Google and industry partners have dismantled the XCPE malware botnet consisting of more than 1.3 million Android TV streaming TV boxes that Google says its manufacturer intentionally infected with malware to generate revenue through cybercrime activities. [...]

Introduction Last week, Google and industry partners dismantled the XCPE backdoor which enrolled more than 1.3 million set-top boxes into a botnet. We assess with high confidence that the backdoor and botnet were intentionally developed, deployed, and operated for financial gain by Videostrong Technology Co., an Android Original Equipment Manufacturer (OEM) and Original Device Manufacturer (ODM). Videostrong monetized the backdoor by selling access to criminal affiliates and loading those…

V dnešním díle našich Postřehů z bezpečnosti, které vyšly na Root.cz, se podíváme na podvodně získané certifikáty google.as, google.com.gh, youtube.sl a další, koukneme se na zranitelnosti v Dell CSM s upozorníme na firefoxové kapsáře pasoucí po našich peněženkách.
According to Google, attackers compromised infrastructure behind three country-code domain namespaces—.gh (Ghana), .sl (Sierra Leone), and .as (American Samoa)—and used it to obtain unauthorized HTTPS certificates for Google domains and other organizations. These domain endings aren’t limited to sites serving those countries, so the risk can extend to users elsewhere. This wasn’t a break in encryption, and Google’s systems weren’t compromised. Instead, attackers manipulated the internet’s…

Most of us click on search results without knowing much about the website we’re about to visit. And once we’re there, it’s not always obvious when something isn’t quite right. Now, we’ve added two new features to Malwarebytes Browser Guard that will do even more to keep you safe online. Search Reputation gives you a quick read on your search results, before you even click on anything. And with Scam Guard Lite, you can analyze the contents of a webpage directly from the Browser Guard extension…
CERT Polska uncovered a toll fraud operation targeting Polish users through deceptive Meta advertisements and malicious applications distributed via Google Play. We preserved 1235 ads, linked 852 to 17 applications through code or infrastructure, reconstructed the complete execution chain, and observed live premium SMS and carrier billing tasking.
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…
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…
Cisco Talos began an investigation after observing a DLL named "verification.google" executing from WebDAV at a Ukrainian government organization. We assess with moderate confidence that the attacks are not targeted at a particular organization, but are a part of a cryptocurrency and credentials-stealing operation using the Amatera stealer as the primary payload. Pivoting around the similar WebDAV behavior led to a second loader named "pf.ch" and allowed us to reconstruct its earlier delivery…
Cisco Talos is tracking a cryptocurrency-stealing campaign that abuses the Google Visualization API for command and control (C2), retrieving obfuscated JavaScript from a publicly published Google Sheets document and injecting it into the victim's browser session. The actors use a variation on ClickFix social engineering. Instead of convincing targets to run commands against the operating system, they convince targets to paste JavaScript into the Chrome address bar or install it into the…
Scammers are becoming more strategic about where they target people. Nine in ten toll scams—the fake unpaid-toll messages that threaten fines or license suspension—arrive by email or text, while roughly six in ten romance scams show up first on social media. That’s no coincidence. Rather than blasting the same message everywhere, criminals are tailoring different scams to the platforms where they’re most likely to succeed. This finding comes from Malwarebytes’ own threat research systems and…

Researchers have uncovered ToxicPanda 2.0, an Android banking Trojan and remote-access tool designed for account takeover and “on-device fraud.” Not only does ToxicPanda 2.0 have a much larger target list of banks and e-wallets, it has also expanded its capabilities by combining banking overlays, remote access, PIN capture, Android accessibility abuse, and attempted Wireless Debugging automation. Together, those functions can help operators turn a compromised phone into a platform for account…
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…
