Malvertising Group Harnesses WebKit 0-Day to Redirect Users to Scam Sites

February 17, 2021

A malvertising collective known as “ScamClub” has exploited a zero-day vulnerability in WebKit-based browsers to inject malicious payloads that redirect users to fraudulent gift card scam websites. The attacks, first identified by the advertising security firm Confiant in late June 2020, took advantage of a bug (CVE-2021–1801) that allowed malicious actors to circumvent the iframe sandboxing policy in the browser engine used by Safari and Google Chrome on iOS, enabling them to execute harmful code. This technique specifically targeted the way WebKit manages JavaScript event listeners, allowing attackers to escape the sandbox of an ad’s inline frame even with the “allow-top-navigation-by-user-activation” attribute in place, which typically prevents redirection unless an event occurs within the iframe. To validate this approach, researchers created a simple HTML file featuring a cross-origin sandboxed iframe, along with an external button…

Malware / Vulnerability

The cybercriminal organization known as EncryptHub is continuing to take advantage of a recently patched vulnerability in Microsoft Windows to deliver harmful payloads. Trustwave SpiderLabs has reported observing an EncryptHub campaign that combines social engineering tactics with the exploitation of a flaw in the Microsoft Management Console (MMC) framework (CVE-2025-26633, also referred to as MSC EvilTwin), initiating the infection process through a malicious Microsoft Console (MSC) file. According to Trustwave researchers Nathaniel Morales and Nikita Kazymirskyi, “These actions are part of a larger, ongoing wave of malicious activity blending social engineering with technical exploitation to circumvent security defenses and gain control of internal networks.” EncryptHub, also recognized as LARVA-208 and Water Gamayun, is a Russian hacking group that first emerged in mid-2024. Operating at a high pace, this financially motivated team is known for using various strategies, including fraudulent job postings…

Cisco Issues Security Updates for Critical Vulnerabilities in Its Products

February 26, 2021

Cisco has released a critical security patch for a severe vulnerability in its Application Centric Infrastructure (ACI) Multi-Site Orchestrator (MSO). This flaw potentially enables unauthenticated remote attackers to bypass authentication on compromised devices. According to a recent advisory from the company, “An attacker could exploit this vulnerability by sending a crafted request to the affected API.” A successful exploit could allow the attacker to obtain a token with administrator-level privileges, enabling authentication to the affected MSO and Cisco Application Policy Infrastructure Controller (APIC) devices. Identified as CVE-2021-1388, this vulnerability scores a 10 (out of 10) on the CVSS vulnerability scale and arises from improper token validation in an API endpoint of the Cisco ACI MSO installed on the Application Services Engine. It impacts ACI MSO versions running on the 3.0 software release. The ACI Multi-Site Orchestrator enables customers to monitor and manage their network infrastructure effectively.

WikiLeaks Under Siege: DDoS Attack Strikes Again

Dec 01, 2010

WikiLeaks experienced a significant distributed denial of service (DDoS) attack on Tuesday morning, as detailed by Fast Company. This assault was more severe than a previous one on Sunday, yet it failed to completely disrupt the site. The perpetrator, a hacker known as “The Jester,” took credit for the cyber attack that targeted WikiLeaks just before it released a trove of classified U.S. embassy cables.

The Jester, an ex-soldier, defended his actions by alleging that WikiLeaks was “endangering the lives of our troops, ‘other assets,’ and foreign relations.” After his military service, he positioned himself as a “hacktivist for good,” aiming to combat terrorism and groups linked to Islamic extremism. Cybersecurity expert Mikko Hypponen from F-Secure expressed belief that The Jester was indeed the mastermind behind the attack.
