How these Hackers Operate

The scripts are most commonly and easily spread by file sharing websites, in 2017 a file sharing site passed on a mining script that would generate cryptocurrencies for the site using user PCs without users knowing. According to some reports the trend is in the increase with hackers and antivirus companies competing to beat each other in terms of computer geniuses.

 Most websites get their revenue from adverts runned on the site 85% of which comes from google. Google allows users to copy the codes for the adverts and run them in their own website on another website. Attackers rewrite these ads codes to include scripts for mining cryptocurrencies. Many hackers currently prefer this kind of ‘business’ to holding user computing equipment hostages using ransomwares and demanding for ransoms.

Some anonymous hackers who had developed a sophisticated cryptocurrency mining algorithm seized numerou computer networks for mining cryptocurrencies in december 2017. These hackers always explore security loopholes in computer networks and sometimes bank on network leaks from the servers. The december 2017 attack earned the hackers a total sum of $68,000 worth of the cryptocurrency monero after successfully attacking 3 computer networks.

Why the cryptocurrency Monero being prefered by Hackers?

Monero, the 3 year old cryptocurrency has emerged as the lethal weapon of choice for hackers.

How does it affect your laptop and your smartphone?

Cryptocurrency mining leads to an increase in computer power consumption ranging anywhere between 80% to 100% meaning laptop users will see their batteries lasting just half the time it used to last before. With increase processing needs GPUs and CPUs are overworked resulting into overheating and sometimes damaging the of the processors.

Hackers have diversified platforms to include attacks on mobile gadgets too, smartphones and tablets have been reportedly attacked with monero mining scripts without the users knowing. Normally the android operating system which is the most used mobile operating system is attacked most with these annoying mining scripts.

For smartphone users it is a smart idea to install apps only from trusted publishers so you can be sure that the publisher does not include any other codes on to the apps. Installing a malare program is also and added advantage as the program would help clear unwanted codes lagging in the device system memory.

For web users running adblock programs can be helpful in detecting and blocking javascripts code that has cryptocurrency mining algorithms attached to them. Installing firewalls helps to break connection between auto insall mining programs with their remote servers. Without this connection, the necessary data cannot be reached to reproduce hashes.
