Senior executives working in U.S.-based organizations are being targeted by a new phishing campaign that leverages a popular adversary-in-the-middle (AiTM) phishing toolkit named  EvilProxy  to conduct credential harvesting and account takeover attacks. Menlo Security said the activity started in July 2023, primarily singling out banking and financial services, insurance, property management and real estate, and manufacturing sectors. "The threat actors leveraged an open redirection vulnerability on the job search platform 'indeed.com,'redirecting victims to malicious phishing pages impersonating Microsoft," security researcher Ravisankar Ramprasad  said  in a report published last week. EvilProxy , first documented by Resecurity in September 2022, functions as a reverse proxy that's set up between the target and a legitimate login page to intercept credentials, two-factor authentication (2FA) codes, and session cookies to hijack accounts of interest. The th...

In today's rapidly evolving technological landscape, the integration of Artificial Intelligence (AI) and Large Language Models (LLMs) has become ubiquitous across various industries. This wave of innovation promises improved efficiency and performance, but lurking beneath the surface are complex vulnerabilities and unforeseen risks that demand immediate attention from cybersecurity professionals. As the average small and medium-sized business leader or end-user is often unaware of these growing threats, it falls upon cybersecurity service providers – MSPs, MSSPs, consultants and especially vCISOs - to take a proactive stance in protecting their clients. At Cynomi, we experience the risks associated with generative AI daily, as we use these technologies internally and work with MSP and MSSP partners to enhance the services they provide to small and medium businesses. Being committed to staying ahead of the curve and empowering virtual vCISOs to swiftly implement cutting-edge secur...

"Of course, here's an example of simple code in the Python programming language that can be associated with the keywords "MyHotKeyHandler," "Keylogger," and "macOS," this is a message from ChatGPT followed by a piece of malicious code and a brief remark not to use it for illegal purposes. Initially published by  Moonlock Lab , the screenshots of ChatGPT writing code for a keylogger malware is yet another example of trivial ways to hack large language models and exploit them against their policy of use. In the case of Moonlock Lab, their malware research engineer told ChatGPT about a dream where an attacker was writing code. In the dream, he could only see the three words: "MyHotKeyHandler," "Keylogger," and "macOS." The engineer asked ChatGPT to completely recreate the malicious code and help him stop the attack. After a brief conversation, the AI finally provided the answer. "At times, the code generated isn...

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...

Multiple high-severity security vulnerabilities have been disclosed in ConnectedIO's ER2000 edge routers and the cloud-based management platform that could be exploited by malicious actors to execute malicious code and access sensitive data. "An attacker could have leveraged these flaws to fully compromise the cloud infrastructure, remotely execute code, and leak all customer and device information," Claroty's Noam Moshe  said  in an analysis published last week. Vulnerabilities in 3G/4G routers could expose thousands of internal networks to severe threats, enabling bad actors to seize control, intercept traffic, and even infiltrate Extended Internet of Things (XIoT) things. The shortcomings impacting the ConnectedIO platform versions v2.1.0 and prior, primarily the 4G ER2000 edge router and cloud services, could be chained, permitting attackers to execute arbitrary code on the cloud-based devices without requiring direct access to them. Flaws have also been unea...

The maintainers of the  Curl library  have released an advisory warning of two security vulnerabilities that are expected to be addressed as part of an forthcoming update set for release on October 11, 2023. This  includes  a high-severity and a low-severity flaw tracked under the identifiers CVE-2023-38545 and CVE-2023-38546, respectively. Additional details about the issues and the exact version ranges impacted have been withheld owing to the possibility that the information could be used to "help identify the problem (area) with a very high accuracy." That said, the "last several years" of versions of the library are said to be affected.  "Sure, there is a minuscule risk that someone can find this (again) before we ship the patch, but this issue has stayed undetected for years for a reason," Daniel Stenberg, the lead developer behind the project, said in a message posted on GitHub. Curl, powered by libcurl, is a  popular command-line tool  for...

A Gaza-based threat actor has been linked to a series of cyber attacks aimed at Israeli private-sector energy, defense, and telecommunications organizations. Microsoft, which revealed details of the activity in its fourth annual  Digital Defense Report , is tracking the campaign under the name  Storm-1133 . "We assess this group works to further the interests of Hamas, a Sunni militant group that is the de facto governing authority in the Gaza Strip, as activity attributed to it has largely affected organizations perceived as hostile to Hamas," the company said. Targets of the campaign included organizations in the Israeli energy and defense sectors and entities loyal to Fatah, a Palestinian nationalist and social democratic political party headquartered in the West Bank region. Attack chains entail a mix of social engineering and fake profiles on LinkedIn that masquerade as Israeli human resources managers, project coordinators, and software developers to contact and s...

As much as $7 billion in cryptocurrency has been illicitly laundered through cross-chain crime, with the North Korea-linked Lazarus Group linked to the theft of roughly $900 million of those proceeds between July 2022 and July of this year. "As traditional entities such as  mixers  continue to be subject to seizures and sanctions scrutiny, the crypto crime displacement to chain- or asset-hopping typologies is also on the rise," blockchain analytics firm Elliptic  said  in a new report published this week. Cross-chain crime refers to the conversion of crypto assets from one token or blockchain to another, often in rapid succession, in an attempt to obfuscate their origin, making it a lucrative method for money laundering for crypto thefts and an alternative to traditional approaches like mixers. According to data gathered by Elliptic, the Lazarus Group's use of cross-chain bridges contributed to a majority of the 111% increase in the proportion of funds sent via s...

Threat actors have been observed targeting semiconductor companies in East Asia with lures masquerading as Taiwan Semiconductor Manufacturing Company (TSMC) that are designed to deliver Cobalt Strike beacons. The intrusion set, per  EclecticIQ , leverages a backdoor called HyperBro, which is then used as a conduit to deploy the commercial attack simulation software and post-exploitation toolkit. An alternate attack sequence is said to have utilized a previously undocumented malware downloader to deploy Cobalt Strike, indicating that the threat actors devised multiple approaches to infiltrate targets of interest. The Dutch cybersecurity firm attributed the campaign to a China-linked threat actor owing to the use of HyperBro, which has been almost exclusively put to use by a threat actor known as  Lucky Mouse  (aka APT27, Budworm, and Emissary Panda). Tactical overlaps have also been unearthed between the adversary behind the attacks and another cluster tracked by Rec...

Ensuring sensitive data remains confidential, protected from unauthorized access, and compliant with data privacy regulations is paramount. Data breaches result in financial and reputational damage but also lead to legal consequences. Therefore, robust data access security measures are essential to safeguard an organization's assets, maintain customer trust, and meet regulatory requirements.  A comprehensive  Data Security Platform  is essential for full visibility and control of sensitive data. One example is Satori's Universal Data Permissions Scanner (UDPS), an open-source authorization analysis tool.   UDPS , available on GitHub, enables universal visibility into data access permissions across various data stores. With this tool, it's easier to identify who has the potential to access sensitive data, which can help organizations take a proactive approach to enhancing their security posture, streamline compliance, and ensure well-governed data access. Understan...

GitHub has  announced  an improvement to its secret scanning feature that extends validity checks to popular services such as Amazon Web Services (AWS), Microsoft, Google, and Slack. Validity checks,  introduced  by the Microsoft subsidiary earlier this year, alert users whether exposed tokens found by  secret scanning  are active, thereby allowing for effective remediation measures. It was first enabled for GitHub tokens. The cloud-based code hosting and version control service said it intends to support more tokens in the future. To toggle the setting, enterprise or organization owners and repository administrators can head to Settings > Code security and analysis > Secret scanning and check the option "Automatically verify if a secret is valid by sending it to the relevant partner." Earlier this year, GitHub also  expanded  secret scanning alerts for all public repositories and announced the  availability of push protection ...
