Email accounts compromised in a secure email phishing campaign

The NCSC-FI has received large numbers of reports about secure email-themed phishing messages in recent months. A new campaign became active in mid-April. According to the NCSC-FI's statistics, email accounts have been hacked in twenty different organisations. The NCSC-FI estimates that a five-figure number of secure email phishing messages has been sent in Finland in April. Multi-factor authentication is still an effective way to prevent accounts from being compromised.
