A nascent Android remote access trojan called Mirax has been observed actively targeting Spanish-speaking countries, with campaigns reaching more than 220,000 accounts on Facebook, Instagram, Messenger, and Threads through advertisements on Meta. "Mirax integrates advanced Remote Access Trojan (RAT) capabilities, allowing threat actors to fully interact with compromised devices in real time," Italian online fraud prevention firm Cleafy said . "Beyond traditional RAT behavior, Mirax enhances its operational value by turning infected devices into residential proxy nodes . Leveraging SOCKS5 protocol support and Yamux multiplexing, it establishes persistent proxy channels that allow attackers to route their traffic through the victim's real IP address." Details of Mirax first emerged last month when Outpost24's KrakenLabs revealed that a threat actor going by the name "Mirax Bot" has been advertising a private malware-as-a-service (MaaS) offerin...

Banks and financial institutions in Latin American countries like Brazil and Mexico have continued to be the target of a malware family called JanelaRAT . A modified version of BX RAT, JanelaRAT is known to steal financial and cryptocurrency data associated with specific financial entities, as well as track mouse inputs, log keystrokes, take screenshots, and collect system metadata. "One of the key differences between these trojans is that JanelaRAT uses a custom title bar detection mechanism to identify desired websites in victims' browsers and perform malicious actions," Kaspersky said in a report published today. "The threat actors behind JanelaRAT campaigns continuously update the infection chain and malware versions by adding new features." Telemetry data gathered by the Russian cybersecurity vendor shows that as many as 14,739 attacks were recorded in Brazil in 2025 and 11,695 in Mexico. It's currently not known how many of these resulted in a su...

The U.S. Federal Bureau of Investigation (FBI), in partnership with the Indonesian National Police, has dismantled the infrastructure associated with a global phishing operation that leveraged an off-the-shelf toolkit called W3LL to steal thousands of victims' account credentials and attempt more than $20 million in fraud. In tandem, authorities detained the alleged developer, who has been identified as G.L, and seized key domains linked to the phishing scheme. "The takedown cuts off a major resource used by cybercriminals to gain unauthorized access to victims' accounts," the FBI said in a statement.  The W3LL phishing kit allowed criminals to mimic legitimate login pages to deceive victims into handing over their credentials, thus allowing the attackers to seize control of their accounts. The phishing kit was advertised for a fee of about $500. The phishing kit enabled its customers to deploy bogus websi...

Monday is back, and the weekend’s backlog of chaos is officially hitting the fan. We are tracking a critical zero-day that has been quietly living in your PDFs for months, plus some aggressive state-sponsored meddling in infrastructure that is finally coming to light. It is one of those mornings where the gap between a quiet shift and a full-blown incident response is basically non-existent. The variety this week is particularly nasty. We have AI models being turned into autonomous exploit engines, North Korean groups playing the long game with social engineering, and fileless malware hitting enterprise workflows. There is also a major botnet takedown and new research proving that even fiber optic cables can be used to eavesdrop on your private conversations. Skim this before your next meeting. Let’s get into it. ⚡ Threat of the Week Adobe Acrobat Reader 0-Day Under Attack   — Adobe released emergency updates to fix a critical...

The North Korean hacking group tracked as APT37 (aka ScarCruft) has been attributed to a fresh multi-stage, social engineering campaign in which threat actors approached targets on Facebook and added them as friends on the social media platform, turning the trust-building exercise into a delivery channel for a remote access trojan called RokRAT . "The threat actor used two Facebook accounts with their location set to Pyongyang and Pyongsong, North Korea, to identify and screen targets," the Genians Security Center (GSC) said in a technical breakdown of the campaign. "After building trust through friend requests, the actor moved the conversation to Messenger and used specific topics to lure targets as part of the initial social engineering stage of the attack." Central to the attack is the use of what the GSC describes as pretexting, a tactic where the threat actors aim to trick unsuspecting users into installing a dedicated PDF viewer, claiming the software...
