The threat actors behind the Windows-based  Grandoreiro  banking trojan have returned in a global campaign since March 2024 following a law enforcement takedown in January. The large-scale phishing attacks, likely facilitated by other cybercriminals via a malware-as-a-service (MaaS) model, target over 1,500 banks across the world, spanning more than 60 countries in Central and South America, Africa, Europe, and the Indo-Pacific, IBM X-Force said. While  Grandoreiro  is known primarily for its focus in Latin America, Spain, and Portugal, the expansion is likely a shift in strategy after attempts to  shut down its infrastructure  by Brazilian authorities. Going hand-in-hand with the broader targeting footprint are significant improvements to the malware itself, which indicates active development. "Analysis of the malware revealed major updates within the string decryption and domain generating algorithm (DGA), as well as the ability to use Mic...

The Russian state-sponsored hacking group tracked as APT28 has been attributed to a new Microsoft Outlook backdoor called NotDoor in attacks targeting multiple companies from different sectors in NATO member countries. NotDoor "is a VBA macro for Outlook designed to monitor incoming emails for a specific trigger word," S2 Grupo's LAB52 threat intelligence team said . "When such an email is detected, it enables an attacker to exfiltrate data, upload files, and execute commands on the victim's computer." The artifact gets its name from the use of the word "Nothing" within the source code, the Spanish cybersecurity company added. The activity highlights the abuse of Outlook as a stealthy communication, data exfiltration, and malware delivery channel. The exact initial access vector used to deliver the malware is currently not known, but analysis shows that it's deployed via Microsoft's OneDrive executable ("onedrive.exe") using a t...

Malware or computer virus can infect your computer in several different ways, but one of the most common methods of its delivery is through malicious file attachments over emails that execute the malware when you open them. Therefore, to protect its users from malicious scripts and executable, Microsoft is planning to blacklist 38 additional file extensions by adding them to its list of file extensions that are blocked from being downloaded as attachments in Outlook on the Web. Previously known as Outlook Web Application or OWA, "Outlook on the Web" is Microsoft's web-based email client for users to access their emails, calendars, tasks and contacts from Microsoft's on-premises Exchange Server and cloud-based Exchange Online. The list of blocked file extensions currently has 104 entries, including .exe, .url, .com, .cmd, .asp, .lnk, .js, .jar, .tmp, .app, .isp, .hlp, .pif, .msi, .msh, and more. Now, the expanded block list will also include 38 new extensions...

The campaign is said to have been active only during the Amazon Web Services (AWS) outage in late October 2025. It's assessed ...

What do a source code editor, a smart billboard, and a web server have in common? They've all become launchpads for attacks—because cybercriminals are rethinking what counts as "infrastructure." Instead of chasing high-value targets directly, threat actors are now quietly taking over the overlooked: outdated software, unpatched IoT devices, and open-source packages. It's not just clever—it's reshaping how intrusion, persistence, and evasion happen at scale. ⚡ Threat of the Week 5Socks Proxy Using IoT, EoL Systems Dismantled in Law Enforcement Operation — A joint law enforcement operation undertaken by Dutch and U.S. authorities dismantled a criminal proxy network, known as anyproxy[.]net and 5socks[.]net, that was powered by thousands of infected Internet of Things (IoT) and end-of-life (EoL) devices, enlisting them into a botnet for providing anonymity to malicious actors. The illicit platform, active since 2004, advertised more than 7,000 online proxies daily, with infected ...

New variants of a banking malware called Grandoreiro have been found to adopt new tactics in an effort to bypass anti-fraud measures, indicating that the malicious software is continuing to be actively developed despite law enforcement efforts to crack down on the operation. "Only part of this gang was arrested: the remaining operators behind Grandoreiro continue attacking users all over the world, further developing new malware and establishing new infrastructure," Kaspersky said in an analysis published Tuesday. Some of the other freshly incorporated tricks include the use of a domain generation algorithm (DGA) for command-and-control (C2) communications, ciphertext stealing ( CTS ) encryption, and mouse tracking. Also observed are "lighter, local versions" that are specifically focused on targeting banking customers in Mexico. Grandoreiro , active since 2016, has consistently evolved over time, taking efforts to stay undetected, while also widening its geog...
