North Korean hackers, specifically the Kimsuky APT group (also known as Emerald Sleet), have been observed employing a new tactic to compromise targets. The group is tricking individuals into running PowerShell as an administrator, then instructing them to paste and execute malicious code they provide. The threat actor masquerades as a South Korean government official, building rapport before sending a spear-phishing email with a PDF attachment containing instructions to open PowerShell as an administrator and paste a specific code snippet.
If the target executes the code, it downloads and installs a browser-based remote desktop tool along with a certificate and PIN. The code then sends a web request to register the victim device, granting the threat actor access for data exfiltration. Microsoft Threat Intelligence has observed this tactic in limited attacks since January 2025, describing it as a departure from the threat actor's usual tradecraft. Recommended read:

A newly uncovered ClickFix phishing campaign is tricking victims into executing malicious PowerShell commands, which subsequently deploy the Havok post-exploitation framework. This framework grants attackers remote access to compromised devices. The attackers cleverly conceal the different stages of their malware within SharePoint sites and employ a modified version of Havoc Demon in tandem with the Microsoft Graph API. This tactic is used to obfuscate command-and-control (C2) communications, making them appear as legitimate traffic within trusted Microsoft services.
The attack starts with a phishing email that has a HTML attachment, when opened, displays an error message, which uses the ClickFix technique to trick users into copying and executing a malicious PowerShell command into their terminal or PowerShell, thereby triggering the next-stage. The command downloads and executes a PowerShell script hosted on a server controlled by the attacker. This script checks for sandboxed environments, downloads the Python interpreter if needed, and executes a Python script serving as a shellcode loader for KaynLdr, launching the Havoc Demon agent on the infected host.

Cybersecurity researchers have revealed a sophisticated campaign where hackers are exploiting Microsoft Teams and Quick Assist for remote access. The attacks have been attributed to ransomware groups such as Black Basta and Cactus, highlighting a growing trend of cybercriminals abusing legitimate tools to bypass security defenses and infiltrate corporate networks. The attackers use social engineering tactics, including email flooding, followed by direct contact via Microsoft Teams, impersonating IT support staff to trick victims into granting access through Microsoft’s Quick Assist tool.
Once inside, attackers deploy additional malware by abusing OneDriveStandaloneUpdater.exe, a legitimate Microsoft process. By sideloading malicious DLLs, they establish persistent control and use BackConnect malware for command-and-control communication. This campaign has impacted various regions and industries, with a significant number of incidents occurring in North America, particularly the United States, and Europe. Manufacturing, financial services, and real estate sectors have been particularly targeted, as these threat actors are actively working around conventional security measures. Recommended read:

New York-based venture capital and private equity firm Insight Partners has disclosed a security breach of its systems. The firm, which manages over $90 billion in regulatory assets and has invested in over 800 software and technology startups globally over the past 30 years, revealed that the incident occurred in January. The breach involved unauthorized access to its information systems following what they are calling "a sophisticated social engineering attack."
Insight Partners confirmed that the attack took place on January 16, 2025. The company has taken steps to address the situation, notifying law enforcement in relevant jurisdictions and engaging third-party cybersecurity experts to investigate the full scope and impact of the breach. The investigation is ongoing to determine the extent of data exposure and to implement measures to prevent future incidents. Recommended read:
