Some ransomware viruses are strategically designed to cause as much damage as possible while producing large profits for cybercriminals. And the ransom demands for these Advanced Ransomware Threats (ARTs) far exceed those for a typical ransomware attack. ARTs hold your most valuable assets for ransom and ensure that copies of the data are not available for restoration. There are typically six phases of an ART attack, including: Reconnaissance This process begins with reconnaissance. The attacker reviews information on the company and may even make a list of employees mentioned on the company…

Most people will never have a fire in their home or office, but everyone can remember going through a fire drill at some point. The process of evacuating a building and meeting outside prepares us for the actual conditions we might face in a real fire. Many companies go to great lengths to prepare for disasters like fires and floods, but most remain woefully unprepared to deal with ransomware—despite the fact that ransomware attacks are far more likely. One way to improve your company’s ransomware incident response capability is to gather your employees…

A new malware do-it-yourself kit called Karmen is making it easy for wannabe cybercriminals to launch ransomware attacks. Security researchers believe the recently discovered ransomware as a service (RaaS) offering was developed in part by a Russian-speaking ransomware author who goes by the alias DevBitox. For a price, Karmen can turn almost anyone into a cybercriminal in just a few clicks.   RaaS offerings like Karmen began popping up on the dark web in 2015 and ransomware developers have continued to make the kits more user-friendly over time. Karmen is…

There are a variety of different ransomware variants that encrypt your data with no intention of ever decrypting it. There are also ransomware distributors who are happy to collect ransom payments but have no interest in returning anyone’s data. Innocent victims often fall prey to ransomware hoaxes or find problems with ransomware decryptors. They all end up in the same place they started, without their valuable data. Some of the groups behind the most prevalent ransomware viruses are working to build up confidence that victims will receive their data if…

When it comes to ransomware attacks, those who lose valuable data and have no viable backup tend to pay the ransom, while those with backups simply restore their data. However, neither group walks away unscathed because they both suffer downtime. Downtime is the period when systems are unavailable for use, and it can cost small and midsize businesses thousands of dollars or worse—it could put them out of business. An Imperva survey of RSA 2017 attendees found that downtime costs companies more than $5,000 in 56% of cases and more…

Spora is a relatively new ransomware, but there are signs which indicate that it could become a major player in the underground ransomware market, according to various reports. There are currently hundreds of ransomware variants being used by cybercriminals, but only a handful are backed by major criminal syndicates that have the funding to write robust malicious code and the infrastructure to support global extortion efforts. These groups are behind some of the biggest names in ransomware like Locky, CryptoLocker and TeslaCrypt. Spora is not there yet, but it’s certainly…

Cybercriminals extorted about one billion dollars from ransomware victims last year, according to the FBI. And nearly all of those perpetrators went unprosecuted because of the innovative methods they use to protect their identities and hide their funds. They go to great lengths to keep authorities from seizing or freezing their money. By and large, their efforts have paid off. Here’s how they do it: Hidden identities, disposable email Extortionists protect their identities whenever interacting with victims. This generally occurs when they distribute ransomware, and when they collect ransom payments…
