The roadmap for a COVID-19 contact-tracing app, to be rolled out by the UK’s National Health Service (NHS), was thrust into the spotlight thanks to sensitive documents being leaked via a public Google Drive link.The state of Utah announcing it has settled on a contact-tracing mobile app that collects detailed user location information to track the spread of COVID-19 among citizens – eschewing the API model proposed by Apple and Google in April.“Double extortion” methods being increasingly used by ransomware actors – and new research that found paying a ransom to unlock systems can actually cost companies more financially than recovering data themselves in the long run.Recent ransomware attacks, including ones targeting healthcare giant Magellan, the IT office that supports Texas appellate courts and judicial agencies, and a popular law firm that works with several A-list celebrities, including Lady Gaga, Drake and Madonna.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.Threatpost editors discuss the top news stories of the week ended May 15, including: '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. The vulnerability, which was unearthed during an internal security audit, resides in an API present in the plugin since version 2.0, which was released in November 2012. 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. WordPress has issued an automatic update to address a critical flaw in the Jetpack plugin thats installed on over five million sites. 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. up to date and safe before granting access to applications. 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. Prolific ransomware gang Clop has claimed credit for the recent wave of MOVEit attacks that have stolen private data from companies around the globe. Cisco Ransomware Defense can prevent and respond to attacks, helping you secure email, web. 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. Ninety-two more apps, nearly half of which are on Google Play, that have cumulatively amassed more than 30 million installations were discovered to be compromised with the SpinOk malware, which. 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." Royal ransomware, which is already one of the most notable ransomware families of 2022, has gained additional notoriety in early May 2023 after it was used to attack IT systems in Dallas, Texas. "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.
