Today’s hottest cybersecurity news stories:
⚠️ iPhone users: Beware of fake ‘lockdown mode’ attack 📱
🎧 New ‘BLUFFS’ bluetooth attack leaves devices exposed 🚪
🤖 Russian bots target Germany, Ukraine, & US with disinfo 🤥
A new "post-exploitation tampering technique" discovered by Jamf Threat Labs exposes how hackers can visually deceive iPhone users into thinking their device is in Lockdown Mode when it's not, enabling covert attacks.
📱 Lockdown Mode 🔒
FYI: Introduced by Apple in iOS 16 last year, Lockdown Mode stands as a robust security feature 📱. Its primary goal is to shield high-risk individuals from advanced digital threats, including mercenary spyware, by reducing the potential areas of attack. 🛡️ Lockdown Mode minimises the attack surface, enhancing device security and protecting users from sophisticated cyber threats.
👾 Bypassing Lockdown Mode 🔓
Back to the threat… Once infiltrated, hackers can trigger a 'bypass' of Lockdown Mode, creating a Fake Lockdown Mode on compromised devices. Unpatched security flaws are potential entry points for such attacks.
🛡️ Lockdown Mode Vulnerabilities Revealed 🌐
While Lockdown Mode was introduced for enhanced security in iOS 16 and elevated to kernel level in iOS 17, this novel method exposes vulnerabilities that allow persistent malware existence even after a user-initiated reboot.
🤔 Safari Browser at Risk: PDF Access Enabled 🌐
The report highlights that adversaries can manipulate Lockdown Mode on Safari, potentially giving access to blocked PDF files, posing additional risks to user data.
🚨 Stay Vigilant and Update Your Devices! 🚨
In light of this threat, it's crucial to stay vigilant, update your devices promptly, and exercise caution to protect against potential security breaches.
In the competitive landscape of software business, optimizing processes and leveraging efficiencies can make a significant difference in building a strong pipeline and closing revenue faster.

New research has unveiled BLUFFS, a series of vulnerabilities impacting Bluetooth Core Specifications 4.2 through 5.4, tracked under CVE-2023-24023 (CVSS score: 6.8). These vulnerabilities break forward and future secrecy guarantees, creating adversary-in-the-middle (AitM) scenarios.
🔍 Understanding the Threat 👤
EURECOM researcher Daniele Antonioli explains that the attacks enable device impersonation and machine-in-the-middle by compromising just one session key. This is achieved by exploiting flaws in the Bluetooth session key derivation mechanism, allowing the derivation of the same key across sessions.
🚨 Real-Time Encryption Key Brute-Force 💪
The AitM attacker can negotiate connections and force the lowest encryption key length, potentially allowing live injection attacks on traffic between vulnerable Bluetooth peers. Successful attacks require the attacking device to be within wireless range during a pairing procedure.
🛡️ Protecting Your Devices 📱
Bluetooth Special Interest Group (SIG) recommends rejecting connections with key strengths below 7 octets, operating in "Secure Connections Only Mode," and using "Secure Connections" mode for pairing. These measures aim to limit the impact of session key reuse and enhance overall security.
🌐 The Cybersecurity Landscape 🏞️
These revelations highlight the importance of staying informed and implementing recommended mitigations to safeguard against emerging threats. Be cautious during Bluetooth pairing and ensure secure practices.

A new report reveals that the Russia-linked influence operation, Doppelganger, has been actively targeting Ukrainian, U.S., and German audiences. Meta describes it as the "largest and most aggressively-persistent Russian-origin operation."
📰 Inauthentic Campaigns and AI Tactics 👨💻
Doppelganger employs inauthentic news sites and social media accounts to spread anti-Ukrainian propaganda, anti-LGBTQ+ sentiment, and undermine U.S. military competence and Germany's economic and social issues. The influence operation, active since February 2022, uses brandjacking and advanced obfuscation techniques, including AI-generated news articles.
🔄 Evolving Tactics and AI-Powered Disinformation 🤖
Doppelganger's tactics are evolving, utilising over 800 social media accounts for the Ukraine campaign. The use of inauthentic media outlets, such as Election Watch and Warfare Insider, exemplifies the adaptability of Russian information warfare.
🚨 Meta's Warning and Disruptions ⚠️
Meta's Adversarial Threat Report highlights Doppelganger's influence in U.S. and European political affairs. They discovered new websites focusing on migration and border security. Meta disrupted three covert influence operations in Q3 2023 but raised concerns about paused threat sharing, limiting efforts against malicious foreign campaigns.
🔒 Stay Vigilant Against Deceptive Campaigns! 😈
Doppelganger's tactics showcase the enduring nature of Russian information warfare. Stay informed, be cautious of misleading content, and ensure your cybersecurity measures are up to date.
