Researchers have discovered what is believed to be the first case of ransomware using a sophisticated technique called Doppelgänging to avoid detection by antivirus solutions.
Security experts from Kaspersky Lab said in a security notice that a variant of the SynAck ransomware has been spotted in the wild using this sophisticated circumvention technique.
SynAck is nothing new. The ransomware was discovered in 2017 and differs from standard ransomware families in several ways. While SynAck employs the standard recipe of infection, encryption, and a blackmail notice demanding money in return for a decryption key, the ransomware does not use a payment portal.
