Multiple security vulnerabilities have been disclosed in popular package managers that, if potentially exploited, could be abused to run arbitrary code and access sensitive information, including source code and access tokens, from compromised machines. It's, however, worth noting that the flaws require the targeted developers to handle a malicious package in conjunction with one of the affected package managers. "This means that an attack cannot be launched directly against a developer machine from remote and requires that the developer is tricked into loading malformed files," SonarSource researcher Paul Gerste  said . "But can you always know and trust the owners of all packages that you use from the internet or company-internal repositories?" Package managers refer to  systems  or a set of tools that are used to automate installing, upgrading, configuring third-party dependencies required for developing applications. While there are inherent  security ...

The Russian government has established its own TLS certificate authority ( CA ) to address issues with accessing websites that have arisen in the wake of sanctions imposed by the west following the country's unprovoked military invasion of Ukraine. According to a message posted on the  Gosuslugi  public services portal, the Ministry of Digital Development is expected to provide a domestic replacement to handle the issuance and renewal of TLS certificates should they get revoked or expired. The service is offered to all legal entities operating in Russia, with the certificates delivered to site owners upon request within 5 working days. TLS certificates are used to digitally bind a cryptographic key to an organization's details, enabling web browsers to confirm the domain's authenticity and ensure that the communication between a client computer and the target website is secure. The proposal comes as companies like DigiCert have been restricted from doing business in ...

Meta Platforms' WhatsApp and Cloudflare have banded together for a new initiative called Code Verify to validate the authenticity of the messaging service's web app on desktop computers. Available in the form of a Chrome and Edge  browser extension , the  open-source add-on  is designed to "automatically verif[y] the authenticity of the WhatsApp Web code being served to your browser," Facebook  said  in a statement. The goal with Code Verify is to confirm the integrity of the web application and ensure that it hasn't been tampered with to inject malicious code. The social media company is also planning to release Firefox and Safari plugins to achieve the same level of security across browsers. The system works with Cloudflare acting as a third-party audit to compare the cryptographic hash of WhatsApp Web's JavaScript code that's shared by Meta with that of a locally computed hash of the code running on the browser client. Code Verify is also meant t...

Is Managing Customer Logins and Data Giving You Headaches? You're Not Alone! Today, we all expect super-fast, secure, and personalized online experiences.

If you're dealing with logins, data privacy, bringing new users on board, or building digital trust, this webinar is for you . Join us for " Navigating Customer Identity in the AI Era ," where we'll dive into the Auth0 2025 Customer Identity Trends Report . We'll show you what's working, what's not, and how to tweak your strategy for the year ahead. In just one session, you'll get practical answers to real-world challenges like: How AI is changing what users expect – and where they're starting to push ba...

The Iranian state-sponsored threat actor known as MuddyWater has been attributed to a new swarm of attacks targeting Turkey and the Arabian Peninsula with the goal of deploying remote access trojans (RATs) on compromised systems. "The MuddyWater supergroup is highly motivated and can use unauthorized access to conduct espionage, intellectual property theft, and deploy ransomware and destructive malware in an enterprise," Cisco Talos researchers Asheer Malhotra, Vitor Ventura, and Arnaud Zobec  said  in a report published today. The group, which has been active since at least 2017, is known for its attacks on various sectors that help further advance Iran's geopolitical and national security objectives. In January 2022, the U.S. Cyber Command attributed the actor to the country's Ministry of Intelligence and Security (MOIS). MuddyWater is also believed to be a "conglomerate of  multiple teams  operating independently rather than a single threat actor group,...

Researchers have disclosed a new technique that could be used to circumvent existing hardware mitigations in modern processors from Intel, AMD, and Arm, and stage  speculative execution  attacks such as Spectre to leak sensitive information from host memory. Attacks like  Spectre  are designed to break the isolation between different applications by taking advantage of an  optimization technique  called speculative execution in CPU hardware implementations to trick programs into accessing arbitrary locations in memory and thus leak their secrets. While chipmakers have incorporated both software and hardware  defenses , including  Retpoline  as well as safeguards like Enhanced Indirect Branch Restricted Speculation ( eIBRS ) and  Arm   CSV2 , the latest method demonstrated by VUSec researchers aims to get around all these protections. Called  Branch History Injection  (BHI or Spectre-BHB), it's a new variant of Spectr...

Yaroslav Vasinskyi , a Ukrainian national, linked to the Russia-based  REvil ransomware group  has been extradited to the U.S. to face charges for his role in carrying out the file-encrypting malware attacks against several companies, including Kaseya last July. The 22-year-old had been previously arrested in Poland in October 2021, prompting the U.S. Justice Department (DoJ) to  file charges  of conspiracy to commit fraud and related activity in connection with computers, damage to protected computers, and conspiracy to commit money laundering. Ransomware is the digital equivalent of extortion wherein cybercrime actors encrypt victims' data and take it hostage in return for a monetary payment to recover the data, failing which the stolen information is published online or sold to other third-parties. According to the DoJ, in addition to the headline-grabbing attacks on JBS and Kaseya, REvil is said to have propagated its infection to more than 175,000 computer...

The insidious Emotet botnet, which staged a return in November 2021 after a 10-month-long hiatus, is once again exhibiting signs of steady growth, amassing a swarm of over 100,000 infected hosts for perpetrating its malicious activities. "While Emotet has not yet attained the same scale it once had, the botnet is showing a strong resurgence with a total of approximately 130,000 unique bots spread across 179 countries since November 2021," researchers from Lumen's Black Lotus Labs  said  in a report. Emotet, prior to its  takedown  in late January 2021 as part of a coordinated law enforcement operation dubbed "Ladybird," had infected no fewer than 1.6 million devices globally, acting as a conduit for cybercriminals to install other types of malware, such as banking trojans or ransomware, onto compromised systems. The malware  officially resurfaced  in November 2021  using TrickBot  as a delivery vehicle, with the latter  shuttering its at...
