As everybody is aware, Ransomware has been in the news for the last, three years at least. End-users and organizations being attacked by the bad guys are encrypting all information and asking for a few bitcoins in return for their data.
This has been a very profitable business for them as today one bitcoin equals more than AUD 12,000, and it has steadily grown over the last few years.
Now, the bad guys found that some customers decided not to pay the ransomware as there have been mitigation strategies to recover the data without losing much information, such as offline backups. As a consequence of that and their ways of getting “new” threat in the market, it has been seen an increasing number of attacks with the only objective of installing a cryptocurrency mining software.
Researchers estimate that there are more than 500,000 computers around the world currently running some sort of cryptocurrency mining software without the owner’s knowledge. Based on this number of computers the bad guys are making around US $4,500 per day running this mining software. This means they are making more than US $1.5 Mil per year, just using others people/organization’s computers.
If your computer is being used to mine cryptocurrency, the only difference that you will notice is that your computer will be running at 100% at all times, as this type of processes is highly intensive.
Bitcoin also isn’t the only cryptocurrency out there, there are more than 50 different types! Some of them are :
- Ethereum (US $930)
- Bitcom (US $10,000)
- Monero (US $290)
- Cardano (US $0.40)
- TRON (US $0.04)
- ICON (US $4.70)
- ARK (US $4.90)
- and many others.
As you can see they, are not after just your data anymore, but also your computer processing power. This does not mean that ransomware will disappear anytime soon and you should lower your guards. This means that there one more thing that we need to be aware and protect from.
Be safe out there, until next Malware Monday.
