New sign-in on email scam removal guide

What is New sign-in on email scam?

Phishing emails are used with a purpose to trick recipients into clicking on a website link or attachment that either install malware on the operating system or opens a page that cybercriminals use to steal sensitive, private information (e.g., login credentials, credit card details, telephone numbers, names, surnames, and so on). This email is used to trick recipients into providing email account credentials.

New sign-in on email scam email spam campaign

Email service providers send emails saying that a suspicious sign-in was prevented (or similar notifications) when they block attempts to access email accounts from different locations, devices, etc. In other words, email providers notify users about unusual sign-in activities. Scammers behind this phishing email attempt to trick recipients into believing that this is a legitimate email regarding a sign in on MailApp. It encourages users to reset their password via the provided website link if it was not them who signed into the MailApp. The link in this email opens a fake MailApp sign-in page asking to enter email account login credentials (email address and password) to access the account. To summarize, cybercriminals attempt to deceive recipients into thinking that they need to change their MailApp password to prevent the account from being stolen when in reality, they would use the provided login credentials to steal those accounts by themselves.

Typically, cybercriminals use stolen email accounts to spread phishing emails, trick other people into providing personal information, making money transactions, etc. It is also common for stolen accounts to be sold on the darknet or their login credentials to be used to perform brute-force attacks (to steal other accounts using the same or similar login credentials). In one way or another, all this can be avoided by not clicking links in suspicious emails or providing personal information on unofficial, dubious websites.

More examples of phishing emails used to trick recipients into clicking on a link or attachment that either infects the operating system with malware or opens deceptive page are "Banco De Espana", "Email Disabling Service", "Budapest Bank Email Virus", "Ministero Dello Sviluppo Economico Email Virus". It is important to know that such emails usually are disguised as important, official letters from legitimate companies, organizations that have nothing with them. A couple of examples of malware that cybercriminals spread via emails are TrickBot, Ursnif, LokiBot, and Emotet.

How do spam campaigns infect computers?

Usually, phishing/malspam emails that cybercriminals send with a purpose to trick recipients into installing malware contain some malicious attachment or a download link for a malicious file. Typically, some malicious Microsoft Office document (like Word, Excel), PDF document, ZIP, RAR or another archive file, JavaScript file, some executable file (like .exe, .run). It is important to mention that malicious MS Office documents ask for permission to run macros (enable editing or content), they cannot install malware without it. However, only when opened with MS Office 2010 or newer: these versions have the "Protected View" mode that prevents malicious documents from installing malware. Older versions do not have this feature. Therefore, malicious documents opened with older versions infect computers right after opening them.

How to avoid installation of malware?

Emails that are received from unknown senders, are not relevant and contain some attachment or a link are not trustworthy. It is very common that emails of this kind are used by cybercriminals as tools to spread various malware. Any software, files should be downloaded from official web pages and via direct download links only. It is not safe to use unreliable sources for downloading files or programs, such as Peer-to-Peer networks, third-party downloaders, unofficial websites, free file hosting sites, etc., or use third party installers. Installed programs must to be updated or activated with implemented functions or tools that are designed by official software developers only. Other (unofficial, third party) tools can be bundled with malware. Also, it is illegal to activate licensed software with such tools. And finally, it is important to scan the operating system for threats regularly and to it using a reputable antivirus or anti-spyware suite and remove them once the scan is completed. If you've already opened malicious attachments, we recommend running a scan with Combo Cleaner Antivirus for Windows to automatically eliminate infiltrated malware.
