2023-12-04 07:10:47 | Arrêt de cybersécurité du mois: Utilisation de l'IA comportementale pour écraser le détournement de la paie Cybersecurity Stop of the Month: Using Behavioral AI to Squash Payroll Diversion (lien direct) |
This blog post is part of a monthly series exploring the ever-evolving tactics of today\'s cybercriminals. Cybersecurity Stop of the Month focuses on the critical first steps in the attack chain – stopping the initial compromise-in the context of email threats. The series is designed to help you understand how to fortify your defenses to protect people and defend data against emerging threats in today\'s dynamic threat landscape. The first three steps of the attack chain: stop the initial compromise. In our previous posts, we have covered these attack types: Supplier compromise EvilProxy SocGholish E-signature phishing QR code phishing Telephone-oriented attack delivery (TOAD) In this installment we examine a payroll diversion threat that Proofpoint detected during a recent threat assessment. We also cover the typical attack sequence of payroll fraud and explain how Proofpoint uses multiple signals to detect and prevent these threats for our customers. Background Business email compromise (BEC) continues to grow in popularity and sophistication. The 2022 FBI Internet Crime Report notes that BEC attacks cost U.S. businesses $2.7 billion last year. The global figure is no doubt much higher. Ransomware victims, in contrast, lost just $34 million. Payroll diversion is a form of BEC. Typically, employees who have direct access to fulfilling payroll-related requests are prime targets. In these attacks, a bad actor pretends to be an employee who needs to update their direct deposit information. The new information is for an account that the bad actor owns. Once the fraudulent request is complete, the lost funds cannot be retrieved by the business. Payroll diversion fraud isn\'t a new form of BEC, but the frequency of this type of attack is on the rise. Proofpoint continues to see this type of threat getting through the defenses of other email security tools. Across all of our October 2023 threat assessments, we found that more than 400 of these threats got past 12 other email security tools. There are a few reasons why it\'s difficult for a lot of email security tools to detect or remediate these threats. The primary reason is because they don\'t usually carry malicious payloads like attachments or URLs. They also tend to be sent from personal email services-like Google, Yahoo and iCloud-and target specific users. Notably, API-based email security tools that scan for threats post-delivery are the most susceptible to not being able to detect or remediate this type of threat. This partly comes down to how they work. In order for them to be effective, they need security and IT teams to manually populate them with a dictionary of possible display names of all employees, which is a very time-consuming effort that is hard to scale. To avoid this, many organizations simply choose to enable display name prevention for their senior executives only. But bad actors behind payroll diversion don\'t just impersonate executives, they target anyone in the organization who can access corporate funds. In our example below, an attacker took advantage of this exact weakness. The scenario Proofpoint detected a payroll diversion attempt where the attacker posed as a non-executive employee. The email was sent to the director of human resources (HR) at a 300-person company in the energy and utilities industry. The company\'s incumbent email security tool delivered the message, and its API-based post-delivery remediation tool failed to detect and retract it. The threat: How did the attack happen? Here is a closer look at how this payroll diversion scam unfolded: 1. The deceptive message: The attacker sent a request to update their direct deposit information from an account that appeared to be a legitimate employee\'s personal email account. The original malicious message delivered to the recipient\'s inbox. 2. Payroll diversion attack sequence: If the recipient had engaged, the attacker\'s goal would have been to convince them to trans | Ransomware Tool Threat | Yahoo | ★★ |

RSAC 2023 was a huge success. We launched our 2023 AT&T Cybersecurity Insights Report, which was met with enthusiasm by the industry and the media. In fact, Will Townsend, writing for Forbes, noted that our report joined other great research by industry peers who are striving to do more than just provide security solutions. “RSAC 2023 could be best characterized by its emphasis on the advantages and disadvantages of AI and numerous published cybersecurity reports designed to raise awareness of threats and subsequent remediation, in addition to cybersecurity platform enhancements. These subjects are a definite departure from the past few RSAC events, which seemed to be zero-trust "me too” conventions. It is a welcome change, given that the emphasis on improving security outcomes benefits everyone.” Read more >> Townsend perfectly captures the AT&T Cybersecurity mission to help business leaders understand both the business and security landscape - and how it’s evolving as technology continues to change the way we work and live. After listening to the challenges organizations are encountering, it’s clear that research and understanding the business landscape are essential parts of a responsible cybersecurity vendor strategy. DDoS versus ransomware – how does edge computing change the equation? I participated in a panel discussion hosted by Channel Futures examining the challenges of securing critical infrastructure. The discussion kicked off with a Gartner prediction, “by 2025, 30% of critical infrastructure organizations will experience a security breach resulting in the halting of operations and/or mission-critical cyber-physical system.,” I spoke about our research findings that indicate a change in perceived attacks: when it comes to edge computing, DDoS is perceived as a greater attack concern than ransomware. “One of the reasons cybercriminals are gravitating to DDoS is it’s cheaper and easier than ransomware.” Read more >> I did a video interview with BankInfoSecurity.com discussing how edge computing and innovative use cases are changing the way we’re dealing with cyber resilience. "Organizations are investing in the edge but they also know that their endpoints are changing," said Lanowitz. "They want to make sure they are futureproofing themselves and going to be dynamic in their cyber resilience. That\'s because the security edge is not linear or a straight line. It\'s a circuitous, often confusing, and an often-changing environment that you will have to live with." Learn more >> Watch the webcast discussing the AT&T Cybersecurity Insights Report findings.

EvilProxy Phishing-As-A-Service With MFA Bypass Emerged In Dark Web
(published: September 5, 2022)
Resecurity researchers analyzed EvilProxy, a phishing kit that uses reverse proxy and cookie injection methods to bypass two-factor authentication (2FA). EvilProxy uses extensive virtual machine checks and browser fingerprinting. If the victim passes the checks, Evilproxy acts as a proxy between the victim and the legitimate site that asks for credentials. EvilProxy is being sold as a service on the dark web. Since early May 2022, Evilproxy enables phishing attacks against customer accounts of major brands such as Apple, Facebook, GoDaddy, GitHub, Google, Dropbox, Instagram, Microsoft, Twitter, Yahoo, Yandex, and others.
Analyst Comment: EvilProxy is a dangerous automation tool that enables more phishing attacks. Additionally, EvilProxy targeting GitHub and npmjs accounts increases risks of follow-up supply-chain attacks. Anomali platform has historic EvilProxy network indicators that can help when investigating incidents affecting 2FA. With 2FA bypass, users need to be aware of phishing risks and pay even more attention to domains that ask for their credentials and 2FA codes.

Ragnar Locker Ransomware Targeting the Energy Sector
(published: September 1, 2022)
Cybereason researchers investigated the Ragnar Locker ransomware that was involved in cyberattack on DESFA, a Greek pipeline company. On August 19, 2022, the Ragnar Locker group listed DESFA on its data leak site. The group has been active since 2019 and it is not the first time it targets critical infrastructure companies with the double-extortion scheme. Their Ragnar Locker ransomware shows the typical abilities of modern ransomware including system information and location collection, deleting shadow copies, identifying processes (antiviruses, backup solutions, IT remote management solutions, and virtual-based software), and encrypting the system with the exception list in mind.
Analyst Comment: Ragnar Locker appears to be an aggressive ransomware group that is not shy attacking critical infrastructure as far as they are not in the Commonwealth of Independent States (Russia and associated countries). Always be on high alert while reading emails, in particular those with attachments, URL redirection, false sense of urgency or poor grammar. Use anti-spam and antivirus protection, and avoid opening email from untrusted or unverified senders. Additionally, it is important to have a comprehensive and teste |

Update: The Phish Goes On - 5 Million Stolen Credentials and Counting
(published: June 16, 2022)
PIXM researchers describe an ongoing, large-scale Facebook phishing campaign. Its primary targets are Facebook Messenger mobile users and an estimated five million users lost their login credentials. The campaign evades Facebook anti-phishing protection by redirecting to a new page at a legitimate service such as amaze.co, famous.co, funnel-preview.com, or glitch.me. In June 2022, the campaign also employed the tactic of displaying legitimate shopping cart content at the final page for about two seconds before displaying the phishing content. The campaign is attributed to Colombian actor BenderCrack (Hackerasueldo) who monetizes displaying affiliate ads.
Analyst Comment: Users should check what domain is asking for login credentials before providing those. Organizations can consider monitoring their employees using Facebook as a Single Sign-On (SSO) Provider.

F5 Labs Investigates MaliBot
(published: June 15, 2022)
F5 Labs researchers describe a novel Android trojan, dubbed MaliBot. Based on re-written SOVA malware code, MaliBot is maintaining its Background Service by setting itself as a launcher. Its code has some unused evasion portions for emulation environment detection and setting the malware as a hidden app. MaliBot spreads via smishing, takes control of the device and monetizes using overlays for certain Italian and Spanish banks, stealing cryptocurrency, and sometimes sending Premium SMS to paid services.
Analyst Comment: Users should be wary of following links in unexpected SMS messages. Try to avoid downloading apps from third-party websites. Be cautious with enabling accessibility options.

Cybersecurity may be different based on a person's viewpoint. One may want to simply protect and secure their social media accounts from hackers, and that would be the definition of what cybersecurity is to them. On the other hand, a small business owner may want to protect and secure credit card information gathered from their point-of-sale registers and that is what they define as cybersecurity.
Despite differences in implementation, at its core, cybersecurity pertains to the mitigation of potential intrusion of unauthorized persons into your system(s). It should encompass all aspects of one’s digital experience--whether you are an individual user or a company.
Your cyber protection needs to cover your online platforms, devices, servers, and even your cloud storage. Any unprotected area of your digital journey can serve as an exploit point for hackers and cyber criminals intent on finding vulnerabilities.
People assume that it is the responsibility of the IT Department to stop any intrusion. That may be true up to a certain point, cybersecurity responsibility rests with everyone, in reality.
Cybersecurity should be everybody’s business.
The cybersecurity landscape is changing. With 68% of businesses saying that their cybersecurity risks have increased, it is no wonder that businesses have been making increased efforts to protect from, and mitigate attacks.
During the height of the pandemic, about 46% of the workforce shifted to working from home. We saw a surge in cybersecurity attacks - for example, RDP brute-force attacks increased by 400% around the same time.
This is why cybersecurity must be and should be everybody’s business. According to the 2019 Cost of Cybercrime Study, cyberattacks often are successful due to employees willingly participating as an internal actors or or employees and affiliates carelessly clicking a link by accident.
Sadly, it is still happening today. Unsuspecting employees can be caught vulnerable and cause a corporate-wide cyberattack by opening a phishing email or bringing risks into the company’s network in a BYOD (Bring Your Own Device) system.
Just a decade ago, Yahoo experienced a series of major data breaches, via a backdoor to their network system established by a hacker (or a group of hackers). Further digital forensic investigation shows the breach started from a phishing email opened by an employee.
Another example was Equifax when it experienced a data breach in 2017 and was liable for fines amounting to $425 million by the Federal Trade Commission (FTC).
Companies continue to double up on their investments in cybersecurity and privacy protection today to ensure that incidents like these do not happen to their own networks. But a network is only as strong as its weakest link. Hackers continue to innovate, making their attacks more and mo |

2020-11-09 12:00:00 | SecTor 2020, Canada\'s Biggest Cybersecurity Event: Day Two (lien direct) |
This blog was written by an independent guest blogger.
Even though SecTor had to be entirely online this year due to our unusual international circumstances, there have been plenty of excellent talks from many experienced cybersecurity professionals. The talks took place over the course of two days, October 21st and 22nd. Last time I covered the talks I attended on day one. Interestingly enough, the talks all had to do with threat detection and analysis. Maybe that’s just what I’m fixated on these days.
The talks I attended on the second day all covered matters businesses must be aware of these days and well into the future. On day two, I learned a lot about how to talk to non-technical executives about security, the unique challenges of cloud security, and the legal implications of cyber threats. Enjoy!
How to Talk to the Board About Cybersecurity
The first talk I attended on the second day was presented by Jeff Costlow, a CISO with nearly 25 years of industry experience. This is the description of the talk from SecTor’s web app:
“With the sudden shift of the global workforce from in-office to remote, IT teams quickly transformed their operations to accommodate the new realities of business — including large-scale adoption of work-from-home technologies, heightened activity on customer-facing networks, and greater use of online services. While these examples of agility allowed business to continue, they also greatly increased the risk of misconfigurations and cyberthreats. Now, it’s looking like they could be here to stay for a while. On top of that, bad actors have wasted no time trying to exploit new vulnerabilities. In the past several weeks, we’ve seen ransomware attacks affect several major organizations. These attacks come on the tail of a surge of attacks across the board brought on during the pandemic, as hackers scanned and took advantage of new workloads, and vulnerable VPN connections and misconfigurations left the gates to the network open.
When attacks like these make headlines, panicked board members have one question for CISOs: how can we be sure that won’t happen to us? Drawing from nearly 25 years of experience in the security industry, Jeff Costlow, CISO at ExtraHop, will share his top strategies for CISOs to lead board-level conversations about risk management amidst the stark new realities of IT.”
When risk enters an organization through devices that the IT department cannot control, securing a network becomes very difficult. Any devices and applications that connect to the network that administrators can’t administrate are considered to be “shadow IT.” This is often a consequence of bring-your-own-device habits, but not always.
Costlow discussed the implications of shadow IT:
“All you have to do is Google or use the search engine of your choice. Search ‘shadow IT horror stories,’ and you will find a ton of these. There is the laptop that runs underneath someone's desk. It turns out it's a business critical piece of software that everyone's using, and it's just running on a laptop under a desk somewhere.
There are also plenty of stories. These are some of my favorites the ones about somebody just wanted to get their job done. And so they started forwarding all their business email to their Google account or their Yahoo account or something like that. Or maybe a personal Dropbox use. One of my favorites is unapproved chat clients. Or an even worse, operating those chat rooms. This is sometimes called ChatOps. We're inside a chat r |
