Kali365
Kali365 is a Phishing-as-a-Service (PHaaS) kit first observed in April 2026 that generates victim-targeted lures across multiple operating systems to induce users into copying and pasting actor-controlled commands for local execution.[1][2][3][4] Kali365 incorporates on-demand device code generation and mirrors the copy-paste execution tradecraft associated with ClickFix. [3] Operators have used Kali365 to harvest victims' OAuth tokens and session cookies through adversary-in-the-middle (AiTM) interception, enabling account takeover.[1][5][2][3][4] Kali365 PHaaS was first observed in April 2026.[1] Kali365 has also been affiliated with other branding to include Octopi365 and Freedom365.[3]

||
| Enterprise | T1090 | Proxy |
Kali365 has leveraged Cloudflare workers as reverse proxy infrastructure.[1][3][4] |
|
| Enterprise | T1528 | Steal Application Access Token |
Kali365 has obtained OAuth access and refresh tokens by deceiving victims into completing actor-initiated device authorization requests, and intercepting authentication sessions with legitimate identity providers through adversary-in-the-middle reverse proxy infrastructure. [1][5][2][4] |
|
| Enterprise | T1539 | Steal Web Session Cookie |
Kali365 has captured session cookies and related session artifacts when the interacted phishing lure acts as proxy for legitimate requests with login services.[1][4] |
