[SingCERT] Updated Advisory on Ransomware
13 October 2018
Ransomware is a prevalent cyber threat to businesses and individuals. This advisory provides updated information on ransomware and additional measures organisations, businesses and members of public can take to prevent and recover from this threat.
Ransomware is a type of malware that holds a victim’s files, computer system or mobile device ransom, restricting access until a ransom is paid. Some ransomware variants are also known to traverse across the network and encrypt all files stored in shared and/or network drives. By encrypting these files with a strong encryption, these files are rendered irrecoverable unless a decryption key is obtained.
