Google warns that cyber hackers are using compromised cloud accounts to mine cryptocurrencies.

Details of mining hacks are included in a report by Google’s cybersecurity action team. This report provides advice on how Google can identify and address hacking threats to cloud services, which are remote storage systems that store customer data and files offsite.

Other threats identified by the team in the initial threat horizon report include: A Russian national hacker trying to get a user’s password, warning that he is the target of a government-sponsored attacker. A North Korean hacker disguised as a Samsung recruiter. Use of advanced encryption in ransomware attacks.

Mining is the name of the process that regulates and validates blockchains, such as the blockchains that underpin cryptocurrencies, and requires a great deal of computing power. Google reported that out of the last 50 hacks of cloud computing services, more than 80% were used to perform cryptocurrency mining.

Q & A What is blockchain technology?

Blockchain is a digital ledger that provides a secure way to create and record transactions, contracts, and contracts. However, the database is shared across your computer’s network, rather than being stored in one place like a traditional ledger.

This network can contain only a handful of users, or hundreds or thousands of people. The ledger is a long list of transactions that have occurred since the start of the network and grows over time.

The blockchain database consists of blocks and transactions. The block contains a batch of hashed and encoded transactions. Each block contains a hash of the previous block. This links the two to form a chain. This process validates each block to the original block and is essential for database security.

Blockchain technology has been around for years, and the most well-known use to date is the cryptocurrency Bitcoin. However, the use of blockchain is not limited to financial transactions, and enthusiasts are looking at other applications of this technology, especially the types of transactions that frequently have conflict and trust issues.

The victim was then directed to a malicious link to malware stored on Google Drive, which is currently blocked.

Google said it would be difficult to deal with ransomware attacks where files and data on a user’s computer would be encrypted by an attacker until the release was paid for. This report shows the emergence of Black Matter, described as a dreaded ransomware family.

But earlier in the month, Black Matter said it was closed due to pressure from authorities. Victims of Black Matter include the Japanese technology group Olympus.
