New Ducktail Infostealer Malware Targeting Facebook Business and Ad Accounts

New Ducktail Infostealer Malware Targeting Facebook Business and Ad Accounts

July 27, 2022Ravie Lakshmanan
Facebook business and advertising accounts are at the receiving end of an ongoing campaign dubbed  Ducktail  designed to seize control as part of a financially driven cybercriminal operation.  "The threat actor targets individuals and employees that may have access to a Facebook Business account with an information-stealer malware," Finnish cybersecurity company WithSecure (formerly F-Secure Business)  said  in a new report. "The malware is designed to steal browser cookies and take advantage of authenticated Facebook sessions to steal information from the victim's Facebook account and ultimately hijack any Facebook Business account that the victim has sufficient access to." The attacks, attributed to a Vietnamese threat actor, are said to have begun in the latter half of 2021, with primary targets being individuals with managerial, digital marketing, digital media, and human resources roles in companies. The idea is to target employees with high-level acc
Malicious IIS Extensions Gaining Popularity Among Cyber Criminals for Persistent Access

Malicious IIS Extensions Gaining Popularity Among Cyber Criminals for Persistent Access

July 27, 2022Ravie Lakshmanan
Threat actors are increasingly abusing Internet Information Services ( IIS ) extensions to backdoor servers as a means of establishing a "durable persistence mechanism." That's according to a  new warning  from the Microsoft 365 Defender Research Team, which said that "IIS backdoors are also harder to detect since they mostly reside in the same directories as legitimate modules used by target applications, and they follow the same code structure as clean modules." Attack chains taking this approach commence with weaponizing a critical vulnerability in the hosted application for initial access, using this foothold to drop a script web shell as the first stage payload. This web shell then becomes the conduit for installing a rogue IIS module to provide highly covert and persistent access to the server, in addition to monitoring incoming and outgoing requests as well as running remote commands. Indeed, earlier this month, Kaspersky researchers disclosed a cam
Experts Find Similarities Between New LockBit 3.0 and BlackMatter Ransomware

Experts Find Similarities Between New LockBit 3.0 and BlackMatter Ransomware

July 26, 2022Ravie Lakshmanan
Cybersecurity researchers have reiterated similarities between the latest iteration of the LockBit ransomware and  BlackMatter , a rebranded variant of the DarkSide ransomware strain that closed shop in November 2021. The new version of  LockBit , called LockBit 3.0 aka LockBit Black, was released in June 2022, launching a brand new leak site and what's the very first ransomware bug bounty program, alongside Zcash as a cryptocurrency payment option. Its encryption process involves appending the extension "HLJkNskOq" or "19MqZqZ0s" to each and every file and changing the icons of the locked files to that of the .ico file that's dropped by the LockBit sample to kick-start the infection. "The ransomware then drops its ransom note, which references 'Ilon Musk' and the European Union's General Data Protection Regulation (GDPR)," Trend Micro researchers  said  in a Monday report. "Lastly, it changes the wallpaper of the victim's
Hackers Increasingly Using WebAssembly Coded Cryptominers to Evade Detection

Hackers Increasingly Using WebAssembly Coded Cryptominers to Evade Detection

July 26, 2022Ravie Lakshmanan
As many as 207 websites have been infected with malicious code designed to launch a cryptocurrency miner by leveraging WebAssembly (Wasm) on the browser. Web security company Sucuri, which published details of the campaign, said it launched an investigation after one of its clients had their computer slowed down significantly every time upon navigating to their own WordPress portal. This uncovered a compromise of a theme file to inject malicious JavaScript code from a remote server -- hxxps://wm.bmwebm[.]org/auto.js -- that's loaded whenever the website's page is accessed. "Once decoded, the contents of auto.js immediately reveal the functionality of a cryptominer which starts mining when a visitor lands on the compromised site," Sucuri malware researcher Cesar Anjos  said . What's more, the deobfuscated auto.js code makes use of WebAssembly to run low-level binary code directly on the browser. WebAssembly , which is supported by all major browsers, is a  b
SmokeLoader Infecting Targeted Systems with Amadey Info-Stealing Malware

SmokeLoader Infecting Targeted Systems with Amadey Info-Stealing Malware

July 26, 2022Ravie Lakshmanan
An information-stealing malware called Amadey is being distributed by means of another backdoor called SmokeLoader. The attacks hinge on tricking users into downloading SmokeLoader that masquerades as software cracks, paving the way for the deployment of Amadey, researchers from the AhnLab Security Emergency Response Center (ASEC)  said  in a report published last week. Amadey , a botnet that  first appeared  around October 2018 on Russian underground forums for $600, is equipped to siphon crendentials, capture screenshots, system metadata, and even information about antivirus engines and additional malware installed on an infected machine. While a feature improvement spotted last July by Walmart Global Tech  incorporated  functionality for harvesting data from Mikrotik routers and Microsoft Outlook, the toolset has since been upgraded to capture information from FileZilla, Pidgin, Total Commander FTP Client, RealVNC, TightVNC, TigerVNC, and WinSCP. Its main goal, however, is t
Hackers Exploit PrestaShop Zero-Day to Steal Payment Data from Online Stores

Hackers Exploit PrestaShop Zero-Day to Steal Payment Data from Online Stores

July 25, 2022Ravie Lakshmanan
Malicious actors are exploiting a previously unknown security flaw in the open source PrestaShop e-commerce platform to inject malicious skimmer code designed to swipe sensitive information. "Attackers have found a way to use a security vulnerability to carry out arbitrary code execution in servers running PrestaShop websites," the company  noted  in an advisory published on July 22. PrestaShop is  marketed  as the leading open-source e-commerce solution in Europe and Latin America, used by nearly 300,000 online merchants worldwide. The goal of the infections is to introduce malicious code capable of stealing payment information entered by customers on checkout pages. Shops using outdated versions of the software or other vulnerable third-party modules appear to be the prime targets.  The PrestaShop maintainers also said they found a zero-day flaw in its service that they said has been addressed in  version 1.7.8.7 , although they cautioned that "we cannot be sure
Experts Uncover New 'CosmicStrand' UEFI Firmware Rootkit Used by Chinese Hackers

Experts Uncover New 'CosmicStrand' UEFI Firmware Rootkit Used by Chinese Hackers

July 25, 2022Ravie Lakshmanan
An unknown Chinese-speaking threat actor has been attributed to a new kind of sophisticated Unified Extensible Firmware Interface ( UEFI ) firmware rootkit called  CosmicStrand . "The rootkit is located in the firmware images of Gigabyte or ASUS motherboards, and we noticed that all these images are related to designs using the H81 chipset," Kaspersky researchers  said  in a new report published today. "This suggests that a common vulnerability may exist that allowed the attackers to inject their rootkit into the firmware's image." Victims identified are said to be private individuals located in China, Vietnam, Iran, and Russia, with no discernible ties to any organization or industry vertical. Rootkits, which are malware implants that are capable of embedding themselves in the deepest layers of the operating system, have morphed from a rarity to an increasingly common occurrence in the threat landscape, equipping threat actors with stealth and persistence f
Racoon Stealer is Back — How to Protect Your Organization

Racoon Stealer is Back — How to Protect Your Organization

July 25, 2022The Hacker News
The Racoon Stealer malware as a service platform gained notoriety several years ago for its ability to extract data that is stored within a Web browser. This data initially included passwords and cookies, which sometimes allow a recognized device to be authenticated without a password being entered. Racoon Stealer was also designed to steal auto-fill data, which can include a vast trove of personal information ranging from basic contact data to credit card numbers. As if all of that were not enough, Racoon Stealer also had the ability to steal cryptocurrency and to steal (or drop) files on an infected system. As bad as Racoon Stealer might have been, its developers have recently created a new version that is designed to be far more damaging than the version that previously existed.  New Racoon Stealer Capabilities The new version of Raccoon Stealer  still has the ability to steal browser passwords, cookies, and auto-fill data. It also has the ability to steal any credit card numbe
Roaming Mantis Financial Hackers Targeting Android and iPhone Users in France

Roaming Mantis Financial Hackers Targeting Android and iPhone Users in France

July 24, 2022Ravie Lakshmanan
The mobile threat campaign tracked as  Roaming Mantis  has been linked to a new wave of compromises directed against French mobile phone users, months after it expanded its targeting to include European countries. No fewer than 70,000 Android devices are said to have been infected as part of the active malware operation, Sekoia said in a report published last week. Attack chains involving  Roaming Mantis , a financially motivated Chinese threat actor, are known to either deploy a piece of banking trojan named MoqHao (aka XLoader) or redirect iPhone users to credential harvesting landing pages that mimic the iCloud login page. "MoqHao (aka Wroba, XLoader for Android) is an Android remote access trojan (RAT) with information-stealing and backdoor capabilities that likely spreads via SMS," Sekoia researchers  said . It all starts with a phishing SMS, a technique known as smishing, enticing users with package delivery-themed messages containing rogue links, that, when clic
Microsoft Resumes Blocking Office VBA Macros by Default After 'Temporary Pause'

Microsoft Resumes Blocking Office VBA Macros by Default After 'Temporary Pause'

July 22, 2022Ravie Lakshmanan
Microsoft has officially resumed blocking Visual Basic for Applications (VBA) macros by default across Office apps, weeks after temporarily announcing plans to roll back the change. "Based on our review of customer feedback, we've made updates to both our  end user  and our  IT admin  documentation to make clearer what options you have for different scenarios," the company  said  in an update on July 20. Earlier this February, Microsoft publicized its plans to disable macros by default in Office applications such as Access, Excel, PowerPoint, Visio, and Word as a way to prevent threat actors from abusing the feature to deliver malware. It's a known fact that a majority of the damaging cyberattacks today leverage email-based phishing lures to spread bogus documents containing malicious macros as a primary vector for initial access. "Macros can add a lot of functionality to Office, but they are often used by people with bad intentions to distribute malware to
Candiru Spyware Caught Exploiting Google Chrome Zero-Day to Target Journalists

Candiru Spyware Caught Exploiting Google Chrome Zero-Day to Target Journalists

July 21, 2022Ravie Lakshmanan
The actively exploited but now-fixed Google Chrome zero-day flaw that came to light at the start of this month was weaponized by an Israeli spyware company and used in attacks targeting journalists in the Middle East. Czech cybersecurity firm Avast linked the exploitation to  Candiru  (aka Saito Tech), which has a history of  leveraging previously unknown flaws  to deploy a Windows malware dubbed DevilsTongue , a modular implant with  Pegasus -like capabilities. Candiru, along with NSO Group, Computer Security Initiative Consultancy PTE. LTD., and Positive Technologies, were  added to the entity list  by the U.S. Commerce Department in November 2021 for engaging in "malicious cyber activities." "Specifically, a large portion of the attacks took place in Lebanon, where journalists were among the targeted parties," security researcher Jan Vojtěšek, who reported the discovery of the flaw,  said  in a write-up. "We believe the attacks were highly targeted."
New Linux Malware Framework Lets Attackers Install Rootkit on Targeted Systems

New Linux Malware Framework Lets Attackers Install Rootkit on Targeted Systems

July 21, 2022Ravie Lakshmanan
A never-before-seen Linux malware has been dubbed a "Swiss Army Knife" for its modular architecture and its capability to install rootkits. This previously undetected Linux threat, called  Lightning Framework  by Intezer, is equipped with a plethora of features, making it one of the most intricate frameworks developed for targeting Linux systems. "The framework has both passive and active capabilities for communication with the threat actor, including opening up SSH on an infected machine, and a polymorphic malleable command and control configuration," Intezer researcher Ryan Robinson  said  in a new report published today. Central to the malware is a downloader ("kbioset") and a core ("kkdmflush") module, the former of which is engineered to retrieve at least seven different plugins from a remote server that are subsequently invoked by the core component. In addition, the downloader is also responsible for establishing the persistence of t

Hackers Use Evilnum Malware to Target Cryptocurrency and Commodities Platforms

July 21, 2022Ravie Lakshmanan
The advanced persistent threat (APT) actor tracked as Evilnum is once again exhibiting signs of renewed activity aimed at European financial and investment entities. "Evilnum is a backdoor that can be used for data theft or to load additional payloads," enterprise security firm Proofpoint  said  in a report shared with The Hacker News. "The malware includes multiple interesting components to evade detection and modify infection paths based on identified antivirus software." Targets include organizations with operations supporting foreign exchanges, cryptocurrency, and decentralized finance (DeFi). The latest spate of attacks are said to have commenced in late 2021. The findings also dovetail with a report from Zscaler last month that  detailed  low-volume targeted attack campaigns launched against companies in Europe and the U.K. Active since 2018,  Evilnum  is tracked by the wider cybersecurity community using the names TA4563 and DeathStalker, with infection

FBI Seizes $500,000 Ransomware Payments and Crypto from North Korean Hackers

July 21, 2022Ravie Lakshmanan
The U.S. Department of Justice (DoJ) has announced the seizure of $500,000 worth of Bitcoin from North Korean hackers who extorted digital payments from several organizations by using a new ransomware strain known as Maui. "The seized funds include ransoms paid by healthcare providers in Kansas and Colorado," the DoJ  said  in a press release issued Tuesday. The recovery of the bitcoin ransoms comes after the agency said it took control of two cryptocurrency accounts that were used to receive payments to the tune of $100,000 and $120,000 from the medical centers. The DoJ did not disclose where the rest of the payments originated from. "Reporting cyber incidents to law enforcement and cooperating with investigations not only protects the United States, it is also good business," said Assistant Attorney General Matthew G. Olsen of the DoJ's National Security Division. "The reimbursement to these victims of the ransom shows why it pays to work with law en
Google Adds Support for DNS-over-HTTP/3 in Android to Keep DNS Queries Private

Google Adds Support for DNS-over-HTTP/3 in Android to Keep DNS Queries Private

July 20, 2022Ravie Lakshmanan
Google on Tuesday officially announced support for DNS-over-HTTP/3 (DoH3) for Android devices as part of a Google Play system update designed to keep DNS queries private. To that end, Android smartphones running Android 11 and higher are expected to use DoH3 instead of DNS-over-TLS ( DoT ), which was incorporated into the mobile operating system with Android 9.0. DoH3 is also an alternative to DNS-over-HTTPS ( DoH ), a mechanism for carrying out remote Domain Name System (DNS) resolution through an encrypted connection, effectively preventing third parties from snooping on users' browsing activities. HTTP/3 , the first major upgrade to the hypertext transfer protocol since HTTP/2 was introduced in May 2015, is designed to use a new transport layer protocol called  QUIC  that's already supported by major browsers such as Google Chrome, Microsoft Edge, Mozilla Firefox, and Apple Safari. The low-latency protocol, developed by Google in 2012, relies on the User Datagram Prot
New Rust-based Ransomware Family Targets Windows, Linux, and ESXi Systems

New Rust-based Ransomware Family Targets Windows, Linux, and ESXi Systems

July 20, 2022Ravie Lakshmanan
Kaspersky security researchers have disclosed details of a brand-new ransomware family written in Rust, making it the third strain after  BlackCat  and  Hive  to use the programming language. Luna, as it's called, is "fairly simple" and can run on Windows, Linux, and ESXi systems, with the malware banking on a combination of  Curve25519  and  AES  for encryption. "Both the Linux and ESXi samples are compiled using the same source code with some minor changes from the Windows version," the Russian firm  noted  in a report published today. Advertisements for Luna on darknet forums suggest that the ransomware is intended for use only by Russian-speaking affiliates. Its core developers are also believed to be of Russian origin owing to spelling mistakes in the ransom note hard-coded within the binary. "Luna confirms the trend for cross-platform ransomware," the researchers stated, adding how the platform agnostic nature of languages like Golang and R
Russian Hackers Tricked Ukrainians with Fake "DoS Android Apps to Target Russia"

Russian Hackers Tricked Ukrainians with Fake "DoS Android Apps to Target Russia"

July 19, 2022Ravie Lakshmanan
Russian threat actors capitalized on the  ongoing conflict  against Ukraine to distribute Android malware camouflaged as an app for pro-Ukrainian hacktivists to launch distributed denial-of-service (DDoS) attacks against Russian sites. Google Threat Analysis Group (TAG) attributed the malware to Turla, an advanced persistent threat also known as Krypton, Venomous Bear, Waterbug, and Uroburos, and linked to Russia's Federal Security Service (FSB). "This is the first known instance of Turla distributing Android-related malware," TAG researcher Billy Leonard  said . "The apps were not distributed through the Google Play Store, but hosted on a domain controlled by the actor and disseminated via links on third party messaging services." It's worth noting that the  onslaught  of  cyberattacks  in the immediate aftermath of Russia's unprovoked invasion of Ukraine prompted the latter to  form an IT Army  to stage counter-DDoS attacks against Russian website

Russian Hackers Using DropBox and Google Drive to Drop Malicious Payloads

July 19, 2022Ravie Lakshmanan
The Russian state-sponsored hacking collective known as APT29 has been attributed to a new phishing campaign that takes advantage of legitimate cloud services like Google Drive and Dropbox to deliver malicious payloads on compromised systems. "These campaigns are believed to have targeted several Western diplomatic missions between May and June 2022," Palo Alto Networks Unit 42  said  in a Tuesday report. "The lures included in these campaigns suggest targeting of a foreign embassy in Portugal as well as a foreign embassy in Brazil." APT29, also tracked under the monikers Cozy Bear, Cloaked Ursa, or The Dukes, has been characterized as an organized cyberespionage group working to collect intelligence that aligns with Russia's strategic objectives. Some aspects of the advanced persistent threat's activities, including the infamous  SolarWinds supply chain attack  of 2020, are separately tracked by Microsoft under the name Nobelium, with Mandiant calling i
