Tactics, techniques, and procedures (TTPs) form the foundation of modern defense strategies. Unlike indicators of compromise (IOCs), TTPs are more stable, making them a reliable way to identify specific cyber threats. Here are some of the most commonly used techniques, according to ANY.RUN's Q3 2024 report on malware trends, complete with real-world examples. Disabling of Windows Event Logging (T1562.002) Disrupting Windows Event Logging helps attackers prevent the system from recording crucial information about their malicious actions. Without event logs, important details such as login attempts, file modifications, and system changes go unrecorded, leaving security solutions and analysts with incomplete or missing data. Windows Event Logging can be manipulated in different ways, including by changing registry keys or using commands like “net stop eventlog”. Altering group policies is another common method. Since many detection mechanisms rely on log analysis to identify s...

WikiLeaks has today published the 15th batch of its ongoing Vault 7 leak , this time detailing two alleged CIA implants that allowed the agency to intercept and exfiltrate SSH (Secure Shell) credentials from targeted Windows and Linux operating systems using different attack vectors. Secure Shell or SSH is a cryptographic network protocol used for remote login to machines and servers securely over an unsecured network. Dubbed BothanSpy — implant for Microsoft Windows Xshell client, and Gyrfalcon — targets the OpenSSH client on various distributions of Linux OS, including CentOS, Debian, RHEL (Red Hat), openSUSE and Ubuntu. Both implants steal user credentials for all active SSH sessions and then sends them to a CIA-controlled server. BothanSpy — Implant for Windows OS BothanSpy is installed as a Shellterm 3.x extension on the target machine and only works if Xshell is running on it with active sessions. Xshell is a powerful terminal emulator that supports SSH, SFTP, ...

Threat actors of unknown provenance have been attributed to a malicious campaign predominantly targeting organizations in Japan since January 2025. "The attacker has exploited the vulnerability CVE-2024-4577 , a remote code execution (RCE) flaw in the PHP-CGI implementation of PHP on Windows, to gain initial access to victim machines," Cisco Talos researcher Chetan Raghuprasad said in a technical report published Thursday. "The attacker utilizes plugins of the publicly available Cobalt Strike kit 'TaoWu' for-post exploitation activities." Targets of the malicious activity encompass companies across technology, telecommunications, entertainment, education, and e-commerce sectors in Japan. It all starts with the threat actors exploiting the CVE-2024-4577 vulnerability to gain initial access and run PowerShell scripts to execute the Cobalt Strike reverse HTTP shellcode payload to grant themselves persistent remote access to the compromised endpoint. Th...

Cybersecurity leaders aren’t just dealing with attacks—they’re also protecting trust, keeping systems running, and maintaining their organization’s reputation. This week’s developments highlight a bigger issue: as we rely more on digital tools, hidden weaknesses can quietly grow.  Just fixing problems isn’t enough anymore—resilience needs to be built into everything from the ground up. That means better systems, stronger teams, and clearer visibility across the entire organization.

What happens when cybercriminals no longer need deep skills to breach your defenses? Today’s attackers are armed with powerful tools that do the heavy lifting — from AI-powered phishing kits to large botnets ready to strike. And they’re not just after big corporations. Anyone can be a target when fake identities, hijacked infrastructure, and insider tricks are used to slip past security unnoticed. This week’s threats are a reminder: waiting to react is no longer an option. Every delay gives attackers more ground. ⚡ Threat of the Week Critical SAP NetWeaver Flaw Exploited as 0-Day — A critical security flaw in SAP NetWeaver (CVE-2025-31324, CVSS score: 10.0) has been exploited by unknown threat actors to upload JSP web shells with the goal of facilitating unauthorized file uploads and code execution.

Cybersecurity researchers have found a way to exploit a recently disclosed critical flaw in PaperCut servers in a manner that bypasses all current detections. Tracked as  CVE-2023-27350  (CVSS score: 9.8), the issue affects PaperCut MF and NG installations that could be exploited by an unauthenticated attacker to execute arbitrary code with SYSTEM privileges. While the flaw was  patched  by the Australian company on March 8, 2023, the first signs of active exploitation emerged on April 13, 2023. Since then, the vulnerability has been  weaponized  by multiple threat groups, including  ransomware actors , with post-exploitation activity resulting in the execution of PowerShell commands designed to drop additional payloads. Now, VulnCheck has  published  a proof-of-concept (PoC) exploit that sidesteps existing detection signatures by leveraging the fact that "PaperCut NG and MF offer multiple paths to code execution." It's worth noting th...

Today, every unpatched system, leaked password, and overlooked plugin is a doorway for attackers. Supply chains stretch deep into the code we trust, and malware hides not just in shady apps — but in job offers, hardware, and cloud services we rely on every day. Hackers don’t need sophisticated exploits anymore. Sometimes, your credentials and a little social engineering are enough. This week, we trace how simple oversights turn into major breaches — and the silent threats most companies still underestimate. Let’s dive in. ⚡ Threat of the Week UNC5221 Exploits New Ivanti Flaw to Drop Malware — The China-nexus cyber espionage group tracked as UNC5221 exploited a now-patched flaw in Ivanti Connect Secure, CVE-2025-22457 (CVSS score: 9.0), to deliver an in-memory dropper called TRAILBLAZE, a passive backdoor codenamed BRUSHFIRE, and the SPAWN malware suite.
