A security researcher, Victor Gevers, and the GDI foundation told the attacks were being tracked for years and that these recent ransoms appear to be the work of a sophisticated cyber attacker. Victor Gevers also added that the group of hackers targeted old Lenovo devices that were already wide open on the internet, allowing the hackers not to rely on a complex exploit when encrypting the data.
If a ransom note is not paid within five days, the Cl0ud SecuritY threatened to leak the files that they claimed to have been copied and sent to their servers. But, the report said that there is no evidence yet showing that any data from the past victims have been leaked online, nor has been backed up anywhere for the past year. The report also suggested that the role of the attack is to lure victims into paying a ransom demand for data hackers have already wiped since the ransom notes appear to carry empty threats, based on current evidence.
