Russian Hackers Exploit Email and VPN Vulnerabilities to Spy on Ukraine Aid Logistics

Russian Hackers Exploit Email and VPN Vulnerabilities to Spy on Ukraine Aid Logistics

May 21, 2025 Cyber Espionage / Vulnerability
Russian cyber threat actors have been attributed to a state-sponsored campaign targeting Western logistics entities and technology companies since 2022. The activity has been assessed to be orchestrated by APT28 (aka BlueDelta, Fancy Bear, or Forest Blizzard), which is linked to the Russian General Staff Main Intelligence Directorate (GRU) 85th Main Special Service Center, Military Unit 26165. Targets of the campaign include companies involved in the coordination, transport, and delivery of foreign assistance to Ukraine, according to a joint advisory released by agencies from Australia, Canada, Czechia, Denmark, Estonia, France, Germany, the Netherlands, Poland, the United Kingdom, and the United States. "This cyber espionage-oriented campaign targeting logistics entities and technology companies uses a mix of previously disclosed TTPs and is likely connected to these actors' wide scale targeting of IP cameras in Ukraine and bordering NATO nations," the bulletin said...
AWS Default IAM Roles Found to Enable Lateral Movement and Cross-Service Exploitation

AWS Default IAM Roles Found to Enable Lateral Movement and Cross-Service Exploitation

May 20, 2025 Cloud Security / Vulnerability
Cybersecurity researchers have discovered risky default identity and access management (IAM) roles impacting Amazon Web Services that could open the door for attackers to escalate privileges, manipulate other AWS services, and, in some cases, even fully compromise AWS accounts. "These roles, often created automatically or recommended during setup, grant overly broad permissions, such as full S3 access," Aqua researchers Yakir Kadkoda and Ofek Itach said in an analysis. "These default roles silently introduce attack paths that allow privilege escalation, cross-service access, and even potential account compromise." The cloud security firm said it identified security issues in default IAM roles created by AWS services like SageMaker, Glue, EMR, and Lightsail. A similar flaw has also been unearthed in a popular open-source framework called Ray, which automatically creates a default IAM role (ray-autoscaler-v1) with the AmazonS3FullAccess policy. What's concer...

RVTools Official Site Hacked to Deliver Bumblebee Malware via Trojanized Installer

May 19, 2025 Malware / Supply Chain Attack
The official site for RVTools has been hacked to serve a compromised installer for the popular VMware environment reporting utility. "Robware.net and RVTools.com are currently offline. We are working expeditiously to restore service and appreciate your patience," the company said in a statement posted on its website. "Robware.net and RVTools.com are the only authorized and supported websites for RVTools software. Do not search for or download purported RVTools software from any other websites or sources." The development comes after security researcher Aidan Leon revealed that an infected version of the installer downloaded from the website was being used to sideload a malicious DLL that turned out to be a known malware loader called Bumblebee . It's currently not known how long the trojanized version of RVTools had been available for download and how many had installed it before the site was taken offline. In the interim, users are recommended to veri...

Researchers Expose New Intel CPU Flaws Enabling Memory Leaks and Spectre v2 Attacks

Researchers Expose New Intel CPU Flaws Enabling Memory Leaks and Spectre v2 Attacks

May 16, 2025 Hardware Security / Vulnerability
Researchers at ETH Zürich have discovered yet another security flaw that they say impacts all modern Intel CPUs and causes them to leak sensitive data from memory, showing that the vulnerability known as Spectre continues to haunt computer systems after more than seven years. The vulnerability, referred to as Branch Privilege Injection (BPI), "can be exploited to misuse the prediction calculations of the CPU (central processing unit) in order to gain unauthorized access to information from other processor users," ETH Zurich said . Kaveh Razavi, head of the Computer Security Group (COMSEC) and one of the authors of the study, said the shortcoming affects all Intel processors, potentially enabling bad actors to read the contents of the processor's cache and the working memory of another user of the same CPU. The attack leverages what's called Branch Predictor Race Conditions ( BPRC ) that emerge when a processor switches between prediction calculations for two use...
Pen Testing for Compliance Only? It's Time to Change Your Approach

Pen Testing for Compliance Only? It's Time to Change Your Approach

May 15, 2025 Compliance / Penetration Testing
Imagine this: Your organization completed its annual penetration test in January, earning high marks for security compliance. In February, your development team deployed a routine software update. By April, attackers had already exploited a vulnerability introduced in that February update, gaining access to customer data weeks before being finally detected. This situation isn't theoretical: it plays out repeatedly as organizations realize that point-in-time compliance testing can't protect against vulnerabilities introduced after the assessment. According to Verizons 2025 Data Breach Investigation Report , the exploitation of vulnerabilities rose 34% year-over-year. While compliance frameworks provide important security guidelines, companies need continuous security validation to identify and remediate new vulnerabilities before attackers can exploit them. Here's what you need to know about pen testing to meet compliance standards — and why you should adopt continuous penetratio...

Russia-Linked APT28 Exploited MDaemon Zero-Day to Hack Government Webmail Servers

May 15, 2025 Vulnerability / Email Security
A Russia-linked threat actor has been attributed to a cyber espionage operation targeting webmail servers such as Roundcube, Horde, MDaemon, and Zimbra via cross-site scripting (XSS) vulnerabilities, including a then-zero-day in MDaemon, according to new findings from ESET. The activity, which commenced in 2023, has been codenamed Operation RoundPress by the Slovak cybersecurity company. It has been attributed with medium confidence to the Russian state-sponsored hacking group tracked as APT28, which is also referred to as BlueDelta, Fancy Bear, Fighting Ursa, Forest Blizzard, FROZENLAKE, Iron Twilight, ITG05, Pawn Storm, Sednit, Sofacy, and TA422. "The ultimate goal of this operation is to steal confidential data from specific email accounts," ESET researcher Matthieu Faou said in a report shared with The Hacker News. "Most victims are governmental entities and defense companies in Eastern Europe, although we have observed governments in Africa, Europe, and South ...
