Humira and Amgen’s Enbrel — remain approved by FDA but still have not launched because of legal settlements.

Kura Oncology is clear to resume studies for its early-stage leukemia program after the FDA lifted a clinical hold Thursday afternoon.

Regulators had placed the hold on a Phase Ib study of KO-539, an experimental oral treatment for some genetic subsets of acute myeloid leukemia last November after a patient died while taking the drug. Kura expects to begin enrolling patients again imminently, CEO Troy Wilson told Endpoints News.
