Ransomware Attackers Quickly Weaponize PHP Vulnerability With 9.8 Severity Rating

A critical vulnerability in the PHP programming language (CVE-2024-4577) has been exploited by ransomware criminals, leading to the infection of up to 1,800 servers primarily in China with the TellYouThePass ransomware. This vulnerability, which affects PHP when run in CGI mode, allows attackers to execute malicious code on web servers. Ars Technica’s Dan Goodin reports: As of Thursday, Internet scans performed by security firm Censys had detected 1,000 servers infected by a ransomware strain known as TellYouThePass, down from 1,800 detected on Monday. The servers, primarily located in China, no longer display their usual content; instead, many list the site’s file directory, which shows all files have been given a .locked extension, indicating they have been encrypted. An accompanying ransom note demands roughly $6,500 in exchange for the decryption key. The vulnerability, tracked as CVE-2024-4577 and carrying a severity rating of 9.8 out of 10, stems from errors in the way PHP converts Unicode characters into ASCII. A feature built into Windows known as Best Fit allows attackers to use a technique known as argument injection to convert user-supplied input into characters that pass malicious commands to the main PHP application. Exploits allow attackers to bypass CVE-2012-1823, a critical code execution vulnerability patched in PHP in 2012.

CVE-2024-4577 affects PHP only when it runs in a mode known as CGI, in which a web server parses HTTP requests and passes them to a PHP script for processing. Even when PHP isn’t set to CGI mode, however, the vulnerability may still be exploitable when PHP executables such as php.exe and php-cgi.exe are in directories that are accessible by the web server. This configuration is extremely rare, with the exception of the XAMPP platform, which uses it by default. An additional requirement appears to be that the Windows locale — used to personalize the OS to the local language of the user — must be set to either Chinese or Japanese. The critical vulnerability was published on June 6, along with a security patch. Within 24 hours, threat actors were exploiting it to install TellYouThePass, researchers from security firm Imperva reported Monday. The exploits executed code that used the mshta.exe Windows binary to run an HTML application file hosted on an attacker-controlled server. Use of the binary indicated an approach known as living off the land, in which attackers use native OS functionalities and tools in an attempt to blend in with normal, non-malicious activity.

In a post published Friday, Censys researchers said that the exploitation by the TellYouThePass gang started on June 7 and mirrored past incidents that opportunistically mass scan the Internet for vulnerable systems following a high-profile vulnerability and indiscriminately targeting any accessible server. The vast majority of the infected servers have IP addresses geolocated to China, Taiwan, Hong Kong, or Japan, likely stemming from the fact that Chinese and Japanese locales are the only ones confirmed to be vulnerable, Censys researchers said in an email. Since then, the number of infected sites — detected by observing the public-facing HTTP response serving an open directory listing showing the server’s filesystem, along with the distinctive file-naming convention of the ransom note — has fluctuated from a low of 670 on June 8 to a high of 1,800 on Monday. Censys researchers said in an email that they’re not entirely sure what’s causing the changing numbers.

Electricity Bills Forecasted To Climb With Summer Heat

The Energy Information Administration (EIA) expects Americans’ monthly electricity bills to average $173 between June through August, compared to $168 last summer. “The slight bump in costs comes from consumers cranking up their air conditioning more to cope with a warmer season than last year,” writes The Verge’s Justine Calma. “Bills would have jumped higher, if not for lower residential electricity prices helping to balance out some of the increased energy use from air conditioning.” From the report: Some regions are likely to be harder hit by the weather than others. Because of heat and humidity along the Gulf Coast, residents in Southern states typically use the most electricity in the summer to cool their homes. The Pacific Coast, meanwhile, faces the biggest potential percentage increase in retail electricity prices in the nation — a 7 percent jump since last year. Wholesale electricity costs there have risen since 2022, in part because of a heat and drought-induced shortfall in hydroelectricity generation. Households along the Pacific could see their electricity bills go up an average of $11 per month this summer, according to the EIA.

To be sure, the EIA says that weather is “the main source of uncertainty” in its forecasts for folks’ utility bills. If this summer winds up being hotter than expected, households could wind up paying even more. Residential electricity use typically peaks in the summer for most of the US because of air conditioning. Extreme heat can even trigger power outages if demand suddenly rises too sharply. California, the Southwest, the Midwest, Texas, and New England are at “elevated risk” of electricity supply shortages during any extreme weather this summer, according to an assessment (PDF) by the North American Electric Reliability Corporation.

OIN Expands Linux Patent Protection Yet Again (But Not To AI)

Steven Vaughan-Nichols reports via ZDNet: While Linux and open-source software (OSS) are no longer constantly under intellectual property (IP) attacks, the Open Invention Network (OIN) patent consortium still stands guard over its patents. Now, OIN, the largest patent non-aggression community, has expanded its protection once again by updating its Linux System definition. Covering more than just Linux, the Linux System definition also protects adjacent open-source technologies. In the past, protection was expanded to Android, Kubernetes, and OpenStack. The OIN accomplishes this by providing a shared defensive patent pool of over 3 million patents from over 3,900 community members. OIN members include Amazon, Google, Microsoft, and essentially all Linux-based companies.

This latest update extends OIN’s existing patent risk mitigation efforts to cloud-native computing and enterprise software. In the cloud computing realm, OIN has added patent coverage for projects such as Istio, Falco, Argo, Grafana, and Spire. For enterprise computing, packages such as Apache Atlas and Apache Solr — used for data management and search at scale, respectively — are now protected. The update also enhances patent protection for the Internet of Things (IoT), networking, and automotive technologies. OpenThread and packages such as agl-compositor and kukusa.val have been added to the Linux System definition. In the embedded systems space, OIN has supplemented its coverage of technologies like OpenEmbedded by adding the OpenAMP and Matter, the home IoT standard. OIN has included open hardware development tools such as Edalize, cocotb, Amaranth, and Migen, building upon its existing coverage of hardware design tools like Verilator and FuseSoc.

Keith Bergelt, OIN’s CEO, emphasized the importance of this update, stating, “Linux and other open-source software projects continue to accelerate the pace of innovation across a growing number of industries. By design, periodic expansion of OIN’s Linux System definition enables OIN to keep pace with OSS’s growth.” […] Looking ahead, Bergelt said, “We made this conscious decision not to include AI. It’s so dynamic. We wait until we see what AI programs have significant usage and adoption levels.” This is how the OIN has always worked. The consortium takes its time to ensure it extends its protection to projects that will be around for the long haul. The OIN practices patent non-aggression in core Linux and adjacent open-source technologies by cross-licensing their Linux System patents to one another on a royalty-free basis. When OIN signees are attacked because of their patents, the OIN can spring into action.

A Growing Number of Americans Are Getting Their News From TikTok

According to a new survey from the Pew Research Center, TikTok is the second most popular source of news for Americans after X, “though most TikTok users don’t primarily think of the shortform video app as a news source,” notes The Verge. The survey looked at how Facebook, Instagram, TikTok and X play a role in Americans’ news diets. From the report: Among TikTok users, only 15 percent say keeping up with the news is a major reason they use the app. Still, 35 percent of those surveyed said they wouldn’t have seen the news they get on TikTok elsewhere. And unlike other apps, the news users see on TikTok is just as likely to come from influencers or celebrities as it is from journalists — and it’s far more likely to come from total strangers. (Meanwhile, most Facebook and Instagram users say the news that pops up on their feeds is posted by friends, relatives, or other people they know; on X, users are more likely to see news posted by media outlets or reporters.)

Google’s Privacy Sandbox Accused of Misleading Chrome Browser Users

Richard Speed reports via The Register: Privacy campaigner noyb has filed a GDPR complaint regarding Google’s Privacy Sandbox, alleging that turning on a “Privacy Feature” in the Chrome browser resulted in unwanted tracking by the US megacorp. The Privacy Sandbox API was introduced in 2023 as part of Google’s grand plan to eliminate third-party tracking cookies. Rather than relying on those cookies, website developers can call the API to display ads matched to a user’s interests. In the announcement, Google’s VP of the Privacy Sandbox initiative called it “a significant step on the path towards a fundamentally more private web.”

However, according to noyb, the problem is that although Privacy Sandbox is advertised as an improvement over third-party tracking, that tracking doesn’t go away. Instead, it is done within the browser by Google itself. To comply with the rules, Google needs informed consent from users, which is where issues start. Noyb wrote today: “Google’s internal browser tracking was introduced to users via a pop-up that said ‘turn on ad privacy feature’ after opening the Chrome browser. In the European Union, users are given the choice to either ‘Turn it on’ or to say ‘No thanks,’ so to refuse consent.” Users would be forgiven for thinking that ‘turn on ad privacy feature’ would protect them from tracking. However, what it actually does is turn on first-party tracking.

Max Schrems, honorary chairman of noyb, claimed: “Google has simply lied to its users. People thought they were agreeing to a privacy feature, but were tricked into accepting Google’s first-party ad tracking. “Consent has to be informed, transparent, and fair to be legal. Google has done the exact opposite.” Noyb noted that Google had argued “choosing to click on ‘Turn it on’ would indeed be considered consent to tracking under Article 6(1)(a) of the GDPR.”

Norway Discovers Europe’s Largest Deposit of Rare Earth Metals

Rare Earths Norway has discovered Europe’s largest proven deposit of rare earth elements in the Fen Carbonatite Complex, positioning Norway as a key player in Europe’s effort to reduce reliance on China’s rare earths supply. CNBC reports: Rare Earths Norway said in a June 6 statement that its Fen Carbonatite Complex in the southeast of the country boasts 8.8 million metric tons of total rare earth oxides (TREOs) with a reasonable prospect for economic extraction. Within the TREOs, which are considered vital to the global shift away from fossil fuels, the company says there is an estimated 1.5 million metric tons of magnet-related rare earths which can be used in electric vehicles and wind turbines. The discovery eclipses a massive rare earths deposit found last year in neighboring Sweden.

One of the aims of the Critical Raw Materials Act is to extract at least 10% of the European Union’s annual demand for rare earths by 2030 and Rare Earths Norway says it hopes to contribute to that goal. Rare Earths Norway said the rare earths deposit in Telemark, roughly 210 kilometers (130 miles) southwest of Oslo, is likely to underscore Norway’s position as an integral part of Europe’s rare earth and critical raw material value chain.
