Researchers at Zimperium’s zLabs have analyzed an Android Trojan that uses an automated, multi-stage infection process. What’s new is that RatHat gives a live AI assistant the keys to the accessibility tree of the infected device and uses it to determine where to tap or scroll, rather than following a hardcoded script. The variable attack path makes it harder for signature- and rule-based mobile security tools to detect this Trojan. It also abuses Android Debug Bridge (ADB), a legitimate tool…
Only days after Revolut acknowledged that it disclosed sensitive customer records to an unauthorized party, affected customers are receiving phishing texts. However, we don’t know yet if the phishing texts are linked to the breach. The company had accepted fraudulent information requests sent from an email address on a legitimate government agency domain. Through this social engineering attack, rather than by gaining access to Revolut’s systems, the criminals obtained the following types of…

Elastic Security Labs has tracked REF9334, a Brazilian banking malware operation, since May 2025. Its toolkit is called KREMLIN (as named by the malware author, Kr3mlin4rt1st), though nothing about the operation is Russian. Lures impersonate twelve Brazilian banks; error messages and code comments are written in Portuguese, and the operators' Ethereum transactions cluster during São Paulo working hours. Over 15 months and seven campaigns, they built a malicious browser extension that installs…
An attacker breached an email marketing platform and launched targeted attacks against the newsletter subscribers of some of its customers, especially those working in cryptocurrency and adjacent fields. The incident was a supply-chain phishing campaign carried out through Brevo, an email marketing provider used by several cryptocurrency companies and other firms. Brevo initially said an attacker had gained access to 120 customer accounts, some of which were used to send phishing emails to the…
Researchers at Group-IB found that the Android banking Trojan Gigabud can create a separate work profile on an infected phone and run a cloned banking app inside it. The attacker can then carry out fraudulent transactions in the new profile, potentially separating them from signs of malware detected elsewhere on the device. To do this, Gigabud installs Vwork, a malicious version of the legitimate open-source tool Shelter. Shelter normally lets Android users isolate apps or run second copies of…

Key Takeaways Since March 31, 2025, all 51 former “best practice” requirements in PCI DSS 4.0 have been fully scored. Every 2026 assessment covers them. A large share of the new weight sits in the PCI DSS 4.0.1 application requirements, concentrated in Requirements 6 and 11: inventory of custom applications and APIs, continuous protection of public-facing apps, payment page script management, authenticated scanning, and risk-based prioritization. 6.4.3 and 11.6.1 now require a complete…
IntroductionDespite modern verification controls, identity theft remains one of the most pervasive threats to both individuals and enterprise organizations. U.S. Federal Trade Commission statistics show over 1 million identity theft reports annually, with related fraud and imposter scams accounting for billions in financial losses each year. While stolen credit cards enable rapid, short-term monetization, Social Security numbers (SSNs) represent a far more permanent and dangerous tier within…

Nový malware s názvem WindRelay v kombinaci s trojanem SpyNote umožňuje zneužít zařízení s Androidem k bezkontaktním platebním podvodům. Útočníci oběť pomocí phishingu, SMS nebo telefonátu přesvědčí k instalaci škodlivé aplikace a následně k přiložení platební karty k telefonu, například pod záminkou ověření identity či změny PINu. Malware zachycenou NFC komunikaci v reálném čase přenáší do zařízení útočníka, který tak může kartu využít k platbám nebo výběrům hotovosti. Mezi listopadem 2025 a…
Researchers at Group-IB have discovered a new NFC relay malware family, purpose-built to capture live card data via NFC and forward it in real time to attackers. They dubbed it “WindRelay.” NFC (Near Field Communication) is wireless technology that allows devices such as smartphones, payment cards, and payment terminals to communicate when they’re very close together. So, instead of stealing your physical bank card, the attackers capture NFC activity on an infected mobile phone and relay it in…
