🚨 Cyber Alerts

1. APT28 RoundPress Webmail Hack Steals Emails

Suspected Russian state-sponsored hackers, identified as APT28, are conducting a global cyberespionage campaign dubbed ‘RoundPress’. This operation targets high-value government organizations across the globe by exploiting flaws in widely used webmail servers. Attackers initiate contact through spear-phishing emails containing malicious JavaScript, which allows them to steal credentials and data merely when an email is opened. The campaign has successfully leveraged multiple cross-site scripting (XSS) vulnerabilities, including zero-days, in webmail products such as Roundcube, MDaemon, and Zimbra.

2. FBI Warns of AI Voice Phishing Scams

The FBI has issued a warning that cybercriminals are now using AI-generated voice deepfakes in phishing campaigns targeting current and former U.S. government officials. These attacks, which began in April 2025, combine voice phishing (vishing) and text messaging (smishing) to impersonate senior officials and manipulate victims into revealing sensitive information or transferring funds. The agency urges the public to treat unsolicited messages from officials with skepticism, as the threat of AI-enhanced deception grows across multiple sectors.

3. Fileless Remcos RAT Delivery Via LNK Files

Researchers have detailed a new Remcos RAT campaign that uses PowerShell loaders and LNK files for fileless deployment. This remote access trojan enables full system control for espionage, operating stealthily in memory to avoid detection. Other threats include a new .NET malware loader and various phishing campaigns delivering info-stealers and RATs. The rise of AI-powered polymorphic attacks further complicates defense, bypassing traditional security measures effectively.
