Crypto mining hacks

The cryptocurrency-miner, a multi-component threat comprised of different Perl and Bash scripts, miner binaries, the application hider Xhide, and a scanner tool, propagates by scanning vulnerable machines and brute-forcing primarily default credentials. The threat also employs a process hider to conceal the miner binary, which makes a typical user more unlikely to notice the mining activity save for a drop in performance and suspicious network traffic. This method has been a known cover for threat actors that aim to scan, brute force, and mine. The attacker starts by gaining access to a machine through weak or default credentials. Then, a command will be run on the compromised machine:. The initial file min detected as Trojan.

Hackers are using Cloud accounts for crypto mining, Google issues warning

Attackers are exploiting poorly configured cloud accounts to mine crypto, Google warned users in a recent report. Cryptocurrency mining is a computationally intensive activity. And Google Cloud customers can access it at a cost. However, miners are now hacking Google Cloud accounts for mining purposes. The report also provided cybersecurity threat intelligence to cloud users.

In the report, the cybersecurity team analyzed 50 recently compromised Google Cloud accounts. The report also stated that in the majority of these incidents, the hackers downloaded crypto mining software to the compromised accounts within 22 seconds. The attacks were scripted, and it would have been impossible to manually stop them.

However, as reported by the cybersecurity team, the crypto mining hacks were not the only attacks. The attackers targeted 12, Gmail accounts in a mass phishing attempt. They attempted to trick users into handing over their login details.

Google, however, said it had blocked all the phishing emails, and no user was compromised. The report also pointed out an attack by a North Korean government-backed group. This hacker group posed as Samsung recruiters, sending fake job opportunities to employees at South Korean information security companies. They attached a malicious link to malware stored in Google Drive.

Google said it also blocked it. In the report, Google mentions the formidable Black Matter ransomware group. And although the group announced that it was shutting down earlier this month, Google is still cautious. Until this is confirmed, Black Matter still poses a risk. And also vulnerabilities in third-party software that the users install. The report also recommends a few ways to prevent these attacks.

Someone stole $120 million in crypto by hacking a DeFi website

The Bitcoin network is burning a large amount of energy for mining. In this paper, we estimate the lower bound for the global mining energy cost for a period of 10 years from to , taking into account changes in energy costs, improvements in hashing technologies and hashing activity. We estimate energy cost for Bitcoin mining using two methods: Brent Crude oil prices as a global standard and regional industrial electricity prices weighted by the share of hashing activity. Despite a billion-fold increase in hashing activity and a million-fold increase in total energy consumption, we find the cost relative to the volume of transactions has not increased nor decreased since This is consistent with the perspective that, in order to keep the Blockchain system secure from double spending attacks, the proof or work must cost a sizable fraction of the value that can be transferred through the network. Bitcoin is a digital currency launched in by an anonymous inventor or group of inventors under the alias of Satoshi Nakamoto Nakamoto, It is the largest cryptocurrency in market capitalization with over billion dollars Chan et al.

The Cost of Bitcoin Mining Has Never Really Increased

We live in a digital age, with more people than ever doing most, if not all, their financial transactions and shopping online. With this also came the rise in cryptocurrencies.

Cado Security has determined that the attacks were conducted using compromised SSH secure shell logins from universities in Canada, China and Poland, using similar malware file names, the same vulnerability and shared technical indicators. That suggests they might be the work of the same bad actor. This could be a pure cash grab that relies on the power of supercomputers to mine digital currency more effectively than regular PCs. However, Cado and others have observed that this comes right as many institutions are repurposing their supercomputers for COVID research. Sign up.

4 types of cryptohacks, explained

As bitcoin and other cryptocurrency prices soar, "cryptojacking" attackers surreptitiously take over web browsers, phones and servers to make some serious profit. We forecast it to be the biggest threat in Cryptocurrencies, like bitcoin and Monero, are created by using computing energy to solve complex math problems. When a problem is solved, a new piece of currency is made. This is called mining.

Crypto exchanges keep getting hacked, and there's little anyone can do

Cybercriminals have been caught exploiting misconfigured Docker installations to spread crypto-mining malware. Researchers at Cisco Talos identified the tactic after a cryptocurrency-mining botnet strayed onto a honeypot-system set up to track Docker-related threats. The Xanthe botnet has been active since March without previously getting documented, according to Cisco Talos.
