Meltdown and Spectre

 

Happy New Year … Not!

With the New Year comes a new class of malicious attack that can impact IT systems. This time, the attack is hardware based, affecting mostly Intel based systems, and to some extent, AMD systems as well.

Here is a list of resources that highlight what it is all about and how to mitigate against this new threat. In the words of Microsoft, “Don’t panic.”

WARNING. Watch out for those email attachments.

It’s time to remind everyone again. Malware, Crypto Viruses and all kinds of nasties are still out there, and pose a bigger threat than ever.

And Sophos: The current state of ransomware – https://blogs.sophos.com/tag/ransomware/

Here’s a reminder from way back in 2012 on how to detect and identify these viruses when they pop up in your mailbox.

  1. DO NOT OPEN ZIP ATTACHMENTS.
  2. DO NOT OPEN ATTACHMENTS. Right click and save them to a temporary location on your computer, and check it out before opening it.
  3. DO NOT CLICK ON LINKS IN EMAILS. Hover your mouse over the link and be absolutely sure it is a legitimate link before you click on it.
  4. REVIEW THIS BLOG POST. Again. http://blog.powerbiz.net.au/security/how-to-detect-and-deal-with-malicious-email-viruses/

Passwords are the keys to your House

Have you ever gone out and walked up to someone you don’t know and given them the keys to your house?

Security (your keys, your alarm system, the locks and doors) are the protection you have for your physical home and the contents that you posses. We tend to look after these things fairly carefully.

In the electronic world today, people are less careful about the security in your “electronic” home. Your cloud accounts (email, data storage, shopping, banking, etc) define who we are just as much as our physical possessions. Yet, we tend to be less conscious about how we protect these personal “belongings”.

Jimmy Kimmel live put a reporter on the streets to interview people and as them what their password is.  The results? Well, see for yourself…

Guard your online privacy, and if you have one of these passwords (http://blog.powerbiz.net.au/security/here-are-the-worst-passwords-for-2013-do-not-use-these/), please change them ASAP!

Shellshock bug and NAS devices – QNAP, Synology and others

Oh, and by the way, check your NAS devices to ensure that they are safe. Disconnect direct Internet access right now, until the devices are patched.

http://www.neowin.net/news/shellshock-bug-impacts-nas-devices-like-qnap-and-synology

QNAP says that they are vulnerable to this, and urge users to take immediate action. http://www.qnap.com/useng/index.php?lang=en-us&sn=885&c=3036&sc=&n=22457

Apparently, Synology units are not generally affected (interesting…), but nevertheless, they are also coming out with a patch (also interesting…) https://www.synology.com/en-global/support/security/bash_shellshock

Resources for the Bash Bug (aka ShellShock)

It was bound to happen. A major bug targeting the Linux community, and not Windows users. Thanks to Trend Micro labs, here are some related resources that will bring you up-to-date with this latest threat.

More email Phishing and Malware – Take the Phishing Quiz

Here is an example of an email phishing attack. If you are using outlook, you can hover the mouse pointer over the link “click here”. DO NOT CLICK ON THE LINK. Just move the mouse over it. You will see the highlighted link, which has nothing to do with ebay or paypal. Always look for the part between “http://” and the next “/”. If that does not sat ebay.com or paypal.com or something that you are expecting, then it is a phishing/malware attack.
