Check your own ports on the Internet

There are some good tools on the Internet (free)

Like this one:  http://www.yougetsignal.com/tools/open-ports/

This is just a basic port scan (likely tcp open check)

unfortunately a hacker will use multiple scans and some of the different flags a packet can have.   There are 2^8 ports and 6 different flags for packets (SYN/ACK/RST/FIN/URG/PSH)

A good place for the information is rfc 793.

There are also udp scans for the udp programs (like DNS and others)

while you are working and living your life, hackers are trying to get through your devices nonstop and the reason is:

 

while you are sleeping, China and others in Asia are probing.

Also in early morning east European hackers are attacking.

And of course in the US we have many hackers here as well.

 

Attacks are coming – nonstop.

Scan your systems and we will create reports

Check a website before changing your password

Use LastPass check which allows the user to test a website to know whether it has updated the openssl technology.

Some site do not have this type, and may not matter, and others may have openssl and have patched.

But yet others may not be aware of this vulnerability… and if that is the case you can assume a hacker may be able to capture your password  even though your lock is on the browser.

 

this vulnerability means the gold lock is not working for some websites out there.
