A Minnesota cybersecurity and computer forensics expert whose testimony has featured in thousands of courtroom trials over the past 30 years is facing questions about his credentials and an inquiry from the Federal Bureau of Investigation (FBI). Legal experts say the inquiry could be grounds to reopen a number of adjudicated cases in which the expert's testimony may have been pivotal.
### Summary gitoxide uses SHA-1 hash implementations without any collision detection, leaving it vulnerable to hash collision attacks. ### Details gitoxide uses the `sha1_smol` or `sha1` crate, both of which implement standard SHA-1 without any mitigations for collision attacks. This means that two distinct Git objects with colliding SHA-1 hashes would break the Git object model and integrity checks when used with gitoxide. The SHA-1 function is considered cryptographically insecure. However, in the wake of the SHAttered attacks, this issue was mitigated in Git 2.13.0 in 2017 by using the [sha1collisiondetection](https://github.com/crmarcstevens/sha1collisiondetection) algorithm by default and producing an error when known SHA-1 collisions are detected. Git is in the process of migrating to using SHA-256 for object hashes, but this has not been rolled out widely yet and gitoxide does not support SHA-256 object hashes. ### PoC The following program demonstrates the problem, using the...
Microsoft is warning of several phishing campaigns that are leveraging tax-related themes to deploy malware and steal credentials. "These campaigns notably use redirection methods such as URL shorteners and QR codes contained in malicious attachments and abuse legitimate services like file-hosting services and business profile pages to avoid detection," Microsoft said in a report shared with The
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.

### 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");...
