A massive Magniber ransomware campaign is underway, encrypting home users' devices worldwide and demanding thousand-dollar ransoms to receive a decryptor.

Magniber launched in 2017 as a successor to the Cerber ransomware operation when it was spotted being distributed by the Magnitude exploit kit.

Since then, the ransomware operation has seen bursts of activity over the years, with the threat actors utilizing various methods to distribute Magniber and encrypt devices. These tactics include using Windows zero-days, fake Windows and browser updates, and trojanized software cracks and key generators.
