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 North Korea-backed Lazarus Group has been observed deploying a Windows rootkit by taking advantage of an exploit in a Dell firmware driver, highlighting new tactics adopted by the state-sponsored adversary. The Bring Your Own Vulnerable Driver ( BYOVD ) attack, which took place in the autumn of 2021, is another variant of the threat actor's espionage-oriented activity called Operation In(ter)ception  that's directed against aerospace and defense industries. "The campaign started with spear-phishing emails containing malicious Amazon-themed documents and targeted an employee of an aerospace company in the Netherlands, and a political journalist in Belgium," ESET researcher Peter Kálnai  said . Attack chains unfolded upon the opening of the lure documents, leading to the distribution of malicious droppers that were trojanized versions of open source projects, corroborating recent reports from Google's  Mandiant  and  Microsoft . ESET said it uncovered evid

The introduction of Open AI's ChatGPT was a defining moment for the software industry, touching off a GenAI race with its November 2022 release. SaaS vendors are now rushing to upgrade tools with enhanced productivity capabilities that are driven by generative AI. Among a wide range of uses, GenAI tools make it easier for developers to build software, assist sales teams in mundane email writing, help marketers produce unique content at low cost, and enable teams and creatives to brainstorm new ideas.  Recent significant GenAI product launches include Microsoft 365 Copilot, GitHub Copilot, and Salesforce Einstein GPT. Notably, these GenAI tools from leading SaaS providers are paid enhancements, a clear sign that no SaaS provider will want to miss out on cashing in on the GenAI transformation. Google will soon launch its SGE "Search Generative Experience" platform for premium AI-generated summaries rather than a list of websites.  At this pace, it's just a matter of a short time befo

Two years ago Chinese firm Lenovo got banned from supplying equipment for networks of the intelligence and defense services various countries due to hacking and spying concerns. Earlier this year, Lenovo was caught red-handed for selling laptops pre-installed with Superfish malware . One of the most popular Chinese computer manufacturers 'Lenovo' has been caught once again using a hidden Windows feature to preinstall unwanted and unremovable rootkit software on certain Lenovo laptop and desktop systems it sells. The feature is known as " Lenovo Service Engine " (LSE) – a piece of code presents into the firmware on the computer's motherboard.  If Windows is installed, the LSE automatically downloads and installs Lenovo's own software during boot time before the Microsoft operating system is launched, overwriting Windows operating system files. More worrisome part of the feature is that it injects software that updates drivers, firmware, and oth

Cybersecurity researchers have disclosed a new variant of the AvosLocker ransomware that disables antivirus solutions to evade detection after breaching target networks by taking advantage of unpatched security flaws.  "This is the first sample we observed from the U.S. with the capability to disable a defense solution using a legitimate Avast Anti-Rootkit Driver file (asWarPot.sys)," Trend Micro researchers, Christoper Ordonez and Alvin Nieto,  said  in a Monday analysis. "In addition, the ransomware is also capable of scanning multiple endpoints for the Log4j vulnerability (Log4shell) using Nmap  NSE script ." AvosLocker , one of the newer ransomware families to fill the vacuum left by  REvil , has been linked to a number of attacks that targeted critical infrastructure in the U.S., including financial services and government facilities. A ransomware-as-a-service (RaaS) affiliate-based group first spotted in July 2021, AvosLocker goes beyond double extortion

Researchers from Qihoo 360's Netlab security team have released details of a new evolving botnet called " Abcbot " that has been observed in the wild with worm-like propagation features to infect Linux systems and launch distributed denial-of-service (DDoS) attacks against targets. While the earliest version of the botnet dates back to July 2021, new variants observed as recently as October 30 have been equipped with additional updates to strike Linux web servers with weak passwords and are susceptible to N-day vulnerabilities, including a custom implementation of DDoS functionality, indicating that the malware is under continuous development. Netlab's findings also build on a report from Trend Micro early last month, which  publicized  attacks targeting Huawei Cloud with cryptocurrency-mining and cryptojacking malware. The intrusions were also notable for the fact that the malicious shell scripts specifically disabled a process designed to monitor and scan the ser

A previously unknown Linux remote access trojan called Krasue has been observed targeting telecom companies in Thailand by threat actors to main covert access to victim networks at lease since 2021. Named after a  nocturnal female spirit  of Southeast Asian folklore, the malware is "able to conceal its own presence during the initialization phase," Group-IB  said  in a report shared with The Hacker News. The exact initial access vector used to deploy Krasue is currently not known, although it's suspected that it could be via vulnerability exploitation, credential brute-force attacks, or downloaded as part of a bogus software package or binary. The malware's core functionalities are realized through a rootkit that masquerades as an unsigned VMware driver and allows it to maintain persistence on the host without attracting any attention. The rootkit is derived from open-source projects such as Diamorphine, Suterusu, and Rooty. This has raised the possibility that

Since the Shadow Brokers released the zero-day software vulnerabilities and hacking tools – allegedly belonged to the NSA's elite hacking team Equation Group – several hacking groups and individual hackers have started using them in their own way. The April's data dump was believed to be the most damaging release by the Shadow Brokers till the date, as it publicly leaked lots of Windows hacking tools , including dangerous Windows SMB exploit. After the outbreak of WannaCry last week, security researchers have identified multiple different campaigns exploiting Windows SMB vulnerability (CVE-2017-0143), called Eternalblue , which has already compromised hundreds of thousands of computers worldwide. I have been even confirmed by multiple sources in hacking and intelligence community that there are lots of groups and individuals who are actively exploiting Eternalblue for different motives. Moreover, the Eternalblue SMB exploit ( MS17-010 ) has now been ported to  Met

Cyber Security researchers at Guardicore Labs today published a detailed report on a widespread cryptojacking campaign attacking Windows MS-SQL and PHPMyAdmin servers worldwide. Dubbed Nansh0u , the malicious campaign is reportedly being carried out by an APT-style Chinese hacking group who has already infected nearly 50,000 servers and are installing a sophisticated kernel-mode rootkit on compromised systems to prevent the malware from being terminated. The campaign, which dates back to February 26 but was first detected in early-April, has been found delivering 20 different payload versions hosted on various hosting providers. The attack relies on the brute-forcing technique after finding publicly accessible Windows MS-SQL and PHPMyAdmin servers using a simple port scanner. Upon successful login authentication with administrative privileges, attackers execute a sequence of MS-SQL commands on the compromised system to download malicious payload from a remote file server and

Microsoft has announced a new free-to-use initiative aimed at uncovering forensic evidence of sabotage on Linux systems, including rootkits and intrusive malware that may otherwise go undetected. The cloud offering, dubbed Project Freta , is a snapshot-based memory forensic mechanism that aims to provide automated full-system volatile memory inspection of virtual machine (VM) snapshots, with capabilities to spot malicious software, kernel rootkits , and other stealthy malware techniques such as process hiding . The project is named after Warsaw's Freta Street , the birthplace of Marie Curie, the famous French-Polish physicist who brought X-ray medical imaging to the battlefield during World War I. "Modern malware is complex, sophisticated, and designed with non-discoverability as a core tenet," said Mike Walker, Microsoft's senior director of New Security Ventures. "Project Freta intends to automate and democratize VM forensics to a point where every us

Purple Fox , a Windows malware previously known for infecting machines by using exploit kits and phishing emails, has now added a new technique to its arsenal that gives it worm-like propagation capabilities. The ongoing campaign makes use of a "novel spreading technique via indiscriminate port scanning and exploitation of exposed SMB services with weak passwords and hashes," according to  Guardicore researchers , who say the attacks have spiked by about 600% since May 2020. A total of 90,000 incidents have been spotted through the rest of 2020 and the beginning of 2021. First discovered in March 2018, Purple Fox is distributed in the form of malicious ".msi" payloads hosted on nearly 2,000 compromised Windows servers that, in turn, download and execute a component with  rootkit capabilities , which enables the threat actors to hide the malware on the machine and make it easy to evade detection. Guardicore says Purple Fox hasn't changed much post-exploitat

A previously undetected cryptocurrency scam has leveraged a constellation of over 1,000 fraudulent websites to ensnare users into a bogus rewards scheme since at least January 2021. "This massive campaign has likely resulted in thousands of people being scammed worldwide," Trend Micro researchers  said  in a report published last week, linking it to a Russian-speaking threat actor named "Impulse Team." "The scam works via an advanced fee fraud that involves tricking victims into believing that they've won a certain amount of cryptocurrency. However, to get their rewards, the victims would need to pay a small amount to open an account on their website." The compromise chain starts with a direct message propagated via Twitter to lure potential targets into visiting the decoy site. The account responsible for sending the messages has since been closed. The message urges recipients to sign up for an account on the website and apply a promo code specif

Rootkit named as "Necurs" infect 83,427 unique machines during the month of November 2012. It is a multi-purpose rootkits capable of posing a threat to both 32 and 64-bit Windows systems. Distributed via drive-by download on the websites that host the BlackHole exploit kit. Like other rootkits it is able to hide itself from detection and also capable of downloading additional malware from outside. Attackers can maintain remote access to a machine this way in order to monitor activity, send spam or install scareware. Rootkit also stop security applications from functioning and hence no detection. Microsoft list this as  Trojan:Win32/Necurs . Trojan:Win32/Necurs is a family of malware that work together to download additional malware and enable backdoor access and control of your computer. The malware can be installed on its own or alongside rogue security software, such as Rogue:Win32/Winwebsec. The malware downloads itself into the folder " %windi

Cybersecurity researchers have detailed a new campaign that likely targets entities in Southeast Asia with a previously unrecognized Linux malware that's engineered to enable remote access to its operators, in addition to amassing credentials and function as a proxy server. The malware family, dubbed " FontOnLake " by Slovak cybersecurity firm ESET, is said to feature "well-designed modules" that are continuously being upgraded with a broad range of abilities, indicating an active development phase. Samples uploaded to VirusTotal point to the possibility that the very first intrusions utilizing this threat have been happening as early as May 2020. Avast  and  Lacework Labs  are tracking the same malware under the moniker HCRootkit. "The sneaky nature of FontOnLake's tools in combination with advanced design and low prevalence suggest that they are used in targeted attacks," ESET researcher Vladislav Hrčka  said . "To collect data or condu

An unknown threat actor with the capabilities to evolve and tailor its toolset to target environments infiltrated high-profile organizations in Asia and Africa with an evasive Windows rootkit since at least 2018. Called  'Moriya ,' the malware is a "passive backdoor which allows attackers to inspect all incoming traffic to the infected machine, filter out packets that are marked as designated for the malware and respond to them," said Kaspersky researchers Mark Lechtik and Giampaolo Dedola in a Thursday deep-dive. The Russian cybersecurity firm termed the ongoing espionage campaign  'TunnelSnake .' Based on telemetry analysis, less than 10 victims around the world have been targeted to date, with the most prominent targets being two large diplomatic entities in Southeast Asia and Africa. All the other victims were located in South Asia. The first reports of Moriya emerged last November when Kaspersky said it discovered the stealthy implant in the networks

Microsoft on Friday said it's investigating an incident wherein a driver signed by the company turned out to be a malicious Windows rootkit that was observed communicating with command-and-control (C2) servers located in China. The driver, called " Netfilter ," is said to target gaming environments, specifically in the East Asian country, with the Redmond-based firm noting that "the actor's goal is to use the driver to spoof their geo-location to cheat the system and play from anywhere." "The malware enables them to gain an advantage in games and possibly exploit other players by compromising their accounts through common tools like keyloggers," Microsoft Security Response Center (MSRC)  said . It's worth pointing out that Netfilter also refers to a legitimate software package , which enables packet filtering and network address translation for Linux based systems. Microsoft dubbed the malware " Retliften ," alluding to "ne

McAfee DeepSAFE - Anti-rootkit Security Solution McAfee previewed its DeepSAFE hardware-assisted security technology for proactively detecting and preventing stealthy advanced persistent threats (APTs) and malware. The technology, which was co-developed with Intel, sits below the OS, providing the ability to fundamentally change the security game, according to the companies. According to McAfee Labs, more than 1,200 new rootkits per day are detected - equating to 50 per hour every single day. The DeepSAFE technology, which was demonstrated at the Intel Developer Forum in San Francisco, was able to detect and stop a zero-day Agony rootkit from infecting a system in real time. This technology is expected to launch in products later in 2011. Key attributes of McAfee DeepSAFE: Builds the foundation for next-generation hardware-assisted security operating beyond the operating system Provides a trusted view of system events below the operating system Exposes many attacks that are un

The threat actors behind the CopperStealer malware resurfaced with two new campaigns in March and April 2023 that are designed to deliver two novel payloads dubbed CopperStealth and CopperPhish. Trend Micro is tracking the financially motivated group under the name  Water Orthrus . The adversary is also assessed to be  behind   another campaign  known as  Scranos , which was detailed by Bitdefender in 2019. Active since at least 2021, Water Orthrus has a track record of leveraging pay-per-install (PPI) networks to redirect victims landing on  cracked   software download sites  to drop an information stealer codenamed  CopperStealer . Another campaign spotted in August 2022 entailed the use of CopperStealer to distribute  Chromium-based web browser extensions  that are capable of performing unauthorized transactions and transferring cryptocurrency from victims' wallets to ones under attackers' control. The latest attack sequences documented by Trend Micro don't mark mu
