CPU resource occupied by processes such as dhcp.pid, minerd, synodns, PWNED, PWNEDb, PWNEDg, PWNEDm, or any processes with PWNED in their namesAppearance of non-Synology folder:
An automatically created shared folder with the name ¡°startup¡±, or a non-Synology folder appearing under the path of ¡°/root/PWNED¡±Redirection of the Web Station:
¡°Index.php¡± is redirected to an unexpected pageAppearance of non-Synology CGI program:
Files with meaningless names exist under the path of ¡°/usr/syno/synoman¡±Appearance of non-Synology script file:
Non-Synology script files, such as?¡°S99p.sh¡±, appear under the path of ¡°/usr/syno/etc/rc.d¡±

If users identify any of above situation, they are strongly encouraged to do the following:

For DiskStation or RackStation running on DSM 4.3, please follow the instruction?here?to REINSTALL?DSM 4.3-3827For DiskStation or RackStation running on DSM 4.0, it¡¯s recommended to REINSTALL DSM 4.0-2259 or onward from Synology?Download CenterFor DiskStation or RackStation running on DSM 4.1 or DSM 4.2, it¡¯s recommended to REINSTALL DSM 4.2-3243 or onward from Synology?Download Center

For other users who haven¡¯t encountered above symptoms, it is recommended to go to
DSM > Control Panel > DSM Update?page, update to versions above to protect DiskStation from malicious attacks.

Synology has taken immediate actions to fix vulnerability at the point of identifying malicious attacks.
