How Russian Spies Are Analyzing Data From China’s WeChat App

Moscow's skepticism towards foreign messaging applications has intensified, particularly regarding the Chinese app WeChat, which has weak encryption protocols. Russian counterintelligence is analyzing WeChat data to identify individuals in contact with Chinese operatives. A recent intelligence document reveals concerns about China's influence in Russia, particularly as Russia's isolation from the West grows due to geopolitical tensions. The F.S.B. is using an analytical tool called "Skopishche" to enhance surveillance, aggregating data from sources like WeChat, including account logins, contact lists, and message archives. This data is often collected from mobile devices seized from significant individuals. The shared focus on surveillance by Russian and Chinese authorities highlights their concerns about external influences and internal dissent.

Fake DocuSign and Gitcode sites are tricking victims into downloading malware – here’s what you need to know

Researchers at DomainTools Investigations (DTI) have identified counterfeit websites mimicking platforms like DocuSign and Gitcode, designed to lure users into downloading malware, specifically a remote access trojan (RAT). These fraudulent sites use tactics such as fake CAPTCHA prompts to enhance credibility and prompt users to download malicious software disguised as necessary updates. The operation employs a multi-stage downloader PowerShell script, reminiscent of older scams that alarmed users with popups about virus infections. Users are advised to be cautious with unfamiliar websites and verify the authenticity of download prompts.

Do I need an antivirus and a VPN?

Reliance on antivirus software for device protection is common, but certain threats, especially ransomware, can bypass even the best solutions. Cybercriminals have shifted tactics from encrypting data for ransom to exfiltrating sensitive information and threatening to leak it. The availability of ransomware kits and the use of AI by attackers have made cybercrime more accessible and targeted. Remote work environments increase vulnerabilities, as hackers exploit unsecured networks and personal devices. Antivirus software can help protect against malware and viruses, but built-in solutions often lack comprehensive security. A high-quality antivirus program can enhance protection through advanced features and AI. A Virtual Private Network (VPN) encrypts data and secures internet traffic, making it a valuable tool for cybersecurity. Implementing a VPN is cost-effective compared to potential data breach costs. Using both a VPN and antivirus software is essential for comprehensive coverage, as they address different security aspects. Businesses may need advanced endpoint protection solutions for heightened security, which continuously scans for suspicious behavior and integrates multiple security features. Despite these tools, proper personal practices and cybersecurity awareness are crucial to minimize vulnerabilities and human error, which is a leading cause of cyberattacks.

Watch out – that antivirus website could be a fake, and infecting your PC with malware

Researchers have discovered a fraudulent website, "bitdefender-download[.]com," posing as Bitdefender antivirus, which is used to distribute the VenomRAT Remote Access Trojan. The site, hosted on an Amazon S3 bucket, tricks users into downloading harmful software through an executable file named "StoreInstaller.exe," which is linked to VenomRAT and contains code from post-exploitation frameworks SilentTrinity and StormKitty stealer. VenomRAT allows cybercriminals to gain unauthorized control over Windows systems, steal sensitive information, log keystrokes, access webcams, and execute commands remotely. The primary goal of this campaign is to steal cryptocurrency by compromising credentials and crypto wallets. The investigation also found connections to other fraudulent operations impersonating banks and IT services, including the Armenian IDBank and the Royal Bank of Canada.

M&S shoppers urged to set up security measure on ‘all accounts’

M&S shoppers are being urged to enhance their online security following a cyber attack that disrupted customer services. The retailer has acknowledged ongoing challenges, stating they cannot process online orders while stores remain open. Sensitive customer information, including phone numbers, email addresses, and order histories, was compromised in the breach. Security expert Luis Corrons from Norton recommends activating two-step verification for online accounts, being cautious about stored personal and payment information, deleting unused accounts, using strong passwords, and keeping devices and software updated to improve security. He emphasizes that cyber threats are increasingly targeting human behavior and that these security measures are essential for digital safety.

This Stealthy Malware Takes Control of Your Computer to Steal Your Data

Skitnet is a new malware that targets personal data by stealthily infiltrating computer systems. It is used by hackers to steal sensitive information through advanced methods, including the insertion of invisible malicious code in emails and the creation of fraudulent websites. Cybersecurity experts from PRODAFT have revealed that Skitnet is often employed by ransomware groups and can remotely control infected computers using services like AnyDesk. The malware operates discreetly, monitoring user actions without detection for extended periods, making it difficult for victims to realize they are infected until after data theft occurs. To protect against such threats, security specialists recommend identifying suspicious emails, using reliable antivirus software, and enhancing account security with two-step verification and strong passwords.

Hackers Exploit PyBitmessage Library to Evade Antivirus and Network Security Detection

The AhnLab Security Intelligence Center (ASEC) has identified a new strain of backdoor malware that works with a Monero coin miner, utilizing the PyBitmessage library for covert P2P communications. This malware uses encryption to secure data exchanges and anonymize identities, complicating detection by security tools. It decrypts resources using XOR operations to deploy a Monero miner and a backdoor component. The Monero miner exploits the cryptocurrency's anonymity, while the backdoor, created with PowerShell, installs PyBitmessage and retrieves files from GitHub or a Russian file-sharing platform. Commands are executed as PowerShell scripts, making detection difficult. The malware may be distributed as legitimate software or cracked files. ASEC advises caution with unverified files and recommends keeping security solutions updated.

Hackers can disable Windows Defender

A new tool called Defendnot can disable Windows Defender by masquerading as another antivirus program, exploiting a limitation of the Windows operating system that prevents multiple antivirus solutions from running simultaneously. When Defendnot is installed, Windows automatically disables Defender, leaving systems vulnerable. Cybersecurity experts recommend using robust antivirus solutions like TotalAV for additional security.

Windows Server Flaw a Shortcut to Privilege Escalation

An unpatched vulnerability in Windows Server 2025, identified by Akamai researchers, is associated with a method called "BadSuccessor." This flaw, considered "trivial" to exploit and present in the default configuration, allows for privilege escalation and potential full domain compromise. The vulnerability arises from delegated managed service accounts (dMSA), which were intended to enhance security during the migration of legacy service accounts. However, dMSAs can inherit permissions from legacy accounts, enabling attackers to simulate a migration and gain access to the permissions and encryption keys of those accounts without verification. The attack requires prior permissions within an Active Directory organizational unit, indicating a previous breach. Akamai reported the vulnerability to Microsoft on April 1, but Microsoft classified its severity as "moderate." Akamai recommends organizations restrict the creation of dMSAs to mitigate risks associated with this vulnerability.
