Cybersecurity firm CYFIRMA says it has identified signs that the North Korea-linked Lazarus group may be preparing a broad cyber campaign aimed at government agencies, financial institutions and other organizations, including potential targets in South Korea. The company said a successful intrusion could create a path to digital-asset theft as well as other follow-on attacks.

In an alert published on Oct. 24, CYFIRMA said it detected the activity two days earlier, on Oct. 22. According to the firm, the operation appears to involve a Korean-speaking hacker attempting to exploit a flaw in PHP, a widely used programming language for web services.

Activity detected across multiple regions

CYFIRMA said the suspected campaign was not limited to one country. The company listed possible targets across South Korea, the United States, Japan, Singapore, Australia and the European Union, with sectors including government agencies, banks, manufacturers and online trading platforms.

The firm attributed the activity to Lazarus, a hacking group widely linked to North Korea. However, it said it had not confirmed either the exact timing of an attack or the specific organizations that would be targeted.

PHP2Shell vulnerability at the center

The campaign is centered on a vulnerability CYFIRMA identified as PHP2Shell. The flaw can allow an attacker to run malicious code on a web server without needing a separate login, a capability that can open the door to deeper access inside a compromised system.

If exploited successfully, such access could be used to steal data, move further into internal networks or prepare additional malicious actions. CYFIRMA assessed the threat level of the activity as “very high.”

Risks include crypto theft, credential theft and ransomware

CYFIRMA warned that a server breach tied to this campaign could be followed by theft of digital assets. The firm also said the same access could be used for credential theft, ransomware deployment and the collection or exfiltration of confidential information.

The warning is notable because the suspected target list includes financial institutions and online trading platforms, both of which can provide access to sensitive account data or digital-asset infrastructure if defenses fail.

Uncertainty remains as defenders are urged to patch

The company said it had also detected indications that artificial intelligence was used during the preparation of the campaign. At the same time, it stressed that key details remain unconfirmed, including when any attack might begin and which entities are actually in scope.

As an immediate defensive measure, CYFIRMA recommended applying relevant security patches and reviewing suspicious activity recorded after Oct. 17. Those steps, based on the firm’s advisory, are the clearest confirmed next actions while the reported threat remains under observation.
