    Ransomware Security Advisory – May 2021
    Since the start of 2021 we have witnessed an increase in Ransomware activities in Ireland in particular targeted “double exploit” campaigns. Of note are the Ryuk and Conti variants. Conti being a newer more advanced version of Ryuk. The Ryuk variant has been used in attacks on 3rd level institutions. The Conti variant has been used in the recent HSE and Department of Health attacks. Although these attacks have highlighted the threat of Ransomware it should be stressed that Ransomware represents an ongoing threat. It is believed that the same threat actor group WIZARD SPIDER are responsible for Ryuk and Conti based attacks. In 2019 this group was able to extort approximately $60 million in bitcoin. Other Ransomware variants of note are Sodinokibi and Lockbit.
