Cybersecurity researchers have discovered a new Raspberry Robin campaign wave that has been propagating the malware through malicious Windows Script Files ( WSFs ) since March 2024. "Historically, Raspberry Robin was known to spread through removable media like USB drives, but over time its distributors have experimented with other initial infection vectors," HP Wolf Security researcher Patrick Schläpfer  said  in a report shared with The Hacker News. Raspberry Robin, also called QNAP worm, was  first spotted  in September 2021 that has since  evolved into a downloader  for various other payloads in recent years, such as SocGholish, Cobalt Strike, IcedID, BumbleBee, and TrueBot, and also serving as a precursor for ransomware. While the malware was initially distributed by means of USB devices containing LNK files that retrieved the payload from a compromised QNAP device, it has since  adopted other methods  such as social engineering and malvertising. It's attribute

Multiple security vulnerabilities have been disclosed in LG webOS running on its smart televisions that could be exploited to bypass authorization and gain root access on the devices. The findings come from Romanian cybersecurity firm Bitdefender, which discovered and reported the flaws in November 2023. The issues were fixed by LG as part of updates released on March 22, 2024. The vulnerabilities are tracked from CVE-2023-6317 through CVE-2023-6320 and impact the following versions of webOS - webOS 4.9.7 - 5.30.40 running on LG43UM7000PLA webOS 5.5.0 - 04.50.51 running on OLED55CXPUA webOS 6.3.3-442 (kisscurl-kinglake) - 03.36.50 running on OLED48C1PUB webOS 7.3.1-43 (mullet-mebin) - 03.33.85 running on OLED55A23LA A brief description of the shortcomings is as follows - CVE-2023-6317  - A vulnerability that allows an attacker to bypass PIN verification and add a privileged user profile to the TV set without requiring user interaction CVE-2023-6318  - A vulnerability th

The need for vCISO services is growing. SMBs and SMEs are dealing with more third-party risks, tightening regulatory demands and stringent cyber insurance requirements than ever before. However, they often lack the resources and expertise to hire an in-house security executive team. By outsourcing security and compliance leadership to a vCISO, these organizations can more easily obtain cybersecurity expertise specialized for their industry and strengthen their cybersecurity posture. MSPs and MSSPs looking to meet this growing vCISO demand are often faced with the same challenge. The demand for cybersecurity talent far exceeds the supply. This has led to a competitive market where the costs of hiring and retaining skilled professionals can be prohibitive for MSSPs/MSPs as well. The need to maintain expertise of both security and compliance further exacerbates this challenge. Cynomi, the first AI-driven vCISO platform , can help. Cynomi enables you - MSPs, MSSPs and consulting firms

A suspected Vietnamese-origin threat actor has been observed targeting victims in several Asian and Southeast Asian countries with malware designed to harvest valuable data since at least May 2023. Cisco Talos is tracking the cluster under the name  CoralRaider , describing it as financially motivated. Targets of the campaign include India, China, South Korea, Bangladesh, Pakistan, Indonesia, and Vietnam. "This group focuses on stealing victims' credentials, financial data, and social media accounts, including business and advertisement accounts," security researchers Chetan Raghuprasad and Joey Chen  said . "They use RotBot, a customized variant of Quasar RAT, and XClient stealer as payloads." Other commodity malware used by the group comprises a combination of remote access trojans and information stealers such as  AsyncRAT ,  NetSupport RAT , and Rhadamanthys . The targeting of business and advertisement accounts has been of particular focus for attacke

U.S. cybersecurity and intelligence agencies have warned of  Phobos ransomware  attacks targeting government and critical infrastructure entities, outlining the various tactics and techniques the threat actors have adopted to deploy the file-encrypting malware. "Structured as a ransomware-as-a-service (RaaS) model, Phobos ransomware actors have targeted entities including municipal and county governments, emergency services, education, public healthcare, and critical infrastructure to successfully ransom several million in U.S. dollars," the government  said . The advisory comes from the U.S. Cybersecurity and Infrastructure Security Agency (CISA), the Federal Bureau of Investigation (FBI), and the Multi-State Information Sharing and Analysis Center (MS-ISAC). Active since May 2019, multiple variants of Phobos ransomware have been identified to date, namely Eking, Eight, Elbie, Devos, Faust, and Backmydata. Late last year, Cisco Talos  revealed  that the threat actors behind the 8B

Details have emerged about a now-patched high-severity security flaw in Apple's Shortcuts app that could permit a shortcut to access sensitive information on the device without users' consent. The vulnerability, tracked as  CVE-2024-23204  (CVSS score: 7.5), was addressed by Apple on January 22, 2024, with the release of  iOS 17.3, iPadOS 17.3 ,  macOS Sonoma 14.3 , and  watchOS 10.3 . "A shortcut may be able to use sensitive data with certain actions without prompting the user," the iPhone maker said in an advisory, stating it was fixed with "additional permissions checks." Apple Shortcuts is a  scripting application  that allows users to create personalized workflows (aka macros) for  executing   specific tasks  on their devices. It comes installed by default on iOS, iPadOS, macOS, and watchOS operating systems. Bitdefender security researcher Jubaer Alnazi Jabin, who discovered and reported the Shortcuts bug, said it could be weaponized to create a

Multiple companies operating in the cryptocurrency sector are the target of an ongoing malware campaign that involves a newly discovered Apple macOS backdoor codenamed RustDoor. RustDoor was  first documented  by Bitdefender last week, describing it as a Rust-based malware capable of harvesting and uploading files, as well as gathering information about the infected machines. It's distributed by masquerading itself as a Visual Studio update. While prior evidence uncovered at least three different variants of the backdoor, the exact initial propagation mechanism remained unknown. That said, the Romanian cybersecurity firm subsequently told The Hacker News that the malware was used as part of a targeted attack rather than a shotgun distribution campaign, noting that it found additional artifacts that are responsible for downloading and executing RustDoor. "Some of these first stage downloaders claim to be PDF files with job offerings, but in reality, are scripts that downl

Apple macOS users are the target of a new Rust-based backdoor that has been operating under the radar since November 2023. The backdoor,  codenamed   RustDoor  by Bitdefender, has been found to impersonate an update for Microsoft Visual Studio and target both Intel and Arm architectures. The exact initial access pathway used to propagate the implant is currently not known, although it's said to be distributed as FAT binaries that contain Mach-O files. Multiple variants of the malware with minor modifications have been detected to date, likely indicating active development. The earliest sample of RustDoor dates back to November 2, 2023. It comes with a wide range of commands that allow it to gather and upload files, and harvest information about the compromised endpoint. Some versions also include configurations with details about what data to collect, the list of targeted extensions and directories, and the directories to exclude. The captured information is then exfiltrate

Multiple security vulnerabilities have been disclosed in Bosch BCC100 thermostats and Rexroth NXA015S-36V-B smart nutrunners that, if successfully exploited, could allow attackers to execute arbitrary code on affected systems. Romanian cybersecurity firm Bitdefender, which  discovered  the flaw in Bosch BCC100 thermostats last August, said the issue could be weaponized by an attacker to alter the device firmware and implant a rogue version. Tracked as  CVE-2023-49722  (CVSS score: 8.3), the high-severity vulnerability was addressed by Bosch in November 2023. "A network port 8899 is always open in BCC101/BCC102/BCC50 thermostat products, which allows an unauthenticated connection from a local WiFi network," the company  said  in an advisory. The issue, at its core, impacts the WiFi microcontroller that acts as a network gateway for the thermostat's logic microcontroller. By exploiting the flaw, an attacker could send commands to the thermostat, including writing a malicious updat

Compromised Facebook business accounts are being used to run bogus ads that employ "revealing photos of young women" as lures to trick victims into downloading an updated version of a malware called  NodeStealer . "Clicking on ads immediately downloads an archive containing a malicious .exe 'Photo Album' file which also drops a second executable written in .NET – this payload is in charge of stealing browser cookies and passwords," Bitdefender  said  in a report published this week. NodeStealer was  first disclosed  by Meta in May 2023 as a JavaScript malware designed to facilitate the takeover of Facebook accounts. Since then, the threat actors behind the operation have leveraged a Python-based variant in their attacks. The malware is part of a  burgeoning cybercrime ecosystem  in Vietnam, where multiple threat actors are leveraging overlapping methods that primarily involve advertising-as-a-vector on Facebook for propagation. The latest campaign disc

Cybersecurity researchers have uncovered a set of malicious artifacts that they say is part of a sophisticated toolkit targeting Apple macOS systems. "As of now, these samples are still largely undetected and very little information is available about any of them," Bitdefender researchers Andrei Lapusneanu and Bogdan Botezatu  said  in a preliminary report published on Friday. The Romanian firm's analysis is based on an examination of four samples that were uploaded to VirusTotal by an unnamed victim. The earliest sample dates back to April 18, 2023. Two of the three malicious programs are said to be generic Python-based backdoors that are designed to target Windows, Linux, and macOS systems. The payloads have been collectively dubbed  JokerSpy . The first constituent is shared.dat, which, once launched, runs an operating system check (0 for Windows, 1 for macOS, and 2 for Linux) and establishes contact with a remote server to fetch additional instructions for execut

The threat actors behind the nascent  Buhti  ransomware have eschewed their custom payload in favor of leaked LockBit and Babuk ransomware families to strike Windows and Linux systems. "While the group doesn't develop its own ransomware, it does utilize what appears to be one custom-developed tool, an information stealer designed to search for and archive specified file types," Symantec  said  in a report shared with The Hacker News. The cybersecurity firm is tracking the cybercrime group under the name  Blacktail . Buhti was first highlighted by Palo Alto Networks Unit 42 in February 2023,  describing  it as a Golang ransomware targeting the Linux platform. Later that same month, Bitdefender revealed the use of a Windows variant that was deployed against Zoho ManageEngine products that were vulnerable to critical remote code execution flaws ( CVE-2022-47966 ). The operators have since been observed swiftly exploiting other severe bugs impacting IBM's Aspera Fasp

Government organizations in Central Asia are the target of a sophisticated espionage campaign that leverages a previously undocumented strain of malware dubbed  DownEx . Bitdefender, in a  report  shared with The Hacker News, said the activity remains active, with evidence likely pointing to the involvement of Russia-based threat actors. The Romanian cybersecurity firm said it first detected the malware in a highly targeted attack aimed at foreign government institutions in Kazakhstan in late 2022. Subsequently, another attack was observed in Afghanistan. The use of a diplomat-themed lure document and the campaign's focus on data exfiltration suggests the involvement of a state-sponsored group, although the exact identity of the hacking outfit remains indeterminate at this stage. The initial intrusion vector for the campaign is suspected to be a spear-phishing email bearing a booby-trapped payload, which is a loader executable that masquerades as a Microsoft Word file. Openi

Researchers from the Bitdefender Mobile Threats team said they have intercepted more than 100,000 malicious SMS messages attempting to distribute  Flubot  malware since the beginning of December. "Findings indicate attackers are modifying their subject lines and using older yet proven scams to entice users to click," the Romanian cybersecurity firm  detailed  in a report published Wednesday. "Additionally, attackers are rapidly changing the countries they are targeting in this campaign." The new wave of attacks is said to have been most active in Australia, Germany, Poland, Spain, Austria, and Italy, among others, with attacks spreading to newer countries like Romania, the Netherlands, and Thailand starting mid-January. FluBot (aka Cabassous) campaigns use smishing as the primary delivery method to target potential victims, wherein users receive an SMS message with the question "Is this you in this video?" and are tricked into clicking a link that inst

Security researchers have uncovered a new, powerful Android malware framework that is being used by cybercriminals to turn legitimate apps into spyware with extensive surveillance capabilities—as part of what seems to be a targeted espionage campaign. Legitimate Android applications when bundled with the malware framework, dubbed Triout, gain capabilities to spy on infected devices by recording phone calls, and monitoring text messages, secretly stealing photos and videos, and collecting location data—all without users' knowledge. The strain of Triout-based spyware apps was first spotted by the security researchers at Bitdefender on May 15 when a sample of the malware was uploaded to VirusTotal by somebody located in Russia, but most of the scans came from Israel. In a white paper (PDF) published Monday, Bitdefender researcher Cristofor Ochinca said the malware sample analyzed by them was packaged inside a malicious version of an Android app which was available on Google Pla

How many Internet-connected devices do you have in your home? I am surrounded by around 25 such devices. It's not just your PC, smartphone, and tablet that are connected to the Internet. Today our homes are filled with tiny computers embedded in everything from security cameras, TVs and refrigerators to thermostat and door locks. However, when it comes to security, people generally ignore to protect all these connected devices and focus on securing their PCs and smartphones with a good antivirus software or a firewall application. What if any of these connected devices, that are poorly configured or insecure by design, get hacked? It would give hackers unauthorized access to your whole network allowing them to compromise other devices connected to the same network, spy on your activities and steal sensitive information by using various sophisticated hacks. There have already been numerous cases of attackers hacking home appliances, industrial control, automotive, medic

Forget about Financial services and Online shopping websites, but at least we expect from Security Firms and Antivirus vendors to keep our personal and Sensitive data Encrypted and Secured. One of the most popular and much-respected Antivirus and computer security firms 'BitDefender' has recently been hacked and has had a portion of its customer data leaked. The Data Breach in BitDefender is incredibly embarrassing for the security firm, not because the company failed to prevent its customers data from hackers, but because the Security company failed to encrypt its customers' most sensitive data . Now, this is something really not expected from a reputed Security Firm. It appears that the hacker, who uses the online alias DetoxRansome , was able to break into a Bitdefender server that hosted the cloud-based management dashboards for its small and medium-sized business clients, and pilfer usernames and passwords belonged to them. They Forget to Encrypt C
