Cybersecurity researchers have discovered an entirely new kind of Linux malware dubbed "CDRThief" that targets voice over IP (VoIP) softswitches in an attempt to steal phone call metadata. "The primary goal of the malware is to exfiltrate various private data from a compromised softswitch, including call detail records ( CDR )," ESET researchers said in a Thursday analysis . "To steal this metadata, the malware queries internal MySQL databases used by the softswitch. Thus, attackers demonstrate a good understanding of the internal architecture of the targeted platform." Softswitches (short for software switches) are generally VoIP servers that allow for telecommunication networks to provide management of voice, fax, data and video traffic, and call routing. ESET's research uncovered that CDRThief targeted a specific Linux VoIP platform, namely the VOS2009 and 3000 softswitches from Chinese company Linknat, and had its malicious functionalit...

Bluetooth SIG—an organization that oversees the development of Bluetooth standards—today issued a statement informing users and vendors of a newly reported unpatched vulnerability that potentially affects hundreds of millions of devices worldwide. Discovered independently by two separate teams of academic researchers, the flaw resides in the Cross-Transport Key Derivation (CTKD) of devices supporting both — Basic Rate/Enhanced Data Rate (BR/EDR) and Bluetooth Low Energy (BLE) standard. Cross-Transport Key Derivation (CTKD) is a Bluetooth component responsible for negotiating the authenticate keys when pairing two Bluetooth devices together, also known as "dual-mode" devices. Dubbed 'BLURtooth' and tracked as CVE-2020-15802 , the flaw exposes devices powered with Bluetooth 4.0 or 5.0 technology, allowing attackers to unauthorizedly connect to a targeted nearby device by overwriting the authenticated key or reducing the encryption key strength. "Dual-mod...

Cybercriminals successfully plundered another digital cryptocurrency exchange. European cryptocurrency exchange Eterbase this week disclosed a massive breach of its network by an unknown group of hackers who stole cryptocurrencies worth 5.4 million dollars. Eterbase, which has now entered maintenance mode until the security issue is resolved, described itself as Europe's Premier Digital Asset Exchange. Based in Bratislava, Slovakia, and launched in 2019, Eterbase is a small cryptocurrency exchange platform that focuses on crypto to SEPA integration (via individual IBAN accounts), multi-asset support, and regulatory compliance. On Monday night, malicious threat actors managed to raid six Eterbase's hot wallets for Bitcoin, Ethereum, XRP, Tezos, Algorand, and TRON and transferred the funds into their wallets managed at six rival crypto exchanges, Eterbase reported on its Telegram channel on Tuesday. According to a tweet posted by the affected exchange, Eterbase t...

IT help desks everywhere are having to adjust to the 'new normal' of supporting mainly remote workers. This is a major shift away from visiting desks across the office and helping ones with traditional IT support processes. Many reasons end-users may contact the helpdesk. However, password related issues are arguably the most common. Since the onset of the global pandemic that began earlier this year, help desks are now dealing with password resets of users who are working remotely. Servicing users who are working remotely and assisting with password resets can be cumbersome and expose organizations to potential security risks. Self-service password reset (SSPR) solutions can significantly assist in providing the tools that remote workers need to service their accounts. However, there can be challenges with enrollment and other issues. Let's take a look at SSPR and see how businesses can manage enrollment compliance. What is Self-Service Password Reset (SSPR)...

A group of researchers has detailed a new timing vulnerability in Transport Layer Security (TLS) protocol that could potentially allow an attacker to break the encryption and read sensitive communication under specific conditions. Dubbed " Raccoon Attack ," the server-side attack exploits a side-channel in the cryptographic protocol (versions 1.2 and lower) to extract the shared secret key used for secure communications between two parties. "The root cause for this side channel is that the TLS standard encourages non-constant-time processing of the DH secret," the researchers explained their findings in a paper. "If the server reuses ephemeral keys, this side channel may allow an attacker to recover the premaster secret by solving an instance of the Hidden Number Problem." However, the academics stated that the vulnerability is hard to exploit and relies on very precise timing measurements and on a specific server configuration to be exploitable. ...
