3. What was the #1 most-wanted malware for 2018?
   CryptoJacking using Coinhive

[muradawad]

1. Hard fork drop of Monero coupled by huge drop of the crypto market.

2. Cryptojacking is the unauthorized use of someone else’s computer to mine cryptocurrency. Hackers do this by either getting the victim to click on a malicious link in an email that loads cryptomining code on the computer, or by infecting a website or online ad with JavaScript code.

3. Coinhive

1. Two factors that caused CoinHive to become economically inviable.
   The hard fork that dropped he hash power by 50% and crypto winter witch saw the Monaro price drop by 85%.
2. Cryptojacking is a special kind of malware that hides on your computer and steals its computing resources to mine cryptocurrencies.
3. The most wanted malware of 2018 was CoinHive.

1. What two factors caused CoinHive to become economically inviable?
   50% drop on hash rate because of hard fork
   The service was reportedly also hit by the [cryptocurrency] market drop off.

2. What is cryptojacking?
   Cryptojacking is the unauthorized use of a computing device by cybercriminals to mine cryptocurrency.

3. What was the #1 most-wanted malware for 2018?
   The top three most wanted malware strains were all cryptojacking-related with Coinhive.

Questions:

1. What two factors caused CoinHive to become economically inviable?

drop in Monero’s Hash rate and Market price

2. What is cryptojacking?

Mining Monero by hijacking someone else’s browser, and therefore their CPU, to mine it for you

3. What was the #1 most-wanted malware for 2018?

Coinhive, a JavaScript-based digital currency mining service, was the target of malicious malware cryptojacking code making 3 iterations this code to be 3 of the Most wanted in 2018

[Cestrada]

1. The 2 factors that caused CoinHive to not be viable were a greater than 50% drop in hash rate following XMR hard fork and the 85% correction of Monero in the bear market.
2. Cryptojacking is when a hacker installs a code on a website and is then able to mine using the computing power of the browser that loads the website.
3. Web browser based CoinHive mining code

Coinhive - Reading

1. The two factors that caused Coinhave to become economically unviable are:

• over 50% in hash rate following the last Monero (XMR) hard fork.
• cryptocurrency market drop off value of XMR slumped of 85% within a year.

2. Cryptojacking is a stealth crypto mining attacks - work by installing malware that uses a computer’s processing power to mine for cryptocurrencies without the owner’s consent or knowledge.

3. The # 1 most wanted malware for 2018 is Coinhive - a web browser based Monero (XMR) mining code

[bdoherty]

1. What two factors caused CoinHive to become economically inviable?

• 50 percent drop in hash rate following the last Monero (XMR) hard fork
• Value of Monero slumped over 85 percent within a year

2. What is cryptojacking?
   Using some of the computing power of a users browser to mine cryptocurrency without their consent.
3. What was the #1 most-wanted malware for 2018?
   Cryptojacking using Coinhive

[Mihir23]

1. The first factor includes an over 50 percent drop in the hash rate caused by Monero’s hard fork. Secondly, the market value of XMR (Monero) suffered an 85 percent decrease within a year. These two factors led to the discontinuation of CoinHive.

2. Cryptojacking is a form of cyber attack where the attacker installs a cryptomining code into the target’s computer to hijack its processing power to mine cryptocurrency. Users can be prone to this attack if they click on a malicious link, malware advertisement, or install a malicious web browser extension.

3. In 2018, Israeli cybersecurity firm Check Point stated in their Global Threat Index report that crypto-jacking-related with Coinhive was the most wanted malware.

1. The scheduled hard fork of Monero which saw a steep decline in hash rate of over 50% and the crash in price of XMR.
   2.It is when a hacker gain access to a device for the purpose of using it to mine cryptocurrency. The computer runs the mining algorithms and sends the data back to the hacker.
2. Coinhive was the most wanted malware code.

[bbss]

1. It was a over 50 percent drop in hash rate following the last Monero hard fork, and the value of XMR slumped over 85% within a year.
