Microsoft today released updates to plug nearly 120 security holes in Windows and supported software. Six of the vulnerabilities were publicly detailed already, potentially giving attackers a head start in figuring out how to exploit them in unpatched systems. More concerning, Microsoft warns that one of the flaws fixed this month is “wormable,” meaning no human interaction would be required for an attack to spread from one vulnerable Windows box to another. Nine of the vulnerabilities fixed in this month’s Patch Tuesday received Microsoft’s “critical” rating, meaning malware or miscreants can exploit them to gain remote access to vulnerable Windows systems through no help from the user. By all accounts, the most severe flaw addressed today is CVE-2022-21907, a critical, remote code execution flaw in the “HTTP Protocol Stack.” Microsoft…

Many readers were surprised to learn recently that the popular Norton 360 antivirus suite now ships with a program which lets customers make money mining virtual currency. But Norton 360 isn’t alone in this dubious endeavor: Avira antivirus — which has built a base of 500 million users worldwide largely by making the product free — was recently bought by the same company that owns Norton 360 and is introducing its customers to a service called Avira Crypto. Avira Crypto Founded in 2006, Avira Operations GmbH & Co. KG is a German multinational software company best known for their Avira Free Security (a.k.a. Avira Free Antivirus). In January 2021, Avira was acquired by Tempe, Ariz.-based NortonLifeLock Inc., the same company that now owns Norton 360. In 2017, the identity theft…

Norton 360, one of the most popular antivirus products on the market today, has installed a cryptocurrency mining program on its customers’ computers. Norton’s parent firm says the cloud-based service that activates the program and allows customers to profit from the scheme — in which the company keeps 15 percent of any currencies mined — is “opt-in,” meaning users have to agree to enable it. But many Norton users complain the mining program is difficult to remove, and reactions from longtime customers have ranged from unease and disbelief to, “Dude, where’s my crypto?” Norton 360 is owned by Tempe, Ariz.-based NortonLifeLock Inc. In 2017, the identity theft protection company LifeLock was acquired by Symantec Corp., which was renamed to NortonLifeLock in 2019 (LifeLock is now included in the Norton 360…

KrebsOnSecurity.com celebrates its 12th anniversary today! Maybe “celebrate” is too indelicate a word for a year wracked by the global pandemics of COVID-19 and ransomware. Especially since stories about both have helped to grow the audience here tremendously in 2021. But this site’s birthday also is a welcome opportunity to thank you all for your continued readership and support, which helps keep the content here free to everyone. More than seven million unique visitors came to KrebsOnSecurity.com in 2021, generating some 12 million+ pageviews and leaving almost 8,000 comments. We also now have nearly 50,000 subscribers to our email newsletter, which is still just a text-based (non-HTML) email that goes out each time a new story is published here (~2-3 times a week).

Based on findings in our ongoing investigations, here is our list of product and service updates as of December 17th (CVE-2021-44228 & CVE-2021-45046): Android is not aware of any impact to the Android Platform or Enterprise. At this time, no update is required for this specific vulnerability, but we encourage our customers to ensure that the latest security updates are applied to their devices. Chrome OS  releases and infrastructure are not using versions of Log4j affected by the vulnerability. Chrome…

Posted by James Wetter and Nicky Ringland, Open Source Insights Team  More than 35,000 Java packages, amounting to over 8% of the Maven Central repository (the most significant Java package repository), have been impacted by the recently disclosed log4j vulnerabilities (1, 2), with widespread fallout across the software industry. The vulnerabilities allow an attacker to perform remote code execution by exploiting the insecure JNDI lookups feature exposed by the logging library log4j. This exploitable feature was enabled by default in many versions of the library. This vulnerability has captivated the information security ecosystem since its disclosure on December 9th because of both its severity and widespread impact. As a popular logging tool, log4j is used by tens of thousands of software packages (known as artifacts in the Java ecosystem) and…

Posted by Jonathan Metzman, Google Open Source Security Team The discovery of the Log4Shell vulnerability has set the internet on fire. Similar to shellshock and heartbleed, Log4Shell is just the latest catastrophic vulnerability in software that runs the internet. Our mission as the Google Open Source Security Team is to secure the open source libraries the world depends on, such as Log4j. One of our capabilities in this space is OSS-Fuzz, a free fuzzing service that is used by over 500 critical open source projects and has found more than 7,000 vulnerabilities in its lifetime. We want to empower open source developers to secure their code on their own. Over the next year we will work on better automated detection of non-memory corruption vulnerabilities such as Log4Shell. We have started…

A 24-year-old New York man who bragged about helping to steal more than $20 million worth of cryptocurrency from a technology executive has pleaded guilty to conspiracy to commit wire fraud. Nicholas Truglia was part of a group alleged to have stolen more than $100 million from cryptocurrency investors using fraudulent “SIM swaps,” scams in which identity thieves hijack a target’s mobile phone number and use that to wrest control over the victim’s online identities. Truglia admitted to a New York federal court that he let a friend use his account at crypto-trading platform Binance in 2018 to launder more than $20 million worth of virtual currency stolen from Michael Terpin, a cryptocurrency investor who co-founded the first angel investor group for bitcoin enthusiasts. Following the theft, Terpin filed a…

Microsoft, Adobe, and Google all issued security updates to their products today. The Microsoft patches include six previously disclosed security flaws, and one that is already being actively exploited. But this month’s Patch Tuesday is overshadowed by the “Log4Shell” 0-day exploit in a popular Java library that web server administrators are now racing to find and patch amid widespread exploitation of the flaw. Log4Shell is the name picked for a critical flaw disclosed Dec. 9 in the popular logging library for Java called “log4j,” which is included in a huge number of Java applications. Publicly released exploit code allows an attacker to force a server running a vulnerable log4j library to execute commands, such as downloading malicious software or opening a backdoor connection to the server. According to researchers at…

Posted by Jon Bottarini, Security Program Manager & Lena Katib, Strategic Partnerships Manager The external security researcher community plays an integral role in making the Google Play ecosystem safe and secure. Through this partnership with the community, Google has been able to collaborate with third-party developers to fix thousands of security issues in Android applications before they are exploited and reward security researchers for their hard work and dedication. In order to empower the next generation of Android security researchers, Google has collaborated with industry partners including HackerOne and PayPal to host a number of Android App Hacking Workshops. These workshops are an effort designed to educate security researchers and cybersecurity students of all skill levels on how to find Android application vulnerabilities through a series of hands-on working sessions,…
