Other attempts of impersonation of popular brands
Hackers have been using a variety of phishing campaigns to take advantage of the COVID-19 pandemic to distribute malware, steal credentials, and scam users and organizations out of money. Within May 2020, attackers launched many phishing campaigns and impersonated several popular brand names.
- The attacker impersonated the collaboration software provider, LogMeIn by sending fake yet legitimate-looking emails and directed users to a phishing site to compromise LogMeIn account login credentials.

- In an impersonating attack, attackers sent an automated Microsoft Teams notification email to steal the credentials of relevant accounts.
Organizations must train all their employees, test them on the latest threats, and ensure to follow prevention strategy. Organizations must also follow strong security policies and vigilance on the part of employees and create cyber resilience plans to avoid such attacks.
