The notorious North Korean hacking group Lazarus has added another new malware to its arsenal. Dubbed FudModule, the rootkit exploits a set of five vulnerabilities affecting Dell DBUtil drivers that enables the attackers to deploy several malicious tools on a victim’s system, including droppers, loaders, and backdoors. Meanwhile, accidental exposure of patients’ personal data has been averted after Canon Medical issued patches for two cross-site vulnerabilities affecting its Vitreal View tool. 

There has been a spike in the activities by Bumblebee as researchers observe a new iteration of the malware loader. Active since June, the new version used VHD files to execute PowerShell scripts.
