Introduction:
In April 2023, the cybersecurity landscape was shaken when a critical flaw in Zyxel devices was exposed, leading to a terrifying surge in DDoS botnets. These relentless attacks swiftly exploited the vulnerability, gaining remote control over vulnerable systems and causing havoc across continents. Zyxel, a leading manufacturer of networking devices like routers, switches, and firewalls, found itself at the center of this nightmare. In this article, we delve into the world of DDoS attacks and offer crucial insights into safeguarding your digital assets. At Armoryze, our mission is to empower you with confidence as we provide top-notch web application and API protection services for Zyxel devices and equipment. Global Scale Exploitation: The consequences of the Zyxel flaw were alarming, transcending geographical boundaries. Fortinet FortiGuard Labs researcher, Cara Lin, revealed the grim reality: DDoS attacks were not confined to specific regions but had penetrated Central America, North America, East Asia, and South Asia. The flaw responsible for this chaos was CVE-2023-28771, boasting a menacing CVSS score of 9.8. It proved to be a command injection vulnerability, mercilessly enabling unauthorized actors to invade systems with specially crafted packets. Multiple DDoS Botnets Seize the Opportunity: The gravity of the situation became evident when the Shadow Server Foundation issued a warning that the flaw had been actively exploited to create a botnet similar to Mirai since at least May 26, 2023. This unfortunate trend indicates an increasing abuse targeting servers with unpatched software. Multiple actors seized this opportunity to breach vulnerable hosts and assemble them into a botnet capable of launching devastating DDoS attacks against other targets. Among these botnets were Mirai variants, including Dark.IoT, and a newly identified one named Katana. These powerful botnets were capable of launching DDoS attacks using both TCP (Transmission Control Protocol) and UDP (User Datagram Protocol) protocols. TCP ensures reliable, ordered data delivery for critical apps like web browsing, while UDP provides connectionless, best-effort delivery for real-time apps like video streaming. Sophisticated Surge in DDoS Attacks: During the second quarter of 2023, Cloudflare's analysis revealed a concerning rise in the sophistication of DDoS attacks. Threat actors developed new techniques to evade detection by cleverly mimicking browser behavior while keeping their attack rates-per-second low. Additionally, attackers employed DNS laundering attacks to conceal malicious traffic through reputable recursive DNS resolvers. They also orchestrated hyper-volumetric DDoS attacks using virtual machine botnets. In a DNS Laundering attack, the threat actor queries subdomains of the victim's DNS server-managed domain. The subdomain prefix is randomized and used only a couple of times during the attack. This randomization prevents recursive DNS servers from having cached responses, leading them to forward the query to the victim's authoritative DNS server. Consequently, the authoritative DNS server is overwhelmed with a barrage of queries, rendering it incapable of handling legitimate ones and potentially crashing altogether. Understanding DDoS Attacks: To effectively defend against DDoS attacks, it is crucial to understand their nature. These attacks aim to disrupt the flow of traffic to specific servers, services, or networks by overwhelming them with excessive internet traffic. The prevalent types typically encompass volumetric, protocol-based, and application-layer attacks. At Armoryze, we offer comprehensive web application and API protection services designed to counter each of these threats. 10 Ways to Prevent a DDoS Attack: While no single solution guarantees complete prevention of DDoS attacks, implementing certain measures can significantly reduce the risk. Here are ten effective tips to safeguard your organization:
Rise of Pro-Russian Hacktivist Groups Fuels DDoS Surge: The rise in DDoS attacks can be attributed, in part, to the emergence of pro-Russian hacktivist groups like KillNet, REvil, and Anonymous Sudan. These groups have increasingly targeted entities in the U.S. and Europe. Armoryze is well-prepared to tackle such threats and fortify your organization's cybersecurity defense.

In the realm of cybersecurity, cybercriminals have found a potent tool in their pursuit of illicit gains. By exploiting known vulnerabilities within Microsoft Word, they have launched a sophisticated attack campaign that deploys the infamous LokiBot malware. This security article sheds light on the tactics employed by these threat actors and the potential risks posed to Windows systems.
LokiBot: A Persistent Information Stealer LokiBot, also known as Loki PWS, is a notorious information-stealing Trojan that has been active since 2015. This malware specifically targets Windows systems and has gained notoriety for its ability to extract sensitive data from compromised machines. As time has passed, LokiBot has evolved, and its capabilities have become more sophisticated, allowing cybercriminals to utilize it as a potent tool for data exfiltration. Once LokiBot infects a system, it works silently in the background, covertly collecting valuable information from the victim's machine. This can include sensitive personal data, login credentials, financial information, and even data from cryptocurrency wallets. LokiBot is designed to operate stealthily, evading detection by security measures and remaining persistent on the compromised system. The Exploitation Technique: A recent campaign, detected in May 2023, leveraged two specific vulnerabilities: CVE-2021-40444 and CVE-2022-30190 (also known as Follina). In this technique, hackers sent fake emails or messages to trick people into downloading harmful files using Microsoft Word documents. The unsuspecting users were lured into opening these files, which caused their computers to be compromised. The Attack Chain: Variant 1: In the first variant of the attack, a Word document exploits CVE-2021-40444 by embedding an external GoFile link within an XML file. This link leads to the download of an HTML file, which, in turn, exploits Follina to initiate the download of an injector module. This injector, written in Visual Basic, decrypts and launches the LokiBot malware. To evade detection, the injector incorporates techniques to identify the presence of debuggers and virtualized environments. Variant 2: A second variant, discovered later in May, employs a Word document containing a VBA script that instantly executes a macro upon opening. By utilizing functions such as "Auto_Open" and "Document_Open," the macro script acts as a conduit to deliver an interim payload from a remote server. This payload, functioning as an injector, loads LokiBot and establishes a connection with a command-and-control (C2) server. LokiBot's Capabilities and Impact: LokiBot is a highly capable malware that distinguishes itself from an Android banking trojan with a similar name. Its extensive range of capabilities includes keystroke logging, capturing screenshots, harvesting login credentials from web browsers, and extracting data from various cryptocurrency wallets. As a well-established and prevalent malware, LokiBot poses a significant risk to the security of sensitive information. Attackers continuously refine their initial access methods, enabling the malware to spread efficiently and infect systems, making it a persistent and dangerous threat. Top 3 Safety Measures to Protect Against LokiBot:
