Cyber News Rundown: Malware Attack Targets 2018 Winter Olympics

The Cyber News Rundown brings you the latest happenings in cybersecurity news weekly. Who am I? I’m Connor Madsen, a Webroot Threat Research Analyst and a guy with a passion for all things security. Any questions? Just ask.

Winter Olympics Disrupted by Malware Attack

The Winter Olympics are in full swing, and cybercriminals seem to be working just as hard as the athletes. Their nefarious minds are focused on distributing malware that targets several internal WiFi and television systems. In addition to a delay during the opening ceremonies, the malware caused major damage to the networks by wiping non-critical network files and using stolen credentials to traverse the networks with ease. With plenty of international information on hand, it’s surprising the attack focused more on destruction over data collection.

Cryptocurrency Scams from Celebrities on Twitter

At least two dozen fake Twitter accounts impersonating celebrities, and others closely tied to cryptocurrencies, have been promising to distribute various currencies to followers. These accounts are all very similar to the real celebrities’ user accounts, barring small spelling changes, and can be found commenting amongst their target’s posts. Although Twitter appears to be working swiftly to remove these types of accounts, more continue to appear.

News Site Offers Compromise to Disabling Ad-Blockers

With the increasing popularity of cryptojacking—the process of using cryptomining scripts on highly-trafficked sites to generate revenue— is now offering a choice to visitors: disable your ad blocker or let them use your CPU for cryptomining. While this new offering may seem unusual, it’s likely to become more prevalent, since many sites depend on ad revenue to remain operational. The logic is that most users would prefer to allow mining scripts to run over being subjected to ads.

Telegram Leaves Zero-Day Bug Unfixed for Months

Researchers discovered a vulnerability within the Telegram messenger client that would allow attackers to send malware by using a specific character to mask the actual file without making any additional changes to it. This method can be used to fully commandeer a system by sending victims a simple downloader over SMS. The downloader deploys a variety of malicious tools onto the system itself. Telegram has since resolved documented issues, which appear to have targeted mainly Russian victims from as long ago as March 2017.

Canadian Telecom Firm Faces Security Flaw

A hacker has contacted Canadian Telecom firm Freedom Mobile to inform them of the security risks that their nearly 350,000 customers could face if a flaw in their system isn’t fixed. The flaw would allow any attacker to use a brute force attack on the account login page to compromise customer information. The hacker doesn’t appear to be acting maliciously, and he has posted proof of his findings, along with a strong recommendation that Freedom Mobile re-examine its security offerings.

One Response to Cyber News Rundown: Malware Attack Targets 2018 Winter Olympics

  1. News Site Offers Compromise to Disabling Ad-Blockers – umm no.. just no.. if you use my CPU then I want a share in what ever you mine.. Last time i checked you did not buy my CPU so you have NO right in using it ever….and maybe if you looked more carefully on what ad’s you allow on your site I wouldn’t block them (out of all the infections I encounter, that came from a website.. the cause was an infected AD) They are getting smarter now too.. we had a client the first time you went to his site it would redirect you to a fake MS support number.. if you go to it again then it goes to the correct website making it harder for end users to realize there is a problem. they chuck it up to a oh i must have clicked the wrong link.. when in fact you clicked the correct one.

    Cryptocurrency Scams from Celebrities on Twitter – if you dumb enough to fall for it then you deserve it.. When it’s to good to be true.. then guess what? it most likely is. Scams are getting more clever everyday.. ALWAYS QUESTION ANYTHING YOU DON’T KNOW…even if you get an email from the “CEO” (that you are friends with) saying they are in trouble and need you to Wire them 65K.. then you ask them directly via a phone call, don’t go though emails as his account can be hacked.

    Winter Olympics Disrupted by Malware Attack – my only response is.. it could be worse. but srsly.. hackers/cyber-criminals aren’t going anywhere. with technology on the rise it will only get worse from here.
