It affects POS systems and is much harder to detect than its original version.

ZD Net explains:

While threats like ransomware might have been making more headlines lately, point of sales (POS) malware is still very much active - mainly targeting retailers and hotel chains, while smaller businesses remain a prime target as they're likely to have even less secure systems.

One of the earliest forms of this type of malware was RawPOS, which has been in operation since 2008. Despite being almost a decade old, RawPOS is still going strong and cybersecurity researchers at Cylance have discovered a new version of it which it said has remained undetected by an unnamed 'legacy antivirus vendor' for over a month.

All that it took for this old form of malware to become undetectable was for the developers behind it to remove some of the code. Rather than adding new features, those behind the malware removed code from the new variant, therefore enabling it to avoid the most common signatures for POS malware.
