Hackers have turned to ‘fast flux’ techniques to evade security solutions

When law enforcement agencies take down a botnet or a major spam or phishing operation, it usually involves disabling servers and hosting services. To counter these measures, criminals have started turning towards a new technique called “fast flux”.

This is according to a new report from cybersecurity firm Unit 42, which explains that fast flux increases criminal infrastructure resilience by making takedown of their servers and blacklisting of their IP addresses harder.
