Screen Shot 2017-09-01 at 07.19.25.png

Highlighting the cyber-security news from the past week in a 120 sec. read. Starting now.

Stolen Credentials

More than 1,700 login credentials were discovered that could be used for an IoT attack.

Why is this significant?

          • A Pastebin address posted a list of telnet-accessible devices containing login credentials for 8,233 unique IP addresses, 2,174 of which were still running open telnet servers.
          • This release signifies weak IoT security. Of the 8,233 hosts, only 144 were unique and the majority of devices are default passwords and user names are “Admin”.
          • 2 takeaways: 1. It is crucial to change user names from the factory issued default, on anything “Smart”, (routers, televisions, refrigerators, printers, etc.) and be sure to create a unique password with 12 or more characters. 2. Disable remote access and restrickedly enable only when needed.

Locky Campaign

23 million emails have been launched in a new Locky ransomware campaign

Why is this significant?

              • These campaigns are launched to hit as many email inboxes as possible preying on the smaller percent of users that will trigger the ransomware.
        • Researchers claim that this Locky campaign is "one of the largest malware campaigns seen in the latter half of 2017".
        • Locky has been hitting more headlines in recent weeks after it was dormant for some time. The success of this campaign depends only on a small percentage of the 23 million users hit,  to click that will pay the ransomware demand of 0.5 bitcoin/$2300.

Potential Spam Campaign

711 million email accounts prepared to issue a spam campaign via Onliner spambot.

Why is this significant?

          • This spam campaign includes lacing emails with data-stealing malware Ursnif and sending spam mail through legitimate email servers.
          • Credentials that are leveraged are generated from already infected machines with Ursnif , phishing campaigns, data-stealing attacks and a list from other public leaks such as in 2016’s LinkedIn breach.  This is being dubbed by a breach notification site- Have I Been Pwned- as the "largest" batch of data to enter the breach notification site in its history”.   
      • In order to bypass the email filters, the attacker is using a list of SMTP credentials which authenticates the spam mail to be sent out as legitimate email, which is a sneaky way to bypass "spam alerts" increasing the amount of vulnerable users that will click the malicious email.
