Brazilian Hacker Charged for Extorting $3.2M in Bitcoin After Breaching 300,000 Accounts

Brazilian Hacker Charged for Extorting $3.2M in Bitcoin After Breaching 300,000 Accounts

Dec 26, 2024 Cybercrime / Ransomware
A Brazilian citizen has been charged in the United States for allegedly threatening to release data stolen by hacking into a company's network in March 2020. Junior Barros De Oliveira , 29, of Curitiba, Brazil has been charged with four counts of extortionate threats involving information obtained from protected computers and four counts of threatening communications, the U.S. Department of Justice (DoJ) said in an unsealed indictment earlier this week. The said victim, a Brazilian subsidiary of a New Jersey-based company, had its computers breached by the defendant, who then exploited the access to steal confidential customer information from about 300,000 customers on at least three occasions. De Oliveira is alleged to have subsequently sent the chief executive officer (CEO) of the company an email message in September 2020 using an alias, demanding a payment of 300 bitcoin (valued at about $3.2 million at the time) in return for not selling the data. A month later, the de...

Ruijie Networks' Cloud Platform Flaws Could've Exposed 50,000 Devices to Remote Attacks

Dec 25, 2024 Cloud Security / Vulnerability
Cybersecurity researchers have discovered several security flaws in the cloud management platform developed by Ruijie Networks that could permit an attacker to take control of the network appliances. "These vulnerabilities affect both the Reyee platform, as well as Reyee OS network devices," Claroty researchers Noam Moshe and Tomer Goldschmidt said in a recent analysis. "The vulnerabilities, if exploited, could allow a malicious attacker to execute code on any cloud-enabled device, giving them the ability to control tens of thousands of devices." The operational technology (OT) security company, which carried out an in-depth research of the Internet of Things (IoT) vendor, said it not only identified 10 flaws but also devised an attack called "Open Sesame" that can be used to hack into an access point in close physical proximity over the cloud and gain unauthorized access to its network. Of the 10 vulnerabilities , three of them are rated Critical in...

The Hidden Risks of SaaS: Why Built-In Protections Aren't Enough for Modern Data Resilience

The Hidden Risks of SaaS: Why Built-In Protections Aren't Enough for Modern Data Resilience

Jun 26, 2025Data Protection / Compliance
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...
Iran's Charming Kitten Deploys BellaCPP: A New C++ Variant of BellaCiao Malware

Iran's Charming Kitten Deploys BellaCPP: A New C++ Variant of BellaCiao Malware

Dec 25, 2024 Cyber Attack / Malware
The Iranian nation-state hacking group known as Charming Kitten has been observed deploying a C++ variant of a known malware called BellaCiao. Russian cybersecurity company Kaspersky, which dubbed the new version BellaCPP , said it discovered the artifact as part of a "recent" investigation into a compromised machine in Asia that was also infected with the BellaCiao malware. BellaCiao was first documented by Romanian cybersecurity firm Bitdefender in April 2023, describing it as a custom dropper capable of delivering additional payloads. The malware has been deployed by the hacking group in cyber attacks targeting the United States, the Middle East, and India. It's also one of the many bespoke malware families the Charming Kitten actor has developed over the years. Affiliated with Iran's Islamic Revolutionary Guard Corps (IRGC), the advanced persistent threat (APT) group is also known by the monikers APT35, CALANQUE, CharmingCypress, Educated Manticore, ITG18,Mi...
Researchers Uncover PyPI Packages Stealing Keystrokes and Hijacking Social Accounts

Researchers Uncover PyPI Packages Stealing Keystrokes and Hijacking Social Accounts

Dec 24, 2024 Malware / Data Exfiltration
Cybersecurity researchers have flagged two malicious packages that were uploaded to the Python Package Index (PyPI) repository and came fitted with capabilities to exfiltrate sensitive information from compromised hosts, according to new findings from Fortinet FortiGuard Labs. The packages, named zebo and cometlogger , attracted 118 and 164 downloads each, prior to them being taken down. According to ClickPy statistics, a majority of these downloads came from the United States, China, Russia, and India.  Zebo is a "typical example of malware, with functions designed for surveillance, data exfiltration, and unauthorized control," security researcher Jenna Wang said, adding cometlogger "also shows signs of malicious behavior, including dynamic file manipulation, webhook injection, stealing information, and anti-[virtual machine] checks." The first of the two packages, zebo, uses obfuscation techniques, such as hex-encoded strings, to conceal the URL of the co...
North Korean Hackers Pull Off $308M Bitcoin Heist from Crypto Firm DMM Bitcoin

North Korean Hackers Pull Off $308M Bitcoin Heist from Crypto Firm DMM Bitcoin

Dec 24, 2024 Cybercrime / Malware
Japanese and U.S. authorities have formerly attributed the theft of cryptocurrency worth $308 million from cryptocurrency company DMM Bitcoin in May 2024 to North Korean cyber actors. "The theft is affiliated with TraderTraitor threat activity, which is also tracked as Jade Sleet, UNC4899, and Slow Pisces," the agencies said . "TraderTraitor activity is often characterized by targeted social engineering directed at multiple employees of the same company simultaneously." The alert comes courtesy of the U.S. Federal Bureau of Investigation (FBI), the Department of Defense Cyber Crime Center, and the National Police Agency of Japan. It's worth noting that DMM Bitcoin shut down its operations earlier this month in the aftermath of the hack. TraderTraitor refers to a North Korea-linked persistent threat activity cluster that has a history of targeting companies in the Web3 sector, luring victims into downloading malware-laced cryptocurrency apps and ultimately ...
CISA Adds Acclaim USAHERDS Vulnerability to KEV Catalog Amid Active Exploitation

CISA Adds Acclaim USAHERDS Vulnerability to KEV Catalog Amid Active Exploitation

Dec 24, 2024 Vulnerability / Software Security
The U.S. Cybersecurity and Infrastructure Security Agency (CISA) on Monday added a now-patched high-severity security flaw impacting Acclaim Systems USAHERDS to the Known Exploited Vulnerabilities ( KEV ) catalog, based on evidence of active exploitation in the wild. The vulnerability in question is CVE-2021-44207 (CVSS score: 8.1), a case of hard-coded, static credentials in Acclaim USAHERDS that could allow an attacker to ultimately execute arbitrary code on susceptible servers. Specifically, it concerns the use of static ValidationKey and DecryptionKey values in version 7.4.0.1 and prior that could be weaponized to achieve remote code execution on the server that runs the application. That said, an attacker would have to leverage some other means to obtain the keys in the first place. "These keys are used to provide security for the application ViewState," Google-owned Mandiant said in advisory for the flaw back in December 2021. "A threat actor with knowledge ...
Apache Tomcat Vulnerability CVE-2024-56337 Exposes Servers to RCE Attacks

Apache Tomcat Vulnerability CVE-2024-56337 Exposes Servers to RCE Attacks

Dec 24, 2024 Vulnerability / Zero Day
The Apache Software Foundation (ASF) has released a security update to address an important vulnerability in its Tomcat server software that could result in remote code execution (RCE) under certain conditions. The vulnerability, tracked as CVE-2024-56337 , has been described as an incomplete mitigation for CVE-2024-50379 (CVSS score: 9.8), another critical security flaw in the same product that was previously addressed on December 17, 2024. "Users running Tomcat on a case insensitive file system with the default servlet write enabled (readonly initialisation parameter set to the non-default value of false) may need additional configuration to fully mitigate CVE-2024-50379 depending on which version of Java they are using with Tomcat," the project maintainers said in an advisory last week. Both the flaws are Time-of-check Time-of-use ( TOCTOU ) race condition vulnerabilities that could result in code execution on case-insensitive file systems when the default servlet is...
AI Could Generate 10,000 Malware Variants, Evading Detection in 88% of Case

AI Could Generate 10,000 Malware Variants, Evading Detection in 88% of Case

Dec 23, 2024 Machine Learning / Threat Analysis
Cybersecurity researchers have found that it's possible to use large language models (LLMs) to generate new variants of malicious JavaScript code at scale in a manner that can better evade detection. "Although LLMs struggle to create malware from scratch, criminals can easily use them to rewrite or obfuscate existing malware, making it harder to detect," Palo Alto Networks Unit 42 researchers said in a new analysis. "Criminals can prompt LLMs to perform transformations that are much more natural-looking, which makes detecting this malware more challenging." With enough transformations over time, the approach could have the advantage of degrading the performance of malware classification systems, tricking them into believing that a piece of nefarious code is actually benign. While LLM providers have increasingly enforced security guardrails to prevent them from going off the rails and producing unintended output, bad actors have advertised tools like WormGPT...
