Ludhiana In a major embarrassment for the state police and officials of the National Highways Authority of India (NHAI), unidentified accused hacked into a digital sign board installed on the national highway that connects Jalandhar to Delhi on Sunday afternoon.

For over 30 minutes, the board, in Libra village of Khanna, displayed abusive language for Punjab chief minister Capt Amarinder Singh, with intermittent messages of ‘Chahunda-e-Punjab, Kejriwal di Sarkar’ (Punjab wants Kejriwal government). The reference is to Aam Aadmi Party (AAP) national convener Arvind Kejriwal. It was only after some passersby informed the police that matter came to light.

“The digital display is operated through Wi-Fi (internet). Someone broke through internet security firewalls and flashed abusive language for the CM. A technical team of the NHAI is on its way to Khanna from Delhi. The accused will be traced and they will submit a report to us. Our own cyber cell is also at work,” said Rajanparminder Singh, DSP, Khanna.

On a complaint from the NHAI, the Sadar police station in Khanna have registered a first an FIR under Sections 500 (defamation) of the Indian Penal Code (IPC) and Section 67 of the IT Act against unidentified accused.

Windows Finger command abused by phishing to download malware

January 15, 2021/in Computer Security

Windows Finger

Attackers are using the normally harmless Windows Finger command to download and install a malicious backdoor on victims’ devices.

The ‘Finger’ command is a utility that originated in Linux/Unix operating systems that allows a local user to retrieve a list of users on a remote machine or information about a particular remote user. In addition to Linux, Windows includes a finger.exe command that performs the same functionality.

To execute the Finger command, a user would enter finger [user]@[remote_host]. For example, finger [email protected].

In September, we reported that security researchers discovered a way to use Finger as a LoLBin to download malware from a remote computer or exfiltrate data. LolBins are legitimate programs that can help attackers bypass security controls to fetch malware without triggering a security alert on the system.

Finger used in an active malware campaign

This week, security researcher Kirk Sayre found a phishing campaign utilizing the Finger command to download the MineBridge backdoor malware.

FireEye first reported on the MineBridge malware after discovering numerous phishing campaigns targeting South Korean organizations. These phishing emails contain malicious Word documents disguised as job applicant resumes that install the MineBridge malware.

Like the previous MineBridge campaigns seen by FireEye, the one discovered by Sayre also pretends to be a resume from a job applicant, as shown below.

When a victim clicks on the ‘Enabled Editing’ or ‘Enable Content’ buttons, a password protected macro will be executed to download the MineBridge malware and run it.

BleepingComputer was able to bypass the password-protection on the Word macro, which is shown below in its obfuscated form.
