The attacks were carried out as part of a broader malicious campaign called Ghostwriter.
The emails of about a dozen members of the Polish parliament have been hacked, which has become one of the largest cyberattacks in the country in the past few years.
News of the hack emerged two weeks after members of the Polish government were hit by a cyberattack that affected the emails of more than a hundred current and past parliamentarians. The incident affected representatives of almost all opposition factions in parliament, writes Reuters. All victims were notified of the incident and received training on cyber security.
In particular, cybercriminals allegedly managed to hack into the e-mail of the chief assistant to the Prime Minister Michal Dvorczyk. The hack sparked a series of leaks that drew opposition criticism to officials for using personal mail to exchange confidential documents. The names of the affected parliamentarians were not disclosed.
According to Polish counterintelligence, the attacks were carried out by the hacker group UNC1151 as part of a broader malicious campaign dubbed Ghostwriter. The campaign has been going on for several months now and is aimed at politicians in Poland and neighboring countries.
