CERT-UA Warns of Phishing Attacks Targeting Ukraine’s Defense and Security Force

CERT-UA Warns of Phishing Attacks Targeting Ukraine's Defense and Security Force

Dec 10, 2024 Malware / Cyber Attack
The Computer Emergency Response Team of Ukraine (CERT-UA) has warned of a new set of cyber attacks that it said were aimed at defense companies in the country as well as its security and defense forces. The phishing attacks have been attributed to a Russia-linked threat actor called UAC-0185 (aka UNC4221), which has been active since at least 2022. "The phishing emails mimicked official messages from the Ukrainian League of Industrialists and Entrepreneurs," CERT-UA said . "The emails advertised a conference held on December 5th in Kyiv, aimed at aligning the products of domestic defense industry companies with NATO standards." The email messages come embedded with a malicious URL that urges the recipients to click on it to view "important information" related to their participation in the conference. But in reality, doing so results in the download of a Windows shortcut file that, upon opening, is designed to execute an HTML Application, which, in t...

Ukraine Bans Telegram Use for Government and Military Personnel

Sep 21, 2024 National Security / Cyber Attack
Ukraine has restricted the use of the Telegram messaging app by government officials, military personnel, and other defense and critical infrastructure workers, citing national security concerns. The ban was announced by the National Coordination Centre for Cybersecurity (NCCC) in a post shared on Facebook. "I have always advocated and advocate for freedom of speech, but the issue of Telegram is not a question of freedom of speech, it is a matter of national security," Kyrylo Budanov, head of Ukraine's GUR military intelligence agency, said . Ukraine's National Security and Defense Council (NSDC) said that Telegram is "actively used by the enemy" to launch cyber attacks, spread phishing messages and malicious software, track users' whereabouts, and gather intelligence to help the Russian military target Ukraine's facilities with drones and missiles. To that end, the use of Telegram has been proscribed on official devices of employees of state ...

How to Protect Your Business from Cyber Threats: Mastering the Shared Responsibility Model

Mar 20, 2025Cloud Security / Data Protection
Cybersecurity isn't just another checkbox on your business agenda. It's a fundamental pillar of survival. As organizations increasingly migrate their operations to the cloud, understanding how to protect your digital assets becomes crucial. The shared responsibility model , exemplified through Microsoft 365's approach, offers a framework for comprehending and implementing effective cybersecurity measures.  The Essence of Shared Responsibility  Think of cloud security like a well-maintained building: the property manager handles structural integrity and common areas, while tenants secure their individual units. Similarly, the shared responsibility model creates a clear division of security duties between cloud providers and their users. This partnership approach ensures comprehensive protection through clearly defined roles and responsibilities.  What Your Cloud Provider Handles  Microsoft maintains comprehensive responsibility for securing the foundational eleme...

GSMA Plans End-to-End Encryption for Cross-Platform RCS Messaging

Sep 18, 2024 Mobile Security / Encryption
The GSM Association (GSMA), the governing body that oversees the development of the Rich Communications Services (RCS) protocol, on Tuesday, said it's working towards implementing end-to-end encryption (E2EE) to secure messages sent between the Android and iOS ecosystems. "The next major milestone is for the RCS Universal Profile to add important user protections such as interoperable end-to-end encryption," Tom Van Pelt, technical director of GSMA, said . "This will be the first deployment of standardized, interoperable messaging encryption between different computing platforms, addressing significant technical challenges such as key federation and cryptographically-enforced group membership." The development comes a day after Apple officially rolled out iOS 18 with support for RCS in its Messages app, which comes with advanced features like message reactions, typing indications, read receipts, and high-quality media sharing, among others. RCS, an impro...

Aug 25, 2024 Law Enforcement / Digital Privacy
Pavel Durov, founder and chief executive of the popular messaging app Telegram, was arrested in France on Saturday, according to French television network TF1. Durov is believed to have been apprehended pursuant to a warrant issued in connection with a preliminary police investigation. TF1 said the probe was focused on a lack of content moderation on the instant messaging service, which the authorities took issue with, turning the app into a haven for various kinds of criminal activity, including drug trafficking, child pornography, money laundering, and fraud. The hands-off approach to moderation on Telegram has been a point of contention , fueling cybercrime and turning the platform into a hub for threat actors to organize their operations, distribute malware, and peddle stolen data and other illegal goods  "This messaging app has transformed into a bustling hub where seasoned cybercriminals and newcomers alike exchange illicit tools and insights creating a dark and well-...

Malicious Ads on Google Target Chinese Users with Fake Messaging Apps

Jan 26, 2024 Malvertising / Phishing-as-a-service
Chinese-speaking users have been targeted by malicious Google ads for restricted messaging apps like Telegram as part of an ongoing malvertising campaign. "The threat actor is abusing Google advertiser accounts to create malicious ads and pointing them to pages where unsuspecting users will download Remote Administration Trojan (RATs) instead," Malwarebytes' Jérôme Segura  said  in a Thursday report. "Such programs give an attacker full control of a victim's machine and the ability to drop additional malware." It's worth noting that the activity, codenamed  FakeAPP , is a continuation of a  prior attack wave  that targeted Hong Kong users searching for messaging apps like WhatsApp and Telegram on search engines in late October 2023. The latest iteration of the campaign also adds messaging app LINE to the list of messaging apps, redirecting users to bogus websites hosted on Google Docs or Google Sites. The Google infrastructure is used to embed link...
