As many as 34 unique vulnerable Windows Driver Model (WDM) and Windows Driver Frameworks (WDF) drivers could be exploited by non-privileged threat actors to gain full control of the devices and execute arbitrary code on the underlying systems. “By exploiting the drivers, an attacker without privilege may erase/alter firmware, and/or elevate [operating system] privileges,” Takahiro […]
Threat actors are leveraging access to malware-infected Windows and macOS machines to deliver a proxy server application and use them as exit nodes to reroute proxy requests. According to AT&T Alien Labs, the unnamed company that offers the proxy service operates more than 400,000 proxy exit nodes, although it’s not immediately clear how many of […]
A previously undetected attack method called NoFilter has been found to abuse the Windows Filtering Platform (WFP) to achieve privilege escalation in the Windows operating system. “If an attacker has the ability to execute code with admin privilege and the target is to perform LSASS Shtinkering, these privileges are not enough,” Ron Ben Yizhak, a […]
The Iranian nation-state actor known as TA453 has been linked to a new set of spear-phishing attacks that infect both Windows and macOS operating systems with malware. “TA453 eventually used a variety of cloud hosting providers to deliver a novel infection chain that deploys the newly identified PowerShell backdoor GorjolEcho,” Proofpoint said in a new […]
Microsoft has rolled out fixes for its Windows operating system and other software components to remediate major security shortcomings as part of Patch Tuesday updates for June 2023. Of the 73 flaws, six are rated Critical, 63 are rated Important, two are rated Moderate, and one is rated Low in severity. This also includes three […]
The first Patch Tuesday fixes shipped by Microsoft for 2023 have addressed a total of 98 security flaws, including one bug that the company said is being actively exploited in the wild. 11 of the 98 issues are rated Critical and 87 are rated Important in severity, with one of the vulnerabilities also listed as […]
Government and state-owned organizations in a number of Asian countries have been targeted by a distinct group of espionage hackers as part of an intelligence gathering mission that has been underway since early 2021. “A notable feature of these attacks is that the attackers leveraged a wide range of legitimate software packages in order to […]
The Donot Team threat actor has updated its Jaca Windows malware toolkit with improved capabilities, including a revamped stealer module designed to plunder information from Google Chrome and Mozilla Firefox browsers. The improvements also include a new infection chain that incorporates previously undocumented components to the modular framework, Morphisec researchers Hido Cohen and Arnold Osipov […]
Cybersecurity researchers are drawing attention to an ongoing wave of attacks linked to a threat cluster tracked as Raspberry Robin that’s behind a Windows malware with worm-like capabilities. Describing it as a “persistent” and “spreading” threat, Cybereason said it observed a number of victims in Europe. The infections involve a worm that propagates over removable […]
Cybersecurity researchers have discovered a new Windows malware with worm-like capabilities and is propagated by means of removable USB devices. Attributing the malware to a cluster named “Raspberry Robin,” Red Canary researchers noted that the worm “leverages Windows Installer to reach out to QNAP-associated domains and download a malicious DLL.” The earliest signs of the […]
The Chinese-backed Hafnium hacking group has been linked to a piece of a new malware that’s used to maintain persistence on compromised Windows environments. The threat actor is said to have targeted entities in the telecommunication, internet service provider and data services sectors from August 2021 to February 2022, expanding from the initial victimology patterns […]
Microsoft last week announced that it’s temporarily disabling the MSIX ms-appinstaller protocol handler in Windows following evidence that a security vulnerability in the installer component was exploited by threat actors to deliver malware such as Emotet, TrickBot, and Bazaloader. MSIX, based on a combination of .msi, .appx, App-V and ClickOnce installation technologies, is a universal […]
The U.S. Cybersecurity and Infrastructure Security Agency (CISA) is urging federal agencies to secure their systems against an actively exploited security vulnerability in Windows that could be abused to gain elevated permissions on affected hosts. To that end, the agency has added CVE-2022-21882 (CVSS score: 7.0) to the Known Exploited Vulnerabilities Catalog, necessitating that Federal […]
Cybersecurity researchers have decoded the mechanism by which the versatile Qakbot banking trojan handles the insertion of encrypted configuration data into the Windows Registry. Qakbot, also known as QBot, QuackBot and Pinkslipbot, has been observed in the wild since 2007. Although mainly fashioned as an information-stealing malware, Qakbot has since shifted its goals and acquired […]
A day after releasing Patch Tuesday updates, Microsoft acknowledged yet another remote code execution vulnerability in the Windows Print Spooler component, adding that it’s working to remediate the issue in an upcoming security update. Tracked as CVE-2021-36958 (CVSS score: 7.3), the unpatched flaw is the latest to join a list of bugs collectively known as […]
Short Bytes: The security firm Avecto has just released its security report on Windows operating system. The report outlines an important result stating that 9-out-of-10 Windows security flaws could be mitigated by simply removing a user’s admin rights. Almost nine-out-of-ten Windows operating system vulnerabilities could have been mitigated by removing the admin rights, according to […]
