Meta outlined these cybersecurity threats in a quarterly report released Thursday.
The Russia-Ukraine war has posed challenges for social media companies.

The actors had previously posted content that accused Poland of mistreating migrants from the Middle East.
On March 14, they created a Facebook event in Warsaw calling for a protest against the Polish government.

Meta said these fake reports increased right before Russia’s invasion of Ukraine.
The people behind the false reports coordinated this effort in a cooking-themed Facebook Group likely to evade detection.
Meta said the Facebook Group had 50 members when it was taken down.
