The Mozambican computer system was the victim of a cyber attack between late Sunday and most of Monday morning. About 30 government sites were taken down, allegedly by Yemeni terrorists.

Government websites, those with the extension (gov.mz) have been replaced with images usually related to the so-called "Islamic insurgency."

"Attacked by Yemeni 'hackers'" is the title, written in English, of the page with a picture of a man with a machine gun and scarf on his head that appears replicated when trying to enter different portals.

Among the hijacked sites are those of the National Institute of Disaster Management (INGD), the National Roads Administration, the Southern Regional Water Administration, and the National Institute of Land Transport (INATTER), according to Mozambique Television.

Despite this, some relevant sites in the country seem to have remained intact, such as those of the Government, the Presidency of the Republic, the Bank of Mozambique, the Ministry of Health, the Covid-19 portal, the National Statistics Institute, and the Attorney General's Office (PGR).

What information were the Yemeni "hackers" after all?

So far it seems that the hackers have managed to access information relevant to the country, as could be read in a footer message on the image that appeared on the hijacked portals.

The page replicated on all inoperable 'sites' announces in the footer that data has been extracted and will be sold at a cheap price, but without displaying evidence.

Government sites in Mozambique are under the responsibility of the National Institute of Information and Communication Technologies - which also had its site offline - and the National Institute of Electronic Government.
