Cybersecurity researchers have discovered a malicious Rust package that's capable of targeting Windows, macOS, and Linux systems, and features malicious functionality to stealthily execute on developer machines by masquerading as an Ethereum Virtual Machine ( EVM ) unit helper tool. The Rust crate, named " evm-units ," was uploaded to crates.io in mid-April 2025 by a user named " ablerust ," attracting more than 7,000 downloads over the past eight months. Another package created by the same author, " uniswap-utils ," listed "evm-units" as a dependency. It was downloaded over 7,400 times. The packages have since been removed from the package repository. "Based on the victim's operating system and whether Qihoo 360 antivirus is running, the package downloads a payload, writes it to the system temp directory, and silently executes it," Socket security researcher Olivia Brown said in a report. "The package appears to retur...

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 threat actor known as Dragon Breath has been observed making use of a multi-stage loader codenamed RONINGLOADER to deliver a modified variant of a remote access trojan called Gh0st RAT. The campaign, which is primarily aimed at Chinese-speaking users, employs trojanized NSIS installers masquerading as legitimate like Google Chrome and Microsoft Teams, according to Elastic Security Labs. "The infection chain employs a multi-stage delivery mechanism that leverages various evasion techniques, with many redundancies aimed at neutralising endpoint security products popular in the Chinese market," security researchers Jia Yu Chan and Salim Bitam said . "These include bringing a legitimately signed driver, deploying custom WDAC policies, and tampering with the Microsoft Defender binary through PPL [Protected Process Light] abuse." Dragon Breath, also known as APT-Q-27 and Golden Eye, was previously highlighted by Sophos in May 2023 in connection with a campaign ...

Hardly two month ago we reported about the first widely spread Android Bootkit malware , dubbed as ' Oldboot.A ', which infected more than 500,000 Smartphone users worldwide with Android operating system in last eight months, especially in China. Oldboot is a piece of Android malware that's designed to re-infect Mobile devices even after a thorough cleanup. It resides in the memory of infected devices;  It modify the devices’ boot partition and booting script file to launch system service and extract malicious application during the early stage of system’s booting. Yet another alarming report about Oldboot malware has been released by the Chinese Security Researchers from ' 360 Mobile Security '. They have discovered a new variant of the Oldboot family, dubbed as ' Oldboot.B ', designed exactly as Oldboot.A, but new variant has advance stealth techniques. Especially, the defense against with antivirus software, malware analyzer, and automatic a...

Cybersecurity researchers have disclosed a malware campaign that uses fake software installers masquerading as popular tools like LetsVPN and QQ Browser to deliver the Winos 4.0 framework. The campaign, first detected by Rapid7 in February 2025, involves the use of a multi-stage, memory-resident loader called Catena. "Catena uses embedded shellcode and configuration switching logic to stage payloads like Winos 4.0 entirely in memory, evading traditional antivirus tools," security researchers Anna Širokova and Ivan Feigl said . "Once installed, it quietly connects to attacker-controlled servers – mostly hosted in Hong Kong – to receive follow-up instructions or additional malware." The attacks, like those that have deployed Winos 4.0 in the past, appear to focus specifically on Chinese-speaking environments, with the cybersecurity company calling out the "careful, long-term planning" by a very capable threat actor. Winos 4.0 (aka ValleyRAT) was first ...

A new rootkit that uses the master boot record (MBR) to hide itself has been discovered in China and is being used to install an online game password stealer. The bootkit is installed on the computer by a trojan downloader distributed from a Chinese adult site and is detected by Kaspersky as Rookit.Win32.Fisp.a. Once executed, the rootkit makes a copy of the old MBR and replaces the sectors with its own code which includes an encrypted driver. When the computer boots, the malicious code executes and restores the original MBR so that Windows can load normally. It then uses hooks to replace the fips.sys system driver with a malicious one. "It should be noted that the driver fips.sys is not required for the operating system to run correctly, so the system won’t crash when it is replaced," says Kaspersky Lab expert Vyacheslav Zakorzhevsky. The driver scans loaded processes to determine if they belong to one of over a dozen antivirus programs and prevent them from running...

The threat actor known as Transparent Tribe has been attributed to a fresh set of attacks targeting Indian governmental, academic, and strategic entities with a remote access trojan (RAT) that grants them persistent control over compromised hosts. "The campaign employs deceptive delivery techniques, including a weaponized Windows shortcut (LNK) file masquerading as a legitimate PDF document and embedded with full PDF content to evade user suspicion," CYFIRMA said in a technical report. Transparent Tribe, also called APT36, is a hacking group that's known for mounting cyber espionage campaigns against Indian organizations. Assessed to be of Pakistani origin, the state-sponsored adversary has been active since at least 2013. The threat actor boasts of an ever-evolving arsenal of RATs to realize its goals. Some of the trojans put to use by Transparent Tribe in recent years include CapraRAT , Crimson RAT , ElizaRAT , and DeskRAT . The latest set of attacks began with ...

We have all heard of the "cybersecurity skills gap" — firms' inability to hire and retain high-level cybersecurity talent. I see this gap manifesting in two ways. First, companies that want to hire cybersecurity talent simply cannot find candidates with sufficient skills. Second, companies that cannot afford specialized cybersecurity talent and therefore lack the necessary skills to adequately protect their organizations from the growing and increasingly sophisticated cyber threats. Both of these are real problems, and both can lead to devastating consequences. It's also fair to say that most cybersecurity teams today are overworked and understaffed. One of the primary reasons we need such high-level cybersecurity skills lies in the shortcomings of cybersecurity technologies. Due to the changing and increasingly sophisticated stream of attack techniques, the breadth and depth of cybersecurity defensive technologies used to combat these threats and protect org...

The remote access trojan known as Gh0st RAT has been observed being delivered by an "evasive dropper" called Gh0stGambit as part of a drive-by download scheme targeting Chinese-speaking Windows users. These infections stem from a fake website ("chrome-web[.]com") serving malicious installer packages masquerading as Google's Chrome browser, indicating that users searching for the software on the web are being singled out. Gh0st RAT is a long-standing malware that has been observed in the wild since 2008, manifesting in the form of different variants over the years in campaigns primarily orchestrated by China-nexus cyberespionage groups. Some iterations of the trojan have also been previously deployed by infiltrating poorly-secured MS SQL server instances, using it as a conduit to install the Hidden open-source rootkit. According to cybersecurity firm eSentire, which discovered the latest activity, the targeting of Chinese-speaking users is based on ...

Serious security vulnerability was recently discovered on the Samsung flagship Galaxy S4 device, claiming that attackers can use it to silently send text messages. Qihoo 360 Technology, an antivirus company based in China, said that this particular vulnerability is related to the " cloud backup " feature of Galaxy S4, which is not properly protected and can be abused. This vulnerability was first discovered on June 17 and already reported the issue to Samsung and the company is already in the process of developing an official update to fix the vulnerability. A rogue mobile application could contain code exploiting the vulnerability to send fraudulent scam text messages ordering premium-rate services, the firm said. By exploiting the vulnerable cloud backup feature, malware could pretend to be the identity of any contact, friend, relative, or organization when faking phishing SMS messages. When these phishing SMS messages are received, users may be tricked i...

A Golang implementation of Cobalt Strike called Geacon is likely to garner the attention of threat actors looking to target Apple macOS systems. That's according to findings from SentinelOne, which observed an increase in the number of Geacon payloads appearing on VirusTotal in recent months. "While some of these are likely red-team operations, others bear the characteristics of genuine malicious attacks," security researchers Phil Stokes and Dinesh Devadoss  said  in a report. Cobalt Strike  is a well-known red teaming and adversary simulation tool developed by Fortra. Owing to its myriad capabilities, illegally cracked versions of the software have been abused by threat actors over the years. While post-exploitation activity associated with Cobalt Strike has primarily singled out Windows, such attacks against macOS are something of a rarity. In May 2022, software supply chain firm Sonatype  disclosed  details of a rogue Python package called " pymafka "...

If you think that only CPU updates that address this year's major security flaws— Meltdown and Spectre —are the only ones you are advised to grab immediately, there are a handful of major security flaws that you should pay attention to. Microsoft has issued its first Patch Tuesday for 2018 to address 56 CVE-listed flaws, including a zero-day vulnerability in MS Office related that had been actively exploited by several threat groups in the wild. Sixteen of the security updates are listed as critical, 38 are rated important, one is rated moderate, and one is rated as low in severity. The updates address security flaws in Windows, Office, Internet Explorer, Edge, ChakraCore, ASP.NET, and the .NET Framework. The zero-day vulnerability ( CVE-2018-0802 ), described by Microsoft as a memory corruption flaw in Office, is already being targeted in the wild by several threat actor groups in the past few months. The vulnerability, discovered by several researchers from Chinese com...

Since most security tools also keep an eye on the network traffic to detect malicious IP addresses, attackers are increasingly adopting infrastructure of legitimate services in their attacks to hide their malicious activities. Cybersecurity researchers have now spotted a new malware attack campaign linked to the notorious DarkHydrus APT group that uses Google Drive as its command-and-control (C2) server. DarkHydrus first came to light in August last year when the APT group was leveraging the open-source Phishery tool to carry out credential-harvesting campaign against government entities and educational institutions in the Middle East. The latest malicious campaign conducted by the DarkHydrus APT group was also observed against targets in the Middle East, according to reports published by the 360 Threat Intelligence Center ( 360TIC ) and Palo Alto Networks. This time the advanced threat attackers are using a new variant of their backdoor Trojan, called RogueRobin , which i...

It seems sophisticated hackers have changed the way they conduct targeted cyber operations—instead of investing in zero-days and developing their malware; some hacking groups have now started using ready-made malware just like script kiddies. Possibly, this could be a smart move for state-sponsored hackers to avoid being attributed easily. Security researchers from multiple security firms, including Arbor Networks and FireEye , independently discovered a series of malware campaigns primarily targeting aerospace, defence contractors and manufacturing sectors in various countries, including the United States, Thailand, South Korea and India. What's common? All these attack campaigns, conducted by various hacking groups, eventually install same information and password stealer malware—dubbed FormBook —on the targeted systems. FormBook is nothing but a " malware-as-as-service ," which is an affordable piece of data-stealing and form-grabbing malware that has been ...

Since all the versions of the popular game ‘ Grand Theft ’ gone blatant and during the first week of the release of the Grand Theft Auto 4 in 2008, it topped half of millions of dollars, sold 3.6 million copies and generated $310 million in sales i.e., earning about 5 times as much as the blockbuster movie - Iron Man. But the latest version -- Grand Theft Auto V is only available for the Xbox 360 and PS3 and there are rumors of a PC version of it on GameStop's PowerUp Rewards website. So, it’s very common that if I offer you Grand Theft Auto V for PC, you eagerly want it.  Mind this, " There is no Grand Theft Auto V for PC ," accept the reality and don’t let cyber criminals take leverage of this fact. If you receive any email that alerts that you have been invited to the PC beta test for the game, considering it unreal, don’t click on embedded links in the email because it can lead you to several bad websites that will infect you with all kinds of malwa...
