October's cyber weather was stormy. In particular, the storminess is explained by the serious alert 1/2023 published in October, which warned of a wave of Microsoft 365 phishing and data breaches, which spawned hundreds of notifications of email account breaches in Finland. In addition, several critical vulnerabilities were published in October, many of which had already been exploited.
