"Transaction received into blockchain wallet" email scam removal guide

What is the "Transaction received into blockchain wallet" email?

"Transaction received into blockchain wallet" is a scam email. These letters are disguised as mail from Blockchain, Bitcoin cryptocurrency block explorer and cryptowallet service, which supports Bitcoin, Bitcoin Cash, and Ethereum cryptocurrencies. The emails are presented as notifications about a recent transaction. The purpose of the "Transaction received into blockchain wallet" letters is to trick users into visiting cryptocurrency-related phishing websites. Which in turn are designed to extract information relating to users' cryptowallets and steal them.

The emails, with the title/subject "Transaction Received of BTC 0.55615081 has been processed." is full of grammatical and spelling errors, which is common for scam mail. The subject of these letters serves as a lure to trick recipients into opening them. This title suggests that users have received 0.55615081 BTC (Bitcoin cryptocurrency), which (while the exchange rates can drop and rise drastically) - can be of significant worth. At the current exchange rate, this sum would be worth approximately 5 600 USD. The body of the email, states that users have received a payment in their Blockchain Wallet. To view details of this transaction, recipients are instructed to click the link, presented below as a button - "Confirm Your Transaction". Should users find they cannot open the link, they are to address this issue via email. This button will redirect to a cryptocurrency-centered phishing site, which gathers entered information. For example, such websites can identically mimic the design of the log-in pages of legitimate sites (e.g. disguised as Blockchain). Thereby, allowing scammers / cyber criminals to gain control over the accounts, users were attempting to access. Therefore, trusting the "Transaction received into blockchain wallet" emails can lead to financial losses and serious privacy issues.

"Last Warning: Upgrade your email to avoid Shutting Down", "A file was shared with you", "ShareFile Attachment" and "ProtonMail Email Scam" are a few examples of other phishing emails. Deceptive/Scam letters are sent during large scale operations called "spam campaigns". Phishing is not the only heinous use for such mail, other scams are also common. These emails are employed to distribute trojans, ransomware and other malware as well. Regardless of what these emails are presented as, what they claim, request or demand - the end-goal is the same - to generate revenue for their designers.

How do spam campaigns infect computers?

Systems are infected via virulent files, sent through spam campaigns. These files can be attached to the emails or alternatively, the letters can contain download links of such content. Malicious files can have various disguises (e.g. deceptive filenames, thumbnails, etc.) and can be in various formats, like: PDF and Microsoft Office documents, archives (RAR, ZIP, etc.), executables (.exe, .run, etc.), JavaScript, and so on. When these files are executed, run or otherwise opened - it triggers the infection process (e.g. download/installation of malware). For example, Microsoft Office documents infect systems by executing malicious macro commands. In MS Office versions released before 2010 - macros are executed the moment a document is opened. However, in newer versions - users are asked to enable macro commands (i.e. to enable editing/content). Hence, the infection process is only jumpstarted after macros are manually enabled.

How to avoid installation of malware?

Suspicious and/or irrelevant emails should not be opened, especially any attachments or links found in them - as doing so can lead to a high-risk infection. It is recommended to use Microsoft Office versions released after 2010, since they have "Protected View" mode. This mode prevents malicious macro commands from being executed automatically, when an infectious document is opened. Aside from spam campaigns, other common malware proliferation methods include via untrustworthy download sources (e.g. unofficial and free file-hosting sites, Peer-to-Peer sharing networks and other third party downloaders), illegal activation ("cracking") tools and fake updaters. Therefore, it is strongly advised to only use official/verified channels, activate and update programs with tools/functions provided by legitimate developers. To protect device and user safety, it is paramount to have a reputable anti-virus/anti-spyware suite installed. Furthermore, this software must be kept up-to-date, used to run regular system scans and to remove detected threats. If you've already opened malicious attachments, we recommend running a scan with Malwarebytes for Windows to automatically eliminate infiltrated malware.

How to remove malware manually?

Manual malware removal is a complicated task - usually it is best to allow antivirus or anti-malware programs to do this automatically. To remove this malware we recommend using Malwarebytes for Windows. If you wish to remove malware manually, the first step is to identify the name of the malware that you are trying to remove. Here is an example of a suspicious program running on a user's computer:

Click 'Options' at the top and uncheck 'Hide Empty Locations' and 'Hide Windows Entries' options

manual malware removal step 5Check the list provided by the Autoruns application and locate the malware file that you want to eliminate.

You should write down its full path and name. Note that some malware hides process names under legitimate Windows process names. At this stage, it is very important to avoid removing system files. After you locate the suspicious program you wish to remove, right click your mouse over its name and choose "Delete".

locate the malware file you want to remove

After removing the malware through the Autoruns application (this ensures that the malware will not run automatically on the next system startup), you should search for the malware name on your computer. Be sure to enable hidden files and folders before proceeding. If you find the filename of the malware, be sure to remove it.

searching for malware file on your computer

Reboot your computer in normal mode. Following these steps should remove any malware from your computer. Note that manual threat removal requires advanced computer skills. If you do not have these skills, leave malware removal to antivirus and anti-malware programs. These steps might not work with advanced malware infections. As always it is best to prevent infection than try to remove malware later. To keep your computer safe, install the latest operating system updates and use antivirus software.

To be sure your computer is free of malware infections, we recommend scanning it with Malwarebytes for Windows.
