Cybercriminals are increasingly leveraging residential proxy services to mask malicious web traffic, making it appear as routine online activity and evading detection. This tactic involves routing illicit activities through a network of real IP addresses assigned to homes and offices, making it difficult to distinguish between legitimate and harmful traffic. Researchers at the Sleuthcon conference in Arlington, Virginia, highlighted this growing trend, noting that the shift towards using proxies has become significant in recent years as law enforcement agencies have become more effective at targeting traditional "bulletproof" hosting services.
The core issue lies in the fact that proxy services are designed to obfuscate the source of web traffic, making it nearly impossible to identify malicious actors within a node. As Thibault Seret, a researcher at Team Cymru, explained, the strength of a proxy service lies in its anonymity, which while beneficial for internet freedom, presents a major challenge for analyzing and identifying harmful activities. This is particularly true of residential proxies, which use real IP addresses of everyday internet users, blurring the lines between legitimate and criminal behavior. The use of residential proxies by cybercriminals represents a significant shift in tactics, prompting security professionals to reassess their detection strategies. These proxies operate on consumer devices like old Android phones or low-end laptops, making it even more difficult to trace the origin of malicious activities. As criminals and companies seek to maintain anonymity and privacy, they are increasingly relying on these services, complicating the efforts to combat cybercrime effectively. Recommended read:

A concerning trend of hackers exploiting open-source software supply chains has been identified, with malicious backdoors being planted in Python and NPM packages. Security researchers at Checkmarx Zero have uncovered a sophisticated campaign where attackers are using typosquatting and name-confusion tactics to trick users into downloading harmful software. This cross-ecosystem approach targets both Windows and Linux systems, deploying multi-platform payloads with the capability to steal data and establish remote control. These findings highlight the growing need for enhanced security measures within open-source ecosystems to combat supply chain attacks.
This campaign leverages the Python Package Index (PyPI) and Node Package Manager (NPM) by mimicking legitimate software. Specifically, the attack targeted users of "colorama," a popular Python tool, and "colorizr," a similar JavaScript package, by uploading packages with names like "coloramapkgs" and "colorizator". The malicious packages carry dangerous payloads designed to give attackers remote access and control, allowing them to harvest and exfiltrate sensitive data. On Windows systems, the malware attempts to bypass antivirus software, while on Linux, it establishes encrypted connections, steals information, and maintains a hidden presence. Fortunately, the identified malicious packages have been removed from public software repositories, limiting their immediate potential for damage. However, the lack of clear attribution data makes it difficult to trace the campaign back to a known adversary. Vet, an open-source tool designed to help developers and security engineers spot risks in their software supply chains, goes beyond traditional software composition analysis by detecting known vulnerabilities and flagging malicious packages. It supports ecosystems like npm, PyPI, Maven, Go, Docker, and GitHub Actions, assisting in the detection of supply chain attacks. Recommended read:

Critical vulnerabilities have been disclosed in several software products, raising concerns about potential security breaches. Two significant flaws have been identified in vBulletin forum software, tracked as CVE-2025-48827 and CVE-2025-48828. These vulnerabilities, with CVSS v3 scores of 10.0 and 9.0 respectively, enable API abuse and remote code execution. One of the flaws is reportedly being actively exploited in the wild, posing an immediate threat to vBulletin users. The vulnerabilities affect vBulletin versions 5.0.0 through 5.7.5 and 6.0.0 through 6.0.3 when running on PHP 8.1 or later, however the vulnerabilities were likely patched last year in Patch Level 1 of the 6.* release branch.
Exploit details for a serious vulnerability in Cisco IOS XE Wireless Controller, designated CVE-2025-20188, have been publicly released, increasing the risk of exploitation. This vulnerability allows an attacker to take over devices by uploading files, performing path manipulation, and executing arbitrary commands with root privileges. The issue stems from a hardcoded JSON Web Token (JWT) which allows unauthenticated, remote attackers to generate valid tokens without knowing any secret information. Cisco has advised affected users to take immediate action to secure their systems. Horizon3's analysis shows the Cisco IOS XE WLC vulnerability is caused by a hardcoded JWT fallback secret ('notfound'). If the file ‘/tmp/nginx_jwt_key’ is missing, the script uses ‘notfound’ as the secret key to verify JWTs, allowing attackers to generate valid tokens without knowing any secret information. They can then send an HTTP POST request with a file upload to the ‘/ap_spec_rec/upload/’ endpoint via port 8443 using path manipulation in the file name to place an innocent file (foo.txt) outside the intended directory. To escalate the file upload vulnerability to remote code execution, an attacker can overwrite configuration files loaded by backend services, place web shells, or abuse monitored files to perform unauthorized actions. Users are advised to upgrade to a patched version (17.12.04 or newer) as soon as possible. Recommended read:

An international law enforcement operation, dubbed Operation Endgame, has successfully taken down AVCheck, a notorious service used by cybercriminals to test their malware against antivirus software. The coordinated effort involved law enforcement agencies from multiple countries, including the US, Netherlands, and Finland. This takedown represents a significant blow to cybercriminal infrastructure, as AVCheck was one of the largest counter antivirus (CAV) services operating globally, enabling criminals to refine their malware to evade detection by security software. The service allowed users to upload their malware and test it against various antivirus engines, ensuring it could slip past defenses undetected.
The takedown included the seizure of the AVCheck domain (avcheck.net) along with several other related domains, including Cryptor.biz, Cryptor.live, Crypt.guru, and Getcrypt.shop, which provided "malware crypting" services. These crypting services were closely linked to AVCheck's administrators and helped malware authors obfuscate their code, further enhancing its ability to bypass antivirus detection. Authorities made undercover purchases from seized websites and analyzed the services, confirming they were designed for cybercrime. Court documents also allege authorities reviewed linked email addresses and other data connecting the services to known ransomware groups that have targeted victims both in the United States and abroad. The Dutch police played a crucial role in the operation, even setting up a fake login page on AVCheck prior to the takedown. This fake page warned users about the legal risks associated with using the service and collected data on those attempting to log in. This tactic allowed law enforcement to gather valuable intelligence on the users of AVCheck and potentially deter them from engaging in further cybercriminal activities. Authorities have highlighted the importance of international cooperation in combating cybercrime, emphasizing the need to target not just individual cybercriminals but also the services and infrastructure that enable their malicious activities.

A new multi-platform malware campaign is targeting organizations in Southern Europe, specifically Spain, Italy, and Portugal, through sophisticated phishing emails. This campaign leverages weaponized PDF invoices to deliver a Java-based Remote Access Trojan (RAT) known as RATty. The attack begins with emails that bypass SPF/DKIM checks by abusing Spain's serviciodecorreo.es email service, allowing forged sender addresses to appear legitimate. The emails contain a PDF attachment mimicking an invoice from Medinova Health Group, enticing recipients to click a Dropbox link.
This link redirects victims to an HTML file (Fattura.html) that initiates a multi-stage verification process, including a fake CAPTCHA, to further deceive the user. The HTML file then utilizes Ngrok tunneling to dynamically switch content based on the victim's geolocation. If the request originates from Italy, the user is redirected to MediaFire to download a malicious Java Archive (JAR) file named FA-43-03-2025.jar. Users outside of Italy are redirected to benign Google Drive documents, effectively bypassing automated sandboxes typically hosted in cloud regions outside Italy. The final JAR file contains the RATty malware, a cross-platform Remote Access Trojan that exploits Java's capabilities to grant attackers extensive control over the compromised system. This includes remote command execution, keystroke logging, screenshot capture, and data exfiltration. The attackers may also repackage RATty in MSI installers, further disguising the threat as a software update to increase the odds of user execution. Organizations are advised to update endpoint protection tools to defend against this evolving phishing tactic. Recommended read:

Ransomware attacks have surged in 2025, evolving into more sophisticated and dangerous threats than ever before. What started as simple file encryption schemes has morphed into full-blown extortion ecosystems. These modern attacks now involve data exfiltration, public shaming of victims, and even DDoS attacks, marking a significant escalation in cybercriminal tactics. According to Check Point Research, the first quarter of 2025 saw a record-breaking 2,289 victims published on data leak sites, representing a staggering 126% year-over-year increase, demonstrating the growing threat volume and the evolving tactics employed by attackers.
The rise of Ransomware-as-a-Service (RaaS) has also significantly contributed to the increased threat landscape. Check Point's 2024 Annual Ransomware Report revealed that 46 new ransomware groups emerged in that year alone, a 48% increase compared to the previous year. These groups offer ready-made ransomware kits, lowering the barrier to entry for cybercriminals and enabling a wider range of actors to launch attacks. Experts are particularly concerned about the potential for "triple extortion" models, which combine DDoS attacks, public leak threats, and direct harassment of customers or partners to pressure victims into paying ransoms. In addition to the increasing sophistication of ransomware itself, cybercriminals are also abusing legitimate tools to blend in with compromised environments. The Cactus ransomware gang, for example, has been known to direct victims to initiate Microsoft Quick Assist remote access sessions, even assisting them with the installation of the program. With Anti-Ransomware Day being on May 12, organizations are urged to prioritize proactive defenses, incident response planning, and employee awareness training to mitigate the growing risk of ransomware attacks in 2025 and beyond.

These platforms masquerade as legitimate AI services for creating videos, logos, images, and even websites, attracting users eager to leverage AI for content creation.
Posts promoting these fake AI tools have garnered significant attention, with some reaching over 62,000 views. Users who click on the advertised links are directed to bogus websites, such as one impersonating CapCut AI, where they are prompted to upload images or videos. Instead of receiving the promised AI-generated content, users are tricked into downloading a malicious ZIP archive named "VideoDreamAI.zip," which contains an executable file designed to initiate the infection chain. The "Video Dream MachineAI.mp4.exe" file within the archive launches a legitimate binary associated with ByteDance's CapCut video editor, which is then used to execute a .NET-based loader. This loader, in turn, retrieves a Python payload from a remote server, ultimately leading to the deployment of the Noodlophile Stealer. This malware is capable of harvesting browser credentials, cryptocurrency wallet information, and other sensitive data. In some instances, the stealer is bundled with a remote access trojan like XWorm, enabling attackers to gain entrenched access to infected systems. Recommended read:

Recorded Future's Insikt Group has released a report detailing the discovery of two new malware families, TerraStealerV2 and TerraLogger, both linked to the notorious Golden Chickens threat actor, also known as Venom Spider. Golden Chickens is a financially motivated group known for providing a Malware-as-a-Service (MaaS) platform, offering cybercriminals a suite of malicious tools. The newly identified malware strains add to their existing arsenal, which includes tools like VenomLNK, TerraLoader, and TerraCrypt, which have been implicated in past attacks against major organizations. The report, published on May 1, 2025, highlights the evolving tactics of this sophisticated threat actor.
TerraStealerV2 is designed to steal browser credentials, target cryptocurrency wallets, and pilfer browser extensions. This stealer malware is delivered through various file types, including LNK, MSI, DLL, and EXE files, and utilizes legitimate Windows tools like regsvr32.exe and mshta.exe to bypass endpoint detection. While TerraStealerV2 lacks the ability to decrypt credentials protected by Chrome’s Application Bound Encryption (ABE), a security measure introduced in mid-2024, it can still exfiltrate unprotected data. It copies cryptocurrency wallet directories and uploads them to Telegram bots and wetransfers[.]io, a lookalike domain hosted behind Cloudflare, showcasing the malware's data theft capabilities. TerraLogger represents the first keylogging capability developed by Golden Chickens. This standalone keylogger records keystrokes locally using a low-level keyboard hook and stores them in plaintext files within the C:\ProgramData directory. While TerraLogger currently lacks command-and-control or data exfiltration logic, its modular design suggests it is either under development or intended to be used in conjunction with other components of the Golden Chickens toolkit. Experts suggest the group continues to refine its delivery methods by combining VenomLNK attacks with Windows-native tools, indicating a persistent effort to evolve and enhance their malicious operations.

A recent supply chain attack has targeted Magento e-commerce stores, compromising hundreds of online businesses. Sansec researchers uncovered that 21 Magento extensions had been backdoored, leading to the compromise of an estimated 500 to 1,000 e-commerce stores, including a major multinational corporation valued at $40 billion. The attackers gained access to the servers of three Magento software developers – Magesolution, Meetanshi, and Tigren – and modified the source code of the extensions.
The malicious code, a backdoor hidden in the License.php file, remained dormant for six years. The attackers exploited the backdoor in April 2025, deploying malicious code onto Magento stores that had installed the compromised plugins. This backdoor allowed the key holder to run commands on the server, granting them full control of the e-commerce servers and enabling them to steal sensitive information. While removing the compromised extensions will eliminate the initial entry point, experts recommend a thorough check of affected stores to ensure the attackers didn't leave additional web shells for secondary access. Sansec has notified the plugin developers of the breach, but responses have varied, ranging from denial to confirmation of a server hack. Users of Magento e-commerce platforms are urged to investigate their installed extensions and implement security measures to mitigate the risks associated with supply chain attacks. Recommended read:

Cybercriminals are increasingly leveraging adversary-in-the-middle (AiTM) attacks with reverse proxies to bypass multi-factor authentication (MFA), a security measure widely adopted to protect against unauthorized access. This sophisticated technique allows attackers to intercept user credentials and authentication cookies, effectively neutralizing the added security that MFA is designed to provide. Instead of relying on simple, fake landing pages, attackers position reverse proxies between the victim and legitimate web services, creating an authentic-looking login experience. This method has proven highly effective in capturing sensitive information, as the only telltale sign might be a subtle discrepancy in the browser's address bar.
The proliferation of Phishing-as-a-Service (PhaaS) toolkits has significantly lowered the barrier to entry for executing these complex attacks. Platforms like Tycoon 2FA and Evilproxy offer ready-made templates for targeting popular services and include features like IP filtering and JavaScript injection to evade detection. Open-source tools such as Evilginx, originally intended for penetration testing, have also been repurposed by malicious actors, further exacerbating the problem. These tools provide customizable reverse proxy capabilities that enable even novice cybercriminals to launch sophisticated MFA bypass campaigns. To combat these evolving threats, security experts recommend that organizations reassess their current MFA strategies and consider adopting more robust authentication methods. WebAuthn, a passwordless authentication standard utilizing public key cryptography, offers a potential solution by eliminating password transmission and rendering server-side authentication databases useless to attackers. Additionally, organizations should implement measures to detect unusual session behavior, monitor for newly registered domains, and analyze TLS fingerprints to identify potential AiTM activity. By staying vigilant and adapting their security strategies, organizations can better defend against these advanced phishing techniques and protect their valuable assets. Recommended read:

Following a series of cyberattacks targeting major UK retailers including Marks & Spencer, Co-op, and Harrods, the National Cyber Security Centre (NCSC) has issued an urgent alert, urging organizations to bolster their defenses. The attacks, which involved ransomware and data theft, have caused significant operational disruptions and data breaches, highlighting the increasing risk faced by the retail sector. The NCSC anticipates that similar attacks are likely to escalate and emphasizes that preparation is key to ensuring business continuity and minimizing financial losses.
The NCSC advises businesses to take immediate and proactive measures to mitigate risks. A key recommendation is to isolate and contain threats quickly by severing internet connectivity immediately to prevent malware from spreading further across networks. It's equally important to ensure that backup servers remain isolated and unaffected by the attack, so they can be used for disaster recovery. The security agency is also calling on firms to review their password reset policies, and in particular how IT help desks authenticate workers when they make a reset request, especially in the case of senior employees with escalated privileges. To enhance cyber resilience, the NCSC stresses the importance of implementing multi-factor authentication (MFA) across the board. The agency also warns organizations to be constantly on the lookout for ‘risky logins’ within Microsoft Entra ID Protection, where sign-in attempts are flagged as potentially compromised due to suspicious activity or unusual behaviour. The Information Commissioner's Office (ICO) has similar advice warning organizations to make sure that accounts are protected by a strong password, and that passwords aren't being reused across multiple accounts. While attacks against UK retailers have rocked the industry in recent weeks, the NCSC's guidance aims to help businesses avoid falling victim to similar incidents. Recommended read:

Google's Threat Intelligence Group (GTIG) has released its annual review of zero-day exploits, revealing a concerning shift towards enterprise-targeted attacks in 2024. The report highlights a persistent rise in zero-day exploitation, with 75 vulnerabilities actively exploited in the wild. While this number represents a decrease from the 98 exploits observed in 2023, it remains higher than the 63 recorded in 2022, indicating a continued upward trend. The GTIG's analysis divides these vulnerabilities into two main categories: end-user platforms and products, and enterprise-focused technologies such as security software and appliances.
Of the 75 zero-day exploits tracked in 2024, a significant 44% targeted enterprise products. This indicates a strategic shift from attackers who are increasingly recognizing the value in compromising systems that house sensitive data. In contrast, the exploitation of browsers and mobile devices has decreased, falling by about a third and half, respectively. This shift towards enterprise technologies suggests that attackers are focusing on more lucrative targets that offer greater potential rewards. The GTIG report also notes that exploit chains made up of multiple zero-day vulnerabilities continue to be almost exclusively used to target mobile devices. Government-backed hackers and commercial surveillance vendors (CSVs) are the primary actors behind many of these exploits. The GTIG report indicates that governments like China and North Korea, along with spyware makers, are responsible for the most recorded zero-days in 2024. Specifically, at least 23 zero-day exploits were linked to government-backed hackers, with 10 directly attributed to governments including five linked to China and five to North Korea. Additionally, spyware makers and surveillance enablers were responsible for eight exploits, suggesting that the industry will continue to grow as long as government customers continue to request and pay for these services.
