The LockBit ransomware operation has once again taken center stage in the ransomware news, as we learned yesterday they were behind the attack on Royal Mail.
Royal Mail is the UK’s largest mail delivery service and is considered critical infrastructure in the country, with disruption to its services having a significant impact on the country’s economy and supply chain.
Wednesday, Royal Mail suffered a cyberattack which led to the cessation of international maritime services.
Yesterday we learned that this disruption was caused by a LockBit ransomware attack which encrypted the computers used to print the customs slips needed for international shipping.
LockBit having become the largest ransomware operation, it also seems to have become very heavy-handed, with affiliates targeting critical infrastructure and children’s hospitals, even though this goes against gang policies.
LockBit has finally released a free decryptor for SickKids children’s hospital but it is unclear if they will for Royal Mail at this time.
We also learned this week that Operation Vice Society Ransomware attacked and leaked data from Fire Rescue Victoriaa large fire and rescue service in Australia.
New ransomware research has also been leaked or discovered, with various reports listed below:
CISA now requires federal agencies to patch OWASSRF flaw by the end of January due to its active exploitation by the Cuba and Play ransomware operations.
