A long-term cyber intrusion aimed at critical national infrastructure (CNI) in the Middle East has been attributed to an Iranian state-sponsored threat group. The attack, which persisted from May 2023 to February 2025, entailed extensive espionage operations and suspected network prepositioning, a tactic used to maintain persistent access for future strategic advantage. The network security company noted that the attack exhibits tradecraft overlaps with Lemon Sandstorm (formerly Rubidium), also tracked as Parisite, Pioneer Kitten, and UNC757, an Iranian nation-state threat actor active since at least 2017.
The attackers gained initial access by exploiting stolen login credentials to access the victim's SSL VPN system, deploying web shells on public-facing servers, and deploying three backdoors: Havoc, HanifNet, and HXLibrary, for long-term access. They further consolidated their foothold by planting more web shells and an additional backdoor called NeoExpressRAT, using tools like plink and Ngrok to burrow deeper into the network, performing targeted exfiltration of the victim's emails, and conducting lateral movement to the virtualization infrastructure. In response to the victim's initial containment and remediation steps, the attackers deployed more web shells and two more backdoors, MeshCentral Agent and SystemBC. Even after the victim successfully removed the adversary's access, attempts to infiltrate the network continued by exploiting known Biotime vulnerabilities and spear-phishing attacks aimed at employees to harvest Microsoft 365 credentials. Researchers identified an evolving arsenal of tools deployed throughout the intrusion, including both publicly available and custom-developed malware. The custom tools, such as NeoExpressRAT, a Golang-based backdoor with hardcoded command and control communication capabilities, allowed the threat actors to maintain persistent access while evading traditional detection methods.

Cybersecurity firm SentinelOne has become a prime target for state-sponsored threat actors from China and North Korea. SentinelOne, which provides autonomous endpoint protection using AI and machine learning to Fortune 10 and Global 2000 enterprises, government agencies, and managed service providers, is facing persistent cyber espionage and infiltration attempts. A recent analysis by SentinelOne revealed that Chinese actors are actively targeting both the company and its high-value clients, engaging in reconnaissance activities against SentinelOne’s infrastructure and specific organizations they defend.
SentinelOne uncovered a China-nexus threat cluster dubbed PurpleHaze, which conducted reconnaissance attempts against its infrastructure and some of its high-value customers. Researchers first became aware of this group during a 2024 intrusion against an organization that was previously providing hardware logistics services for SentinelOne employees. PurpleHaze is assessed to be a hacking crew with loose ties to another state-sponsored group known as APT15 and has been observed targeting a South Asian government-supporting entity, employing an operational relay box (ORB) network and a Windows backdoor dubbed GoReShell. North Korean actors have also been targeting SentinelOne, attempting to infiltrate the company through a fake IT worker campaign. The company is tracking approximately 360 fake personas and over 1,000 job applications linked to DPRK IT worker operations applying for roles at SentinelOne and SentinelLabs Intelligence. SentinelOne has warned of threat actors targeting its systems and high-value clients, emphasizing that cybersecurity providers are attractive targets due to the potential for significant compromise and the insights into how thousands of environments and millions of endpoints are protected.

The Billbug espionage group, also known as Lotus Blossom, Lotus Panda, and Bronze Elgin, is actively targeting government and critical sectors in Southeast Asia through a coordinated cyber intrusion campaign. Security researchers at Symantec have uncovered that this China-linked group compromised multiple organizations within a single Southeast Asian country between August 2024 and February 2025. The campaign marks a continuation of previously documented attacks in the region, showcasing the persistent threat posed by state-sponsored actors.
The attackers are employing sophisticated techniques, including DLL sideloading, to infiltrate systems. They are exploiting legitimate software from reputable vendors like Trend Micro and Bitdefender to load malicious loaders. Specifically, a Trend Micro binary named tmdbglog.exe is being used to sideload a malicious DLL named tmdglog.dll, which decrypts and executes further malicious code. Similarly, a Bitdefender binary, bds.exe, is abused to sideload a harmful file called log.dll. This DLL decrypts another file, winnt.config, and injects its payload into a Windows system process, systray.exe. The targets of this campaign include a government ministry, an air traffic control organization, a telecommunications provider, and a construction company. Additionally, the group has targeted a news agency in another Southeast Asian country and an air freight organization in a neighboring country. The attackers are using new custom tools, including loaders, credential stealers, and a reverse SSH tool. Indicators of compromise (IOCs) related to Billbug activity have been identified, linking this campaign to the group's known tactics and infrastructure. These findings underscore the need for robust security measures and threat intelligence sharing to defend against such advanced cyber espionage efforts. Recommended read:

A whistleblower at the US National Labor Relations Board (NLRB) has come forward with allegations of a significant cybersecurity breach involving the Department of Government Efficiency (DOGE), overseen by Elon Musk. According to the whistleblower, Daniel Berulis, DOGE operatives arrived at the agency in early March and were granted unrestricted access to internal systems, a move that deviated from standard operating procedures. The whistleblower claims that these DOGE employees ignored infosec rules and were instructed to hand over any requested accounts and stay out of DOGE’s way.
According to the affidavit submitted to the Senate Intelligence Committee, these actions led to a "significant cybersecurity breach" potentially exposing the agency's data to foreign adversaries. The whistleblower also alleges that during their activity, DOGE employees exfiltrated 10GB of data to servers in the US and disabled monitoring tools, raising concerns about potential data exposure. Berulis’s document points out that not even his CIO enjoyed the level of access given to DOGE unit operatives, and that the NLRB already had auditor accounts set up that provided enough privileges to check data without being able to edit, copy, or remove it. The most alarming aspect of the allegations involves attempted access to the NLRB's systems from a Russian IP address using legitimate accounts created by DOGE staffers. These attempts were reportedly blocked, but the valid credentials used suggest a potential compromise. The NPR has reported that the data that DOGE moved could have included sensitive information on unions, ongoing legal cases and corporate secrets. Democratic lawmakers are calling for an investigation into the matter. Recommended read:

A sophisticated phishing campaign, suspected to be backed by Russian Intelligence Services, has been uncovered targeting individuals sympathetic to Ukraine, including Russian citizens and informants. The operation involves creating fake websites impersonating organizations such as the CIA, the Russian Volunteer Corps (RVC), Legion Liberty, and "Hochuzhit" ("I Want to Live"), an appeals hotline for Russian service members operated by Ukrainian intelligence. These deceptive sites aim to collect personal information from unsuspecting visitors, exploiting anti-war sentiment within Russia, where such activities are illegal and punishable by law.
Researchers at Silent Push discovered four distinct phishing clusters using tactics such as static HTML, JavaScript, and Google Forms to steal data. The threat actors are utilizing a bulletproof hosting provider, Nybula LLC, to host the fake websites, which are designed to mimic legitimate organizations. The goal is to gather intelligence and potentially identify dissidents within Russia. The campaign highlights the ongoing digital dimension of the Russia-Ukraine conflict and underscores the need for increased vigilance and improved digital hygiene among potential targets.

A critical unpatched zero-day vulnerability in Microsoft Windows is being actively exploited by 11 state-sponsored threat groups for espionage, data theft, and financially motivated campaigns since 2017. The flaw, tracked as ZDI-CAN-25373, involves the use of crafted Windows Shortcut (.LNK) files to execute hidden malicious commands. This allows attackers to gain unauthorized access to systems, steal sensitive data, and potentially conduct cyber espionage activities targeting governments, private entities, financial organizations, think tanks, telecommunication service providers, and military/defense agencies across multiple countries.
The attacks leverage hidden command line arguments within the malicious .LNK files, making detection difficult by padding the arguments with whitespace characters. Nearly 1,000 .LNK file artifacts exploiting the vulnerability have been found, and linked to APT groups from China, Iran, North Korea, and Russia. In these attacks, the .LNK files act as a delivery vehicle for malware families like Lumma Stealer, GuLoader, and Remcos RAT. Microsoft considers the issue a low severity user interface misrepresentation and does not plan to release a fix. Recommended read:

Blind Eagle, one of Latin America's most dangerous cyber criminal groups, has been actively targeting Colombian institutions and government entities since November 2024. According to Check Point Research (CPR), this advanced persistent threat (APT) group, also tracked as APT-C-36, is using sophisticated techniques to bypass traditional security defenses. They leverage trusted platforms like Google Drive, Dropbox, GitHub, and Bitbucket to distribute their malicious payloads, and have recently been seen using a variant of an exploit for a now-patched Microsoft Windows flaw, CVE-2024-43451. This allows them to infect victims with a high rate of success.
CPR has uncovered that Blind Eagle incorporated this exploit a mere six days after Microsoft released the patch. They use malicious .URL files distributed via phishing emails, and victims are often unaware they are triggering the infection. The final payload is often the Remcos RAT, a remote access trojan that grants attackers complete control over infected systems, allowing for data theft, remote execution, and persistent access. In one campaign in December 2024, over 1,600 victims were affected, highlighting the group's efficiency and targeted approach. Recommended read:
