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.

Celebrating African Creativity: Made by Africa, Loved by the World’ Returns for Its Fifth Year
The “Made by Africa, Loved by the World” campaign is back for its fifth year, celebrating African creativity and global influence. This year’s theme, “Where Culture Meets Connection,” highlights how social media fosters conversations around cultural moments worldwide.
The campaign features three cinematic films premiering on the Meta Africa page, showcasing the groundbreaking work and personal stories of six dynamic African creatives.
These artists, from Nigeria, Kenya, Ghana, and South Africa, represent diverse disciplines, including rap, animation, dance, photography, fashion, and videography.
Here are some of the featured talents:
- Ladipoe (Nigeria) – A BET-nominated rapper known for blending global hip-hop with African rhythms.
- Fatboy Animations (Kenya) – An animation studio founded by Michael Muthiga, recognized by Forbes for its original African storytelling.
- Lisa Quama (Ghana) – A dancer who gained fame after appearing in Beyoncé’s “Already” music video.
- Gilbert Asante (Ghana) – A photographer and creative director featured in GQ and Glam Africa.
- David Tlale (South Africa) – A fashion designer whose bold designs have been showcased at major fashion events, including the Met Gala.
- Ofentse Mwase (South Africa) – A filmmaker with over 24 international awards for his unique visual storytelling.
Kezia Anim-Addo, Communications Director for Africa, Middle East & Turkey, emphasized that the campaign not only celebrates individual success stories but also showcases how culture and social media drive meaningful connections and inspiration.
Association of Telecommunications Companies of Nigeria (ATCON), has raised the alarm over a diesel supply crisis caused by an ongoing strike by the National Union of Petroleum and Natural Gas Workers (NUPENG).
Mr Tony Emoekpere, president, ATCON in a statement said that the fuel supply disruption is critically affecting telecom base stations, pushing them to the brink of a shutdown and threatening millions of mobile and internet users in the region.
“This strike, which stems from the persistent harassment of tanker and petroleum product drivers by police officers in Lagos State, has effectively halted all truck loading operations and fuel movements,” Emoekpere stated.
He explained that diesel supply to telecom infrastructure has been severely impacted, leaving critical sites with dangerously low fuel levels.
According to him, if urgent measures are not taken, the situation could escalate into a full-blown network blackout, disrupting essential services, including mobile and internet access, business operations, emergency response systems, and daily communications.
ATCON has called on the governors of Lagos and Ogun states to intervene immediately by facilitating the release of diesel from depots to telecom operators to prevent further deterioration of the situation.
“This is not just a telecom issue—it is a national emergency that could cripple economic activities and compromise public safety,” Emoekpere stressed.
The association also appealed to security agencies and petroleum unions to resolve the crisis swiftly to safeguard Nigeria’s connectivity and economic stability.
ATCON emphasised that a prolonged disruption in fuel supply to telecom infrastructure could have far-reaching consequences for both businesses and individuals who rely on stable communication networks for daily operations.
In 2023, Nigerians spent a total of about ₦5.3 trillion on telecommunications services, which includes calls, data, SMS, and other telecom services, according to the Leadership.
Specifically for voice calls, Nigerians made approximately 408.5 billion minutes of local calls, generating around ₦3.28 trillion from outgoing calls and ₦3.23 trillion from incoming calls, totaling about ₦6.51 trillion in call-related revenue according to projections based on 2023 call volumes and tariff data.
However, the ₦5.3 trillion figure represents the overall telecom sector revenue, with voice calls being a major component but also including data and other services.
For individual spending, MTN subscribers spent an average of ₦2,508 monthly on voice calls in 2023, showing a 14.4% increase from 2022, while Airtel customers spent about ₦1,694 monthly on voice calls.
Total telecom spending (calls, data, SMS, etc.): ₦5.3 trillion in 2023
Estimated revenue from voice calls alone: around ₦6.5 trillion based on call minutes and tariffs
Average monthly spending on calls per subscriber: ₦1,694 to ₦2,508 depending on the network
