The Russian state-sponsored threat actor known as  APT28  has been found leveraging a new code execution method that makes use of mouse movement in decoy Microsoft PowerPoint documents to deploy malware. The technique "is designed to be triggered when the user starts the presentation mode and moves the mouse," cybersecurity firm Cluster25  said  in a technical report. "The code execution runs a PowerShell script that downloads and executes a dropper from OneDrive." The dropper, a seemingly harmless image file, functions as a pathway for a follow-on payload, a variant of a malware known as Graphite, which uses the Microsoft Graph API and OneDrive for command-and-control (C2) communications to retrieve additional payloads. The attack employs a lure document that makes use of a template potentially linked to the Organisation for Economic Co-operation and Development ( OECD ), a Paris-based intergovernmental entity. Cluster25 noted the attacks may be ongoing, con...

Meta Platforms on Tuesday disclosed it took steps to dismantle two covert influence operations originating from China and Russia for engaging in coordinated inauthentic behavior (CIB) so as to manipulate public debate. While the Chinese operation sets its sights on the U.S. and the Czech Republic, the Russian network primarily targeted Germany, France, Italy, Ukraine and the U.K. with themes surrounding the ongoing war in Ukraine. "The largest and most complex Russian operation we've disrupted since the war in Ukraine began, it ran a sprawling network of over 60 websites impersonating news organizations, as well as accounts on Facebook, Instagram, YouTube, Telegram, Twitter, Change.org and Avaaz, and even LiveJournal," the social media behemoth  said . The sophisticated Russian activity, which commenced in May 2022, impersonated mainstream European news outlets like Der Spiegel, The Guardian, and Bild, not to mention build credibility by creating fake accounts across...

WhatsApp has released  security updates  to address two flaws in its messaging app for Android and iOS that could lead to remote code execution on vulnerable devices. One of them concerns  CVE-2022-36934  (CVSS score: 9.8), a critical integer overflow vulnerability in WhatsApp that results in the execution of arbitrary code simply by establishing a video call. The issue impacts the WhatsApp and WhatsApp Business for Android and iOS prior to versions 2.22.16.12. Also patched by the Meta-owned messaging platform is an integer underflow bug, which refers to an opposite category of errors that occur when the result of an operation is too small for storing the value within the allocated memory space. The high-severity issue, given the CVE identifier  CVE-2022-27492  (CVSS score: 7.8), affects WhatsApp for Android prior to versions 2.22.16.2 and WhatsApp for iOS version 2.22.15.9, and could be triggered upon receiving a specially crafted video file. Exploi...

The Ukrainian government on Monday warned of "massive cyberattacks" by Russia targeting critical infrastructure facilities located in the country and that of its allies. The attacks are said to be targeting the energy sector, the Main Directorate of Intelligence of the Ministry of Defense of Ukraine (GUR) said. "By the cyberattacks, the enemy will try to increase the effect of missile strikes on electricity supply facilities, primarily in the eastern and southern regions of Ukraine," the agency  said  in a brief advisory. GUR also cautioned of intensified distributed denial-of-service (DDoS) attacks aimed at the critical infrastructure of Ukraine's closest allies, chiefly Poland and the Baltic states of Estonia, Latvia, and Lithuania. It's not immediately clear what prompted the intelligence agency to issue the notice, but Ukraine has been at the receiving end of  disruptive and destructive cyberattacks  since the onset of the Russo-Ukrainian war earli...

Cybercriminals are continuing to prey on users searching for cracked software by directing them to fraudulent websites hosting weaponized installers that deploy malware called  NullMixer  on compromised systems. "When a user extracts and executes NullMixer, it drops a number of malware files to the compromised machine," cybersecurity firm Kaspersky said in a Monday report. "It drops a wide variety of malicious binaries to infect the machine with, such as backdoors, bankers, downloaders, spyware, and many others." Besides siphoning users' credentials, address, credit card data, cryptocurrencies, and even Facebook and Amazon account session cookies, what makes NullMixer insidious is its ability to download dozens of trojans at once, significantly widening the scale of the infections. Attack chains typically start when a user attempts to download cracked software from one of the sites, which leads to a password-protected archive that contains an executable fil...
