Stealing Windows passwords is a daunting task that has become alarmingly easy for sophisticated hackers, thanks to the presence of APT 123.

APT 123 targets Windows users specifically, and the methods employed by these malicious actors are as numerous as they are concerning. From infostealer malware routes to email phishing campaigns and state-sponsored advanced persistent threats (APTs), there are countless avenues through which password hackers can infiltrate a system. The poem "How do I attack thee? Let me count the passwords" may seem like a poetic license, but it's a fitting tribute to the numerous attack vectors available to password thieves these days.

One of the most significant challenges in protecting against APT 123 is understanding its true nature and scope. This state-sponsored North Korean hacking group has expanded its attack range far beyond its original South Korean targets, targeting industries across multiple global locations, including Japan, the Middle East, and Vietnam.

The motivations behind Group123's attacks have evolved over time, with ransomware and financial motives now playing a significant role in their strategy. In May 2023, threat intelligence analysts at Cyfirma reported that Group123 is focusing on Windows systems with a particular emphasis on the Windows Credential Manager, which holds the keys to unlocking sensitive credentials.

Group 123 has been observed using custom malware and leveraging Windows application programming interface (API) calls in its ongoing attacks. Initial access is often achieved through phishing email campaigns and exploiting vulnerabilities in Microsoft Office, web servers, and other internet-facing applications. Additionally, the attackers will deploy disk wipers and conduct ransomware operations during some of their campaigns.

What makes it harder to detect Group 123's attackers is their use of evasive tactics, including HTTPS encryption, splitting payloads into multiple stages, checking for defensive tools, and sideloading DLLs. However, by being vigilant and employing the usual mitigations, individuals can protect themselves against these phishing attacks.

To stay safe from Group 123's attacks, it's essential to be on high alert for initial phishing attempts. This means using secure email clients, verifying the authenticity of emails, and avoiding suspicious links or attachments.

Furthermore, individuals can take several additional steps to protect themselves against APT 123:

• Use strong, unique passwords for all accounts
• Enable two-factor authentication (2FA) whenever possible
• Keep operating systems and software up-to-date with the latest security patches
• Use antivirus software and a firewall to detect and block malicious activity
• Be cautious when opening emails or attachments from unknown senders
• Regularly back up important data to prevent losses in case of an attack

While APT 123 poses a significant threat to Windows users, being informed and taking proactive measures can help mitigate the risk. By staying vigilant and employing the necessary security measures, individuals can protect themselves against these sophisticated hackers and keep their sensitive information safe.
