Facebook may be banned in China, but the company on Wednesday said it has disrupted a network of bad actors using its platform to target the Uyghur community and lure them into downloading malicious software that would allow surveillance of their devices. "They targeted activists, journalists and dissidents predominantly among Uyghurs from Xinjiang in China primarily living abroad in Turkey, Kazakhstan, the United States, Syria, Australia, Canada and other countries," Facebook's Head of Cyber Espionage Investigations, Mike Dvilyanski, and Head of Security Policy, Nathaniel Gleicher,  said . "This group used various cyber espionage tactics to identify its targets and infect their devices with malware to enable surveillance." The social media giant said the "well-resourced and persistent operation" aligned with a threat actor known as  Evil Eye  (or Earth Empusa), a China-based collective known for its history of espionage attacks against the Muslim m...

Purple Fox , a Windows malware previously known for infecting machines by using exploit kits and phishing emails, has now added a new technique to its arsenal that gives it worm-like propagation capabilities. The ongoing campaign makes use of a "novel spreading technique via indiscriminate port scanning and exploitation of exposed SMB services with weak passwords and hashes," according to  Guardicore researchers , who say the attacks have spiked by about 600% since May 2020. A total of 90,000 incidents have been spotted through the rest of 2020 and the beginning of 2021. First discovered in March 2018, Purple Fox is distributed in the form of malicious ".msi" payloads hosted on nearly 2,000 compromised Windows servers that, in turn, download and execute a component with  rootkit capabilities , which enables the threat actors to hide the malware on the machine and make it easy to evade detection. Guardicore says Purple Fox hasn't changed much post-exploitat...

The U.S. Cybersecurity and Infrastructure Security Agency (CISA) has warned of critical security shortcomings in GE's Universal Relay (UR) family of power management devices. "Successful exploitation of these vulnerabilities could allow an attacker to access sensitive information, reboot the UR, gain privileged access, or cause a denial-of-service condition," the agency said in an advisory published on March 16. GE's universal relays enable  integrated monitoring and metering, high-speed communications, and offer simplified power management for the protection of critical assets. The flaws, which affect a number of UR advanced protection and control relays, including B30, B90, C30, C60, C70, C95, D30, D60, F35, F60, G30, G60, L30, L60, L90, M60, N60, T35 and T60, were addressed by GE with the release of an updated version of the UR firmware (version 8.10) made available on December 24, 2020. The patches resolve a total of nine vulnerabilities, the most importan...

Google has disclosed that a now-patched vulnerability affecting Android devices that use Qualcomm chipsets is being weaponized by adversaries to launch targeted attacks. Tracked as CVE-2020-11261 (CVSS score 8.4), the flaw concerns an "improper input validation" issue in Qualcomm's Graphics component that could be exploited to trigger memory corruption when an attacker-engineered app requests access to a huge chunk of the device's memory. "There are indications that CVE-2020-11261 may be under limited, targeted exploitation," the search giant said in an updated January security bulletin on March 18. CVE-2020-11261 was discovered and reported to Qualcomm by Google's Android Security team on July 20, 2020, after which it was fixed in January 2021. It's worth noting that the access vector for the vulnerability is "local," meaning that exploitation requires local access to the device. In other words, to launch a successful attack, the...

Cybersecurity researchers on Sunday disclosed multiple critical vulnerabilities in remote student monitoring software Netop Vision Pro  that a malicious attacker could abuse to execute arbitrary code and take over Windows computers. "These findings allow for elevation of privileges and ultimately remote code execution which could be used by a malicious attacker within the same network to gain full control over students' computers," the McAfee Labs Advanced Threat Research team said in an analysis. The vulnerabilities, tracked as CVE-2021-27192, CVE-2021-27193, CVE-2021-27194, and CVE-2021-27195, were reported to Netop on December 11, 2020, after which the Denmark-based company fixed the issues in an update (version 9.7.2) released on February 25. "Version 9.7.2 of Vision and Vision Pro is a maintenance release that addresses several vulnerabilities, such as escalating local privileges sending sensitive information in plain text," the company stated in its ...
