[The Mind\'s Bias] Pretexting Now Tops Phishing in Social Engineering Attacks
The New Verizon DBIR is a treasure trove of data. As we will cover a bit below, Verizon reported that 74% of data breaches Involve the "Human Element," so people are one of the most common factors contributing to successful data breaches. Let\'s drill down a bit more in the social engineering section.
They explained: "Now, who has received an email or a direct message on social media from a friend or family member who desperately needs money? Probably fewer of you. This is social engineering (pretexting specifically) and it takes more skill.
"The most convincing social engineers can get into your head and convince you that someone you love is in danger. They use information they have learned about you and your loved ones to trick you into believing the message is truly from someone you know, and they use this invented scenario to play on your emotions and create a sense of urgency. The DBIR Figure 35 shows that Pretexting is now more prevalent than Phishing in Social Engineering incidents. However, when we look at confirmed breaches, Phishing is still on top."
A social attack known as BEC, or business email compromise, can be quite intricate. In this type of attack, the perpetrator uses existing email communications and information to deceive the recipient into carrying out a seemingly ordinary task, like changing a vendor\'s bank account details. But what makes this attack dangerous is that the new bank account provided belongs to the attacker. As a result, any payments the recipient makes to that account will simply disappear.
BEC Attacks Have Nearly Doubled
It can be difficult to spot these attacks as the attackers do a lot of preparation beforehand. They may create a domain doppelganger that looks almost identical to the real one and modify the signature block to show their own number instead of the legitimate vendor.
Attackers can make many subtle changes to trick their targets, especially if they are receiving many similar legitimate requests. This could be one reason why BEC attacks have nearly doubled across the DBIR entire incident dataset, as shown in Figure 36, and now make up over 50% of incidents in this category.
Financially Motivated External Attackers Double Down on Social Engineering
Timely detection and response is crucial when dealing with social engineering attacks, as well as most other attacks. Figure 38 shows a steady increase in the median cost of BECs since 2018, now averaging around $50,000, emphasizing the significance of quick detection.

Earth Lusca Employs Sophisticated Infrastructure, Varied Tools and Techniques
(published: January 17, 2022)
The Earth Lusca threat group is part of the Winnti cluster. It is one of different Chinese groups that share aspects of their tactics, techniques, and procedures (TTPs) including the use of Winnti malware. Earth Lusca were active throughout 2021 committing both cyberespionage operations against government-connected organizations and financially-motivated intrusions targeting gambling and cryptocurrency-related sectors. For intrusion, the group tries different ways in including: spearphishing, watering hole attacks, and exploiting publicly facing servers. Cobalt Strike is one of the group’s preferred post-exploitation tools. It is followed by the use of the BioPass RAT, the Doraemon backdoor, the FunnySwitch backdoor, ShadowPad, and Winnti. The group employs two separate infrastructure clusters, first one is rented Vultr VPS servers used for command-and-control (C2), second one is compromised web servers used to scan for vulnerabilities, tunnel traffic, and Cobalt Strike C2.
Analyst Comment: Earth Lusca often relies on tried-and-true techniques that can be stopped by security best practices, such as avoiding clicking on suspicious email/website links and or reacting on random banners urging to update important public-facing applications. Don’t be tricked to download Adobe Flash update, it was discontinued at the end of December 2020. Administrators should keep their important public-facing applications (such as Microsoft Exchange and Oracle GlassFish Server) updated.

US 2020 Presidential Apps Riddled with Tracking and Security Flaws
(published: September 17, 2020)
The Vote Joe 2020 application has been found to be potentially leaking personal data about voters. The app is used by the Joe Biden campaign to engage with voters and get supporters to send out promotional text messages. Using TargetSmart, an intelligence service, the app receives their predictions via API endpoint which has been found to be returning additional data. Voter preference and voter prediction could be seen, while voter preference is publically accessible, the information for TargetSmart was not meant to be publicly available. The app also let users from outside of the United States download, allowing for non-US citizens to have access to the data, as there was no email verification. Vote Joe isn’t the only campaign app with security issues, as the Donald Trump application exposed hardcoded secret keys in the APK.
Recommendation: The exposure of Personally Identifiable Information (PII) requires affected individuals to take precautionary measures to protect their identity and their finances. Identity theft services can assist in preventing illicit purchases, or applying for financial services from taking place by actors using stolen data.

German Hospital Attacked, Patient Taken to Another City Dies
(published: September 17, 2020)
A failure in IT systems at Duesseldorf University Hospital in Germany has led to the death of a woman. In an apparent ransomware attack, the hospital’s systems crashed with staff unable to access data. While there was no apparent ransom note, 30 servers at the hospital had been encrypted last week, with a ransom note left on one server addressed to Heinrich Heine University. Duesseldorf police contacted the perpetrators to inform them they had attacked the hospital instead of the university, with the perpetrators providing decryption keys, however patients had to be rerouted to other hospitals and therefore a long time before being treated by doctors.
Recommendation: Educate your employees on the risks of opening attachments from unknown senders. Anti-spam and antivirus applications provided by trusted vendors should also be employed. Emails that are received from unknown senders should be carefully avoided, and attachments from such senders should not be opened. Furthermore, it is important to have a comprehensive and tested backup solution in place, in addition to a business continuity plan for the unfortunate case of ransomware infection.
