Malware authors often expand the capabilities of malware in an attempt to launch sophisticated attacks. In the past 24 hours, security experts have come across new variants of three existing trojans, namely, Astaroth, Zeus-sphinx, and Anubis. While the new variant of Zeus-Sphinx was widely distributed in the first quarter of 2020 via malspam featuring coronavirus relief payment updates, the new Astaroth version shared its C2 server via an URL hidden in a YouTube channel description. Meanwhile, the new variant of Anubis trojan, which is under active development, will allow attackers to get granular details of an infected device.
The terror of Maze ransomware was also witnessed in the last 24 hours. In its latest attack attempt, the notorious ransomware had tried to infect Pitney Bowes. However, the attack was partially successful as threat actors could only steal some data from the company.
