According to a report from blockchain analysis company Chainalysis (USA), hackers globally have appropriated about $ 1.3 billion in ransom from attack victims in the past 2 years.

According to an analysis published on February 10, Chainalysis saw a significant increase in ransom payments, with $602 million in 2021 and $692 million in 2020. This has reflected a sharp increase in cybercrime over the years and has driven push global efforts to prevent it.

According to the report, the amount of ransom that cybercriminals have appropriated in 2021 is expected to increase and surpass 2020 when new information is updated.

Meanwhile, Chainalysis data shows that in 2018 and 2019 the ransom payments were only $39 million and $152 million, respectively.

According to cybersecurity experts, the victims of hackers often do not disclose information about the attacks or the amount of cryptocurrency ransom they have spent. Secrecy is one reason that cybercrime groups often based in Russia and Eastern Europe continue to target businesses in the US.

The average total payout in an attack is more than $118,000 in 2021, the report said, up from $88,000 in 2020 and $25,000 in 2019.

The US, UK and Australia issued a joint alert on February 8 to warn of the growing global threat from ransomware. The hackers have adopted advanced techniques, such as professionalizing business models and sharing data about potential victims, officials said.

The Biden administration has launched a series of initiatives to strengthen cybersecurity defenses, both in government and in the private sector, following a series of devastating attacks last year, including Both ransomware attacks targeted fuel transportation company Colonial Pipeline and IT services company Kaseya.

In October last year, the White House hosted representatives from 30 countries around the world to try to limit cyber attacks. Meanwhile, law enforcement agencies have sought to deter hackers by arresting alleged ransomware operators across Europe.

Researchers at Chainalysis has tracked payments in recent years by analyzing cryptocurrency wallets linked to groups of ransomware hackers, including gangs known as Conti, DarkSide, and Evil Corp.

The alleged Russia-based ransomware hacker group Conti generated the most revenue in 2021, with at least $180 million from victims, researchers say.

Conti is one of many groups using a ransomware as a service business model, where affiliates can buy ransomware, use it to extort money, and offer Conti a portion of the ransom.

The Federal Bureau of Investigation (FBI) and the US Cybersecurity and Infrastructure Agency issued a warning about Conti last September, recording more than 400 attacks, including those that affected the Internet. affect law enforcement and health care agencies.

DarkSide, the group behind the attack on the Colonial Pipeline company, extorted victims with the second largest amount of money last year, as Chainalysis reports.

Colonial Pipeline said it paid $4.4 million for DarkSide. In June of last year, the US Department of Justice announced that it had recovered about $2.3 million of that.

The FBI previously said that victims from cyberattacks reported $29.1 million in damages caused by ransomware in 2,474 complaints in 2020.
