A massive Locky ransomware campaign spotted this month targets primarily the healthcare sector and is delivered in phishing campaigns. The payload, researchers at FireEye said, is dropped via .DOCM attachments, which are macro-enabled Office 2007 Word documents. Especially hard hit are hospitals in the United States followed by Japan, Korea and Thailand, according to research published Wednesday by...
To say the VeraCrypt audit, which begins today, got off to an inauspicious start would be an understatement. On Sunday, two weeks after the announcement that the open source file and disk encryption software would be formally scrutinized for security vulnerabilities, executives at one of the firms funding the audit posted a notice that four...
Researchers claim to have found the largest ransomware-as-a-service (RaaS) ring to date. The operation generates an estimated $2.5 million annually and targets computer users with a new variant of the notorious Cerber ransomware. According to a research report published today by Check Point Software Technologies and IntSights, the RaaS ring consists of 161 active campaigns with...
Academic researchers added another hack to a growing list of compromises involving vehicles, and this one should give drivers pause the next time they leave valuables locked in their trunk. This hack involves millions of Volkswagen, Ford and Chevrolet vehicles that rely on an outdated key fob technology, which creates an opportunity for even an “unskilled adversary”...
LAS VEGAS – There is no guarantee that the internet will succeed. And if we aren’t careful we can really screw it up. It has happened before and we can do it again. The warning comes from technologist Dan Kaminsky who says there is a need to treat the internet similarly to the way the...
LAS VEGAS – The FREAK, LOGJAM and DROWN attacks of the last 17 months weren’t just the work of academics and security researchers who found a cool way to unmask encrypted traffic. They were ugly reminders of the Crypto Wars of the 1990s and why export-grade cryptography and intentional encryption backdoors are fraught with potential...
Google is adding HTTP Strict Transport Security (or HSTS) to the Google.com domain, an extra layer of protection that prevents visitors from using a less secure HTTP connection. By using HSTS, visitors following HTTP links to Google.com will be automatically redirected to the more secure HTTPS version of the Google domain. The effort, announced Friday, is...
LAS VEGAS — Researchers have found flaws in the Web Proxy AutoDiscovery protocol tied to DHCP and DNS servers that allow hackers spy on HTTPS-protected URLs and launch a myriad of different malicious attacks against Linux, Windows or Mac computers. According to the security firm SafeBreach, this vulnerability allows hackers to monitor the URLs of every...
There is no honor among thieves, as the saying goes, and that includes ransomware crooks. In an apparent move to sabotage a ransomware competitor, the authors of the Mischa and Petya ransomware-as-a-service leaked 3,500 decryption keys for its competitor Chimera ransomware. The move appears to be an attempt to push ransomware criminals to ditch Chimera service and...
