The maintainers of Python Package Index (PyPI), the official third-party software repository for the Python programming language, have temporarily disabled the ability for users to sign up and upload new packages until further notice. "The volume of malicious users and malicious projects being created on the index in the past week has outpaced our ability to respond to it in a timely fashion, especially with multiple PyPI administrators on leave," the admins  said  in a notice published on May 20, 2023. No additional details about the nature of the malware and the threat actors involved in publishing those rogue packages to PyPI were disclosed. The decision to freeze new user and project registrations comes as software registries such as PyPI have proven time and time again to be a popular target for attackers looking to poison the software supply chain and compromise developer environments. Earlier this week, Israeli cybersecurity startup Phylum  uncovered  an...

The identity of the second threat actor behind the Golden Chickens malware has been uncovered courtesy of a "fatal" operational security blunder, cybersecurity firm eSentire said. The individual in question, who lives in Bucharest, Romania, has been given the codename Jack. He is one of the two criminals operating an account on the Russian-language Exploit.in forum under the name "badbullzvenom," the other being " Chuck from Montreal ." eSentire characterized Jack as the true mastermind behind Golden Chickens. Evidence unearthed by the Canadian company shows that he is also listed as the owner of a vegetable and fruit import and export business. "Like 'Chuck from Montreal,' 'Jack' uses multiple aliases for the underground forums, social media, and Jabber accounts, and he too has gone to great lengths to disguise himself," eSentire researchers Joe Stewart and Keegan Keplinger said . "'Jack' has taken great pa...

The notorious cybercrime group known as FIN7 has been observed deploying  Cl0p  (aka Clop) ransomware, marking the threat actor's first ransomware campaign since late 2021. Microsoft, which detected the activity in April 2023, is tracking the financially motivated actor under its new taxonomy  Sangria Tempest . "In these recent attacks, Sangria Tempest uses the PowerShell script POWERTRASH to load the Lizar post-exploitation tool and get a foothold into a target network," the company's threat intelligence team  said . "They then use OpenSSH and Impacket to move laterally and deploy Clop ransomware." FIN7  (aka Carbanak, ELBRUS, and ITG14) has been linked to other ransomware families such as Black Basta, DarkSide, REvil, and LockBit, with the threat actor acting as a precursor for Maze and Ryuk ransomware attacks.  Active since at least 2012, the group has a  track record  of  targeting  a broad spectrum of organizations spanning so...

The U.S. Cybersecurity and Infrastructure Security Agency (CISA) has warned of active exploitation of a medium-severity flaw affecting Samsung devices. The issue, tracked as  CVE-2023-21492  (CVSS score: 4.4), impacts select Samsung devices running Android versions 11, 12, and 13. The South Korean electronics giant described the issue as an information disclosure flaw that could be exploited by a privileged attacker to bypass address space layout randomization ( ASLR ) protections. ASLR is a  security technique  that's designed to thwart memory corruption and code execution flaws by obscuring the location of an executable in a device's memory. Samsung, in an  advisory  released this month, said it was "notified that an exploit for this issue had existed in the wild," adding it was privately disclosed to the company on January 17, 2023. Other details about how the flaw is being exploited are currently not known, but vulnerabilities in Samsung phones h...

Google has announced plans to officially flip the switch on its twice-delayed  Privacy Sandbox  initiatives as it slowly works its way to deprecate support for third-party cookies in Chrome browser. To that end, the search and advertising giant said it intends to phase out third-party cookies for 1% of Chrome users globally in the first quarter of 2024. "This will support developers in conducting real world experiments that assess the readiness and effectiveness of their products without third-party cookies," Anthony Chavez, vice president of Privacy Sandbox at Google,  said . Prior to rolling this out, Google said it would introduce the ability for third-party developers to simulate the process for a configurable subset of their users (up to 10%) in Q4 2023. Google further emphasized that the plans have been designed and developed with regulatory oversight and input from the U.K.'s Competition and Markets Authority ( CMA ), which is overseeing the implementation to...

Active Directory (AD) is among the oldest pieces of software still used in the production environment and can be found in most organizations today. This is despite the fact that its historical security gaps have never been amended. For example, because of its inability to apply any security measures beyond checking for a password and username match, AD (as well the resources it manages) is dangerously exposed to the use of compromised credentials. Furthermore, this exposure is not confined to the on-prem environment. The common practice of syncing passwords between AD and the cloud identity provider means any AD breach is a potential risk to the SaaS environment as well. In this article, we’ll explore AD’s inherent security weaknesses and examine their scope and potential impact. We'll then learn how Silverfort’s Unified Identity Protection platform can address these weaknesses at their root and provide organizations using AD with the resiliency they need to thwart identity threa...
