SMTPTX is a very simple tool used for sending simple email and do some basic email testing from a pentester perspective. Its able to send messages without depending on knowing a specific MTA/SMTP server beforehand. Unlike tools like sendemail it handles the MX record resolution itself and connects to the relevant server and sends the email. Its able to add attachments, use TLS and do SMTP authentication, specify custom DNS servers and SMTP servers etc. More features are under way.

0x90 Site Certificate Trouble

Unfortunately my SSL certificate renewal was borked as my ISP missed my request. So here we are, having an expired certificate and a lot of links spread throughout the internet using the HTTPS prefix...Doh! Really bad timing for this site release. Well, hopefully it will be resolved within a couple of days.

I'm sorry for any unconvenience.

This is a strategic choice on my part as we need to join forces, as many as possible, in the battle against malware and the forces behind it.

Unlock Huawei Datacards

In Sweden the Huawei datacard is probably one of the most widely used datacards around. They are offered by operators to attract consumers to their services by offering them very cheap at low rates and such. However this comes at a price. Sometimes the consumers are locked to a single operator for up to 24 months. Even when this time has passed, the data card remains locked, which can be very unfortunate for the consumer. Let's go about and see how they can be unlocked...
