Do not trust the Block Hack website
Written by Tomas Meskauskas on (updated)
What is Block Hack?
This website is advertised as a console to redirect unconfirmed Bitcoin cryptocurrency transactions to the provided BTC wallet. No less than two antivirus scanners on VirusTotal detected this as a phishing website.
Research shows that the site also contains a login form, which could be used to steal login credentials. Since this web page is crypto-related, it might be used to hijack Bitcoin wallets.
More about the Block Hack scam
Users log into to this page using the created account, or login with their Google or Facebook accounts. Do not provide any personal information (in this case, login credentials) on these websites. Any provided information could be stolen and misused for various malicious purposes. For example, to access personal data, make fraudulent purchases and transactions, and deliver malware.
As mentioned, this page is cryptocurrency-related and, therefore, it is possible that website developers could be using it to hijack (steal) Bitcoin wallets and use them to send cryptocurrency to their own wallets. It is also possible that developers of this page could use it to trick users into paying for 'services' (e.g., for a console that redirects unconfirmed Bitcoin transactions to the provided BTC wallet).
In any case, this is a dubious website and its developers have malicious intent. These are the main reasons why this type of website can never be trusted.

Similar scams in general
Some examples of crypto-related scams are "Generate Bitcoin Scam", "BTC Giveaway", and "Double Your Bitcoins".
Some phishing websites are used to steal login credentials (usernames, email addresses, passwords) and also social security numbers, credit card details, bank account numbers and other data, which is monetized in various ways.
People who fall for these phishing scams usually lose access to personal accounts, have their identities stolen, lose money, or encounter other serious problems. Note that phishing websites can be promoted through various unwanted applications. Typically, users download and install rogue apps on browsers or computers inadvertently.
How did unwanted applications install on my computer?
Shady apps are distributed via download/installation set-ups of other products. This deceptive marketing tactic of packing regular software with unwanted or malicious additions is called "bundling".
Rushing download/installation processes (e.g. ignoring terms, skipping steps and settings, etc.) increases the risk of inadvertently allowing bundled content into the system.
Some dubious apps have "official" download sites. Intrusive advertisements proliferate these applications as well. Once clicked, they can execute scripts to download/install unwanted apps without users' consent.
How to avoid installation of unwanted applications
You are advised to download files and programs from official websites and via direct download links. Other tools and sources such as third party downloaders and installers, unofficial pages, and Peer-to-Peer networks (e.g., eMule, torrent clients) should not be used to download or install software.
Check all "Custom", "Advanced" and other similar settings (or available checkboxes) for offers to download and/or install unwanted apps. Do not click ads on dubious websites, since they can be designed to open bogus web pages or cause unwanted downloads and installations.
Remove any unwanted, suspicious extensions, plug-ins and add-ons installed on the browser, and software of this kind from the operating system. If your computer is already infected with rogue apps, we recommend running a scan with Combo Cleaner Antivirus for Windows to automatically eliminate them.
