[Heads Up] Bad Actors Use Voice Phishing in Microsoft Teams To Spread MalwareStu Sjouwerman SACP

Threat actors are using voice phishing (vishing) attacks via Microsoft Teams in an attempt to trick victims into installing the DarkGate malware, according to researchers at Trend Micro.

"The attacker used social engineering to manipulate the victim to gain access and control over a computer system," Trend Micro says.

"The victim reported that she first received several thousand emails, after which she received a call via Microsoft Teams from a caller claiming to be an employee of an external supplier. During the call, the victim was instructed to download Microsoft Remote Support application. However, the installation via the Microsoft Store failed.

"The attacker then instructed the victim to download AnyDesk via browser and manipulate the user to enter her credentials to AnyDesk."

Fortunately, this particular attack was thwarted before the attacker caused any damage. However, Trend Micro notes that similar attacks have led to ransomware deployment.

"DarkGate is primarily distributed through phishing emails, malvertising, and SEO poisoning. However, in this case, the attacker leveraged voice phishing (vishing) to lure the victim," the researchers write. "The vishing technique has also been documented by Microsoft, in a case where the attacker utilized QuickAssist to gain access to its target to distribute ransomware."

The researchers add that security awareness training can help employees thwart social engineering attacks, preventing attackers from gaining access in the first place.

"Provide employee training to raise awareness about social engineering tactics, phishing attempts, and the dangers of unsolicited support calls or pop-ups," Trend Micro says. "Well-informed employees are less likely to fall victim to social engineering attacks, strengthening the organization's overall security posture."

No, KnowBe4 Is Not Being Exploited

Some of our customers are reporting "Threat Alerts" from an email security vendor stating hackers have exploited KnowBe4 or KnowBe4 domains to send email threats. This is being sent to their customers and other non-customers who are members of threat intelligence networks.

Sometimes, there is an included link and it references KnowBe4 along with another of their competitors. The wording choice of the alert is poor and misleading. What they are referencing is the fact that attackers sometimes send phishing emails claiming to be from KnowBe4, usually hoping the potential victim clicks on the included malicious link.

The included malicious link (and sending email address) will sometimes include the phrase 'knowbe4.com' somewhere in an attempt to trick the recipient. It's just brand impersonation. It is well understood that not every email is where it claims to be from. In fact, we have built an entire industry around it.

U.S. Justice Department Indicts Fake IT Workers From North Korea

The U.S. Justice Department revealed indictments against 14 North Korean nationals for their involvement in a long-running scheme designed to pose as remote IT professionals.

The operation aimed to circumvent international sanctions. It also included allegations of wire fraud, money laundering, and identity theft.

Unsealed in a St. Louis federal court, the indictment outlines an intricate plot where North Korean operatives leveraged stolen identities and AI-generated credentials to infiltrate U.S.-based companies. The goal: generate funds for the North Korean government.

The scheme, facilitated by North Korean-controlled entities Yanbian Silverstar in China and Volasys Silverstar in Russia, reportedly earned at least $88 million over a six-year period. Prosecutors said the funds were funneled through financial systems in the U.S. and China to benefit North Korea.

Beyond collecting salaries, the alleged fake IT workers are accused of stealing sensitive data, including proprietary source code, and using it as leverage to extort companies for additional payments.

The indictment also details how these operatives were required to meet minimum monthly earnings of $10,000. To evade detection, they employed advanced methods such as deepfake identities, proxy servers, and pseudonymous accounts.

Mobile Phishing Attacks Use New Tactic to Bypass Security Measures

ESET has published its threat report for the second half of 2024, outlining a new social engineering tactic targeting mobile banking users.

Threat actors are using Progressive Web Apps (PWAs) and WebAPKs to bypass mobile security measures, since these files don't require users to grant permissions to install apps from unknown sources.

"The initial phishing messages were delivered through various methods, including SMS, automated voice calls, and social media malvertising," ESET says.

"Victims received messages or calls suggesting the need to update their mobile banking applications or informing them of potential tax refunds. These messages, sent to presumably random numbers, contained links directing victims to phishing websites mimicking legitimate banking sites.

"Malvertising on Facebook and Instagram promoted a fake banking app, falsely claiming that the official app was being decommissioned."

The apps are designed to trick users into entering their banking credentials, and they can also intercept multi-factor authentication codes. "Once installed, the malicious apps ESET researchers analyzed behave like standard mobile banking malware and present fake banking login interfaces, prompting victims to enter their credentials," the researchers write.

"The stolen credentials, including login details, passwords, and two-factor authentication codes, are then transmitted to the attackers' command and control servers, so that the attackers can gain unauthorized access to victims' accounts."

The researchers expect to see an increase in this phishing technique over the coming year, so users should be wary of installing apps linked in unsolicited messages.

"Unlike traditional apps, these malicious PWAs and WebAPKs are essentially phishing websites packaged to look like legitimate applications," ESET says.

"This means that they do not exhibit the typical behaviors or characteristics associated with malware. Their ability to bypass traditional security warnings of a mobile operating system, and total sidestepping of app store vetting processes is particularly concerning.

"Therefore, it is anticipated that more sophisticated and varied phishing campaigns utilizing PWAs and WebAPKs will emerge, unless mobile platforms change their approach towards them."

AI-Powered Investment Scams Surge: How 'Nomani' Steals Money and Data

Cybersecurity researchers are warning about a new breed of investment scam that combines AI-powered video testimonials, social media malvertising, and phishing tactics to steal money and personal data.

Known as Nomani — a play on "no money" — this scam grew by over 335% in H2 2024, with more than 100 new URLs detected daily between May and November, according to ESET's H2 2024 Threat Report.

"The main goal of the fraudsters is to lead victims to phishing websites and forms that harvest their personal information," ESET noted in the report shared with The Hacker News.

Nomani campaigns rely heavily on fraudulent ads across social media, often impersonating legitimate brands and trusted entities. In some cases, scammers target previous victims, using Europol- and INTERPOL-themed lures promising refunds or assistance in recovering stolen funds.

The ads come from stolen legitimate profiles, fake business accounts, and micro-influencers with significant follower counts. ESET highlights that "another large group of accounts frequently spreading Nomani ads are newly created profiles with easy-to-forget names, a handful of followers, and very few posts."

How to Lose a Fortune with Just One Bad Click

Krebs on Security has posted a new item: "Adam Griffin is still in disbelief over how quickly he was robbed of nearly $500,000 in cryptocurrencies. A scammer called using a real Google phone number to warn his Gmail account was being hacked, sent email security alerts directly from google.com, and ultimately seized control over the account by convincing him to click "yes" to a Google prompt on his mobile device."
