Senate Website Hit by Second Apparent Defacement, Threat Actor SentinelX Claims Responsibility
The official website of the Philippine Senate appeared to have been targeted by a second defacement incident after a series of unauthorized posts surfaced in its "News Release" section, hours after an earlier defacement claimed by NullSec Philippines.
The newly discovered posts, dated June 10 and June 11, contained messages unrelated to official Senate activities and appeared alongside legitimate government news releases. Among the unauthorized entries were posts titled "Angelica ;pp," "Ashley & Angelica," and "Angelica X Ashley, please patch your system ;pp," containing phrases such as "Your system has been tralalelo tralala" and links to a Facebook profile.
Unlike the earlier NullSec Philippines defacement, which was reportedly removed, the unauthorized posts associated with this latest incident remained publicly accessible as of this writing despite reports that the Senate website had been placed under maintenance.
The incident has been linked to a threat actor identifying as SentinelX, which published a statement criticizing the Senate's cybersecurity measures and alleging that millions of pesos allocated for website security had failed to protect the government portal from compromise.

In a lengthy message posted online, SentinelX claimed that the continued presence of unauthorized content on the Senate website demonstrated serious security weaknesses. The group called for a complete independent audit of the Senate's cybersecurity infrastructure and questioned the effectiveness of security projects reportedly implemented to protect the website.
The apparent defacement allowed unauthorized messages to be published through the Senate's public-facing news release section, raising concerns about possible access to the website's content management system. At present, the full extent of the compromise remains unknown.
No official statement has been released by the Philippine Senate regarding the latest incident, nor has there been confirmation on whether any systems beyond the affected web pages were accessed.
The development marks the second publicly observed security incident involving the Senate website within a matter of hours, following the earlier defacement claimed by NullSec Philippines.
