Chinese-speaking users are the target of a search engine optimization (SEO) poisoning campaign that uses fake software sites to distribute malware. "The attackers manipulated search rankings with SEO plugins and registered lookalike domains that closely mimicked legitimate software sites," Fortinet FortiGuard Labs researcher Pei Han Liao said . "By using convincing language and small character substitutions, they tricked victims into visiting spoofed pages and downloading malware." The activity, which was discovered by the cybersecurity company in August 2025, leads to the deployment of malware families like HiddenGh0st and Winos (aka ValleyRAT), both of which are variants of a remote access trojan called Gh0st RAT. It's worth noting that the use of Winos has been attributed to a cybercrime group known as Silver Fox , which is also tracked as SwimSnake, The Great Thief of Valley (or Valley Thief), UTG-Q-1000, and Void Arachne. It's believed to be acti...

The U.S. Federal Bureau of Investigation (FBI) has issued a flash alert to release indicators of compromise (IoCs) associated with two cybercriminal groups tracked as UNC6040 and UNC6395 for orchestrating a string of data theft and extortion attacks. "Both groups have recently been observed targeting organizations' Salesforce platforms via different initial access mechanisms," the FBI said . UNC6395 is a threat group that has been attributed a widespread data theft campaign targeting Salesforce instances in August 2025 by exploiting compromised OAuth tokens for the Salesloft Drift application. In an update issued this week, Salesloft said the attack was made possible due to the breach of its GitHub account from March through June 2025. As a result of the breach, Salesloft has isolated the Drift infrastructure and taken the artificial intelligence (AI) chatbot application offline. The company also said it's in the process of implementing new multi-factor auth...

Samsung has released its monthly security updates for Android, including a fix for a security vulnerability that it said has been exploited in zero-day attacks. The vulnerability, CVE-2025-21043 (CVSS score: 8.8), concerns an out-of-bounds write that could result in arbitrary code execution. "Out-of-bounds Write in libimagecodec.quram.so prior to SMR Sep-2025 Release 1 allows remote attackers to execute arbitrary code," Samsung said in an advisory. "The patch fixed the incorrect implementation." According to a 2020 report from Google Project Zero, libimagecodec.quram.so is a closed-source image parsing library developed by Quramsoft that implements support for various image formats. The critical-rated issue, per the South Korean electronics giant, affects Android versions 13, 14, 15, and 16. The vulnerability was privately disclosed to the company on August 13, 2025. Samsung did not share any specifics on how the vulnerability is being exploited in attacks...

Apple has notified users in France of a spyware campaign targeting their devices, according to the Computer Emergency Response Team of France (CERT-FR). The agency said the alerts were sent out on September 3, 2025, making it the fourth time this year that Apple has notified citizens in the county that at least one of the devices linked to their iCloud accounts may have been compromised as part of highly-targeted attacks. The agency did not share further details on what triggered these alerts. Previous threat notifications were sent on March 5, April 29 , and June 25. Apple has been sending these notices since November 2021. "These complex attacks target individuals for their status or function: journalists, lawyers, activists, politicians, senior officials, members of steering committees of strategic sectors, etc," CERT-FR said. The development comes less than a month after it emerged that a security flaw in WhatsApp ( CVE-2025-55177 , CVSS score: 5.4) was chained wi...

Cybersecurity researchers have discovered a new ransomware strain dubbed HybridPetya that resembles the notorious Petya / NotPetya malware, while also incorporating the ability to bypass the Secure Boot mechanism in Unified Extensible Firmware Interface (UEFI) systems using a now-patched vulnerability disclosed earlier this year. Slovakian cybersecurity company ESET said the samples were uploaded to the VirusTotal platform in February 2025. "HybridPetya encrypts the Master File Table , which contains important metadata about all the files on NTFS-formatted partitions," security researcher Martin Smolár said . "Unlike the original Petya/NotPetya, HybridPetya can compromise modern UEFI-based systems by installing a malicious EFI application onto the EFI System Partition." In other words, the deployed UEFI application is the central component that takes care of encrypting the Master File Table (MFT) file, which contains metadata related to all the files on the NTF...
