“The Canadian man who pled guilty last year to a massive spear-phishing operation of Yahoo employees—which ultimately resulted in 500 million accounts being compromised—has been sentenced to five years in prison.”
US Attorney Alex Tse issued a strong statement regarding the case, writing “Hackers such as Baratov ply their trade without regard for the criminal objectives of the people who hire and pay them. These hackers are not minor players; they are a critical tool used by criminals to obtain and exploit personal information illegally. In sentencing Baratov to five years in prison, the Court sent a clear message to hackers that participating in cyber attacks sponsored by nation states will result in significant consequences.”
