Two new phishing campaigns have been identified targeting remote workers. One campaign impersonates LogMeIn and the other exploits the COVID-19 pandemic to deliver a legitimate remote administration tool that allows attackers to take full control of a user’s device.
LogMeIn Spoofed to Steal Credentials
Remote workers are being targeted in a phishing campaign that spoofs LogMeIn, a popular cloud-based connectivity service used for remote IT management and collaboration. The emails claim a new update has been released for LogMeIn, with the messages appearing to have been sent by the legitimate LogMeIn Auto-Mailer. The emails include the LogMeIn logo and claim a new security update has been released to fix a new zero-day vulnerability that affects LogMeIn Central and LogMeIn Pro.
A link is supplied in the email that appears to direct the recipient to the accounts.logme.in website and a warning is provided to add urgency to get the user to take immediate action. The email threatens subscription of the service will be suspended if the update is not applied.
The anchor text used in the email masks the true site where the user will be directed. If clicked, the user will be directed to a convincing spoofed LogMeIn URL where credentials are harvested.
There has been an increase in phishing attacks spoofing remote working tools in recent weeks such as LogMeIn, Microsoft Teams, Zoom, GoToMeeting, and Google Meet. Any request sent by email to update security software or take other urgent actions should be treated as suspicious. Always visit the official website by entering the URL into the address bar or use your standard bookmarks. Never use information provided in the email. If the security update is genuine, you will be advised about it when you login.
NetSupport Remote Administration Tool Used to Take Control of Remote Workers’ Laptops
A large-scale phishing campaign has been detected that uses malicious Excel attachments to deliver a legitimate remote access tool that is used by the attackers to take control of a victim’s computer.
The emails used in this campaign appear to have been sent from the Johns Hopkins Center and claim to provide a daily update on COVID-19 deaths in the United States. The Excel file attached to the email – covid_usa_nyt_8072.xls – displays graph taken from the New York Times detailing COVID-19 cases and when opened the user is encouraged to enable content. The Excel file contains a malicious Excel 4.0 macro that downloads a NetSupport Manager client from a remote website if content is enabled, and the client will be automatically executed.
The NetSupport RAT delivered in this campaign drops additional components, including executable files, a VBScript, and an obfuscated PowerSploit-based PowerShell script. Once installed it will connect with its C2 server, allowing the attacker to send further commands.
Block Phishing Attacks and Malware with SpamTitan and WebTitan Cloud
The key to blocking phishing attacks is to implement layered anti-phishing defenses. SpamTitan serves as an additional layer of protection for email that works in tandem with the security anti-spam measures implemented by Google with G-Suite and Microsoft with Office 365 to provide a greater level of protection, especially against sophisticated attacks and zero-day threats. SpamTitan itself includes multiple layers of security to block threats, including dual anti-virus engines, sandboxing, DMARC, and predictive technologies to identify never-before-seen phishing and malware threats.
WebTitan Cloud serves as an additional layer of protection to protect against the web-based component of phishing attacks, with time-of-click protection to block attempts by employees to visit phishing websites linked in emails and redirects to malicious websites during general web browsing. WebTitan works in tandem with email security solutions to increase protection for employees regardless where they access the internet and allows different policies to be set when they are on and off the network.
