Massive New Spambot Ensnares 711,000,000 Email Addresses (zdnet.com)
An anonymous reader quotes ZDNet: A huge spambot ensnaring 711 million email accounts has been uncovered. A Paris-based security researcher, who goes by the pseudonymous handle Benkow, discovered an open and accessible web server hosted in the Netherlands, which stores dozens of text files containing a huge batch of email addresses, passwords, and email servers used to send spam. Those credentials are crucial for the spammer's large-scale malware operation to bypass spam filters by sending email through legitimate email servers.
The spambot, dubbed "Onliner," is used to deliver the Ursnif banking malware into inboxes all over the world. To date, it's resulted in more than 100,000 unique infections across the world, Benkow told ZDNet. Troy Hunt, who runs breach notification site Have I Been Pwned, said it was a "mind-boggling amount of data." Hunt, who analyzed the data and details his findings in a blog post, called it the "largest" batch of data to enter the breach notification site in its history... Those credentials, he explained, have been scraped and collated from other data breaches, such as the LinkedIn hack and the Badoo hack, as well also other unknown sources.
The data includes information on 80 million email servers, and it's all used to identify which recipients have Windows computers, so they can be targeted in follow-up emails delivering Windows-specific malware. -
iPhone Bug Allows SMS Spoofing
Trailrunner7 writes "The iPhone SMS app contains a quirky bug that could allow someone to send a user a text message that appears to come from any number that the sender specifies. The researcher who discovered the bug said it could be used by attackers to spoof messages from a bank or credit card company and send the victim to a target site controlled by the attacker. The issue lies in the way iOS implements a section of the SMS message called User Data Header, which has a number of options, one of which allows the user to change the phone number that the text message appears to come from. The advent of mobile banking apps, some of which use SMS messages for out-of-band authentication, makes this kind of attack vector perhaps more worrisome and useful for attackers than it would seem at first blush." -
Ox Bow Lake Formation, As Seen By the Google Earth Time Machine
djl4570 writes with a link to this "excellent study in the gradual change of geographic features as a river meander becomes an ox bow lake when the river current cuts through the meander. The same Google Earth feature can be used to view changes in urban and suburban geography. The historical data is a work in progress. The region I looked at only has images going back to 1993. Other regions will have a different mix and depth of data."
