Whereas nation-state operations and espionage claimed the highlight in 2020, practically 80% of intrusions involving an attacker at a keyboard had been associated to cybercrime, safety companies agency CrowdStrike states in its annual “International Menace Report.”
In actual fact, cybercriminal teams have moved away from automated assaults and towards intrusions involving handbook hacking and concentrating on massive enterprises, a method often called big-game searching. For instance, the Fin7 group — often called Carbon Spider in CrowdStrike parlance and Carbanak to some safety corporations — traditionally has compromised point-of-sale terminals and stolen payment-card information in huge breaches however now has adopted big-game searching strategies and ransomware assaults, CrowdStrike states within the report.
Cybercrime has turn into so worthwhile that even conventional nation-state attackers have performed some financially motivated assaults, says Adam Meyers, CrowdStrike’s senior vp of intelligence.
“They’re all seeing that there are greenback indicators in big-game searching and ransomware assaults,” he says. “Extra actors from different locations getting concerned in such assaults, reminiscent of Iranian menace actors who’re producing income by ransomware.”
CrowdStrike attributed about half of the assaults to particular actors. Of these, cybercrime — what CrowdStrike calls eCrime — made up 79%, whereas focused assaults accounted for 21%. In 2019, focused assaults accounted for considerably extra — 31% — of the attributed assaults.
“It is crucial that these adversary teams, and strategies for defending in opposition to their TTPs, [garner] a substantial amount of consideration within the coming yr,” the corporate states in the report. “Nonetheless, focused intrusions pushed by state-sponsored teams shouldn’t be uncared for.”
In a previous report, CrowdStrike analyzed the incidents it investigated on behalf of purchasers, discovering that 63% had been financially motivated, and 81% of these assaults concerned ransomware.
As a part of its deal with attributable cybercrime, CrowdStrike has created an eCrime Index (ECX) to trace the relative energy of adversaries targeted on cybercrime. The corporate has not but launched the small print of the way it calculates the numbers, however a chart on the corporate’s website signifies an approximate eightfold increase in the index since the end of December.
The rise within the value of varied cryptocurrencies accounts for a good portion of the regular enhance over the previous two months, Meyers says.
“The eCrime Index appears to be like at issues like ransom calls for, variety of ransoms, vulnerability exposures that we’re monitoring, cryptocurrency change charges — there’s a entire slew of various observables that we’re bundling collectively, and we’re producing this eCrime Index and monitoring it now,” he says. “It’s sort of an experiment of types that we’re opening as much as the world.”
One other pattern in 2020 is the dominance of healthcare as each a goal and a topic for social engineering. COVID-themed phishing turned a well-liked technique to flip customers right into a method into company networks. Typically, nation-state actors additionally focused the healthcare sector as a method of gathering information on authorities response and to steal info vaccine analysis, CrowdStrike says.
China, Iran, North Korea, and Russia all focused vaccine analysis and the healthcare sector, the corporate states within the report.
“The COVID-19 pandemic supplied legal actors with a novel alternative to make use of lure content material and social engineering strategies able to concentrating on every of those elements of human habits,” the report states. “As a subject, COVID-19 has international impression, 24-hour information protection and as of this writing, no clear finish in sight.”
The report additionally focuses on one other main attacker tactic: supply-chain compromises. Assaults on the third-party sources of software program turned the most important pattern by the tip of the yr, with nation-state attackers utilizing SolarWinds’ Orion community monitoring software program to get entry to that firm’s clients. CrowdStrike, which calls the attacker Stellar Particle and at present doesn’t attribute the assault to any explicit nation-state, highlighted that though such assaults are usually not new, they’re an efficient technique to flip a compromise of a provider into entry to each buyer community.
“The fact is that your gadgets are solely as safe because the least safe a part of the software program or growth atmosphere that you’re working,” Meyers says. “If you concentrate on all of the software program that’s updating within the background, and attackers are capable of compromise one piece, that’s terrifying.”
