Hi, some months ago I sent some emails to misc (search my email on google) because I believe my obsd laptop was been hacked. Then I bought a new laptop because my suspicious were that some firmware or the bios had some infected code. Then I taken the new laptop and I went in two wifi point (in two different days and in two different wifi spot) to install openbsd. I installed a basic system and firefox, after that I come back to home. At home I tried to complete the installation adding other packages. After one hour between pkg_add and watching video on youtube my laptop was freezed. The freeze was happen im the middle of a pkg_add. After that I forced a reboot and I completed the installation. Then I start to watch a video on youtube. Then after 15 or 20 minutes from the boot the system again has been frezzed. Again forced reboot. And again watching a youtube video, around 10-20 minutes again freeze. In total there was been 3 freeze, one on pkg_add and two during watching a youtube video. At the fourth boot, I left the system disconnected from the wifi to verify if it was an hardware problem. After 15 minutes I connected to the wifi but without doing anything. Then after other 10 minutes I opened youtube but the system was pretty stable. Those freeze was happened maybe 10 days ago. But I haven't had other freeze. Now the "signs" of the previous hacking are appeared again in the new laptop then most probably the laptop was been hacked again.
What is your opinion ? could be a MITM from my router and a kernel 0day on the tcp/ip stack implementation ? could be MITMed pkg_add ? the encryption algorithm (AES_128_GCM) behind https is really secure ? Can some code be injected in an encrypted stream ? Thank you. Cord.
