My old Skype is sending Baidu spam

My old skype account that I haven’t used in over 4 years is sending my friends Baidu spam links. I tried logging in but couldn’t remember the password. I checked my old email on haveibeenpwned, and found out it was in a data breach from 2017 for Yu-Gi-Oh Dueling Network. Is this Yu-Gi-Oh data breach still available online? Because I can’t remember my old email password either. I don’t know if that’s how the hacker accessed my Skype but I can’t think of another way. PS; that email was my main e-mail from ages 12-19, so I’m worried about this leak. I really don’t know what to do… Thanks

Would spam on Stack Overflow developer story increase SEO ratings for my websites? [closed]

Imagine I start creating hundreds of Stack Overflow accounts. (I am not and I do not intent to do so in reality). I add a link to my site in the personal website space on the profile. I then make the developer story (CV) public. e.g. https://stackoverflow.com/story/kamilt

If such pages are searchable on Google and they contain links to my website, is it going to help with SEO for my website? Would it get me a better rank in Google because of it?

Accidentally clicked spam email link on android, risk of malware?

I was browsing my spam folder on my phone in the gmail app and stupidly let curiosity get the better of me. The app had blocked images by default but I clicked to allow them as well as accidentally clicked a link in the email while scrolling through. A page began to load but I closed it before anything visually loaded as soon as I saw the URL.

I was on a Oneplus 5 android phone connected to my home WiFi. Android version 9 with August 1, 2019 security patch. Gmail app last updated Feb 12th 2020. The gmail app had permissions to my contacts, calendar, and storage at the time I clicked the link. The phone is rooted with magisk but no root prompts were given so I don’t think this is an issue..?

The email was a spam email about someone who had viewed me on linkedin recently. From long-pressing to copy the url, the link I believe I clicked was http://mycity.citywork.vn/wp-content/uploads/2020/twisterrt.php

I’ve already run a malwarebytes virus scan from the mobile app on the phone (came up clean) and changed the passwords (from another PC) to all 5 emails that I had linked in the gmail app as well as cleared the app caches and storage.

I was wondering if any experts could let me know what damage could possibly have been done considering the scenario (android device, home network, gmail app, clicked links in possibly malicious spam email causing a page to load, but no further prompts, user input, or changes as far as I was able to see), as well as if possible to investigate the link to determine what it was attempting to do/load.

I’m a fairly technical (and fairly paranoid) person looking for a fairly technical answer in terms of the potential of whether something malicious could have been run/installed on the device and whether a full device wipe is recommended.

Thanks in advance for your help!

Foreign domain points to server and sends spam

I do have a really weird one. I am running a webhosting server that is being blocked by certain providers that use Cloudmark. I contacted the customer support and they got back with an email header that is unfortunately sending spam.

Received: from sub.domain.example ([1.1.1.1(my servers ip)]) Subject: sven.n.nilsson,=?utf-8?q?=62=65=6b=72=c3=a4=66=74=61=20=64=69=74=74=20=64=65=6c=74=61=67=61=6e=64=65=2e=2e=21=21=21?= From: =?utf-8?q?=53=77=65=64=69=73=68=20=6d=65=74=68=6f=64?=  <VNH9DI6HOW68YGD4AWRMSPB0VT7UWSHX5@gmail.com> 

The header states, that the mail came from my server. But how is that possible, I do have a closed relay and there is no mailbox for that domain. Furthermore, the domain is pointing to my servers’ IP. How can I prevent it from faking email headers and pointing to my servers’ IP?

What are spammers trying to acheive who the correct contact information in their spam?

I’ve recently received 2 spam SMS messages, claiming to be from 2 different organizations, but (obviously) not sent by them.

However, all of the contact details in the SMS match the real details of the organizations in question. Is this an attempt to perform a DDOS on the call centre, or is there some other point to this?

The second organization I called had a recorded greeting at the start saying – “we don’t send those messages, don’t respond to them.”, so they obviously got enough responses to be annoying.

I couldn’t find any reference to this phenomenon via a web search.

Stop modprobe spam

I setup GPU passthrough, it works, but ubuntu is spamming modprobe processes, it consumes lot of CPU, this is log from dmesg:

Mails sent from the command line not appearing in inbox or spam folder

I sent some test mails using the command line. In the log I can see that status = sent, but I am not getting any emails in my inbox or spam folder.
