Email accounts belonging to the German Greens party, a member of the country's ruling coalition, have been compromised in a cybersecurity incident, Der Spiegel reported.

According to the news outlet, the attackers gained access to the email accounts previously used by foreign minister Annalena Baerbock and economy minister Robert Habeck, as well as another 12 accounts, including those belonging to current party co-chiefs Ricarda Lang and Omid Nouripour. The Greens officials said that some of the emails were forwarded to an external server. The attack also affected the party's intranet IT system "Grüne Netz" where it exchanges confidential information.

According to officials, the attack took place on May 30. Currently, it’s not clear who may have been behind the breach, or for how long the attackers had access to the party’s network. The party said that Baerbock and Habeck hadn't actively used their party accounts since January, 2022 and that network logs showed no increase in traffic volumes that could indicate large amounts of data had been stolen.

The Green party informed relevant authorities of the incident and filed a legal complaint on May 30.
