Irish authorities have been assessing leaked material believed to be linked to Russian hacking group Conti, the cyber criminals behind last year’s ransomware attack on the HSE.
Internal chat records from the criminal gang have been leaked online by someone reported to be a Ukrainian cybersecurity researcher.
Ireland’s National Cyber Security Centre says it has carried out an assessment of the leaked files.
“The NCSC is aware of the material released recently which purports to relate to one of the threat actor groups associated with the HSE incident last year,” according to a spokesperson for the Department of the Environment, Climate and Communications.
“The NCSC had immediate access to professional translations of the text and has conducted an assessment of the content and its implications for the threat landscape in Ireland,” the spokesperson added.
“While this material appears to offer an insight into the dynamics within ‘Ransomware as a Service’ consortia, there is little in this of which the NCSC or the broader cyber security community were not already aware,” according to the spokesperson.
An Garda Síochána says that while it does not comment on ongoing investigations, it is aware of certain material that has recently come into the public domain that may relate to the Conti ransomware group.
“An Garda Síochána continue to assess all information in respect of any matters under investigation,” according to a Garda statement.
The NCSC says it is currently operating at a heightened state of preparedness, in response to recent cyber incidents and the tensions in eastern Europe.
“While the NCSC has assessed that the potential direct risk of attack to Ireland is low, there is a moderate to high risk that second or third order effects of cyber action elsewhere could have a knock-on effect in Ireland,” according to a spokesperson.
Last month, new figures revealed that the cost of the response to, and recovery from the HSE cyber-attack has reached almost €43 million and could rise to €100m.
The figures were released to the Aontú leader Peadar Tóibín on foot of a parliamentary question to the Department of Health.
