Topic: Blockchain/Cryptography

The Internet continues to live in the realms of a dangerous environment where threats are in an abundance. Many people in today's society aren't taking the initiative to protect themselves from the array of problems they can find themselves in from cybersecurity related issues. To add to the ongoing list of problems, the world is experiencing a new issue in the name of "cryptojacking", "which secretly uses your laptop or mobile device to mine cryptocurrency when you visit an infected site" (Newman). Cryptojacking definitely has some unique features to take into consideration.

Cryptojacking is a new concept in itself that it has gained popularity over the last couple of weeks. According to the text, "Instead, the latest technique uses Javascript to start working instantly when you load a compromised web page" (Newman). Individuals will not immediately know if the website they are visiting has been compromised or not. Digital profit may be earned in the likes of getting access to your device or even utility bills that you pay. This craze started when a company called Coinhive developed a script that would starting mining Monero, a cryptocurrency when a specific webpage is loaded. There are countless ways to protect yourself from this arising trend.

Taking time to prevent any security breaches may be a life lesson to learn. In ensure best practices, "To protect yourself from cryptojacking, you can add sites you're worried about, or ones that you know practice in-browser mining, to your browser's ad blocking tool" (Newman). Everything may be happening in front of your eyes and you may be clueless in the entirety.

What security related issues have you personally encountered? What specific measures have you taken to protect yourself from any type of attack?

Thanks for reading and I hope to hear your thoughts to this post!

Best,

  1. Hey Andrew! Very fascinating write up- well done. I personally have experienced a few security issues regarding my personal email set up. I have been blocked from accessing it multiple times as it was hacked and taken over. After dealing with this problem multiple times, I took action to be wiser with whee I would be logging into my email, and on which devices. I hope to never deal with such a hassle again!

  2. Hi Andrew! I really like your post and the topic that you chose. I wasn't aware of this new type of hacking method that has recently surfaced. I agree with what you said in your post, many people are unaware or fail to take precautions simply because they believe they are protected. However, I personally do use ad blocker which allows you to add sites which you want it to stop from loading/visiting. it.
    Though, for people who haven't been exposed to a compromised webpage it is difficult to know which site is bad or good to add it to the ad block list.

  3. Hi Andrew! This is a fun post for me because I attended the IT summit blockchain talk. It seems to me that to hijack and mine for cryptocurrency they would have to install software enabling your computing power and network to be used as a node. This should be noticeable in your bills upon little inspection. Most of the time, for nodes to actually mine for data and compete with other nodes to form a block, your computer most designate a certain portion of time (let's say six hours) to be a full node and have the ability to mine currency by adding a block to the block chain. For a browser to be doing that in the background without a user knowing is beyond me, crytojacking is nuts.
