🚨 Cyber Alerts
1. Mastodon Reveals Critical Security Flaw
The decentralized social network, Mastodon, reveals a severe security flaw allowing malicious actors to impersonate and seize any account. Categorized as CVE-2024-23832 with a 9.4 severity rating, the vulnerability was discovered by security researcher Arcanicanis. Mastodon is withholding detailed information until February 15, 2024, urging administrators to update server instances promptly to mitigate exploitation risks and prevent account takeovers.
2. Activator Backdoor MacOS Campaign
Security researchers warn of a large-scale cyberattack using cracked macOS apps to distribute a backdoor, posing a significant risk to both individual users and businesses. The Activator backdoor, discovered by Kaspersky, stands out for its scale and unique multistage delivery method, with threat actors employing cracked business-focused apps as lures. The campaign, potentially aimed at building a macOS botnet, uses a Python backdoor launched directly from the loader script, making it more challenging to detect and remove.
3. Mispadu Banking Trojan Targets Mexico
The Mispadu banking Trojan’s threat actors leverage a patched Windows SmartScreen flaw to compromise users in Mexico, using a new malware variant first observed in 2019. The attacks employ phishing mails, with Mispadu known for targeting victims in the Latin American region. The infection chain utilizes rogue internet shortcut files within bogus ZIP archives, exploiting a now-patched Windows SmartScreen bypass flaw, allowing threat actors to establish contact with a command-and-control server for data exfiltration.
4. SUBTLE-PAWS Backdoor Targets Ukraine
A recent campaign employing the SUBTLE-PAWS PowerShell-based backdoor has been detected, strategically targeting Ukraine with sophisticated evasion tactics and USB drive infection. The ongoing cyber offensive, possibly linked to Shuckworm, focuses on Ukrainian military personnel, utilizing compressed files delivered through potential phishing emails. The PowerShell-based SUBTLE-PAWS backdoor showcases advanced capabilities, including dynamic execution, command and control functions, propagation through removable media, stealth techniques, and environment sensitivity, demonstrating a significant evolution in tactics by threat actors.
5. Cyber Threat Surges with Voicemail Lure
Hackers employ a cunning tactic, utilizing fake voicemail links to trick users into credential theft. Leveraging the familiarity of voicemails tied to corporate email systems, attackers embed malicious hyperlinks disguised as voicemail recordings. This creative approach, observed in 1,000 recent attacks, showcases hackers’ continuous innovation in social engineering, posing a threat to unsuspecting end-users. The technique, mimicking reputable brands and leveraging users’ curiosity about voicemails, serves as a potent method for inducing user participation in phishing attacks, emphasizing the need for heightened cybersecurity awareness.
💥 Cyber Incidents
AnyDesk, a remote desktop software provider, revealed a recent cyber attack on its production systems, emphasizing it’s not a ransomware incident. After detecting the breach through a security audit, the German company revoked security certificates, replaced compromised systems, and is updating code signing certificates. While no evidence suggests end-user systems were affected, the company revoked all web portal passwords, urging users to change them and download the latest software version with a new code signing certificate. Reports indicate threat actors are selling AnyDesk customer credentials on a cybercrime forum, potentially for technical support scams or phishing, highlighting post-incident risks.
The judicial system in Pennsylvania is grappling with a significant challenge as it falls victim to a Distributed Denial of Service (DDoS) attack. This malicious assault has disrupted essential legal processes, causing widespread ramifications for the functioning of the courts. The attack underscores the vulnerability of crucial institutions to cyber threats, raising concerns about the need for enhanced cybersecurity measures to safeguard the integrity and efficiency of the state’s legal system.
The notorious Donut ransomware group expands its target to a key US Department of Defense contractor, issuing a chilling dark web message to DOD contractors. The message claims access to sensitive documents from major defense players like SpaceX, Lockheed Martin, and Boeing, valued at US$20,000. Despite the warning, doubts emerge about the cyberattack’s legitimacy as the targeted defense contractor’s official website remains operational, raising concerns about the credibility of the Donut ransomware group’s claims and the potential national security implications.
The hacktivist group, Anonymous Sudan, orchestrates a relentless cyberattack on Flydubai, a prominent UAE-state-owned airline, with claims of successfully compromising critical digital infrastructure components. Lasting over six hours, the attack targeted key systems, including reservation platforms and the airline’s mobile application. Anonymous Sudan’s ominous message on the dark web hinted at hidden consequences, while the motive behind the audacious Flydubai cyber assault stems from allegations of UAE support to Sudanese rebels, escalating tensions between the hacktivist group and the UAE.
Lurie Children’s Hospital in Chicago grapples with a cyberattack, forcing a shutdown of IT systems and causing disruptions in medical care. The hospital, a critical pediatric care facility, took immediate action to investigate and collaborate with law enforcement. Scheduled procedures are delayed, and essential services are affected, prompting a heightened response to ensure the safety and quality of patient care amidst the cybersecurity incident.
📢 Cyber News
US regulators escalated an investigation into Tesla’s electric vehicle power steering, expanding it to include an engineering analysis of over 334,000 Model 3 and Model Y vehicles. The move is a significant step toward a potential full recall, as thousands of drivers report losing control of their steering wheels, leading to crashes and stranding dozens. This comes amid a series of recalls for Tesla, including one involving 2 million vehicles for dashboard warning lights and another in December related to Autopilot safety concerns.
The United States Secret Service successfully recovers almost $3 million stolen in a business email compromise (BEC) scam targeting the North Carolina Housing Finance Agency (NCHFA). The NCHFA, managing funds from the Homeowner Assistance Fund to aid homeowners during the pandemic, fell victim when two employees received deceptive emails, leading to the transfer of over $2.7 million to a fraudulent account.

The U.S. Treasury Department’s Office of Foreign Assets Control (OFAC) imposes sanctions on six Iranian intelligence officials, members of the IRGC-CEC, for launching cyber attacks on critical infrastructure worldwide. Notable figures include Reza Lashgarian, head of IRGC-CEC, linked to various cyber and intelligence operations. The sanctions come in response to cyber operations involving the hacking of programmable logic controllers, targeting entities like the Municipal Water Authority of Aliquippa in Pennsylvania, emphasizing the global impact of Iranian threat actors on sensitive infrastructure systems.
Microsoft introduces the Linux ‘sudo’ feature to Windows Server 2025, providing administrators with a novel method to elevate privileges for console applications. The ‘sudo’ command, a staple in Linux, allows users to execute commands with elevated privileges while maintaining overall server security. Although leaked in a Windows Server 2025 Insider preview build, the ‘sudo’ settings are still in early development, hinting at potential features like running applications ‘In a new window,’ ‘With input disabled,’ and ‘Inline,’ showcasing Microsoft’s efforts to bridge Linux and Windows functionalities in server environments.
INTERPOL’s collaborative operation, Synergia, targeting phishing, banking malware, and ransomware has identified 1,300 suspicious IP addresses and URLs.
