Hackers Exploit 70+ Microsoft Exchange Servers to Deploy Keyloggers for Credential Theft

June 24, 2025
Vulnerability / Malware

Unidentified threat actors have been targeting publicly exposed Microsoft Exchange servers to inject malicious code into login pages for credential harvesting. A recent analysis by Positive Technologies revealed two types of JavaScript keyloggers on the Outlook login page: one that saves captured data to a locally accessible file and another that transmits it directly to an external server. The Russian cybersecurity firm reported that these attacks affected 65 victims across 26 countries and continue a campaign first noted in May 2024, which targeted organizations in Africa and the Middle East. Initial findings indicated at least 30 victims among government agencies, banks, IT firms, and educational institutions, with evidence of compromises dating back to 2021. The attack chains exploit known vulnerabilities in Microsoft systems.

Cybercriminals Utilize Open-Source Tools to Target Financial Institutions in Africa

Threat Intelligence / Ransomware

Cybersecurity experts are highlighting a wave of cyberattacks aimed at financial institutions across Africa, dating back to at least July 2023. These attacks leverage a combination of open-source and publicly available tools to sustain access. Researchers from Palo Alto Networks’ Unit 42 are monitoring this activity under the label CL-CRI-1014, where “CL” stands for “cluster” and “CRI” signifies “criminal motivation.” The primary objective appears to be gaining initial access to systems, which is then sold to other criminal actors in underground forums, effectively turning the threat actor into an initial access broker (IAB). “The threat actor mimics signatures from legitimate applications to create forged file signatures, camouflaging their toolset and concealing malicious activities,” noted researchers Tom Fakterman and Guy Levi. “Threat actors frequently spoof legitimate products for illicit purposes.” The attacks are marked by the use of tools such as PoshC2 and others.

U.S. Agencies Issue Warning About Increased Iranian Cyber Threats Targeting Defense and Critical Infrastructure

Date: June 30, 2025
Topic: Cybersecurity / Critical Infrastructure

U.S. cybersecurity and intelligence agencies have released a joint advisory cautioning about the rising risk of cyber attacks from Iranian government-sponsored or affiliated groups. “In recent months, we’ve observed heightened activity from hacktivists and Iranian-linked actors, likely to escalate due to current geopolitical circumstances,” the agencies stated. They highlighted that these cyber adversaries typically exploit opportunities presented by unpatched or outdated software vulnerable to known Common Vulnerabilities and Exposures, as well as the use of default or easily guessed passwords on internet-connected accounts and devices. Currently, there is no evidence pointing to a coordinated campaign of malicious cyber actions in the U.S. attributed to Iran, according to insights from the Cybersecurity and Infrastructure Security Agency (CISA), the Federal Bureau of Investigation (FBI), the Department of Defense Cyber Crime Center (DC3), and the National Security Agency (NSA). Emphasizing the need for enhanced vigilance…
