Background on PDVSA and its Significance

Petróleos de Venezuela, S.A. (PDVSA) is the Venezuelan state-owned oil and gas company, playing a crucial role in the country’s economy. With vast petroleum reserves, PDVSA is responsible for extracting, refining, and distributing oil within Venezuela and exporting it to international markets. The company’s operations are vital for Venezuela’s economy, providing a significant portion of the country’s revenue and employment.

Cyberattack Allegations and PDVSA’s Response

On Monday, PDVSA reported that it had fallen victim to a cyberattack. The company claimed that its operations remained unaffected, attributing the attack to foreign interests colluding with “apatrid” factors aiming to undermine Venezuela’s sovereign energy development rights. PDVSA stated that their personnel successfully repelled the attack.

However, sources within PDVSA revealed that a ransomware attack had been detected days prior. The antivirus software used to address the issue reportedly affected all administrative systems, causing disruptions.

Understanding Ransomware Attacks

Ransomware attacks involve malicious software that encrypts a victim’s files or locks their computer. Attackers may also steal data and threaten to leak it. These cyberattacks often occur through phishing, malicious downloads, or infected websites and can cause severe disruptions.

US Department of State’s Response

The US Department of State did not immediately respond to a request for comment on the alleged cyberattack against PDVSA.

Impact on PDVSA Operations

Despite PDVSA’s claims of recovery, industry sources reported that the cyberattack’s effects persisted on Monday. They stated that there was no dispatch of cargoes, and the entire system remained down.

Although production, refining, and internal petroleum distribution were unaffected, PDVSA’s administrative systems could not be restarted on Monday. This forced employees to manually record operations in books.

Additionally, PDVSA ordered administrative and operational staff to disconnect from company systems and limited access for indirect employees to industry facilities.

Impact on Venezuelan Oil Exports

A transporter involved in Venezuelan oil transactions confirmed that all cargo loading instructions for the export market remained suspended.

The seizure of a tanker last week, the first of its kind carrying Venezuelan oil, has led to a significant drop in Venezuela’s oil exports. Among the few tankers still leaving are those chartered by US-based Chevron, a PDVSA partner, operating under a previously granted authorization from Washington.

Venezuela’s crude oil production averaged 1.17 million barrels per day (bpd) last month, according to official figures, while oil exports totaled approximately 952,000 bpd, based on shipping data.
