Google has released a critical security update for its Chrome browser to address a high-severity zero-day vulnerability, identified as CVE-2025-2783. This vulnerability was actively exploited in a sophisticated espionage campaign targeting Russian organizations, specifically media companies, educational institutions, and government entities. According to Kaspersky, the vulnerability allowed attackers to bypass Chrome’s sandbox protections, gaining unauthorized access to affected systems without requiring further user interaction. This incident marks the first actively exploited Chrome zero-day since the start of the year, underscoring the persistent threat landscape faced by internet users.
Kaspersky's investigation, dubbed "Operation ForumTroll," revealed that the attacks were initiated through personalized phishing emails disguised as invitations to the "Primakov Readings" forum. Clicking the malicious link led victims to a compromised website that immediately exploited the zero-day vulnerability. The technical sophistication of the exploit chain points to a highly skilled Advanced Persistent Threat (APT) group. Google urges users to update their Chrome browsers immediately to version 134.0.6998.177/.178 for Windows to mitigate the risk.

The FBI has issued a warning about the rising trend of cybercriminals using fake file converter tools to distribute malware. These tools, often advertised as free online document converters, are designed to trick users into downloading malicious software onto their computers. While these tools may perform the advertised file conversion, they also secretly install malware that can lead to identity theft, ransomware attacks, and the compromise of sensitive data.
The threat actors exploit various file converter or downloader tools, enticing users with promises of converting files from one format to another, such as .doc to .pdf, or combining multiple files. The malicious code, disguised as a file conversion utility, can scrape uploaded files for personal identifying information, including social security numbers, banking information, and cryptocurrency wallet addresses. The FBI advises users to be cautious of such tools and report any instances of this scam to protect their assets.
The FBI Denver Field Office is warning that they are increasingly seeing scams involving free online document converter tools and encourages victims to report any instances of this scam. Malwarebytes has identified some of these suspect file converters, which include Imageconvertors.com, convertitoremp3.it, convertisseurs-pdf.com and convertscloud.com. The agency emphasized the importance of educating individuals about these threats to prevent them from falling victim to these scams.

A new sophisticated Phishing-as-a-Service (PhaaS) platform, dubbed "Morphing Meerkat," is exploiting DNS MX records to dynamically deliver tailored phishing pages, targeting over 100 brands. This operation enables both technical and non-technical cybercriminals to launch targeted attacks, bypassing security systems through the exploitation of open redirects on adtech servers and compromised WordPress websites. The platform's primary attack vector involves mass spam delivery and dynamic content tailoring, evading traditional security measures.
Researchers have discovered that Morphing Meerkat queries DNS MX records using Cloudflare DoH or Google Public DNS to customize fake login pages based on the victim's email service provider. This technique allows the platform to map these records to corresponding phishing HTML files, featuring over 114 unique brand designs. This personalized phishing experience significantly increases the likelihood of successful credential theft. The phishing kit also uses code obfuscation and anti-analysis measures to hinder detection, supporting over a dozen languages to target users globally.

North Korea-linked APT group ScarCruft has been identified deploying a new Android spyware dubbed KoSpy, targeting Korean and English-speaking users. The spyware was distributed through fake utility apps on the Google Play Store and third-party app stores like APKPure. At least five malicious applications, masquerading as File Manager, Phone Manager, Smart Manager, Software Update Utility, and Kakao Security, were used to trick users into installing the spyware onto their devices.
The malicious apps offer the promised functionality to avoid raising suspicion while stealthily deploying spyware-related components in the background. The spyware is designed to collect a wide range of data from compromised devices, including SMS messages, call logs, device location, files in local storage, screenshots, keystrokes, Wi-Fi network information, and the list of installed applications. It's also equipped to record audio and take photos. The apps have since been removed from the app marketplace.

A resurgence of a fake CAPTCHA malware campaign has been observed, with threat actors compromising widely used websites across various industries. They are embedding a fake CAPTCHA challenge that redirects victims to a site triggering PowerShell code execution. This campaign exploits social engineering tactics and fake software downloads to deceive users into executing malicious scripts.
This tactic is also utilized with fake captchas which resemble legitimate sites. When users attempt to pass the captcha, they are prompted to execute code that has been copied to their clipboard. The OBSCURE#BAT malware campaign is a major cybersecurity threat to both individuals and organizations, primarily due to its ability to compromise sensitive data through advanced evasion techniques, including API hooking. This allows the malware to hide files and registry entries, making detection difficult.

Cybercriminals are actively targeting SEO professionals through a sophisticated phishing campaign that exploits Google Ads. The attackers are using fake Semrush advertisements to trick users into visiting deceptive login pages designed to steal their Google account credentials. This campaign is a new twist in phishing, going after users of the Semrush SaaS platform, which is popular among SEO professionals and businesses, and is trusted by 40% of Fortune 500 companies.
This scheme is effective due to the SEO professionals' trust in Semrush, a platform used for advertising and market research. The malicious ads appear when users search for Semrush and redirect them to counterfeit login pages, which look similar to legitimate Semrush URLs. The attackers register domain names that closely resemble real Semrush domains and the only login option is with a Google account, harvesting Google account information for further malicious activities. This provides the attackers with valuable access to Google Analytics and Google Search Console, giving them insight into the companies' financial performance.

A recent cybersecurity investigation has uncovered a cluster of 16 malicious Chrome extensions that have compromised at least 3.2 million users. These extensions, which include functionalities like screen capture, ad blocking, and emoji keyboards, were found to inject code into browsers, facilitating advertising and search engine optimization fraud. GitLab's security team discovered these extensions on the official Google Web Store and were used to insert ads and manipulate search engine results.
The malicious extensions operate by checking in with unique configuration servers, transmitting extension versions and hardcoded IDs, and storing configuration data locally. They also create alarms to refresh this data periodically and degrade browser security by stripping Content Security Policy (CSP) protections. Following the discovery, Google was notified, and all identified extensions have been removed from the Chrome Web Store. However, users must manually uninstall these extensions as removal from the store does not trigger automatic uninstalls.

Google has released the February 2025 Android security updates, patching a total of 48 vulnerabilities. Among these fixes is a critical zero-day kernel vulnerability, identified as CVE-2024-53104, which Google has confirmed is being actively exploited in the wild. This particular flaw is a privilege escalation issue found within the USB Video Class (UVC) driver, potentially allowing attackers to gain elevated permissions on affected devices.
The vulnerability, with a CVSS score of 7.8, stems from an out-of-bounds write condition within the "uvc_parse_format()" function of the "uvc_driver.c" program, specifically when parsing UVC_VS_UNDEFINED frames. This flaw, present since Linux kernel version 2.6.26 released in mid-2008, could lead to memory corruption, program crashes, or even arbitrary code execution. While the specific actors behind the exploitation remain unclear, the potential for "physical" privilege escalation raises concerns about misuse by forensic data extraction tools.

A large-scale malware campaign has compromised over 35,000 websites by injecting malicious JavaScript. The injected scripts redirect users to Chinese-language gambling platforms, specifically under the "Kaiyun" brand. This attack utilizes obfuscated JavaScript payloads to hijack user browsers, replacing legitimate website content with full-page redirects.
This malicious campaign operates by embedding a one-line `` tag into the source code of affected websites. These scripts then reference domains like zuizhongjs[.]com and other similar URLs. Once loaded, these scripts dynamically inject further payloads, manipulating browser behavior and creating a full-screen overlay that redirects users to unlicensed gambling platforms in Mandarin, targeting users in regions where Mandarin is predominantly spoken. The attackers employ techniques such as string concatenation and Unicode escapes to conceal their activities and evade detection by automated security systems.

Google Cloud has launched quantum-safe digital signatures within its Cloud Key Management Service (Cloud KMS), now available in preview. This cybersecurity enhancement prepares users against future quantum threats by aligning with the National Institute of Standards and Technology’s (NIST) post-quantum cryptography (PQC) standards. The upgrade provides developers with the necessary tools to protect encryption.
Google's implementation integrates NIST-standardized algorithms FIPS 204 and FIPS 205, enabling signing and validation processes resilient to attacks from quantum computers. By incorporating these protocols into Cloud KMS, Google enables enterprises to future-proof authentication workflows, which is particularly important for systems requiring long-term security, such as critical infrastructure firmware or software update chains. This allows organizations to manage quantum-safe keys alongside classical ones, facilitating a phased migration.

Google, in collaboration with its Mandiant Threat Intelligence team, has issued a warning about a surge in phishing campaigns targeting higher education institutions in the United States. These campaigns, observed since August 2024, have exploited the academic calendar and institutional trust to deceive students, faculty, and staff. The attacks have been linked to a broader campaign dating back to at least October 2022, targeting thousands of users monthly.
The phishing attacks are strategically timed to coincide with key academic events such as the start of the school year and financial aid deadlines. Attackers have tricked victims into revealing sensitive credentials and financial information by leveraging these high-pressure periods. The campaigns employ various tactics, including hosting malicious Google Forms on compromised university domains and cloning university login portals to carry out payment redirection attacks. Google is addressing security concerns surrounding SMS 2FA codes by replacing Gmail’s SMS authentication with QR codes in the coming months.

Google is introducing a new security feature called Identity Check for Android devices to combat theft. This feature locks sensitive settings, such as device and account passwords, behind biometric authentication when outside a trusted location. This prevents thieves from making unauthorized changes even if they possess the device's passcode. The intent is to safeguard user data and improve overall device security.
Identity Check requires biometric verification for accessing sensitive areas like performing factory resets, changing screen locks, adding new fingerprints, and disabling ‘Find My Device’. It also protects access to developer options and Google Password Manager. Initially, the feature will roll out to Samsung Galaxy devices eligible for One UI 7, both as part of the new OS and potentially on older versions in the near future. Non-Samsung users will receive the security update later in the year.

George Mason University researchers have revealed a novel attack, dubbed "nRootTag," that exploits Apple's Find My network to track computers, smartphones, and IoT devices. This method uses a device’s Bluetooth address to trick the Find My network into identifying the target device as a lost AirTag. This effectively transforms the targeted device into a covert tracking beacon, enabling hackers to monitor its location remotely.
This unauthorized "AirTag" silently transmits Bluetooth signals to nearby Apple devices, which then anonymously relay the device's location via Apple Cloud. According to the research, a stationary computer’s location could be pinpointed to within 10 feet, and a moving e-bike's route could be accurately tracked. The researchers informed Apple about the exploit in July 2024 and recommended that the company update its Find My network to better verify Bluetooth devices.

A new phishing scam is targeting PayPal users by exploiting the platform's address settings. Scammers are sending fraudulent purchase confirmation emails, tricking recipients into contacting them under the guise of resolving unauthorized transactions. These emails often carry the subject line "You added a new address" and include a fake purchase confirmation, such as for a MacBook M4, urging users to call a provided phone number if they didn't authorize the transaction. The goal is to create panic and prompt users to seek help from the scammers.
The scam emails originate from PayPal's legitimate email servers, allowing them to bypass security and spam filters. Scammers exploit PayPal's gift address feature by inserting the phishing message into the Address 2 field of a PayPal account, triggering an official PayPal confirmation email containing the scam message. Once a victim calls the fake PayPal support number, the scammers attempt to gain remote access to the user's device, potentially leading to the theft of personal information or the installation of malware.
