We’re happy to current the most recent situation of ESET Risk Report, which brings adjustments geared toward making its contents extra partaking and accessible. One notable modification is our new strategy to information presentation: fairly than detailing all information adjustments inside every detection class, our intention is to supply extra in-depth analyses of chosen, notable developments. For these in search of a complete overview of the telemetry information associated to every class, now we have included the complete set of charts and figures in a devoted Risk Telemetry part.
One other notable replace is the change in publication frequency, transitioning from triannual to a semiannual launch schedule. On this situation, we deal with the highlights of H1 2023, protecting the interval from December 2022 via Could 2023. When evaluating this era to H2 2022, we discuss with the timeframe from June 2022 to November 2022.
In H1 2023, we noticed traits highlighting cybercriminals’ exceptional adaptability and relentless pursuit of latest avenues to attain their nefarious targets – be it via exploiting vulnerabilities, gaining unauthorized entry, compromising delicate info, or defrauding people. One of many causes for shifts in assault patterns is stricter safety insurance policies launched by Microsoft, significantly on opening macro-enabled recordsdata. In a brand new try and bypass these measures, attackers substituted macros with weaponized OneNote recordsdata in H1 2023, leveraging the aptitude of embedding different recordsdata instantly into OneNote. In response, Microsoft readjusted, prompting cybercriminals to proceed exploring different intrusion vectors, with intensifying brute-force assaults towards Microsoft SQL servers probably being one of many examined approaches.
Our telemetry information additionally means that operators of the once-notorious Emotet botnet have struggled to adapt to the shrinking assault floor, probably indicating {that a} totally different group acquired the botnet. Within the ransomware area, actors more and more reused beforehand leaked supply code to construct new ransomware variants. Whereas this permits amateurs to interact in ransomware actions, it additionally permits defenders like us to cowl a broader vary of variants, together with newly rising ones, with a extra generic algorithm and detections.
Though cryptocurrency threats have been steadily declining in our telemetry – not even to be resurrected by the current improve in bitcoin’s worth – cryptocurrency-related cybercriminal actions proceed to persist, with cryptomining and cryptostealing capabilities more and more included into extra versatile malware strains. This evolution follows a sample noticed up to now, when malware resembling keyloggers was initially recognized as a separate menace, however ultimately turned a typical functionality of many malware households.
Taking a look at different threats targeted on monetary achieve, we noticed a comeback of so-called sextortion rip-off emails, exploiting individuals’s fears associated to their on-line actions, and an alarming progress of misleading Android mortgage apps masquerading as authentic private mortgage providers, making the most of weak people with pressing monetary wants.
