Google Rolling Out Privacy Sandbox Beta on Android 13 Devices

Google Rolling Out Privacy Sandbox Beta on Android 13 Devices

Feb 15, 2023 Privacy / Technology
Google announced on Tuesday that it's officially rolling out  Privacy Sandbox on Android  in beta to eligible mobile devices running Android 13. "The Privacy Sandbox Beta provides new APIs that are designed with privacy at the core, and don't use identifiers that can track your activity across apps and websites," the search and advertising giant  said . "Apps that choose to participate in the Beta can use these APIs to show you relevant ads and measure their effectiveness." Devices that have been selected for the Beta test will have a Privacy Sandbox section within Settings so as to allow users to control their participation as well as view and manage their top interests as determined by the  Topics API  to serve relevant ads. The initial  Topics taxonomy  is set to include somewhere between a few hundred and a few thousand topics,  according to Google , and will be human-curated to exclude sensitive topics. The Beta test is expected to star...

Update Now: Microsoft Releases Patches for 3 Actively Exploited Windows Vulnerabilities

Feb 15, 2023 Patch Tuesday / Software Updates
Microsoft on Tuesday released  security updates  to address 75 flaws spanning its product portfolio, three of which have come under active exploitation in the wild. The updates are in addition to 22 flaws the Windows maker  patched  in its Chromium-based Edge browser over the past month. Of the 75 vulnerabilities, nine are rated Critical and 66 are rated Important in severity. 37 out of 75 bugs are classified as remote code execution (RCE) flaws. The three zero-days of note that have been exploited are as follows - CVE-2023-21715  (CVSS score: 7.3) - Microsoft Office Security Feature Bypass Vulnerability CVE-2023-21823  (CVSS score: 7.8) - Windows Graphics Component Elevation of Privilege Vulnerability CVE-2023-23376  (CVSS score: 7.8) - Windows Common Log File System (CLFS) Driver Elevation of Privilege Vulnerability "The attack itself is carried out locally by a user with authentication to the targeted system," Microsoft said in advisory for...
Massive AdSense Fraud Campaign Uncovered - 10,000+ WordPress Sites Infected

Massive AdSense Fraud Campaign Uncovered - 10,000+ WordPress Sites Infected

Feb 14, 2023 Ad Fraud / Online Security
The threat actors behind the black hat redirect malware campaign have scaled up their campaign to use more than 70 bogus domains mimicking URL shorteners and infect over 10,800 websites. "The main objective is still ad fraud by artificially increasing traffic to pages which contain the AdSense ID which contain Google ads for revenue generation," Sucuri researcher Ben Martin  said  in a report published last week. Details of the malicious activity were  first exposed  by the GoDaddy-owned company in November 2022. The campaign, which is said to have been active since September last year, is orchestrated to redirect visitors to compromised WordPress sites to fake Q&A portals. The goal, it appears, is to increase the authority of spammy sites in search engine results. "It's possible that these bad actors are simply trying to convince Google that real people from different IPs using different browsers are clicking on their search results," Sucuri noted at ...

Python Developers Beware: Clipper Malware Found in 450+ PyPI Packages!

Python Developers Beware: Clipper Malware Found in 450+ PyPI Packages!

Feb 14, 2023 Cryptocurrency / Software Security
Malicious actors have published more than 451 unique Python packages on the official Python Package Index (PyPI) repository in an attempt to infect developer systems with  clipper malware . Software supply chain security company Phylum, which  spotted the libraries , said the ongoing activity is a follow-up to a campaign that was initially disclosed in November 2022. The initial vector entails using  typosquatting  to mimic popular packages such as beautifulsoup, bitcoinlib, cryptofeed, matplotlib, pandas, pytorch, scikit-learn, scrapy, selenium, solana, and tensorflow, among others. "After installation, a malicious JavaScript file is dropped to the system and executed in the background of any web browsing session," Phylum  said  in a report published last year. "When a developer copies a cryptocurrency address, the address is replaced in the clipboard with the attacker's address." This is achieved by creating a Chromium web browser extension in the W...
A CISOs Practical Guide to Storage and Backup Ransomware Resiliency

A CISOs Practical Guide to Storage and Backup Ransomware Resiliency

Feb 14, 2023 Data Safety / Backup Security
One thing is clear. The " business value"  of data continues to grow, making it an organization's primary piece of intellectual property. From a cyber risk perspective, attacks on data are the most prominent threat to organizations.  Regulators, cyber insurance firms, and auditors are paying much closer attention to the integrity, resilience, and recoverability of organization data – as well as the IT infrastructure & systems that store the data. What Impact Does This Have On The Security Of Storage & Backup Systems? Just a few years ago, almost no CISO thought that storage & backups were important. That's no longer the case today.  Ransomware has pushed backup and recovery back onto the IT and corporate agenda. Cybercriminals, such as Conti, Hive and REvil, are  targeting storage and backup  systems, to prevent recovery. Some ransomwares – Locky and Crypto, for example – now bypass production systems altogether, and directly target backups. ...
Chinese Hackers Targeting South American Diplomatic Entities with ShadowPad

Chinese Hackers Targeting South American Diplomatic Entities with ShadowPad

Feb 14, 2023 Cyber Threat Intelligence
Microsoft on Monday attributed a China-based cyber espionage actor to a set of attacks targeting diplomatic entities in South America. The tech giant's Security Intelligence team is tracking the cluster under the emerging moniker  DEV-0147 ,  describing  the activity as an "expansion of the group's data exfiltration operations that traditionally targeted government agencies and think tanks in Asia and Europe." The threat actor is said to use established hacking tools such as ShadowPad to infiltrate targets and maintain persistent access. ShadowPad, also called PoisonPlug, is a  successor  to the  PlugX remote access trojan  and has been widely put to use by Chinese adversarial collectives with links to the Ministry of State Security (MSS) and People's Liberation Army (PLA), per Secureworks. One of the other malicious tools utilized by DEV-0147 is a webpack loader called QuasarLoader , which allows for deploying additional payloads onto the compro...
Massive HTTP DDoS Attack Hits Record High of 71 Million Requests/Second

Massive HTTP DDoS Attack Hits Record High of 71 Million Requests/Second

Feb 14, 2023
Web infrastructure company Cloudflare on Monday disclosed that it thwarted a record-breaking distributed denial-of-service (DDoS) attack that peaked at over 71 million requests per second (RPS). "The majority of attacks peaked in the ballpark of 50-70 million requests per second (RPS) with the largest exceeding 71 million," the company  said , calling it a "hyper-volumetric" DDoS attack. It's also the largest HTTP DDoS attack reported to date, more than 35% higher than the previous 46 million RPS DDoS attack that  Google Cloud mitigated in June 2022 . Cloudflare said the attacks singled out websites secured by its platform and that they emanated from a botnet comprising more than 30,000 IP addresses that belonged to "numerous" cloud providers. Targeted websites included a popular gaming provider, cryptocurrency companies, hosting providers, and cloud computing platforms. HTTP attacks of this kind are designed to send a tsunami of HTTP requests t...
Patch Now: Apple's iOS, iPadOS, macOS, and Safari Under Attack with New Zero-Day Flaw

Patch Now: Apple's iOS, iPadOS, macOS, and Safari Under Attack with New Zero-Day Flaw

Feb 14, 2023 Device Security / Zero Day
Apple on Monday rolled out security updates for  iOS, iPadOS ,  macOS , and  Safari  to address a zero-day flaw that it said has been actively exploited in the wild. Tracked as  CVE-2023-23529 , the issue relates to a type confusion bug in the WebKit browser engine that could be activated when processing maliciously crafted web content, culminating in arbitrary code execution. The iPhone maker said the bug was addressed with improved checks, adding it's "aware of a report that this issue may have been actively exploited." An anonymous researcher has been credited with reporting the flaw. It's not immediately clear as to how the vulnerability is being exploited in real-world attacks, but it's the second actively abused type confusion flaw in WebKit to be patched by Apple after  CVE-2022-42856  in as many months, which was closed in December 2022.  WebKit flaws are also notable for the fact that they impact every third-party web browser that's...
Hackers Create Malicious Dota 2 Game Modes to Secretly Access Players' Systems

Hackers Create Malicious Dota 2 Game Modes to Secretly Access Players' Systems

Feb 13, 2023 Game Hacking / Cyber Threat
An unknown threat actor created malicious game modes for the Dota 2 multiplayer online battle arena (MOBA) video game that could have been exploited to establish backdoor access to players' systems. The modes exploited a  high-severity flaw  in the V8 JavaScript engine tracked as  CVE-2021-38003  (CVSS score: 8.8), which was  exploited as a zero-day  and addressed by Google in October 2021. "Since V8 was not sandboxed in Dota, the exploit on its own allowed for remote code execution against other Dota players," Avast researcher Jan Vojtěšek  said  in a report published last week. Following responsible disclosure to Valve, the game publisher  shipped fixes  on January 12, 2023, by upgrading the version of V8. Game modes are essentially  custom capabilities  that can either augment an existing title or offer completely new gameplay in a manner that deviates from the standard rules. While publishing a custom game mode to th...
