This new report is kind of a wake-up call. KnowBe4 says 86 percent of phishing attacks are now AI-driven, and it shows. It is not just email anymore either. Attackers are hitting Teams, calendar invites, and basically any tool people trust at work. The scary part is how convincing this stuff is getting, especially with internal impersonation and multi-channel setups. At some point, it feels like companies may need AI defending them just to keep up, because humans alone are going to have a harder time spotting this.

This new Linux kernel bug called Copy Fail (CVE-2026-31431) is kinda terrifying because it’s not complicated at all. A normal user can run a tiny 732-byte script and get root, no race conditions or luck required, and it works across major distros like Ubuntu, RHEL, and SUSE. The exploit quietly modifies the page cache instead of the file on disk, so integrity checks don’t catch it, but the kernel still executes the tampered version in memory.

Even worse, since the page cache is shared, it can potentially cross container boundaries too. Patch ASAP if your distro hasn’t already, because this one feels way too reliable…
