A severity flaw impacting industrial cellular routers from Milesight may have been actively exploited in real-world attacks, new findings from VulnCheck reveal. Tracked as  CVE-2023-43261  (CVSS score: 7.5), the vulnerability has been described as a case of information disclosure that affects UR5X, UR32L, UR32, UR35, and UR41 routers before version 35.3.0.7 that could enable attackers to access logs such as httpd.log as well as other sensitive credentials. As a result, this could permit remote and unauthenticated attackers to gain unauthorized access to the web interface, thereby making it possible to configure VPN servers and even drop firewall protections. "This  vulnerability  becomes even more severe as some routers allow the sending and receiving of SMS messages," security researcher Bipin Jitiya, who discovered the issue,  said  earlier this month. "An attacker could exploit this functionality for fraudulent activities, potentially causing financi...

The Computer Emergency Response Team of Ukraine (CERT-UA) has revealed that threat actors "interfered" with at least 11 telecommunication service providers in the country between May and September 2023. The agency is tracking the activity under the name UAC-0165, stating the intrusions led to service interruptions for customers. The starting point of the attacks is a reconnaissance phase in which a telecom company's network is scanned to identify exposed RDP or SSH interfaces and potential entry points. "It should be noted that reconnaissance and exploitation activities are carried out from previously compromised servers located, in particular, in the Ukrainian segment of the internet," CERT-UA  said . "To route traffic through such nodes, Dante, SOCKS5, and other proxy servers are used." The attacks are notable for the use of two specialized programs called POEMGATE and POSEIDON that enable credential theft and remote control of the infected ho...

Cisco has warned of a critical, unpatched security flaw impacting IOS XE software that's under active exploitation in the wild. Rooted in the web UI feature, the zero-day vulnerability is tracked as  CVE-2023-20198  and has been assigned the maximum severity rating of 10.0 on the CVSS scoring system. It's worth pointing out that the shortcoming only affects enterprise networking gear that have the web UI feature enabled and when it's exposed to the internet or to untrusted networks. "This vulnerability allows a remote, unauthenticated attacker to create an account on an affected system with privilege  level 15 access ," Cisco  said  in a Monday advisory. "The attacker can then use that account to gain control of the affected system." The problem impacts both physical and virtual devices running Cisco IOS XE software that also have the HTTP or HTTPS server feature enabled. As a mitigation, it's recommended to disable the HTTP server feature on internet-facin...

Pro-Russian hacking groups have exploited a recently disclosed security vulnerability in the WinRAR archiving utility as part of a phishing campaign designed to harvest credentials from compromised systems. "The attack involves the use of malicious archive files that exploit the recently discovered vulnerability affecting the WinRAR compression software versions prior to 6.23 and traced as CVE-2023-38831," Cluster25  said  in a report published last week. The archive contains a booby-trapped PDF file that, when clicked, causes a Windows Batch script to be executed, which launches PowerShell commands to open a reverse shell that gives the attacker remote access to the targeted host. Also deployed is a PowerShell script that steals data, including login credentials, from the Google Chrome and Microsoft Edge browsers. The captured information is exfiltrated via a legitimate web service webhook[.]site. CVE-2023-38831 refers to a  high-severity flaw  in WinRAR that ...

The Android banking trojan known as  SpyNote  has been dissected to reveal its diverse information-gathering features. Typically spread via SMS phishing campaigns, attack chains involving the spyware trick potential victims into installing the app by clicking on the embedded link, according to F-Secure. Besides requesting invasive permissions to access call logs, camera, SMS messages, and external storage, SpyNote is known for hiding its presence from the Android home screen and the  Recents screen  in a bid to make it difficult to avoid detection. "The SpyNote malware app can be launched via an external trigger," F-Secure researcher Amit Tambe  said  in an analysis published last week. "Upon receiving the intent, the malware app launches the main activity." But most importantly, it seeks accessibility permissions, subsequently leveraging it to grant itself additional permissions to record audio and phone calls, log keystrokes, as well as capture scre...

SaaS Security's roots are in configuration management. An astounding 35% of all security breaches begin with security settings that were misconfigured. In the past 3 years, the initial access vectors to SaaS data have widened beyond misconfiguration management. " SaaS Security on Tap " is a new video series that takes place in Eliana V's bar making sure that the only thing that leaks is beer (maximum), and not SaaS data. This series takes a look at the key concepts within SaaS security and educates organizations on what new threat vectors need to be addressed. The Annual SaaS Security Survey Report: 2024 Plans and Priorities With the increase in SaaS application use, it's no surprise that incidents are up. The SaaS Security on Tap series covers this year's SaaS Security report which found that 55% of organizations have experienced a SaaS security incident within the last two years, including data leaks, data breaches, ransomware attacks, and malicious applications.  The r...

Encrypted messaging app Signal has pushed back against "viral reports" of an alleged zero-day flaw in its software, stating it found no evidence to support the claim. "After responsible investigation *we have no evidence that suggests this vulnerability is real* nor has any additional info been shared via our official reporting channels," it  said  in a series of messages posted in X (formerly Twitter). Signal said it also checked with the U.S. government and that it found no information to suggest "this is a valid claim." It's also urging those with legitimate information to send reports to security@signal[.]org. The development comes as  reports   circulated  over the  weekend  about a zero-day vulnerability in Signal that could be exploited to gain complete access to a targeted mobile device. As a security precaution, it's been advised to turn off  link previews  in the app. The feature can be disabled by going to Signal Settings >...

Threat actors have been observed serving malicious code by utilizing Binance's Smart Chain (BSC) contracts in what has been described as the "next level of bulletproof hosting." The campaign, detected two months ago, has been codenamed  EtherHiding  by Guardio Labs. The novel twist marks the latest iteration in an ongoing malware campaign that leverages compromised WordPress sites to serve unsuspecting visitors a fake warning to update their browsers before the sites can be accessed, ultimately leading to the deployment of information stealer malware such as Amadey, Lumma, or RedLine. "While their initial method of hosting code on abused Cloudflare Worker hosts was taken down, they've quickly pivoted to take advantage of the decentralized, anonymous, and public nature of blockchain," security researchers Nati Tal and Oleg Zaytsev  said . "This campaign is up and harder than ever to detect and take down." It's no surprise that threat act...
