November 2022. Indian hackers targeted Pakistani government entities, including the military, and companies since April 2020. The attacks enabled hackers to infiltrate systems and access computer controls.
June 2022. Hackers targeted Norwegian public institutions with DDoS attacks, disrupting government websites. The Norwegian NSM security authority attributed the attack to pro-Russian hackers.
March 2022. The National Computer Network Emergency Response Technical Team/Coordination Center of China (CNCERT/CC) stated that hackers from the United States targeted Chinese computers to carry out attacks on Russia, Ukraine, and Belarus.
February 2022. A U.N. report claimed that North Korea hackers stole more than $50 million between 2020 and mid-2021 from three cryptocurrency exchanges. The report also added that in 2021 that amount likely increased, as the DPRK launched 7 attacks on cryptocurrency platforms to help fund their nuclear program in the face of a significant sanctions regime.
Criminal perpetrators of DoS attacks often target sites or services hosted on high-profile web servers such as banks or credit card payment gateways. Revenge, blackmail and hacktivism can motivate these attacks.
In cases such as MyDoom and Slowloris, the tools are embedded in malware and launch their attacks without the knowledge of the system owner. Stacheldraht is a classic example of a DDoS tool. It uses a layered structure where the attacker uses a client program to connect to handlers which are compromised systems that issue commands to the zombie agents which in turn facilitate the DDoS attack. Agents are compromised via the handlers by the attacker using automated routines to exploit vulnerabilities in programs that accept remote connections running on the targeted remote hosts. Each handler can control up to a thousand agents.
In December 2010, WikiLeaks came under intense pressure to stop publishing secret U.S. diplomatic cables. Corporations such as Amazon, PayPal, BankAmerica, Swiss bank PostFinance, MasterCard and Visa either stopped working with or froze their customers' donations to WikiLeaks due to political pressures. In response, those behind Operation Payback directed their activities against these companies. Operation Payback launched DDoS attacks against PayPal, PostFinance and the Swedish Prosecution Authority. On December 8, 2010, a coordinated DDoS attack by Operation Payback brought down both the MasterCard and Visa websites. On December 9, 2010, prior to a sustained DDoS attack on the PayPal website that caused a minor slowdown to its service, PayPal announced on its blog that it would release the frozen funds in the account of the Wau Holland Foundation that was raising funds for WikiLeaks, but would not reactivate the account. Regarding the attacks, WikiLeaks spokesman Kristinn Hrafnsson denied any relation to the group and said, "We neither condemn nor applaud these attacks. We believe they are a reflection of public opinion on the actions of the targets." On the same day, a 16-year-old boy was arrested in The Hague, Netherlands, in connection with the distributed denial-of-service attacks against MasterCard and PayPal. The boy was an IRC operator under the nickname of Jeroenz0r.
Hackers created protocol attacks like the Ping of Death to target the resources websites use to protect themselves like firewalls and load balancers. By disabling these tools, hackers may have a straight shot into the server/website they are trying to disable.
A pro-Russian hacking group claimed responsibility Monday for a denial-of-service attack against FBI websites, marking the latest in a series of nuisance attacks launched against a seemingly capricious and global set of targets.
In the current, connected digital landscape, cybercriminals use sophisticated tools to launch cyberattacks against enterprises. Their attack targets include personal computers, computer networks, IT infrastructure and IT systems. And some common types of cyberattacks are:
To launch volumetric attacks, the botnet uses HTTP pipelining which allows it to send multiple requests over a single connection, thus increasing its total attack throughput. Furthermore, in an attempt to obfuscate the attack source, the botnet uses open SOCKS proxies to proxy their attack traffic to the target.
Nation-state attackers are behind some of these types of attacks. Others, called hacktivists, might launch these types of attacks as a form of protest against the targeted entity; a secretive decentralized group of internationalist activists known as Anonymous is the most well known of such groups.
The first confirmed victim of this backdoor was cybersecurity firm FireEye, which disclosed on Dec. 8 that it was breached by suspected nation-state hackers. It was soon revealed that SolarWinds attacks affected other organizations, including tech giants Microsoft and VMware, as well as many U.S. government agencies. Investigations showed that the hackers -- believed to be sponsored by the Russian government -- had been infiltrating targeted systems undetected since March 2020.
In response, the regime and its Islamic Revolutionary Guard Corps (IRGC) have harassed and even bombed vessels traveling through the Persian Gulf,7 and downed a U.S. drone in international airspace.8 State-backed hackers have, among other things, increased targeted phishing attemptsa against private industry in the United States and around the world9 and against journalists and activists.10 Tehran also stands accused of launching drone and missile attacks on Saudi oil giant Saudi Aramco.b
Operation Ababil: DDoS Attacks on U.S. BanksOperation Ababil involved a series of DDoS campaigns against the U.S. financial sector beginning in December 2011 and continuing into mid-2013.53 The attacks occurred only intermittently for the first 10 months and then escalated to a near-weekly basis starting in September 2012, targeting 46 banks and financial institutions, according to a U.S. Department of Justice indictment.54
Regardless of what the regime itself decides to do, Iranian hackers not affiliated or only loosely affiliated with the Iranian government have already begun taking the initiative to launch low-level, unsophisticated cyberattacks. Soon after the drone strike, attempted attacks against U.S. federal, state, and local government websites originating from Iranian IP addresses jumped 50 percent, according to website security firm Cloudflare.99 Pro-regime hackers successfully defaced websites belonging to the Federal Depository Library Program,100 the Texas Department of Agriculture,101 and an Alabama veterans organization.102 This type of defacement is very simplistic and therefore likely conducted by pro-regime hacktivists looking for the least secure .gov and other websites to score propaganda victories rather than hackers contracted by the Iranian government to conduct a meaningful cyber operation to damage the United States and its allies.
Ransomware has earned its position as one of the leading global cyber threats by adopting the SaaS business model to create RaaS - Ransomware-as-a-Service. The RaaS model allows any novice hacker to launch ransomware attacks with software developed for ease of use. The incentive for hackers to subscribe to RaaS software is an offer to earn a percentage of each successful ransomware payment.
Anonymous regularly launches cyberattacks in support of its social and political ideals as well as against governments and their resources. In this case, Anonymous has declared cyberwar on Russia and called for hackers around the world to target Russian organisations and government. 2b1af7f3a8
