Recently, The Financial Times reported that Asian subsidiaries of a French Global insurance company were hit by a latest ransomware attack known as Avaddon. Attackers seized 3TB of data, impacting IT operations in Thailand, Malaysia, Hong Kong and the Philippines, taking hold of sensitive information like medical records and hospital data.

What is Avaddon ransomware and how does it work? 

Avaddon first uses phishing emails to infect victims’ endpoints before making its way through the network, encrypting files and exfiltrating valuable data. What is particularly interesting about this ransomware is the method it utilises to delete backups – not only does the ransomware remove shadow copies of the user’s files, it also deletes system backups, disables automatic repair and recovery, and clears the bin. Attackers have also made use of a double extortion method post-hit by threatening to leak victims’ data publicly if payment was not received.

Online threat analysis repository VirusTotal noted that the first submission of Avaddon was recorded in June 2020, yet we do see the ransomware claiming its latest victim (publicly) even as presently as May 2021. Even as the threat becomes more mainstream over time, it is hard to imagine that any Endpoint Protection/Antivirus vendor would have all the threat signatures necessary to safeguard against all threats simply via a signature-based approach.

Modern problems require modern solutions

What organizations need is a behavioural solution to detect and stop zero-day and unknown threats. In the modern threat landscape, it is crucial for users to adopt cyber technologies that can detect and block sophisticated and unknown threats – ranging from ransomware to fileless and in-memory attacks. These solutions should also provide proactive threat hunting capabilities to enable the discovery of hidden threats within one’s infrastructure. With traditional protection methods, visibility is poor, and chances of compromise are heightened.

By leveraging unprecedented levels of automation using AI and ML, ReaQta autonomously detects the ransomware’s behaviour and actively mitigates threats as they unfold.

Attack information is also delivered in accordance with the MITRE ATT&CK cyber kill chain to easily allow analysts to understand the current stage of a compromise.

Avaddon is automatically stopped by ReaQta-Hive EDR within seconds.

With ReaQta’s real-time protection capabilities, threats like ransomware are automatically detected and stopped, preventing organisations from becoming the next victim of a ransomware attack. In the case of Avaddon, ReaQta was effective within seconds, effectively mitigating hits that would have otherwise led to costly reputational damages and data exfiltration. Aside from just stopping the threat, ReaQta’s AI automatically terminates all malicious processes involved in the incident, thereafter closing off the alert, reducing extra actions needed to be taken by the security team.
