Vivo (Telefônica Brasil)Breach50212/2025NA
Rankiteo Explanation :
Attack limited on finance or reputation

Description: Movistar Fined €300,000 for GDPR Violation in Spain On December 22, 2025, Spain’s Data Protection Agency (AEPD) imposed a €300,000 fine on Telefónica Móviles, operating as Movistar, for violating the EU’s General Data Protection Regulation (GDPR). The penalty stems from the unlawful processing of personal data during a mobile phone line transfer, where customer information was mishandled. The AEPD ruled that Movistar failed to comply with GDPR requirements, though the company has one month to appeal the decision. The case highlights ongoing regulatory scrutiny over telecom providers’ data handling practices under EU privacy laws. Full details of the ruling are available in the attached decision (in Spanish).

Vivo (Telefônica Brasil)Breach8546/2025NA
Rankiteo Explanation :
Attack with significant impact with customers data leaks

Description: Cybercriminal Dedale Targets BarcelonaTelefónica, Leaks 1M Peruvian Customer Records BarcelonaTelefónica is probing a cyberattack by the threat actor Dedale, who claims to have accessed 22 million customer records though the breach appears limited in scope. As proof, the attacker leaked a database containing one million records, primarily affecting users in Peru. The compromised data includes multiple entries per customer (e.g., names, ID numbers, addresses), meaning the incident does not equate to 22 million unique individuals being exposed. Telefónica confirmed that Spanish customers remain unaffected, as the breach is tied to its former Peruvian subsidiary. The attack surfaced after HackManac disclosed details on X (formerly Twitter). Notably, Dedale is demanding a $1,500 ransom a fraction of typical extortion demands raising questions about the attacker’s motives. The breach coincides with Telefónica’s recent sale of its bankrupt Peruvian operations to Integra Tec International for €900,000, finalized last month. Investigations are ongoing.

Telefónica has downplayed the incident, stating that the data is old and there was no new breach.

Description

SummaryA command injection vulnerability (CWE-78) has been found to exist in the `wrangler pages deploy` command. The issue occurs because the `--commit-hash` parameter is passed directly to a shell command without proper validation or sanitization, allowing an attacker with control of `--commit-hash` to execute arbitrary commands on the system running Wrangler. Root causeThe commitHash variable, derived from user input via the --commit-hash CLI argument, is interpolated directly into a shell command using template literals (e.g.,  execSync(`git show -s --format=%B ${commitHash}`)). Shell metacharacters are interpreted by the shell, enabling command execution. ImpactThis vulnerability is generally hard to exploit, as it requires --commit-hash to be attacker controlled. The vulnerability primarily affects CI/CD environments where `wrangler pages deploy` is used in automated pipelines and the --commit-hash parameter is populated from external, potentially untrusted sources. An attacker could exploit this to: * Run any shell command. * Exfiltrate environment variables. * Compromise the CI runner to install backdoors or modify build artifacts. Credits Disclosed responsibly by kny4hacker. Mitigation * Wrangler v4 users are requested to upgrade to Wrangler v4.59.1 or higher. * Wrangler v3 users are requested to upgrade to Wrangler v3.114.17 or higher. * Users on Wrangler v2 (EOL) should upgrade to a supported major version.
