WIPER MALWARE

What Does “Wiper Malware” Do?

The name “wiper” refers to malware whose purpose is to destroy data, causing financial or reputational damage. The purpose of malware is not to steal money or information and sell it to cybercriminals but to destroy itself. The wiper may work slightly differently, but this malware family almost always has the same goals.

The three destinations are files (data), backups stored on the system, and the boot partition of the system. Most cleaners don’t overwrite discs because it will take too long. This will destroy the files randomly. The attack usually ends up attacking system recovery tools to prevent recovery as a potential quick fix.

How To Prevent This Threat?

Networks must be segmented and access to critical data must be restricted to a select few. You also need to back up your files elsewhere. You may already have a firewall set up, but securing your network is a job that may require some support.

As it has been demonstrated during previous wiper attacks, purely defensive measures will not prevent wiper attacks. As intimidating as it sounds, don’t be discouraged – some measures will at least increase your chances of not getting caught by this malware.

Recent News Report Of Wiper Malware Of Ukraine Attacks

On the night of January 13-14, numerous government websites, including the Ministry of Foreign Affairs, the Ministry of Education and Science, and others, were hacked. The sites were not modified, and there was no leakage of personal data, according to preliminary information.

The coordinated cyberattack on Ukrainian government websites, as well as the use of malware known as WhisperGate to wipe data from certain government systems, are part of a larger wave of malicious activity. The goal of this activity is to disrupt the country’s critical infrastructure. The hackers also used a newly discovered Log4j vulnerability to gain access to some infected systems.

Microsoft issued a warning that a malware operation targeting the Ukrainian government, nonprofits, and IT organizations was attributed to a threat known as “DEV-0586.” MBR records (media service information required to access data) on individual servers and user computers were compromised by attackers.

Furthermore, this is true for both Windows and Linux operating systems.” The Ukrainian cyber police, for their part, stated that they were looking into a combination of three intrusions that were likely used to carry out attacks: a supply chain attack aimed at an IT company that manages websites for the Ukrainian government, the October CMS vulnerability, and the Log4j vulnerability.

Windshield wipers are the stuff of security nightmares. This type of malware can wipe almost all sensitive information from discs, resulting in massive amounts of data loss and financial loss. However, while even the most robust safeguards will not provide complete protection against wiper malware, adhering to strong and sound cybersecurity response plans, backup and recovery strategies. Implementation of anti-malware solutions can significantly reduce the chances of your organization becoming a victim.
