 Rôle Ai \\ dans la cybersécurité: Black Hat USA 2023 révèle la façon dont les modèles de langue façonnentL'avenir des attaques de phishing et de la défense à Black Hat USA 2023, une session dirigée par une équipe de chercheurs en sécurité, dont Fredrik Heiding, Bruce Schneier, Arun Vishwanath et Jeremy Bernstein, ont dévoilé une expérience intrigante.Ils ont testé de grands modèles de langue (LLM) pour voir comment ils ont fonctionné à la fois dans l'écriture de courriels de phishing convaincants et les détecter.Ceci est le PDF document technique . L'expérience: l'élaboration des e-mails de phishing L'équipe a testé quatre LLM commerciaux, y compris le chatppt de l'Openai \\, Bard de Google \\, Claude \\ de Google et Chatllama, dans des attaques de phishing expérimentales contre les étudiants de Harvard.L'expérience a été conçue pour voir comment la technologie de l'IA pouvait produire des leurres de phishing efficaces. Heriding, chercheur à Harvard, a souligné qu'une telle technologie a déjà eu un impact sur le paysage des menaces en facilitant la création de courriels de phishing.Il a dit: "GPT a changé cela. Vous n'avez pas besoin d'être un orateur anglais natif, vous n'avez pas besoin de faire beaucoup. Vous pouvez entrer une invite rapide avec seulement quelques points de données." L'équipe a envoyé des e-mails de phishing offrant des cartes-cadeaux Starbucks à 112 étudiants, en comparant Chatgpt avec un modèle non AI appelé V-Triad.Les résultats ont montré que l'e-mail V-Triad était le plus efficace, avec un taux de clic de 70%, suivi d'une combinaison V-Triad-Chatgpt à 50%, Chatgpt à 30% et le groupe témoin à 20%. Cependant, dans une autre version du test, Chatgpt a fonctionné beaucoup mieux, avec un taux de clic de près de 50%, tandis que la combinaison V-Triad-Chatgpt a mené avec près de 80%.Heriding a souligné qu'un LLM non formé et à usage général a pu créer rapidement des attaques de phishing très efficaces. Utilisation de LLMS pour la détection de phishing La deuxième partie de l'expérience s'est concentrée sur l'efficacité des LLM pour déterminer l'intention des e-mails suspects.L'équipe a utilisé les e-mails de Starbucks de la première partie de l'expérience et a demandé aux LLM de déterminer l'intention, qu'elle ait été composée par un humain ou une IA, d'identifier tout aspect suspect et d'offrir des conseils sur la façon de répondre. Les résultats étaient à la fois surprenants et encourageants.Les modèles avaient des taux de réussite élevés dans l'identification des e-mails marketing, mais ont eu des difficultés avec l'intention des e-mails de phishing V-Triad et Chatgpt.Ils se sont mieux comportés lorsqu'ils sont chargés d'identifier le contenu suspect, les résultats de Claude \\ étant mis en évidence pour non seulement pour obtenir des résultats élevés dans les tests de détection mais aussi fournir des conseils judicieux pour les utilisateurs. La puissance de phishing de LLMS Dans l'ensemble, Heriding a conclu que les LLMS prêtesété formé sur toutes les données de sécurité.Il a déclaré: "C'est vraiment quelque chose que tout le monde peut utiliser en ce moment. C'est assez puissant." L'expér Tool Threat ChatGPT ChatGPT ★★

CyberheistNews Vol 13 #26 CyberheistNews Vol 13 #26  |   June 27th, 2023 [Eyes Open] The FTC Reveals the Latest Top Five Text Message Scams The U.S. Federal Trade Commission (FTC) has published a data spotlight outlining the most common text message scams. Phony bank fraud prevention alerts were the most common type of text scam last year. "Reports about texts impersonating banks are up nearly tenfold since 2019 with median reported individual losses of $3,000 last year," the report says. These are the top five text scams reported by the FTC: Copycat bank fraud prevention alerts Bogus "gifts" that can cost you Fake package delivery problems Phony job offers Not-really-from-Amazon security alerts "People get a text supposedly from a bank asking them to call a number ASAP about suspicious activity or to reply YES or NO to verify whether a transaction was authorized. If they reply, they\'ll get a call from a phony \'fraud department\' claiming they want to \'help get your money back.\' What they really want to do is make unauthorized transfers. "What\'s more, they may ask for personal information like Social Security numbers, setting people up for possible identity theft." Fake gift card offers took second place, followed by phony package delivery problems. "Scammers understand how our shopping habits have changed and have updated their sleazy tactics accordingly," the FTC says. "People may get a text pretending to be from the U.S. Postal Service, FedEx, or UPS claiming there\'s a problem with a delivery. "The text links to a convincing-looking – but utterly bogus – website that asks for a credit card number to cover a small \'redelivery fee.\'" Scammers also target job seekers with bogus job offers in an attempt to steal their money and personal information. "With workplaces in transition, some scammers are using texts to perpetrate old-school forms of fraud – for example, fake \'mystery shopper\' jobs or bogus money-making offers for driving around with cars wrapped in ads," the report says. "Other texts target people who post their resumes on employment websites. They claim to offer jobs and even send job seekers checks, usually with instructions to send some of the money to a different address for materials, training, or the like. By the time the check bounces, the person\'s money – and the phony \'employer\' – are long gone." Finally, scammers impersonate Amazon and send fake security alerts to trick victims into sending money. "People may get what looks like a message from \'Amazon,\' asking to verify a big-ticket order they didn\'t place," the FTC says.

CyberheistNews Vol 13 #22 CyberheistNews Vol 13 #22  |   May 31st, 2023 [Eye on Fraud] A Closer Look at the Massive 72% Spike in Financial Phishing Attacks With attackers knowing financial fraud-based phishing attacks are best suited for the one industry where the money is, this massive spike in attacks should both surprise you and not surprise you at all. When you want tires, where do you go? Right – to the tire store. Shoes? Yup – shoe store. The most money you can scam from a single attack? That\'s right – the financial services industry, at least according to cybersecurity vendor Armorblox\'s 2023 Email Security Threat Report. According to the report, the financial services industry as a target has increased by 72% over 2022 and was the single largest target of financial fraud attacks, representing 49% of all such attacks. When breaking down the specific types of financial fraud, it doesn\'t get any better for the financial industry: 51% of invoice fraud attacks targeted the financial services industry 42% were payroll fraud attacks 63% were payment fraud To make matters worse, nearly one-quarter (22%) of financial fraud attacks successfully bypassed native email security controls, according to Armorblox. That means one in five email-based attacks made it all the way to the Inbox. The next layer in your defense should be a user that\'s properly educated using security awareness training to easily identify financial fraud and other phishing-based threats, stopping them before they do actual damage.

CyberheistNews Vol 13 #21 CyberheistNews Vol 13 #21  |   May 23rd, 2023 [Double Trouble] 78% of Ransomware Victims Face Multiple Extortions in Scary Trend New data sheds light on how likely your organization will succumb to a ransomware attack, whether you can recover your data, and what\'s inhibiting a proper security posture. You have a solid grasp on what your organization\'s cybersecurity stance does and does not include. But is it enough to stop today\'s ransomware attacks? CyberEdge\'s 2023 Cyberthreat Defense Report provides some insight into just how prominent ransomware attacks are and what\'s keeping orgs from stopping them. According to the report, in 2023: 7% of organizations were victims of a ransomware attack 7% of those paid a ransom 73% were able to recover data Only 21.6% experienced solely the encryption of data and no other form of extortion It\'s this last data point that interests me. Nearly 78% of victim organizations experienced one or more additional forms of extortion. CyberEdge mentions threatening to publicly release data, notifying customers or media, and committing a DDoS attack as examples of additional threats mentioned by respondents. IT decision makers were asked to rate on a scale of 1-5 (5 being the highest) what were the top inhibitors of establishing and maintaining an adequate defense. The top inhibitor (with an average rank of 3.66) was a lack of skilled personnel – we\'ve long known the cybersecurity industry is lacking a proper pool of qualified talent. In second place, with an average ranking of 3.63, is low security awareness among employees – something only addressed by creating a strong security culture with new-school security awareness training at the center of it all.

CyberheistNews Vol 13 #19 CyberheistNews Vol 13 #19  |   May 9th, 2023 [Watch Your Back] New Fake Chrome Update Error Attack Targets Your Users Compromised websites (legitimate sites that have been successfully compromised to support social engineering) are serving visitors fake Google Chrome update error messages. "Google Chrome users who use the browser regularly should be wary of a new attack campaign that distributes malware by posing as a Google Chrome update error message," Trend Micro warns. "The attack campaign has been operational since February 2023 and has a large impact area." The message displayed reads, "UPDATE EXCEPTION. An error occurred in Chrome automatic update. Please install the update package manually later, or wait for the next automatic update." A link is provided at the bottom of the bogus error message that takes the user to what\'s misrepresented as a link that will support a Chrome manual update. In fact the link will download a ZIP file that contains an EXE file. The payload is a cryptojacking Monero miner. A cryptojacker is bad enough since it will drain power and degrade device performance. This one also carries the potential for compromising sensitive information, particularly credentials, and serving as staging for further attacks. This campaign may be more effective for its routine, innocent look. There are no spectacular threats, no promises of instant wealth, just a notice about a failed update. Users can become desensitized to the potential risks bogus messages concerning IT issues carry with them. Informed users are the last line of defense against attacks like these. New school security awareness training can help any organization sustain that line of defense and create a strong security culture.

CyberheistNews Vol 13 #15 CyberheistNews Vol 13 #15  |   April 11th, 2023 [The New Face of Fraud] FTC Sheds Light on AI-Enhanced Family Emergency Scams The Federal Trade Commission is alerting consumers about a next-level, more sophisticated family emergency scam that uses AI which imitates the voice of a "family member in distress." They started out with: "You get a call. There\'s a panicked voice on the line. It\'s your grandson. He says he\'s in deep trouble - he wrecked the car and landed in jail. But you can help by sending money. You take a deep breath and think. You\'ve heard about grandparent scams. But darn, it sounds just like him. How could it be a scam? Voice cloning, that\'s how." "Don\'t Trust The Voice" The FTC explains: "Artificial intelligence is no longer a far-fetched idea out of a sci-fi movie. We\'re living with it, here and now. A scammer could use AI to clone the voice of your loved one. All he needs is a short audio clip of your family member\'s voice - which he could get from content posted online - and a voice-cloning program. When the scammer calls you, he\'ll sound just like your loved one. "So how can you tell if a family member is in trouble or if it\'s a scammer using a cloned voice? Don\'t trust the voice. Call the person who supposedly contacted you and verify the story. Use a phone number you know is theirs. If you can\'t reach your loved one, try to get in touch with them through another family member or their friends." Full text of the alert is at the FTC website.

"A leader tasked with cybersecurity can get ahead of the game by understanding where we are in the story of machine learning (ML) as a hacking tool," Tyson writes. "At present, the most important area of relevance around AI for cybersecurity is content generation. "This is where machine learning is making its greatest strides and it dovetails nicely for hackers with vectors such as phishing and malicious chatbots. The capacity to craft compelling, well-formed text is in the hands of anyone with access to ChatGPT, and that\'s basically anyone with an internet connection." Tyson quotes Conal Gallagher, CIO and CISO at Flexera, as saying that since attackers can now write grammatically correct phishing emails, users will need to pay attention to the circumstances of the emails. "Looking for bad grammar and incorrect spelling is a thing of the past - even pre-ChatGPT phishing emails have been getting more sophisticated," Gallagher said. "We must ask: \'Is the email expected? Is the from address legit? Is the email enticing you to click on a link?\' Security awareness training still has a place to play here." Tyson explains that technical defenses have become very effective, so attackers focus on targeting humans to bypass these measures. "Email and other elements of software infrastructure offer built-in fundamental security that largely guarantees we are not in danger until we ourselves take action," Tyson writes. "This is where we can install a tripwire in our mindsets: we should be hyper aware of what it is we are acting upon when we act upon it. "Not until an employee sends a reply, runs an attachment, or fills in a form is sensitive information at risk. The first ring of defense in our mentality should be: \'Is the content I\'m looking at legit, not just based on its internal aspects, but given the entire context?\' The second ring of defense in our mentality then has to be, \'Wait! I\'m being asked to do something here.\'" New-school security awareness training with simulated phishing tests enables your employees to recognize increasingly sophisticated phishing attacks and builds a strong security culture. Remember: Culture eats strategy for breakfast and is always top-down.

knowbe4.webp 2023-02-28 14:00:00 CyberheistNews Vol 13 #09 [Eye Opener] Should You Click on Unsubscribe? (lien direct) CyberheistNews Vol 13 #09 CyberheistNews Vol 13 #09  |   February 28th, 2023 [Eye Opener] Should You Click on Unsubscribe? By Roger A. Grimes. Some common questions we get are "Should I click on an unwanted email's 'Unsubscribe' link? Will that lead to more or less unwanted email?" The short answer is that, in general, it is OK to click on a legitimate vendor's unsubscribe link. But if you think the email is sketchy or coming from a source you would not want to validate your email address as valid and active, or are unsure, do not take the chance, skip the unsubscribe action. In many countries, legitimate vendors are bound by law to offer (free) unsubscribe functionality and abide by a user's preferences. For example, in the U.S., the 2003 CAN-SPAM Act states that businesses must offer clear instructions on how the recipient can remove themselves from the involved mailing list and that request must be honored within 10 days. Note: Many countries have laws similar to the CAN-SPAM Act, although with privacy protection ranging the privacy spectrum from very little to a lot more protection. The unsubscribe feature does not have to be a URL link, but it does have to be an "internet-based way." The most popular alternative method besides a URL link is an email address to use. In some cases, there are specific instructions you have to follow, such as put "Unsubscribe" in the subject of the email. Other times you are expected to craft your own message. Luckily, most of the time simply sending any email to the listed unsubscribe email address is enough to remove your email address from the mailing list.
