Articles about Ransomware

I recently covered a story in which security firm Imperva said Cryptowall 3.0 was the most successful ransomware of all time, earning its creators $325 million (£225.7m) so far. Now another story about ransomware emerges, and this one comes from another major security firm, Bitdefender.

In its report, the company says almost half (44 percent) of all ransomware victims have paid to get their data back, with 39 percent saying they expect to be attacked again, in the future.

We're only a couple of weeks into a brand new year, and the outlook for security isn't looking particularly better. That doesn't mean you'll be hacked or malware will run wild on your computer, but it does mean you'll still need to be vigilant.

Now the popular Angler exploit kit has a brand new threat contained within it and this one could be especially scary. CryptoWall aims to lock up your files and hold them for ransom, an attack method that has been around now for sometime.

It’s been a busy year for security firms everywhere -- cyber-attacks, malware, ransomware and other malicious online behavior reached new heights in 2015.

Those are the results of a report by Bromium, a company which deals in threat isolation in service of data breach prevention. Its report, entitled Endpoint Exploitation Trends 2015 analyzed the security risks of popular websites and software.

Trend Micro may still be smarting from the revelation that there was a serious vulnerability in its Password Manager tool, but today the security company warns of the dangers of sharing ransomware source code.

The company says that those who discover vulnerabilities need to think carefully about sharing details of their findings with the wider public as there is great potential for this information to be misused, even if it is released for educational purposes. It says that "even with the best intentions, improper disclosure of sensitive information can lead to complicated, and sometimes even troublesome scenarios".

Cross-platform viruses and malware are something of a rarity, but now there's a first-in-its-class JavaScript-based ransomware that can infect Mac, Windows and Linux. Ransom32 uses the Node.js runtime environment running on the NW.js platform to burrow into the target operating system and hold files to ransom.

While on the face of it, this is just another example of ransomware that encrypts files and seeks Bitcoin payments to decrypt them, it is more than that. The NW.js framework not only allows for cross-platform infections, but also means it is harder to detect. Ransom32 bears some resemblance to CryptoLocker and has been dubbed Ransomware-as-a-Service.

Security experts from Panda Security warn that 2016 is set to be a bumper year of attacks and malware infections. The company says that malware will grow at "an exponential rate", with Android, mobile payment platforms, and the Internet of Things being key targets.

Business, individuals, and corporate users alike are at risk, and it is predicted that infections via JavaScript and Windows 10's Powershell are to be common attack vectors. Exploit kits are due to increase in popularity, largely because of the fact that it is not currently easy to combat them.

Crypto-ransomware is one of the latest trends in the world of malware. Encrypting and holding files to ransom provides a way to extort money from victims, but a new example takes things one step further.

Chimera not only locks users out of their files until a ransom is paid, but also threatens to release unencrypted copies of the files online if payment is not made. Security company Trend Micro says this is the first instance of this type of threat. Interestingly, Chimera also seems to be part of an affiliate program.
