Iranian hackers used ransomware instruments probably the most in 2021 to steal information and blackmail customers and firms, whereas hackers from China had been the largest exploiters of software program vulnerabilities around the globe in the identical interval, reveals a brand new report from cybersecurity agency CrowdStrike.
Iran-based hacker teams, based on the report launched on Friday, have been specializing in utilizing ransomware as their key instrument since late 2020. The usage of ransomware in world cybercrimes rose by 82% via the yr, the report added. By means of 2021, Iranian teams comparable to BlackShadow and Deus figured among the many largest ransomware customers on the planet – focusing on each Iranian and world corporations.
The teams in query had been seen to be conducting ‘lock and leak’ operations – the place the attackers lock down a system through the use of ransomware, and subsequently leak delicate firm data via their very own channels on the Darkish Net.
This isn’t the primary time that Iranian hackers have been linked to rising ransomware actions. In November 2021, a report by the Microsoft Risk Intelligence Centre (MSTIC) and Digital Safety Unit (DSU) famous that hacker teams based mostly in Iran had been more and more focusing on Indian corporations within the data know-how (IT) house – one thing that was not prevalent till not less than July 2021.
“Many of the focusing on is concentrated on IT providers corporations based mostly in India, in addition to a number of corporations based mostly in Israel and United Arab Emirates. Though totally different in approach from different current provide chain assaults, these assaults symbolize one other instance of how nation state actors are more and more focusing on provide chains as oblique vectors to realize their aims,” the Microsoft report acknowledged.
CrowdStrike stated that 2021 additionally noticed an increase within the variety of ransomware households, or teams of malware that assault a server or internet-facing firm infrastructure to lock them down and subsequently ask for ransom. The corporate noticed 2,686 ransomware assaults via 2021 – up from 1,474 recorded ransomware assaults in 2020.
“Given the success of those operations, Iran will probably proceed to make use of disruptive ransomware into 2022,” it stated.
Ransomware exploits have additionally contributed to a rising quantity of ‘felony whales’, or cryptocurrency wallets with holdings above $1 million – the place not less than 10 p.c of credited funds had been linked to blacklisted addresses. The 2022 Crypto Crimes Report by blockchain information tracker Chainalysis stated that as holdings in felony whales rose to over $25 billion in 2021, ransomware bounties contributed $30 million to this haul.
Chinese language hackers, in the meantime, made a shift of their general assault technique final yr – transferring from user-centric assaults to exploiting new, unpatched enterprise vulnerabilities. These unpatched, new exploits are referred to as ‘zero-day’ flaws, which stand for safety gaps which have remained unpatched in an present cyber structure.
To this finish, CrowdStrike says that whereas Chinese language hacking teams made two such exploits in 2020, the quantity rose to 12 exploits in 2021. India has been on the goal radar of Chinese language attackers, too.
In September 2021, a report by American cyber safety firm Recorded Future acknowledged that Chinese language government-backed hackers used a malware household named ‘Winnti’, which is typical to Chinese language hacker teams, to focus on organisations in India. The record of targets allegedly included the Distinctive Identification Authority of India (Uidai) – which points India’s Aadhaar identification doc. Uidai, although, had denied the claims behind the report.
