Hackers and Ransom Demands – Don’t get caught!
“RansomWeb” is malicious software such as Cryptolocker (now shut down), CryptoDefense, CryptoWall, etc. that enable hackers to take over your computer and change the encryption keys needed to your computer system running.
You wake up one morning to the following message “Your files are encrypted. To regain access to your files you need to pay US $500.00 within seven days, if not paid the demand will increase to US $1500.00.
Your computer will be locked and access to your files, databases, etc. encrypted until you pay their demand.
Recovery takes from several days to weeks, resulting in the loss of critical data.
Typical demands range from US $500.00 to $1500.00, with large organisations often facing demands of $5000 or more.
The latest malware is targets small to medium size businesses and will persistently attack the business through successive email campaigns hoping to catch you when you guard is down.
Law enforcement finds it hard to stop these attacks, even if they identify the source, as attacks usually originate from foreign countries, such as Russia, Eastern Europe and China, where foreign governments are reluctant to cooperate with our law enforcement agencies, such as the AFP.
