 Source:  BlackPlague Malware Steals Discord Token & Telegram Sessions (cybersecuritynews.com) With online messaging applications being a mainstay of modern interpersonal communications, it is no surprise that malicious actors would seek to exploit and compromise them to achieve their various objectives. With that in mind, the BlackPlauge malware is only the latest iteration of this trend, as it  was specifically engineered  to target the popular messaging and communications platforms Discord and Telegram. Stealing session data and user tokens is the name of the game for this version of the malware, and its sophisticated approach embodies a critical threat to the confidentiality and integrity of countless users of these communication platforms worldwide.  BlackPlague's approach leverages vulnerabilities found in the communications platforms themselves, from which it can then pivot and extract session data, user tokens, and similar sensitive information from ...

 Source:  Cybersecurity researchers spotlight a new ransomware threat – be careful where you upload files (msn.com) Recently, researchers in the field of cybersecurity have uncovered a new ransomware threat that exploits the file upload capabilities of modern web browsers like Google Chrome and Microsoft Edge. This novel threat perfectly encapsulates the critical importance surrounding the security of APIs, as they play a central role in the exploitation process. Through the File System Access API, which allows web applications to interact with local users' file systems, attackers can leverage it to maliciously access local files, encrypt them, and demand a ransom from their victims. However, the sad reality is that even when a payment  is made  successfully, attackers are under no obligation to restore end-user access and, more often than not, tend to simply take the money without performing the service advertised to their victim.  The origins of this threat em...

 Source:  Hackers Exploited GitHub and FileZilla to Deliver Banking Malware (cybersecuritynews.com) According to the Inskit Group at Recorded Future, activities by Russian-speaking threat actors originating from the Commonwealth of Independent States (CIS) have been uncovered as the primary source behind the spread of sophisticated banking malware through GitHub and FileZilla. Despite being known as relatively secure collaboration platforms, their exploitation to spread sophisticated malware and malicious payloads throughout the internet poses a significant threat to both personal and business security.  The methodology used by the attackers revolved around creating fake Github accounts and repositories that mimicked legitimate software offerings such as Bartender 5 and Pixelmator Pro. Subsequently, they opted to instead populate their spoofed repositories with malicious software such as Atomic MacOS Stealer (AMOS) and Vidar, which were designed to steal sensitive informa...

 Source:  Iranian MOIS-Linked Hackers Behind Destructive Attacks on Albania and Israel (thehackernews.com) Recent revelations have uncovered a worrying trend surrounding Iranian hackers linked to their Ministry of Intelligence and Security (MOIS), namely that they've been the main suspects behind destructive cyberattacks targeting Albania and Israel. These threat actors, also known as 'Void Manticore,' have been utilizing a wiper malware to target critical systems in both countries whilst self-identifying themselves as 'Homeland Justice' and 'Karma.' The threat actors' patterns also display a striking correlation with geopolitical events involving Israel, Albania, and Iran, as attacks targeting the latter victim country had been ongoing since July 2022, while attacks against the former had only begun in earnest following the Israel-Palestine war in October 2023.  Void Manticore's attacks have caused significant disruption, as they've been charact...

 Source:  From Document to Script: Insides of Darkgate's Campaign (forcepoint.com) A recent analysis by Forcepoint's X-labs has uncovered a worrying threat vector through which cyber threats can target users , namely  through commonly shared documents, namely those in XLSX, PDF, and HTML formats.  These are a natural choice for any attacker primarily because of their sheer ubiquity. They represent trustable file formats for the average end user, who typically would open one upon receiving it with no hesitation or second thoughts. However, the research by X-labs has uncovered a phishing campaign called DarkGate, which utilizes a sophisticated attack methodology in which phishing emails containing standard file formats are just the start of a process, which often culminates in remote code execution and the hijacking of user machines. Notably, the campaign's bait of choice to target users are emails that appear to be invoices from 'Intuit QuickBooks', containing a PDF ...

 Source:  New Wi-Fi Vulnerability Enables Network Eavesdropping via Downgrade Attacks (thehackernews.com) Cybersecurity researchers have recently uncovered a vulnerability that currently impacts one of the most ubiquitous means of internet connectivity, namely the IEEE 802.11 Wi-Fi standard. This vulnerability allows attackers to use downgrade attacks to eavesdrop on traffic traversing the network, which can have broad implications for the confidentiality, integrity, and availability of the data in networks that are targeted by such attacks. Officially known as SSID confusion and tracked by MITRE as CVE-2023-52424, its scope is comprehensive, as all operating systems and Wi-Fi clients are vulnerable to exploitation. Most notably, the usage of more or less advanced Wi-Fi encryption protocols makes little difference, as clients using WPA3, WEP, 802.11X/EAP, and AMPE protocols are all affected by the attack, irrespective of their technical differences.  Regarding its technic...

Source:  30+ Tesla Cars Hacked Globally Using Third-Party Software (cybersecuritynews.com) Following up on our most recent blog post regarding the threat posed by misconfigurations, a recent incident impacting Tesla places those findings under a brighter spotlight. Due to vulnerabilities caused by misconfigurations in TeslaLogger, a third-party software used for data logging, security researcher Harish SG uncovered that  its insecure default settings could be exploited  to gain unauthorized access. After Harish discovered the issue, it  was reported  to the platform's maintainer, who  is expected  to have taken actions to mitigate or resolve that risk.  It is essential to clarify that the vulnerability and potential remote access associated with it did not reside in Tesla's vehicles or in Tesla's infrastructure but rather stemmed from misconfigurations surrounding the use of default credentials and improper storage of API keys by TeslaLogger. Desp...
