A group of hackers called Mysterious Team made multiple Senegalese government websites go off-line on Friday night by hitting them with denial-of-service (DDoS) attacks, a government spokesperson said.
The group claimed responsibility for the attacks in a series of Twitter posts using the hashtag #FreeSenegal used by campaigners alleging political repression in Senegal.
The attacks come at a time of heightened political tensions in Senegal which is widely considered to be one of West Africa’ most stable democracies.
In a statement early on Saturday, government spokesperson Abdou Karim Fofana said all efforts were being made to bring the sites back online.
As of Saturday afternoon, the presidency’s site was online but other official websites still appeared to be off-line, including the government and finance ministry sites.
DDoS attacks work by directing high volumes of internet traffic towards targeted servers in a bid to knock them off-line.
The country has been shaken by more than two years of sometimes violent protests over a host of issues including fears among the opposition that President Macky Sall may seek a third term in office in the February 2024 election.
The opposition has also accused Sall’s government of using the judicial machinery to target potential challengers such as popular opposition politician Ousmane Sonko, who placed third in the 2019 presidential race. The authorities deny ongoing legal cases against Sonko are politically motivated.
On its Twitter account, the so-called Mysterious Team group says its members are “cyber warriors from Bangladesh”.
The group is little-known, but has carried out previous cyberattacks against the Ethiopian health ministry and Indian media, according to the European Repository of Cyber Incidents, an independent research consortium that analyses cyber incidents.
