Researchers have disclosed a novel technique by which malware on iOS can achieve persistence on an infected device by faking its shutdown process, making it impossible to physically determine if an iPhone is off or otherwise. The discovery — dubbed "NoReboot" — comes courtesy of mobile security firm ZecOps, which found that it's possible to block and then simulate an iOS rebooting operation,…

VMWare has shipped updates to Workstation, Fusion, and ESXi products to address an "important" security vulnerability that could be weaponized by a threat actor to take control of affected systems. The issue relates to a heap-overflow vulnerability — tracked as CVE-2021-22045 (CVSS score: 7.7) — that, if successfully exploited, results in the execution of arbitrary code. The company credited…

Google has rolled out the first round of updates to its Chrome web browser for 2022 to fix 37 security issues, one of which is rated Critical in severity and could be exploited to pass arbitrary code and gain control over a victim's system. Tracked as CVE-2022-0096, the flaw relates to a use-after-free bug in the Storage component, which could have devastating effects ranging from corruption of…

Cybersecurity researchers have taken the wraps of an organized financial-theft operation undertaken by a discreet actor to target transaction processing systems and siphon funds from entities primarily located in Latin America for at least four years. The malicious hacking group has been codenamed Elephant Beetle by Israeli incident response firm Sygnia, with the intrusions aimed at banks and…

An ongoing ZLoader malware campaign has been uncovered exploiting remote monitoring tools and a nine-year-old flaw concerning Microsoft's digital signature verification to siphon user credentials and sensitive information. Israeli cybersecurity company Check Point Research, which has been tracking the sophisticated infection chain since November 2021, attributed it to a cybercriminal group…

Threat actors leveraged a cloud video hosting service to carry out a supply chain attack on more than 100 real estate websites operated by Sotheby's Realty that involved injecting malicious skimmers to steal sensitive personal information. "The attacker injected the skimmer JavaScript codes into video, so whenever others import the video, their websites get embedded with skimmer codes as well,"…

Microsoft is warning of continuing attempts by nation-state adversaries and commodity attackers to take advantage of security vulnerabilities uncovered in the Log4j open-source logging framework to deploy malware on vulnerable systems. "Exploitation attempts and testing have remained high during the last weeks of December," Microsoft Threat Intelligence Center (MSTIC) said in revised guidance…

A group of academics from the University of California, Santa Barbara, has demonstrated what it calls a "scalable technique" to vet smart contracts and mitigate state-inconsistency bugs, discovering 47 zero-day vulnerabilities on the Ethereum blockchain in the process. Smart contracts are programs stored on the blockchain that are automatically executed when predetermined conditions are met…

A persistent denial-of-service (DoS) vulnerability has been discovered in Apple's iOS mobile operating system that's capable of sending affected devices into a crash or reboot loop upon connecting to an Apple Home-compatible appliance. The behavior, dubbed "doorLock," is trivial in that it can be triggered by simply changing the name of a HomeKit device to a string larger than 500,000 characters…

Trojanized installers of the Telegram messaging application are being used to distribute the Windows-based Purple Fox backdoor on compromised systems. That's according to new research published by Minerva Labs, describing the attack as different from intrusions that typically take advantage of legitimate software for dropping malicious payloads. "This threat actor was able to leave most parts of…
