Amazon has announced that its threat intelligence division has intervened in ongoing cyber operations attributed to hackers associated with Russia’s foreign military intelligence service, the GRU. The activity targeted organizations using Amazon’s cloud infrastructure, with attackers attempting to gain unauthorized access to customer-managed systems.
The company reported that the malicious campaign dates back to 2021 and largely concentrated on Western critical infrastructure. Within this scope, energy-related organizations were among the most frequently targeted sectors, indicating a strategic focus on high-impact industries.
Amazon’s investigation shows that the attackers initially relied on exploiting security weaknesses to break into networks. Over multiple years, they used a combination of newly discovered flaws and already known vulnerabilities in enterprise technologies, including security appliances, collaboration software, and data protection platforms. These weaknesses served as their primary entry points.
As the campaign progressed, the attackers adjusted their approach. By 2025, Amazon observed a reduced reliance on vulnerability exploitation. Instead, the group increasingly targeted customer network edge devices that were incorrectly configured. These included enterprise routers, VPN gateways, network management systems, collaboration tools, and cloud-based project management platforms.
Devices with exposed administrative interfaces or weak security controls became easy targets. By exploiting configuration errors rather than software flaws, the attackers achieved the same long-term goals: maintaining persistent access to critical networks and collecting login credentials for later use.
Amazon noted that this shift reflects a change in operational focus rather than intent. While misconfiguration abuse has been observed since at least 2022, the sustained emphasis on this tactic in 2025 suggests the attackers deliberately scaled back efforts to exploit zero-day and known vulnerabilities. Despite this evolution, their core objectives remained unchanged: credential theft and quiet movement within victim environments using minimal resources and low visibility.
Based on overlapping infrastructure and targeting similarities with previously identified threat groups, Amazon assessed with high confidence that the activity is linked to GRU-associated hackers. The company believes one subgroup, previously identified by external researchers, may be responsible for actions taken after initial compromise as part of a broader, multi-unit campaign.
Although Amazon did not directly observe how data was extracted, forensic evidence suggests passive network monitoring techniques were used. Indicators included delays between initial device compromise and credential usage, as well as unauthorized reuse of legitimate organizational credentials.
The compromised systems were customer-controlled network appliances running on Amazon EC2 instances. Amazon emphasized that no vulnerabilities in AWS services themselves were exploited during these attacks.
Once the activity was detected, Amazon moved to secure affected instances, alerted impacted customers, and shared intelligence with relevant vendors and industry partners. The company stated that coordinated action helped disrupt the attackers’ operations and limit further exposure.
Amazon also released a list of internet addresses linked to the activity but cautioned organizations against blocking them without proper analysis, as they belong to legitimate systems that had been hijacked.
To mitigate similar threats, Amazon recommended immediate steps such as auditing network device configurations, monitoring for credential replay, and closely tracking access to administrative portals. For AWS users, additional measures include isolating management interfaces, tightening security group rules, and enabling monitoring tools like CloudTrail, GuardDuty, and VPC Flow Logs.
A dangerous malware campaign known as BadBox 2.0 has infected more than 10 million Android-powered devices, according to a recent alert from the FBI and major cybersecurity researchers. Users are being advised to immediately disconnect any suspicious smart devices connected to their home networks.
This large-scale cyberattack targets a range of low-cost electronics, such as smart TVs, tablets, digital picture frames, car infotainment systems, and streaming boxes, many of which are manufactured by lesser-known brands and sold at discounted prices. Authorities warn that these products may already be infected before leaving the factory.
How Are Devices Getting Infected?
Investigators say that the malware is often pre-installed into the system’s firmware, meaning it’s embedded into the device itself. In some cases, users unknowingly allow the malware in when accepting software updates or installing apps from unofficial sources.
Once active, the malware can silently take over the infected device, turning it into part of a global botnet. These infected devices are then used by cybercriminals for illegal activities like online ad fraud, credential theft, and hiding internet traffic through proxy networks.
The LAT61 Threat Intelligence Team at Point Wild helped trace how the malware operates. They discovered that the malware secretly converts devices into residential proxy nodes, making it hard to detect while still carrying out harmful actions behind the scenes.
What Are Google and the FBI Doing?
In response to the threat, Google has taken legal action against the individuals behind BadBox 2.0 and has updated its Google Play Protect system to block apps associated with the malware. The FBI, through alert I-060525-PSA, has also issued a detailed warning and urged users to take caution, especially with devices from unverified brands.
The team at Human Security, which first exposed the malware operation, confirmed that multiple hacker groups contributed to building and maintaining the botnet infrastructure. Their CEO praised the collaboration between cybersecurity firms, law enforcement, and tech companies to take down the threat.
A New Threat Also Detected
Meanwhile, researchers from GreyNoise have reported signs of another emerging cyber threat, this time involving VoIP (Voice over Internet Protocol) devices. Their investigation revealed a spike in activity where hackers are attempting to gain access to poorly secured systems using default or weak passwords. These devices are often older, rarely updated, and left exposed to the internet, making them easy targets.
What Should You Do?
The FBI advises users to look out for the following red flags:
1. Devices requiring you to turn off Google Play Protect
2. Gadgets that offer “fully unlocked” or “free streaming” features
3. Unfamiliar or generic brand names
4. Apps from third-party app stores
5. Unexpected internet activity from your devices
If you notice any of these signs, disconnect the device from your network immediately and consider replacing it with a trusted brand.
Cybersecurity experts have identified the healthcare industry as the most frequently targeted sector for third-party breaches in 2024, with 41.2% of such incidents affecting medical institutions. This highlights a critical need for improved security measures across healthcare networks.
The Growing Threat of Unnoticed Cyber Breaches
A recent cybersecurity study warns of the increasing risk posed by “silent breaches.” These attacks remain undetected for extended periods, allowing hackers to infiltrate systems through trusted third-party vendors. Such breaches have had severe consequences in multiple industries, demonstrating the dangers of an interconnected digital infrastructure.
Research from Black Kite’s intelligence team examined cybersecurity incidents from regulatory disclosures and public reports, revealing an alarming rise in sophisticated cyber threats. The findings emphasize the importance of strong third-party risk management to prevent security lapses.
Why Healthcare is at Greater Risk
Several factors contribute to the vulnerability of healthcare institutions. Medical records contain highly valuable personal and financial data, making them prime targets for cybercriminals. Additionally, the healthcare sector relies heavily on external vendors for essential operations, increasing its exposure to supply chain weaknesses. Many institutions also struggle with outdated security infrastructures, further amplifying risks.
Encouragingly, the study found that 62.5% of healthcare vendors improved their security standards following a cyber incident. Regulatory requirements, such as HIPAA compliance, have played a role in compelling organizations to enhance their cybersecurity frameworks.
Major Findings from the Report
The study highlights key security challenges that organizations faced in 2024:
1. Unauthorized Access to Systems: More than half of third-party breaches involved unauthorized access, underscoring the need for stronger access control measures.
2. Ransomware Attacks on the Rise: Ransomware remained a leading method used by cybercriminals, responsible for 66.7% of reported incidents. Attackers frequently exploit vendor-related weaknesses to maximize impact.
3. Software Vulnerabilities as Entry Points: Cybercriminals took advantage of unpatched or misconfigured software, including newly discovered weaknesses, to infiltrate networks.
4. Credential Theft Increasing: About 8% of attacks involved stolen or misused credentials, highlighting the necessity of robust authentication methods, such as multi-factor authentication.
5. Targeting of Software Vendors: A major 25% of breaches were linked to software providers, reflecting an increased focus on exploiting weaknesses in the software supply chain.
With organizations becoming increasingly reliant on digital tools and cloud-based systems, cyber risks continue to escalate. A single vulnerability in a widely used platform can trigger large-scale security incidents.
To mitigate risks, businesses must adopt proactive strategies, such as continuous monitoring, prompt software updates, and stricter access controls. Strengthening third-party security practices is essential to minimizing the likelihood of breaches and ensuring the safety of sensitive data.
The healthcare sector, given its heightened exposure, must prioritize comprehensive security measures to reduce the impact of future breaches.
A recent report by Group-IB has exposed a highly advanced phishing campaign targeting employees from 30 companies across 15 jurisdictions. Using trusted domains and cutting-edge personalization techniques, attackers have bypassed Secure Email Gateways (SEGs) and exploited victims in critical sectors such as finance, government, aerospace, and energy.
The investigation, initiated in July 2024, uncovered the attackers' use of:
“Nine out of ten cyberattacks start with a phishing email, making it the most common entry point for threat actors,” the report emphasized.
The attackers used professionally designed phishing emails that impersonated well-known brands, including:
These emails featured professional formatting, familiar logos, and dynamically personalized elements. For example, by extracting a victim’s email domain, the attackers matched logos and page titles to the targeted organization, enhancing credibility.
“Scammers use a technique that dynamically pulls company logos from the official website to make the phishing links look legitimate,” the report noted.
The attackers leveraged APIs like https://logo.clearbit.com/[company domain] to integrate authentic logos into phishing sites. This seamless branding approach increased user trust and made phishing attempts harder to detect.
To evade detection, attackers used:
Victims were redirected to phishing pages that appeared legitimate, with pre-filled email addresses further enhancing the illusion of authenticity. Once users entered their credentials, the stolen data was sent to Command-and-Control (C2) servers or Telegram bots via API endpoints.
The phishing sites contained JavaScript snippets that transmitted stolen credentials using Base64 encoding, effectively hiding the data during analysis. Group-IB analysts observed: “The JSON response from Telegram’s API confirms that the stolen credentials were successfully sent to a private chat controlled by the attacker.”
Group-IB warns that these techniques signify a continuous evolution in phishing methodologies: “Threat actors are quickly adapting, constantly refining and improving their techniques to bypass security measures and exploit vulnerabilities.”
This campaign serves as a stark reminder of the ever-evolving nature of cyber threats. Organizations must strengthen their defenses and educate employees to identify and respond to increasingly sophisticated phishing attempts.
