Emotet Malware Now Hacks Nearby Wi-Fi Networks to Infect New Victims
Emotet, the notorious trojan behind a number of botnet-driven spam campaigns and ransomware attacks, has found a new attack vector: using already infected devices to identify new victims that are connected to nearby Wi-Fi networks. According to researchers at Binary Defense, the newly discovered Emotet sample leverages a “Wi-Fi spreader” module to scan Wi-Fi networks, and then attempts to infect devices that are connected to them.
The cybersecurity firm said the Wi-Fi spreader has a timestamp of April 16, 2018, indicating the spreading behavior has been running “unnoticed” for close to two years until it was detected for the first time last month. The development marks an escalation of Emotet’s capabilities, as networks in close physical proximity to the original victim are now susceptible to infection.

Amex, Chase Fraud Protection Emails Used as Clever Phishing Lure
A very clever phishing campaign is underway that pretends to be fraud protection emails from American Express and Chase that ask you to confirm if the listed credit card transactions are legitimate. If you have credit cards and commonly use them, you may have received emails in the past asking you to confirm if a particular credit card transaction is valid. These emails will display the name of the vendor, the date of the transaction, and the amount of the transaction. It then asks you to confirm if the attempted charge is legitimate or not.

Intel Patches High-Severity Flaw in Security Engine
The high-severity vulnerability could enable denial of service, privilege escalation and information disclosure. Intel is warning of a high-severity flaw in the firmware of its converged security and management engine (CSME), which if exploited could allow privilege escalation, denial of service and information disclosure. CSME powers Intel’s Active Management System hardware and firmware technology, used for remote out-of-band management in consumer or corporate PCs, Internet of Things (IoT) devices, and workstations. The subsystem of CSME has an improper authentication bug (CVE-2019-14598), which has a CVSS score of 8.2 out of 10.0, making it high severity. A privileged user, with local access, could exploit the flaw to launch an array of attacks, according to Intel.

Loda RAT Grows Up
Over the past several months, Cisco Talos has observed a malware campaign that utilizes websites hosting a new version of Loda, a remote access trojan (RAT) written in AutoIT.
These websites also host malicious documents that begin a multi-stage infection chain which ultimately serves a malicious MSI file. The second stage document exploits CVE-2017-11882 to download and run the MSI file, which contains Loda version 1.1.1.
This campaign appears to be targeting countries in South America and Central America, as well as the U.S.

Apple iCloud Credential Stealing
In August 2019 I found a vulnerability in Apples iOS (CVE-2020-3841) during a Red Team Assessment. We were trying to lure users into entering their credentials in a Wi-Fi Phishing Attack. In this case iOS/Safari (macOS was also affected) helped us with it’s AutoFill features. It turned out to be somewhat buggy, but let’s have a quick look how and why it worked, and how we exploited it.
March Patch Tuesday is Coming – the LDAP Changes will Change Your Life!
Next month Microsoft will be changing the default behaviour for LDAP – Cleartext, unsigned LDAP queries against AD (over port 389) will be disabled by default. You’ll still be able to over-ride that using registry keys or group policy, but the best advice is to configure all LDAP clients to use encrypted, signed LDAPS queries (over port 636).
