Cybercriminals are always looking for new ways to infect systems - ideally without being noticed until it’s too late. The sky is the limit for their creativity, as the latest wave of malicious boot loaders shows. The kit has been pioneered by Brazilian Trojan bankers who aim to remove security software.
This non-traditional infection only affects systems using ntldr, the default boot loader on Windows NT up to and including Windows XP and Windows Server 2003. This choice was no coincidence - XP is still the most popular OS in several countries, including Brazil, where it runs on nearly 47% of all machines.
