Daily Threat Briefing • August 22, 2022

Over 200 infected PyPI and npm packages have been spotted dropping cryptominers after breaking into Linux machines. The packages were observed penetrating Linux systems and installing crypto mining software XMRig. There’s a lot going on in the crypto industry and the enigmatic malware mutations make it even more challenging. Of late, a cybercriminal group has been stealing cryptocurrencies from users of General Bytes, a Bitcoin ATM manufacturer.

A new scam is doing the round wherein cybercriminals are using AWS to generate phishing pages to manipulate victims into blurting out their credentials, all while bypassing the security systems in place.

Top Malware Reported in the Last 24 Hours

PyPI and NPM packages wreck havoc

Researchers reported 241 malicious packages making their way into Python and npm repositories. A majority of these packages typosquat top libraries, thereby duping developers into downloading those. Every malicious package downloads a Bash script on Linux systems that run cryptominers. Some of the open-source libraries and commands that the hackers imitated include React, argparse, and AIOHTTP.

Raccoon and NetSupport RAT on WordPress

Sucuri experts unearthed JavaScript injections targeting WordPress sites by displaying fake DDoS Protection pages to users. Upon clicking on a button, users are redirected to install “security_install.iso’ file that leads victims to download the NetSupport RAT and Raccoon Stealer info-stealing trojan. The latter can not only steal your credentials but also compromise crypto wallets.

Escanor: New malware for PC and Android systems

Resecurity, a cybersecurity firm, discovered a new RAT, dubbed Escanor, being advertised on the dark web and Telegram messenger. The malware is currently available for PCs and Android-based systems. It features an HVNC module and an exploit builder to weaponize MS Office and Adobe PDF documents to deliver malicious code.

A ChromeOS issue needs patching

Microsoft shared technical details on a high-severity ChromeOS bug tracked as CVE-2022-2587 and described as an out-of-bounds write. The issue resides in the CRAS component and could be triggered using malformed metadata associated with songs. It could be exploited for causing DoS conditions and, in limited cases, for attempting an RCE attack.

Zero-day in BTC ATM systems

Hackers exploited a previously undisclosed flaw in the systems of Bitcoin ATM manufacturer General Bytes to steal cryptocurrency from users. The zero-day flaw in the Crypto Application Server (CAS) admin interface was exploited to create an admin user remotely. However, it's unclear how many servers were infiltrated and how much cryptocurrency was stolen by scammers.

Top Scams Reported in the Last 24 Hours

AWS-based phishing campaign

A new phishing campaign, hosted through AWS domains, is sending unsuspecting users a standard password expiration email and other emails to create a sense of urgency. The scam would take responding users to their company’s fake page, auto-populated with their email IDs. If users happen to proceed with entering their passwords, it would reach the cybercriminal’s server.

Agenda’s playbook just got upgraded. The ransomware group has added two new tools: SmokeLoader and a stealthy .NET-based loader called NETXLOADER. The latter leverages techniques like JIT hooking and AES decryption to deploy ransomware and loaders directly into memory, while SmokeLoader injects payloads into explorer.exe using anti-analysis tricks. In a different vein, a bogus debugging package was found duping Discord bot developers. The malicious PyPI package ‘discordpydebug,’ posing as a helpful tool, is designed to steal data and execute commands. Downloaded over 11,500 times, it exploited community trust, mirrored by over 45 npm lookalikes in what appears to be a broader campaign. AWS patched a critical bug in Amplify Studio version 2.20.3. CVE-2025-4318 allowed attackers to inject JavaScript into UI components during render time via the amplify-codegen-ui package. No active exploitation was detected.

In the shadows of the cybersecurity landscape, MintsLoader emerges as a formidable adversary, orchestrating a multi-faceted infection strategy that deploys the notorious GhostWeaver RAT. This malware loader ingeniously employs a blend of obfuscated JavaScript and PowerShell scripts to execute its malicious agenda, utilizing sophisticated evasion techniques and a DGA for C2 communications. Two new malware families—TerraStealerV2 and TerraLogger—are now linked to the Golden Chickens threat group. TerraStealerV2 steals credentials and crypto wallet data but can’t yet bypass Chrome’s built-in encryption, suggesting it’s still in progress. TerraLogger, meanwhile, operates as a standalone keylogger with no exfiltration module, hinting at a plug-and-play role in a broader MaaS toolkit. A fake refund for a real blackout. A phishing campaign is spoofing TAP Air Portugal, preying on confusion after the Iberian power outage. Victims are promised compensation for delayed flights, only to be directed to phishing pages that steal payment details.

Some PyPI packages are doing more than importing functions. Researchers uncovered seven malicious Python packages under the “Coffin” naming scheme, using Gmail’s SMTP service as a stealthy C2 channel. Hardcoded credentials let the malware establish outbound tunnels via port 465, send activation signals, and quietly exfiltrate data. Apache ActiveMQ users should be on high alert. A flaw in its .NET Message Service library now lets remote attackers inject code by abusing deserialization. All versions prior to the latest update are at risk, so prompt patching is essential to protect your systems. Emails that look like official Social Security alerts are turning into dangerous gateways. In the new Molatori phishing campaign, attackers send messages claiming your Social Security Statement is ready to download.

Ransomware groups aren’t always the ones breaking the door open. Researchers have uncovered ToyMaker, an initial access broker selling network entry to ransomware groups. Using a custom malware strain called LAGTOY, ToyMaker establishes reverse shells and executes commands on compromised systems. After gaining access, ToyMaker hands over the keys - leaving ransomware operators to finish the job. Industrial remote access just got a lot more dangerous. Three vulnerabilities have been discovered in the IXON VPN client, affecting both Windows and Linux. Attackers can exploit temporary file handling flaws to escalate privileges.

An APT group with deep roots in Southeast Asia is quietly siphoning data through everyday cloud platforms. Earth Kurma has been active since late 2020, targeting government and telecom entities across the Philippines, Vietnam, Thailand, and Malaysia. Its extensive toolkit enables credential theft, stealthy surveillance, and Dropbox-based exfiltration. One patch, two problems. Microsoft’s fix for CVE-2025–21204 may have closed a privilege escalation bug but it opened the door to a DoS vulnerability. By creating junction points, non-admin users can block future Windows updates from installing. There’s no fix yet, and unless the rogue junction is manually removed, security updates will fail silently. Logos, lures, and lies - the Power Parasites campaign is using all three. Fraudsters are impersonating global energy brands to scam victims in Bangladesh, Nepal, and India through fake jobs and investment offers. With over 150 domains and active Telegram and YouTube promotion, the scheme blends fake onboarding forms with identity theft and financial fraud, all under the guise of renewable energy.
