SpyAgent is a new Android malware that uses optical character recognition (OCR) to steal cryptocurrency wallet recovery phrases from screenshots stored on mobile devices, allowing attackers to hijack wallets and steal funds. The malware primarily targets South Korea but poses a growing threat as it expands to other regions and possibly iOS. BleepingComputer reports: A malware operation discovered by McAfee was traced back to at least 280 APKs distributed outside of Google Play using SMS or malicious social media posts. This malware can use OCR to recover cryptocurrency recovery phrases from images stored on an Android device, making it a significant threat. […] Once it infects a new device, SpyAgent begins sending the following sensitive information to its command and control (C2) server:

– Victim’s contact list, likely for distributing the malware via SMS originating from trusted contacts.
– Incoming SMS messages, including those containing one-time passwords (OTPs).
– Images stored on the device to use for OCR scanning.
– Generic device information, likely for optimizing the attacks.

SpyAgent can also receive commands from the C2 to change the sound settings or send SMS messages, likely used to send phishing texts to distribute the malware. McAfee found that the operators of the SpyAgent campaign did not follow proper security practices in configuring their servers, allowing the researchers to gain access to them. Admin panel pages, as well as files and data stolen from victims, were easily accessible, allowing McAfee to confirm that the malware had claimed multiple victims. The stolen images are processed and OCR-scanned on the server side and then organized on the admin panel accordingly to allow easy management and immediate utilization in wallet hijack attacks.

SecurityWeek reports:

A significant backdoor in millions of contactless cards made by China-based Shanghai Fudan Microelectronics Group allows instantaneous cloning of RFID smart cards used to open office doors and hotel rooms around the world.

French security services firm Quarkslab has made an eye-popping discovery… Although the backdoor requires just a few minutes of physical proximity to an affected card to conduct an attack, an attacker in a position to carry out a supply chain attack could execute such attacks instantaneously at scale, researcher Philippe Teuwen explained in a paper.

Zack Whittaker reports via TechCrunch: A cyberattack on Mobile Guardian, a U.K.-based provider of educational device management software, has sparked outages at schools across the world and has left thousands of students unable to access their files. Mobile Guardian acknowledged the cyberattack in a statement on its website, saying it identified “unauthorized access to the iOS and ChromeOS devices enrolled to the Mobile Guardian platform.” The company said the cyberattack “affected users globally,” including in North America, Europe and Singapore, and that the incident resulted in an unspecified portion of its userbase having their devices unenrolled from the platform and “wiped remotely.” “Users are not currently able to log in to the Mobile Guardian Platform and students will experience restricted access on their devices,” the company said.

Mobile device management (MDM) software allows businesses and schools to remotely monitor and manage entire fleets of devices used by employees or students. Singapore’s Ministry of Education, touted as a significant customer of Mobile Guardian on the company’s website since 2020, said in a statement overnight that thousands of its students had devices remotely wiped during the cyberattack. “Based on preliminary checks, about 13,000 students in Singapore from 26 secondary schools had their devices wiped remotely by the perpetrator,” the Singaporean education ministry said in a statement. The ministry said it was removing the Mobile Guardian software from its fleet of student devices, including affected iPads and Chromebooks.

According to new report, password manager Dashlane has seen a 400 percent increase in passkey authentications since the beginning of the year, “with 1 in 5 active Dashlane users now having at least one passkey in their Dashlane vault,” reports The Verge. From the report: Over 100 sites now offer passkey support, though Dashlane says the top 20 most popular apps account for 52 percent of passkey authentications. When split into industry sectors, e-commerce (which includes eBay, Amazon, and Target) made up the largest share of passkey authentications at 42 percent. So-called “sticky apps” — meaning those used on a frequent basis, such as social media, e-commerce, and finance or payment sites — saw the fastest passkey adoption between April and June of this year.

Other domains show surprising growth, though — while Roblox is the only gaming category entry within the top 20 apps, its passkey adoption is outperforming giant platforms like Facebook, X, and Adobe, for example. Dashlane’s report also found that passkey usage increased successful sign-ins by 70 percent compared to traditional passwords.

In an incident report today, DigiCert says it discovered that some CNAME-based validations did not include the required underscore prefix, affecting about 0.4% of their domain validations. According to CA/Browser Forum (CABF) rules, certificates with validation issues must be revoked within 24 hours, prompting DigiCert to take immediate action. DigiCert says impacted customers “have been notified.” New submitter jdastrup first shared the news, writing: Due to a mistake going back years that has recently been discovered, DigiCert is required by the CABF to revoke any certificate that used the improper Domain Control Validation (DCV) CNAME record in 24 hours. This could literally be thousands of SSL certs. This could take a lot of time and potentially cause outages worldwide starting July 30 at 19:30 UTC. Be prepared for a long night of cert renewals. DigiCert support line is completely jammed.

In a blog post on Tuesday, security firm KnowBe4 revealed that a remote software engineer hire was a North Korean threat actor using a stolen identity and AI-augmented images. “Detailing a seemingly thorough interview process that included background checks, verified references and four video conference-based interviews, KnowBe4 founder and CEO Stu Sjouwerman said the worker avoided being caught by using a valid identity that was stolen from a U.S.-based individual,” reports CyberScoop. “The scheme was further enhanced by the actor using a stock image augmented by artificial intelligence.” From the report: An internal investigation started when KnowBe4’s InfoSec Security Operations Center team detected “a series of suspicious activities” from the new hire. The remote worker was sent an Apple laptop, which was flagged by the company on July 15 when malware was loaded onto the machine. The AI-filtered photo, meanwhile, was flagged by the company’s Endpoint Detection and Response software. Later that evening, the SOC team had “contained” the fake worker’s systems after he stopped responding to outreach. During a roughly 25-minute period, “the attacker performed various actions to manipulate session history files, transfer potentially harmful files, and execute unauthorized software,” Sjouwerman wrote in the post. “He used a [single-board computer] raspberry pi to download the malware.” From there, the company shared its data and findings with the FBI and with Mandiant, the Google-owned cyber firm, and came to the conclusion that the worker was a fictional persona operating from North Korea.

KnowBe4 said the fake employee likely had his workstation connected “to an address that is basically an ‘IT mule laptop farm.'” They’d then use a VPN to work the night shift from where they actually reside — in this case, North Korea “or over the border in China.” That work would take place overnight, making it appear that they’re logged on during normal U.S. business hours. “The scam is that they are actually doing the work, getting paid well, and give a large amount to North Korea to fund their illegal programs,” Sjouwerman wrote. “I don’t have to tell you about the severe risk of this.” Despite the intrusion, Sjouwerman said “no illegal access was gained, and no data was lost, compromised, or exfiltrated on any KnowBe4 systems.” He chalked up the incident to a threat actor that “demonstrated a high level of sophistication in creating a believable cover identity” and identified “weaknesses in the hiring and background check processes.”

According to Bloomberg, hackers have leaked internal documents stolen from Leidos Holdings, one of the largest IT services providers of the U.S. government. Reuters reports: The company recently became aware of the issue and believes the documents were taken during a previously reported breach of a Diligent Corp. system it used, the report said, adding that Leidos is investigating it. The Virginia-based company, which counts the U.S. Department of Defense as its primary customer, used the Diligent system to host information gathered in internal investigations, the report added, citing a filing from June 2023. A spokesperson for Diligent said the issue seems to be related to an incident from 2022, affecting its subsidiary Steele Compliance Solutions. The company notified impacted customers and had taken corrective action to contain the incident in November 2022.

A 2023 red team exercise by the U.S. Cybersecurity and Infrastructure Security Agency (CISA) at an unnamed federal agency exposed critical security failings, including unpatched vulnerabilities, inadequate incident response, and weak credential management, leading to a full domain compromise. According to The Register’s Connor Jones, the agency failed to detect or remediate malicious activity for five months. From the report: According to the agency’s account of the exercise, the red team was able to gain initial access by exploiting an unpatched vulnerability (CVE-2022-21587 – 9.8) in the target agency’s Oracle Solaris enclave, leading to what it said was a full compromise. It’s worth noting that CVE-2022-21587, an unauthenticated remote code execution (RCE) bug carrying a near-maximum 9.8 CVSS rating, was added to CISA’s known exploited vulnerability (KEV) catalog in February 2023. The initial intrusion by CISA’s red team was made on January 25, 2023. “After gaining access, the team promptly informed the organization’s trusted agents of the unpatched device, but the organization took over two weeks to apply the available patch,” CISA’s report reads. “Additionally, the organization did not perform a thorough investigation of the affected servers, which would have turned up IOCs and should have led to a full incident response. About two weeks after the team obtained access, exploit code was released publicly into a popular open source exploitation framework. CISA identified that the vulnerability was exploited by an unknown third party. CISA added this CVE to its Known Exploited Vulnerabilities Catalog on February 2, 2023.” […]

After gaining access to the Solaris enclave, the red team discovered they couldn’t pivot into the Windows part of the network because missing credentials blocked their path, despite enjoying months of access to sensitive web apps and databases. Undeterred, CISA managed to make its way into the Windows network after carrying out phishing attacks on unidentified members of the target agency, one of which was successful. It said real adversaries may have instead used prolonged password-praying attacks rather than phishing at this stage, given that several service accounts were identified as having weak passwords. After gaining that access, the red team injected a persistent RAT and later discovered unsecured admin credentials, which essentially meant it was game over for the agency being assessed. “None of the accessed servers had any noticeable additional protections or network access restrictions despite their sensitivity and critical functions in the network,” CISA said.

CISA described this as a “full domain compromise” that gave the attackers access to tier zero assets — the most highly privileged systems. “The team found a password file left from a previous employee on an open, administrative IT share, which contained plaintext usernames and passwords for several privileged service accounts,” the report reads. “With the harvested Lightweight Directory Access Protocol (LDAP) information, the team identified one of the accounts had system center operations manager (SCOM) administrator privileges and domain administrator privileges for the parent domain. “They identified another account that also had administrative permissions for most servers in the domain. The passwords for both accounts had not been updated in over eight years and were not enrolled in the organization’s identity management (IDM).” From here, the red team realized the victim organization had trust relationships with multiple external FCEB organizations, which CISA’s team then pivoted into using the access they already had.

The team “kerberoasted” one partner organization. Kerberoasting is an attack on the Kerberos authentication protocol typically used in Windows networks to authenticate users and devices. However, it wasn’t able to move laterally with the account due to low privileges, so it instead used those credentials to exploit a second trusted partner organization. Kerberoasting yielded a more privileged account at the second external org, the password for which was crackable. CISA said that due to network ownership, legal agreements, and/or vendor opacity, these kinds of cross-organizational attacks are rarely tested during assessments. However, SILENTSHIELD assessments are able to be carried out following new-ish powers afforded to CISA by the FY21 National Defense Authorization Act (NDAA), the same powers that also allow CISA’s Federal Attack Surface Testing (FAST) pentesting program to operate. It’s crucial that these avenues are able to be explored in such exercises because they’re routes into systems adversaries will have no reservations about exploring in a real-world scenario. For the first five months of the assessment, the target FCEB agency failed to detect or remediate any of the SILENTSHIELD activity, raising concerns over its ability to spot genuine malicious activity. CISA said the findings demonstrated the need for agencies to apply defense-in-depth principles. The cybersecurity agency recommended network segmentation and a Secure-by-Design commitment.

An anonymous reader shares a report: CDK Global, the company that provides management software for nearly 15,000 car dealerships in North America, is down for a second day following a cyberattack, according to a report from Automotive News. The outage has left car dealerships across North America unable to access the internal systems used to track car sales, view customer information, schedule maintenance, and more.

On Wednesday, CDK Global told dealerships that it’s “investigating a cyber incident” and “proactively shut all systems down” while addressing the issue. However, as reported by Automotive News, CDK Global restored its systems shortly after, only to shut them down hours later due to “an additional cyber incident.”

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.
