The ALPHV ransomware gang, also referred to as BlackCat, is trying to put more pressure on their victims to pay a ransom by providing an API for their leak site to increase visibility for their...
Google's security researcher Tavis Ormandy discovered a new vulnerability impacting AMD Zen2 CPUs that could allow a malicious actor to steal sensitive data, such as passwords and encryption keys, at a rate of 30KB/sec from each CPU core. After triggering an optimized exploit for the flaw, the researcher could leak sensitive data from any system operation, including those that take place in virtual machines, isolated sandboxes, containers, etc.
AMD has started issuing some patches for its processors affected by a serious silicon-level bug dubbed Zenbleed that can be exploited by rogue users and malware to steal passwords, cryptographic keys, and other secrets from software running on a vulnerable system. Exploiting Zenbleed involves abusing speculative execution, though unlike the related Spectre family of design flaws, the bug is pretty easy to exploit.
The Clop ransomware gang is copying an ALPHV ransomware gang extortion tactic by creating Internet-accessible websites dedicated to specific victims, making it easier to leak stolen data and further pressuring victims into paying a ransom. This stolen data is used as leverage in double-extortion attacks, warning victims that the data will be leaked if a ransom is not paid.
Citrix ADC zero-day exploitatation: CISA releases details about attack on CI organizationThe exploitation of the Citrix NetScaler ADC zero-day vulnerability was first spotted by a critical infrastructure organization, who reported it to the Cybersecurity and Infrastructure Security Agency. CISOs under pressure: Protecting sensitive information in the age of high employee turnoverIn this Help Net Security interview, Charles Brooks, Adjunct Professor at Georgetown University's Applied Intelligence Program and graduate Cybersecurity Programs, talks about how zero trust principles, identity access management, and managed security services are crucial for effective cybersecurity, and how implementation of new technologies like AI, machine learning, and tracking tools can enhance supply chain security.
VirusTotal apologized on Friday for leaking the information of over 5,600 customers after an employee mistakenly uploaded a CSV file containing their info to the platform last month. The data leak impacted only Premium account customers, with the uploaded file containing their names and corporate email addresses.
Non-executable files containing malware were rarely shared, and could easily and automatically be identified if you tried to share one by mistake because they lacked the tell-tale starting bytes of a typical program file. Firstly, numerous malware families sneakily store at least some of their own needed data as added information in the personal part of such files, so that trying to bowdlerise, redact or rewrite the sensitive, "Unsharable" parts of the file causes the malware to stop working, or to behave differently.
Data associated with a subset of registered customers of VirusTotal, including their names and email addresses, have leaked on the internet. The security incident, which comprises a database of 5,600 names in a 313KB file, was first disclosed by Der Spiegel and Der Standard yesterday.
Researchers at the RWTH Aachen University in Germany published a study revealing that tens of thousands of container images hosted on Docker Hub contain confidential secrets, exposing software,...
Threat landscape trends demonstrate the impressive flexibility of cybercriminals as they continually seek out fresh methods of attack, including exploiting vulnerabilities, gaining unauthorized access, compromising sensitive information, and defrauding individuals, according to the H1 2023 ESET Threat Report. ESET telemetry data also suggests that operators of the once-notorious Emotet botnet have struggled to adapt to the shrinking attack surface, possibly indicating that a different group acquired the botnet.
