"The phishing email topics that lead to infestation by ransomware are very specific," McAfee Labs explains. "The email template and attachment names appear not only in the local language but also pretend to be coming from real companies in the targeted countries."Ransomware, some variants of which demand between $150 and $500 for victims to retrieve their encrypted files, has seen an increase despite an international law enforcement effort last year that took down the Gameover ZeuS botnet, which was responsible for helping to spread the CryptoLocker ransomware.
