With tax season in full swing, we're seeing scammers flexing their social engineering muscles. Be prepared.
In an address to Congress this month, President Trump claimed he had "brought free speech back to America." But barely two months into his second term, the president has waged an unprecedented attack on the First Amendment rights of journalists, students, universities, government workers, lawyers and judges. This story explores a slew of recent actions by the Trump administration that threaten to undermine all five pillars of the First Amendment to the U.S. Constitution, which guarantees freedoms concerning speech, religion, the media, the right to assembly, and the right to petition the government and seek redress for wrongs.
Cybercriminals are skilled at using public information to their advantage. Knowing how they gather this data can help…
### Impact User control of the first argument of the `addImage` method results in CPU utilization and denial of service. If given the possibility to pass unsanitized image urls to the `addImage` method, a user can provide a harmful data-url that results in high CPU utilization and denial of service. Other affected methods are: `html`, `addSvgAsImage`. Example payload: ```js import { jsPDF } from "jpsdf" const doc = new jsPDF(); const payload = 'data:/charset=scharset=scharset=scharset=scharset=scharset=scharset=scharset=scharset=scharset=scharset=scharset=scharset=scharset=scharset=scharset=scharset=scharset=scharset=scharset=scharset=scharset=scharset=scharset=scharset=scharset=scharset=scharset=s\x00base64,undefined'; const startTime = performance.now() try { doc.addImage(payload, "PNG", 10, 40, 180, 180, undefined, "SLOW"); } catch (err) { const endTime = performance.now() console.log(`Call to doc.addImage took ${endTime - startTime} milliseconds`) } doc.save("a4.pdf");...

View CSAF 1. EXECUTIVE SUMMARY CVSS v4 7.0 ATTENTION: Low Attack Complexity Vendor: Schneider Electric Equipment: EcoStruxure Power Automation System User Interface (EPAS-UI) Vulnerability: Improper Authentication 2. RISK EVALUATION Successful exploitation of this vulnerability could allow an attacker to bypass device authentication, potentially gain access to sensitive information, or execute arbitrary code. 3. TECHNICAL DETAILS 3.1 AFFECTED PRODUCTS Schneider Electric reports that the following products are affected: EcoStruxure Power Automation System User Interface (EPAS-UI): Version v2.1 up to and including v2.9 3.2 VULNERABILITY OVERVIEW 3.2.1 IMPROPER AUTHENTICATION CWE-287 The Schneider Electric EcoStruxure Power Automation System User Interface (EPAS-UI) is vulnerable to authentication bypass. This occurs when an unauthorized user, without permission rights, has physical access to the EPAS-UI computer and is able to reboot the workstation and interrupt the normal boot process....
The FBI has warned about free file converters that are up to no good and can lead to ransomware and identity theft.
A clever malware deployment scheme first spotted in targeted attacks last year has now gone mainstream. In this scam, dubbed "ClickFix," the visitor to a hacked or malicious website is asked to distinguish themselves from bots by pressing a combination of keyboard keys that causes Microsoft Windows to download password-stealing malware.
**Description:** The `secure_redundant_execution` function in feldman_vss.py attempts to mitigate fault injection attacks by executing a function multiple times and comparing results. However, several critical weaknesses exist: 1. Python's execution environment cannot guarantee true isolation between redundant executions 2. The constant-time comparison implementation in Python is subject to timing variations 3. The randomized execution order and timing provide insufficient protection against sophisticated fault attacks 4. The error handling may leak timing information about partial execution results These limitations make the protection ineffective against targeted fault injection attacks, especially from attackers with physical access to the hardware. **Impact:** A successful fault injection attack could allow an attacker to: 1. Bypass the redundancy check mechanisms 2. Extract secret polynomial coefficients during share generation or verification 3. Force the acceptance of inva...
**Description:** The `feldman_vss` library contains timing side-channel vulnerabilities in its matrix operations, specifically within the `_find_secure_pivot` function and potentially other parts of `_secure_matrix_solve`. These vulnerabilities are due to Python's execution model, which does not guarantee constant-time execution. An attacker with the ability to measure the execution time of these functions (e.g., through repeated calls with carefully crafted inputs) could potentially recover secret information used in the Verifiable Secret Sharing (VSS) scheme. The `_find_secure_pivot` function, used during Gaussian elimination in `_secure_matrix_solve`, attempts to find a non-zero pivot element. However, the conditional statement `if matrix[row][col] != 0 and row_random < min_value:` has execution time that depends on the value of `matrix[row][col]`. This timing difference can be exploited by an attacker. The `constant_time_compare` function in this file also does not provide a con...
