The financially motivated threat actors behind the  Casbaneiro  banking malware family have been observed making use of a User Account Control ( UAC ) bypass technique to gain full administrative privileges on a machine, a sign that the threat actor is evolving their tactics to avoid detection and execute malicious code on compromised assets. "They are still heavily focused on Latin American financial institutions, but the changes in their techniques represent a significant risk to multi-regional financial organizations as well," Sygnia  said  in a statement shared with The Hacker News. Casbaneiro , also known as Metamorfo and Ponteiro, is best known for its banking trojan, which first emerged in mass email spam campaigns targeting the Latin American financial sector in 2018. Infection chains typically begin with a phishing email pointing to a booby-trapped attachment that, when launched, activates a series of steps that culminate in the deployment of the bankin...

As the number of people using macOS keeps going up, so does the desire of hackers to take advantage of flaws in Apple's operating system.  What Are the Rising Threats to macOS? There is a common misconception among macOS fans that Apple devices are immune to hacking and malware infection. However, users have been facing more and more dangers recently. Inventive attackers are specifically targeting Mac systems, as seen with the "Geacon" Cobalt Strike tool attack. This tool enables them to perform malicious actions such as data theft, privilege elevation, and remote device control, placing the security and privacy of Mac users at grave risk. Earlier this year, researchers also uncovered the MacStealer malware, which also stole sensitive data from Apple users. Documents, iCloud keychain data, browser cookies, credit card credentials – nothing is safe from the prying eyes.  But that's not all. CloudMensis is malicious software that specifically targets macOS systems,...

A set of five security vulnerabilities have been disclosed in the Terrestrial Trunked Radio ( TETRA ) standard for radio communication used widely by government entities and critical infrastructure sectors, including what's believed to be an intentional backdoor that could have potentially exposed sensitive information. The issues, discovered by Midnight Blue in 2021 and held back until now, have been collectively called  TETRA:BURST . There is no conclusive evidence to determine that the vulnerabilities have been exploited in the wild to date. "Depending on infrastructure and device configurations, these vulnerabilities allow for real time decryption, harvest-now-decrypt-later attacks, message injection, user deanonymization, or session key pinning," the Netherlands-based cybersecurity company  said . Standardized by the European Telecommunications Standards Institute (ETSI) in 1995, TETRA is used in more than 100 countries and as a police radio communication system ...

How do you overcome today's talent gap in cybersecurity? This is a crucial issue — particularly when you find executive leadership or the board asking pointed questions about your security team's ability to defend the organization against new and current threats. This is why many security leaders find themselves turning to managed security services like MDR ( managed detection and response ), which can offer an immediate solution. The right MDR partner can act as an extension of your existing team, while offering a fast and budget-friendly option for uplevelling security at organizations of virtually any size. Here's a look at common staffing challenges that MDR helps solve: Overcoming Cybersecurity Talent Challenges From stopping ransomware to securing the attack surface of the environment, most security teams have more to do than they can manage. This leads to security gaps that increase both cyber risk and frustration for stakeholders across the business. The challe...

A new security vulnerability has been discovered in AMD's Zen 2 architecture-based processors that could be exploited to extract sensitive data such as encryption keys and passwords. Discovered by Google Project Zero researcher Tavis Ormandy, the flaw – codenamed  Zenbleed  and tracked as  CVE-2023-20593  (CVSS score: 6.5) – allows data exfiltration at the rate of 30 kb per core, per second. The issue is part of a broader category of weaknesses called  speculative execution attacks , in which the optimization technique widely used in modern CPUs is abused to access cryptographic keys from CPU registers. "Under specific microarchitectural circumstances, a register in 'Zen 2' CPUs may not be written to 0 correctly," AMD  explained  in an advisory. "This may cause data from another process and/or thread to be stored in the YMM register , which may allow an attacker to potentially access sensitive information." Web infrastructure company Cloudflare no...
