830,000 machines were compromised by the CryptoWall ransomware worldwide only in the last month. This marks a 25% jump in the infections compared to August 2014. 40,000 victims alone were located in the UK, with 75 from them paying the required fee.

The creators of the fast spreading system-locking malware are using a more aggressive strategy lately, increasing the requested sum. Ransoms between £100 and £1,250 are required, depending on the payment period. Reportedly, the ransom can be raised to as high as £6,250 in case the victim transfers the fee outside the four to seven-day period.

Analysts discovered that the UK was one of the countries with the highest infection rate, followed by Australia with 20, 000 victims, with 66 people paying the fee. The compromised machines in Japan were 2,000, but none of them paid the ransom.

The number of the infected computers in the last nine months is over 600,000, which accounts to a profit of about £ 600,000 for the creators CryptoWall. With a campaign that successful hackers are only expected to improve their malicious techniques, aiming for even higher earnings.

Ransomware has grown into the most aggressive form of cyber-attack lately, applying scare strategies in order to get victims to pay the ransom. Hackers rely on the psychological pressure asserted on the users as a key component in their campaigns. And despite expert‘s warnings not to pay the required fee, more and more victims go for the payment.
