Cybercriminals Wiped Out Logs in 82% of Attacks – Sophos
Sophos, a global leader in innovating and delivering cybersecurity as a service, has released its Active Adversary Report for Security Practitioners, which found that telemetry logs were missing in nearly 42% of the attack cases studied. In 82% of these cases, cybercriminals disabled or wiped out the telemetry to hide their tracks. The report covers Incident Response (IR) cases that Sophos analyzed from January 2022 through the first half of 2023.
Gaps in telemetry decrease much-needed visibility into organizations’ networks and systems, especially since attacker dwell time (the time from initial access to detection) continues to decline, shortening the time defenders have to effectively respond to an incident.
“Time is critical when responding to an active threat; the time between spotting the initial access event and full threat mitigation should be as short as possible.
“The farther along in the attack chain an attacker makes it, the bigger the headache for responders. Missing telemetry only adds time to remediations that most organizations can’t afford.
“This is why complete and accurate logging is essential, but we’re seeing that, all too frequently, organizations don’t have the data they need,” said John Shier, field CTO, Sophos.
In the report, Sophos classifies ransomware attacks with a dwell time of less than or equal to five days as “fast attacks,” which accounted for 38% of the cases studied. “Slow” ransomware attacks are those with a dwell time greater than five days, which accounted for 62% of the cases.
When examining these “fast” and “slow” ransomware attacks at a granular level, there was not much variation in the tools, techniques, and living-off-the-land binaries (LOLBins) that attackers deployed, suggesting defenders don’t need to reinvent their defensive strategies as dwell time shrinks.
However, defenders do need to be aware that fast attacks and the lack of telemetry can hinder fast response times, leading to more destruction.
“Cybercriminals only innovate when they must, and only to the extent that it gets them to their target. Attackers aren’t going to change what’s working, even if they’re moving faster from access to detection.
“This is good news for organizations because they don’t have to radically change their defensive strategy as attackers speed up their timelines.
“The same defenses that detect fast attacks will apply to all attacks, regardless of speed. This includes complete telemetry, robust protections across everything, and ubiquitous monitoring,” said Shier.
“The key is increasing friction whenever possible—if you make the attackers’ job harder, then you can add valuable time to respond, stretching out each stage of an attack.
“For example, in the case of a ransomware attack, if you have more friction, then you can delay the time until exfiltration; exfiltration often occurs just before detection and is often the costliest part of the attack.
“We saw this happen in two incidents of Cuba ransomware. One company (Company A) had continuous monitoring in place with MDR, so we were able to spot the malicious activity and halt the attack within hours to prevent any data from being stolen. Another company (Company B) didn’t have this friction; they didn’t spot the attack until a few weeks after initial access and after Cuba had already successfully exfiltrated 75 gigabytes of sensitive data.
“They then called in our IR team, and a month later, they were still trying to get back to business as usual.”
The Sophos Active Adversary Report for Security Practitioners is based on 232 Sophos Incident response (IR) cases across 25 sectors from Jan. 1, 2022, to June 30, 2023. Targeted organizations were located in 34 different countries across six continents. Eighty-three percent of cases came from organizations with fewer than 1,000 employees.
The Sophos Active Adversary Report for Security Practitioners provides actionable intelligence on how security practitioners should best shape their defensive strategy.

Millions of citizens across Africa are being denied access to essential services due to the rapid imposition of biometric digital-ID systems, a new report by the African Digital Rights Network has revealed.
Biometric
The study, published by the Institute of Development Studies (IDS), found that citizens are increasingly required to provide biometric and personal information as a condition for accessing fundamental rights and government services such as voting, education, healthcare, and social protection payments.
According to the report, marginalised groups including persons with disabilities, the illiterate, and those unable to afford mobile data or electricity for phone charging face significant barriers to registration, deepening existing inequalities.
It noted that many citizens also refuse to enrol due to fears of data breaches and mistrust of governments, with biometric identifiers such as fingerprints, iris scans, and facial recognition raising privacy concerns.
Dr Tony Roberts, Research Fellow at IDS and co-editor of the report, said: “Worryingly, fundamental human rights, like education, healthcare and the right to vote are rapidly becoming conditional on enrolment in biometric digital-ID systems.”
He added that some visually impaired citizens are forced to pay others to help them use their digital-ID on mobile phones to access social protection payments.
‘Gbenga Sesan, Executive Director of Paradigm Initiative and co-editor of the report, said: “Many citizens do not want to enrol for a biometric digital-ID because they have good reason not to trust their governments with their biometrics and personal information.”
The report highlighted examples of massive data breaches and cases where personal data was used to surveil critics and opposition leaders.
It warned that most systems, estimated to cost at least US$1 billion across Africa, lack adequate legal frameworks, robust digital security, and accountability mechanisms for remedy when errors or breaches occur.
The authors concluded that governments must adopt strong legislation to protect citizens’ rights and privacy before rolling out biometric IDs, stressing that systems should be developed with citizen participation rather than imposed top-down.
The report, Biometric Digital-ID in Africa: Progress and Challenges to Date – Ten Country Case Studies, covers Botswana, Namibia, Malawi, Côte d’Ivoire, Senegal, Democratic Republic of the Congo, Liberia, Ethiopia, Egypt, and Tunisia.
Senator Natasha Akpoti has emerged as the most searched personality in Nigeria, according to Google’s 2025 Year in Search report, which highlights the interests and concerns that shaped the nation’s online activity during the year.
The report showed that political conversations dominated searches, with Akpoti’s prominence underscoring the intensity of national discourse. Nigerians also followed global developments closely, including the Israel-Iran War and the United States elections.
The country mourned the passing of former whose deaths prompted widespread searches recalling their legacies and contributions to national life.
Entertainment trends reflected Nigeria’s cultural vibrancy, with gospel hit “Oluwatosin (Jesus Is Enough)” by Tkeyz featuring Steve Hills topping charts, alongside Afrobeats collaborations such as Davido and Omah Lay’s “With You.” Director Kemi Adetiba and the local series “To Kill a Monkey” also drew significant attention.
Google noted that Nigerians displayed curiosity in language and lifestyle, decoding slang like “Labubu” and exploring recipes ranging from Pornstar Martini to traditional Chinchin.
Technology searches were led by interest in the iPhone 17 and Tecno Pop 10, reflecting the country’s embrace of new devices.
“This data offers a real-time window into the Nigerian psyche in 2025, showing a nation engaged, reflective, and creatively vibrant,” said Taiwo Kola-Ogunlade, Google’s Communications Manager for West Africa.
