"SD BIOSENSOR Email Virus" removal guide
What is "SD BIOSENSOR Email Virus"?
"SD BIOSENSOR" is yet another Coronavirus/COVID-19 themed spam campaign. The term "spam campaign" is used to define a large scale operation, during which thousands of deceptive/scam emails are sent. The letters are disguised as mail from a legitimate global bio-diagnostic company - SD BIOSENSOR. These emails are presented as important orders concerning the pandemic. However, instead of containing this information, upon opening - the attached Excel file initiates download/installation of MassLogger malware.
The "SD BIOSENSOR" emails with the subject "Quotation Request ARN200618-1" (titles may vary) state that their contain an urgent Coronavirus/COVID-19 pandemic order. The letters state that the attached file is supposedly a request under the number/code ARN200618-1. Additionally, recipients are urged to inspect the equipment and products in the listed website. Recipients are told that a speedy response would be greatly appreciated. Instead of containing the aforementioned request, then attached Excel spreadsheet ("SD Technology Co. Ltd_RFQ_ARN200618-1.xlsm") is designed to infect systems with MassLogger. This piece of malicious software is designed to steal information. Following successful installation, it attempts to extract account log-in credentials (e.g. usernames and passwords) from certain browsers, communication apps / messengers, as well as email, VPN (Virtual Private Network) and FTP (File Transfer Protocol) clients. Furthermore, MassLogger has keylogging abilities. In other words, this malicious program can record key strokes. This functionality can also be used to steal victim's accounts and other sensitive typed information. Cyber criminals typically target email, social media, social networking, messaging, data storage, file sharing, e-commerce, online money transferring, cryptocurrency wallets (cryptowallets), banking and other accounts. To summarize, trusting the fake "SD BIOSENSOR" emails can result in system infections, financial losses, severe privacy issues and identity theft. If it is suspected or known that MassLogger (or other malware) has already infected the system - anti-virus software must be used to remove it immediately.

"Secure Parking", "Audit and Assurance", "BOTAS" are a few examples of other malware-proliferating spam campaigns, and "Institut za zdravstvo Srbije", "U.S Department of Labor", "COVID-19 test" are some Coronavirus/COVID-19 centered spam campaigns. The deceptive emails distributed through these operations are usually presented as "official", "urgent", "priority" and similar. Much like the "SD BIOSENSOR" emails, scam letters can be disguised as mail from genuine institutions, organizations, companies, service providers, etc. However, distribution of malicious programs is not the sole purpose of such emails - they can also be used for phishing and other scams. Regardless of what this mail claims, offers, requests or demands, the end-goal is the same - to generate revenue to the scammers / cyber criminals behind it.

After you locate the suspicious program you wish to remove, right click your mouse over its name and choose "Delete".
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.
