Технология, блокирующая спамерские домены оптом

Kaspersky has detailed a mail-protection feature that targets spammers who automatically register huge batches of similarly named domains using domain generation algorithms (DGA) to dodge blocklists. The technology clusters newly flagged "bad" domains by similarity and builds a single compact rule that blocks the whole batch at once, including domains never seen in a spam run before — for example a group like sxkjcc.asia, sxkjcd.asia and sxkjcy.asia can all be matched by one pattern. According to Kaspersky's own data, 44.9% of email sent last year was spam, which wastes employee time, clogs inboxes and often carries phishing or malicious payloads, making this kind of bulk domain detection relevant for corporate mail security products.
