A new wave of phishing campaigns has been observed spreading a previously documented malware called SVCReady . "The malware is notable for the unusual way it is delivered to target PCs — using shellcode hidden in the properties of Microsoft Office documents," Patrick Schläpfer, a threat analyst at HP,  said  in a technical write-up. SVCReady is said to be in its early stage of development, with the authors iteratively updating the malware several times last month. First signs of activity date back to April 22, 2022. Infection chains involve sending Microsoft Word document attachments to targets via email that contain VBA macros to activate the deployment of malicious payloads. But where this campaign stands apart is that instead of employing PowerShell or MSHTA to retrieve next-stage executables from a remote server, the macro runs shellcode stored in the  document properties , which subsequently drops the SVCReady malware. In addition to achieving persistence on the i

The Parrot traffic direction system (TDS) that came to light earlier this year has had a larger impact than previously thought, according to new research. Sucuri, which has been tracking the same campaign since February 2019 under the name "NDSW/NDSX," said that "the malware was one of the top infections" detected in 2021, accounting for more than 61,000 websites. Parrot TDS was  documented  in April 2022 by Czech cybersecurity company Avast, noting that the PHP script had ensnared web servers hosting more than 16,500 websites to act as a gateway for further attack campaigns. This involves appending a piece of malicious code to all JavaScript files on compromised web servers hosting content management systems (CMS) such as WordPress that are in turn said to be breached by taking advantage of weak login credentials and vulnerable plugins. Besides using different obfuscation tactics to conceal the code, the "injected JavaScript may also be found well indent

It comes as no surprise that today's cyber threats are orders of magnitude more complex than those of the past. And the ever-evolving tactics that attackers use demand the adoption of better, more holistic and consolidated ways to meet this non-stop challenge. Security teams constantly look for ways to reduce risk while improving security posture, but many approaches offer piecemeal solutions – zeroing in on one particular element of the evolving threat landscape challenge – missing the forest for the trees.  In the last few years, Exposure Management has become known as a comprehensive way of reigning in the chaos, giving organizations a true fighting chance to reduce risk and improve posture. In this article I'll cover what Exposure Management is, how it stacks up against some alternative approaches and why building an Exposure Management program should be on  your 2024 to-do list. What is Exposure Management?  Exposure Management is the systematic identification, evaluation,

An analysis of  leaked chats  from the notorious  Conti ransomware group  earlier this year has revealed that the syndicate has been working on a set of firmware attack techniques that could offer a path to accessing privileged code on compromised devices. "Control over firmware gives attackers virtually unmatched powers both to directly cause damage and to enable other long-term strategic goals," firmware and hardware security firm Eclypsium  said  in a report shared with The Hacker News. "Such level of access would allow an adversary to cause irreparable damage to a system or to establish ongoing persistence that is virtually invisible to the operating system." Specifically, this includes attacks aimed at embedded microcontrollers such as the Intel  Management Engine  ( ME ), a privileged component that's part of the company's processor chipsets and which can completely bypass the operating system. It's worth noting that the reason for this evolv

As ransomware infections have evolved from purely encrypting data to schemes such as double and triple extortion, a new attack vector is likely to set the stage for future campaigns. Called Ransomware for IoT or  R4IoT  by Forescout, it's a "novel, proof-of-concept ransomware that exploits an IoT device to gain access and move laterally in an IT [information technology] network and impact the OT [operational technology] network." This potential pivot is based on the rapid growth in the number of IoT devices as well as the convergence of IT and OT networks in organizations. The ultimate goal of R4IoT is to leverage exposed and vulnerable IoT devices such as IP cameras to gain an initial foothold, followed by deploying ransomware in the IT network and taking advantage of poor operational security practices to hold mission-critical processes hostage. "By compromising IoT, IT, and OT assets, R4IoT goes beyond the usual encryption and data exfiltration to cause phys

An enhanced version of the XLoader malware has been spotted adopting a probability-based approach to camouflage its command-and-control (C&C) infrastructure, according to the latest research. "Now it is significantly harder to separate the wheat from the chaff and discover the real C&C servers among thousands of legitimate domains used by Xloader as a smokescreen," Israeli cybersecurity company Check Point  said . First spotted in the wild in October 2020, XLoader is a successor to Formbook and a  cross-platform information stealer  that's capable of plundering credentials from web browsers, capturing keystrokes and screenshots, and executing arbitrary commands and payloads. More recently, the  ongoing geopolitical conflict  between Russia and Ukraine has proved to be a lucrative fodder for  distributing XLoader  by means of  phishing emails  aimed at high-ranking government officials in Ukraine. The latest findings from Check Point build on a previous repor

An analysis of the mobile threat landscape in 2022 shows that Spain and Turkey are the most targeted countries for malware campaigns, even as a mix of new and existing banking trojans are increasingly targeting Android devices to conduct on-device fraud (ODF). Other frequently targeted countries include Poland, Australia, the U.S., Germany, the U.K., Italy, France, and Portugal. "The most worrying leitmotif is the increasing attention to On-Device Fraud (ODF)," Dutch cybersecurity company ThreatFabric  said  in a report shared with The Hacker News. "Just in the first five months of 2022 there has been an increase of more than 40% in malware families that abuse Android OS to perform fraud using the device itself, making it almost impossible to detect them using traditional fraud scoring engines." Hydra ,  FluBot  (aka Cabassous),  Cerberus ,  Octo , and  ERMAC  accounted for the most active banking trojans based on the number of samples observed during the same

A nascent Linux-based botnet named Enemybot has expanded its capabilities to include recently disclosed security vulnerabilities in its arsenal to target web servers, Android devices, and content management systems (CMS). "The malware is rapidly adopting one-day vulnerabilities as part of its exploitation capabilities," AT&T Alien Labs  said  in a technical write-up published last week. "Services such as VMware Workspace ONE, Adobe ColdFusion, WordPress, PHP Scriptcase and more are being targeted as well as IoT and Android devices." First disclosed by  Securonix  in March and later by  Fortinet , Enemybot has been linked to a threat actor tracked as Keksec (aka Kek Security, Necro, and FreakOut), with early attacks targeting routers from Seowon Intech, D-Link, and iRZ. Enemybot, which is capable of carrying out  DDoS attacks , draws its origins from several other botnets like Mirai, Qbot, Zbot, Gafgyt, and LolFMe. An analysis of the latest variant reveals

Today's modern companies are built on data, which now resides across countless cloud apps. Therefore  preventing data loss  is essential to your success. This is especially critical for mitigating against rising ransomware attacks — a threat that  57% of security leaders expect to be compromised by within the next year .  As  organizations continue to evolve, in turn so does ransomware . To help you stay ahead, Lookout Chief Strategy Officer, Aaron Cockerill met with Microsoft Chief Security Advisor, Sarah Armstrong-Smith to discuss how  remote work  and the cloud have made it more difficult to spot a ransomware attack, as well as how deploying behavioral-anomaly-based detection can help mitigate ransomware risk.  Access the full interview .  Aaron Cockerill:  I feel like the way modern enterprises operate, which includes a combination of technologies, has allowed the ransomware to thrive. Having experienced this type of attack in my past roles, I know how many CISOs are feeling

A malvertising threat is witnessing a new surge in activity since its emergence earlier this year. Dubbed ChromeLoader , the malware is a "pervasive and persistent browser hijacker that modifies its victims' browser settings and redirects user traffic to advertisement websites," Aedan Russell of Red Canary  said  in a new report. ChromeLoader is a rogue Chrome browser extension and is typically distributed in the form of ISO files via pay-per-install sites and baited social media posts that advertise QR codes to cracked video games and pirated movies. While it primarily functions by hijacking user search queries to Google, Yahoo, and Bing and redirecting traffic to an advertising site, it's also notable for its use of PowerShell to inject itself into the browser and get the extension added. The malware, also known as Choziosi Loader, was first documented by G DATA earlier this February. "For now the only purpose is getting revenue via unsolicited adverti

An unknown advanced persistent threat (APT) group has been linked to a series of spear-phishing attacks targeting Russian government entities since the onset of the Russo-Ukrainian war in late February 2022. "The campaigns [...] are designed to implant a Remote Access Trojan (RAT) that can be used to surveil the computers it infects, and run commands on them remotely," Malwarebytes  said  in a technical report published Tuesday. The cybersecurity company attributed the attacks with low confidence to a Chinese hacking group, citing infrastructure overlaps between the RAT and Sakula Rat malware used by a threat actor known as  Deep Panda . The attack chains, while leveraging different lures over the course of two months, all employed the same malware barring small differences in the source code. The campaign is said to have commenced around February 26, days after Russia's military invasion of Ukraine, with the emails distributing the RAT under the guise of an interac

Cybersecurity researchers have disclosed details of the latest version of the Chaos ransomware line, dubbed Yashma. "Though Chaos ransomware builder has only been in the wild for a year, Yashma claims to be the sixth version (v6.0) of this malware," BlackBerry research and intelligence team said in a report shared with The Hacker News. Chaos is a customizable ransomware builder that  emerged  in underground forums on June 9, 2021, by falsely marketing itself as the .NET version of Ryuk despite sharing no such overlaps with the notorious counterpart. The fact that it's offered for sale also means that any malicious actor can purchase the builder and develop their own ransomware strains, turning it into a potent threat. It has since undergone five successive iterations aimed at improving its functionalities: version 2.0 on June 17, version 3.0 on July 5, version 4.0 on August 5, and version 5.0 in early 2022. While the first three variants of Chaos functioned more l

Even as the operators of Conti threatened to overthrow the Costa Rican government , the notorious cybercrime gang officially took down its attack infrastructure in favor of migrating their malicious cyber activities to other ancillary operations, including Karakurt and BlackByte. "From the negotiations site, chatrooms, messengers to servers and proxy hosts - the Conti brand, not the organization itself, is shutting down," AdvIntel researchers Yelisey Bogusalvskiy and Vitali Kremez  said  in a report. "However, this does not mean that the threat actors themselves are retiring." The voluntary termination, with the exception of its name-and-shame blog, is said to have occurred on May 19, 2022, while an organizational rejig was happening simultaneously to ensure a smooth transition of the ransomware group's members. AdvIntel said Conti, which is also tracked under the moniker  Gold Ulrick , orchestrated its own demise by utilizing information warfare techniques.

Fronton, a distributed denial-of-service (DDoS) botnet that came to light in March 2020, is much more powerful than previously thought, per the latest research. "Fronton is a system developed for coordinated inauthentic behavior on a massive scale," threat intelligence firm Nisos said in a  report  published last week. "This system includes a web-based dashboard known as SANA that enables a user to formulate and deploy trending social media events en masse. The system creates these events that it refers to as Инфоповоды, 'newsbreaks,' utilizing the botnet as a geographically distributed transport." The existence of Fronton, an IoT botnet, became public knowledge following revelations from  BBC Russia  and  ZDNet  in March 2020 after a Russian hacker group known as Digital Revolution published documents that it claimed were obtained after breaking into a subcontractor to the FSB, the Federal Security Service of the Russian Federation. Further investigat

A Linux botnet malware known as XorDdos has witnessed a 254% surge in activity over the last six months, according to latest research from Microsoft. The trojan, so named for carrying out denial-of-service attacks on Linux systems and its use of XOR-based encryption for communications with its command-and-control (C2) server, is  known  to have been  active  since at least 2014. "XorDdos' modular nature provides attackers with a versatile trojan capable of infecting a variety of Linux system architectures," Ratnesh Pandey, Yevgeny Kulakov, and Jonathan Bar Or of the Microsoft 365 Defender Research Team  said  in an exhaustive deep-dive of the malware. "Its SSH brute-force attacks are a relatively simple yet effective technique for gaining root access over a number of potential targets." Remote control over vulnerable IoT and other internet-connected devices is gained by means of secure shell (SSH) brute-force attacks, enabling the malware to form a botnet

Google's Threat Analysis Group (TAG) on Thursday pointed fingers at a North Macedonian spyware developer named Cytrox for developing exploits against five zero-day (aka 0-day) flaws, four in Chrome and one in Android, to target Android users. "The 0-day exploits were used alongside n-day exploits as the developers took advantage of the time difference between when some critical bugs were patched but not flagged as security issues and when these patches were fully deployed across the Android ecosystem," TAG researchers Clement Lecigne and Christian Resell  said . Cytrox is alleged to have packaged the exploits and sold them to different government-backed actors located in Egypt, Armenia, Greece, Madagascar, Côte d'Ivoire, Serbia, Spain, and Indonesia, who, in turn, weaponized the bugs in at least three different campaigns. The commercial surveillance company is the maker of  Predator , an implant  analogous  to that of NSO Group's  Pegasus , and is known to hav

The North Korea-backed Lazarus Group has been observed leveraging the  Log4Shell vulnerability  in VMware Horizon servers to deploy the NukeSped (aka Manuscrypt) implant against targets located in its southern counterpart. "The attacker used the Log4j vulnerability on VMware Horizon products that were not applied with the security patch," AhnLab Security Emergency Response Center (ASEC)  said  in a new report. The intrusions are said to have been first discovered in April, although  multiple threat actors , including those aligned with  China  and  Iran , have employed the same approach to further their objectives over the past few months. NukeSped is a backdoor that can perform various malicious activities based on commands received from a remote attacker-controlled domain. Last year, Kaspersky disclosed a spear-phishing campaign aimed at stealing critical data from defense companies using a NukeSped variant called  ThreatNeedle . Some of the key functions of the bac

Fraudulent domains masquerading as Microsoft's Windows 11 download portal are attempting to trick users into deploying trojanized installation files to infect systems with the Vidar information stealer malware. "The spoofed sites were created to distribute malicious ISO files which lead to a Vidar info-stealer infection on the endpoint," Zscaler  said  in a report. "These variants of Vidar malware fetch the C2 configuration from attacker-controlled social media channels hosted on Telegram and Mastodon network." Some of the rogue distribution vector domains, which were registered last month on April 20, consist of ms-win11[.]com, win11-serv[.]com, and win11install[.]com, and ms-teams-app[.]net. In addition, the cybersecurity firm cautioned that the threat actor behind the impersonation campaign is also leveraging backdoored versions of Adobe Photoshop and other legitimate software such as Microsoft Teams to deliver Vidar malware. The ISO file, for its part,
