Increased user awareness of phishing threats, better antivirus technology, more industry-wide information sharing and cross-border efforts by law enforcement authorities will combine to turn the tide against ransomware this year, according to some security experts, but others expect the attacks to continue to increase.
According to a security expert who requested anonymity, ransomware cybercriminals took in about $1 billion last year, based on money coming into ransomware-related bitcoin wallets.
That includes more than $50 million each for three wallets associated with the Locky ransomware, and a fourth one that processed close to $70 million. Cryptowall brought in close to $100 million before it was shut down this year. CryptXXX gathered in $73 million during the second half of 2016, and Cerber took in $54 million, the expert said.
