Researchers Warn of Flaw Affecting Millions of IoT Devices

IBM’s X-Force Red team has discovered a flaw in the Cinterion’s EHS8 module, a small electronic device embedded in IoT devices that connects to wireless networks and sends and receives data. The module is manufactured by Thales, a French company that designs and builds electrical systems for aerospace markets. However, further testing revealed that five other models in the same product line were also affected (BGS5, EHS5/6/8, PDS5/6/8, ELS61, ELS81, PLS62). The modules store and run Java code, often containing confidential information like passwords, encryption keys, and certificates. The bug is tracked as CVE-2020-15858. If exploited, attackers can potentially access the wealth of confidential data stored by the modules. This may include intellectual property (IP), credentials, passwords, encryption keys, and more. Thales has issued a patch to mitigate this flaw and can be administered by IoT manufacturers in two ways, either by plugging in a USB to run an update via software or by administering an over-the-air (OTA) update.

Transparent Tribe APT targets government, military by infecting USB devices

Transparent Tribe is involved in campaigns against government and military personnel, revealing a new tool designed to infect USB devices and spread to other systems. In the latest campaign, the attack stems via spear-phishing emails wherein fraudulent messages are sent together with malicious Microsoft Office documents containing an embedded macro that deploys the group's main payload, the Crimson Remote Access Trojan (RAT). If a victim enables macros, the custom .NET Trojan launches and performs a variety of functions, including connecting to a C2 server for data exfiltration and remote malware updates, stealing files, capturing screenshots, and compromising microphones and webcams for audio and video surveillance. Transparent Tribe makes use of a new USB attack tool called USBWorm that is made up of two main components, a file stealer for removable drives and a worm feature for jumping to new, vulnerable machines. If a USB drive is connected to an infected PC, a copy of the Trojan is quietly installed on the removable drive. The malware will list all directories on a drive, and then a copy of the Trojan is buried in the root drive directory. The directory attribute is then changed to "hidden," and a fake Windows directory icon is used to lure victims into clicking on and executing the payload when they attempt to access directories.

US govt warns remote workers of ongoing vishing campaign - BleepingComputer

The Federal Bureau of Investigation (FBI) and the Cybersecurity and Infrastructure Security Agency (CISA) issued a joint advisory warning teleworkers of an ongoing vishing campaign targeting entities from multiple US industry sectors. Vishing (also known as voice phishing) is a type of social engineering attack where the attackers impersonate a trusted entity during a voice call to manipulate their targets into revealing sensitive information. In mid-July 2020, cybercriminals started a vishing campaign where they registered domains used for phishing that cloned the targeted companies' internal VPN login pages, sites that were also able to harvest two-factor authentication (2FA) or one-time passwords (OTP). They used regular VoIP numbers to make calls to targeted employees' cell phones and later switched tactics to spoof the numbers of other company employees and offices to make their attacks more credible. Using social engineering, the attackers gained their targets' trust, eventually convincing them to use a maliciously crafted VPN login that required them to enter 2FA or OTP codes. They then used the employee access to conduct further research on victims, and find ways to monetize access.

A Google Drive 'Feature' Could Let Attackers Trick You Into Installing Malware

Google Drive contains an unpatched security flaw that could be exploited by malware attackers to distribute malicious files disguised as legitimate documents or images, enabling bad actors to perform spear-phishing attacks comparatively with a high success rate. The flaw resides in the "manage versions" functionality offered by Google Drive that allows users to upload and manage different versions of a file, as well as in the way its interface provides a new version of the files to the users. Although there's no evidence that this flaw has been exploited in the wild, it could still be used as an attack vector to carry out various phishing attacks.

DarkSide: New targeted ransomware demands million dollar ransoms - BleepingComputer

DarkSide, a new ransomware operation, has begun attacking organizations with customized attacks starting earlier this month. According to the researchers, when performing attacks, DarkSide creates a customized ransomware executable for the specific company they are attacking. When executed, the ransomware will execute a PowerShell command that deletes Shadow Volume Copies on the system so that they cannot be used to restore files. It then proceeds to terminate various databases, office applications, and mail clients to prepare the machine for encryption. Each victim will also have a custom extension created using a custom checksum of the victim's MAC address and each executable is customized to include personalized "Welcome to Dark" ransom note, which will include the amount of data that was stolen, the type of data, and a link to their data on the data leak site. The stolen data is then posted to a data leak site under their control and used as part of the extortion attempt.

Transparent Tribe APT hit 1000+ victims in 27 countries in the last 12 months

The Transparent Tribe APT group is carrying out an ongoing cyberespionage campaign aimed at military and diplomatic targets worldwide. The group upgraded its Crimson RAT by adding a management console and implementing a USB worming capability that allows it to propagate from machines within an infected network. The analysis of the new USBWorm component in Crimson RAT revealed that it works as a downloader, infector, and USB stealer. The infection process begins with cataloging all directories of the victim device, then the malware creates a copy of itself in the drive root directory for each one, using the same directory name. The legitimate directories’ attribute is set to “hidden” while the actual directories are being replaced with a copy of the malware using the same directory name. USBWorm uses an icon that mimics a Windows directory to trick the user into launching the malware when trying to access one of the directories.

Security researcher discloses Safari bug after Apple's delays patch - ZDNet

A security researcher has discovered a bug in the Safari browser that could allow hackers to leak or steal files from users' devices. The bug resides in Safari's implementation of the Web Share API, a new web standard that introduced a cross-browser API for sharing text, links, files, and other content. According to the researcher, Safari (on both iOS and macOS) supports sharing files that are stored on the user's local hard drive which is a big privacy issue as this could lead to situations where malicious web pages might invite users to share an article via email with their friends, but end up secretly siphoning or leaking a file from their device. Apple is yet to patch the issue.

SunCrypt Ransomware sheds light on the Maze ransomware cartel - BleepingComputer

Ransomware named SunCrypt has joined the Maze cartel. Maze threat actors created a cartel of ransomware operations to share information and techniques to help each other extort their victims. According to Malwarehunterteam, this new ransomware family began operating in October 2019 but was not very active. SunCrypt is an independently run ransomware group and shares a two-way communication channel with Maze, as part of the cartel. They also share revenue from the successful operation. The ransomware is currently being distributed as a DLL that, when executed, will encrypt a computer's files. When encrypting files, it will append a hexadecimal hash to the end of each file name. In every folder, a link to the data leak site and a ransom note named YOUR_FILES_ARE_ENCRYPTED[.]HTML that contains a link to the Tor payment site is created. The Tor payment site does not have automated features and simply contains a chat screen where a victim can negotiate a ransom with the threat actors. Every victim encrypted by SunCrypt executable will have the same Tor payment site link.

Medical Data Leaked on GitHub Due to Developer Errors

A Dutch researcher has recently discovered nine separate files of highly sensitive personal health information (PHI) from apps such as Office 365 and Google G Suite from nine separate health organizations. Approximately, 150,000 to 200,000 patient health records were exposed due to developers’ improper configuration of access controls and hard-coded credentials in the storing of the information. Patient data found in the files was from health organizations Xybion, MedPro Billing, Texas Physician House Calls, VirMedica, MaineCare, Waystar, Shields Health Care Group, and AccQData.

DeathStalker cyber-mercenary group targets the financial sector

Security researchers at Kaspersky have discovered a hack-for-hire group dubbed DeathStalker that has been targeting organizations worldwide, mainly law firms and financial entities, since 2012. In recent attacks, DeathStalker mercenaries employed the PowerShell-based implant Powersing that allows the attacker to periodically sends screenshot captures to the C2, and to execute arbitrary PowerShell scripts received from the C2. The attackers used spear-phishing messages with an archive containing a malicious LNK file. Upon clicking the shortcuts, arbitrary code gets executed on the victim’s machine. The malicious code further allows threat actors to install additional tools. DeathStalker leveraged multiple public services including Google+, Imgur, Reddit, ShockChan, Tumblr, Twitter, YouTube, and WordPress as dead drop resolvers. These services provide a way for attackers to store data at a fixed URL through public posts, comments, user profiles, content descriptions, etc. Powersing connects the drop resolvers to retrieve the stored information, decode it, and ultimately convert into an IP address that the malware uses to connect to the real C&C server.

US Warns of Ongoing BeagleBoyz Bank-Theft Operations

US law enforcement and government agencies, including the Cybersecurity and Infrastructure Security Agency (CISA), the Department of the Treasury, the FBI, and the US Cyber Command, have issued a joint technical alert concerning an ongoing campaign by the North Korean government to rob banks through an ATM cash-out scheme. The campaign, dubbed "FASTCash 2.0: North Korea's BeagleBoyz Robbing Banks," is an international operation designed to initiate fraudulent international money orders and ATM cash-outs. The BeagleBoyz is an element of the North Korean government's Reconnaissance General Bureau and has been active since at least 2014. The group conducts well-planned, disciplined, and methodical cyber operations akin to careful espionage activities. In the operation, North Korean operatives seek to gain unauthorized access to networks, point-of-sale systems, and ATMs belonging to their victims.

DDoS extortionists target NZX, Moneygram, Braintree, and other financial services

For the past weeks, a criminal gang has launched DDoS attacks against some of the world's biggest financial service providers and demanded Bitcoin payments as extortion fees to stop their attacks. The group uses names like Armada Collective and Fancy Bear, both borrowed from more famous hacker groups to email companies and warning of an impending DDoS attack against their company unless a ransom is paid in Bitcoin. The group has attacked money transfer service MoneyGram, YesBank India, PayPal, Braintree, and Venmo and New Zealand stock exchange (NZX). According to Akamai, the group launched complex DDoS attacks, peaked at 200 Gb/sec, utilizing ARMS, DNS Flood, GRE Protocol Flood, SNMP Flood, SYN Flood, and WSDiscovery Flood attacks as their main vectors, challenging protection controls. DDoS mitigation providers recommend that companies do not give in to these types of extortion attempts.
