Ransomware attacks have come back with a vengeance. More than half of organizations admitted to being hit by ransomware in the last year at an eye-watering average remediation cost of US$761,106.
Sophos had published the Sophos 2021 Threat Report, which flags how ransomware and fast-changing attacker behaviors, from advanced to entry level, will shape the threat landscape and IT security in 2021.
The report, written by SophosLabs security researchers, as well as Sophos’ threat hunters, rapid responders, and cloud security and AI experts, provides a three-dimensional perspective on security threats and trends, from their inception to real-world impact.
At the high end, the big-game hunting ransomware families will continue to refine and change their tactics, techniques and procedures (TTPs) to become more evasive and nation-state-like in sophistication, targeting larger organizations with multimillion-dollar ransom demands.
Sophos observed that in year 2020, such families included Ryuk and RagnarLocker. At the other end of the spectrum, Sophos anticipates an increase in the number of entry level, apprentice-type attackers looking for menu-driven, ransomware-for-rent, such as Dharma, that allows them to target high volumes of smaller prey.
Another ransomware trend is “secondary extortion,” where alongside the data encryption the attackers steal and threaten to publish sensitive or confidential information, if their demands are not met. In 2020, Sophos reported on Maze, RagnarLocker, Netwalker, REvil, and others using this approach.
Well, one of the most effective methods for protecting against ransomware attacks like Ryuk, Sodinokibi, Maze, and Ragnar Locker is to make use of a properly configured firewall.
