Ransomware threats still a major worry for providers

Ransomware is dominating the malware market and has become the most profitable type of malware in history, and healthcare organizations have emerged as the target of choice for cyber criminals.

According to the FBI, ransomware victims paid a total of $209 million in the first quarter of 2016, while the producers of the CryptoWall ransomware attack generated more than $300 million in 2015 alone, according to executives of TrapX Security, which is working on a ransomware defense offering.

Vendors now are offering defense approaches and decryption tools, some at no charge, to help those victimized by ransomware. Here’s a list of vendors and their offerings.

AVG

AVG, an Amsterdam-based online security company, is offering six free tools to decrypt files locked up by ransomware.

AVG’s new free tools are for the decryption of six current ransomware strains: Apocalypse, BadBlock, Crypt888, Legion, SZFLocker, and TeslaCrypt. The page offers guidance in identifying the type of ransomware by the messages appearing on the computer screen.

Cisco Systems

Cisco Systems' Talos team has released a free tool for victims of the TeslaCrypt ransomware attack. The Cisco tool decrypts locked-down files. The tool is aimed at all levels of victims and can be used by those with a variety of expertise levels.

An informational article about the tool to counteract TeslaCrypt can be found here.

Kaspersky Lab

Kaspersky Lab offers its “no ransom” web site to offer a variety of solutions to help organizations afflicted by ransomware. In addition to decryption tools, the site offers “education on ransomware.” The site notes that the malware must be removed first before attempting to decrypt, “otherwise it will repeatedly lock your system or encrypt files.”

The site can be found here.

Decryption tools are available for various ransomware: Shade; Rannoh and variants; Rakhni and variants; and CoinVault and Bitcryptor.

The site also contains a library of additional reading on ransomware.

Minerva Labs

Minerva Labs takes a different tack—it provides an anti-malware solution that prevents targeted attacks without the need for prior detection or other knowledge and before any damage has been done. Minerva's Environment Simulation Technology (EST) creates an environment in which malware refrains from execution. The offering prevents ransomware from execution, by simulating an environment that is unideal for the malware, causing it to refrain from execution.

Ransomware the applications can decrypt include Crypt variants, TeslaCrypt and variants, AutoLocky, BadBlock, and more.

Trend Micro tools include RansomwareFileDecryptor and TeslacryptDecryptor.
