Best of all, the additional features are only slightly delayed.
Academic researchers have developed a novel idea to thwart extortion virus attacks using firmware that can block write access to solid state disks (SSDs) as soon as it detects patterns that are appropriate for such an attack.
The idea for a smart firmware called SSD-Insider was proposed by a research team of Korean and American computer scientists. “I thought it would be good if we could protect people who don’t have anti-conversion software installed on their computer with an internal anti-conversion SSD,” one of them, DaeHun Nyang, told The Registry .
The researchers explained their idea in a study on SSD-Insider , SSD-Assisted Ransomware Recognition and Data Recovery Techniques . Analyzing the study, The Register explains that SSD-Insider , which runs on the SSD controller, keeps its eyes open for patterns of drive activity that correspond to blackmail attacks.
As soon as malicious activity is detected, the mechanism disables input and output to the storage device, allowing users to remove the attacking process that initiated the encryption. SSD-Insider is also reported to reverse data corruption in seconds because it Utilizing the operational features of an SSD, it immediately restores infected files.
According to researchers, SSD-Insider has been 100 percent successful against both “wild-type” and laboratory-created pests, and has even been able to reverse damage within ten seconds. Best of all , due to the implementation on the firmware, the mechanism results in a delay of only 12.8-17.3 percent, and the reduction in transmission speed is up to 8 percent. volt.
