Microsoft Warns of Cyber Attack on Ukrainian Computer Networks

“If it turns out that Russia is pummeling Ukraine with cyberattacks,” he said, “and if that continues over the period ahead, we will work with our allies on the appropriate response.”

Mr. Sullivan said that the United States had been working with Ukraine to harden its systems and American networks if the string of ransomware and other attacks from Russia accelerates in the United States.

For President Vladimir V. Putin of Russia, Ukraine has often been a testing range for cyberweapons.

An attack on Ukraine’s Central Election Commission during a presidential election in 2014, in which Russia sought unsuccessfully to change the result, proved to be a model for the Russian intelligence agencies; the United States later found that they had infiltrated the servers of the Democratic National Committee in the United States. In 2015, the first of two major attacks on Ukraine’s electric grid shut off the lights for hours in different parts of the country, including in Kyiv, the capital.

And in 2017, businesses and government agencies in Ukraine were hit with destructive software called NotPetya, which exploited holes in a type of tax preparation software that was widely used in the country. The attack shut down swaths of the economy and hit FedEx and the shipping company Maersk as well; American intelligence officials later traced it to Russian actors. That software, at least in its overall design, bears some resemblance to what Microsoft warned of on Saturday.

The new attack would wipe hard drives clean and destroy files. Some defense experts have said such an attack could be a prelude to a ground invasion by Russia. Others think…


Keys to securing your computer network and insurance data

Always a pressing challenge, the security of your insurance business’ computer network is facing an even greater threat given the stubborn persistence of the coronavirus, according to security pros.

The reason:  Hackers sending emails with malicious links are preying on your workers’ coronavirus fears by sending them official-looking emails that pretend to feature new business policies on the coronavirus.

Plus, hackers are also spoofing your workers by emailing them fake COVID-19 announcements from government agencies as well as fake updates on free government financial support during the pandemic.

Inside all those emails:  Innocuous-looking malicious links that once clicked on will auto-download and activate ransomware and other malware on your insurance business’ computer system.

This onslaught of hacking has become so pitched, it triggered an executive order from U.S. President Joe Biden to all U.S. businesses:  Get serious about ransomware protection.

Says Biden:  The order “calls for federal agencies to work more closely with the private sector to share information, strengthen cybersecurity practices, and deploy technologies that increase reliance against cyberattacks. It outlines innovative ways the government will drive to deliver security and software using federal buying power to jumpstart the market and improve the products that all Americans use.”

The upshot:  Insurance companies and brokers need to be knowledgeable about the new surge in computer network security threats and take the necessary steps to protect their systems and data.

To that end, here are the key moves cybersecurity experts say you need to ensure your insurance company’s computer network is protected from the coming storm:

*Secure employees’ remote computers:  With so many more employees working from home these days, your insurance company’s IT department needs to take special care to safeguard the network connections they’re making between home and work.

A good place to start is to require employees to log into your company computer network via a Virtual Private Network VPN, according to the Kaspersky report, “How Covid-19 Changed the Way People Work”.

Essentially, a…


Fake Telegram apps are doing rounds that can hack your computer regardless of antivirus protection

Fake Telegram apps are posing a huge threat to Windows users. It has been reported that the unauthentic version of the messaging app can hack your devices and put your information at risk. The cybersecurity researchers reported that the fake app has the ability to bypass antivirus systems

As per a report by Minerva Labs, fake installers of the Telegram app are being widely circulated on the Internet. It is reportedly being used to distribute Windows-based ‘Purple Fox’ backdoor on compromised systems.

“We found a large number of malicious installers delivering the same ‘Purple Fox’ rootkit version using the same attack chain. It seems like some were delivered via email, while others we assume were downloaded from phishing websites. The beauty of this attack is that every stage is separated into a different file which is useless without the entire file set. This helps the attacker protect his files from AV (antivirus) detection,” the researcher noted in the blog.

Purple Fox was first discovered in 2018. It is apparently one of the most malicious malware that can be planted in a system beyond the reach of security solutions and evade detection. Once it enters the system, it enables the backdoor to spread more rapidly. The security researcher revealed that such threat actors use legitimate software to drop malicious files.

“This time, however, is different. This threat actor was able to leave most parts of the attack under the radar by separating the attack into several small files, most of which had very low detection rates by AV engines, with the final stage leading to Purple Fox rootkit infection,” the researcher said.

It is advisable to download apps for legitimate places such as the Google Play Store or the Apple App Store. The apps carrying suspicious links should be avoided.
