Ransomware-as-a-service group LockBit is responsible for a cyber incident that continues to impede the delivery of international mail from the United Kingdom, Britain’s The Telegraph newspaper reported.
Britain’s national postal service, Royal Mail, first advised customers Wednesday of a digital incident disrupting international export services, an outage that continued into Thursday. “Please do not post any export items while we work to resolve the issue,” the postal carrier tweeted.
Sources identified as “familiar with the investigation” told the The Telegraph the cause of the incident is LockBit ransomware. It infected machines used to print customs labels for parcels being sent to overseas destinations, the newspaper reported.
The Belfast Telegraph reported that at a Royal Mail facility in Northern Ireland, ransom notes were being churned out by printing machines on Tuesday.
Royal Mail did not immediately respond to a request for comment. The postal carrier alerted the U.K’s National Cyber Security Center and National Crime Agency. Neither agency provided further details regarding the hack.
