26 May UAE companies are the GCC’S most targeted ransomware victims
Global cybersecurity leader Group-IB has unveiled its annual ransomware guidebook, which has seen the average ransom demand grow by 45% to reach $247,000.
The guide is the second in the series, It also notes the increase in greed by ransomware gangs. A record-breaking ransom of $240 million ($30 mln in 2020) was demanded by Hive from MediaMarkt. Hive and another 2021 newcomer to the Big Game Hunting, Grief, quickly made its way to the top 10 gangs by the number of victims posted on dedicated leak sites (DLS).
According to the report, between Q1 2021 and Q1 2022, the data belonging to 147 companies from the MEA region was uploaded on ransomware DLS. In the GCC region, 17 companies from the UAE had their data posted on DLS, followed by Saudi Arabia with 15 victim-companies, Kuwait with 6 and Qatar with five.
The new report also takes stock of the most up-to-date tactics, techniques, and procedures (TTPs) of ransomware threat actors observed across all geographic locations by Group-IB Digital Forensics and Incident Response (DFIR) team. In addition to the analysis of more than 700 attacks investigated as part of Group-IB’s own incident response engagements and cyber threat intelligence activity in 2021, the report also examines ransomware DLS.
Human-operated ransomware attacks have maintained the global cyber threat landscape lead by solid margins over the last three years. The rise of initial access brokers described in Group-IB’s Hi-Tech Crime Trends report and the expansion of Ransomware-as-a-Service programs (RaaS) have become the two main driving forces behind continuous growth of ransomware operations. RaaS made it possible for low-skilled cybercriminals to join the game to ultimately bring the victim numbers up.
Based on the analysis of more than 700 attacks in 2021, Group-IB DFIR experts estimated that the ransom demand averaged $247,000 in 2021, 45% more than in 2020. Ransomware evolved with more sophistication which is clearly visible from the victim’s downtime, which increased from 18 days in 2020 to 22 days in 2021.
RaaS programs started offering their affiliates not only ransomware builds, but also custom tools for data exfiltration to simplify and streamline operations. As such, the double extortion technique became even more widespread – sensitive victim data was exfiltrated as a leverage to get the ransom paid in 63% of cases analyzed by Group-IB DFIR team. Between the Q1’2021 and Q1’2022, ransomware gangs posted data belonging to more than 3,500 victims on DLS. Most companies whose data was posted on DLS by ransomware operators in 2021 were based in the United States (1,655), Canada (176), and the UK (168), while most organizations affected belonged to the manufacturing (322), real estate (305) and professional service (256) industries.
According to the report, between Q1 2021 and Q1 2022, the data belonging to 147 companies from the MEA region was uploaded on ransomware DLS. In the GCC region, 17 companies from the UAE had their data posted on DLS by ransomware threat actors, followed by Saudi Arabia with 15 victim-companies, Kuwait with 6 and Qatar with five.
Lockbit, Conti, and Pysa turned out to be the most aggressive gangs with 670, 640, and 186 victims uploaded on DLS respectively.
In the UAE specifically, the most active ransomware gang in 2021 was Lockbit with 6 companies posted on DLS between Q1 2021 and Q1 2022, followed by Prometheus (2), 54bb47h (1), Avaddon (1), Darkside (1) and others. Industry-wise, most of the affected companies in the UAE were from the real estate sector (3).
Bots are not what they seem
Exploitation of public-facing RDP servers once again became the most common way to gain an initial foothold in the target network in 2021 – 47% of all the attacks investigated by Group-IB DFIR experts started with compromising an external remote service.
Spear phishing emails carrying commodity malware on board remained in the second place (26%). Commodity malware deployed at the initial stage has become increasingly popular among ransomware actors. However, in 2021 the attribution of ransomware attacks became increasingly complicated since many bots such as Emotet, Qakbot, and IcedID were being used by various threat actors, unlike in 2020, when certain commodity malware families had strong affiliation with specific ransomware gangs.
Some ransomware gangs were seen trying very unconventional approaches: REvil affiliates leveraged zero-day vulnerabilities to attack Kaseya’s clients. BazarLoader, used in Ryuk operations, was distributed via vishing (voice phishing). Phishing emails contained information about “paid subscriptions”, which could allegedly be canceled by phone.
Oleg Skulkin, head of Group-IB DFIR team, said: “Given multiple rebrands forced by the law enforcement actions as well as the merge of TTPs due to the constant migration of affiliates from one Ransomware-as-a-Service (RaaS) program to another it is becoming increasingly challenging for security professionals to keep track of the ever-evolving tactics and tools of ransomware threat actors.
“To help corporate cybersecurity navigate through and prepare for ransomware incidents we outlined the main trends and TTPs changes and turned them into actionable insights mapped to and organised according to the MITRE ATT&CK® matrix.”
