Figure 1: Actor "YuriSeb0" posted a link to download the MangaDex data breach package
The breach occurred when threat actors gained unauthorized access to a MangaDex administrator account through "the reuse of a session token found in an old database leak through faulty configuration of session management." Shortly after discovering the incident, MangaDex took the website offline to patch vulnerable code and update the website. MangaDex strongly advises website users to change passwords.
Breach Disclosure: Descomplica
During March 2021, the Brazilian educational tech company, Descomplica, suffered a data breach. The breached data contained just under 5 million email addresses, and associated names, partial credit card information, purchase history, and password hashes.

Threat actors gained access to nearly 9 million records of Jefit user information, including encrypted passwords. Jefit reported that financial data was not included in the data breach, as the company does not store customer payment information. Jefit strongly recommends that all users change their password to a more secure format.
In February 2021, an actor using the alias "N9XDZ" posted a data breach package targeting Jefit on a Russian-speaking cybercriminal marketplace forum. The dataset contains 2.8 million records of de-hashed credentials, specifically email and password pairs, and is circulating in other cybercriminal marketplace forums.

Breach Disclosure: Emotet The FBI and the Dutch NHTCU have released over 4 million email addresses of accounts victimized by the Emotet trojan. According to HIBP, 39% of the victim accounts were already known from previous breaches.
Recommendations
- Enable 2-factor authentication for all of your organizational accounts to help mitigate phishing and credential stuffing attacks.
- If not already enabled, turn on the compromised credentials rule for all relevant entities and ensure relevant emails are entered for those entities, or reach out to [email protected] for assistance.
- If one of your entities receives an alert, ZeroFOX recommends immediate password changes for the affected account.
Details
On 25 April, the FBI, in coordination with the Dutch National High Technical Crimes Unit (NHTCU) released 4,324,770 emails to the Have I Been Pwned (HIBP) data breach notification website. Due to the sensitive nature of the data, HIBP is not listing the accounts in a searchable format, but the site is sending out direct victim notifications. Alternately, if an administrator can provide proof of ownership of a domain they will be able to see if they are impacted via the HIBP notification service or by a domain search.
These accounts were released following a seizure of the botnet’s infrastructure by international law enforcement in eight countries on January 27th, and a measure remotely directing all copies of the malware to uninstall themselves from victim computers, also on April 25.

Hackers Exploit VPN to Deploy SUPERNOVA malware on SolarWinds Orion
The U.S. Cybersecurity and Infrastructure Security Agency (CISA) has disclosed details of a new advanced persistent threat (APT) that's leveraging the Supernova backdoor to compromise SolarWinds Orion installations after gaining access to the network through a connection to a Pulse Secure VPN device. Interestingly, the adversary is said to have used valid accounts that had multi-factor authentication (MFA) enabled, rather than an exploit for a vulnerability, to connect to the VPN, thus allowing them to masquerade as legitimate teleworking employees of the affected entity. An investigation into the incident is ongoing. In the meantime, CISA is recommending organizations to implement MFA for privileged accounts, enable firewalls to filter unsolicited connection requests, enforce strong password policies, and secure Remote Desktop Protocol (RDP) and other remote access solutions.

Boffins found a bug in Apple AirDrop that could leak users’ personal info
Security researchers have discovered a privacy issue in Apple’s wireless file-sharing protocol Apple AirDrop that could expose user’s contact information, such as email addresses and phone numbers. The experts pointed out that an attacker could learn the phone numbers and email addresses of AirDrop users, even if it is not direct contact. The attackers need to have a Wi-Fi-capable device and physical proximity to a target that initiates the discovery process by opening the sharing pane on an iOS or macOS device.

Microsoft Edge to add automatic HTTPS option for all domains - BleepingComputer
Microsoft Edge will automatically redirect users to a secure HTTPS connection when visiting websites using the HTTP protocol, starting with version 92, coming in late July. By default, this new option will allow Edge users to switch from HTTP to HTTPS on websites that are likely to support the more secure protocol. However, users will also be able to configure the browser to upgrade all connections to HTTPS (Hypertext Transfer Protocol Secure) as the default internet communication protocol for all domains.

Minnesota University Apologizes for Contributing Malicious Code to the Linux Project
Researchers from the University of Minnesota apologized to the maintainers of the Linux Kernel Project on Saturday for intentionally including vulnerabilities in the project's code, which led to the school being banned from contributing to the open-source project in the future. The apology comes over a study into what's called "hypocrite commits," which was published earlier this February. The project aimed to deliberately add use-after-free vulnerabilities to the Linux kernel in the name of security research, apparently in an attempt to highlight how potentially malicious code could sneak past the approval process, and as a consequence, suggest ways to improve the security of the patching process.
