Group-IB is the first to uncover a real-world bank heist where threat actor #UNC2891 used a 4G-enabled Raspberry Pi to create physical access to breach the bank’s ATM infrastructure, evading defenses with stealth #Linux backdoors. #ThreatIntel

Cybercrime tactics evolve fast. Which threat concerns you the most right now?

Since 2021, North Korean (#DPRK) IT workers have built a sprawling ecosystem of synthetic developer personas complete with AI‑generated photos, overlapping #GitHub repositories, and reusable portfolio sites. Our investigation uncovered a single GitHub account (cybersage14) that switched identities from “Nicolas Sammaritano” (Argentina) to “Caddo Smith” (Texas) while keeping the same technical profile. This is not isolated fraud; it is a structured, labor‑enabled access model designed to infiltrate global companies and evade sanctions. #InsiderThreat

Fake shipment tracking #scams are rapidly scaling across the #MEA region, exploiting the 161B annual parcel volume that fuels global e-commerce. Attackers use Sender ID spoofing to insert #phishing messages directly into legitimate courier SMS threads, claiming failed deliveries. Victims who click to "update address details" or "pay small fees" are led to pages stealing both credentials and payment data in a two-stage theft process. #ThreatIntel

Threat actors behind #GTFire are systematically abusing Google's trusted infrastructure to evade detection at scale. By chaining Google Firebase hosting with Google Translate's proxy, they create a multi-stage redirect chain that obfuscates final phishing destinations. The https://t.co/Zm9pmjA6xk layer acts as a "phishing shield," leveraging Google's reputation to bypass email security filters and web gateways, with the malicious *.web.app domain only visible deep in the network traffic. #Phishing #ThreatIntel

🚨 Tracking the Rise of Chinese Tap-to-Pay Android Malware

Tap-to-pay fraud is no longer limited to stolen cards or physical proximity. Threat actors are now abusing NFC-enabled #Androidmalware to relay #paymentdata in real time, enabling remote, contactless fraud at scale. Our latest research uncovers how Chinese #cybercrime communities are industrializing this technique and turning it into a fully operational fraud ecosystem.

Key Highlights:
🔹 Over 54 NFC-enabled Android malware samples identified, designed to relay payment APDUs remotely
🔹 Multiple Telegram-based vendors offering tap-to-pay malware as a service, complete with subscriptions, support, and custom regional builds
🔹 At least $355,000 in fraudulent transactions linked to a single illicit POS vendor between Nov 2024 and Aug 2025
🔹 #Smishing and #vishing campaigns actively used to trick victims into installing malware and tapping their cards
🔹 Mule networks and compromised mobile wallets enabling global, card-present fraud without physical cards

Alongside these findings, the research provides in-depth technical analysis of TX-NFC, #NFU, and related variants, examining code overlaps, cash-out infrastructure, and key defensive considerations for #financialinstitutions and payment networks. Read the full research now: https://t.co/4C0ROKNdH8

🚨Bloody Wolf Expands Across Central Asia 🚨

Since June 2025, Group-IB analysts have been tracking a rapidly evolving campaign by #BloodyWolf, an #APTGroup weaponizing trusted government identities to deliver lightweight but highly effective JAR-based loaders.

By impersonating Ministries of Justice and abusing legitimate remote-access software like #NetSupport Manager, the group has quietly scaled its operations from Kyrgyzstan to Uzbekistan supported by geo-fenced infrastructure, tailored lures, and a custom JAR generator designed for stealth and persistence.

Our latest technical blog provides a deep dive into:
🔹 Their #spearphishing techniques and localized PDF lures
🔹 How custom JAR loaders deploy NetSupport RAT
🔹 Infrastructure masquerading as #government portals
🔹 Multi-layered persistence and evasion methods
🔹 IOCs, MITRE mapping, and defensive recommendations

Bloody Wolf shows how low-cost tools and precise #SocialEngineering can evolve into regionally impactful cyber operations.

A coordinated scam campaign is spreading across several regions, including Latin America, using fake news pages and #deepfakes to promote alleged investment platforms.
Goal? to steal personal and payment data by exploiting politically sensitive periods, such as pre- and post-election moments. #ScamAlert

Adversaries can bind-mount a manipulated workspace over /proc/<pid> to rewrite what tools like ps/top show, renaming #malicious processes into benign tokens and sabotaging initial triage. We reproduce this technique end-to-end in our lab walkthrough. #CyberSecurity

[GroupIB_DFIR @GroupIB_DFIR]

Attackers are abusing /proc to spoof process names and start times, making ps & top lie. Our latest investigation shows the technique end to end, with detection and mitigations. Read more: https://t.co/biPsLL2Zhm

🎯 Cybercriminals don’t need to hack your system. They just need to hack your trust.

From fake job offers to “verified account” messages, social media has become a playground for scammers who prey on emotion, urgency, and curiosity.

Understanding how these tactics work is the first step in stopping them.
Our latest carousel breaks down the most common social media scams and how to stay ahead of them.

Think before you click. Verify before you trust.

Group-IB provided critical investigative intelligence supporting @INTERPOL_HQ’s #OperationContender 3.0, a successful multinational cybercrime takedown across Africa. The operation resulted in law enforcement agencies across 14 countries arresting 260 suspects and the seizure of 1,235 electronic devices linked to 81 cybercriminal infrastructures.

These networks, involved in #RomanceScams and #sextortionschemes, caused nearly US$2.8 million in financial losses affecting 1,463 identified victims. Our collaboration with international law enforcement underscores a shared commitment to dismantling criminal operations that cause both financial devastation and profound psychological harm.

This operation highlights the critical importance of public-private partnerships in the ongoing fight against cybercrime.

Between July 24 and August 7, 2025, we observed a 241% surge in #Hacktivist attacks, with 139 incidents linked to 19 distinct groups (11 pro-Cambodian, 8 pro-Thai). The conflict saw a clear division in targeting: Cambodian groups focused on Thai government, education, and healthcare sectors, while Thai groups retaliated against Cambodian government, banking, and education systems. #DDoS attacks constituted the vast majority (103 out of 139) of the offensive operations.

Our report provides unique actor profiles, details their TTPs, and offers actionable defense strategies against DDoS, website defacement, and data leak campaigns. Understand the cyber front of modern #Geopolitical conflict.

From live #deepfakes to scam call centers powered by synthetic voices, #AI is no longer hype—it’s already embedded in cybercrime workflows. According to a report by Resemble AI, in just Q2 2025, deepfake fraud alone caused $350M in damages. Threat actors are scaling impersonation, #phishing, and fraud with AI as a force multiplier.

Group-IB is proud to have supported @INTERPOL_HQ's #OperationSerengeti 2.0, a large-scale multinational crackdown on cybercrime conducted between June and August 2025. Investigators from 18 #African countries and the #UnitedKingdom took part in the operation, which led to the arrest of 1,209 cybercriminals who targeted nearly 88,000 victims worldwide. The coordinated efforts also resulted in US $97.4 million being recovered and 11,432 malicious infrastructure and networks dismantled that were used to facilitate #ransomwareattacks, online scams, and business email compromise (BEC).
