Researchers have identified a new family of ransomware that attacks Android devices, locking up files and demanding payment in exchange for a decryption key, ZDNet reported this week. The new malware is called Android/Filecoder.C, and it is spread through malicious posts found on popular forums such as Reddit. The post pretends to offer adult content, but when a victim clicks on the malicious link, Filecoder automatically downloads to his or her device.
