SMS Attack Spreads Emotet, Steals Bank Credentials:

A new Emotet campaign is spread via SMS messages pretending to be from banks and may have ties to the TrickBot trojan.

Attackers are sending SMS messages purporting to be from victims' banks – but once they click on the links in the text messages, they are asked to hand over their banking credentials and download a file that infects their systems with the Emotet malware.

Emotet has continued to evolve since its return in September, including a new, dangerous Wi-Fi hack feature disclosed last week that can let the malware spread like a worm. Now, this most recent campaign delivers the malware via "smishing," a form of phishing that relies on text messages instead of email. While smishing is certainly nothing new, researchers say that the delivery tactic exemplifies Emotet's operators constantly swapping up their approaches to go beyond mere malspam emails – making it hard for defense teams to keep up.

[...] The SMS messages purport to be from local U.S. numbers and impersonate banks, warning users of locked bank accounts. The messages urge victims to click on a link, which redirects them to a domain that's known to distribute Emotet (shabon[.]co). Visually, when victims click on the link they see a customized phishing page that mimics the bank's mobile banking page.

Threatpost has reached out to X-Force researchers regarding how many victims have received the SMS messages, and which banks the messages purport to be associated with.

    Agreed.

    And given that the danger is in following the link and doing what the phishing page there tells you to do, that link could have been sent via SMS, or by email, or be linked to from twitter (obfuscated through a t.co shortening, no less), or on facebook, or simply be a link in any other webpage or even a usenet post. Or be a QR code on a poster. Or an NFC tag claiming to be a free wifi connection. Or even hand-written on a piece of paper.

    So it ain't really an "SMS attack", really.

    I'm pretty sure I never saw /Politicians Fear Envelope Attack/ headlines when the anthrax white powder scares were going around a few years back, so even failstream media can avoid falling for this kind of mistake if they try.

    Yeah, when I saw this in the submissions queue I was expecting to see a description of a specially crafted SMS that would infect the phone or at least cause it to exfiltrate data. This is not an SMS attack. It's is plain old phisihing.

      Yeah, the unicode parser doing a buffer overflow as a thin-albino-female-with-black-glasses-and-fat-caucasian-male-with-long-hair-holding-hands emoji was being composited, and everyone getting rooted.

    "I'm pretty sure I never saw /Politicians Fear Envelope Attack/ headlines when the anthrax white powder scares were going around"

    Yeah but some probably called it a "mail" attack.
