A spam campaign delivering CTB Locker is targeting employees from French companies, Bitdefender researchers found. The e-mails invite people to open the.cab file, an auto-executable Microsoft archive. The company is urged to pay a ransom to recover the encrypted files, within a short period of time usually 72 hours. Users are advised to be extremely careful when opening e-mail from unknown senders, especially if they carry an attachment. It`s also critical to use an anti-malware solution that proactively protects against threats, and to perform external backup of the company`s data.”]
