Ransomware is guilty for the closure of all 175 7-Eleven shops in Denmark on Monday.
The retailer closed all of its shops in Denmark after its money registers and fee techniques had been introduced down within the assault.
Initially, 7-Eleven’s Danish division didn’t say that ransomware was chargeable for its issues, merely describing the incident as a “hacker assault”:
“We suspect that we have now been the sufferer of a hacker assault at present. We are able to’t use the money registers nor settle for funds. We’re due to this fact closed till we all know the extent of the assault.”
Jesper Østergaard, the CEO of 7-Eleven Denmark informed an area TV station that the primary indication that the corporate had been focused by hackers got here when employees reported that they had been unable to course of funds:
“The money registers simply stopped working in all of the shops and the staff began letting us know. That has by no means occurred earlier than.”
As Bleeping Laptop stories, the corporate has since confirmed that it was focused by a ransomware assault, and that it’s working with police investigators. Lots of 7-Eleven’s shops in Denmark have since reopened.
7-Eleven Denmark is just not sharing a lot in the best way of technical element concerning the assault, which implies that not solely can we not know what household of ransomware might need brought on the disruption however we additionally have no idea the way it might need entered the organisation within the first place.
As an example, is it attainable that all the nation’s 7-Eleven shops had been seemingly impacted concurrently as a result of they had been all reliant on the identical know-how – maybe supplied by a provider who may themselves have been compromised?
As well as, there is no such thing as a public phrase – as but – about whether or not the attackers have made any ransom calls for, and what 7-Eleven’s place is on whether or not it could be ready to pay its extortionists or not.
One piece of fine information is that the assault seems to have been restricted simply to 7-Eleven’s Danish shops, relatively than spreading additional afield. As one Twitter person commented, different organisations may be taught from this invaluable lesson concerning the worth of community segmentation.
7-Eleven is just not the primary retailer to have discovered itself with closed shops following a ransomware assault.
Late final yr, for example, the UK grocery store chain Spar had its checkouts disabled at over 300 branches.
Earlier within the yr, in separate assaults, Swedish branches of Coop had been compelled to close after being hit, and an assault on a Dutch grocery store chain truly resulted in a cheese scarcity.
