An unpatched security flaw impacting the Edimax IC-7100 network camera is being exploited by threat actors to deliver Mirat botnet malware variants since at least May 2024. The vulnerability in question is CVE-2025-1316 (CVSS v4 score: 9.3), a critical operating system command injection flaw that an attacker could exploit to achieve remote code execution on susceptible devices by means of a specially crafted request. Web infrastructure and security company Akamai said the earliest exploit attempt targeting the flaw dates back to May 2024, although a proof-of-concept (PoC) exploit has been publicly available since June 2023. "The exploit targets the /camera-cgi/admin/param.cgi endpoint in Edimax devices, and injects commands into the NTP_serverName option as part of the ipcamSource option of param.cgi," Akamai researchers Kyle Lefton and Larry Cashdollar said . While weaponizing the endpoint requires authentication, it has been found that the exploitation attempts are...

Malicious actors are exploiting Cascading Style Sheets (CSS), which are used to style and format the layout of web pages, to bypass spam filters and track users' actions. That's according to new findings from Cisco Talos, which said such malicious activities can compromise a victim's security and privacy. "The features available in CSS allow attackers and spammers to track users' actions and preferences, even though several features related to dynamic content (e.g., JavaScript) are restricted in email clients compared to web browsers," Talos researcher Omid Mirzaei said in a report published last week. The insights build upon previous findings from the cybersecurity company about a spike in email threats leveraging hidden text salting in the second half of 2024 with an aim to get around email spam filters and security gateways. This technique particularly entails using legitimate features of the Hypertext Markup Language (HTML) and CSS to include commen...

If you invite guest users into your Entra ID tenant, you may be opening yourself up to a surprising risk.  A gap in access control in Microsoft Entra's subscription handling is allowing guest users to create and transfer subscriptions into the tenant they are invited into, while maintaining full ownership of them.  All the guest user needs are the permissions to create subscriptions in their home tenant, and an invitation as a guest user into an external tenant. Once inside, the guest user can create subscriptions in their home tenant, transfer them into the external tenant, and retain full ownership rights. This stealthy privilege escalation tactic allows a guest user to gain a privileged foothold in an environment where they should only have limited access. Many organizations treat guest accounts as low-risk based on their temporary, limited access, but this behavior, which works as designed, opens the door to known attack paths and lateral movement within the resource t...

From sophisticated nation-state campaigns to stealthy malware lurking in unexpected places, this week's cybersecurity landscape is a reminder that attackers are always evolving. Advanced threat groups are exploiting outdated hardware, abusing legitimate tools for financial fraud, and finding new ways to bypass security defenses. Meanwhile, supply chain threats are on the rise, with open-source repositories becoming a playground for credential theft and hidden backdoors. But it's not all bad news—law enforcement is tightening its grip on cybercriminal networks, with key ransomware figures facing extradition and the security community making strides in uncovering and dismantling active threats. Ethical hackers continue to expose critical flaws, and new decryptors offer a fighting chance against ransomware operators. In this week's recap, we dive into the latest attack techniques, emerging vulnerabilities, and defensive strategies to keep you ahead of the curve. Stay informed, stay sec...

The latest Palo Alto Networks Unit 42 Cloud Threat Report found that sensitive data is found in 66% of cloud storage buckets. This data is vulnerable to ransomware attacks. The SANS Institute recently reported that these attacks can be performed by abusing the cloud provider's storage security controls and default settings. "In just the past few months, I have witnessed two different methods for executing a ransomware attack using nothing but legitimate cloud security features," warns Brandon Evans, security consultant and SANS Certified Instructor. Halcyon disclosed an attack campaign that leveraged one of Amazon S3's native encryption mechanisms, SSE-C, to encrypt each of the target buckets. A few months prior, security consultant Chris Farris demonstrated how attackers could perform a similar attack using a different AWS security feature, KMS keys with external key material, using simple scripts generated by ChatGPT. "Clearly, this topic is top-of-mind for both threat actors and ...

Cybersecurity researchers are calling attention to an incident in which the popular GitHub Action tj-actions/changed-files was compromised to leak secrets from repositories using the continuous integration and continuous delivery (CI/CD) workflow. The incident involved the tj-actions/changed-files GitHub Action, which is used in over 23,000 repositories. It's used to track and retrieve all changed files and directories. The supply chain compromise has been assigned the CVE identifier CVE-2025-30066 (CVSS score: 8.6). The incident is said to have taken place sometime before March 14, 2025. "In this attack, the attackers modified the action's code and retroactively updated multiple version tags to reference the malicious commit," StepSecurity said . "The compromised Action prints CI/CD secrets in GitHub Actions build logs." The net result of this behavior is that should the workflow logs be publicly accessible, they could lead to the unauthorized expo...

Cybersecurity researchers have warned of a malicious campaign targeting users of the Python Package Index (PyPI) repository with bogus libraries masquerading as "time" related utilities, but harboring hidden functionality to steal sensitive data such as cloud access tokens. Software supply chain security firm ReversingLabs said it discovered two sets of packages totaling 20 of them. The packages have been cumulatively downloaded over 14,100 times - snapshot-photo (2,448 downloads) time-check-server (316 downloads) time-check-server-get (178 downloads) time-server-analysis (144 downloads) time-server-analyzer (74 downloads) time-server-test (155 downloads) time-service-checker (151 downloads) aclient-sdk (120 downloads) acloud-client (5,496 downloads) acloud-clients (198 downloads) acloud-client-uses (294 downloads) alicloud-client (622 downloads) alicloud-client-sdk (206 downloads) amzclients-sdk (100 downloads) awscloud-clients-core (206 downloads) creden...

A 51-year-old dual Russian and Israeli national who is alleged to be a developer of the LockBit ransomware group has been extradited to the United States, nearly three months after he was formally charged in connection with the e-crime scheme. Rostislav Panev  was previously arrested in Israel in August 2024. He is said to have been working as a developer for the ransomware gang from 2019 to February 2024, when the operation's online infrastructure was seized in a law enforcement exercise. "Rostislav Panev's extradition to the District of New Jersey makes it clear: if you are a member of the LockBit ransomware conspiracy, the United States will find you and bring you to justice," said United States Attorney John Giordano. LockBit grew to become one of the most prolific ransomware groups, attacking more than 2,500 entities in at least 120 countries around the world. Nearly 1,800 of those were located in the United States. Victims consisted of individuals and ...

The GSM Association (GSMA) has formally announced support for end-to-end encryption (E2EE) for securing messages sent via the Rich Communications Services (RCS) protocol, bringing much-needed security protections to cross-platform messages shared between Android and iOS platforms. To that end, the new GSMA specifications for RCS include E2EE based on the Messaging Layer Security (MLS) protocol via what's called the RCS Universal Profile 3.0 . "The new specifications define how to apply MLS within the context of RCS," Tom Van Pelt, technical director of GSMA, said . "These procedures ensure that messages and other content such as files remain confidential and secure as they travel between clients." This also means that RCS will be the first "large-scale messaging service" to have support for interoperable E2EE between different client implementations from different providers in the near future. It's worth noting that Google's own implemen...
