Vishing

Security

Vishing is a new important word which is good to know. It’s not important to know the word but it is important to know what is behind this word. The word vishing was made by combination of the words voice and phishing. You probably heard about phishing and you probably even had some phishing emails in your mailbox. The fake emails that want you to enter your bank account credentials are only small part of the phishing. Phishing together with social engineering can make devastating damages – stole money from your bank account, stole sensitive data from your computer or hack whole company network.

Email revolution

Nezařazené

Securing of the email communication can’t go through evolution and there has to be a revolution. Phishing and spam is one a rise. There are attempts how to mitigate spam and phishing by better antispam filters and by technologies like SPF, DKIM and DMARC. Unfortunately these technologies are still only an option and they are not mandatory. When Google claimed that all websites on HTTP protocol will be marked as unsecure and only websites with HTTPS protocol will be shown in "normal way" it started a revolution. All the websites started using secure protocol and even it was possible to obtain a certificate for free. There wasn’t such revolution with emails and it should be. I understand that mandatory validation by SPF and DKIM doesn’t solve all problems. For example…

What can computer security experts gain from pilots?

Computer tips

At the first sight computer systems and flying are completely different areas. Even though computer security experts can learn something from pilots. Computer security is quite young if you compare it with flying and therefore it is a normal state that government is in state of establishing institutions for fighting the cybercrime. The primary target is to secure government and other state institutions such as healthcare. It is not like in flying that investigation of the accident will help all other pilots to avoid such circumstances. It is partly understandable because the results from investigation can reveal the hole to other hackers but in my opinion there must be in future stronger role of the government in fighting the hackers and helping outside of the government. The second inspiring area…

Network Attached Storages (NAS) from Synology have function Snapshot Replication. This service allows you synchronize your data in set-up time interval across several NASes. This function is suitable if you need to have local copy of your data at several locations no meter if it is because of the quick access to files or it is way of backup at several locations. Detailed information for this service is in help but I would like to share my solution when the synchronization didn’t work. We synchronize several areas in five tasks which are started during night.

Network attackers

Computer tips

As you know there are some attackers that may try to break into your network. Although they might use for their attack infected computers from over the world (and it is the most often strategy) sometimes you may encounter attack from multiple computers in one network. I collect the IP address of these attackers and I would like to share the top eleven networks, where there were at least 8 attacks from different computers. I’m just curious if these are broken networks or these networks are owned by some hackers. 185.222.209.X (Netherlands) 21 attacking computers 91.200.12.X (Ukraine) 21 attacking computers 37.49.224.X (Netherlands) 20 attacking computers 141.98.80.X (Belgium) 12 attacking computers 222.52.118.X (China) 12 attacking computers 157.122.148.X (China) 11 attacking computers 185.234.217.X (Ireland) 11 attacking computers 37.49.226.X (Germany) 10 attacking computers…
