Cybercrime: The Rise of DDoS Attacks in the Net
The FBI reports that in 2015, DDoS extortion attacks are expanding. Indeed, many businesses are being threatened today with network flood attacks. The malicious actors email a potential victim to warn that their Web site will be annihilated by a flood if they fail to pay a huge sum in ransom. Thus businesses are at an increased risk of being extorted by hackers.
The FBI alerted about this threat in an online bulletin at the Internet Crime Complaint Center. This institution works in conjunction with the FBI and other similar agencies. The warning states as follows: “the victim business receives an e-mail threatening a distributed denial-of-service (DDoS) attack to its website unless it pays a ransom.” In fact, it seems that different groups of attackers or individuals are behind those threats, as the ransoms vary in price and the approach is different. For example, some of the criminal demand the ransom in bitcoin, the new online currency. (It is widely considered that bitcoin is almost impossible to trace). In many cases, the attackers warn that victims that do not pay the ransom will have to pay more if they fail to pay within the time frame given. Web Sites administration receives thus subsequent threatening e-mails. Then the attack may come. An attack typically lasts one to two hours with 30 to 35 gigabytes as the physical limit.
The malware that extorts money for the release of encrypted or locked files (so called “ransomware”) is offered in the net for a rather high price. Sometimes this new wave of ransomware attempts to extort funds prior to any attack taking place.
The DDoS attack are likely to expand to online industries and other targeted sectors, especially those susceptible to suffering financial losses if taken offline, according to FBI alert.
One way to protect themselves from the attacks is to report implementing DDoS mitigation services as a precaution.
