British Royal Mail, which suffered a cyber attack last week that temporarily stopped sending parcels and letters outside the country, claims that the personal data of its customers was not compromised during the hack.

Royal Mail CEO Simon Thompson told the British House of Commons on Tuesday that no data breach had occurred, according to an investigation, although the UK Information Commissioner's Office, which regulates data privacy, had been made aware of the incident.

“If this situation changes, then we will of course inform clients and authorities immediately,” Thompson told MPs. He added that the company was warned that discussing even minor or additional details regarding the incident could harm the investigation.

According to Thompson, we should expect news about this in the near future, which suggests the possibility of resuming international mail.

Behind the cyber attack on the Royal Mail is the LockBit hacker group, which, using a ransomware virus, blocks the operation of computer networks and demands a ransom for unlocking them.
