Russian hackers have found a way to bypass Gmail's multi-factor authentication (MFA) to conduct targeted attacks against academics and critics engaging with Russia discussions. According to Google Threat Intelligence Group (GTIG), the hackers are using stolen app passwords obtained through sophisticated and personalized social engineering attacks. These attacks involve posing as U.S. Department of State officials to build rapport with targets, eventually convincing them to create and share app-specific passwords.
App passwords are 16-digit codes that Google generates to allow certain apps or devices to access a Google Account, bypassing the usual second verification step of MFA. While useful for older or less secure apps that can't handle MFA, app passwords lack the extra layer of security, making them vulnerable to theft or phishing. In one instance, the attackers, tracked as UNC6293 and believed to be state-sponsored, contacted a target under the guise of a State Department representative, inviting them to a consultation in a private online conversation, further lending credibility by CCing four @state.gov accounts. This campaign, which took place between April and early June, involved meticulously crafted phishing messages that didn't rush the target into immediate action. Instead, the hackers focused on building trust through personalized emails and invitations to private conversations, using spoofed '@state.gov' addresses in the CC field to build credibility. Keir Giles, a prominent British researcher on Russia, was one such target. Google's researchers uncovered the slow-paced nature attackers used to build rapports with their victims, often sending them personalized emails and inviting them to private conversations or meetings.

Amidst escalating regional conflicts, Iran has taken the drastic measure of shutting down internet access for its citizens, a move the government defends as a necessary precaution against Israeli cyberattacks. This disruption has severely impacted communication within the country, leaving Iranians abroad unable to connect with loved ones. One such individual, Amir Rashidi, expressed his anxiety, stating he hadn't heard from his family in two days and was relying on someone else for updates. The situation highlights the growing intersection of cyber warfare and real-world consequences for civilians.
The internet blackout is not the first instance of Iran limiting connectivity. In the past, similar restrictions were imposed during periods of political unrest, such as protests in 2019 and 2022. These shutdowns are implemented by pushing people towards domestic apps, which are often less secure, while also severely restricting access to vital information. Experts like Doug Madory from Kentik have documented significant drops in internet connectivity within Iran following recent Israeli airstrikes, with reductions of 54% initially, followed by further declines of 49% and, subsequently, a staggering 90%. In a defensive maneuver against cyber threats, Iran is throttling its National Internet Infrastructure. The country claims it is restricting internet connectivity to counter cyber attacks amid regional conflict. The stated aim is to impede cyber intrusions and the synchronization of adversarial operations. An example of the threats Iran faces is demonstrated by the Israeli-linked hackers who seized and burned $90 million from Iran's Nobitex exchange. Recommended read:

A new Kerberos relay attack, identified as CVE-2025-33073, has been discovered that bypasses NTLM protections and allows attackers to escalate privileges to NT AUTHORITY\SYSTEM. This reflective Kerberos relay attack involves coercing a host to authenticate, intercepting the Kerberos ticket, and relaying it back to the same host, effectively exploiting misconfigurations and the lack of enforced SMB signing. RedTeam Pentesting discovered the vulnerability in January 2025 and disclosed it to Microsoft in an extensive whitepaper.
Microsoft addressed this vulnerability as part of the June 2025 Patch Tuesday. Technical analyses of CVE-2025-33073 have been published by RedTeam Pentesting and Synacktiv. The vulnerability is rooted in how the SMB client negotiates Kerberos authentication. When the SMB client has negotiated Kerberos instead of NTLM, a session key is inserted into a global list, KerbSKeyList, without proper checks, allowing attackers to reuse a subkey under specific conditions to forge a privileged token. The attack begins with authentication coercion via SMB, tricking a victim machine into connecting to a malicious SMB server. The server forces the client into Kerberos authentication, generates a subkey, logs it into KerbSKeyList with privileged token data, and forges a valid AP-REQ ticket using the subkey. The SMB client accepts and validates the forged ticket, leading to the generation of a SYSTEM token and granting administrative privileges. A proof-of-concept exploit has been made available to demonstrate the vulnerability's potential. Recommended read:

Elastic Security Labs has identified a new information stealer called EDDIESTEALER, a Rust-based malware distributed through fake CAPTCHA campaigns. These campaigns trick users into executing malicious PowerShell scripts, which then deploy the infostealer onto their systems. EDDIESTEALER is hosted on multiple adversary-controlled web properties and employs the ClickFix social engineering tactic, luring unsuspecting individuals with the promise of CAPTCHA verification. The malware aims to harvest sensitive data, including credentials, browser information, and cryptocurrency wallet details.
This attack chain begins with threat actors compromising legitimate websites, injecting malicious JavaScript payloads that present bogus CAPTCHA check pages. Users are instructed to copy and paste a PowerShell command into their Windows terminal as verification, which retrieves and executes a JavaScript file called gverify.js. This script, in turn, fetches the EDDIESTEALER binary from a remote server, saving it in the downloads folder with a pseudorandom filename. The malware dynamically retrieves configuration data from a command-and-control server, allowing it to adapt its behavior and target specific programs. EDDIESTEALER is designed to gather system metadata and siphon data of interest from infected hosts, including cryptocurrency wallets, web browsers, password managers, FTP clients, and messaging apps like Telegram. The malware incorporates string encryption, a custom WinAPI lookup mechanism, and a mutex to prevent multiple instances from running. It also includes anti-sandbox checks and a self-deletion technique using NTFS Alternate Data Streams to evade detection.

A new Windows Remote Access Trojan (RAT) has been discovered that employs a novel technique to evade detection. The malware corrupts its own DOS and PE headers, making it significantly more difficult for security tools to analyze and reconstruct the malicious code. This method obstructs forensic analysis and allows the RAT to operate stealthily on compromised Windows machines for extended periods, in some cases, for weeks before being detected. The FortiGuard Incident Response Team conducted a detailed investigation into this malware.
The Fortinet team managed to obtain a memory dump of the live malware process (dllhost.exe process PID 8200) and a complete 33GB memory dump of the compromised system. By meticulously replicating the compromised environment, they were able to revive the dumped malware in a controlled setting. This allowed them to observe its operations and communication patterns. The researchers had to manually identify the malware's entry point, allocate memory, and resolve API addresses through debugging, address relocation, and parameter adjustments to emulate the malware's behaviour in a lab setting. Once operational, the malware was found to communicate with a command-and-control (C2) server at rushpaperscom over port 443, utilizing TLS encryption. Fortinet analysts identified the malware's use of Windows API functions like SealMessage() and DecryptMessage() to handle encrypted traffic, along with an additional layer of custom encryption. Analysis confirms that the malware is a RAT, allowing attackers to capture screenshots, manipulate system services, and establish connections with other clients. Recommended read:

A new cyber-espionage campaign has been uncovered, targeting public sector organizations in Tajikistan. The threat actor behind this campaign is TAG-110, a group linked to Russia and also known as UAC-0063 and APT28 (BlueDelta). Recorded Future’s Insikt Group discovered that TAG-110 is using macro-enabled Microsoft Word templates (.dotm files) to gain access to and exfiltrate intelligence from Tajik government, educational, and research institutions, particularly those involved in military affairs or electoral processes. This campaign reflects Russia’s strategic interest in Central Asia through intelligence-gathering operations.
These malicious Word templates are deployed through phishing lures disguised as official Tajik government documents. The templates are saved in the Microsoft Word STARTUP folder, ensuring automatic execution each time Word is launched. This tactic represents a shift from TAG-110’s previous use of HTA-based payloads like HATVIBE. The two malicious documents identified are themed around radiation safety for Tajikistan’s armed forces and election schedules in Dushanbe. Upon execution, the embedded VBA macros collect system metadata such as username, computer name, language, and resolution. This data is then sent to a hardcoded command-and-control (C2) server. The macros also establish persistence by copying themselves to the %APPDATA%\Microsoft\Word\STARTUP\ directory. Researchers state that this evolution highlights a tactical shift prioritizing persistence. The use of .dotm files and VBA macros allows TAG-110 to maintain a stealthy presence and collect data from compromised systems, turning them into surveillance nodes. Recommended read:

Signal, the privacy-focused messaging application, has taken action to block Microsoft's controversial Recall feature from capturing screenshots of its desktop app content on Windows 11. Citing privacy concerns over Recall's ability to automatically take screenshots of on-screen activity, Signal has implemented a "screen security" setting, enabled by default, that leverages Digital Rights Management (DRM) to prevent the tool from accessing and recording private conversations. This move comes as Signal expresses discontent with Microsoft's approach, arguing that Recall lacks sufficient developer controls to exclude specific apps and protect sensitive information.
Microsoft's Recall feature, designed for Copilot+ PCs, works by continuously taking screenshots and creating a searchable database of user activity. Signal argues that this poses a significant risk to the privacy of its users, as private conversations could be inadvertently captured and stored. By implementing DRM, Signal sets a flag on its application window that instructs Recall, and any other screenshotting application, to ignore its content. While Signal acknowledges this is a blunt tool that may interfere with accessibility software, it believes Microsoft left them with no other choice. Signal has criticized Microsoft for not providing developers with the necessary tools to manage how Recall interacts with their applications. The messaging app argues that it shouldn't have to resort to using DRM "content protection hacks" to safeguard user privacy. Signal hopes that AI teams building systems like Recall will carefully consider the privacy implications and avoid forcing apps to use workarounds to protect the integrity of their services. They want the AI teams to know that this will potentially affect accessibility options like screen readers. Recommended read:
