2026-04-13 (Monday): #XLoader (#Formbook) infection.

A #pcap of the traffic, the associated email and #malware samples are available at https://malware-traffic-analysis.net/2026/04/13/index.html

2026-04-09 (Thursday): Finally got the #KongTuke CAPTCHA page and associated #ClickFix instructions today!

KongTuke CAPTCHA page traffic:

- hxxps[:]//windlrr[.]com/file.js
- hxxps[:]//windlrr[.]com/t
- hxxps[:]//windlrr[.]com/g
- hxxps[:]//windlrr[.]com/g
- hxxps[:]//windlrr[.]com/c?tk=a19806998b1234b63f73ef741e1b749d

URL from clipboard-injected script:

- hxxps[:]//oeannon[.]com/t2?tk=5f7edb3752dd5b85eda86711724abd44

Last URL I got on a VM (nothing returned):

- hxxps[:]//plein-soleil[.]top/o

2026-04-09 (Thursday): I found a site with inject script for both the #KongTuke and #SmartApeSG campaigns. Only got #SmartApeSG

Zip archive payload: c0d91df99b279ebfd952dadf0d1b94e436defa6bb59752cfad13777187f88553

Saw the same possible data exfiltration traffic to the same server at 89.110.110[.]119:443 that I saw from the previous payload from SmartApeSG campaign I reported on Monday 2026-04-06.

2026-04-06 (Monday): #ClickFix activity from the #SmartApeSG campaign. Not sure what malware was sent through the fake CAPTCHA page is this time, but it's not the usual.
