When analyzing Japanese phishing emails targeting Japan over a period of about one month, below is very common.
> X-Mailer: Foxmail 6, 13, 102, 15 [cn]

This trend has been observed not only in the past month, but for a long time.
Foxmail is a famous Chinese email client.

#Phishing #钓鱼 网络安全
二手域名很便宜,而且钓鱼网站只使用几天,所以与过期相近没有关系。
本来中国和其他国家相比,二手域名的买卖很活跃

#Phishing #china
Recently, there's been a trend toward many phishing sites targeting Japan with Chinese .cn domains nearing expiration.
I's likely due to the bulk purchase of used domains at low prices.

令和6年のたった1年で、SNS型投資詐欺・ロマンス詐欺の被害金額は1271.9億円。
被害者が届け出をしていない・騙されたことに気付いていない、というケースを考えると、この倍以上はあるだろう。
この騙し取られたお金が、正しく医療や福祉に使われたら、どれだけの人が助かっただろう……? ガックリしちゃうな
