If a file with a suspicious extension is detected, the synchronization immediately stops. How does ASUS WebStorage Sync protect your files from ransomware?īy regularly syncing important files to the cloud, ASUS WebStorage Sync can help safeguard against ransomware. Attackers then demand payment to unlock your files. Once your PC is infected, ransomware renames your files with a new extension and encrypts them. Cyber attackers use various methods to spread malware, including infected links or email attachments. While Apple quickly revoked the signature of the infected version of Transmission, preventing most users from infecting themselves with KeRanger, an estimated 6,500 users may have downloaded the compromised app.Ransomware is a type of malicious software that takes control of your computer and denies you access to it. 'I would love to find some new ransomware'Īpple's built-in defenses are often not so sophisticated, as Wardle has noted in the past. Indeed, the idea of detecting malware by its behavior rather than by its appearance (comparing a file to known virus signatures) is not brand new - some antivirus companies have already implemented versions of this "heuristic analysis" into their efforts to fight ransomware. Wardle is quick to point out that the ideas behind RansomWhere? might not be entirely novel. While Business Insider was not able to test RansomWhere? against a real virus (all of our Macs have the latest security updates, so we wouldn't be able to run a virus at all), Wardle claims that, in his testing, the app successfully blocked both of the existing ransomware viruses that he had access to. If all these boxes are checked, it pauses the suspicious process and alerts the user, letting them decide whether to allow it to continue or stop it in its tracks. It then assesses whether the file was encrypted (in a process outlined in Wardle's explanatory blog post) and whether the process that made it also looks to be encrypting other files. RansomWhere? runs in the background, watching for the creation of new files by any new or untrusted applications. When RansomWhere? is run for the first time, it prompts the user to install it so that it can monitor file changes in the background. After about a month of working on the project in his spare time, he released RansomWhere? 1.0.0 on Wednesday. The goal is to detect ransomware by looking for suspicious encryption activity instead. So Wardle got to work on a tool to detect - and stop - ransomware generically, meaning that it wouldn't have to rely on a list of previously-known viruses which can quickly become outdated. ![]() "This is just going to be an ongoing process for the foreseeable future, even for Mac users." "There's so much money to be made for hackers," he said. ![]() While Apple soon updated its built-in virus protection and Transmission removed the infected downloads from its site, Wardle was confident that the problem wasn't going anywhere. Wardle said that he could see this type of infection happening to him and wanted to do something about it. "Even if they're best security practices - they haven't turned off Gatekeeper, they're not downloading shady apps from random sites - they still would have gotten infected." "From a user's point of view, it really sucks," Wardle said in an interview with Business Insider on Wednesday. Account icon An icon in the shape of a person's head and shoulders.
