Security News > 2021 > February > Underwriters Laboratories (UL) certification giant hit by ransomware
UL LLC, better known as Underwriters Laboratories, has suffered a ransomware attack that encrypted its servers and caused them to shut down systems while they recover.
BleepingComputer has learned that UL suffered a ransomware attack last weekend that encrypted devices in their data center.
According to a source familiar with the attack, UL has decided not to pay the ransom and is restoring from backups instead. As it takes time to restore devices, the attack has led to the myUL client portal remaining offline while they recover.
In a statement to BleepingComputer, UL confirmed that the attack occurred on February 13th and is currently investigating the attack.
"Until we learn more from our investigation, we cannot speculate as to the type of information that may be potentially impacted. If we determine that data is impacted, we will take appropriate actions" - UL LLC. It is unknown what ransomware operation conducted the attack and whether they stole unencrypted files.
As most enterprise-targeting ransomware operations steal unencrypted files to be used in a double-extortion strategy, the ransomware gang likely stole data during the attack.
