Mexico's central bank confirmed that there was a cyber attack on Mexican financial institutions, in which the attackers siphoned around 300 million pesos from five institutions. According to the Governor of the Central Bank, the attackers tried to weaken the connection of financial institutions with the Interbank Electronic Payment System (Sistema de Pagos Electr¨®nicos Interbancarios,- SPEI) issuing fraudulent transfers, which affected the accounts of the institutions themselves. SPEI itself was not affected, and neither were the end users as their transactions occur in a separate system.
