The Russian nation-state threat actor known as Secret Blizzard has been observed orchestrating a new cyber espionage campaign targeting foreign embassies located in Moscow by means of an adversary-in-the-middle ( AitM ) attack at the Internet Service Provider (ISP) level and delivering a custom malware dubbed ApolloShadow. "ApolloShadow has the capability to install a trusted root certificate to trick devices into trusting malicious actor-controlled sites, enabling Secret Blizzard to maintain persistence on diplomatic devices, likely for intelligence collection," the Microsoft Threat Intelligence team said in a report shared with The Hacker News. The activity is assessed to be ongoing since at least 2024, with the campaign posing a security risk to diplomatic personnel relying on local ISPs or telecommunications services in Russia. Secret Blizzard (formerly Krypton), affiliated with the Russian Federal Security Service, is also tracked by the broader cybersecurity commu...

Cybersecurity researchers have disclosed details of a new phishing campaign that conceals malicious payloads by abusing link wrapping services from Proofpoint and Intermedia to bypass defenses. "Link wrapping is designed by vendors like Proofpoint to protect users by routing all clicked URLs through a scanning service, allowing them to block known malicious destinations at the moment of click," the Cloudflare Email Security team said . "While this is effective against known threats, attacks can still succeed if the wrapped link hasn't been flagged by the scanner at click time." The activity, observed over the last two months, once again illustrates how threat actors find different ways to leverage legitimate features and trusted tools to their advantage and perform malicious actions, in this case, redirecting victims to Microsoft 365 phishing pages. It's noteworthy that the abuse of link wrapping involves the attackers gaining unauthorized access to em...

The North Korea-linked threat actor known as UNC4899 has been attributed to attacks targeting two different organizations by approaching their employees via LinkedIn and Telegram.

The financially motivated threat actor known as UNC2891 has been observed targeting Automatic Teller Machine (ATM) infrastructure using a 4G-equipped Raspberry Pi as part of a covert attack. The cyber-physical attack involved the adversary leveraging their physical access to install the Raspberry Pi device and have it connected directly to the same network switch as the ATM, effectively placing it within the target bank's network, Group-IB said. It's currently not known how this access was obtained. "The Raspberry Pi was equipped with a 4G modem, allowing remote access over mobile data," security researcher Nam Le Phuong said in a Wednesday report. "Using the TINYSHELL backdoor, the attacker established an outbound command-and-control (C2) channel via a Dynamic DNS domain. This setup enabled continuous external access to the ATM network, completely bypassing perimeter firewalls and traditional network defenses." UNC2891 was first documented by Googl...

Security Operations Centers (SOCs) are stretched to their limits. Log volumes are surging, threat landscapes are growing more complex, and security teams are chronically understaffed. Analysts face a daily battle with alert noise, fragmented tools, and incomplete data visibility. At the same time, more vendors are phasing out their on-premises SIEM solutions, encouraging migration to SaaS models. But this transition often amplifies the inherent flaws of traditional SIEM architectures. T he Log Deluge Meets Architectural Limits SIEMs are built to process log data—and the more, the better, or so the theory goes. In modern infrastructures, however, log-centric models are becoming a bottleneck. Cloud systems, OT networks, and dynamic workloads generate exponentially more telemetry, often redundant, unstructured, or in unreadable formats. SaaS-based SIEMs in particular face financial and technical constraints: pricing models based on events per second (EPS) or flows-per-minute (FPM) ca...

Threat actors are actively exploiting a critical security flaw in " Alone – Charity Multipurpose Non-profit WordPress Theme " to take over susceptible sites. The vulnerability, tracked as CVE-2025-5394 , carries a CVSS score of 9.8. Security researcher Thái An has been credited with discovering and reporting the bug. According to Wordfence, the shortcoming relates to an arbitrary file upload affecting all versions of the plugin prior to and including 7.8.3. It has been addressed in version 7.8.5 released on June 16, 2025. CVE-2025-5394 is rooted in a plugin installation function named "alone_import_pack_install_plugin()" and stems from a missing capability check, thereby allowing unauthenticated users to deploy arbitrary plugins from remote sources via AJAX and achieve code execution. "This vulnerability makes it possible for an unauthenticated attacker to upload arbitrary files to a vulnerable site and achieve remote code execution, which is typically lev...

Cybersecurity researchers are calling attention to an ongoing campaign that distributes fake cryptocurrency trading apps to deploy a compiled V8 JavaScript (JSC) malware called JSCEAL that can capture data such as credentials and wallets. The activity leverages thousands of malicious advertisements posted on Facebook in an attempt to redirect unsuspecting victims to counterfeit sites that instruct them to install the bogus apps, according to Check Point. These ads are shared either via stolen accounts or newly created ones. "The actors separate the installer's functionality into different components and most notably move some functionality to the JavaScript files inside the infected websites," the company said in an analysis. "A modular, multi-layered infection flow enables the attackers to adapt new tactics and payloads at every stage of the operation." It's worth noting that some aspects of the activity were previously documented by Microsoft in April 2...

Cybersecurity experts have released a decryptor for a ransomware strain called FunkSec, allowing victims to recover access to their files for free. "Because the ransomware is now considered dead, we released the decryptor for public download," Gen Digital researcher Ladislav Zezula said .
