Information about the South Korean banks and media systems attacksMarch 20th, 2013 | Posted by in News

The samples use the word “HASTATI” to overwrite the MBR data:
And then shuts down the system using:
shutdown -r -t 0
We have seen that the samples checks for the presence of several security tools:
AhnLab Policy Agent - pasvc.exe
Hauri ViRobot - clisvc.exe
And tries to kill them using taskkill:
taskkill /F /IM pasvc.exe
taskkill /F /IM clisvc.exe

They were originally some of the poorest men in the legion, and could afford only modest equipment—light armour and a large shield, in their service as the lighter infantry of the legion. Later, the hastati contained the younger men rather than just the poorer, though most men of their age were relatively poor. Their usual position was the first battle line. They fought in a quincunx formation, supported by light troops. They were eventually done away with after the Marian reforms of 107 BC”
