Posted by Eduardo Vela, Google Bug Hunters Team Starting today and for the next 3 months (until January 31 2022), we will pay 31,337 USD to security researchers that exploit privilege escalation in our lab environment with a patched vulnerability, and 50,337 USD to those that use a previously unpatched vulnerability, or a new exploit technique. We are constantly investing in the security of the Linux Kernel because much of the internet, and Google—from the devices in our pockets, to the services running on Kubernetes in the cloud—depend on the security of it. We research its vulnerabilities and attacks, as well as study and develop its defenses. But we know that there is more work to do. That’s why we have decided to build on top of our kCTF VRP from…

Virtually all compilers — programs that transform human-readable source code into computer-executable machine code — are vulnerable to an insidious attack in which an adversary can introduce targeted vulnerabilities into any software without being detected, new research released today warns. The vulnerability disclosure was coordinated with multiple organizations, some of whom are now releasing updates to address the security weakness. Researchers with the University of Cambridge discovered a bug that affects most computer code compilers and many software development environments. At issue is a component of the digital text encoding standard Unicode, which allows computers to exchange information regardless of the language used. Unicode currently defines more than 143,000 characters across 154 different language scripts (in addition to many non-script character sets, such as emojis). Specifically, the weakness involves Unicode’s…

In December 2018, bling vendor Signet Jewelers fixed a weakness in their Kay Jewelers and Jared websites that exposed the order information for all of their online customers. This week, Signet subsidiary Zales.com updated its website to remediate a nearly identical customer data exposure. Last week, KrebsOnSecurity heard from a reader who was browsing Zales.com and suddenly found they were looking at someone else’s order information on the website, including their name, billing address, shipping address, phone number, email address, items and total amount purchased, delivery date, tracking link, and the last four digits of the customer’s credit card number. The reader noticed that the link for the order information she’d stumbled on included a lengthy numeric combination that — when altered — would produce yet another customer’s order information.…

Posted by Kevin Yeo and Sarvar Patel, Private Computing Team  At Google, keeping you safe online is our top priority, so we continuously build the most advanced privacy-preserving technologies into our products. Over the past few years, we've utilized innovations in cryptographic research to keep your personal information private by design and secure by default. As part of this, we launched Password Checkup, which protects account credentials by notifying you if an entered username and password are known to have been compromised in a prior data breach. Using cryptographic techniques, Password Checkup can do this without revealing your credentials to anyone, including Google. Today, Password Checkup protects users across many platforms including Android, Chrome and Google Password Manager. Another example is Private Join and Compute, an open source protocol which…

Posted by Dave Kleidermacher, Jesse Seed, Brandon Barbello, Android, Pixel & Tensor security teams With Pixel 6 and Pixel 6 Pro, we’re launching our most secure Pixel phone yet, with 5 years of security updates and the most layers of hardware security. These new Pixel smartphones take a layered security approach, with innovations spanning across the Google Tensor system on a chip (SoC) hardware to new Pixel-first features in the Android operating system, making it the first Pixel phone with Google security from the silicon all the way to the data center. Multiple dedicated security teams have also worked to ensure that Pixel’s security is provable through transparency and external validation. Secure to the Core Google has put user data protection and transparency at the forefront of hardware security with…

Posted by Royal Hansen, Vice President, Security  According to an Opus and Ponemon Institute study, 59% of companies have experienced a data breach caused by one of their vendors or third parties. Outsourcing operations to third-party vendors has become a popular business strategy as it allows organizations to save money and increase operational efficiency. While these are positives for business operations, they do create significant security risks. These vendors have access to critical systems and customer data and so their security posture becomes equally as important. Up until today, organizations of all sizes have had to design and implement their own security baselines for vendors that align with their risk posture. Unfortunately, this creates an impossible situation for vendors and organizations alike as they try to accommodate thousands of different…

U.S. federal investigators today raided the Florida offices of PAX Technology, a Chinese provider of point-of-sale devices used by millions of businesses and retailers globally. KrebsOnSecurity has learned the raid is tied to reports that PAX’s systems may have been involved in cyberattacks on U.S. and E.U. organizations.

Headquartered in Shenzhen, China, PAX Technology Inc. has more than 60 million point-of-sale terminals in use throughout 120 countries. Earlier today, Jacksonville, Fla. based WOKV.com reported that agents with the FBI and Department of Homeland Security (DHS) had raided a local PAX Technology warehouse. In an official statement, investigators told WOKV only that they were executing a court-authorized search at the warehouse as a part of a federal investigation, and that the…

The Conti ransomware affiliate program appears to have altered its business plan recently. Organizations infected with Conti’s malware who refuse to negotiate a ransom payment are added to Conti’s victim shaming blog, where confidential files stolen from victims may be published or sold. But sometime over the past 48 hours, the cybercriminal syndicate updated its victim shaming blog to indicate that it is now selling access to many of the organizations it has hacked. A redacted screenshot of the Conti News victim shaming blog. “We are looking for a buyer to access the network of this organization and sell data from their network,” reads the confusingly worded message inserted into multiple recent victim listings on Conti’s shaming blog. It’s unclear what prompted the changes, or what Conti hopes to gain…

On Wednesday, the St. Louis Post-Dispatch ran a story about how its staff discovered and reported a security vulnerability in a Missouri state education website that exposed the Social Security numbers of 100,000 elementary and secondary teachers. In a press conference this morning, Missouri Gov. Mike Parson (R) said fixing the flaw could cost the state $50 million, and vowed his administration would seek to prosecute and investigate the “hackers” and anyone who aided the publication in its “attempt to embarrass the state and sell headlines for their news outlet.” Missouri Gov. Mike Parson (R), vowing to prosecute the St. Louis Post-Dispatch for reporting a security vulnerability that exposed teacher SSNs. The Post-Dispatch says it discovered the vulnerability in a web application that allowed the public to search teacher certifications…

A recent phishing campaign targeting Coinbase users shows thieves are getting cleverer about phishing one-time passwords (OTPs) needed to complete the login process. It also shows that phishers are attempting to sign up for new Coinbase accounts by the millions as part of an effort to identify email addresses that are already associated with active accounts. A Google-translated version of the now-defunct Coinbase phishing site, coinbase.com.password-reset[.]com Coinbase is the world’s second-largest cryptocurrency exchange, with roughly 68 million users from over 100 countries. The now-defunct phishing domain at issue — coinbase.com.password-reset[.]com — was targeting Italian Coinbase users (the site’s default language was Italian). And it was fairly successful, according to Alex Holden, founder of Milwaukee-based cybersecurity firm Hold Security. Holden’s team managed to peer inside some poorly hidden file directories associated…
