CryptoWall Vaccine Updated for the Latest 4.0 Version

2015-11-09 17:30

A few days ago, the first version of CryptoWall 4.0 was spotted in the wild by malware researchers from Bleeping Computer.

The ransomware didn't change too much compared to version 3.0, but it changed enough to cause problems to any detection or prevention systems put out by cyber-security vendors.

One of those systems is Bitdefender's CryptoWall Vaccine, a.k.a. the Bitdefender Anti-Ransomware kit.

Integrating the changes that CryptoWall 4.0 brought forward, the CryptoWall Vaccine can now prevent infections from getting a foothold on target PCs.

As for the CryptoWall Vaccine's efficiency, the name should tell you everything there is to know about it. It's a vaccine, meaning you install it before getting infected, as a way to protect yourself.

Once CryptoWall has already encrypted your files, the only choices at your disposal are either using an older backup to recover some of the files or paying the ransom.

With CryptoWall 3.0 operators making over $325 million in the past year, they will undoubtedly be determined to continue their criminal operations in the upcoming future.

As for the method of infection, CryptoWall 4.0 still relies on phishing campaigns, taking advantage of gullible users. Bitdefender has detected active CryptoWall 4.0 campaigns targeting users in countries like France, Italy, Germany, India, Romania, Spain, US, China, Kenya, South Africa, Kuwait and the Philippines.
