A new module for the infamous trojan known as TrickBot has been deployed: A stealthy backdoor that researchers call BazarBackdoor was first spotted being delivered as part of a phishing campaign that began in March. The campaign used the legitimate marketing platform Sendgrid to reach targets in a mass-mailing fashion; however, the emails were well-crafted, with the operators making an effort to make the phishing links inside the emails look legitimate. The malware is capable of providing full access to an attacker which can be used as a point of entry for any number of attacks.
