Daily Threat Briefing • May 16, 2025

Procolored’s software downloads came bundled with more than just printer drivers. Researchers uncovered two embedded threats: SnipVex and XRedRAT. One BTC wallet linked to the malware racked up over $100,000, with infections traced back to nearly 40 compromised executables.

A jailbreak enabler reemerges from the patch notes. An iOS kernel vulnerability fixed last year has resurfaced through a public proof-of-concept exploit. The flaw allows unsigned apps to escalate privileges, potentially fueling future jailbreak chains. Devices running older OS versions remain at risk despite Apple’s tightened certificate validation.

Criminals are now cloning voices with AI and using them to phish officials. The FBI warns of deepfake audio-driven vishing campaigns impersonating senior U.S. figures to access sensitive accounts. These attacks often begin with smishing texts and evolve into sophisticated voice calls, combining stolen credentials and social engineering to extract more valuable data.

Top Malware Reported in the Last 24 Hours

Malware spotted in printer software

An investigation revealed the presence of SnipVex and XRedRAT malware in Procolored's software downloads, including Win32.Backdoor.XRedRAT.A and MSIL.Trojan-Stealer.CoinStealer.H.Malware. The XRed backdoor, identified in the PrintExp.exe sample, has existed since at least 2019 and allows malicious activities like keylogging, file downloads, and executing commands. The SnipVex virus, a clipbanker, diverts cryptocurrency transactions by replacing clipboard BTC addresses and infects executable files. The malware’s impact included 39 infected files and a BTC address linked to the attacker, which received approximately 9.3 BTC (~$100,000).

LNK files drop Remcos RAT

A new malware campaign utilizes a PowerShell-based loader to deploy the Remcos RAT, employing malicious LNK files and mshta.exe for execution. Delivered via malicious LNK files in ZIP archives, the attack utilizes mshta.exe to run obfuscated VBScript, bypassing Windows Defender. The malware modifies the Windows Registry for persistence, downloads multiple payloads, and executes code directly in memory using Win32 APIs. Remcos features modules for keylogging, webcam access, and credential theft from browsers, employing anti-analysis techniques to evade detection. The latest version includes enhanced functionalities for managing victim machines.

Top Vulnerabilities Reported in the Last 24 Hours

Critical iOS kernel vulnerability

A critical iOS kernel vulnerability (CVE-2023-41992), patched by Apple in September 2023, has resurfaced in a public proof of concept. The vulnerability allows malicious apps to bypass signature validation and elevate privileges, affecting iOS, iPadOS, macOS, and watchOS versions before iOS 16.7. Apple acknowledged the flaw may have been actively exploited and addressed it by enhancing certificate validation and kernel-level checks. The vulnerability could enable jailbreak tools like TrollStore or Serotonin and be integrated into future jailbreak chains, especially on older, unpatched devices.

New Intel CPU bugs enable memory leaks

ETH Zurich researchers have discovered a new security vulnerability in Intel processors, named Branch Privilege Injection. This flaw exploits speculative technologies in CPUs, enabling attackers to bypass security barriers and access sensitive data from other users on shared processors. All Intel processors manufactured since 2018 are affected, including those in PCs, laptops, and data center servers. The vulnerability arises from brief race conditions during prediction calculations, allowing hackers to gradually read the entire memory contents byte by byte.

Top Scams Reported in the Last 24 Hours

U.S. officials targeted in vishing campaign

The FBI has issued a warning about cybercriminals using AI-generated audio deepfakes in voice phishing attacks targeting U.S. officials since April. These attackers impersonate senior officials to gain access to personal accounts and sensitive information through techniques like smishing and vishing. By compromising accounts, they can access contact information and employ social engineering to steal further sensitive data and funds.

Swan Vector is the latest addition to a string of APT campaigns zeroing in on East Asia’s research and engineering sectors. Seqrite Labs uncovered the group’s four-stage malware chain, beginning with a malicious LNK in a ZIP archive and culminating in Cobalt Strike deployment. A PowerShell script posing as a helpful utility is the entry point for Chihuahua Stealer. This .NET-based info-stealer uses scheduled tasks for persistence and grabs browser credentials and crypto wallet data. It compresses the loot, encrypts it, and exfiltrates over HTTPS - all while cleaning up traces. Microsoft’s latest Patch Tuesday addresses 78 vulnerabilities, including five zero-days actively exploited in the wild. Among the critical flaws is a CVSS 10 bug in Azure DevOps Server. The CISA has flagged these vulnerabilities as high priority for federal agencies, emphasizing risks around memory corruption and privilege escalation. SAP’s NetWeaver platform is now at the center of a global cyber campaign. Chinese APT groups have been exploiting CVE-2025-31324 to gain remote code execution via unauthenticated file uploads, targeting over 580 systems.

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.
