Fraudsters Using GiftGhostBot Botnet to Steal Gift Card Balances

Fraudsters Using GiftGhostBot Botnet to Steal Gift Card Balances

Mar 25, 2017
Gift cards have once again caused quite a headache for retailers, as cyber criminals are using a botnet to break into and steal cash from money-loaded gift cards provided by major retailers around the globe. Dubbed GiftGhostBot , the new botnet specialized in gift card fraud is an advanced persistent bot (APB) that has been spotted in the wild by cyber security firm Distil Networks. GiftGhostBot has been seen attacking almost 1,000 websites worldwide and defrauding legitimate consumers of the money loaded on gift cards since Distil detected the attack late last month. According to the security firm, any website – from luxury retailers, supermarkets to coffee distributors – that allow their customers to buy products with gift cards could be targeted by the botnet. Operators of the GiftGhostBot botnet launch brute-force attacks against retailer's website to check potential gift card account numbers at a rate of about 1.7 Million numbers per hour, and request the balance f

Bad news for gamers! It's once again the time when most of you will get new PlayStations and XBoxes that continue to be among the most popular gifts for Christmas, but possibilities are you'll not be able to log into the online gaming console, just like what happens on every Christmas holidays. On 2014 Christmas holidays, the notorious hacker group Lizard Squad knocked the PlayStation Network and Xbox Live offline for many gamers by launching massive DDoS attacks against the gaming networks. This time a new hacking group, who managed to take down Tumblr this week for almost two hours, has warned gamers of launching another large-scale distributed denial-of-service (DDoS) attack against XBox Live and PlayStation networks. Calling itself R.I.U. Star Patrol , the hacking group, posted a video on YouTube , announcing that they're planning to take down Sony's PSN and Microsoft's Xbox Live on Christmas Day by launching coordinated DDoS attacks.

Making Sense of Operational Technology Attacks: The Past, Present, and Future

Mar 21, 2024Operational Technology / SCADA Security
When you read reports about cyber-attacks affecting operational technology (OT), it's easy to get caught up in the hype and assume every single one is sophisticated. But are OT environments all over the world really besieged by a constant barrage of complex cyber-attacks? Answering that would require breaking down the different types of OT cyber-attacks and then looking back on all the historical attacks to see how those types compare.  The Types of OT Cyber-Attacks Over the past few decades, there has been a growing awareness of the need for improved cybersecurity practices in IT's lesser-known counterpart, OT. In fact, the lines of what constitutes a cyber-attack on OT have never been well defined, and if anything, they have further blurred over time. Therefore, we'd like to begin this post with a discussion around the ways in which cyber-attacks can either target or just simply impact OT, and why it might be important for us to make the distinction going forward.

More Insights On Alleged DDoS Attack Against Liberia Using Mirai Botnet

Nov 05, 2016
On Thursday, we compiled a story based on research published by a British security expert reporting that some cyber criminals are apparently using Mirai Botnet to conduct DDoS attacks against the telecommunication companies in Liberia, a small African country. In his blog post , Kevin Beaumont claimed that a Liberian transit provider confirmed him about the DDoS attack of more than 500 Gbps targeting one undersea cable servicing Internet connectivity for the entire country. Later, some media outlets also confirmed that the DDoS attack caused Internet outage in some parts of the country, citing 'slow Internet' and 'total outage' experienced by some local sources and citizens. "The DDoS is killing our business. We have a challenge with the DDoS. We are hoping someone can stop it. It's killing our revenue. Our business has frequently been targeted" an employee with one Liberian mobile service provider told PC World . Network firm Level 3 confirmed Zack Whittaker

Guess how many devices participated in last Friday's massive DDoS attack against DNS provider Dyn that caused vast internet outage? Just 100,000 devices. I did not miss any zeros. Dyn disclosed on Wednesday that a botnet of an estimated 100,000 internet-connected devices was hijacked to flood its systems with unwanted requests and close down the Internet for millions of users. Dyn executive vice president Scott Hilton has issued a statement , saying all compromised devices have been infected with a notorious Mirai malware that has the ability to take over cameras, DVRs, and routers. "We're still working on analyzing the data but the estimate at the time of this report is up to 100,000 malicious endpoints," Hilton said. "We are able to confirm that a significant volume of attack traffic originated from Mirai-based botnets." Mirai malware scans for Internet of Things (IoT) devices that are still using their default passwords and then enslaves those
