How can you stop ransomware threats from interrupting business continuity and recover quickly when ransomware attacks occur?
Stage 4: Data collection and exfiltration Here the ransomware operators switch focus to identifying valuable data and exfiltrating (stealing) it, usually by downloading or exporting a copy for themselves.
Credential theft Cybercriminals can steal authorized users' credentials, buy them on the dark web, or crack them through brute-force attacks. They then use these credentials to log rein to a network or computer and deploy ransomware directly.
Scareware Scareware is just what it sounds like—ransomware that tries to scare users into paying a ransom. Scareware might Haltung as a message from a law enforcement agency, accusing the victim of a crime and demanding a fine. Alternatively, it might spoof a legitimate virus infection alert, encouraging the victim to purchase ransomware disguised as antivirus software.
