The newly discovered Chinese nation-state actor known as Volt Typhoon has been observed to be active in the wild since at least mid-2020, with the hacking crew linked to never-before-seen tradecraft to retain remote access to targets of interest. The findings come from CrowdStrike, which is tracking the adversary under the name  Vanguard Panda . "The adversary consistently employed ManageEngine Self-service Plus exploits to gain initial access, followed by custom web shells for persistent access, and living-off-the-land (LotL) techniques for lateral movement," the cybersecurity company  said . Volt Typhoon, as known as Bronze Silhouette, is a  cyber espionage group  from China that's been linked to network intrusion operations against the U.S government, defense, and other critical infrastructure organizations. "This adversary has been known to leverage credentials and living-off-the-land techniques to remain hidden and move quickly through targeted environments...

The U.S. Cybersecurity and Infrastructure Security Agency has  added  a batch of six flaws to its Known Exploited Vulnerabilities ( KEV ) catalog, citing evidence of active exploitation. This comprises three vulnerabilities that Apple patched this week ( CVE-2023-32434, CVE-2023-32435, and CVE-2023-32439 ), two flaws in VMware ( CVE-2023-20867  and  CVE-2023-20887 ), and one shortcoming impacting Zyxel devices ( CVE-2023-27992 ). CVE-2023-32434 and CVE-2023-32435, both of which allow code execution, are said to have been exploited as zero-days to deploy spyware as part of a years-long cyber espionage campaign that commenced in 2019. Dubbed Operation Triangulation, the activity culminates in the deployment of  TriangleDB  that's designed to harvest a wide range of information from compromised devices, such as creating, modifying, removing, and stealing files, listing and terminating processes, gathering credentials from iCloud Keychain, and tracking a u...

A U.K. citizen who took part in the massive July 2020 hack of Twitter has been sentenced to five years in prison in the U.S. Joseph James O'Connor (aka PlugwalkJoe), 24, was awarded the sentence on Friday in the Southern District of New York, a little over a month  after  he  pleaded guilty  to the criminal schemes. He was  arrested  in Spain in July 2021. The infamous Twitter breach allowed the defendant and his co-conspirators to obtain unauthorized access to backend tools used by Twitter, abusing them to hijack 130 popular accounts to perpetrate a crypto scam that netted them about $120,000 in illegal profits. "In other instances, the co-conspirators sold access to Twitter accounts to others," the U.S. Department of Justice (DoJ)  said . "O'Connor communicated with others regarding purchasing unauthorized access to a variety of Twitter accounts, including accounts associated with public figures around the world." The defendant has also been acc...

SaaS Adoption is Skyrocketing, Resilience Hasn't Kept Pace SaaS platforms have revolutionized how businesses operate. They simplify collaboration, accelerate deployment, and reduce the overhead of managing infrastructure. But with their rise comes a subtle, dangerous assumption: that the convenience of SaaS extends to resilience. It doesn't. These platforms weren't built with full-scale data protection in mind . Most follow a shared responsibility model — wherein the provider ensures uptime and application security, but the data inside is your responsibility. In a world of hybrid architectures, global teams, and relentless cyber threats, that responsibility is harder than ever to manage. Modern organizations are being stretched across: Hybrid and multi-cloud environments with decentralized data sprawl Complex integration layers between IaaS, SaaS, and legacy systems Expanding regulatory pressure with steeper penalties for noncompliance Escalating ransomware threats and inside...

A threat actor known as  Muddled Libra  is targeting the business process outsourcing (BPO) industry with persistent attacks that leverage advanced social engineering ploys to gain initial access. "The attack style defining Muddled Libra appeared on the cybersecurity radar in late 2022 with the release of the 0ktapus phishing kit, which offered a prebuilt hosting framework and bundled templates," Palo Alto Networks Unit 42  said  in a technical report. Libra is the constellation-themed  designation  given by the cybersecurity company for cybercrime groups. The "muddled" moniker for the threat actor stems from the prevailing ambiguity with regards to the use of the 0ktapus framework. 0ktapus , also known as Scatter Swine, refers to an intrusion set that first came to light in August 2022 in connection with smishing attacks against over 100 organizations, including Twilio and Cloudflare. Then in late 2022, CrowdStrike  detailed  a string of cy...

The case for browser fingerprinting: personalizing user experience, improving fraud detection, and optimizing login security Have you ever heard of browser fingerprinting? You should! It's an online user identification technique that collects information about a visitor's web browser and its configuration preferences to associate individual browsing sessions with a single website visitor.  With browser fingerprinting, many pieces of data can be collected about a user's web browser and device, such as screen resolution, location, language, and operating system. When you stitch these pieces together, they reveal a unique combination of information that forms every user's visitor ID or "digital fingerprint." Websites can use the visitor ID in various ways, including personalizing the user's experience, improving fraud detection, and optimizing login security. This article discusses the case for browser fingerprinting and how to use it safely on your websi...

A new strain of JavaScript dropper has been observed delivering next-stage payloads like Bumblebee and IcedID. Cybersecurity firm Deep Instinct is tracking the malware as  PindOS , which contains the name in its " User-Agent " string. Both  Bumblebee  and IcedID serve as loaders, acting as a vector for other malware on compromised hosts, including ransomware. A recent report from Proofpoint  highlighted  IcedID's abandoning of banking fraud features to solely focus on malware delivery. Bumblebee , notably, is a replacement for another loader called  BazarLoader , which has been attributed to the now-defunct TrickBot and Conti groups. A report from Secureworks in April 2022  found  evidence of collaboration between several actors in the Russian cybercrime ecosystem, including that of  Conti ,  Emotet , and IcedID. Deep Instinct's source code analysis of PindOS shows that it contains comments in Russian, raising the possibility of a...

The U.S. National Security Agency (NSA) on Thursday released guidance to help organizations detect and prevent infections of a Unified Extensible Firmware Interface ( UEFI ) bootkit called  BlackLotus . To that end, the agency is  recommending  that "infrastructure owners take action by hardening user executable policies and monitoring the integrity of the boot partition." BlackLotus is an  advanced  crimeware solution that was first spotlighted in October 2022 by Kaspersky. A UEFI bootkit capable of bypassing Windows Secure Boot protections, samples of the malware have since emerged in the wild. This is accomplished by taking advantage of a known Windows flaw called Baton Drop ( CVE-2022-21894 , CVSS score: 4.4) discovered in vulnerable  boot loaders  not added into the  Secure Boot DBX revocation list . The vulnerability was addressed by Microsoft in January 2022. This loophole could be exploited by threat actors to replace fully patched b...

Internet-facing Linux systems and Internet of Things (IoT) devices are being targeted as part of a new campaign designed to illicitly mine cryptocurrency. "The threat actors behind the attack use a backdoor that deploys a wide array of tools and components such as rootkits and an IRC bot to steal device resources for mining operations," Microsoft threat intelligence researcher Rotem Sde-Or  said . "The backdoor also installs a patched version of OpenSSH on affected devices, allowing threat actors to hijack SSH credentials, move laterally within the network, and conceal malicious SSH connections." To pull off the scheme, misconfigured Linux hosts are brute-forced to gain initial access, following which the threat actors move to disable shell history and fetch a trojanized version of OpenSSH from a remote server. The rogue OpenSSH package is configured to install and launch the backdoor, a shell script that allows the attackers to distribute additional payloads a...

A new phishing campaign codenamed  MULTI#STORM  has set its sights on India and the U.S. by leveraging JavaScript files to deliver remote access trojans on compromised systems. "The attack chain ends with the victim machine infected with multiple unique RAT (remote access trojan) malware instances, such as Warzone RAT and Quasar RAT," Securonix researchers Den Iuzvyk, Tim Peck, and Oleg Kolesnikov  said . "Both are used for command-and-control during different stages of the infection chain." The multi-stage attack chain commences when an email recipient clicks the embedded link pointing to a password-protected ZIP file ("REQUEST.zip") hosted on Microsoft OneDrive with the password "12345." Extracting the archive file reveals a heavily obfuscated JavaScript file ("REQUEST.js") that, when double clicked, activates the infection by executing two PowerShell commands that are responsible for retrieving two separate payloads from OneDri...
