Old-school gaming consoles are seeing a resurgence, but hackers are exploiting this trend with a malware campaign called "WeedHack," which emerged in January. This malware operates on a "Malware-as-a-Service" model, allowing users to purchase it to infect victims. WeedHack functions as a remote access infostealer, compromising computers to manipulate screens, access webcams, and steal sensitive data. It propagates by enticing users with unofficial "Minecraft" mods and clients, often using videos and download links as bait. Additionally, it employs "SEO poisoning" to promote fake websites as legitimate sources for these mods on platforms like Discord and Reddit. WeedHack disguises itself as a JAR file, similar to the official "Minecraft" client, and once executed, it installs its payload from Ethereum server domains. It can insert itself into antivirus exclusion lists, evading detection, and McAfee's tests show that Windows Defender is ineffective against it. The malware collects extensive information, including Wi-Fi networks and browser cookies, and grants hackers complete control over infected computers. The WeedHack virus serves as both malware and a training ground for aspiring hackers, structured into two tiers: a free version with core capabilities and a paid subscription for advanced features. A community has formed around WeedHack, offering tutorials, a Discord server, and a website for feature requests and custom payload creation. This community aspect lowers the barrier for newcomers, particularly targeting a younger audience that may not understand online safety.

Columbia University faced a setback in its patent dispute with Gen Digital Inc. regarding U.S. Patents 8,074,115 and 8,601,322, which relate to an innovative virus detection method developed in the early 2000s. The method involved evaluating the behavior of suspicious code using an emulator and a model of expected behavior derived from data across interconnected computers. Columbia initiated legal proceedings in 2013, and after various developments, a jury awarded Columbia over million in royalties for willful infringement in 2022. However, the Federal Circuit ruled that the patent claims were not sufficiently specific and remanded the case for further examination of whether the claims could constitute an inventive concept. The ruling emphasized that patent eligibility is determined by the precise language of the claims.

On January 19, 1986, the computer virus Brain emerged, recognized as the first major global threat in cybersecurity. Created by Basit and Amjad Farooq Alvi in Lahore, Pakistan, it targeted IBM PC-compatible machines running MS-DOS and spread via floppy disks. Brain was initially intended to protect the brothers' medical software from piracy by tracking unauthorized copies. It embedded itself in the boot sector of infected computers and displayed a message with the creators' contact information. Despite its benign intent, Brain spread internationally, highlighting the potential for software to replicate and traverse borders autonomously. This event raised awareness about computer viruses and initiated discussions on antivirus solutions and the ethical responsibilities of programmers. Brain exposed vulnerabilities in early personal computers and prompted the integration of cybersecurity considerations into software design.

Bernardo Quintero sought to find the programmer behind the Virus Málaga, which had a significant impact on his life and career in cybersecurity. The virus, initially a piece of malware, sparked Quintero's interest in the field and led to the creation of VirusTotal, which was acquired by Google in 2012. This acquisition helped elevate Málaga as a tech hub in Europe. Quintero revisited the virus code and discovered a clue linking it to a programmer named Enrique, who was affectionately known as Kiki. He learned from Antonio Astorga, a source who passed away, that the virus contained a hidden message against the Basque terrorist group ETA. Astorga's legacy continues through his son, Serhiy, who has aspirations in cybersecurity and quantum computing.
