.” The NCSC also provided info about the initial infection vectors observed in the ransomware attacks: Insecure Remote Desktop Protocol (RDP) configurations Vulnerable Software or Hardware Phishing emails. backup servers, network shares, servers, auditing devices). PowerShell) to easily deploy tooling or ransomware.
Pre-Installed Malware In Firmware Because the malware is "baked into" the firmware, it's no easy feat to remove the malware, or even possible. Malware (or users clicking on phishing sites) get by existing defenses on a regular basis. Though I personally wouldn't like my devices being used for click-fraud either.
