LONDON Britain's Royal Mail said on Wednesday it had begun moving limited volumes of export parcels as it trials operational workarounds after a cyber incident severely disrupted its international export services last week.
The postal company, part of International Distributions Services Plc, said it had resumed exports of letters and from 1900 GMT customers could begin submitting international export letters to its network.
It said while it trials the workarounds, it was still asking customers not to submit new export parcels. Import operations and domestic services are unaffected.
The Royal Mail said in a statement that the initial focus will be to clear mail that has already been processed and is waiting to be dispatched.
Royal Mail, one of the world's largest post and parcel firms, said it was working with external experts, security authorities and regulators to mitigate the impact of the incident.
Last week, the Telegraph reported that Lockbit, a ransomware group that some cybersecurity experts say has members in Russia, was behind the incident. Royal Mail didn't want to comment on the report.
In recent years, the number of ransomware incidents - where hackers encrypt victims' data with software and offer them a key in return for money - has risen sharply.
