Ransomware gang apologizes, provides SickKids hospital free decryptor
The LockBit ransomware gang has launched a free decryptor for the Hospital for Sick Youngsters (SickKids), saying one in all its members violated guidelines by attacking the healthcare group.
SickKids is a instructing and analysis hospital in Toronto that focuses on offering healthcare to sick youngsters.
On December 18th, the hospital suffered a ransomware assault that impacted inner and company techniques, hospital cellphone traces, and the web site.
Whereas the assault solely encrypted just a few techniques, SickKids acknowledged that the incident induced delays in receiving lab and imaging outcomes and resulted in longer affected person wait occasions.
On December twenty ninth, SickKids introduced that it had restored 50% of its precedence techniques, together with these inflicting diagnostic or therapy delays.
LockBit gang apologizes for assault
As first noted by risk intelligence researcher Dominic Alvieri, two days after SickKids’ newest announcement, the LockBit ransomware gang apologized for the assault on the hospital and launched a decryptor without spending a dime.
“We formally apologize for the assault on sikkids.ca and provides again the decryptor without spending a dime, the associate who attacked this hospital violated our guidelines, is blocked and is now not in our associates program,” acknowledged the ransomware gang.

The LockBit operation runs as a Ransomware-as-a-Service, the place the operators preserve the encryptors and web sites, and the operation’s associates, or members, breach victims’ networks, steal knowledge, and encrypt units.
As a part of this association, the LockBit operators preserve roughly 20% of all ransom funds and the remainder goes to the affiliate.
Whereas the ransomware operation permits its associates to encrypt pharmaceutical firms, dentists, and plastic surgeons, it prohibits its associates from encrypting “medical establishments” the place assaults may result in demise.
“It’s forbidden to encrypt establishments the place injury to the information may result in demise, resembling cardiology facilities, neurosurgical departments, maternity hospitals and the like, that’s, these establishments the place surgical procedures on high-tech tools utilizing computer systems could also be carried out,” explains the ransomware operation’s insurance policies.
The stealing of knowledge from any medical establishment is allowed per the insurance policies.
In keeping with the ransomware gang, as one in all its associates encrypted the hospital’s units, they had been faraway from the operation, and a decryptor was supplied without spending a dime.
Nevertheless, this doesn’t clarify why LockBit didn’t present a decryptor sooner, with affected person care being impacted and SickKids working to revive operations because the 18th.
Moreover, LockBit has a historical past of encrypting hospitals and never offering encryptors, as was seen in its assault in opposition to the Heart Hospitalier Sud Francilien (CHSF) in France, the place a $10 million ransom was demanded, and affected person knowledge ultimately leaked.
The assault on the French hospital led to referring sufferers to different medical facilities and suspending surgical procedures, which may have led to vital danger to sufferers.
BleepingComputer had contacted LockBit on the time to grasp why they had been demanding a ransom from CHSF, despite the fact that it was in opposition to insurance policies, however by no means obtained a response.
This isn’t the primary time a ransomware gang has offered a free decryptor to a healthcare group.
In Could 2021, the Conti Ransomware operation offered a free decryptor to Eire’s nationwide well being service, the HSE, after going through elevated strain from worldwide legislation enforcement.
