Microsoft today issued updates to plug more than 70 security holes in its Windows operating systems and other software, including one vulnerability that is already being exploited. This month’s Patch Tuesday also includes security fixes for the newly released Windows 11 operating system. Separately, Apple has released updates for iOS and iPadOS to address a flaw that is being actively attacked. Firstly, Apple has released iOS 15.0.2 and iPadOS 15.0.2 to fix a zero-day vulnerability (CVE-2021-30883) that is being leveraged in active attacks targeting iPhone and iPad users. Lawrence Abrams of Bleeping Computer writes that the flaw could be used to steal data or install malware, and that soon after Apple patched the bug security researcher Saar Amar published a technical writeup and proof-of-concept exploit that was derived from reverse engineering Apple’s…

Posted by Sam Heft-Luthy, Product Manager, Privacy & Data Protection Office  What happens to our digital accounts when we stop using them? It’s a question we should all ask ourselves, because when we are no longer keeping tabs on what’s happening with old accounts, they can become targets for cybercrime. In fact, quite a few recent high-profile breaches targeted inactive accounts. The Colonial Pipeline ransomware attack came through an inactive account that didn’t use multifactor authentication, according to a consultant who investigated the incident. And in the case of the recent T-Mobile breach this summer, information from inactive prepaid accounts was accessed through old billing files. Inactive accounts can pose a serious security risk. For Google users, Inactive Account Manager helps with that problem. You can decide when Google should…

Facebook and its sister properties Instagram and WhatsApp are suffering from ongoing, global outages. We don’t yet know why this happened, but the how is clear: Earlier this morning, something inside Facebook caused the company to revoke key digital records that tell computers and other Internet-enabled devices how to find these destinations online. Kentik’s view of the Facebook, Instagram and WhatsApp outage. Doug Madory is director of internet analysis at Kentik, a San Francisco-based network monitoring company. Madory said at approximately 11:39 a.m. ET today (15:39 UTC), someone at Facebook caused an update to be made to the company’s Border Gateway Protocol (BGP) records. BGP is a mechanism by which Internet service providers of the world share information about which providers are responsible for routing Internet traffic to which specific…

The U.S. Federal Communications Commission (FCC) is asking for feedback on new proposed rules to crack down on SIM swapping and number port-out fraud, increasingly prevalent scams in which identity thieves hijack a target’s mobile phone number and use that to wrest control over the victim’s online identity. In a long-overdue notice issued Sept. 30, the FCC said it plans to move quickly on requiring the mobile companies to adopt more secure methods of authenticating customers before redirecting their phone number to a new device or carrier. “We have received numerous complaints from consumers who have suffered significant distress, inconvenience, and financial harm as a result of SIM swapping and port-out fraud,” the FCC wrote. “Because of the serious harms associated with SIM swap fraud, we believe that a speedy…

Posted by Meder Kydyraliev and Kim Lewandowski, Google Open Source Security Team Over the past year we have made a number of investments to strengthen the security of critical open source projects, and recently announced our $10 billion commitment to cybersecurity defense including $100 million to support third-party foundations that manage open source security priorities and help fix vulnerabilities. Today, we are excited to announce our sponsorship for the Secure Open Source (SOS) pilot program run by the Linux Foundation. This program financially rewards developers for enhancing the security of critical open source projects that we all depend on. We are starting with a $1 million investment and plan to expand the scope of the program based on community feedback. Why SOS? SOS rewards a very broad range of improvements…

In February, KrebsOnSecurity wrote about a novel cybercrime service that helped attackers intercept the one-time passwords (OTPs) that many websites require as a second authentication factor in addition to passwords. That service quickly went offline, but new research reveals a number of competitors have since launched bot-based services that make it relatively easy for crooks to phish OTPs from targets. An ad for the OTP interception service/bot “SMSRanger.” Many websites now require users to supply both a password and a numeric code/OTP token sent via text message, or one generated by mobile apps like Authy and Google Authenticator. The idea is that even if the user’s password gets stolen, the attacker still can’t access the user’s account without that second factor — i.e. without access to the victim’s mobile device…

The new $30 AirTag tracking device from Apple has a feature that allows anyone who finds one of these tiny location beacons to scan it with a mobile phone and discover its owner’s phone number if the AirTag has been set to lost mode. But according to new research, this same feature can be abused to redirect the Good Samaritan to an iCloud phishing page — or to any other malicious website. The AirTag’s “Lost Mode” lets users alert Apple when an AirTag is missing. Setting it to Lost Mode generates a unique URL at https://found.apple.com, and allows the user to enter a personal message and contact phone number. Anyone who finds the AirTag and scans it with an Apple or Android phone will immediately see that unique Apple URL…

Posted by Guoli Ma, Sebastian Lekies & Claudio Criscione, Google Vulnerability Management TeamOne year ago, we published the Tsunami security scanner with the goal of detecting high severity, actively exploited vulnerabilities with high confidence. In the last several months, the Tsunami scanner team has been working closely with our vulnerability rewards program, Bug Hunters, to further improve Tsunami's security detection capabilities. Today, we are announcing a new experimental Patch Reward Program for the Tsunami project. Participants in the program will receive patch rewards for providing novel Tsunami detection plugins and web application fingerprints. We hope this program will allow us to quickly extend the detection capabilities of the scanner to better benefit our users and uncover more vulnerabilities in their network infrastructure. For this launch, we will accept two types…

In October 2016, media outlets reported that data collected by some of the world’s most renowned cybersecurity experts had identified frequent and unexplained communications between an email server used by the Trump Organization and Alfa Bank, one of Russia’s largest financial institutions. Those publications set off speculation about a possible secret back-channel of communications, as well as a series of lawsuits and investigations that culminated last week with the indictment of the same former federal cybercrime prosecutor who brought the data to the attention of the FBI five years ago. The first page of Alfa Bank’s 2020 complaint. Since 2018, access to an exhaustive report commissioned by the U.S. Senate Armed Services Committee on data that prompted those experts to seek out the FBI has been limited to a handful…
