Posted by Oliver Chang, OSS-Fuzz team Since launching in 2016, Google's free OSS-Fuzz code testing service has helped get over 8800 vulnerabilities and 28,000 bugs fixed across 850 projects. Today, we’re happy to announce an expansion of our OSS-Fuzz Rewards Program, plus new features in OSS-Fuzz and our involvement in supporting academic fuzzing research. Refreshed OSS-Fuzz rewards The OSS-Fuzz project's purpose is to support the open source community in adopting fuzz testing, or fuzzing — an automated code testing technique for uncovering bugs in software. In addition to the OSS-Fuzz service, which provides a free platform for continuous fuzzing to critical open source projects, we established an OSS-Fuzz Reward Program in 2017 as part of our wider Patch Rewards Program. We’ve operated this successfully for the past 5 years, and…

On Dec. 23, 2022, KrebsOnSecurity alerted big-three consumer credit reporting bureau Experian that identity thieves had worked out how to bypass its security and access any consumer’s full credit report — armed with nothing more than a person’s name, address, date of birth, and Social Security number. Experian fixed the glitch, but remained silent about the incident for a month. This week, however, Experian acknowledged that the security failure persisted for nearly seven weeks, between Nov. 9, 2022 and Dec. 26, 2022. The tip about the Experian weakness came from Jenya Kushnir, a security researcher living in Ukraine who said he discovered the method being used by identity thieves after spending time on Telegram chat channels dedicated to cybercrime. Normally, Experian’s website will ask a series of multiple-choice questions about one’s…

Denis Emelyantsev, a 36-year-old Russian man accused of running a massive botnet called RSOCKS that stitched malware into millions of devices worldwide, pleaded guilty to two counts of computer crime violations in a California courtroom this week. The plea comes just months after Emelyantsev was extradited from Bulgaria, where he told investigators, “America is looking for me because I have enormous information and they need it.” A copy of the passport for Denis Emelyantsev, a.k.a. Denis Kloster, as posted to his Vkontakte page in 2019. First advertised in the cybercrime underground in 2014, RSOCKS was the web-based storefront for hacked computers that were sold as “proxies” to cybercriminals looking for ways to route their Web traffic through someone else’s device. Customers could pay to rent access to a pool of…

T-Mobile today disclosed a data breach affecting tens of millions of customer accounts, its second major data exposure in as many years. In a filing with federal regulators, T-Mobile said an investigation determined that someone abused its systems to harvest subscriber data tied to approximately 37 million current customer accounts. Image: customink.com In a filing today with the U.S. Securities and Exchange Commission, T-Mobile said a “bad actor” abused an application programming interface (API) to hoover up data on roughly 37 million current postpaid and prepaid customer accounts. The data stolen included customer name, billing address, email, phone number, date of birth, T-Mobile account number, as well as information on the number of customer lines and plan features. APIs are essentially instructions that allow applications to access data and interact…

Most people who operate DDoS-for-hire businesses attempt to hide their true identities and location. Proprietors of these so-called “booter” or “stresser” services — designed to knock websites and users offline — have long operated in a legally murky area of cybercrime law. But until recently, their biggest concern wasn’t avoiding capture or shutdown by the feds: It was minimizing harassment from unhappy customers or victims, and insulating themselves against incessant attacks from competing DDoS-for-hire services. And then there are booter store operators like John Dobbs, a 32-year-old computer science graduate student living in Honolulu, Hawaii. For at least a decade until late last year, Dobbs openly operated IPStresser[.]com, a popular and powerful attack-for-hire service that he registered with the state of Hawaii using his real name and address. Likewise, the…

Posted by Chrome Root Program, Chrome Security Team Note: This post is a follow-up to discussions carried out on the Mozilla “Dev Security Policy” Web PKI public discussion forum Google Group in December 2022. Google Chrome communicated its distrust of TrustCor in the public forum on December 15, 2022. The Chrome Security Team prioritizes the security and privacy of Chrome’s users, and we are unwilling to compromise on these values. Google includes or removes CA certificates within the Chrome Root Store as it deems appropriate for user safety in accordance with our policies. The selection and ongoing inclusion of CA certificates is done to enhance the security of Chrome and promote interoperability. Behavior that attempts to degrade or subvert security and privacy on the web is incompatible with organizations whose…

Posted by Dana Jansens (she/her), Chrome Security Team We are pleased to announce that moving forward, the Chromium project is going to support the use of third-party Rust libraries from C++ in Chromium. To do so, we are now actively pursuing adding a production Rust toolchain to our build system. This will enable us to include Rust code in the Chrome binary within the next year. We’re starting slow and setting clear expectations on what libraries we will consider once we’re ready. In this blog post, we will discuss how we arrived at the decision to support third-party Rust libraries at this time, and not broader usage of Rust in Chromium. Why We Chose to Bring Rust into Chromium Our goal in bringing Rust into Chromium is to provide a…

Microsoft today released updates to fix nearly 100 security flaws in its Windows operating systems and other software. Highlights from the first Patch Tuesday of 2023 include a zero-day vulnerability in Windows, printer software flaws reported by the U.S. National Security Agency, and a critical Microsoft SharePoint Server bug that allows a remote, unauthenticated attacker to make an anonymous connection. At least 11 of the patches released today are rated “Critical” by Microsoft, meaning they could be exploited by malware or malcontents to seize remote control over vulnerable Windows systems with little or no help from users. Of particular concern for organizations running Microsoft SharePoint Server is CVE-2023-21743. This is a critical, security bypass flaw that could allow a remote, unauthenticated attacker to make an anonymous connection to a vulnerable…

Identity thieves have been exploiting a glaring security weakness in the website of Experian, one of the big three consumer credit reporting bureaus. Normally, Experian requires that those seeking a copy of their credit report successfully answer several multiple choice questions about their financial history. But until the end of 2022, Experian’s website allowed anyone to bypass these questions and go straight to the consumer’s report. All that was needed was the person’s name, address, birthday and Social Security number. The vulnerability in Experian’s website was exploitable after one applied to see their credit file via annualcreditreport.com. In December, KrebsOnSecurity heard from Jenya Kushnir, a security researcher living in Ukraine who said he discovered the method being used by identity thieves after spending time on Telegram chat channels dedicated to…

KrebsOnSecurity turns 13 years old today. That’s a crazy long time for an independent media outlet these days, but then again I’m bound to keep doing this as long as they keep letting me. Heck, I’ve been doing this so long I briefly forgot which birthday this was! Thanks to your readership and support, I was able to spend more time in 2022 on some deep, meaty investigative stories — the really satisfying kind with the potential to affect positive change. Some of that work is highlighted in the 2022 Year in Review review below. Until recently, I was fairly active on Twitter, regularly tweeting to more than 350,000 followers about important security news and stories here. For a variety of reasons, I will no longer be sharing these updates…
